Sodium Hypochlorite Generator
The sodium hypochlorite generator is a type of water treatment disinfection device which uses sodium chloride as a raw material to produce a sodium hypochlorite solution by electrolytic reaction.
Sodium hypochlorite is a strong oxidizing agent and disinfectant which occurs by electrolysis without a diaphragm by taking a dilute solution of a widely available industrial salt or seawater. To ensure that the sodium hypochlorite texture is fresh and has a high activity. To ensure the disinfection effect, the sodium hypochlorite generated will be added to the device while it is occurring. It has the same oxidative and disinfecting properties as chlorine and chlorine compounds.
working principle
1. The sodium hypochlorite generator is a combined form, which is metered into the electrolytic cell by dilute brine metering, and is electrolyzed by a silicon rectifier to generate sodium hypochlorite.
2. 1 kg of sodium hypochlorite salt consumption: 4.0-4.2; 4.3-4.5KW.
3. In the brine solution, there are several ions such as Na+ and H-. According to the theory of electrolysis, when the electrode is inserted, at a certain voltage, the electrolyte solution conducts electricity due to the movement of ions and the reaction of the electrode. At this time, CL-, Negative ions such as OH- move toward the anode, and positive ions such as Na+ and H+ move toward the cathode, and discharge occurs on the corresponding electrodes, thereby performing a redox reaction to produce a corresponding substance.
4. The brine solution electrolysis process can be expressed by the following reaction equation: NaCl=Na++Cl-
5. Anode electrolysis: H2O=H+OH- 2Cl-2e-→Cl2↑
Cathodic electrolysis: 2H-+2e-→H2↑
6. In the non-diaphragm electrolysis device, the electrolyte and the electrolyzed product are escaping outward in the solution, and the others are all in one electrolytic cell. Because the hydrogen acts to a certain agitation of the solution during the escape process, the two poles are made. A series of chemical reactions take place between the electrolyzed products, and the reaction equation is as follows:
2NaCl+2H2O→2NaOH+H2↑+Cl2
2NaOH+Cl2→NaClO+NaCl+H2O
7. In the absence of diaphragm electrolyzed brine, the total equation of the solution is the sum of the two reaction formulas listed above. NaCl+H2O+2F→NaClO+H2↑
8. The sodium hypochlorite generator consists of an electrolytic cell, a silicon rectifier electric control cabinet, a salt dissolution tank, a cooling system, and a supporting PUVC pipeline, a valve, a ejector, a flow meter, and the like.
Anode material selection
The anode material can be selected from coated titanium anode and mixed oxide coated titanium anode, and has a long service life. The overpotential of the coated anode is also relatively low, the chlorine current is high, and the energy saving effect is good. The titanium anode for the sodium hypochlorite generator is mostly made of platinum, rhodium alloy and titanium plated platinum anode.
