Description

Deep seawater desalination system for mass production of domestic water

The deep seawater desalination system of this invention is to use high-pressure gravity sedimentation tanks to quickly precipitate and remove heavy metals, hardness impurities, chemical residues and other toxic substances to the human body, animals and plants in deep seawater; then use freezing method to separate "salt and water"; so that the produced "fresh water" and "brine" can remove toxic substances and preserve the nutrient-rich minerals and trace elements in deep seawater for use as water for people's livelihood, agriculture and industry.

"When sea ice is formed, saturated salt is extracted": When seawater freezes, it is actually fresh water freezing, which squeezes out the salt. Some of the salt that does not have time to flow away is wrapped in the gaps between ice crystals in the form of "halite" to form "salt bubbles". In addition, the gas that does not have time to overflow is wrapped in the gaps between ice crystals to form "air bubbles". Therefore, "sea ice" is actually a mixture of "fresh water ice crystals", "salt bubbles" and "air bubbles".

"Formation of sea ice": Ordinary pure water reaches its maximum density at 4℃, and begins to freeze at 0℃, which is the freezing point. However, because seawater contains salt, the temperature Imax when the density is the highest and the temperature I when it freezes are different from those of pure water, but depend on the salinity of seawater. When the salinity of seawater does not exceed 24.69 parts per thousand, Imax>I, that is, when the temperature of the surface seawater gradually decreases, the temperature of the surface seawater first reaches the temperature Imax with the highest density, so the surface seawater sinks and the lower seawater floats, forming convection. When the temperature continues to drop and approaches the freezing point I, the surface seawater will no longer sink, because the density of the seawater below is greater, so the surface seawater freezes directly; if the salinity exceeds 24.69 parts per thousand, Imax<I, at this time, the surface seawater first approaches the freezing point I when the temperature drops. At this time, the surface seawater sinks because its density increases when it cools down, while the warmer lower seawater floats up because of its lower density, forming convection until the seawater freezes; this way of seawater freezing is slow because the process goes back and forth many times.

"After water freezes into ice, its volume increases by 9%": The water molecules in ice are made up of hydrogen chains, and their -O-H-O- atoms are arranged in a straight line. Due to this regular arrangement, many gaps are formed between the water molecules in ice. Water molecules without hydrogen chains do not have this regular arrangement, and they will try to stack together tightly (close packing). For example, the hydrogen chain bonding rate of water at room temperature is about 50%, while that of ice is 100% (the higher the hydrogen chain bonding rate of water, the more gaps there are between molecules). In other words, ice has a higher regular arrangement than water, so the gaps between ice molecules are larger. Therefore, when the weight of water and ice is the same, the volume of ice is 9% larger. Seawater is salt molecules and water molecules, which are combined in the state of a mixture, that is, combined in a physical state. Its structure is very fragile. Water is composed of two elements, hydrogen and oxygen. The atomic mass of hydrogen is 1.00794u, making it the lightest element in the universe. The atomic mass of oxygen is 15.9994, ranking third after hydrogen and helium. The atomic mass of water is 17.00734. Salt, sodium chloride (NaCl), is composed of two elements, chlorine and sodium. The atomic mass of chlorine is 35.45 and the atomic mass of sodium is 22. .9898, the atomic mass of salt is 58.4398, and the density of salt is 2.165; if seawater freezes slowly, the atomic hydrogen chains of water molecules are regularly arranged in a straight line, and many gaps have been formed between water molecules. Because water freezes slowly, there is enough time for water molecules to precipitate all the salt molecules with heavy mass and density and precipitate them underwater, and they will not be wrapped in the gaps between ice crystals to form salt bubbles. , and pure freshwater ice is formed, floating on the water surface; similarly, ice cubes, crushed ice, frost, and ice water (liquid ice), if the temperature has reached below the freezing point of seawater, that is, below -2℃, because the water molecules have been regularly arranged, and all the salt molecules with high mass density have been precipitated, the water molecules have expanded and loosened, and the volume has increased by 9%, they all have the characteristics of freshwater ice and float on the water surface.

For the above-mentioned "hydroxide chain bonding configuration of water molecules", please refer to: Scientists from Peking University, with national funding, photographed the internal hydrogen bond configuration of water molecules for the first time (O-H...O). The research results were published in the form of an article in Nature Materials [Nature Materials DIO: 10.1038/nmat3848] on January 5, 2022, which can be proved.

According to statistics from the International Desalination Association (IDA), as of 2013, there are 17,000 desalination plants built around the world, producing more than 80 million tons of fresh water per day, and 300 million people cannot live without desalinated seawater.

According to the current "salt-water separation method" for seawater desalination, there are two mature processes, one is the "heating method" and the other is the "reverse osmosis method", which are explained as follows:

1. "Heating method": evaporate the seawater first, because the water vapor does not contain salt, and then cool it to get fresh water to remove the salt. Among them, there are multi-stage flash boiling, multi-effect evaporation, steam recompression and other methods. The heating method requires a lot of thermal energy, high production costs, limited output, and is often co-constructed with thermal power plants, using low-pressure steam emitted by the power plant's steam turbine as a cheap energy source, and the output is limited.

2. "Reverse osmosis": Currently, seawater desalination is mainly based on reverse osmosis (RO). Reverse osmosis has become the mainstream of seawater desalination production, with about 60% of desalination plants adopting it, and the proportion is increasing year by year. The reason is that the reverse osmosis process has the following advantages: fast plant construction speed, less energy consumption than heating method, easy operation, and the construction cost of large-scale reverse osmosis seawater desalination plants and the production cost of fresh water are also lower than other methods.

Reverse Osmosis (R.O.) is the most advanced and effective water purification method. It can effectively separate water molecules from salt molecules, hard impurities such as calcium and magnesium, heavy metals, chemical residues, viruses, bacteria, etc. in seawater, thereby producing safe drinking water.

However, the "reverse osmosis water production method" is aimed at the desalination production of "surface seawater" and still has many shortcomings, making it difficult to significantly increase production, mass produce, reduce costs, replace various water sources, and be widely used.

The reason is: the current reverse osmosis water production method has the following necessary processes: 1. First, introduce seawater into the storage tank for storage. 2. Perform preliminary filtration through a pre-filtration system. 3. Store the initially filtered seawater in the filtered water storage tank. 4. Further filter through the micro-filtration system. 5. Use a high-pressure pump to send the twice-filtered seawater to the reverse osmosis RO module for salt-water separation. 6. Recover part of the energy through energy-saving equipment (use the pressure of high-pressure brine to recover part of the energy). 7. Store fresh water in the fresh water storage tank. 8. Input fresh water into the tap water system. 9. Discharge brine into the sea.

The above process cannot be simplified or omitted, so there are many deficiencies as follows: 1. The pre-filtration and re-microfiltration treatment system is time-consuming and labor-intensive, so it is difficult to significantly increase the output. 2. Using a high-pressure pump to input seawater into the RO membrane cylinder to separate brine and fresh water is quite energy-consuming, and the cost is difficult to reduce. 3. The separation of brine and fresh water through the RO membrane cylinder is slow and difficult to mass produce. 4. The extremely precious minerals and trace elements in deep seawater will be completely removed after being filtered through the reverse osmosis RO membrane filtration method and cannot be retained.

The above-mentioned reverse osmosis water production method of seawater desalination production technology is aimed at the desalination of "surface seawater", and deep seawater is completely different. Deep seawater: generally defined as seawater between 200 meters and 4,000 meters.

The superiority of deep seawater can be summarized into the following five characteristics: (Source: Ministry of Economic Affairs Water Industry Information Network; the Ministry of Economic Affairs drafted the "Deep Seawater Resource Utilization and Industry Development Policy Guidelines" and sent it to the Executive Yuan, which was approved by the Executive Yuan on April 12, 2005, with the letter No. 0940011375, as a policy guide for the future development of Taiwan's deep seawater industry.)

