Working principle of QYH-ESH electrolytic sodium hypochlorite generator
QYH® electrolytic sodium hypochlorite generator is a disinfectant production equipment, through which weak brine undergoes electrochemical reaction under the action of a DC electric field through electrolysis electrode and pure sodium hypochlorite liquid is produced under the catalytic action of ruthenium, iridium and other precious metal coatings of pure titanium electrode. Sodium hypochlorite solution is a strong oxidant, which has strong sterilizing and bleaching effect and is the most widely-used disinfectant currently.
Electrolysis principle of QYH-ESH electrolytic sodium hypochlorite generator
QYH® electrolytic sodium hypochlorite generator is a new equipment used for on-site preparation of sodium hypochlorite solution, which is suitable for all kinds of places where sodium hypochlorite is required for disinfection, sterilization and algae killing. Its working principle is: sodium chloride solution undergoes a series of electrochemical reactions in the electrolytic cell under certain cell voltage and finally generates sodium hypochlorite solution, the generation process of sodium hypochlorite can be expressed by the chemical equation as follows:
Solution reaction: 2NaOH+Cl2→NaCl+NaClO+H2O
Sterilization principle of sodium hypochlorite solution
Sodium hypochlorite is used for disinfection mainly in such a way that hypochlorous acid is generated by hydrolysis and then is further decomposed to generate nascent oxygen, and strong oxidizing property of nascent oxygen results in denaturation of protein and other substances on the bacteria and viruses, thus killing pathogenic microbes. Secondly, hypochlorous acid not only acts on cell wall and virus shell during sterilization and killing of virus, but also can penetrate into bacteria (virus) since sodium hypochlorite has small molecules and is not electrically charged to generate oxidizing reaction with organic polymers such as bacterial (viral) proteins, nucleic acid and enzymes, thus killing pathogenic microbes. Thirdly, chloride ions produced by hypochlorous acid can also significantly change the osmotic pressure of bacteria and virions, resulting in cell death due to loss of viability.
