Full Automatic Brine Electrolysis Sodium Hypochlorite Generator / Water Chlorination System

Full Automatic Brine Electrolysis Sodium Hypochlorite Generator

Product Description

0.8% Sodium hypochlorite generation system is producing sodium hypochlorite onsite through 3% brine electrolysis(salt and water after saturated), and the whole system is a combination of Softening unit, Filtration unit, Salt dissolving unit, Online proportioning unit, electrolytic unit, rectifier power supply, automatic control systems, storage and dosing unit, etc.

Sodium Hypochlorite is widely used in many water industries. The most applied in drinking water disinfection, on site generation of Sodium hypochlorite is more safely than feeding chlorine gas. Transporting Chlorine gas tank is risky to leakage and lead to explosion.

Generation principle:

The sodium chloride contained in seawater or brine flow between sets of electrodes (anodes and cathodes) in an electrolyzer.

The chemical reactions which take place in the electrolyzer between chlorine and Sodium hydroxide produced by electrolysis.
In the electrolyzer the sodium chloride is completely dissociated into the ions Na⁺ and Cl^-, causes the following electrochemical and chemical reactions:

Electrode reaction:

at the anode: 2Cl^- - 2e → Cl₂；
at the cathode: 2H⁺ + 2e → H₂；
Solution reaction:

2NaOH + Cl₂ → NaCl + NaClO + H₂O

Overall reaction as follow:

NaCl + H₂O + DC →NaClO + H₂↑

Product components

Magneto Electrolyzer

Transparent electrolytic cell, organic glass material.

TA1 titanium electrode, the anode is covered by ruthenium-iridium oxide fine nano coating which is up to 20 layers, ensure more than 5 years service life.

Bipolar electrode connection mode, reduced the heat yield, as well greatly reduced the production of sodium hypochlorite salt consumption and power consumption, plays a positive role in reducing by-product.

Siemens Touch Screen

All running status are shown clearly and all parameters can be adjusted directly by the touch screen.

Siemens PLC

Every step of process and protection of components is detected and controlled by the smart PLC center, safety, reliability.

Geemblue Rectifier

High frequency, stability and constant current rectifier.

Electrical conversion effciency over 90%

The rectifier have multiple protection for input over/under voltage, and output overvoltage / overcurrent / short circuit protection as well as overheat protection, ensure high reliability and security.

Seko Metering Pump

Real-time detect residual chlorine in water, thus convert to 4-20mA signal and feedback to PLC, for controling the dosing rate of dosing pump.
