Description

Technical Field

[0001] This invention relates to the field of hydrogen production component technology, specifically an integrated flow channel hydrogen production component. Background Technology

[0002] With the widespread application of miniaturized, portable water electrolysis hydrogen production equipment in civilian, laboratory, and small-scale hydrogen energy application scenarios, the industry has placed higher technical demands on the integration, sealing reliability, assembly efficiency, and space utilization of core hydrogen production components. Traditional bulk hydrogen production components can no longer meet the design and usage requirements of modern hydrogen production equipment. Firstly, the core components of existing small-scale water electrolysis hydrogen production equipment all adopt a separate, bulk structure. Functional units such as micro-pumps, resin filters, detection probes, electrolyzers, check valves, and high-pressure switches are independent of each other. These units can only be connected to each other via numerous external connectors and PE pipes. These external connection points are numerous and have poor sealing reliability, making them prone to water and gas leaks during long-term operation. Firstly, it disrupts the continuity of hydrogen production medium transmission, significantly reducing the operational safety and stability of the hydrogen production system. It cannot meet the core requirements of high sealing and high reliability for miniaturized hydrogen production equipment. Secondly, traditional bulk hydrogen production components have technical shortcomings such as low assembly efficiency, poor space utilization, and high maintenance difficulty. Split components require manual assembly one by one, which is cumbersome and has high labor and assembly costs, making it difficult to adapt to automated large-scale production. At the same time, the scattered components and messy external pipelines occupy a lot of space, which seriously restricts the development trend of miniaturized and portable hydrogen production equipment. Moreover, the disordered pipeline and component layout makes it extremely difficult to troubleshoot and replace components later, significantly reducing the operation and maintenance efficiency and ease of use of the equipment.

[0022] Working principle: The system uses the water circuit board 1 as the core integrated carrier. All functional components and prefabricated flow channels are integrated onto the water circuit board 1. The entire system uses the micro pump 4 as the core of water flow power, sequentially completing the entire process of pure water delivery, water purification, water quality testing, water electrolysis for hydrogen production, hydrogen-oxygen separation and discharge, and pressure safety protection. Pure water first enters the prefabricated inlet pipe 2 from the pure water inlet 3. The water flows along the prefabricated inlet pipe 2, passes through the pump inlet interface 5, and enters the input end of the micro pump 4. After being pressurized by the micro pump 4, the water is delivered... After being pumped, the water flows from the pump outlet 7 into the pre-filter pre-construction pipe 6. The water continues to flow along the pre-filter pre-construction pipe 6 to the pre-filter outlet 9, and then enters the resin filter element 8 to complete the water purification treatment. The purified water flows out from the resin filter element 8, flows through the post-filter outlet 11 into the post-filter pre-construction pipe 10, and flows through the detection probe 12 at the probe outlet 13 in the post-filter pre-construction pipe 10 to complete the real-time water quality detection. The purified water that meets the standards is continuously transported to the pre-electrolysis outlet 16. The water enters the electrolysis cell 14 through the electrolysis inlet 15 for water electrolysis. The oxygen generated by the electrolysis reaction is discharged from the oxygen outlet 17 at the bottom of the electrolysis cell 14, enters the oxygen discharge pre-fabricated pipe 18 through the oxygen discharge port 19, and finally exits the component from the oxygen outlet 20 along the oxygen discharge pre-fabricated pipe 18. The hydrogen generated by the electrolysis reaction is discharged from the electrolysis outlet 21 at the output end of the electrolysis cell 14, enters the connecting pre-fabricated pipe 22 through the hydrogen discharge port 23, and is transported along the connecting pre-fabricated pipe 22 to the valve input port 25 and enters the check valve 24. After the check valve 24 blocks the backflow, the hydrogen flows from the valve output port 27 into the hydrogen discharge pre-fabricated pipe 26. When the hydrogen is transported in the hydrogen discharge pre-fabricated pipe 26, the high-pressure switch 28 installed at the switch port 29 monitors the pipeline pressure in real time to ensure that the pipeline operating pressure is within a safe range. Finally, the hydrogen is stably discharged from the hydrogen outlet 30 along the hydrogen discharge pre-fabricated pipe 26, completing the entire process of water electrolysis hydrogen production and gas output.