1. Clearness and cleanliness: It is difficult for artificial pollution to reach deep seawater, which is one of the reasons why deep seawater is clean. In addition, during the sedimentation process of surface seawater, bacteria will gradually decrease with depth due to decomposition effects such as chemical acidification, sedimentation, drift diffusion, etc., and because the deep sea lacks residual organic matter and nitrate nitrogen and other nutrients required by bacteria, it is difficult for bacteria to survive and reproduce. Therefore, the content of various harmful bacteria or viruses that cause animal diseases in deep seawater is extremely rare, only one thousandth to one ten-thousandth of that in surface seawater. Furthermore, the organic matter remaining in deep seawater is quite resistant to the decomposition of residual organic matter by microorganisms, which is why the water quality of deep seawater is relatively stable, inorganic and clean in terms of microbiology or physical chemistry.

2. Rich in inorganic nutrients: or "rich in nutrients", in simple terms: rich in "inorganic nutrients". According to experts in the United States and Japan who study deep seawater, the inorganic nutrients such as nitrogen, phosphorus, silicon, and nitric acid contained in deep seawater are several to dozens of times higher than those in surface seawater on average. Due to insufficient light, photosynthesis is almost impossible, so the necessary nutrients required by plant plankton - nitrogen, phosphorus, silicon, nitric acid, etc. cannot be consumed, and a large amount of them accumulate in deep seawater, becoming water with particularly rich nutrients. This characteristic is called "rich in inorganic nutrients".

3. Low temperature stability: Because deep seawater is located in the deep sea where light cannot reach, the water temperature is lower than that of surface seawater and remains almost unchanged throughout the year. The low temperature is very stable, so it can be planned for a variety of uses, such as temperature difference power generation, breeding of cold water fish, etc. There are many other uses of cold energy to be developed.

4. Characteristics of trace minerals: If the water, salt and minerals in deep seawater are separated, high-content minerals and trace elements can be extracted; minerals include magnesium, calcium, potassium, etc., and trace elements include zinc, copper, boron, phosphorus, selenium, etc., totaling more than 80 kinds. In terms of medical functions, magnesium and calcium can be used to prevent osteoporosis, relieve diabetes and high blood pressure, and also inhibit the rise of neutral fat cholesterol. Among trace elements, the most valuable is selenium, because it is not easy to obtain in daily life. Once the human body lacks selenium, the probability of suffering from heart disease, diabetes and cancer is relatively increased. The trace element selenium, which is rich in deep sea water, can just make up for the deficiency of the human body and is of great help to human health.

5. Maturity of water molecules: Seawater below 300 meters below sea level is in a low temperature and high pressure environment all year round, so its water molecule structure is relatively small and belongs to quasi-nano-level micro-molecules. Its molecular structure is stable and it is not easy for water molecules to recombine and combine. Therefore, it has the characteristics of extremely stable and micro-molecular structure.

With the development of science and technology, one of the most important issues affecting mankind is the scarcity of water resources. Although humans have used seawater desalination technology to produce water for domestic use, they have only extracted "surface seawater" for desalination, benefiting a small number of people. However, the most valuable and important "deep seawater" that accounts for 95% of the earth's water resources is low-temperature, nutrient-rich, and the most fertile. Although the United States, Japan, and my country have already produced it on a small scale, they have not yet found a low-cost, large-scale, efficient, physical method to quickly produce large quantities of "fresh water" and "halite" and preserve it. The extremely precious minerals and trace elements in deep seawater can effectively replace existing water sources and be widely used as water for people's livelihood, agriculture and industry to maintain human health, improve human physique and prolong human life. It is urgent to let low-temperature seawater sprinkle on the earth, reduce soil temperature, improve soil quality, control deserts, turn the earth into black soil, increase food, solve the global warming crisis and maintain the living environment of animals and plants. It is a feasible and effective method that cannot be delayed and needs to be solved urgently.

In view of this, how to use modern technology to produce a large amount of deep sea fresh water at a low cost to replace the existing water sources, give full play to the five characteristics of deep sea water, benefit mankind and all animals and plants, and solve the water shortage crisis, global warming crisis, and food shortage crisis, is indeed a key issue of the top priority in water resource development. How can we leave 95% of the earth's low-temperature, nutrient-rich, and most fertile deep sea water idle in the sea and abandon it, so that water resources are insufficient, humans compete with each other, kill each other, and there will be no peace forever.

This invention, "Deep Seawater Desalination Water Mass Production System", effectively solves all the above-mentioned difficulties in the low-cost mass production of deep seawater. It can give full play to the five major characteristics of deep seawater and replace various water sources without minerals and trace elements as water for people's livelihood, so as to maintain human health, improve human physique and prolong human life.

Technical solution: In order to achieve the above-mentioned purpose and its effect, the present invention discloses a "deep seawater desalination and domestic water mass production system", including: a power generation system, a siphon mechanism, a pumping mechanism, a seawater storage tank, at least two high-pressure gravity sedimentation tanks, at least two first brine separators/or at least two second brine separators, a freshwater storage tank, and a brine storage tank, wherein: the power generation system: is the "wave buoyancy and gravity power generation system" invented by the inventor. Your Bureau approved the invention No. I692580 on May 1, 2020, as the power supply equipment of this "deep seawater desalination and domestic water mass production system", which effectively solves the cost problems faced by large energy consumption, high cost, and mass production.

The siphon mechanism: The long arm siphon extends 600 meters downward directly into the deep sea, and then extends upward to cross the top of the wall of the seawater storage tank before turning, and the short arm siphon extends downward to the bottom of the seawater storage tank; if the liquid level in the short arm siphon is lower than the liquid level in the long arm siphon, then when the siphon pumps water into the seawater storage tank by a pump of the pumping mechanism, the whole siphon is filled with seawater, and the siphon effect is established. When the pump is turned off, the deep seawater will continue to flow into the seawater storage tank through the siphon and will not stop flowing; if the liquid level in the short arm siphon is lower than the liquid level in the long arm siphon, the siphon will stop flowing. When the liquid level is high, the seawater in the seawater storage tank will flow back to the deep sea. At this time, the deep seawater must be pumped into the seawater storage tank by means of the pumping mechanism. The pumping mechanism is used to supplement the insufficient siphon force of the siphon mechanism. That is, when the liquid level in the short arm siphon tube of the siphon mechanism is higher than the liquid level in the long arm siphon tube, and the water cannot be pumped into the seawater storage tank by means of the siphon force, the pumping mechanism must be started to pump water into the seawater storage tank. That is, the siphon force of the siphon mechanism is used to save the energy consumption of the pumping mechanism, thereby achieving the effect of energy saving.

The seawater storage tank: has the same length as the high-pressure gravity sedimentation tank, but its capacity must be larger than that of the high-pressure gravity sedimentation tank; due to its heavy weight, the seawater storage tank must be partially buried underground to ensure structural safety; at the bottom of the seawater storage tank, there are multiple large-caliber water pipes that directly connect to the bottom of the high-pressure gravity sedimentation tank; at the water inlet of each water pipe, there is an electric water inlet gate and a pump to quickly fill the high-pressure gravity sedimentation tank.

