Water treatment disinfection chlorine dioxide generator

Water treatment disinfection chlorine dioxide generatorA simple to operate, high conversion rate, high purity, multi-purpose, environmentally friendly multi-stage generator for chlorine dioxide in chemical processes. This chlorine dioxide generator is composed of a kettle reactor through acid resistant conduits and a water jet vacuum unit. The kettle reactor adopts a two-stage or multi-stage reactor. The main reactor is equipped with an air distributor, and the secondary reactor is equipped with a balance pipe. The residual liquid after the reaction can be discharged in compliance with the standard. The generated chlorine dioxide can be used to produce aqueous solutions, as well as stable chlorine dioxide solutions.

(1) System composition

The chemical chlorine dioxide generator consists of a feeding system, a reaction system, a safety system, an automatic control system, and an absorption and dosing system.

(2) Classification

One type is high-purity chlorine dioxide disinfectant generator, and the other type is chlorine dioxide composite disinfectant generator. As the name suggests, the product generated by a pure chlorine dioxide disinfectant generator is chlorine dioxide, while a chlorine dioxide composite disinfectant generator generates a mixed solution of chlorine dioxide and chlorine gas.

(3) Reaction principle

A type of reaction principle: 5NaClO2+4HCl=4ClO2+5NaCl+2H2O or 2NaClO3+H2O2+H2SO4=2ClO2+Na2SO4+O2 ↑+2H2O

2NaClO2+NaClO+2HCl=2ClO2+3NaCl+H2O

Class II reaction principle: NaClO3+2HCl=CLO2+1/2Cl2+NaCl+H2O

Reaction principle of high-purity sulfuric acid method: 2NaClO3+H2O2+H2SO4 → 2ClO2+Na2SO4+O2+2H2O

Water treatment disinfection chlorine dioxide generatorThe structure has been optimized and the material accessories have been selected, making it particularly suitable for the application requirements of chlorine dioxide generators under high acidity, high ClO2 concentration, and high corrosion conditions. For example, special titanium alloy reactors/composite material reactors, metering pumps, and particularly corrosion-resistant polytetrafluoroethylene drug tubes are used, making the chlorine dioxide generator of excellent quality, reliable use, and longer service life.

It can be equipped with a drug flow distributor to complete the simultaneous quantitative dosing of multiple drug points by a generator, with the characteristics of intuitive display and convenient adjustment of the dosage at each point. For water plants that require simultaneous oxidation of source water, disinfection after filtration, and chlorination of factory water, this process configuration has better applicability.
