Automatic control technology for chlorine usage
Thread Content
Since chlorine is quite dangerous, automated control technology is now required for its use. Since not much is known about it, please help out. Thank you!
Chlorine is a highly toxic chemical, with an allowable concentration in the air of 1 mg/m3. Therefore, high requirements are placed on the equipment. Regarding automatic control technology, it depends on how chlorine is used, that is, it is determined by the production process. However, certain considerations should be given to the materials of the equipment and pipelines.
Our plant uses an automatic chlorination system of German brand Jessco, which is composed as follows: 1. Chlorine cylinder (with electronic scale) → Liquid chlorine evaporator → Filter → Pressure reducing valve → Vacuum regulator → Chlorination unit → Water jet pump → Chlorination point. 2. Chlorine leakage absorption unit: air inlet fan chlorine leakage absorption tower alkali solution pump air outlet, via water inlet pipeline, air inlet, waste discharge pipeline, and air outlet. Name Parameter Automatic vacuum chlorination system 150kgCL/h Electric vacuum regulator 190kgCL/h Evaporator 150kgCL/h Water jetter 8000PPD Electronic scale for chlorine cylinders, with a maximum loading capacity of 2000kg; features remote signal transmission and upper/lower limit alarms Chlorine absorption device, with an absorption capacity of 1000kg/h Chlorine leakage alarm, electrochemical type, dual probes, 0–10PPM Residual chlorine analyzer, electrochemical type, 0–20PPM
