[0002] Electrolysis of water to produce hydrogen is a process that uses electricity to decompose water into hydrogen and oxygen. By passing direct current through the water, water molecules are oxidized at the anode to produce oxygen, and reduced at the cathode to produce hydrogen. This process not only produces hydrogen efficiently but is also clean and pollution-free, making it an important renewable energy technology with wide applications in energy production and storage.

[0003] A search revealed an existing patent (publication number: CN221412686U) that discloses a hydrogen collection instrument for a water electrolysis hydrogen production device. The instrument includes a base plate, a suction assembly, and a flow assembly.

This patent utilizes a processing assembly to filter moisture from the hydrogen, enabling the use of a desiccant to filter moisture, thereby reducing costs. Furthermore, the processing assembly facilitates easy replacement of the desiccant.

[0004] However, in the process of producing hydrogen through water electrolysis, the efficiency of using a gas pump for filtration is relatively slow, which is not conducive to the rapid filtration of hydrogen.

Figure 1 As shown, the water electrolysis hydrogen generator includes: a mounting plate 1; a drying and filtering device 2 mounted on the mounting plate 1, which is used to dry hydrogen; an extraction device 3 mounted on the top of the mounting plate 1 and connected to the drying and filtering device 2, which is used to transfer the hydrogen filtered by the drying and filtering device 2; and a hydrogen storage device 4 mounted on the top of the mounting plate 1 and connected to the extraction device 3, which is used to store the hydrogen transferred by the extraction device 3 to ensure safety.

[0027] In this embodiment, the drying and filtering device 2 further includes: a turbine 205 fixedly installed inside the filter box 202, and an air outlet pipe 206 fixedly installed at the bottom of the filter box 202, with the outer surface of the air outlet pipe 206 fixedly sleeved on the mounting base 201.

[0028] Figure 3 A schematic diagram of the structure of the drying assembly 203 provided in an embodiment of the present invention is shown. Figure 3 As shown, in this embodiment, the drying component 203 includes: a filter housing 207 fixedly installed inside the filter box 202, a desiccant layer 208 fixedly installed inside the filter housing 207, a molecular sieve layer 209 fixedly installed on the top of the desiccant layer 208, and an activated alumina layer 210 fixedly installed on the top of the molecular sieve layer 209.

[0029] When using the water electrolysis hydrogen production device, hydrogen gas is first introduced into the drying and filtration device 2 through the inlet pipe 204. After entering the filter box 202, the hydrogen gas is accelerated by the turbine 205 and quickly passes through the drying assembly 203. In the drying assembly 203, the hydrogen gas sequentially passes through the activated alumina layer 210, the molecular sieve layer 209, and the desiccant layer 208. These layers adsorb moisture and impurities in the hydrogen gas, thereby achieving the drying and purification of the hydrogen gas. The treated hydrogen gas is discharged through the outlet pipe 206, completing the entire filtration process. The turbine 205 accelerates the filtration process, optimizing this operation.

[0030] Among them, the gas extraction device 3 can be a common gas pump, and the hydrogen storage device 4 can be an existing storage tank, etc.

[0031] By using the electrolytic water hydrogen collector provided in this embodiment, hydrogen gas passes sequentially through the active alumina layer, molecular sieve layer and desiccant layer in the drying component. These layers adsorb moisture and impurities in the hydrogen gas, thereby achieving the drying and purification of the hydrogen gas. After being accelerated by the turbine, the hydrogen gas passes through the drying component quickly and is then transported to the hydrogen storage device for storage by the pumping device.

[0032] Example 2

[0033] This utility model embodiment provides an electrolytic water hydrogen production collector, which improves the gas extraction device 3 based on embodiment one. Figure 4 A schematic diagram of the air extraction device provided in an embodiment of this utility model is shown. Figure 4As shown, the gas extraction device 3 includes: a pad 301 fixedly installed on the top of the mounting plate 1, a gas pump 303 fixedly installed on the top of the pad 301, a connecting pipe 302 connected to the outlet pipe 206 of the filter box 202 for receiving hydrogen gas output from the filter box 202, and an outlet pipe 304 fixedly installed on the top of the gas pump 303 for outputting hydrogen gas to the hydrogen storage device 4.

[0034] Example 3

[0035] This utility model embodiment provides an electrolytic water hydrogen production collector, which improves the hydrogen storage device 4 based on embodiment one or two. Figure 5 A schematic diagram of the hydrogen storage device 4 is shown. Figure 5 As shown, the hydrogen storage device 4 includes: a support plate 401 fixedly installed on the top of the mounting plate 1, a cooling box 402 fixedly installed on the top of the support plate 401, an inlet 403 and an outlet 404 fixedly installed on the top of the cooling box 402, and a gas storage tank 405 fixedly installed inside the cooling box 402.

[0036] In this embodiment, an inlet pipe 406 and an outlet pipe 407 are fixedly installed on the top of the gas storage tank 405. One end of the outlet pipe 304 of the extraction device 3 is fixedly connected to the inlet pipe 406 and is used to transfer hydrogen into the gas storage tank 405.

[0037] In this embodiment of the invention, the bottom of the filter housing 207 is provided with holes for outputting filtered hydrogen gas.

[0038] In the hydrogen production process via water electrolysis, hydrogen gas is first introduced through the outlet pipe 206 of the drying and filtering device 2, and then transported to the gas pump 303 in the extraction device 3 via the connecting pipe 302. The gas pump 303 further compresses the hydrogen gas and transports it to the hydrogen storage device 4 through the outlet pipe 304. Since the storage tank 405 is installed inside the cooling box 402, the coolant circulates through the inlet 403 and outlet 404 to reduce the temperature of the hydrogen gas, achieving low-temperature storage of hydrogen gas and ensuring its safe storage in the storage tank 405.

[0039] By employing the electrolytic water hydrogen collector provided in this embodiment, hydrogen gas sequentially passes through an activated alumina layer, a molecular sieve layer, and a desiccant layer in the drying assembly. These layers adsorb moisture and impurities from the hydrogen gas, thereby achieving hydrogen drying and purification. The hydrogen gas is then accelerated through the drying assembly by a turbine, increasing the hydrogen filtration speed of the drying assembly. Simultaneously, the dried hydrogen gas is pumped out by a vacuum device to a storage tank installed in a cooling chamber, achieving low-temperature storage of the hydrogen gas and ensuring its safe storage in the storage tank.
