[0022] The hydrogen separation device includes a hydrogen separator V601, a hydrogen separation scrubber V610, a hydrogen cooler E603, and a hydrogen-water separator V603. One inlet end of the hydrogen separator V601 is connected to one outlet end of the electrolytic cell R601. One outlet end of the hydrogen separator V601 is connected to one inlet end of the hydrogen separation scrubber V610. One outlet end of the hydrogen separation scrubber V610 is connected to one inlet end of the hydrogen cooler E603. One outlet end of the hydrogen cooler E603 is connected to one inlet end of the hydrogen-water separator V603.

[0023] Furthermore, the oxygen separation device includes an oxygen drainer V606, an inlet end of which is connected to an outlet end of the oxygen-water separator V605, a first control valve is provided between the oxygen drainer V606 and the oxygen-water separator V605, and a second control valve is provided at an outlet end of the oxygen drainer V606.

[0024] Furthermore, the hydrogen separation device includes a hydrogen drainer V604, an inlet end of which is connected to an outlet end of the hydrogen-water separator V603, a third control valve is provided between the hydrogen drainer V604 and the hydrogen-water separator V603, and a fourth control valve is provided at an outlet end of the hydrogen drainer V604.

[0025] Furthermore, one inlet end of the oxygen separator scrubber V611 and one inlet end of the hydrogen separator scrubber V610 are both connected to the boundary nitrogen gas, one outlet end of the oxygen separator scrubber is connected to one inlet end of the oxygen separator V602, one outlet end of the hydrogen separator scrubber V610 is connected to one inlet end of the hydrogen separator V601, and one outlet end of the oxygen separator V602 and one outlet end of the hydrogen separator V601 are both connected to the outside.

[0026] Furthermore, one inlet end of the oxygen cooler E604 and one inlet end of the hydrogen cooler E603 are both connected to one outlet end of the water storage tank P101, one outlet end of the oxygen cooler E604 and one outlet end of the hydrogen cooler E603 are both connected to one inlet end of the water storage tank, and one inlet end of the electrolytic cell R601 is connected to one outlet end of the water storage tank P101.

[0027] Working Principle: The water storage tank P101 is used to release water into the electrolytic cell R601. The transformer B601, in conjunction with the hydrogen power supply E601, electrolyzes water in the electrolytic cell R601. The oxygen mixture and hydrogen mixture produced by water electrolysis are respectively sent to the oxygen separator V602 and the hydrogen separator V601. The oxygen separator V602 separates oxygen from the oxygen mixture and sends it to the oxygen separator scrubber V611 for washing. After condensation treatment by the oxygen cooler E604, the water vapor in the oxygen is condensed, and the purified oxygen enters the oxygen-water separator V605. The oxygen-water separator V605 can store and utilize oxygen. The water present in the oxygen-water separator V605 settles at the bottom of the oxygen-water separator V605 and is discharged into the oxygen drainer V606 through the first control valve. The water in the oxygen drainer V606 can be discharged through the second control valve, preventing the random release of oxygen. Similarly, the hydrogen mixture is processed sequentially through the hydrogen separator V601, the cleaning and washing device, and the hydrogen cooler E603, and stored in the hydrogen-water separator V603. The water at the bottom of the hydrogen-water separator V603 is discharged into the hydrogen drainer V604 through the third control valve, and the water in the hydrogen drainer V604 is discharged through the fourth control valve.

[0028] In addition, the boundary nitrogen can be used to expel air from the oxygen separator V611, the oxygen separator V602, the hydrogen separator V610, and the hydrogen separator V601, and discharge them outside the boundary. This reduces the influence of air on the extracted oxygen and hydrogen. Furthermore, by waterproofing the bottom of the oxygen separator V611 and the hydrogen separator V610, some impurities in the adsorbed oxygen and hydrogen are washed away.

[0029] It is worth mentioning that the technical features of the water storage tank P101 and the boundary nitrogen involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be adopted by conventional choices in the field, and should not be regarded as the utility model point of this utility model patent. This utility model patent will not be further elaborated in detail.
