Description

Obtained by molten salt electrolysis of fresh water or irrigation water discharged from seawater desalination process using electric energy obtained from windmills installed on floating ship decks or turbines installed in surface seawater under the deck The present invention relates to a system for producing, storing and transporting hydrogen generating metals or submarine minerals.

Currently, fossil energy such as oil, coal, and natural gas occupies most of energy resources, but carbon dioxide generated by the future depletion and combustion of these fossil fuels due to mass consumption of energy resources. As a result of the global environmental destruction caused by the problem, the reduction of carbon is an urgent issue as seen in the Kyoto Protocol.

Hydrogen is in the limelight as a storable clean energy that does not generate any environmental impact substances such as carbon dioxide. However, since a cylinder is necessary for storage, development of an energy source that is easy to carry is urgently needed, and one of them is research on hydrogen storage alloys. Considering this from a different point of view, it is also a proposal to generate as much hydrogen as necessary at the consumption place. The simplest hydrogen generation is the electrolysis of water using a photocatalyst, but the amount generated is small. At that point, sodium, calcium, potassium, etc. as hydrogen generating metals can be produced by simply pouring water, or magnesium, when hot water is poured, generate a large amount of hydrogen, explosively react with oxygen and burn. The metal sodium vapor used as a coolant for the fast breeder reactor Monju leaks, and this reacts with water to cause a fire accident. Furthermore, as shown in Non-Patent Document 1, Tokyo Kogyo proposes that hydrogen is generated by the reaction of metallic magnesium and hot water, which is converted into kinetic energy, and that the magnesium oxide in the fuel is reduced by solar excitation laser light. Made by Professor Takashi Yabe.

The present invention intends to efficiently ingest these hydrogen-generating metals from seawater inexhaustible using natural energy such as fluid energy and solar energy by wind and ocean currents. However, of the solar energy, the solar cell is not efficient for obtaining a large amount of power, and on the ocean, the salt crystal adheres to the light receiving surface, so that maintenance is difficult. . Here, the hydrogen generating metal means a base metal that generates hydrogen by reacting violently with water such as sodium, magnesium, calcium, and potassium. The amount of sodium in 1 kg of seawater is 11.05 g, magnesium is 1.32 g, calcium is 0.422 g, potassium is 0.416 g, and as in Non-Patent Document 2, magnesium refining in Japan started in 1958, one year earlier than aluminum. The production method was a method of electrolyzing magnesium chloride obtained by evaporating and concentrating bitter juice (magnesium chloride-containing hydrate) as a by-product during salt production with seawater. Furthermore, as shown in Patent Document 1, in 1933 (Showa 8), a method of chlorinating magnesium oxide to make anhydrous chloride and precipitating magnesium metal by molten salt electrolysis was conducted in September 1933 (Professor of Tokyo Institute of Technology). Patented by Kogoro Kato and Kenkichi Tachiki.

The molten salt melted at a high temperature exhibits high conductivity due to ionic conduction. In this molten salt electrolysis, unlike the electrolysis of an aqueous electrolyte solution, there is no generation of hydrogen because there is no water. For this reason, even a metal that is difficult to be cathode-deposited in an aqueous solution can be isolated. Further, magnesium, sodium, aluminum, etc., which have a strong bond with oxygen, are difficult to metallurgically by carbon reduction, and are produced by a molten salt electrolysis method. In practical application, we want to make the conductivity as high as possible and to carry out the reaction at the lowest possible temperature. According to Non-Patent Document 3, the melting point of sodium is 97.7 ° C and the boiling point is 882.9 ° C. The melting point of sodium chloride is as high as 801 ° C, but the melting point of sodium hydroxide is as low as 318 ° C. The Castner method, in which sodium hydroxide is subjected to molten salt electrolysis, is economical. In the Downs method, in which salt is directly electrolyzed with molten salt, the reaction temperature is lowered, so that about 40% of sodium chloride is mixed with about 60% of sodium chloride to bring the melting point to 600 ° C. According to this method, since the precipitated sodium contains a small amount of calcium, it is cooled to 110 ° C. and separated from both.

