Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 5 As shown, an electrolytic hydrogen generator includes a hydrogen generator body, which is composed of a hydrogen generator, an air compressor, a chiller, a pure water machine and a hydrogen compressor. A control cabinet 1 is arranged inside the hydrogen generator, a deaerator 2 is arranged inside the hydrogen generator, and the deaerator 2 is located on the top of the control cabinet 1. A hydrogen-oxygen separator 4 is arranged on the rear side of the hydrogen generator, a hydrogen-water separator 6 is arranged on the rear side of the hydrogen generator, and the hydrogen-water separator 6 is located on the right side of the hydrogen-oxygen separator 4. A hydrogen buffer tank 7 is arranged on the rear side of the hydrogen generator, and the hydrogen buffer tank 7 is located on the right side of the hydrogen-water separator 6. The hydrogen buffer tank 7 is located on the rear side of the alkali liquid cooler 3. An electrolytic cell 9 is arranged on the bottom side of the hydrogen generator.

[0026] refer to Figure 1 and Figure 4 A first dryer 8 is arranged on the left side inside the hydrogen production device, and the first dryer 8 is located on the top of the electrolyzer 9. A second dryer 10 is arranged on the rear side inside the hydrogen production device, and the second dryer 10 is located on the left side of the hydrogen-oxygen separator 4.

[0027] As a technical optimization solution of the present invention, by setting the first dryer 8 and the second dryer 10, moisture in the hydrogen can be removed, ensuring the dryness and purity of the hydrogen, improving the quality of the hydrogen, and meeting subsequent use requirements.

[0028] refer to Figure 1 and Figure 2 A alkali liquid cooler 3 is arranged inside the hydrogen production device, and the alkali liquid cooler 3 is located at the rear side of the deaerator 2.

[0029] As a technical optimization solution of the present invention, the alkali solution cooler 3 is provided to reduce the heat generated during the electrolysis process, prevent the alkali solution temperature in the electrolytic cell from being too high, and ensure that the electrolysis process is carried out stably.

[0030] refer to Figures 1 to 4 The internal components of the hydrogen production device are all arranged inside the splicing frame, and a plurality of supporting legs are arranged at the bottom of the splicing frame.

[0031] As a technical optimization solution of the present invention, by arranging the internal components of the hydrogen production device inside the splicing frame, the contact between the internal components of the hydrogen production device and the external air is greatly increased, thereby improving the heat dissipation effect of the hydrogen production device.

[0032] refer to Figure 1 and Figure 3 A water seal box 5 is provided at the bottom side of the hydrogen production device, and the water seal box 5 is located on the left side of the control cabinet 1.

[0033] As a technical optimization solution of the present invention, the water seal box 5 is provided to prevent hydrogen from leaking from the inside of the hydrogen generator to the external environment, while preventing external air from entering the inside of the hydrogen generator, thereby avoiding hydrogen and air from mixing to form an explosive mixture, and at the same time helping to stabilize the pressure fluctuations in the hydrogen generator and ensure the stability of the pressure in the system.

[0034] refer to Figures 1 to 4 , several pressure gauges are installed inside the hydrogen production device.

[0035] As a technical optimization solution of the present invention, through the setting of the pressure gauge, the pressure gauge displays the gas pressure of the electrolyzer 9 and the pipeline in real time during the hydrogen production process, ensuring that the pressure is within a safe and normal range, and preventing equipment damage or dangerous situations caused by overpressure, such as leakage, explosion, etc.

[0038] refer to Figures 1 to 5 The output pipe of the chiller is connected to the electrolyzer 9 and the remaining components of the hydrogen production device.

[0039] As a technical optimization solution of the present invention, by setting up a chiller, maintaining the electrolytic cell 9 at a suitable low temperature state can improve the electrolysis efficiency and avoid increasing power consumption and reducing the efficiency of the electrolysis process due to high temperature.

[0040] refer to Figure 5 , the output end of the air compressor is connected to the input end of the hydrogen compressor.

[0041] As a technical optimization solution of the present invention, the provision of an air compressor can provide pressure for the hydrogen compressor, thereby avoiding the problem of reduced compression effect due to insufficient pressure of the hydrogen compressor.

[0042] refer to Figure 1 and Figure 3 Both sides of the bottom of the electrolytic cell 9 are fixedly connected with square tubes, and the square tubes are fixedly connected to the splicing frame of the hydrogen production device.

[0043] As a technical optimization solution of the present invention, the arrangement of the square tube makes the electrolytic cell 9 more stably fixed, thus avoiding the situation where the electrolytic cell is not fixed firmly enough, resulting in the electrodes no longer being correctly aligned, affecting the flow of current and the electrolysis efficiency.

[0044] The present invention first connects the control cabinet 1 to the external power supply, and the control cabinet 1 automatically controls and sets the system pressure, temperature, liquid level, purification switching time, etc., and various operating parameters are automatically monitored and controlled, and then the external water source is connected to the pure water machine. After the water source is connected from the outside, it enters the pure water machine for filtration and purification, and then enters the pure water tank, and then enters the electrolyzer 9 from the pure water tank. After electrolysis of water, hydrogen and oxygen are generated, and enter the hydrogen-oxygen separator 4 to output hydrogen and oxygen respectively. Oxygen is directly discharged outdoors, and hydrogen enters the deaerator 2 for secondary purification and then enters the hydrogen-water separator 6, and finally enters the first dryer 8 and the second dryer 10 for treatment and then enters the hydrogen compressor for compression, which can be stored in the hydrogen storage tank or output to the gas consumption node for supply.
