Introduction to Sodium Hypochlorite Generators
Sodium hypochlorite (NaOCl) is widely used as a disinfectant in municipal water systems, swimming pools, and industrial processes. Traditional storage and transportation of sodium hypochlorite are risky due to its corrosive and unstable nature. A Sodium Hypochlorite Generator produced by Siyuan solves this problem by allowing on-site production, ensuring safety, cost efficiency, and continuous availability.
- Eliminates storage hazards
- Reduces operational costs
- Ensures consistent chlorine concentration
Working Principle
The generator works primarily through electrolysis, converting common salt (NaCl) into sodium hypochlorite and hydrogen gas. The process involves a series of carefully controlled steps:
- Salt Solution Preparation: Dissolving salt in water to form brine.
- Electrolysis: Brine is passed through an electrolytic cell where electric current splits the molecules.
- Sodium Hypochlorite Formation: Chlorine reacts with the remaining water to produce NaOCl.
- Collection and Dilution: The produced sodium hypochlorite is collected and diluted to the desired concentration.
| Step | Purpose | Outcome |
|---|---|---|
| Brine Preparation | Dissolve salt | Ready for electrolysis |
| Electrolysis | Split molecules | Produces chlorine and hydrogen |
| Reaction with Water | Form NaOCl | Generates disinfectant solution |
| Collection & Dilution | Adjust concentration | Safe, ready-to-use solution |