Magnesium has a melting point of 648.8 ° C. and a boiling point of 1090 ° C., whereas magnesium oxide has a high melting point of 2826 ° C. and a boiling point of 3600 ° C. However, the melting point of magnesium chloride is 714 ° C., which is a quarter of magnesium oxide. However, if the electrolysis temperature is lowered, the power required for molten salt electrolysis can be saved. For this purpose, it is necessary to increase the purity of magnesium chloride. For this reason, as disclosed in Patent Document 2, magnesium oxide or magnesium carbonate powder is added to an electrolytic bath salt having a reduced magnesium chloride concentration from an electrolytic tank for producing magnesium, and chlorine gas generated by electrolysis of magnesium chloride or Chlorination and electrolysis are repeated by reacting with a mixed gas of chlorine and carbon monoxide or phosgene and circulating an electrolytic bath salt. Examples of adding magnesium chloride to lower the melting point of magnesium oxide are disclosed in Patent Documents 3 and 4, and a method of electrolyzing magnesium oxide in a fluoride salt electrolyte is disclosed in Patent Document 5. In order to reduce the electric power used for molten salt electrolysis, a method for removing impurities in metal chloride is disclosed in Patent Document 6 in which a diaphragm made of graphite is disposed between an anode and a cathode of a molten salt electrolysis electrode. This is disclosed in Patent Document 7.

Regarding seawater desalination, there are evaporation method, cooling method, solvent extraction method, reverse osmosis method, leaving salt from seawater and removing only fresh water, conversely electrodialysis method, ion exchange resin that removes salt and leaves fresh water There is a law. In the case of producing salt from seawater, the power consumption per cubic meter of fresh water is 63 kWh in the multistage flash distillation method of the typical evaporation method and 10.6 kWh in the refrigeration method, but 0.69 kWh in the reverse osmosis method. Energy consumption is extremely small compared to other methods, and operation and maintenance are easy.

In reverse osmosis, when seawater is put in one of the containers separated by a semipermeable membrane and fresh water is put in the other, fresh water moves to the seawater side through the semipermeable membrane to make the salinity of both solutions uniform. To do. The pressure of this flow is called osmotic pressure, and the osmotic pressure of seawater is about 25 kgf / cm 2. At this time, when a pressure higher than the osmotic pressure is applied to the seawater side, fresh water is pushed out from the seawater side through the semipermeable membrane. Using this principle, fresh water is continuously made from seawater.

In order to desalinate seawater by the reverse osmotic pressure method, a high water pressure of 25 kgf / cm 2 or more is required. Therefore, Patent Document 8 discloses a method in which a reverse osmosis module is submerged in a water depth equal to or higher than a reverse osmosis pressure and fresh water permeated through a fresh water collecting pipe is pumped into the atmosphere. Patent Document 9 discloses that sand filtration treatment and flocculant injection can be omitted by taking seawater from a seawater layer having a depth of 100 meters or more prior to seawater desalination by reverse osmosis.

When the water depth is deeper than 200 m, the sunlight cannot reach and the atmospheric pressure is as high as 20 atmospheric pressure or higher. This depth of water is said to be deep ocean water, and there are significantly fewer bacteria than surface seawater. For this reason, fresh water obtained from deep water has cleanliness, maturity, and high minerality, and thus is used for food, beauty, medicine, and the like.

When irrigation is concentrated and the amount of seawater is less than 1/10, sodium chloride begins to crystallize and begin to precipitate. Eventually, small amounts of magnesium sulfate, magnesium chloride, potassium chloride, etc. crystallize. Since irrigation obtained by concentrating seawater by the reverse osmosis membrane method has precipitation of calcium carbonate, 3.3% seawater can be concentrated only at about 6%. On the other hand, ion exchange membrane dialysis can be concentrated to 20% using an electrodialysis membrane. Industrially, thousands of these electrodialysis membranes are used. Precipitated crystals are slightly different between the concentration of seawater by this ion exchange membrane dialysis method and the evaporation concentration method. Magnesium sulfate does not precipitate in the ion exchange membrane dialysis method, but precipitates in the evaporation concentration method. On the other hand, calcium chloride is precipitated by the ion exchange membrane dialysis method but not by the evaporation concentration method.

According to the United Nations Convention on the Law of the Sea, which came into force in 1994, coastal states can use continental shelves up to 200 nautical miles (370 km) as long as the seabed topography and geology meet certain conditions. A continental shelf can be set outside the nautical mile. This continental shelf is called an exclusive economic zone in the United Nations Convention on the Law of the Sea, and can develop non-living resources such as fishery resources and mineral resources. The hydrothermal deposits present inside and outside the depth of 2000 m are mud sulfides containing zinc, copper, lead, silver, etc., and are polymetallic sulfide deposits formed by hydrothermal action on the sea floor. Manganese craft is promising as a resource of manganese and cobalt, while manganese nodules are present on the seabed at a depth of 5000 m, whereas manganese craft is at a depth of 1500 to 2500 m.

