The concept of chlorination machine:
It is a device that adds chlorine gas to water. The chlorine gas changes from liquid chlorine to gaseous chlorine. Generally, the chlorine in the liquid chlorine cylinder is volatilized from the liquid to the gaseous state through the following equipment. The chlorine bottle angle valve, the flexible copper tube, the chlorine gas filter, the chlorine gas pressure Table, pressure reducing valve (used when the amount of chlorine is large), vacuum regulator, chlorinator, ejector. The simplest chlorination system also needs to consist of three parts: a vacuum regulator, a chlorinator (controller), and a ejector. At present, most of the chlorinators used in China are imported brands, mainly including American Inco, American Capital, American W@T, German ALLDOS and other products. The control of the chlorinator has flow proportional control and residual chlorine control (or compound loop control). The related peripheral equipment involved are chlorine bottle, chlorine leak alarm, residual chlorine analyzer, and chlorine leakage absorber.
Automatic control method
Can be divided into three types: 1. Flow ratio control, 2. Residual chlorine feedback control, 3. Compliance with loop control, high and low peak time series proportional control, PLC remote control. Liquid chlorine cylinders are said to be part of the chlorination system, and other parts are also complete sets of equipment for safe use of chlorine, chlorine leak alarms, etc.
The liquid chlorination disinfection process is very mature at this stage, with few by-products and moderate cost control. Chlorine dioxide disinfection, relatively high by-products, relatively high cancer, moderate cost. Ozone anti-virus is fast, but High preparation cost, large investment, no continuous killing ability. Not suitable for long-distance water supply. UV disinfection, high cost, high cost of replacing lamp at the end, short anti-virus time, water plant scale can not be too large.
Advantages of liquid chlorination
1. The controllability of residual chlorine can adjust the amount of chlorine added according to the quality of source water to ensure the safety of users. 2. Residual chlorine can achieve continuous anti-virus effect during water transportation to ensure that bacteria reproduce. 3. Chlorine gas disinfection can more completely consume ammonia nitrogen ions in water to facilitate the dosing of water treatment process and reduce the cost of dosing.
