Hydrogen generator (lye)

Introduction

DCH type hydrogen generator produces hydrogen by electrolyzing potassium hydroxide aqueous solution. The instrument is equipped with a variety of intelligent control devices and is easy to use.

Working principle and process flow

The working principle of this instrument is the traditional diaphragm alkali electrolysis method. The conductive medium in the electrolytic cell is potassium hydroxide aqueous solution, and the separator between the two pole chambers is the diaphragm of the aerospace electrolysis equipment. After direct current is applied to the two poles, the water molecules immediately undergo an electrochemical reaction at the two poles of the electrolytic cell, producing oxygen at the anode and oxygen at the cathode. hydrogen.

The reaction formula is as follows:

Anode: 2OH–-2e → H2O +1/2O2↑

Cathode: 2H2O+2e → 2OH– +H2↑

Total reaction formula: 2H2O → 2 H2↑+ O2↑

This instrument implements automatic control of pressure control, over-pressure protection, flow display, flow tracking, etc., so that the output hydrogen can be fully automatically adjusted at constant pressure according to the amount of hydrogen used by the gas chromatograph (within the range of gas production)

 Environmental requirements

Hydrogen generators cannot be used in closed rooms!

The instrument should be placed near hydrogen equipment and placed stably.

Ambient temperature: 0 ~ 45℃

Humidity: ≦ 85%

The inner plug of the alkali storage tank is used to prevent residual alkali liquid from leaking out and corroding the surface of the instrument during transportation. When using the instrument, the user must remove the inner plug to facilitate the discharge of oxygen. Users should keep it properly for use during transportation again!