The high-pressure gravity sedimentation tanks are provided with at least two, i.e., the first high-pressure gravity sedimentation tank and the second high-pressure gravity sedimentation tank, and the capacity thereof is set according to the daily demand for fresh water. If the daily demand is 450,000 tons, the capacity of the high-pressure gravity sedimentation tank is set to 450,000 tons, i.e., 300 meters in length, 50 meters in width, and 30 meters in height; a semi-permeable membrane separation plate is provided at a height of 20 meters of the first high-pressure gravity sedimentation tank and the second high-pressure gravity sedimentation tank to separate the first high-pressure gravity sedimentation tank and the second high-pressure gravity sedimentation tank into: a first lower tank and a second lower tank, a first upper tank and a second upper tank; The first lower pool and the second lower pool are composed of the semipermeable membrane isolation plate to the bottom of the first high-pressure gravity sedimentation tank and the second high-pressure gravity sedimentation tank, i.e., the water depth is 10 meters to 30 meters; in this part, the gravity pressure of the water is P = 2 atmospheres P ₀ ~ 4 atmospheres P ₀ In this high-pressure gravity environment, precipitation is carried out, allowing toxic heavy metals, hard impurities, chemical residues, etc. to settle quickly under the influence of gravity. If these heavy metals, hard impurities, chemical residues with heavy mass and coarse particles violate the laws of nature and climb upward through the semipermeable membrane isolation plate, because the semipermeable membrane isolation plate is located at a depth of 10 meters, its lower pressure = side pressure = upper pressure = 2 atmospheres P ₀ , it will use a lower pressure of 2 atmospheres P ₀ to assist the semipermeable membrane isolation plate to block it from above, and will also use 2 atmospheres P The side pressure of ₀ assists the semipermeable membrane isolation plate to push it away from the side, and the gravity of these substances themselves is pulled downward by the earth's gravity, and the nano-scale pore size of the semipermeable membrane isolation plate blocks heavy metals with heavy mass and coarse particles, hard impurities, and chemical residual substances. It is difficult for them to climb up and penetrate through the semipermeable membrane isolation plate, and they slip into the first upper pool/or the second upper pool. The bottom of the first lower pool/or the second lower pool is directly extended from the seawater storage tank. The multiple water pipes turn downward, and an electric water gate is set at the outlet; the outer side of the bottom of the first high-pressure gravity sedimentation tank/and the second high-pressure gravity sedimentation tank is provided with a drainage electric gate and a seawater drainage pipe directly connected to the sea; The first upper pool/and the second upper pool: are formed from the semipermeable membrane isolation plate to the top of the first high-pressure gravity sedimentation tank/and the second high-pressure gravity sedimentation tank, i.e., the range from the water surface to a water depth of 10 meters; in this part, a plurality of large-caliber water pipes are provided, and the water inlet of each water pipe is provided with an inlet electric gate, a semipermeable membrane isolation pipe, and a pump; the total outflow of the first upper pool/and the second upper pool is equal to the total inflow of the first lower pool/and the second lower pool, so that the water level of the first high-pressure gravity sedimentation tank/and the second high-pressure gravity sedimentation tank always remains unchanged; the semipermeable membrane of the semipermeable membrane isolation pipe is the same as the semipermeable membrane of the semipermeable membrane isolation plate, and only filters toxic heavy metals, hard impurities, Except for chemical residues, salt, water, minerals and trace elements are all allowed to pass through and sent to the first salt water separator/or the second salt water separator, and the salt, water, minerals and trace elements are separated by freezing method.

The first high-pressure gravity sedimentation tank/and the second high-pressure gravity sedimentation tank: Both must be filled up before they can be used; one is used every day, and the other is cleaned and refilled for sedimentation for one day before being used the next day; that is, the new tank is used today, and the old tank that was used yesterday is used. The switch of the drainage electric gate of the seawater drainage pipe on the outside of the old tank is opened, and all the sewage in the old tank is discharged directly into the sea through the seawater drainage pipe; When the old pool is continuously drained, the sewage in the first lower pool/or the second lower pool is quickly drained, and the clean water in the first upper pool/or the second upper pool naturally flows vertically downward, and the water gravity naturally presses all downward to quickly flush and clean the semipermeable membrane isolation plate, and then flush and clean the first lower pool/or the second lower pool; at this time, the fresh water storage tank is provided with a semipermeable membrane cleaning pipe and a cleaning electric gate; the semipermeable membrane cleaning pipe is connected from The fresh water storage tank is connected to the top of each semipermeable membrane isolation pipe of the first upper tank/and the second upper tank, and the switch of the cleaning electric gate of the semipermeable membrane cleaning pipe is immediately turned on to start spraying water downward to quickly flush the semipermeable membrane isolation pipe; after the semipermeable membrane isolation pipe, the semipermeable membrane isolation plate, the first lower tank/or the second lower tank are all flushed and cleaned, and the water is drained; the switch of the drainage electric gate of the seawater drainage pipe is closed. , start to refill the old pool with water; the two high-pressure gravity sedimentation tanks are replaced back and forth over and over again. Every day, the semipermeable membrane isolation tube, the semipermeable membrane isolation plate, the first lower pool/or the second lower pool are all flushed and cleaned before refilling with water. Therefore, the semipermeable membrane isolation tube, the semipermeable membrane isolation plate, the first lower pool/and the second lower pool are always kept clean and will not be blocked to ensure stable and smooth operation of the system.

According to the Ministry of Economic Affairs' Water Conservancy Industry Information Network, the five superior characteristics of deep seawater are listed in Section [0016] of this manual: "1. Clarity and cleanliness: It is difficult for artificial pollution to reach deep seawater, which is one of the reasons why deep seawater is clean. In addition, during the sedimentation process of surface seawater, bacteria will gradually decrease with depth due to decomposition effects such as chemical acidification, sedimentation, drift diffusion, etc., and because the deep sea lacks residual organic matter and nitrate nitrogen, etc. The nutrients required by bacteria make it difficult for them to survive and reproduce. Therefore, the content of various harmful bacteria or viruses that cause animal and plant diseases in deep seawater is extremely rare, only one thousandth to one ten-thousandth of that in surface seawater. Furthermore, the organic matter remaining in deep seawater is quite resistant to the decomposition of residual organic matter by microorganisms, which is why the water quality of deep seawater is relatively stable, inorganic and clean in terms of microbiology or physical chemistry. ”

In summary, deep seawater is already quite clean. Even if there are still traces of residual heavy metals, hard impurities, or chemical residues, they can be quickly precipitated by high-pressure gravity in the high-pressure gravity sedimentation tank and removed by the nano-scale pores of the semipermeable membrane isolation plate and the semipermeable membrane isolation tube.

Since the existing surface seawater desalination system uses reverse osmosis RO membrane to separate fresh water and brine, it also removes extremely precious minerals and trace elements, resulting in the fresh water produced having no nutrients, which is a pity. Therefore, the pore size of the semipermeable membrane used in the semipermeable membrane isolation plate and the semipermeable membrane isolation tube should not be too fine. In addition to removing heavy metals, hard impurities, chemical residues and other heavy and coarse toxic substances, the deep seawater contains rich minerals including magnesium, calcium, potassium, etc., and trace elements including zinc, copper, boron, phosphorus, selenium and more than 80 elements, all of which are The water molecules and salt molecules have been in the deep sea with low temperature and high pressure for many years. The molecular structure is small and stable. It is not easy for the molecules to recombine and combine. It has the characteristics of stable and tiny molecular structure (please refer to the description of Sections [0017], [0018], [0019], and [0020] of this manual). Therefore, these precious nutrients must be preserved and pass through the semipermeable membrane isolation plate and the semipermeable membrane isolation tube into the first salt water separator. They cannot be discharged. The semipermeable membrane products that are more suitable are: 1. RO membrane (reverse osmosis): the water permeability is 0.0001~0.002 micron. 2. NF membrane (nanofiltration): pore size 0.0009~0.009 micron; 3. UF membrane (ultrafiltration): pore size 0.006~0.11 micron; 4. MF membrane (microfiltration): pore size 0.08~1.2 micron; There are many more, I would like to extract the more suitable parts for reference. Among all the semipermeable membranes, only the reverse osmosis RO membrane has the smallest pore size, which is between 0.0001 and 0.002 microns. If we compare it to human hair, the outer diameter of human hair is about 10 microns, which shows the precision of the pore size of the reverse osmosis RO membrane. However, the purpose of the high-pressure gravity sedimentation tank is only to remove the heavy metals, hardness impurities, and chemical residues with heavy mass and coarse particles from the deep seawater. Therefore, the third item UF membrane with a coarser pore size of 0.006~0.11 microns or the fourth item MF membrane with a pore size of 0.08~1.2 microns is used to preserve these precious nutrients.

