Description

Technical Field

[0001] This invention relates to the technical field of hydrogen production and water electrolysis, specifically to a purification and filtration mechanism for hydrogen production and water electrolysis. Background Technology

[0002] Hydrogen production by water electrolysis is a process that decomposes water molecules into hydrogen and oxygen through electrolysis. In the process of hydrogen production by water electrolysis, the purity of water has a crucial impact on the yield and quality of hydrogen. However, existing hydrogen production by water electrolysis equipment still has some defects in use. Impurities in the water can affect the efficiency of the electrolysis reaction, resulting in low quality of hydrogen produced and even affecting the overall effect of water electrolysis.

[0003] To overcome the aforementioned shortcomings, existing technology 1 (Chinese Patent No. CN219526431U, Publication Date: August 15, 2023) discloses a novel water electrolysis generator, comprising a filter box, a filter assembly fixedly connected inside the filter box, a connecting pipe extending through one side of the filter box, a water pump extending through one end of the connecting pipe, a conduit extending through the output end of the water pump, and a cover plate extending through one end of the conduit. The cover plate has a groove on its surface and a cavity inside, with a snap-fit ​​assembly fixedly connected to the surface of the cavity. This novel water electrolysis generator, through the filter box and filter assembly, allows water to flow into the filter box through the inlet pipe. Large particles in the water are filtered out by the filter screen, suspended solids and sediment are filtered out by the filter cotton, and residual metal ions and residual chlorides are adsorbed and purified by activated carbon, thus purifying the water and effectively filtering the water to be electrolyzed. This invention improves the efficiency of subsequent water electrolysis processes, resulting in electrolyzed water with better quality. Existing technology two (Chinese patent CN220951445U, published on May 14, 2024) describes a multi-stage filtration electrolyzer, including a housing body. The filter element body and the fixed base are equipped with a convenient replacement mechanism on their surfaces, and the installation pipe and the fixed pipe are equipped with a quick assembly mechanism on their surfaces. The housing body contains a multi-stage filtration mechanism. This invention not only greatly improves the convenience of using the electrolyzer, allowing tap water to enter the housing body through the installation and fixed pipes while ensuring their stability during installation, but also enables the electrolyzer to filter, sterilize, and electrolyze tap water, resulting in clean and hygienic tap water that better regulates bodily functions. Furthermore, it ensures effective filtration of tap water, making the electrolyzer perform better on the treated water.

[0004] Existing technologies use multi-stage filter plates for filtration, but in practical applications, these plates can only block larger impurities in the water. Hardness ions in the water will still form scale, which can cause pipe blockage and even damage the equipment. Furthermore, the filter components are easily clogged, which not only reduces the filtration effect and further decreases the efficiency of water electrolysis, but also reduces the lifespan of the device.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing purification and filtration mechanisms for hydrogen production and water electrolysis. Therefore, we propose a purification and filtration mechanism for hydrogen production and water electrolysis that can effectively solve the above problems. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: In this hydrogen production water electrolysis purification and filtration mechanism, when the electrolyzed water flows in through the inlet pipe on the treatment tank, the softener and electrolyzed water are automatically mixed, effectively removing calcium and magnesium ions from the water. This prevents blockage problems caused by scale formation in the hydrogen production equipment from the source, extending the equipment's service life. The conveying cylinder replenishes the softener from the softener cylinder through a one-way valve at the input end, improving the overall water electrolysis efficiency. The specific details are as follows:

[0017] (1) By using the impact of water flow on the first water wheel to drive the magnetic block, the softener and electrolyzed water are automatically mixed. This can efficiently remove calcium and magnesium ions from the water, avoid scale blockage in the hydrogen production equipment from the source, and automatically adjust the amount of softener added according to the fluctuation of water pressure. No manual intervention is required, which saves labor costs, ensures a continuous and stable softening effect, extends the service life of the equipment, and indirectly improves the overall treatment efficiency of electrolyzed water.

[0018] (2) The water flow in the transmission pipeline impacts the second water wheel, and the cleaning ring moves up and down along the filter element through mechanical transmission. The cleaning is completed by using the kinetic energy of the water flow itself, without the need for additional power, reducing energy consumption, removing impurities on the surface of the filter element in time, avoiding pore blockage, solving the problem of efficiency decline caused by manual disassembly of multi-layer filter plates, and ensuring long-term stable filtration efficiency.