High power is required for desalination of seawater, production of hydrogen-generating metals, or undersea drilling. For this reason, there is a high tendency to rely on natural energy that does not use fossil fuels. Natural energy power generation includes wind power, hydropower (tidal power), wave power, solar cells, solar heat, etc. Among them, wind power can be installed perpendicular to the ground surface, so it has a smaller installation area than other natural energy power generation installations. It can be used both day and night. Patent Documents 10 and 11 disclose that this wind power generation is used for electric power of a pressure pump for treating untreated water and seawater in a reverse osmosis plant. Similarly, Patent Document 12 discloses that wind power generation is used for power of a seawater pump for the purpose of desalination of seawater. Patent Document 13 discloses that wind power generation is used as electric power for electrolyzing fresh water obtained from seawater desalination equipment to produce hydrogen.

There are also attempts to desalinate seawater using wind power as a direct power source. Patent Document 14 discloses an osmotic seawater desalination apparatus in which an air compressor is connected to a wind turbine shaft, and compressed air from a compressed air tank acts on seawater to produce fresh water from seawater. Patent Document 15 discloses a wind-driven seawater desalination plant as means for sending seawater to an evaporation pipe for a seawater desalination plant.

Energy obtained by wind power (W) is swept area (A), air density ([rho), is given by When the wind speed ^{(V) W = AρV 3/} 2. Here, the density of air is 1.2 kg / m3 and the density of water is 1025 kg / m3. For this reason, if the flow of wind is replaced with the flow of water, 854 times as much energy can be obtained. There are Kuroshio Current (Japan Current) and Tsushima Current around Japan. The Kuroshio Current flowing through Tokara Strait, Cape Ashizuri, Cape Muroto, Cape Shiono Cape, Miyakejima and Mikurajima is 250km wide, 1000m deep, and 0.3 to 2m / second in velocity. It seems to be a water stream power source.

Natural energy such as wind power, hydropower, and solar heat mentioned above tends to be a good energy source that is friendly to the global environment and does not cause resource depletion, but these are all natural and geographical It is difficult to obtain a desired generated power depending on weather conditions and places. Then, the method of utilizing them on the ocean where natural energy such as solar energy, wind energy or tidal current is abundant has been proposed. Patent Document 16 discloses that electric power obtained by wind power generation is used to pump deep ocean water into a pool suspended on the sea. Patent Document 17 discloses that wind power generation is used for desalination by electrolysis of seawater. Patent Document 18 discloses wind power generation, wave power generation, ocean temperature difference power generation, and the like as power generation equipment that uses natural energy of a large floating structure installed on the sea. Patent Documents 19 and 20 include producing hydrogen and oxygen gas by electrolyzing water desalinated by electric power obtained by steam turbine power generation, wave power generation, wind power generation, etc. by solar heat on a movable floating body. Is disclosed. Wind turbines installed on the surface of floating or floating ship decks are preferably omnidirectional regardless of the wind direction. The inventor of the present application discloses vertical axis wind turbines that extract electric power from both wind energy and hydraulic energy in Patent Documents 21 and 22.

By integrating the above-mentioned references, seawater can be desalinated efficiently while using all natural energy, with a configuration that obtains the desired generated power and raw materials offshore as a method that is not restricted by natural or geographical conditions or weather conditions or locations. It is also possible to extract metals or mine seabed resources.

Conventional procurement of energy resources is limited to places where resources are abundant from the viewpoint of economy, and how to economically transport them to consumption areas has been a problem. However, modern industry has caused repeated over-exploitation of resources, and the resulting global depletion of resources has resulted in high resources, and the rise of resource-providing countries has increased its influence in the international community. Resource powers that threaten demanding countries are emerging. This is the very beginning of resource use. Fortunately, our country is surrounded by the sea, and considering the circumference of the continental shelf of 200 nautical miles, we have the potential to become an abundant resource country. Mineral resources in the seabed and seabed ground, mineral resources dissolved in seawater, energy sources such as ocean currents, tides, seawater temperature differences, animals and plants that live in the sea, drinking water and industrial water are also marine resources. The problem to be solved by the present invention is to economically manufacture these inexhaustible marine resources without using fossil fuels.