The first salt-water separator is provided with an inner and outer shell. The outer shell is provided with a heat preservation film, a refrigeration compressor and a temperature controller. The heat preservation film can isolate the outside temperature and keep the temperature inside the machine constant. The refrigeration compressor can provide cold air to maintain a constant temperature environment of -2°C to -20°C inside the machine. The temperature controller can set the constant temperature inside the machine at will. The inner shell is provided with a heat preservation film, a refrigeration compressor and a temperature controller. A rotating barrel, the rotating barrel is driven by a second motor, driving a second transmission gear to rotate the rotating barrel; the barrel wall of the rotating barrel is provided with many fine holes, and the inner barrel wall is closely attached to a semipermeable membrane, and water molecules, minerals and trace elements with light and fine particles can pass through the semipermeable membrane and overflow from the fine holes of the barrel wall; salt molecules, minerals and trace elements with heavy and coarse particles cannot The water overflows through the semipermeable membrane; a blade wheel is arranged at the center of the rotary barrel, and two bearings are arranged above and below the blade wheel to fix the blade wheel and help the blade wheel to rotate stably; the blade wheel is driven by a first motor to drive a first transmission gear to rotate the blade wheel; a water inlet pipe is arranged on the top of the first salt-water separator, and the water inlet pipe is provided with a water inlet electric gate and a spray faucet; when the water inlet pipe The switch of the water inlet electric gate is turned on, and the spray faucet can adjust the seawater to spray downward into the water; because the temperature of deep seawater is originally maintained at a low temperature of about 4℃~7℃, the temperature inside the machine is set at -2℃~-20℃ below the freezing point of seawater. The cold air in the spray water mist machine can easily penetrate into the small water droplets in the water mist, causing the small water droplets to quickly cool down to the freezing point -2℃. ℃ or below, and turns into ice water (liquid ice); when the spray faucet starts to spray water, the first motor of the first salt water separator drives the first transmission gear to rotate the impeller wheel quickly, so that the ice water sprayed from the spray faucet flows quickly along with the impeller wheel, so that the ice water will not freeze instantly and maintain the state of liquid ice and continue to flow; the first salt water separator The capacity is 3 tons, and it takes 1 minute to fill up with 3 tons of seawater. When the seawater is filled up, the switch of the water inlet electric gate of the water inlet pipe is immediately closed, and the impeller continues to rotate for 10 to 20 seconds to make sure that all the water molecules have turned into ice water. At this time, the second motor drives the second transmission gear to rotate the rotating barrel quickly, and the ice water with expanded and loosened water molecules is pushed into the water by the centrifugal force of the rotating barrel. Water molecules, minerals and trace elements with light and fine mass are thrown out of the outer shell of the rotating barrel; while salt molecules, minerals and trace elements with heavy and coarse mass are intercepted by the semipermeable membrane of the rotating barrel and remain in the rotating barrel; when all water molecules, minerals and trace elements with light and fine mass are thrown out of the rotating barrel and stored at the bottom of the outer shell, That is, a fresh water electric gate opens the switch of the fresh water pipe to transport all the fresh water to the fresh water storage tank; at this time, the brine stored in the rotating barrel, that is, the heavy and coarse molecules of salt molecules, minerals and trace elements, is immediately opened by a brine electric gate to transport all the brine to the brine storage tank. The entire journey is estimated to take about 2 minutes.

The first salt water separator: the number of rows and units installed is set according to the daily demand for fresh water; if the capacity of each first salt water separator is set to 3 tons, and the output is once every 2 minutes, that is, 1.5 tons per minute; then, with the daily output of the high-pressure gravity sedimentation tank set to 450,000 tons, the following calculation is required: 450,000 tons ÷ 24 hours ÷ 60 minutes ÷ 1.5 tons/minute = 209 units need to be installed, then 11 rows are set, 21 units per row, a total of 231 units are installed, and 1 row of 21 units are installed extra, which means that the first salt water separator is shut down once a day to flush and clean the semipermeable membrane, avoiding Blockage affects the quality of the produced fresh water; the high-pressure gravity sedimentation tank is equipped with 11 large-caliber water pipes in accordance with the number of rows of the first salt water separator, which directly pass through the top of the 11 rows of the first salt water separator and are connected to the water inlet pipe of the first salt water separator downward using a three-way joint; the spray faucet of the water inlet pipe can also be adjusted to change the spray mode to spray water jets. The first salt water separator is shut down once a day, row by row, so that the spray faucet sprays water jets around the bottom to flush the semi-permeable membrane in the cleaning machine to avoid blockage and affect the quality of the produced fresh water.

Regarding the operating principle of the first salt water separator, please refer to the explanation in Section [0004] of this manual: "After water freezes into ice, its volume increases by 9%": The water molecules in ice are formed by hydrogen chains, and their -O-H-O- atoms are arranged in a straight line. Due to this regular arrangement, many gaps are formed between the water molecules in ice; water molecules without hydrogen chains do not have this regular arrangement, and they will be stacked as tightly as possible (close packing). For example, the hydrogen chain bonding rate of water at room temperature is about 50%, while that of ice is 100% (the higher the hydrogen chain bonding rate of water, the more spaces between molecules), that is, ice is more regularly arranged than water, so the spaces between ice molecules are larger, so when the weight of water and ice is the same, the volume of ice is 9% larger; seawater is salt molecules and water molecules, combined in the state of a mixture, that is, combined in a physical state, and its structure is very fragile; water is composed of two elements, hydrogen and oxygen. The atomic mass of hydrogen is 1.00794u, which is the lightest element in the universe, and the atomic mass of oxygen is 15.9994, which is only second to hydrogen and helium, ranking third. The atomic mass of water is 17.00734; while salt, sodium chloride NaCl, is composed of two elements, chlorine and sodium. The atomic mass of chlorine is 35.45, and the atomic mass of sodium is 2.35. The mass of water is 22.9898, the atomic mass of salt is 58.4398, and the density of salt is 2.165. If seawater freezes slowly, the atomic hydrogen chains of water molecules are regularly arranged in a straight line, and many gaps have been formed between water molecules. Because water freezes slowly, there is enough time for water molecules to precipitate all the salt molecules with heavy mass and density and precipitate them underwater, instead of being wrapped in the gaps of ice crystals to form Salt bubbles form pure freshwater ice, which floats on the water. Similarly, ice cubes, crushed ice, frost, and ice water (liquid ice) all have the characteristics of freshwater ice and float on the water if the temperature has reached below the freezing point of seawater, that is, below -2°C, because the water molecules have been regularly arranged and all the salt molecules with high mass density have been precipitated, the water molecules have expanded and loosened, and the volume has increased by 9%. "

In summary, the first salt water separator is set to an appropriate constant temperature below the freezing point based on the data obtained from actual tests, so that the water mist sprayed from the spray faucet instantly turns into ice water; the impeller rotates at an appropriate speed to keep the ice water in the state of liquid ice and continue to flow; the rotating barrel rotates at an appropriate speed to generate an appropriate centrifugal force to move the expanded and loosened water molecules The light and fine molecules of minerals and trace elements are blocked and screened by the appropriate pore size of the semipermeable membrane, thrown out of the rotating barrel and stored in the outer shell barrel; while the heavy and coarse molecules of salt molecules, minerals and trace elements are blocked by the semipermeable membrane and retained in the rotating barrel, and the salt and water are properly separated; if the fresh water produced is not satisfactory , some heavy and coarse minerals and trace elements are still insufficient, they can be extracted from the brine stored in the brine storage pool and added to the fresh water storage pool, so that humans can enjoy all-round nutritious natural tap water every day; according to, minerals are essential elements for the human body, any shortage of minerals will cause diseases, but the human body cannot produce or synthesize them by itself, and must be taken from drinking water and food. Only deep sea water has all-round minerals and trace elements. Even if they cannot be directly extracted from the separated fresh water, they can be extracted from the separated brine and added to the fresh water storage pool to maintain human health, improve human physique, and prolong human life.

