Abstract
Description
Technical fields:
[0001] This invention relates to a solar-powered seawater purification device that utilizes a composite film solar cell array that can fully absorb infrared, visible, ultraviolet, and X-rays from sunlight to convert them into electrical energy, providing 380V power to seawater purification equipment and purifying seawater into pure water or high-purity water. Background technology:
[0002] Fresh water is one of the essential conditions for human survival. The human body is 70% water, and each person needs at least 2200 ml of fresh water per day. Without fresh water, humans cannot survive.
[0004] In my country, there are 640 large and medium-sized cities, of which more than 480 lack fresh water. The water shortage is even more severe on islands. There are 6,300 inhabited islands with an area of more than 5 square kilometers nationwide, and more than 59 million boats, which mainly rely on the mainland for fresh water.
[0005] In fact, the Earth is not short of water. The total volume of seawater is 1.386 billion cubic kilometers, accounting for 70% of the Earth's surface. Seawater is undrinkable; only 3% of the total seawater is drinkable freshwater. The remaining 97% is brackish water. Of this 3% freshwater, after deducting the water content of the polar ice caps, inland icebergs, air, rivers, and soil, the amount of freshwater available for human use is only 0.2% of the total water volume.
[0006] Purifying seawater to provide a source of water for human survival, production, and daily life is essential for human survival.
[0007] Currently, the best method for desalination seawater, both domestically and internationally, is reverse osmosis. However, this method requires a 380V AC power supply, making it unusable on islands and ships without it. Furthermore, it consumes a lot of electricity, is costly, and the produced "freshwater" still contains carcinogenic substances such as chloroform and carbon tetrachloride, making it unsuitable for consumption. Freshwater remains a serious problem hindering human production, daily life, and business development. Are there any methods that can solve the power shortage problem locally and provide better seawater purification solutions? Summary of the Invention:
[0008] The purpose of this invention is to overcome the aforementioned problems and provide a solution that can provide 380V power on-site and readily purify seawater into pure or highly purified water for human use, thereby addressing the difficulty of freshwater scarcity.
[0009] The objective of this invention is achieved as follows:
[0010] A composite film solar cell array with a conversion rate of 21.6% that can absorb infrared, visible, ultraviolet and X-rays from sunlight is used to convert them into 380V electricity to power seawater purification equipment.
[0011] Solar-powered seawater purification equipment consists of a composite membrane solar cell array, a coarse filter, a medium filter, a fine filter, and a resin purification device.
[0012] The 380V power generated by the composite film solar photovoltaic array provides power to the seawater purification equipment and water pump motor.
[0013] The coarse filtration unit consists of 2cm diameter gravel, 3mm diameter quartz sand, 0.5mm diameter specially made fine sand, and a stainless steel casing. During filling, the gravel is added in the following order: 2cm gravel, 3mm diameter quartz sand, and then the 0.5mm diameter fine sand, with each layer occupying approximately one-third of the casing's volume. The main function of the coarse filtration unit is to remove larger impurities such as silt, seaweed, and seagrass from the pumped seawater, resulting in cleaner seawater.
[0014] Medium-quality filtration unit: The medium-quality filtration unit is a funnel-shaped multi-layer filtration device, consisting of a titanium layer 2, a magnesium layer 3, an antimony layer 4, and a fine mesh. Seawater entering from the coarse-quality filtration unit flows through pipes into the medium-quality filtration unit for further purification, removing particles larger than 5 microns. Seawater flowing out of the medium-quality filtration unit exits through outlet 5 and enters the fine-quality filtration unit.
[0015] The fine filtration unit and the medium-quality filtration unit are tightly connected via piping. The fine filtration unit consists of an HD membrane and a dedicated membrane housing. The HD membrane is housed in a dedicated stainless steel pressure membrane housing. One end of the housing has an inlet pipe, and the membrane has a porous central tube connected to the outlet pipe. The main function of the fine filtration unit is to remove bacteria, viruses, and particles larger than 0.00001 from the water flowing through the medium-quality filtration unit, achieving a seawater purity of 99%, making it suitable for daily use as freshwater. However, this freshwater still contains pathogens.
[0016] Finally, seawater enters through pipes and is purified by a device made of anionic and cation exchange resins (anionic-cation exchange resin weight ratio of 3:1). This removes carcinogenic substances such as chloroform and carbon tetrachloride from the seawater, purifying it into pure water. The water is then conditioned with apricot kernel charcoal to create sweet, highly purified water. The water quality meets the national drinking water standards (GB / T-5750-2006) and (GB 5749-2006). This allows for the on-site supply of freshwater, pure water, and highly purified water to islands, ships, and coastal areas lacking freshwater, all at no cost, benefiting humanity.
[0017] Seawater passes through a coarse filtration device, a medium filtration device, a fine filtration device, and a purification device made of anionic and ionic resin materials. Finally, it is conditioned by a sweetening device made of apricot kernel charcoal materials. The resulting water is highly pure sweet water that can be consumed directly or used for medical purposes.
[0018] Advantages of this invention:
[0019] 1. By utilizing sunlight to provide 380V power on-site anytime, anywhere, islands and ships lacking electricity can obtain sweet, clean, and pure fresh water anytime, anywhere, eliminating the worries of not having power or fresh water.
