Description

Modules for water purification

Technical field:

The invention relates to the technical field of water purification equipment, in particular to a replaceable, convenient, hygienic and efficient module for water purification.

Background technique:

With the continuous advancement of industrial civilization, more and more countries or regions are facing the crisis of water shortage. As a country with a large population, our country is facing more and more serious shortage of water resources. At present, most ordinary people drink the purified bottled purified water purchased, but it not only costs a certain amount of money to buy pure water, but also because the buckets and water dispensers used for bottled purified water are reused, so it is difficult to Ensure that the purified water you drink is fully up to the drinking standard. In addition, in some occasions or areas, there are direct drinking water pipes for people to drink directly. Human and financial resources cannot be fully popularized for us in a developing country.

On the other hand, people's research on water purification has never stopped, and as the current water resource crisis becomes more and more prominent, more and more people join this research field. There are two main traditional water purification methods: distillation and filtration. The method of purifying water by filtration is often used in large-capacity purification devices, but this method is difficult to remove harmful substances dissolved in water. For the purification of water by distillation, pure distilled water can be obtained, but this method has the following disadvantages: first, the speed is slow, because most of it is by heating the water to generate a large amount of water vapor, and then condensed The subsequent streams converge. The whole process is complicated and the processing capacity is small; secondly, the energy consumption is large, because liquid water needs to absorb a lot of heat when it becomes water vapor, which requires external heating, but when water vapor condenses into liquid water , needs to release a large amount of heat again, and these heats are usually directly released into the air, causing waste in vain; finally, drinking distilled water for a long time is not conducive to human health. Since the distilled water contains almost no minerals needed by the human body, long-term drinking of this water will cause rickets and other diseases due to the lack of certain trace elements. For the deficiency of the above-mentioned water purification method, someone has proposed a new method. For example, the patent No. is: the U.S. patent of 4216820 has just proposed a kind of technical scheme about heat exchange equipment. Below is additional relevant information about water purification equipment. The patent application number is: 01136187.5, which discloses a "water purification equipment and its method" in the public specification of the Chinese invention patent application, which adds ozone treatment and ultraviolet irradiation to the traditional filtration process, and passes through the strong oxidation of ozone and ultraviolet rays. The irradiation kills harmful substances in the water and purifies the water. See also Tsinghua University's application number is: 02146020.5 Chinese Invention Patent Application Publication, which discloses a "activated carbon fiber and electrokinetic synergistic purification of drinking water method and device", which is to apply an electric field on the activated carbon fiber filter material, The current is directly passed through the activated carbon fiber filter material, so that the water is purified under the action of the activated carbon fiber filter material and the electric field and flow field. The feature of the invention is to use the direct action of electric current to destroy the membrane structure of bacteria, so as to achieve the effect of killing bacteria and inhibiting the growth of bacteria.

Detailed ways:

The following descriptions are only specific embodiments of the present invention, and do not therefore limit the protection scope of the present invention.

See accompanying drawings 1-3, the present invention is a water purification device with a modular design, and the module can be made of plastic materials. The module should at least be provided with the first water inlet 11, water vapor generation

The space 3 and the water outlet 41 are provided with a steam generator 30 in the water vapor generating space 3, which can ensure that the module can realize the distillation of water. In order to improve efficiency in this embodiment, the module includes: a water inlet filter space 1 , a heat exchange space 2 , a water vapor generation space 3 and a water outlet filter space 4 . The water inlet filter space 1 , the heat exchange space 2 , and the steam generation space 3 are distributed from bottom to top in sequence, and the water outlet filter space 4 is located beside the water inlet filter space 1 .

The water inlet filter space 1 is provided with a first water inlet 11 , and the water to be purified will enter the water inlet filter space 1 through the water inlet 11 . A filter 5 is housed in the water inlet filter space 1, and the filter 5 can adopt fabrics such as gauze, cotton cloth, gauze, etc., and it will initially remove impurities in the water. After the water to be purified enters the water inlet filter space 1 from the first water inlet 11 , it will enter the inlet space 21 in the heat exchange space 2 after being filtered by the filter 5 . The heat exchange space 2 is divided into an inlet space 21 and an outlet space 22 by a heat exchange membrane 20 , wherein the inlet space 21 communicates with the inflow filter space 1 ; the outlet space 22 communicates with the outlet water filter space 4 . The heat exchange film 20 can be made of PC (polycarbonate) film material to improve heat conversion efficiency.