The second salt-water separator is a device that eliminates the following equipment of the first salt-water separator: 1. The semipermeable membrane of the rotary barrel. 2. The fine holes on the barrel wall of the rotary barrel. 3. The second motor. 4. The second transmission gear; and adds the following equipment: 1. A large square hole is opened on the top of the rotary barrel and a large electric gate is installed. 2. A third motor. 3. A third transmission gear; when the switch of the refrigeration compressor of the second salt water separator is turned on, the appropriate temperature of the machine is set, and when the temperature in the standby machine reaches the temperature, the switch of the water inlet electric gate of the water inlet pipe is immediately turned on, and the spray faucet sprays water mist downward to start water intake. Because the temperature of deep seawater is originally maintained at a low temperature of about 4℃~7℃, the temperature of the machine is set at -2℃~-20℃ below the freezing point of seawater. The cold air in the spray water mist machine can easily penetrate into the small water droplets in the water mist, causing the small water droplets to quickly cool down to a temperature below the freezing point of -2°C and become ice water (liquid ice). At this time, the first motor of the second salt water separator drives the first transmission gear to rotate the impeller wheel quickly, so that the ice water sprayed from the spray faucet flows quickly along with the impeller wheel, so that the ice water will not freeze instantly and maintain the state of liquid ice to continue to flow. Assume that the capacity of the second salt water separator is 3 tons, and it is filled with 3 tons of seawater in 1 minute. When the seawater is filled, the switch of the water inlet electric gate of the water inlet pipe is immediately closed, and the impeller continues to rotate for 10-20 seconds to make sure that all the water molecules have turned into ice water; the speed of the impeller is then decelerated, which is like a brake, so that the flow rate of the ice water is slowed down and slowly stops steadily; at this time, the water molecules in the ice water have expanded and loosened, because the mass of water molecules is the lightest and densest The lowest temperature will float to the top layer. Other minerals, trace elements, and salt molecules are also at a temperature below the freezing point of -2°C. Therefore, the molecules of all elements are very stable. The molecules of all elements will be clearly layered and steadily precipitated under the water molecules according to their own mass and density. After actual testing, those minerals and trace elements are screened together with water molecules and taken out together with fresh water. At what height do they stay underwater? According to the height setting, the third motor is quickly turned on to drive the third transmission gear, and the large electric gate is quickly pulled down according to the set height, so that the fresh water, minerals, and trace elements floating on the upper layer are discharged from the rotating barrel and stored in the outer shell barrel; when the water molecules, minerals, and trace elements with light mass and low density are all discharged from the rotating barrel and stored at the bottom of the outer shell barrel, Then, a fresh water electric gate is used to open the switch of the fresh water pipe, and all the fresh water is transported to the fresh water storage tank; at this time, the brine remaining in the rotating barrel, that is, the molecules with high mass density of salt molecules, minerals and trace elements, is immediately opened by a brine electric gate. The switch of the brine pipe is transported to the brine storage tank. The entire journey is estimated to take about 2 minutes.

Similarly, if the fresh water produced is not satisfactory, some minerals and trace elements with high mass density still need to be added to the fresh water for human drinking. They can also be extracted from the brine stored in the brine storage tank and added to the fresh water storage tank, so that humans can enjoy all-round nutritious natural tap water every day to maintain human health, improve human physique, and prolong human life.

The present invention also discloses a "deep seawater desalination agricultural water and industrial water mass production system", including: a power generation system, a siphon mechanism, a pumping mechanism, a seawater storage tank, at least two high-pressure gravity sedimentation tanks, and a freshwater storage tank, wherein: the power generation system, the siphon mechanism, the pumping mechanism, the seawater storage tank, and the freshwater storage tank are the same as the corresponding equipment of the above-mentioned "deep seawater desalination domestic water mass production system"; The only difference is that the capacity of the high-pressure gravity sedimentation tank: in response to the huge demand for agricultural and industrial water, is based on the fresh water per The daily demand is set. If the daily production demand is 2.7 million tons, the total capacity of the high-pressure gravity sedimentation tank is set to 2.7 million tons, that is, the capacity of each high-pressure gravity sedimentation tank is set to 900,000 tons, that is, 300 meters long, 100 meters wide, and 30 meters high; there are four high-pressure gravity sedimentation tanks, three of which have a daily production of 2.7 million tons, one is a spare, and one is cleaned in turn every day, and the spare is supported by the cleaning every three days; the other equipment of the high-pressure gravity sedimentation tank is the same as the equipment of the "high-pressure gravity sedimentation tank" in the above-mentioned "deep seawater desalination and domestic water mass production system".

Since deep seawater is already quite clean, it becomes even cleaner after high-pressure gravity sedimentation in the high-pressure gravity sedimentation tank. As long as the heaviest and coarsest salt molecules are separated and removed together with heavy metals, hard impurities, and chemical residues by the semipermeable membrane isolation plate and the semipermeable membrane isolation tube, the remaining fresh water, minerals, and trace elements are both nutritious and fertile, and can all be used as agricultural and industrial water without any safety concerns. , omitting the freezing separation process of the first salt water separator and the second salt water separator, directly inputting the filtered fresh water into the fresh water storage tank, allowing the low-temperature sea water to sprinkle on the earth, lower the soil temperature, improve the soil quality, turn the earth into black soil, increase food, expand animal husbandry, plant forests, and control deserts, so as to solve the food shortage crisis, water quality source shortage crisis, global warming crisis, and maintain the living environment of animals and plants.

The following is combined with Figures 1 to 12 to further illustrate the specific implementation of the "deep seawater desalination system and components for mass production of domestic water" of the present invention. The deep seawater desalination system and components for mass production of domestic water of the present invention are not limited to the description of the following embodiments.

Embodiment 1:

This embodiment provides a specific implementation method of the "deep seawater desalination and domestic water mass production system", as shown in Figures 1 to 7, including: a power generation system 1, a siphon mechanism 2, a pumping mechanism (not shown in the figure), a seawater storage tank 3, at least two high-pressure gravity sedimentation tanks 4, at least two first brine separators 5A/or at least two second brine separators 5B, a freshwater storage tank 6, and a brine storage tank 7, wherein: the power generation system 1: is the "wave buoyancy and gravity power generation system" invented by the inventor, and your bureau approved the invention No. I692580 on May 1, 2020, as the power supply equipment of this deep seawater desalination and domestic water mass production system, effectively solving the cost problems faced by large energy consumption, high cost, and mass production.

The siphon mechanism 2: As shown in FIG1, the siphon mechanism 2 uses the siphon principle. The long arm siphon extends downward 600 meters directly into the deep sea, and then extends upward to cross the top of the wall of the seawater storage tank 3 before turning. The short arm siphon extends downward to the bottom of the seawater storage tank 3. If the liquid level in the short arm siphon is lower than that in the long arm siphon, the siphon pumps water into the seawater storage tank by a pump of the pumping mechanism. In the seawater storage tank 3, the entire siphon tube is filled with seawater, and the siphon effect is established. If the pump is turned off, the deep seawater will continue to flow into the seawater storage tank 3 through the siphon tube and will not stop flowing. If the liquid level in the short arm siphon tube is higher than the liquid level in the long arm siphon tube, the seawater in the seawater storage tank 3 will flow back to the deep sea. At this time, the deep seawater must be pumped into the seawater storage tank 3 by the pump of the pumping mechanism.