Up to now, seawater desalination and production facilities for water-soluble metals such as sodium and magnesium have been limited to the vicinity of thermal power plants in coastal areas, and these water-soluble metals have been said to be fossil for electricity like aluminum. In addition, there was a platform built offshore like an oil drilling well, but the enormous energy supplied to its development depended on oil. Recently, however, proposals have been made to use solar and wind energy abundant on the ocean. Patent Document 18 discloses the use of natural energy such as wind power generation, wave power generation, and ocean temperature difference power generation as a power generation facility for a large floating structure installed on the sea. Patent Documents 19 and 20 produce hydrogen and oxygen gas by electrolyzing fresh water obtained by desalinating seawater with electric power obtained by steam turbine power generation, wave power generation, wind power generation, or the like by solar heat. In patent document 16, the deep sea water is pumped up with the electric power obtained by wind power generation. Patent Document 17 discloses desalination by electrolysis of seawater using wind power generation. However, most of the seawater is desalinated and no attempt is made to produce metal by irrigation recovery, concentration, or molten salt electrolysis, or mining of mineral resources on the seabed. There is no marine resource energy production marine factory system that recycles spent metal oxides loaded on departure from the sea using molten salt electrolysis exhaust gas.

The present invention has been made in view of the above-described problems. That is, the object of the present invention is to produce hydrogen-generating metal, fresh water, liquid oxygen, seabed minerals by effectively using natural energy such as ocean current, wind energy or other fluid energy and concentrated solar heat. Mining, etc., landing these products at the port of call, loading oxides and hydroxides of used hydrogen generating metal from the land, and reusing the hydrogen generating metal using the waste gas from the marine factory. It produces metal aluminum by electrolyzing molten salt with bauxite that is built using abundant electric power obtained from ocean current power generation. As an offshore factory / cargo ship that performs all these tasks, or as a mother ship that continues production on the spot, it can reduce energy loss during production, storage, and transportation, and improve the efficiency of the entire system. To provide an offshore factory.

To achieve the above object, the marine resource energy production marine factory of the present invention consists of a large catamaran or monohull, and is omnidirectional on the deck to obtain a large amount of power from fluid energy at the offshore resource collection site. It has a number of vertical wind turbines that can be used to navigate the ocean while producing, float on the resource intake site, and moor. The ship is moored especially when performing ocean current power generation using ocean currents such as the Kuroshio Current. In order to perform ocean current power generation, a double hull is preferable to a single hull, and a plurality of omnidirectional vertical axis wind turbines are installed on the upper deck where two hulls of a catamaran are combined. Is characterized by a vertical axis turbine for ocean current power generation.

Means for producing and storing fresh water by desalinating seawater using reverse osmosis, evaporation or refrigeration methods using electricity produced offshore, and producing concentrated irrigation by electrodialysis of irrigation discharged as waste liquid. Send to the production process to recover hydrogen generating metals such as sodium, magnesium, calcium and potassium. Seawater desalination by the reverse osmosis membrane method is the most economical because there is no power consumption except that it requires power for a seawater injection pump. In the present invention, it is desirable to use a spiral-type module in which reverse osmosis membranes are layered. However, if the amount of power generated from fluid energy increases, multistage flash evaporation method or seawater is cooled to make ice, Use a freezing method that melts to obtain fresh water. Alternatively, sunlight is incident from a glass window of a container filled with seawater, and pure water is produced by passing the evaporated water vapor through heat from a cooling pipe such as Liebig. The outer pipe of the cooling pipe is passed through the seawater and deep water pumped for desalination and then sent to the desalination equipment. The fresh water obtained by these desalinations is stored, and the concentrated irrigation is used to recover the hydrogen-generating metal.

In order to desalinate seawater by the reverse osmosis membrane method, it is necessary to inject seawater. However, if this is performed in the deep sea, the pressurization pump can be omitted because the water pressure is high. Patent Document 18 discloses a method in which a reverse osmosis module is submerged to a depth equal to or higher than a reverse osmosis pressure, and fresh water permeated through a fresh water collecting pipe is pumped into the atmosphere. In the present invention, a spiral type reverse osmosis membrane module with pressure sensors for seawater, fresh water and irrigation composed of reverse osmosis membranes in the deep water layer is submerged, and concentrated irrigation and fresh water are separately pumped on the ship, Concentrated deep water and concentrated irrigation are continuously drawn using the water pressure at the bottom of the sea by providing a suction pump for suppressing the backflow of fresh water to the seawater and applying a suction pressure to counteract the osmotic pressure difference between the freshwater side and the irrigation side. After deep-frying and diverting these waters to ship equipment cooling and cabin cooling, deep ocean water is sent to storage tanks, and irrigation is sent to the thermal concentration process, where hydrogen-generating metals such as sodium, magnesium, calcium, and potassium are added. Served for recovery. The purpose of this patent is to desalinate seawater and take out hydrogen-generating metals. First, desalinate the seawater and further concentrate the discharged irrigation by the electrodialysis method, that is, the ion exchange resin method. Adopt the method to get.