[0019] (3) After the cleaning ring triggers the circuit, the valve closes to prevent interference from the new water flow. The second water pump drives the clean water to backwash the inside of the filter element. The gas-liquid mixed flow enhances the rinsing force and can specifically remove deep and stubborn impurities. Compared with simple water rinsing, it is more thorough, ensuring that the filter element works continuously and efficiently, and improving the backwashing effect and efficiency.

[0020] (4) The piston squeezes the air bladder to allow gas to enter the filter cartridge, mixes with the electrolyzed water to increase water flow disturbance, and makes it easier for impurities in the water to be captured by the filter element, significantly improving filtration efficiency. Gas replenishment is convenient and can be achieved by piston movement without the need for complicated devices, thus optimizing the dynamic effect of the filtration process.

[0021] (5) The airbag is fed through the first pipe with the waste heat from the water electrolysis process recovered by the heat recovery system to preheat the water electrolysis, realize the heat recycling, reduce energy waste, improve the overall energy utilization efficiency of the system, conform to the environmental protection concept of energy conservation and consumption reduction, and reduce the energy cost of the hydrogen production process.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: In this example, the automatic mixing of the softener and electrolyzed water effectively removes calcium and magnesium ions from the water, preventing clogging of the hydrogen production equipment due to scale buildup from the source. Figures 1-5 , Figure 12 and Figure 13The technical solution shown includes a treatment tank 1, with an inlet pipe 2 for conveying electrolyzed water connected through it. The bottom end of the inlet pipe 2 is connected to a conveying pipe 3 via a flange. The conveying pipe 3 is located inside the treatment tank 1, and its bottom end is connected to a transmission pipe 4 via a flange. A softening treatment assembly is installed inside the treatment tank 1, including a conveying cylinder 5 installed inside the treatment tank 1. The conveying cylinder 5 is located on the side of the conveying pipe 3. An inclined hole 6 is formed through the inner wall of the conveying pipe 3 connecting to the conveying cylinder 5. The input end of the conveying cylinder 5 is connected to a softening agent cylinder via a pipe, and the output end of the conveying cylinder 5 is connected to the inclined hole 6. Both the input and output ends of the conveying cylinder 5 are equipped with one-way valves. A suitable valve is connected through the inside of the conveying cylinder 5. A piston 7 is connected to a first magnetic block 8 at the outer end of the conveying cylinder 5. A first spring 9 is sleeved on the outer side of the piston 7. A first water wheel 10 is installed inside the liquid inlet pipe 2. A first rotating shaft 11 is connected through the first water wheel 10. The first rotating shaft 11 extends through to the outer side of the liquid inlet pipe 2. An electric structure 12 is sleeved on the outer side of the first rotating shaft 11. The electric structure 12 includes an inner rotating cylinder 1201 sleeved on the outer side of the first rotating shaft 11. A transmission cylinder 1203 is connected to the outer side of the inner rotating cylinder 1201 through a pipe. A movable plate 1204 adapted to it is provided in the inner cavity of the transmission cylinder 1203. An outer rotating cylinder 1202 is sleeved on the outer side of the inner rotating cylinder 1201. A storage cavity is opened inside the first rotating shaft 11, and an outer release ring 1207 and a second release ring 1202 are installed inside the storage cavity. Spring 1206 and the inner cavity of the transmission cylinder 1203 are connected to the inner cavity of the storage chamber. An inner contact ring 1205 is connected to the end of the second spring 1206. An electric slip ring 1208 is sleeved on the outer side of the first rotating shaft 11. An outer release ring 1207 is connected to the electric slip ring 1208 via a wire. A second magnetic block 14 is installed inside the processing tank 1, located on the side of the first magnetic block 8. The electric slip ring 1208 is connected to the second magnetic block 14 via a wire 13. When electrolyzed water flows in through the inlet pipe 2 on the processing tank 1, it impacts the first water wheel 10, causing it to rotate and drive the first rotating shaft 11 to rotate. The energized structure 12 on the outer side of the first rotating shaft 11 supplies power to the second magnetic block 14 via the wire 13, causing it to become magnetic. The first rotating shaft 11 then drives the outer inner rotating cylinder 1201 to rotate, making... The movable plate 1204 inside the outer rotating cylinder 1202 moves outward from the transmission cylinder 1203 under centrifugal force. This outward movement of the movable plate 1204 generates suction within the transmission cylinder 1203. Since the transmission cylinder 1203 is connected to the storage cavity inside the first rotating shaft 11 via a pipe, the suction is transmitted to the storage cavity through the pipe. The change in air pressure within the storage cavity overcomes the elastic force of the second spring 1206, pulling the inner contact ring 1205 to move until it contacts the outer release ring 1207, forming a conductive path. Current flows from the power source through the inner contact ring 1205, the outer release ring 1207, and the circuit to the slip ring 1208. The slip ring 1208 then transmits the current to the second magnetic block 14 via the wire 13, facilitating subsequent operations.When the rotational speed of the first rotating shaft 11 decreases, the centrifugal force on the moving plate 1204 decreases, and it moves towards the first rotating shaft 11 under the action of air pressure. At this time, the air pressure in the placement cavity is restored, and the second spring 1206 pushes the inner contact ring 1205 to separate from the outer release ring 1207, the circuit is broken, and the magnetic field of the second magnetic block 14 disappears. The whole device is not only convenient to be driven by a water wheel, but also has low friction when the inner contact ring 1205 and the outer release ring 1207 are in contact, which improves the service life of the device. Since the second magnetic block 14 and the first magnetic block 8 repel each other due to their like poles, they push the piston 7 to move into the conveying cylinder 5, compressing the first spring 9. At this time, the softener in the conveying cylinder 5 enters the inclined hole 6 through the one-way valve, and The water is injected into the delivery pipe 3 through the inclined hole 6, thus achieving automatic mixing of the softener and electrolyzed water. This effectively removes calcium and magnesium ions from the water, preventing blockages in the hydrogen production equipment due to scale buildup, extending the equipment's lifespan. Furthermore, when the water pressure fluctuates, the rotational speed of the first water wheel 10 changes, the magnetism of the second magnetic block 14 weakens, the first spring 9 resets, pushing the piston 7 back, increasing the distance between the first magnetic block 8 and the second magnetic block 14. The delivery cylinder 5 replenishes softener from the softener cylinder through the one-way valve at the input end, completing the cycle. The automatic adjustment of the softener addition ensures stable softening effects, eliminating the need for frequent manual operation, saving labor costs, and improving overall water electrolysis efficiency.

