In industry, caustic soda, chlorine and hydrogen are mainly produced by electrolyzing salt water solutions.
Under the conditions of the electrolyte, 2NaCl+2H2O= 2NaOH+H 2 ↑+ Cl 2 ↑
At the same time, H2 and CL2 will produce a large amount of by-gas HCL, which is used to make dyes, spices, drugs, various chlorides and corrosion inhibitors. H2 is colorless and odorless, and is flammable and explosive. It can burn when the volume fraction in the air is 4% to 75%.
Liquid chlorine, that is, liquid chlorine, is a yellow-green toxic liquid with strong irritation and corrosiveness. Liquid chlorine is unstable. It is a volatile substance that is liquid at room temperature. During transportation, it is put into a cylinder under high pressure to become liquid. If the seal is not tight, the liquid chlorine may become gaseous, which will increase the pressure inside the cylinder and cause the cylinder to explode. Chlorine is highly toxic, and the chlorine spread by the explosion is harmful to the environment and the human body. Chlorine exceeding a certain concentration can cause severe poisoning when inhaled by the human body. Therefore, it is particularly important to detect the leakage of H2, CL2 and HCL gases in the production workshop.
The H2 gas detector produced by our company has explosion-proof function, waterproof and dust proof level reaches IP65, and has obtained CE, ATEX certification. The hydrogen detector can detect trace H2 leakage with a detection range of 0-1000ppm, or 0-100%LEL (0-4%vol), effectively detecting gas leakage on site and avoiding explosion. The CL2 gas detector uses an electrochemical sensor with high sensitivity, a detection range of 0-20ppm, and a resolution of 0.1ppm. When the concentration in the air reaches 2ppm, an alarm will be triggered and external devices such as fans, solenoid valves, etc. will be linked through switch output to effectively avoid danger.