Among hydrogen generating metals such as sodium, magnesium, calcium and potassium, sodium, calcium and potassium react violently with water to generate hydrogen. However, magnesium alone does not react with water, only with hot water. However, when it reacts with mercury to make magnesium amalgam, it reacts violently with water to generate hydrogen. Utilizing this property, when a small amount of magnesium amalgam is added to metallic magnesium containing water, or when water is dropped into a mixture of metallic magnesium and a small amount of magnesium amalgam, hydrogen reacts violently to generate hydrogen. The reason for this is that since the oxidizing power of magnesium is strong, the oxide film on the surface of magnesium works as a protective film for water. On the other hand, the use of mercury compounds can lead to environmental problems. Therefore, as a method not using mercury, magnesium can be used as a hydrogen-generating metal because hydrogen is generated by reacting violently with cold water by scratching metallic magnesium in water. As a result, sodium that reacts most strongly with water can be used as a hydrogen generation source for large-scale power generation facilities or as an alternative fuel for uranium in nuclear power generation, and magnesium can be used as a small-scale power generation facility or power source.

Concentrated irrigation discharged from seawater desalination is a treasure trove of hydrogen-generating metals. In order to roast this concentrated irrigation, the crystalline salt is deposited by the electric power obtained by the fluid energy, the heat generated from the molten salt electrolyzer or the concentrated sunlight. Each crystal salt is fractionated using this crystallization temperature. The separated crystalline salts are subjected to molten salt electrolysis using a large electric power obtained from fluid energy to generate a hydrogen generating metal at the cathode and chlorine gas at the anode. Of the hydrogen generating metals, sodium and potassium are stored in petroleum, and other magnesium and calcium are stored in a dry atmosphere. Chlorine generated as waste gas is used for chlorination of used hydrogen-generating metal oxides.

Used sodium oxide, magnesium oxide, or magnesium hydroxide that is shipped needs to be converted to chloride in order to facilitate molten salt electrolysis. The reaction with hydrogen chloride gas is convenient for forming a metal chloride. Therefore, hydrogen chloride is generated by reacting chlorine gas and hydrogen gas. Chlorine gas uses molten salt electrolysis waste gas, and hydrogen electrolyzes fresh water obtained by desalination of seawater. The other oxygen gas obtained by electrolysis of fresh water is compressed and stored in a container as liquid oxygen. The sodium chloride and magnesium chloride produced here are reused as raw materials for melt electrolysis. Here, since the melting point of used sodium hydroxide is lower than that of sodium chloride, sodium hydroxide can be directly subjected to molten salt electrolysis.

A metal having a strong ionization tendency can reduce an oxide of a metal having a weak ionization tendency. The used magnesium oxide that was shipped there was reduced to magnesium oxide by using metal sodium obtained by molten salt electrolysis of salt at an offshore factory to produce metal magnesium. It can react with hydrogen chloride produced in the factory to make sodium chloride, which can be electrolyzed with molten salt to produce metallic sodium.

The power required for molten salt electrolysis is enormous. However, most of them are used to melt metal chlorides, and the amount used for reduction by transfer of electrons involved in electrochemistry is relatively small. Therefore, in the present invention, both solar heat and electric power are used for molten salt electrolysis. Sunlight is 1 kW per square meter. Therefore, in the present invention, a molten salt electrolysis tank having a glass window for incident condensed sunlight is provided, the first step of concentration by solar heat of irrigation and production of distilled water, and concentrated base metal chloride The second step of performing molten salt electrolysis is performed at the same time. In the first step, pure water is produced by bringing a glass window through which sunlight is incident into contact with irrigation, evaporating the irrigation by solar heat, and passing it through a cooling pipe such as Liebig. At the same time, the concentration of irrigation increases with the passage of sunlight, sodium chloride is deposited, and bitter juice containing a large amount of magnesium chloride is taken out as a supernatant. The sodium chloride crystals and the bitter juice are separately transferred to the melting electrolysis tank in the second step, and the molten salt electrolysis is performed by passing an electric current through each of the metal chloride crystals thermally melted by irradiating condensed sunlight. . Here, in order to condense sunlight, the present inventor uses a manufacturing method of an aspherical mirror as disclosed in Patent Document 23 or a mirror for condensing a rectangular surface with a biconcave toroidal mirror disclosed in Patent Document 24. .

Deep-sea mining requires high power to move unmanned bulldozers and shovels on the seabed and to lift minerals on board. Therefore, mud such as zinc, copper, lead, silver, etc. present in manganese nodules and manganese classes containing manganese and cobalt in the submarine ground or in submarine hydrothermal deposits by the electric power obtained by fluid energy power generation, mainly ocean current power generation. Mineral resources such as sulfides can be mined.