The pumping mechanism (not shown in the figure) is a pumping machine of the pumping mechanism, which is used to supplement the insufficient siphon force of the siphon tube mechanism 2; that is, when the liquid level in the short arm siphon tube of the siphon tube mechanism 2 is higher than the liquid level in the long arm siphon tube, and water cannot be pumped into the seawater storage tank 3 by means of the siphon force, the pumping machine of the pumping mechanism is started to pump water into the seawater storage tank 3; that is, the siphon force of the siphon tube mechanism 2 is used to save the energy consumption of the pumping machine of the pumping mechanism, thereby achieving the effect of energy saving.

The seawater storage tank 3: As shown in Figures 1 to 3, the length is the same as that of the high-pressure gravity sedimentation tank 4, but the capacity must be larger than that of the high-pressure gravity sedimentation tank 4; due to its heavy weight, in order to ensure the safety of the structure, the seawater storage tank 3 must be partially buried underground for safety reasons; a plurality of large-caliber water pipes 31 are provided at the bottom of the seawater storage tank 3, which are directly connected to the bottom of the high-pressure gravity sedimentation tank 4; an electric water inlet gate 33 and a pump 32 are provided at the water inlet of each water pipe 31, which can quickly fill the high-pressure gravity sedimentation tank 4.

The high-pressure gravity sedimentation tank 4 is provided with at least two, i.e., a first high-pressure gravity sedimentation tank 4A and a second high-pressure gravity sedimentation tank 4B; as shown in FIG. 1 to FIG. 3, the capacity thereof is set according to the daily demand for fresh water. If the daily demand is 450,000 tons, the capacity of the first high-pressure gravity sedimentation tank 4A and the second high-pressure gravity sedimentation tank 4B is set to 450,000 tons, i.e., 300 meters long, 50 meters wide and 30 meters high; at a height of 20 meters of the first high-pressure gravity sedimentation tank 4A and the second high-pressure gravity sedimentation tank 4B, A semipermeable membrane isolation plate 46 is provided to separate the first high-pressure gravity sedimentation tank 4A/ and the second high-pressure gravity sedimentation tank 4B into: a first lower tank A1/ and a second lower tank B1, a first upper tank A2/ and a second upper tank B2; the first lower tank A1/ and the second lower tank B1: as shown in FIG3, are formed from the semipermeable membrane isolation plate 46 to the bottom of the first high-pressure gravity sedimentation tank 4A/ and the second high-pressure gravity sedimentation tank 4B, that is, the water depth ranges from 10 meters to 30 meters; in this part, the gravity pressure of the water P=2 atmospheres P ₀ ~ 4 atmospheres P ₀ , in this high pressure gravity environment, precipitation is carried out, and toxic heavy metals, hard impurities, chemical residues, etc. are quickly precipitated under the influence of gravity. If these heavy metals, hard impurities, chemical residues with heavy mass and coarse particles violate the laws of nature and climb upward through the semipermeable membrane isolation plate 46, because the semipermeable membrane isolation plate 46 is located at a depth of 10 meters, its lower pressure = side pressure = upper pressure = 2 atmospheres P ₀ , it will assist the semipermeable membrane isolation plate 46 to block it from above with a lower pressure of 2 atmospheres P ₀ , and will also use 2 atmospheres P 0 The side pressure of ₀ helps the semipermeable membrane isolation plate 46 to push it away from the side. In addition, the gravity of these substances themselves is pulled downward by the gravity of the earth, and the nanometer-level pores of the semipermeable membrane isolation plate 46 block the heavy metals with heavy mass and coarse particles, hard impurities, and chemical residues. It is difficult for them to climb up and penetrate through the semipermeable membrane isolation plate 46, thus slipping into the first upper pool A2 and the second upper pool A3. The first lower pool A1 and the second lower pool B1 have multiple water pipes 31 extending directly from the seawater storage tank 3, which turn downwards and are each provided with an electric gate 34 for water discharge; the first high-pressure gravity sedimentation tank 4A and the second high-pressure gravity sedimentation tank 4B are provided with an electric gate 47 for drainage and a seawater drainage pipe 42 for seawater discharge, respectively, on the outer side of the bottom; An upper pool A2 and a second upper pool B2: As shown in FIG3, it is formed from the semipermeable membrane isolation plate 46 to the top of the first high-pressure gravity sedimentation tank 4A and the second high-pressure gravity sedimentation tank 4B, that is, the range from the water surface to a water depth of 10 meters; in this part, a plurality of large-caliber water pipes 41 are provided, and the water inlet of each water pipe 41 is provided with an inlet electric gate 45, a semipermeable membrane isolation pipe 44, a pump 43; the total outflow of the first upper pool A2/and the second upper pool B2 is equal to the total inflow of the first lower pool A1/and the second lower pool B1, so that the water level of the first high-pressure gravity sedimentation tank 4A/and the second high-pressure gravity sedimentation tank 4B always remains unchanged; the semipermeable membrane of the semipermeable membrane isolation tube 44 is the same as the semipermeable membrane of the semipermeable membrane isolation plate 46, and only filters out toxic heavy Except for metal, hard impurities, and chemical residues, salt, minerals, and trace elements will all be allowed to pass through and sent to the first salt-water separator 5A/or the second salt-water separator 5B to separate salt, water, minerals, and trace elements. As shown in Figures 1 to 3, the first high-pressure gravity sedimentation tank 4A/and the second high-pressure gravity sedimentation tank 4B must be filled together, =One is used every day, and the other is cleaned and refilled with sediment for one day before it is used the next day; that is, the new pool is used today, and the old pool that was used yesterday is used. The switch of the drainage electric gate 47 of the seawater drainage pipe 42 on the outer side of the bottom of the old pool is opened, and all the water in the old pool is directly discharged into the sea through the seawater drainage pipe 42; when the old pool is continuously drained downward, the water in the first lower pool A1/or the second lower pool B1 will be drained out soon, and the clean water in the first upper pool A2/or the second upper pool B2 will naturally flow vertically downward, and the water gravity will naturally press downward to quickly flush and clean the semipermeable membrane isolation plate 46, and then the first lower pool A1/or the second lower pool B1 will also be flushed and cleaned; at this time, the fresh water storage tank 6 is provided with a semipermeable membrane cleaning pipe 63, a cleaning pipe 64, and a cleaning pipe 65; The semipermeable membrane cleaning pipe 63 is connected from the fresh water storage tank 6 to the top of each of the semipermeable membrane isolation tubes 44 of the first upper pool A2 and the second upper pool B2, and the switch of the cleaning electric gate 64 of the semipermeable membrane cleaning pipe 63 is immediately turned on to start spraying water downward to quickly flush the semipermeable membrane isolation tube 44; wait until the semipermeable membrane isolation tube 44, the semipermeable membrane isolation plate 46, The first lower pool A1 or the second lower pool B1 is completely flushed and cleaned to drain all the water; then the switch of the drainage electric gate 47 of the seawater drainage pipe 42 is closed, and water is refilled to fill the old pool; the two high-pressure gravity sedimentation tanks 4 are repeatedly replaced back and forth, and the semipermeable membrane isolation tube 44, the semipermeable membrane isolation plate 46, the first lower pool A1 and the second lower pool B1 are completely flushed and cleaned every day before refilling with water for use. Therefore, the semipermeable membrane isolation tube 44, the semipermeable membrane isolation plate 46, the first lower pool A1 and the second lower pool B1 can be ensured to be clean and will not cause blockage, so as to maintain the smooth operation of the system.

