Description

Technical Field

[0001] The utility model relates to the technical field of water electrolysis hydrogen production, in particular to water electrolysis hydrogen production equipment with convenient electrode replacement. Background Art

[0002] Hydrogen is a substance that exists in gaseous form under standard conditions of hydrogen element. Its chemical formula is H2, which is composed of two hydrogen atoms and is also called molecular hydrogen. Hydrogen can release a large amount of heat when burned in oxygen. The temperature of its flame, the hydrogen-oxygen flame, reaches 3000℃, which can be used to weld or cut metals. Liquid hydrogen can be used as a high-energy fuel for rockets or missiles. Hydrogen can also be used to smelt important metals such as tungsten and molybdenum. Moreover, the product of hydrogen burning in oxygen is pure and pollution-free water. As a fuel, it has the characteristics of high combustion heat and low pollution. At the same time, hydrogen has a low density and can be used to fill balloons. Therefore, hydrogen has a wide range of uses. Methods for preparing hydrogen include preparing hydrogen by electrolysis of water, preparing hydrogen by water gas method, preparing hydrogen by synthesis gas and natural gas from thermal cracking of petroleum, preparing hydrogen by freezing coke oven gas, preparing hydrogen by reaction of iron with water vapor, etc.

When the anode electrode plate and the cathode electrode plate in the water electrolysis hydrogen production device need to be disassembled for maintenance or replacement, it is very cumbersome and inconvenient. At the same time, the subsequent installation is also cumbersome and inconvenient, and the efficiency is low. Utility Model Content

[0038] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0040] First, the cathode and anode electrode plates 23 and the diaphragm 22 are placed at the bottom of the fixing seat 1 21. The cathode and anode electrode plates 23 are a cathode electrode plate and an anode electrode plate. The diaphragm 22 has a mounting frame. The cathode and anode electrode plates 23 and the diaphragm 22 are inserted into the slots 26 of the fixing seat 1 21 and the fixing seat 2 24.

The structure is simple and firm, and it is easy to disassemble. The mounting frame of the diaphragm 22 is made of insulating material. No power is required, and then the installed cathode and anode electrode plates 23 and the fixing seat 21 are placed in the groove 13 at the top of the box body 11. In the process of electrolyzing water by powering the cathode and anode electrode plates 23, the generated gas is discharged from the gas outlet 12, and then the hydrogen is purified by the gas purification device. When the electrode needs to be replaced, the fixing seat 21 and the cathode and anode electrode plates 23 are directly pulled out, and the bolts on the fixing block 14 can be unscrewed to replace the electrode plate. The surfaces of the fixing seat 21 and the fixing block 25 are both provided with an insulating layer.

[0041] In some embodiments, a sealing gasket 131 is provided between the fixing seat 1 21 and the groove 13.
