[0002] A proton exchange membrane electrolyzer (PEM electrolyzer) is a device that uses pure water as raw material to produce hydrogen or oxygen by electrolyzing water. The anode output of the PEM electrolyzer is mainly a mixture of oxygen and water, and the cathode output is mainly a mixture of hydrogen and water. The electrolyzer supporting system needs to perform preliminary separation of oxygen and water on the anode side and hydrogen and water on the cathode side. However, after separation, the storage stage requires replacement of containers, and the device needs to be shut down during the container replacement process.

[0003] For example, application number CN202411415119.5 discloses a hydrogen separation system and process for a PEM electrolyzer, which relates to the field of electrolyzer technology. The system includes a PEM electrolyzer, which is connected to a gas-liquid separator, which is respectively connected to a cooler and a water seal tank, and the cooler is also connected to a water seal tank. A condensate tank is provided on the pipeline connecting the cooler and the water seal tank, and the water seal tank is respectively connected to a water injection tank, a nitrogen tank and a U-shaped overflow liquid discharge pipe; a first regulating valve is provided on the pipeline connecting the gas-liquid separator and the water seal tank; a liquid level gauge is provided on the gas-liquid separator, the liquid level gauge is connected to a liquid level controller, and the liquid level controller is connected to the first regulating valve. The utility model realizes the functions of preliminary separation of hydrogen and water, hydrogen cooling, flash evaporation, water seal, nitrogen humidification, and nitrogen replacement; the valve adopts a pneumatic or electric valve, which can be automatically operated by program control, reflecting ease of operation; the water seal tank in the system integrates multiple process functions such as flash evaporation, water seal, drainage, and nitrogen humidification, which can reduce pipelines and equipment and reduce system costs.

[0004] Although this patent realizes the functions of preliminary separation of hydrogen and water, hydrogen cooling, flash evaporation, water sealing, nitrogen humidification, and nitrogen replacement; the valve adopts pneumatic or electric valves, which can be automatically operated by electric control, reflecting the ease of operation; the water seal tank in the system integrates multiple process functions such as flash evaporation, water sealing, drainage, and nitrogen humidification, which can reduce pipelines and equipment and reduce system costs.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The utility model adopts PEM technology and realizes efficient separation of hydrogen and oxygen through a unique device design. The electrolytic cell in the device can effectively electrolyze the pure water in the water tank into hydrogen and oxygen. After the hydrogen is generated, it is dehydrated by the hydrogen-water separator, dried by the color-changing silica gel drying tube, and purified by the molecular sieve tube. This orderly processing flow greatly improves the purity and dryness of the hydrogen, meeting the application requirements for high-quality hydrogen. At the same time, the constant temperature rack generates a temperature of 70℃±10℃ during the hydrogen treatment process, which not only helps to reduce heat loss, but also improves the electrolysis efficiency, and avoids the adverse effects of excessive temperature on the stability and durability of the equipment, thereby improving the operating efficiency and performance of the hydrogen and oxygen separation device as a whole.

[0018] 2. The design of the oxygen temporary storage tank and the hydrogen temporary storage tank is a highlight of the utility model. During the hydrogen and oxygen separation process, due to the quantitative nature of traditional oxygen and hydrogen collection containers, they need to be shut down and replaced after reaching the reserve value, resulting in time waste and reduced efficiency. The oxygen temporary storage tank and the hydrogen temporary storage tank in the utility model can continuously temporarily store the oxygen and hydrogen generated during the hydrogen and oxygen separation process. Taking oxygen as an example, the oxygen temporary storage tank can continue to collect oxygen when the oxygen collection tank reaches the reserve value and needs to be replaced, avoiding the situation where the entire device needs to be shut down due to oxygen recovery and storage, ensuring the continuity of the hydrogen and oxygen separation process, and significantly improving production efficiency.

Similarly, the similar design between the hydrogen limiting tube and the hydrogen collecting tank also ensures the sealing of hydrogen during the collection and storage process, prevents hydrogen leakage, and improves the safety and stability of the device.

[0044] Among them, a conical groove is provided at the internal rear end position of the hydrogen collecting tank 304, and an elastically stretchable hydrogen conical plug 342 is fixedly installed at the internal rear end position of the hydrogen collecting tank 304.

