Introduction of sodium hypochlorite generator

Sodium hypochlorite generator is a device that generates sodium hypochlorite solution by electrolyzing dilute brine (with conditions that seawater is available). It is composed of electrolytic electrode assembly, rectifier power supply, automatic control system and other parts. The pure sodium hypochlorite solution is a strong oxidant. Strong bactericidal and bleaching effect, it is currently the most widely used disinfectant.

Principle of Sodium Hypochlorite

The main function of sodium hypochlorite disinfection is to form hypochlorous acid through its hydrolysis. Hypochlorous acid is further decomposed to form new ecological oxygen. The strong oxidizing property of new ecological oxygen denatures the bacteria and proteins on the virus, causing death. Pathogenic microorganisms. Secondly, in the process of sterilization and virus killing, hypochlorous acid can not only act on the cell wall and virus shell, but also because the hypochlorous acid molecule is small and has no charge, it can penetrate into the body of bacteria (viruses) and bacteria (viruses). Organic polymers such as proteins, nucleic acids, and enzymes undergo oxidation reactions, thereby killing pathogenic microorganisms. Thirdly, the chloride ion produced by hypochlorous acid can also significantly change the osmotic pressure of bacteria and virions, making cells inactivate and die.

The salt solution contains several ions such as Na + and H-. According to the theory of electrolysis, when the electrode is inserted, the electrolyte solution conducts electricity due to the movement of the ions and the electrode reaction at a certain voltage. At this time, CL-, OH- The negative ions move toward the anode, while the positive ions such as Na + and H + move toward the cathode, and a discharge occurs on the corresponding electrode, thereby carrying out a redox reaction and generating a corresponding substance. The electrolysis process of saline solution can be expressed by the following reaction equation:
NaCl = Na + + Cl-

Anodic electrolysis: H2O = H + OH-2Cl-2e— → Cl2 ↑ Cathodic electrolysis: 2H- + 2e— → H2 ↑ In a diaphragm-free electrolysis device, the electrolyte and the hydrogen produced by the electrolytic product escape from the solution In addition, the others are in an electrolytic cell. Because the hydrogen gas has a certain stirring effect on the solution during the expulsion process, a series of chemical reactions occur between the electrolytic products between the two electrodes.
