Problems solved by technology

When the concentration of lye drops to a certain value, alkali must be added to the system, otherwise the electrolysis power consumption per unit of gas production will increase
The loss of alkali is not only a waste of resources, but also affects gas quality, purification treatment and analytical instruments

Embodiment Construction

[0009] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings of the embodiments, so as to make the technical solution of the present invention easier to understand and grasp.

[0010] Such as figure 1 As shown, the hydrogen-oxygen scrubber for water electrolysis hydrogen production is installed between the separator and the gas cooler. In particular, the main body of the hydrogen-oxygen scrubber is a washing cabin 3 filled with electrolytic raw water. 3. An air intake pipe 5 is pierced on the side wall. One end of the air intake pipe 5 is connected to the exhaust port of the separator, and the other end of the air intake pipe 5 extends below the liquid level of the electrolytic raw material water in the washing cabin 3; the washing cabin 3 The top is provided with an air outlet 6.

[0011] In order to facilitate the alkali replenishment of the separator, the side wall 3 of the washi...

Abstract

The invention provides an oxyhydrogen scrubber used in water electrolysis for hydrogen production. The oxyhydrogen scrubber is arranged between a separator and a gas cooler. In particular, the main body of the oxyhydrogen scrubber is a washing cabin containing electrolytic raw material water; a gas inlet pipeline penetrates and is connected with the sidewall of the washing cabin, one end of the gas inlet pipeline is connected with an exhaust port of the separator, and the other end of the gas inlet pipeline extends to and is located below the liquid level of the electrolytic raw material water in the washing cabin; the top of the washing cabin is provided with a gas outlet, and the sidewall of the washing cabin is provided with an overflow mouth communicated with the separator. With the oxyhydrogen scrubber provided by the invention, alkalinity of finished gas is effectively decreased, and recovery and reuse of alkali enables alkali loss and operation cost of equipment for hydrogen production through water electrolysis to be substantially reduced; moreover, gas temperature is decreased, burden on a subsequent gas cooler is reduced, and temperature and humidity of the final finished gas are further reduced.

Description

technical field [0001] The invention relates to a hydrogen-oxygen scrubber, in particular to a hydrogen-oxygen scrubber applied to hydrogen production by electrolysis of water. Background technique [0002] The normal operating temperature of the electrolytic cell in the water electrolysis hydrogen production equipment is about 85°C, and the generated hydrogen and oxygen enter the gas-liquid separator together with the electrolyte in the form of gas-liquid mixture. A large number of fine droplets produced when the bubbles burst form alkali mist, which is discharged with the separated hydrogen and oxygen, so the concentration of alkali solution will gradually decrease during the operation of the water electrolysis hydrogen production system. When the concentration of lye drops to a certain value, alkali must be added to the system, otherwise the electrolysis power consumption per unit of gas production will increase. The loss of alkali is not only a waste of resources, but a...
