Water electrolysis hydrogen producing process by cooling filtering method

Abstract

The invention belongs to a water electrolysis hydrogen producing process, and relates to a water electrolysis hydrogen producing process by a cooling filtering method. The current hydrogen producing process has the defects that the H2 and O2 mixed gas can form reverse reaction easily under a suitable condition, the gas yield is reduced, the adjustability of gas is poor, and the use safety is low. In the process of the invention, the hydrogen and oxygen electrolyzed in an electrolytic bath (2) respectively enter a primary gas-water separator (3) and a primary gas-water separator (4) through respective pipes, and then enter a cooler (5), a secondary gas-water separator (6) and a secondary gas-water separator (7) for carrying out gas-water separation again; the hydrogen enters a washer (10); electrolyte separated at the lower part of the secondary gas-water separator enters an electrolyte storage tank (1); and a replenishment pump (9) pressurizes and replenishes the electrolyte in the storage tank (1) into the system. The invention has the advantages that the reversible reaction of gas is avoided, the gas production rate and the gas production efficiency are greatly improved, the gas can be conveniently adjusted in use, no auxiliary materials need to be added when the gas is used, the safety is improved, and the use cost is reduced.

Description

technical field [0001] The invention belongs to a process for producing hydrogen by electrolyzing water, in particular to a process for producing hydrogen by cooling and filtering water electrolysis.

[0003] In the existing hydrogen-oxygen machine process, the mixed gas of hydrogen and oxygen electrolyzed by the electrolyzer enters the corresponding gas-water separator and cooler. When using it, auxiliary ma...

AI Technical Summary

Problems solved by technology

When using it, auxiliary materials such as gasoline and gas are added as combustion aids. The disadvantages of this hydrogen production process are:

[0005] 2. The hydrogen and oxygen gas produced by the electrolyzer is strictly produced in a ratio of 2:1, and the gas adjustment ability is poor

[0006] 3. In order to adjust the hydrogen-oxygen flame, add additives such as gasoline, resulting in reduced safety

[0007] 4. The power loss of electrolysis is greatly increased; the operating cost is increased