According to the Ministry of Economic Affairs' Water Conservancy Industry Information Network, there are five major characteristics of deep seawater. Please refer to the explanation in Section [0016] of this manual: "1. Clarity and cleanliness: It is difficult for artificial pollution to reach deep seawater, which is one of the reasons why deep seawater is clean. In addition, during the sedimentation process of surface seawater, bacteria will gradually decrease with depth due to decomposition such as chemical acidification, sedimentation, drift diffusion, etc., and because the deep sea lacks residual organic matter and nitrate nitrogen, etc. The nutrients required by bacteria make it difficult for them to survive and reproduce. Therefore, the content of various harmful bacteria or viruses that cause animal and plant diseases in deep seawater is extremely rare, only one thousandth to one ten-thousandth of that in surface seawater. Furthermore, the organic matter remaining in deep seawater is quite resistant to the decomposition of residual organic matter by microorganisms, which is why the water quality of deep seawater is relatively stable, inorganic and clean in terms of microbiology or physical chemistry. ”

In summary, deep seawater is already quite clean. Even if there are still a small amount of residual heavy metals, hard impurities, or chemical residues, they can be quickly precipitated by high-pressure gravity in the high-pressure gravity sedimentation tank 4 and removed by the nanometer-scale pores of the semipermeable membrane isolation plate 46 and the semipermeable membrane isolation tube 44.

Since the existing surface seawater desalination system uses reverse osmosis RO membrane to separate fresh water and brine, extremely precious minerals and trace elements are also removed, resulting in the fresh water produced having no nutrients, which is a pity; therefore, the semipermeable membrane used in the semipermeable membrane isolation plate 46 and the semipermeable membrane isolation tube 44 should not have a very fine pore size, in addition to being able to remove heavy metals, hard impurities, chemical residues and other heavy and coarse toxic substances, the deep seawater contains rich minerals including: magnesium, calcium, potassium, etc., and trace elements including: zinc, copper, boron, phosphorus, selenium and more than 80 elements, All of them have been mixed with water molecules and salt molecules, and have been in the deep sea with low temperature and high pressure all year round. Their molecular structures are small and stable, and it is not easy for molecules to recombine and combine. They have extremely stable and tiny molecular structure characteristics (please refer to: the descriptions of Sections [0017], [0018], [0019], and [0020] of this manual); therefore, these precious nutrients must be preserved and pass through the semipermeable membrane isolation plate 46 and the semipermeable membrane isolation tube 44 into the first salt and water separator, and cannot be discharged; the semipermeable membrane products that are more suitable at present are: 1. RO membrane (reverse osmosis): the water permeability is 0.0001~0.002micron. 2. NF membrane (nanofiltration): pore size 0.0009~0.009 micron; 3. UF membrane (ultrafiltration): pore size 0.006~0.11 micron; 4. MF membrane (microfiltration): pore size 0.08~1.2 micron; There are many more, I would like to extract the more suitable parts for reference. Among all the semipermeable membranes, only the reverse osmosis RO membrane has the smallest pore size, which is between 0.0001 and 0.002 microns. If we compare it with human hair, the outer diameter of human hair is about 10 microns, which shows the precision of the pore size of the reverse osmosis RO membrane. However, the purpose of the high-pressure gravity sedimentation tank 4 is only to remove the extremely small amount of heavy metals, hard impurities, and chemical residues in the deep seawater. Therefore, the pore size of the third item UF membrane is 0.006~0.11 microns, or the pore size of the fourth item MF membrane is 0.08~1.2 microns, in order to preserve these precious nutrients.

The first salt water separator 5A is provided with two layers of outer shells, as shown in Fig. 4 and Fig. 5. The outer shell is provided with a heat preservation film (not shown in the figure), a refrigeration compressor 58, and a temperature controller (not shown in the figure); the heat preservation film can isolate the temperature outside and keep the temperature inside the machine constant; the refrigeration compressor 58 can provide cold air to maintain a constant temperature environment of -2℃~-20℃ inside the machine; the temperature controller can set the constant temperature inside the machine at will; as shown in Fig. 4 and Fig. 5, the inner outer shell is provided with a rotating barrel 56, and the rotating barrel 56 is driven by a second motor 572B to drive a second transmission gear 571B to rotate the rotating barrel 56; the barrel wall of the rotating barrel 56 is provided with many fine holes, and the inner barrel wall is closely attached to a semipermeable membrane 55, and water molecules, minerals and trace elements with light particles can pass through the semipermeable membrane 55 and overflow from the fine holes of the barrel wall; salt molecules, minerals and trace elements with heavy particles can pass through the semipermeable membrane 55 and overflow from the barrel wall; The molecules cannot pass through the semipermeable membrane 55 and overflow; a blade wheel 54 is provided at the center of the rotating barrel 56, and two bearings 57 are provided above and below the blade wheel 54 to fix the blade wheel 54 and help the blade wheel 54 to rotate stably; the blade wheel 54 is driven by a first motor 572A to drive a first transmission gear 571A to rotate the blade wheel 54; as shown in FIG. 4 and FIG. 5, the first salt-water separator 5A is provided with a water inlet pipe 511, and the water inlet pipe 511 is provided with a The water inlet electric gate 512 and the spray faucet 53 are provided. The spray faucet 53 can adjust the seawater into a spray shape and spray the water downward. When the switch of the water inlet electric gate 512 of the water inlet pipe 511 is turned on, the spray faucet 53 adjusts the water into a spray shape and sprays the water downward. Since the temperature of the deep seawater is originally maintained at a low temperature of about 4°C to 7°C, the temperature of the constant temperature in the machine is set at -2°C to -20°C, which is below the freezing point of the seawater, the cold air in the spray water mist machine is cooled. It is easy to penetrate into the small water droplets in the water mist, so that the small water droplets are quickly cooled to a temperature below the freezing point of -2°C and become ice water (liquid ice); when the spray faucet 53 starts to spray water mist, the first motor 572A of the first salt water separator 5A drives the first transmission gear 571A to rotate the impeller 54 quickly, so that the ice water sprayed from the spray faucet 53 flows quickly along with the impeller 54, so that the ice water will not freeze instantly. The liquid ice is maintained to flow continuously; assuming that the capacity of the first salt water separator 5A is 3 tons, and 3 tons of seawater is filled in 1 minute, when the seawater is filled, the switch of the water inlet electric gate 512 of the water inlet pipe 511 is immediately closed, and the impeller 54 continues to rotate for 10 to 20 seconds to ensure that all water molecules have turned into ice water; at this time, the second motor 572B drives the second transmission gear 571B to rotate the rotating barrel 56 to rotate rapidly, and the water molecules that have expanded The expanded ice water, by the centrifugal force of the rotating barrel 56, throws the water molecules, minerals and trace elements with light and fine mass out of the outer shell barrel of the rotating barrel 56; while the salt molecules, minerals and trace elements with heavy and coarse mass are intercepted by the semipermeable membrane 55 of the rotating barrel 56 and remain in the rotating barrel 56; as shown in Figures 4 and 5, when the water molecules, minerals and trace elements with light and fine mass are all thrown out of the rotating barrel 56, the salt molecules, minerals and trace elements with heavy and coarse mass are intercepted by the semipermeable membrane 55 of the rotating barrel 56 and remain in the rotating barrel 56. After the water is stored at the bottom of the outer shell barrel, the switch of the fresh water delivery pipe 51 is opened by a fresh water electric gate 591, and all the fresh water is delivered to the fresh water storage tank 6; at this time, the brine stored in the rotating barrel 56, that is, the heavy and coarse molecules of salt molecules, minerals and trace elements, is immediately opened by a brine electric gate 592. The switch of the brine delivery pipe 52 is delivered to the brine storage tank 7. It is estimated that the whole journey takes about 2 minutes.

As shown in FIG1 , the number of rows and units of the first salt water separator 5A is set according to the daily demand for fresh water; if the capacity of each unit of the first salt water separator 5A is set to 3 tons, and the output is once every 2 minutes, that is, the production per minute is 1.5 tons; then, with the daily output of the high-pressure gravity sedimentation tank set to 450,000 tons, the following calculation is required: 450,000 tons ÷ 24 hours ÷ 60 minutes ÷ 1.5 tons/minute = 209 units need to be installed, then, 11 rows are set, 21 units per row, a total of 231 units are installed, and 1 row of 21 units are installed, which means that each row is shut down once a day to flush and clean the semipermeable membrane 55 of the first salt water separator 5A to avoid blockage that affects the production. Fresh water quality; As shown in FIG1 , the high-pressure gravity sedimentation tank 4 is matched with the number of rows of the first salt water separator 5A, and 11 large-caliber water pipes 41 are set, which directly pass through the top of the 11 rows of the first salt water separator 5A, and use a three-way joint to connect downward to the water inlet pipe 511 of the first salt water separator 5A; As shown in FIG4 and FIG5 , the spray faucet 53 of the water inlet pipe 511 can also be adjusted to change the spraying mode to spray water jets. The first salt water separator 5A is shut down once a day, and the spray faucet 53 sprays water jets around the bottom to flush the semipermeable membrane 55 in the cleaning machine to avoid blockage and affect the quality of fresh water produced.

