Beverage Disinfection Sodium Hypochlorite Generator Of MMO Anode Electrolyzer

Product Specification

Beverage Disinfection Sodium Hypochlorite Equipment of mmo Anode Electrolyzer

Brief Introduction

It is a proven technology to convert ordinary salt (common salt) or sea water, by means of electrolysis into sodium hypochlorite (ELECTRO HYPO) using GEEMBLUE sodium hypochlorite generators (electro chlorination system). It is always applied on-site, at the point of application. No chemicals other than ordinary salt are used throughout the process.

The electrolytic cell is fed a DC current from the rectifier and electrolyzes the diluted brine into sodium hypochlorite solution. Chlorine evolves at the anode surface, while hydrogen and hydroxide evolves at the cathode surface. The secondary reaction of chlorine, sodium and the hydroxyl ion nets sodium hypochlorite (chlorine bleach) at a 0.8% solution. Below 1%, hypo is classified as a non-hazardous chemical although still a very effective disinfectant. The only by-product, hydrogen, is safety vented into the atmosphere.

Principle of sodium hypochlorite generator

Salt solution contains the several kinds of ions such as Na +, H -, when electrolysis, under a certain voltage, as a result of the movement of ions in the electrolyte solution and electrode reaction, the conductive effect occurs, then CL -, OH - such as negative ion to the anode, and positive ions such as Na +, H + to the cathode, and the corresponding electrode discharge occurs, thus carries on the REDOX reaction, the corresponding material production. The electrode reaction and solution reactions is

Electrode reaction:
　 anode: 2Cl- - 2e → Cl2；
　 cathode: 2H+ + 2e → H2；
Solution reaction:

2NaOH + Cl2 → NaCl + NaClO + H2O

Overall reaction as follow:

Na Cl + H2O + DC →NaClO + H2↑

Process

1. Influent water is passed through a water softener.

2. Using softened water to dissolve the salt in a tank to form a concentrated brine solution.

3. Diluted into 2.5%-3% after filtered (If use sea water as raw material, it will be treated before electrolysis)

3. The diluted brine is electrolyzed to a 0.8% solution of sodium hypochlorite.

4. The 0.8% hypochlorite solution flows into a storage tank.
5. The sodium hypochlorite solution will be injected into the pipe by metering pump.

6. The residual chlorine detector will monitor residual chlorine and return feedback to the PLC center.

7. According to preset standards, the PLC Center will adjust the speed of the dosing pump.

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.

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.