[0038] Example 2: In this example, the cleaning ring 24 moves up and down along the guide rod 25 to clean the impurities attached to the outside of the filter element 18. The cleaning ring 24 is driven by the kinetic energy of the water flow itself, eliminating the need for an additional power source and reducing equipment energy consumption. Simultaneously, it promptly removes impurities from the surface of the filter element 18, preventing blockage of the filter element 18 pores and ensuring long-term stability of filtration efficiency. Specifically, as follows... Figure 1 and Figures 6-10As shown, the following is disclosed: A first water pump 15 is installed on the side of the treatment tank 1. The first water pump 15 is installed on the transmission pipe 4. A valve 16 is installed on the transmission pipe 4. A filter cartridge 17 is installed on the side of the treatment tank 1. The end of the transmission pipe 4 is connected to the inside of the filter cartridge 17. A filter element 18 is installed inside the filter cartridge 17. An outlet pipe 19 is installed at the bottom of the filter element 18 and extends to the outside of the filter cartridge 17. A drive assembly is installed inside the transmission pipe 4. The drive assembly includes a second water wheel 20 installed inside the transmission pipe 4. A second rotating shaft 21 is connected to the inside of the second water wheel 20 and extends to the outside of the transmission pipe 4. A threaded rod 23 is connected to the end of the second rotating shaft 21 through a bevel gear structure 22. The threaded rod 23 extends to the inside of the filter cartridge 17. A cleaning ring 24 is sleeved on the outside of the threaded rod 23. A guide rod 25 is installed inside the filter cartridge 17 and is connected to the inside of the cleaning ring 24. Softened water flows into the transmission pipe 4 and... Opening valve 16 and the first water pump 15 facilitates the delivery of softened water to the filter cartridge 17. After the electrolyzed water passes through the filter element 18 to filter impurities, it is output from the outlet pipe 19. The filter element 18 can effectively trap impurities in the water, improve the purity of the electrolyzed water, provide high-quality raw materials for the subsequent hydrogen production process, and ensure hydrogen production efficiency and hydrogen purity. When the electrolyzed water is transported inside the transmission pipe 4, the water flow impacts the second water wheel 20 inside the transmission pipe 4 to rotate, driving the second rotating shaft 21 to rotate. The second rotating shaft 21 drives the threaded rod 23 to rotate through the bevel gear structure 22. When the threaded rod 23 rotates, the cleaning ring 24 moves up and down along the guide rod 25 to clean the impurities attached to the outside of the filter element 18. The cleaning ring 24 is driven by the kinetic energy of the water flow itself, eliminating the need for an additional power source, reducing equipment energy consumption, and timely removing impurities from the surface of the filter element 18 to prevent clogging of the filter element 18 pores, ensuring long-term stability of filtration efficiency and reducing the problem of reduced overall filtration efficiency caused by the need to manually disassemble multiple filter plates.