[0045] During use, first, pure water is injected into the water tank body 102 through the water supply pipe provided at the bottom, and the pure water capacity inside the water tank body 102 is checked in conjunction with the water tank pressure gauge 121. When it is necessary to separate the pure water into hydrogen and oxygen, the electrolytic cell 103 is connected to the pipe of the water tank body 102, and the pure water inside the water tank body 102 is transported to the electrolytic cell 103. The electrolytic cell 103 is started by the console at the front end of the device controller 1. A DC power supply is provided inside the corresponding electrolytic cell 103. The electrolytic cell 103 electrolyzes the pure water to produce hydrogen and oxygen. The hydrogen is transported to the hydrogen-water separator 106 by the hydrogen pipeline 105, and the oxygen is transported to the oxygen temporary storage tank 201 by the oxygen pipeline 104.

[0046] After the hydrogen is transported from the hydrogen pipeline 105 to the hydrogen-water separator 106, it is dehydrated and then transferred from the hydrogen-water separator 106 to the color-changing silica gel drying tube 108 for drying and the molecular sieve tube 109 for purification.

[0047] Example 2

[0048] On the basis of Example 1, during the process of hydrogen and oxygen separation, the oxygen collection container is quantitative. Therefore, when the container reaches the reserve value, it will not be able to store gas further and needs to be shut down for replacement, which will waste time and reduce efficiency. In order to solve the above problems, the above embodiment has been further improved.

[0049] After oxygen is transported by the oxygen pipeline 104 and stored in the oxygen temporary storage tank 201, the oxygen limiting tube 203 is installed and docked with the oxygen collecting tank 204. After the oxygen limiting tube 203 and the oxygen collecting tank 204 are plugged in, the oxygen limiting plug 231 and the oxygen conical plug 242 fit and shrink, and the oxygen limiting tube 203 and the interior of the oxygen collecting tank 204 are connected. At this time, the oxygen valve 202 is opened, and the oxygen in the oxygen temporary storage tank 201 will enter the oxygen collecting tank 204 for collection and processing.

[0050] In summary, the design of the oxygen temporary storage tank 201 avoids the situation where the entire device needs to be shut down for oxygen recovery and storage after the separation of hydrogen and oxygen. During the process of hydrogen and oxygen separation, the oxygen temporary storage tank 201 can continue to temporarily store and collect the generated oxygen so that the oxygen collection tank 204 can be replaced. At the same time, after the oxygen limiting tube 203 is separated from the oxygen collection tank 204, the oxygen limiting plug 231 and the oxygen conical plug 242 will be reset respectively, synchronously limiting the delivery connection position of the oxygen temporary storage tank 201 and the oxygen collection tank 204 to avoid leakage.

[0051] Example 3

[0052] On the basis of the above embodiment, during the process of hydrogen and oxygen separation, the hydrogen collection container is quantitative. Therefore, when the container reaches the reserve value, it will not be able to store gas further and needs to be shut down for replacement, which will waste time and reduce efficiency. In order to solve the above problems, the above embodiment has been further improved.

[0053] The hydrogen purified by the molecular sieve tube 109 will be transported to the hydrogen temporary storage tank 301 by a pipeline, and the hydrogen limiting tube 303 and the hydrogen collecting tank 304 will be installed and docked. After the hydrogen limiting tube 303 and the hydrogen collecting tank 304 are plugged in, the hydrogen limiting plug 331 and the hydrogen conical plug 342 fit and shrink, and the hydrogen limiting tube 303 and the inside of the hydrogen collecting tank 304 are connected. At this time, the hydrogen valve 302 is opened, and the hydrogen in the hydrogen temporary storage tank 301 will enter the hydrogen collecting tank 304 for collection and treatment.

[0054] To sum up, the design of the hydrogen storage tank 301 avoids the situation where the entire device needs to be shut down for hydrogen recovery and storage after the separation of hydrogen and oxygen. During the process of hydrogen and oxygen separation, the hydrogen storage tank 301 can continuously temporarily store and collect the generated hydrogen so that the hydrogen collection tank 304 can be replaced. At the same time, after the hydrogen limiting tube 303 is separated from the hydrogen collection tank 304, the hydrogen limiting plug 331 and the hydrogen conical plug 342 will be reset respectively, synchronously limiting the delivery connection position of the hydrogen storage tank 301 and the hydrogen collection tank 304 to avoid leakage.