Regarding the operating principle of the first salt water separator 5A, please refer to the explanation in this manual: "After water freezes into ice, its volume increases by 9%": The water molecules in ice are formed by hydrogen chains, and their -O-H-O- atoms are arranged in a straight line. Due to this regular arrangement, many gaps are formed between the water molecules in ice; water molecules without hydrogen chains do not have this regular arrangement, and they will be stacked as tightly as possible (close packing). For example, the hydrogen chain bonding rate of water at room temperature is about 50%, while that of ice is 100% (the higher the hydrogen chain bonding rate of water, the more spaces between molecules), that is, ice is more regularly arranged than water, so the spaces between molecules of ice are larger, so when the weight of water and ice is the same, the volume of ice is 9% larger; seawater is salt molecules and water molecules, combined in the state of a mixture, that is, combined in a physical state, and its structure is very fragile; water is composed of two elements, hydrogen and oxygen. The atomic mass of hydrogen is 1.00794u, which is the lightest element in the universe, and the atomic mass of oxygen is 15.9994, which is only second to hydrogen and helium, ranking third. The atomic mass of water is 17.00734; while salt, sodium chloride NaCl, is composed of two elements, chlorine and sodium. The atomic mass of chlorine is 35.45 and the atomic mass of sodium is 2.36. The atomic mass of salt is 22.9898, the atomic mass of salt is 58.4398, and the density of salt is 2.165; If the seawater freezes slowly, the atomic hydrogen chains of water molecules are regularly arranged in a straight line, and many gaps have been formed between water molecules. Because water freezes slowly, there is enough time for water molecules to precipitate all the salt molecules with heavy mass and density, and precipitate them underwater, and they will not be wrapped in the gaps of ice crystals to form Salt bubbles form pure freshwater ice, which floats on the water. Similarly, ice cubes, crushed ice, frost, and ice water (liquid ice) all have the characteristics of freshwater ice and float on the water if the temperature has reached below the freezing point of seawater, that is, below -2°C, because the water molecules have been regularly arranged and all the salt molecules with high mass density have been precipitated, the water molecules have expanded and loosened, and the volume has increased by 9%. "

In summary, the first salt water separator 5A is set to an appropriate constant temperature below the freezing point based on the data obtained from actual tests, so that the water mist sprayed from the spray faucet 53 instantly turns into ice water; the impeller 54 rotates at an appropriate speed to keep the ice water in the state of liquid ice and continue to flow; the rotating barrel 56 rotates at an appropriate speed to generate an appropriate centrifugal force to move the expanded and loosened water. The light and fine molecules of the semipermeable membrane 55 are screened by the appropriate pore size of the semipermeable membrane 55, thrown out of the rotating barrel 56, and stored in the barrel of the outer shell; while the heavy and coarse molecules of the salt molecules, minerals and trace elements are intercepted by the semipermeable membrane 55 and retained in the rotating barrel 56, and the salt and water are properly separated; if the fresh water produced is not as good as human Note that if some heavy and coarse minerals and trace elements are still insufficient, they can be extracted from the brine stored in the brine storage tank 7 and added to the fresh water storage tank 6, so that humans can enjoy all-round nutritious natural tap water every day; Minerals are essential elements for the human body. Any shortage of minerals will cause diseases, but the human body cannot produce or replenish them by itself. To synthesize, it must be taken from drinking water and food. Only deep sea water has all kinds of minerals and trace elements, and its reserves are very rich. Even if it cannot be directly extracted from the separated fresh water, it can be extracted from the separated brine and added to the fresh water storage pool 6 to maintain human health, improve human physique, and prolong human life.

The second salt-water separator 5B, as shown in FIGS. 4 to 7 , is a device without the following equipment of the first salt-water separator 5A: 1. The semipermeable membrane 55 of the rotary barrel 56. 2. The fine holes on the barrel wall of the rotary barrel 56. 3. The second motor 572B. 4. The second transmission gear 571B; and the following equipment is added: 1. A large square hole is opened above the rotary barrel 56, and a large electric gate 59 is installed. 2. A third motor 581. 3. A third transmission gear 582; As shown in Figures 6 and 7, when the switch of the refrigeration compressor 58 of the second salt water separator 5B is turned on, the appropriate temperature of the machine is set, and when the temperature in the standby machine reaches the constant temperature, the switch of the water inlet electric gate 512 of the water inlet pipe 511 is opened immediately, and the spray faucet 53, the water mist sprayer starts to take in water. Since the temperature of deep seawater is maintained at a low temperature of about 4°C to 7°C, the temperature inside the machine is set at -2°C to -20°C, which is below the freezing point of seawater. The cold air inside the sprayer can easily penetrate into the small water droplets in the water mist, causing the small water droplets to quickly cool down to a temperature below the freezing point of -2°C and become ice water (liquid ice). At this time, the first motor 572A drives the first transmission gear 571A to rotate the impeller wheel 54 to rotate rapidly, causing the spray faucet 5 The ice water sprayed in flows rapidly along with the impeller 54, so that the ice water will not freeze instantly, and maintain the state of liquid ice and continue to flow; assuming that the capacity of the second salt water separator 5B is 3 tons, and 3 tons of seawater is filled in 1 minute, when the seawater is filled, the switch of the water inlet electric gate 512 of the water inlet pipe 511 is immediately closed, and the impeller 54 continues to rotate for 10 to 20 seconds to ensure that all water molecules have turned into ice water; the speed of the impeller 54 is immediately reduced, which is like a brake, so that the flow rate of the ice water is reduced and stopped smoothly. At this time, the water molecules of the ice water have expanded and loosened. Since the water molecules have the lightest mass and the smallest density, they will float on the top layer. Other minerals, trace elements, and salt molecules are also at the same temperature below the freezing point -2℃. Therefore, the molecules of all elements are very stable. The molecules of all elements will be clearly layered and steadily precipitated under the water molecules according to their own mass and density. After actual testing, those minerals and trace elements are screened together with water molecules and taken out together with fresh water. At what height do they stay in the water? According to the height setting, the third motor 581 is quickly turned on to drive the third transmission gear 582, and the large electric gate 59 is pulled down according to the set height, so that the fresh water, minerals, and trace elements floating on the upper layer are discharged from the rotating barrel 56 and stored in the outer shell barrel; as shown in Figures 6 and 7, when the water molecules, minerals, and trace elements with light mass and low density are all discharged from the rotating barrel 56 and stored in the outer shell barrel After reaching the bottom, the switch of the fresh water delivery pipe 51 is opened by a fresh water electric gate 591, and all the fresh water is delivered to the fresh water storage tank 6; at this time, the brine stored in the rotating barrel 56, that is, the molecules with high mass density of salt molecules, minerals and trace elements, is immediately opened by a brine electric gate 592, and the switch of the brine delivery pipe 52 is delivered to the brine storage tank 7. It is estimated that the whole journey takes about 2 minutes.

Similarly, if the produced fresh water is not satisfactory, some minerals and trace elements with high mass density still need to be added to the fresh water for human drinking. They can also be extracted from the brine stored in the brine storage tank 7 and added to the fresh water storage tank 6, so that humans can enjoy all-round nutritious natural tap water every day to maintain human health, improve human physique, and prolong human life.
