A sodium hypochlorite generator is a device that generates a sodium hypochlorite generator solution by electrochemically reacting low concentration salt water through an electrified electrode. 

When working, first connect the power supply, and the sodium hypochlorite generator will add ordinary industrial salt (about 0.35 yuan per kilogram) to the salt melting device to dissolve it into about 10% saline water. Open the valve and let the saline water filter and precipitate into the salt storage tank; Then, activate the self dispensing water switch, and the equipment will automatically dispense saline water to a concentration of about 3.5% of dilute saline water; Open the valve again and adjust the flow meter, allowing the mixed saltwater to pass through a sandwich electrolytic cell composed of a set of anode and cathode tubes according to the set flow rate; At the end of the sodium hypochlorite generator, turn on the rectifier current switch and open the cooling water valve to cool the electrolytic cell. The sodium hypochlorite generator starts working. In this way, the entire equipment produces a standard sodium hypochlorite generator liquid (with a concentration of about 1%); Finally, the medicine automatically flows into the medicine storage tank, making it easy to store and add at any time.

Backwashing:After each shift is completed, it is necessary to backwash once. When backwashing, first open the vent valve to drain the salt water trapped in the pipeline, then open the backwash vent and inlet water valves, rinse for about 10 minutes, then open the vent valve to drain the accumulated water, and use it next time.

Pickling:The generator needs to be pickled once for a total of 250 hours of operation. Depending on the water quality, the pickling cycle should be extended or shortened accordingly. During pickling, all drain valves should be opened first to drain the accumulated salt water in the pipeline. Then, the acid inlet and outlet valves should be opened until acid water flows out of the organic pipe in the acid discharge pipe. After the acid water is soaked in the electrode tube for 1-2 hours, the acid water should be drained and then backwashed again. Generally, the concentration of dilute hydrochloric acid is about 10%.

① During normal automatic operation, there is no need for dedicated personnel to manage it. One salt injection can work for 7-10 days. When there is a shortage of salt water, the machine will automatically shut down and sound an alarm. During salt injection, the generator must be backwashed once, and it must be pickled once every month of operation.

② During the operation of the equipment, it is strictly prohibited to operate without cooling. If the unit stops water supply, the equipment is strictly prohibited from use.

③ Regularly check if the power supply wiring bolts are loose and hot, and if the filter mesh in the high-level salt box is blocked, and promptly eliminate it.

④ Try to avoid fireworks indoors, maintain good ventilation, and assign part-time personnel for management.

The main way of sodium hypochlorite generator disinfection and sterilization is to form hypochlorite through its hydrolysis, and hypochlorite further decomposes to form new ecological oxygen [O]. The extremely strong oxidation of new ecological oxygen denatures proteins on bacteria and viruses, and the sodium hypochlorite generator kills pathogenic microorganisms. In fact, the principle of chlorine disinfection is mainly to produce hypochlorous acid and then release new ecological oxygen [O].

According to chemical measurements, the PPM concentration sodium hypochlorite generator is almost completely hydrolyzed into hypochlorite in water, and its efficiency is higher than 99.99%. The process can be simply represented by chemical equations as follows:

NaClO + H2O ＝ HClO + NaOH

HClO → HCl + [O]

Secondly, during the sterilization and virus killing process of hypochlorite, the sodium hypochlorite generator can not only act on the cell wall and virus shell, but also penetrate into the bacterial (virus) body due to the small molecule of hypochlorite, which carries no charge. It can react with organic polymers such as bacterial (virus) body proteins, nucleic acids, and enzymes for oxidation, and the sodium hypochlorite generator can kill pathogenic microorganisms.

R-NH-R + HClO → R2NCl + H2O

At the same time, the chloride ions produced by hypochlorite can significantly alter the osmotic pressure of bacteria and viral bodies, and the sodium hypochlorite generator causes their cells to lose activity and die.

In addition, the sodium hypochlorite generator can also decompose trace pesticides remaining on agricultural and sideline products such as vegetables and fruits. The vast majority of pesticides are composed of organic compounds, and the new state oxygen released by the sodium hypochlorite generator can oxidize and decompose these substances. The sodium hypochlorite generator undoubtedly plays a significant role in promoting the development of modern agriculture and fruit and vegetable packaging industry.

It is also worth noting that due to the fact that the disinfectant produced by the sodium hypochlorite generator does not produce free chlorine in water like disinfectants such as chlorine gas and chlorine dioxide, it is generally difficult to form carcinogens that are harmful to human health due to the presence of free chlorine; It is not like ozone, where a very small amount (0.001mg/m3) in the air can cause damage and toxicity to life; Moreover, the sodium hypochlorite generator will not cause severe corrosion to metal pipelines like chlorine reacts with water to form hydrochloric acid.
