classification
Chemical chlorine dioxide disinfectant generators are divided into two categories: pure chlorine dioxide disinfectant generators and chlorine dioxide composite disinfectant generators. 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.
Specification and model
The specifications of chlorine dioxide disinfectant generators are determined based on the chlorine dioxide production rate (g/h) of the equipment. The specifications of the chlorine dioxide composite disinfectant generator are determined based on the effective chlorine production rate (g/h) of the equipment.
Principle
A type of reaction principle: 5NaCLO2+4HCL=4CLO2+5NaCl+2H2O or 2NaCLO3+H2O2+H2SO4=2CLO2+Na2SO4+O2+2H2O
Second type reaction principle: NaCLO3+2HCL+CLO2+1/2CL2+NaCL+H2O
Equipment Selection
Selection rules for chlorine dioxide disinfectant generator: divide the daily sewage volume by the operating time, and then multiply by the dosage.
For example, a hospital has a sewage volume of 300 cubic meters and operates for 15 hours, with a sewage volume of 20 cubic meters per hour. According to the dosage of 30 grams per cubic meter.
The equipment model is: 20 cubic meters of sewage * 30 grams of dosage=WHZ-600 grams. The generator model is determined to be WHZ-600