Therefore, the present invention effectively uses mineral resources and marine mineral resources dissolved in the ocean to produce hydrogen-generating metals, fresh water, liquid oxygen, mining marine minerals, etc. The products are landed at the port of call, and oxides and hydroxides of used hydrogen-generating metal are loaded from the land, and the hydrogen-generated metal is regenerated using chlorine from the exhaust gas of the marine factory. By doing so, energy loss during production, storage, and transportation can be reduced, and as a result, the energy efficiency of the entire system can be improved.

As described above, according to the present invention, natural resources are effectively used offshore at the site where marine resources are collected, producing hydrogen generating metals, producing fresh water, producing liquid oxygen, mining and storing submarine minerals, etc. It is possible to obtain an excellent effect such that it can be performed without waste, energy loss during storage and transportation of the product can be reduced, and the efficiency of the entire system can be improved.

Hereinafter, an effective embodiment of the present invention will be described in detail with reference to FIGS. In the drawings, the same parts are denoted by the same reference numerals.

FIG. 1 is a schematic configuration diagram of an embodiment of the present invention. As shown in this figure, the marine resource energy production marine factory of the present invention has a wind power generating means 2 and an ocean current power generating means 3 or a solar thermal energy collecting means for generating electricity using fluid energy on a floating ship 1 floating on the ocean. 4, means 5 for producing fresh water by desalinating seawater by reverse osmosis or evaporation, means 6 for storing fresh water, means 7 for electrolyzing the obtained fresh water to produce hydrogen, fresh water Means 8 for liquefying oxygen generated by electrolysis, electrodialysis means 9 for dialysis of irrigation water as wastewater for desalination, and decoction concentrated with solar heat, electric heat or heat generated by molten salt electrolysis Means 10, means 11 for separating chlorides such as sodium, magnesium, calcium, potassium, etc. dissolved in the irrigated water, and electrolyzing the molten salt, and shipping on land Means 12 for storing used base metal oxides and hydroxides, means 13 for producing hydrogen chloride by reacting chlorine produced by molten salt electrolysis with hydrogen obtained by electrolysis of fresh water, and The resulting hydrogen chloride reacts with used magnesium oxide, magnesium hydroxide or used sodium peroxide to form a chloride, which is returned to the means 11 for electrolyzing the molten salt, and the molten salt is electrolyzed to produce waste gas chlorine. Make effective use. Used sodium hydroxide on land is directly used for molten salt electrolysis. And the storage means 14 which stores the hydrogen generating metals produced by the molten salt electrolysis means 11, and the mud such as zinc, copper, lead and silver in manganese nodules, manganese crusts or submarine hydrothermal deposits containing manganese and cobalt Means 15 for seabed mining sulfide and the like, means 16 for storing these sulfides, and spiral reverse osmosis membrane module 17 were submerged in the deep water layer and separated to collect fresh water and irrigation from the deep sea water. After irrigation and fresh water are separately pumped from the ocean, deep sea water and irrigation are continuously pumped using the water pressure at the bottom of the sea, and these waters are used to cool the equipment on the ship and to cool the cabin. It is a marine resource energy production marine factory characterized by sending water to means 6 for storing water and electrodialysis means 9 for irrigating ion exchange membrane dialysis, and loading and unloading marine resources on land 18.

In the marine resource energy production offshore factory of the present invention, the floating ship 1 in FIG. 1 means a monohull or catamaran such as a tanker, and produces fresh water or hydrogen-generating metal while navigating, floating, or moored. I can do it. FIG. 2 is a central cross-sectional view of a catamaran for explaining the arrangement of fluid energy power generation wind turbines and turbines, and FIG. 3 is for explaining the surface water flow and the position of the turbines under the catamaran deck. FIG. The catamaran ship left 19 and catamaran ship right 20 are arranged in two parallel lines, and the two boats are fixed by decks 21 and 25, so there is little shaking, high stability, and a wide deck can be taken off the ocean. It can be equipped with factory manufacturing facilities, solar furnaces or windmills. Moreover, since the moored catamaran is located along the ocean current 30, the ocean current is rectified between the two trunk vessels 19, 20, so that the wave resistance is low. Further, in order to increase the water receiving area of the water wheel 24, the vertical length of the water wheel is extended from the water line 23 to the position of the keel 26 or the inner keel. Then, the two fuselage ships 19 and 20 are fixed by a plurality of slender streamline-shaped rods (hydrofoils) 27 perpendicular to the keel 26 below the water line 23 of each fuselage ship 19 and 20 or the inner keel above it. ing. The lower part 25 of the deck and the slender streamlined ridge (hydrofoil) 27 are supported by bearings 29 so that the shaft 28 of the water turbine 24 is not deformed by the sea current. A plurality of the slender streamline-shaped dredgers (hydrofoils) 27 are arranged at regular intervals from the bow part to the stern part, and a plurality of turbines are also provided on one slender streamlined dredger (hydrofoil) 27. Make it work. In addition, the elongated streamline-shaped kite (hydrofoil) 27 is highly effective as a stable wing of a ship or as a ship. In this way, a large amount of power can be obtained from fluid energy at a resource collection site on the ocean. The ship is moored especially when performing ocean current power generation using ocean currents such as the Kuroshio Current. A catamaran is preferable to a monohull for ocean current power generation.

