Embodiment Construction

[0023] Such as figure 1 As shown, in the gas balance device 20 for water electrolysis hydrogen production of the present invention, a hollow cavity is divided into two gas cavities by a membrane sheet 1, wherein one is a hydrogen gas cavity with a hydrogen gas outlet 4 and a hydrogen gas inlet 8 6. The other is an oxygen chamber 7 with an oxygen outlet 5 and an oxygen inlet 9, and a boss 10 is provided on the inner wall of the oxygen chamber 7. The channel of the oxygen outlet 5 runs through the boss 10 on the inner wall of the oxygen chamber 7 . The hollow cavity is formed by two semi-cavities with a "U" shape in section and symmetrically bolted through the membrane sheet 1 . The film sheet 1 is circular in the hollow cavity.

[0024] The hydrogen and oxygen gases produced by the equipment are passed through the steam-water separator, cooled, washed and condensed, and then passed into the gas adjustable balance device 20. When the unbalanced hydrogen and oxygen gases enter ...

Abstract

The invention relates to a gas equilibrium device for producing hydrogen through water electrolysis. The device comprises a hollow cavity, wherein the hollow cavity is separated into two gas cavities by a film; one gas cavity is a hydrogen cavity with a hydrogen outlet and a hydrogen inlet and the other gas cavity is an oxygen cavity with an oxygen outlet and an oxygen inlet; a boss is arranged on the inner wall of the oxygen cavity; the channel of the oxygen outlet penetrates through the boss on the inner wall of the oxygen cavity; the hollow cavity is formed by symmetrically bolting two half cavities with U-shaped profiles with the film; and the film is round in the hollow cavity. The gas equilibrium device has the following beneficial effects: by using the gas adjustable equilibrium device with simple inner structure, the pressure equilibrium effect is obvious; the pressure equilibrium speed is improved after the equipment is started and the hydrogen production time is correspondingly shortened; the operation reliability is enhanced; and the equipment manufacturing cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a gas balance device for producing hydrogen by electrolysis of water. Background technique [0002] In the process of hydrogen production by water electrolysis, if the pressure of the electrolyzer changes greatly, it will cause the interpenetration of hydrogen and oxygen, which directly affects the purity of hydrogen production. Therefore, the hydrogen-oxygen side pressure in the tank must be adjusted at any time during the hydrogen production process. Electrolyzers operating at normal pressure generally rely on gas storage tanks, steam-water separators, and scrubbers to adjust the pressure. However, during pressure operation, a pair of pressure regulators (one for hydrogen pressure regulator and the other for oxygen pressure regulator) must be installed in the system to adjust the pressure of the gas in the gas storage tank to ensure that the gas storage t...
