With competitive price and timely delivery, GIANT ANODE sincerely hope to be your supplier and partner.

1. Sodium hypochlorite generator is a combination of forms, through the measurement of dilute brine added to the electrolysis tank, through the silicon rectifier connected to the yin and yang direct current electrolysis to generate sodium hypochlorite.

2. 1 kg of sodium hypochlorite salt consumption: 4.0-4.2; 4.3-4.5 KW.

3. in brine solution contains Na+, H- and several other ions, in accordance with the theory of electrolysis, when inserted into the electricity, under a certain voltage, electrolyte solution due to the movement of ions and electrical reactions, conductive, then CL-, OH- and other negative ions to the Yang, while Na+, H+ and other positive ions to the anion to the negative, and in the corresponding electric discharge occurs, so as to carry out the redox reaction, the corresponding substances.

4. saline solution electrolysis process can be expressed in the following reaction equation: NaCl = Na + + Cl-

5. positive electrolysis: H2O = H + OH- 2Cl-2e- &#; Cl2&#; negative electrolysis: 2H- + 2e- &#; H2&#;

6. in the diaphragm electrolysis device, the electrolyte and electrolysis products of hydrogen in solution to the outside outside outside, the other are in an electrolytic tank, due to the hydrogen outside the escape process of the solution to play a certain amount of stirring, so that the two between the electrolysis of the products of a series of chemical reactions, reaction equations are as follows:

2NaCl+2H2O&#;2NaOH+H2&#;+Cl2 2NaOH+Cl2&#;NaClO+NaCl+H2O

7. In the diaphragm electrolysis of salt water, the total equation of the solution that is listed above the two reaction formulas add up. NaCl + H2O + 2F &#; NaClO + H2 &#; where: F for the Farah electrolysis constant, the value of 26.8 Ampere hours, or 96,487 Coulomb.

8. Sodium hypochlorite generator consists of electrolysis tank, silicon rectifier electronic control cabinet, salt dissolution tank, cooling system and supporting PUVC piping, valves, water jets, flow meters and other components. Add 3~4 dilute salt solution into the electrolysis tank, connect 12V DC, generate sodium hypochlorite by adjusting the electrolysis current electrolysis, absorb and mix the disinfectant solution by the water jet, or measure the disinfectant solution through the mixer by the metering pump.

The above is the working principle of sodium hypochlorite generator is simple, I hope to help the big, will also be released from time to time the knowledge of sewage treatment equipment maintenance and management, mixing should be big continue to pay attention to us!

Sodium hypochlorite generator is a device used to generate sodium hypochlorite solution, which is commonly used for the disinfection of swimming pools, drinking water and industrial wastewater. Sodium hypochlorite is a strong oxidizing agent with bactericidal, disinfectant and bleaching properties.

The working principle of sodium hypochlorite generator is to produce sodium hypochlorite by electrolyzing salt water.

Specifically, a sodium hypochlorite generator usually consists of an electrolyzer in which an anode and a cathode are inserted. The electrolyzer is filled with brine, usually a sodium chloride (NaCl) solution.

When an electric current is turned on, an electrolytic reaction occurs between the anode and cathode. At the anode, chloride ions (Cl-) are oxidized to chlorine gas (Cl2), while at the cathode, water is reduced to produce hydrogen gas (H2) and hydroxide ions (OH-).

The chlorine gas produced reacts with water to form hypochlorous acid (HClO) and hydrochloric acid (HCl). Hypochlorous acid is the active ingredient of sodium hypochlorite, which has strong oxidizing and bactericidal disinfecting ability.

In order to improve the efficiency of sodium hypochlorite generation, generators usually employ measures such as increasing the area of the electrolyzer, improving electrode materials, and optimizing the concentration and temperature of the electrolyte. In addition, the production and concentration of sodium hypochlorite can be regulated by controlling the current density, electrolysis time and flow of electrolyte.

The generated sodium hypochlorite solution can be transported to the water to be treated for disinfection, sterilization or oxidation through an appropriate piping system.

The operating principle of the sodium hypochlorite generator is based on an electrolytic chemical reaction which, through proper design and operation, can effectively produce sodium hypochlorite solution for water treatment and other related applications. It is important to note that when operating and using the sodium hypochlorite generator, it is important to follow safe operating procedures in order to prevent chlorine leakage and other safety issues. It is also necessary to select the appropriate generator model and operating conditions according to the specific water treatment needs and water quality characteristics.

 When using the sodium hypochlorite generator, it is recommended that the equipment be regularly inspected, cleaned, replaced and other maintenance work to effectively extend its service life and improve operational efficiency.

The cleaning steps of sodium hypochlorite generator are as follows:

1. Turn off the generator and cut off the power supply;

2. Remove the electrode and membrane of the generator. 3;

3. soak the electrodes and membranes in clean water and gently brush them with a brush to remove the dirt on the surface;

4. Place the main body of the generator in clean water, add appropriate amount of cleaning agent and soak for 1-2 hours. 5;

5. Rinse the main body of the generator with clean water until it is clean;

6. install the electrode and membrane back into the generator, turn on the power and check whether the equipment is running normally.

When cleaning the sodium hypochlorite generator, you need to pay attention to safety, avoid the use of corrosive cleaning agents, and at the same time, strictly comply with the operating procedures of the equipment to avoid damage to the equipment.