Fresh water 6 is produced using desalination equipment 5 by reverse osmosis, evaporation or refrigeration using seawater generated from fluid energy such as wind power generation 2 by the windmill 22 and fluid power generation 3 such as the Kuroshio by the watermill 24. The means for production and storage and the irrigation water as waste liquid are concentrated by electrodialysis method 9. In the present invention, seawater having a salt concentration of 3.3% is desalinated using a reverse osmosis membrane, but the discharged irrigation concentration is as low as 5.8%, 1.7 times that of natural seawater. However, since production of fresh water is also an important issue in the present invention, seawater is first desalted by the reverse osmosis membrane method in order to desalinate the seawater. This reverse osmosis membrane method is the most economical because it consumes no electric power except that it requires power for a seawater injection pump. So we use a spiral-type module with reverse osmosis membranes, but if the amount of power generated from fluid energy increases, the multistage flash evaporation method or seawater is cooled to make ice, and the ice is melted to obtain fresh water. Laws can be used in combination. The irrigation discharged from the desalination apparatus is adjusted to a salt concentration of 20% by an ion exchange dialysis apparatus (electrodialysis) 9. After the concentration of 20%, the electric power obtained by wind power generation 2 or ocean current power generation or the heat discharged by molten salt electrolysis is used to concentrate in the roasting device 10. Since the saturated solubility of sodium chloride is 26%, sodium chloride is first precipitated as crystals. This is transferred to the molten salt electrolysis apparatus 11, and the remaining bitter juice is further concentrated in the decoction 10, and the produced crystals are converted to magnesium. To the molten salt electrolysis apparatus 11. The power consumed here is about 7 volts, 9.5 amperes in the case of sodium and 10600 kWh per ton. In the case of magnesium, about 7 volts, 6.5 amperes flow, and 10,000 kWh per ton. These powers are supplied by wind power and ocean current power.

The molten salt electrolysis is performed by passing an electric current through each metal chloride crystal thermally melted by the sunlight (high-density light) 36 collected here. Here, the reason why the barrel-shaped (toroidal) double tube 40 is formed in a toroidal shape is to reduce the reflection loss at the incident window by putting incident sunlight vertically into the incident window. Here, for condensing sunlight, a biconcave toroidal mirror 39 disclosed by the present inventor in Patent Document 24 is used. The concave toroidal mirror 39 was made by placing flat glass on a heat-resistant brick cut into a toroidal surface in a high temperature furnace as disclosed in Patent Document 23 by the present inventor.

For desalination of seawater by the reverse osmosis membrane method, a pressure of 25 kgf / cm2 is required at most, but if this is performed in the deep sea, the pressure is high and the pressure pump can be omitted. As shown in FIG. 1, in the present invention, a set of spiral type reverse osmosis membrane modules 17 made of a reverse osmosis membrane placed in a pressure vessel is submerged in a 250 m deep water layer, and the pressure of each of seawater, fresh water and irrigation is calculated by a computer. Concentrated irrigation and fresh water are pumped separately on the ship under control, and a suction pump is used to reduce the reverse flow of fresh water to the deep seawater side and to apply a suction pressure to counteract the osmotic pressure difference between the fresh water side and the irrigation side. By preparing, deep sea water and concentrated irrigation are pumped up continuously using the water pressure at the bottom of the sea, and these waters are diverted for cooling equipment on the ship and cooling the cabin. Thereafter, the deep sea water is further concentrated in the storage tank 6 and the irrigation is further concentrated by the ion exchange resin method (electrodialysis) 9 and sent to the post-molten salt electrolysis 11 step after the brewing pot 10.