[0020] 2. Applicable in any country or sea area worldwide where there is sunlight and seawater;
[0021] 3. Low water production cost: sunlight is free, instantaneous conversion into 380V electricity is free, and seawater is currently free, so the operating cost is close to zero.
[0022] 4. One solar photovoltaic seawater purification device with multiple outlets can simultaneously provide fresh water, purified water, and high-purity water.
[0023] 5. Solar power seawater purification equipment provides fresh water to islands and ships without water or electricity, while the photovoltaic component can also provide solar power to the islands and ships, and provide photovoltaic power to electrical equipment. Attached image description:

[0030] The following description, in conjunction with the accompanying drawings, further illustrates an embodiment of the solar-powered seawater purification device of the present invention:
[0031] Reference Figure 1The composite film solar cell is arranged in series and parallel to form an array 1 according to the power, current and voltage requirements of the water pump motor and other electrical appliances. It is placed on the array frame 2, and the electrode wires 3 are led out to pre-connect the solar power supply, seawater purification equipment electrical appliances and water pump motor.
[0032] Reference Figure 2 , Figure 2 This is a coarse filter device for solar seawater purification equipment. The coarse filter device consists of: 2cm diameter gravel (1), 3mm diameter quartz sand (2), 0.5mm diameter specially made fine sand (3), and a stainless steel casing (7). The casing has an inlet (4) at the top, a drain (6) at the rear top, and an outlet (5) at the bottom. The main function of the coarse filter device is to remove larger particles such as silt, algae, and seaweed from the seawater, making it cleaner for later use.
[0033] Reference Figure 3 , Figure 3 This is a medium-density filtration device: The medium-density filtration device is a funnel-shaped, multi-layered fine mesh filter, consisting of a titanium layer (2), a magnesium layer (3), an antimony layer (4), and a container (6). The inlet (1) is located at the top of the container (6), and the outlet (5) is at the bottom. The main function of the medium-density filtration device is to filter out particles larger than 5 micrometers from the seawater, reducing the particle size to less than 5 micrometers. The filtered water flows out from the outlet (5).
[0034] Reference Figure 4 , Figure 4 This is a fine-filtration device in a solar-powered seawater purification system. The fine-filtration device consists of an HD membrane 4 and a dedicated membrane housing 1. The stainless steel pressure membrane housing 1 has an inlet pipe 3 at one end, with the HD membrane 4 installed in the middle. The HD membrane has a porous central tube 6 in the middle, and an outlet pipe 5 at the other end of the membrane housing. The main function of the fine-filtration device is to remove bacteria, viruses, and particles larger than 0.00001 micrometers from the seawater flowing from the medium-quality filtration device after passing through the HD membrane 4, achieving a seawater purity of 99%, making it suitable for daily washing. However, this freshwater still contains carcinogenic substances.
[0035] Reference Figure 5 , Figure 5This purification device is made of anion and cation exchange resin particles. The resin types are: anion resin 3 (model: 201X7) and cation resin 2 (model: 100X7). The anion and cation resins are mixed in a weight ratio of 3:1 (3KG anion, 1KG cation) in a dedicated container 5. During filling, anion resin 3 is added first, followed by cation resin 2. Water, carrying pressure, flows into the device from the fine filter through the pipes. The water enters from the bottom inlet 6 of container 5, rising from the bottom of the purification device. It first enters the anion resin layer 3, then the cation resin layer 2. The pressurized water quickly mixes with the anion and cation resins, forming a mixture. As the water passes through this mixture, ion exchange occurs, removing carcinogens such as chloroform and carbon tetrachloride, resulting in highly purified water. This highly purified water is then conditioned using a conditioning device made of apricot kernel charcoal material, becoming sweet-tasting highly purified water.
[0036] Reference Figure 6 , Figure 6 This is a schematic diagram of the water purification process of a solar-powered seawater purification equipment. In the diagram, composite membrane battery modules are connected in series and parallel to form an array 1. The generated 380V power is transmitted to the water pump motor 3 via wire 2. The water pump motor 3, upon receiving power, immediately rotates and drives the water pump 10. The water pump 10 lifts seawater from the seawater inlet pipe 13 and applies pressure to the seawater. This pressurized seawater enters through the inlet pipe of the coarse filter device 4. Due to gravity, the seawater in the coarse filter device flows from top to bottom and is finally discharged from the outlet. Impurities remain on the top layer and are then discharged from the drain outlet on the rear side of the coarse filter device 4. Seawater flowing from the lower outlet of the coarse filter 4 enters the intermediate filter 6 through pipe 5. After undergoing multiple layers of filtration in the intermediate filter 6, the seawater becomes relatively clean, with particulate matter smaller than 5 micrometers. It then passes through pipe 11 into the fine filter 7, where bacteria, viruses, and other harmful substances larger than 0.00001 micrometers are filtered out. The seawater exiting the fine filter 7 then enters the resin purification device 8 through pipe 12, removing carcinogens such as chloroform and carbon tetrachloride. Finally, the purified water flows out from the outlet 9 of the purification device 8 and enters a conditioning device made of apricot kernel charcoal material, becoming sweet purified water.
[0037] The above solution uses solar power to power the seawater purification equipment, making it the optimal method for producing freshwater, purified water, and high-purity water on-site. If the water production site has a 380V AC power source, it can also be used to achieve the same water production effect. However, this would waste some electricity and incur higher production costs, costing 18 yuan per ton of freshwater, making it less effective than the above solution.