[0039] Example 3: In this example, water is sprayed in reverse through the through-hole 30 on the outside of the cleaning pipe 29 into the filter element 18 to flush away impurities in the pores of the filter element 18. The reverse water spraying can specifically flush away impurities clogging the inside of the filter element 18, improving the thoroughness of cleaning. Specifically, as follows... Figures 2-8 , Figure 10 and Figure 11As shown, the following is disclosed: a contact plate 26 is installed at the bottom of the cleaning ring 24; a contact seat 27 is provided inside the filter cartridge 17, and the contact seat 27 is electrically connected to the valve 16; a backwashing assembly is installed on the filter cartridge 17, including a second water pump 28 installed on the filter cartridge 17, the second water pump 28 being electrically connected to the contact seat 27; the input end of the second water pump 28 is connected to external clean water through a pipe; the output end of the second water pump 28 is connected to a cleaning pipe 29, which extends through the filter cartridge 17 into the filter element 18; a through hole 30 is opened on the outside of the cleaning pipe 29; an air bladder 31 is installed inside the filter cartridge 17, located on the side of the piston 7; and the air bladder 31... The inlet of the airbag 31 is connected to the first pipe 32, and the outlet of the airbag 31 is connected to the second pipe 33. Both the first pipe 32 and the second pipe 33 are equipped with one-way valves. A sleeve 34 is connected to the end of the second pipe 33, and the sleeve 34 is fitted onto the outside of the cleaning pipe 29, communicating with the inner cavity of the cleaning pipe 29. When the cleaning ring 24 moves down to the bottom, the contact piece 26 contacts the contact seat 27, triggering the circuit. First, the valve 16 on the transmission pipe 4 is closed, stopping the transmission pipe 4 from supplying water to the filter cartridge 17, ensuring the subsequent backwashing effect. Then, the second water pump 28 is started, pumping clean water from outside into the cleaning pipe 29, which flows through the through-hole on the outside of the cleaning pipe 29. Water is sprayed in reverse direction into the filter element 18 to flush away impurities within its pores. This reverse spraying effectively removes clogged impurities, improving the thoroughness of the cleaning. Furthermore, as the piston 7 moves within the conveying cylinder 5, the air bladder 31 on its side is compressed. Gas inside the air bladder 31 is forced through the second pipe 33 into the sleeve 34, and then into the cleaning pipe 29. The gas mixes with clean water and is ejected from the through hole 30, forming a gas-liquid mixture that enhances the backwashing force and efficiency. Additionally, during piston 7 operation, gas can be forced into the cleaning pipe 29 for cleaning, facilitating the introduction of gas into the electrolyzed water inside the filter element 17. The gas moves upwards. The gas mixture facilitates mixing with the electrolyzed water, increasing the turbulence of the water flow and making it easier for impurities in the water to be captured by the filter element 18, thereby improving the overall filtration efficiency. Furthermore, the gas inlet 31 is supplied with gas through the first pipe 32. The gas can be heated through the first pipe 32, and the heated gas recovers a large amount of heat generated during the electrolysis process through the heat recovery system, which facilitates the preheating of the electrolyzed water, realizes the recycling of heat, reduces energy waste, and improves the overall energy utilization efficiency of the system. The wastewater after backwashing is discharged from the bottom of the filter cartridge 17. After cleaning, the second water pump 28 is turned off and the valve 16 is opened by the processor to restore normal filtration.