Of the hydrogen generating metals 14 such as sodium, magnesium, calcium, and potassium produced by the molten salt electrolysis 11 of FIG. 1, sodium, calcium, and potassium react vigorously with water to generate hydrogen. However, magnesium alone does not react with water, only with hot water. The reason for this is that since the oxidizing power of magnesium is strong, the oxide film on the surface of magnesium works as a protective film for water. So, put magnesium magnesium lumps and debris in the water, apply strong pressure between the lumps and debris, pull and break, scratch, and irradiate the laser light and sunlight collected by the lens, and the oxide film After ablation, the protective film of metallic magnesium was broken, and it became possible to react with cold water and generate hydrogen.

As shown in FIG. 1, the used oxides and hydroxides 12 used as hydrogen-generating metals on land are used effectively for the chlorine gas generated as the exhaust gas in the molten salt electrolysis 11 of the marine resource energy production marine factory. Since the warehouse of the floating ship 1 is empty, the ocean is loaded from the port 18 because of the abundance of wind power generation 2 and ocean current power generation 3 and solar heat 4 as energy for regeneration. Spent sodium oxide, magnesium oxide or magnesium hydroxide 12 needs to be converted to chloride to facilitate the molten salt electrolysis 11. In order to salify the base metal oxide, it can be reacted directly with chlorine gas, but in this case, carbon is required. This carbon causes global warming because it generates carbon monoxide and carbon dioxide. Therefore, hydrogen chloride gas 13 is used as a method not using carbon. Hydrogen chloride 13 is generated by reacting chlorine gas and hydrogen gas. Chlorine gas uses the waste gas of molten salt electrolysis 11 and hydrogen uses fresh water obtained by desalination of seawater generated by electrolysis 7. The other oxygen gas obtained by the electrolysis of fresh water is compressed and stored as liquid oxygen 8 in a container. The sodium chloride and magnesium chloride produced here are reused as raw materials for the molten electrolysis 11. Here, the melting point of sodium hydroxide is 318 ° C., which is significantly lower than the melting point of sodium chloride 801 ° C., so sodium hydroxide is directly subjected to molten salt electrolysis. The offshore factory produces about eight times as much metal magnesium as the metal power produced from the abundant electric power obtained from ocean current power generation 3 and molten salt electrolysis 11 of sodium chloride. Therefore, the used magnesium oxide 12 that was shipped was reduced to magnesium oxide by using metal sodium obtained in the molten salt electrolysis 11 of salt at an offshore factory to produce metal magnesium, and the oxidized sodium oxide was Similarly, sodium chloride can be produced by reacting with hydrogen chloride 13 produced at the offshore factory, and this can be produced by electrolysis 11 of molten salt to produce metallic sodium.

In hydrothermal deposits lying on the continental shelf, metal resources such as zinc, copper, lead and silver exist as mud sulfides. In addition, manganese nodules and manganese crusts containing manganese and cobalt accumulate in the seabed in the seabed near the sea, so it is said that they are picked up by an unmanned bulldozer or shovel instead of being mined by a rock drill or dynamite. Is considered appropriate. A large amount of electric power is required to lift the mineral up to the seabed mining 15 and the ship. Therefore, the mineral resources are stored in the shipboard storage 16 using electric power obtained from the wind power generation 2 or the ocean current power generation 3. The ocean current power generation 3 is particularly effective as this power.

As described above, according to the present invention, the production of base metal as a hydrogen-generating metal, the production of fresh water, the production of liquid oxygen on the ship at the sampling site by the effective use of natural energy for mineral resources and marine mineral resources dissolved in the ocean. Production of seabed minerals, landing of seabed minerals, etc., landing these products at the port of call, loading oxides and hydroxides of used hydrogen-generating metals from the land, and using this and the exhaust gas from offshore factories By regenerating the hydrogen-generating metal, not only energy loss during production, storage and transportation can be reduced, but also energy efficiency of the entire system can be improved.

According to the present invention, on a ship at a marine resource collection site, from abundant electric power obtained from wind power generated in situ or ocean current or natural energy such as solar heat, hydrogen generating metal such as sodium or magnesium, fresh water or liquid oxygen, etc. The product is landed at the port of call, the spent hydrogen-generating metal oxide is loaded from the land, and remanufactured at sea, eliminating energy loss during production, storage and transportation. Overall efficiency can be improved. This has led to a global depletion of resources and high resources, and the rise of resource-providing countries that accompanies this has not only calmed the current situation that is expanding its influence on the international community, but also the inexhaustible clean marine resources. Producing economically without using fossil fuels is an important measure for Japanese industries surrounded by the sea.