A steam generator 30 is provided in the steam generating space 3, and the steam generator 30 is two non-contact heating electrode sheets 301, 302, and the electrode sheets 301, 302 are respectively connected to electrodes of an external AC power supply. The steam generating space 3 is provided with a second water inlet 31 communicating with the entering space 21 and a steam outlet 32 communicating with the discharging space 22 . Wherein, the level of the port of the steam outlet 32 should be higher than the steam generator 30 to ensure that the water flow will not directly flow out of the steam outlet 32 . The water entering the space 21 enters the water vapor generating space 3 through the second water inlet 31. When the heating electrode sheets 301, 302 of the steam generator 30 are immersed in water, the heating electrode sheets 301, 302 are connected to the external power supply and are conducted by the water. , began to generate heat. In order to increase the conductivity of water in the water vapor generation space 3, an electrolyte material block 7 can be added to the water. Normally, this electrolyte material block 7 can be a salt bag, because sodium ions and chloride ions will be generated after salt is dissolved in water. , these ions will accelerate the heating effect of the heating electrode sheets 301, 302, and because the water vapor generated after heating will be discharged from the steam outlet 32, and the salt in the water will continue to crystallize and dissolve, almost without consumption, and can be used for a long time . After the water vapor enters the discharge space 22, it will condense to form a water flow, and this water flow will enter the outlet water filter space 4, and then filter and sterilize again. The filter 5 in the filter space can choose a filter with activated carbon material, and the water will be absorbed by the activated carbon. The harmful substances are adsorbed, and the water formed at this time becomes potable distilled water. But because long-term drinking of this type of water is not conducive to human health, minerals 6 are also placed under the filter 5 in the outlet water filtration space 4, that is, after the formed pure water passes through the minerals 6, certain trace mineral elements are dissolved in the water. water, which is good for people's health. In addition, the output filter space 4 is provided with a water outlet 41 . That is, the pure water added with trace mineral elements will flow out from the water outlet 41 for people to use.

In order to improve the heat conversion efficiency, the two sides of the heat exchange film 20 in the heat exchange space 2 are respectively formed with an inlet channel 210 and an outlet channel 220, that is, the inlet space 21 and the outlet space 22 are respectively separated to form an inlet channel 210 and an outlet channel 220, and the The channel 210 connects the water inlet filter space 1 with the second water inlet 31 ; the outlet channel 220 communicates the water outlet filter space 4 with the steam outlet 32 . As shown in FIG. 2 , the inlet channel 210 has a meandering shape to improve heat conversion efficiency. The outlet channel 220 has the same shape as the inlet channel, and usually adopts a meandering shape. See Fig. 4, which is a display diagram of the temperature of water at different positions of the module during a certain period of time during the working process of the present invention. When the water at normal temperature (10°C in this embodiment) enters the water inlet filter space 1 through the first water inlet 11, enters the water inlet space 21 of the heat exchange space 2 after being filtered, and enters water vapor in a detour along the inlet channel 210 Created in space 3. As the water flow continues to enter, when the heating electrode sheets 301, 302 of the steam generator 30 are immersed in water, the heating electrode sheets 301, 302 are connected to the external power supply, and the heating electrode sheets 301, 302 are turned on by water, and the electric energy is converted into heat energy. of water for heating. As the water temperature continues to rise, the evaporation rate continues to increase, and the generated water vapor will enter the discharge channel 220 in the discharge space 22 through the steam outlet 32 . Because there is only a heat exchange film 20 between the cold and hot channels, the water vapor in the outlet channel 220 will condense on the low temperature channel wall, and the heat released by it will be transferred to the inlet channel on the side of the heat exchange film 20 in time. In 210, the cold water entering the channel 210 is preheated. As the condensed water flows out along the discharge channel 220 , its heat is also continuously lost, and finally drops to normal temperature when it flows out from the water outlet 41 through the water outlet filter space 4 . Due to the continuous operation of the steam generator 30 , the heat generated by it will also continuously increase the temperature of the water entering the channel 210 . At the same time, the water in the discharge channel 220 is also continuously heating the water entering the channel 210, so that the water entering the channel 210 can quickly rise to the water temperature state shown in FIG. 4 . At this time, the steam generator 30 only needs to generate a small amount of heat to keep the whole module continuously producing pure water. In this way, the heat can be recycled to reduce energy consumption, which not only improves the purification efficiency, but also reduces the power consumption of the steam generator 30 due to the reduced energy consumption.

In addition, with the continuous conversion of heat, the water entering the space 21 will be continuously heated, which will generate a certain amount of gas, which may be generated by impurities contained in the water to be purified, in order to discharge these gases in time, then The upper end of the inlet channel 210 is formed with an exhaust port 211 reaching to the top of the module and communicating with the external space. When the gas produced by the water to be purified is continuously detoured along the inlet channel 210 and rises to the exhaust port 211, the gas will be discharged from the exhaust port 211, thus eliminating secondary pollution of the purified water by these gases. At the same time, with the continuous conversion of heat, the water entering the space 21 will be continuously heated. After a certain period of time, the temperature of the water entering the space 21 may rise to a higher temperature. At this time, the heat exchange cannot be completed. The steam generating space 3 is provided with a superheated water outlet 35 leading to the external space, and the superheated water outlet 35 is located between the steam generator 30 and the horizontal plane where the steam outlet 32 is located. When the water entering the space 21 is overheated like this, the overheated water outlet 35 is opened to discharge the water, which enters through the first water inlet 11 after external cooling. Or directly send the cooled water from the first water inlet 11 indiscriminately, even if the temperature of the water entering the space 21 is lowered.

5 and 6, the inlet channel 210 and the outlet channel 220 can also adopt the shapes shown in the figure, these shapes are conducive to the gas in the water can be discharged upward through the exhaust port 211 in time, and will not return, which can further improve the efficiency of water purification quality.

The present invention adopts a modular design, which can be quickly replaced when used with a water dispenser or other equipment, so as to eliminate the damage to the human body caused by the scale and other harmful substances accumulated inside the purification equipment after long-term use.
