Research on the Treatment Technology of Volatile Organic Pollutants in Chemical Waste Gas in Urban Environment
In order to develop a new treatment technology for volatile organic pollutants in chemical waste gas,in order to reduce the cost and secondary pollution,O2+H2O was used as the free radical source to reduce the volatile organic pollutants in chemical waste gas.Based on the treatment technology of free radical shower VOCs induced by DC corona discharge,a treatment device was built to collect volatile organic pollutants from a dye chemical plant.The equipment for preparing free radical source substances is designed,which con-sists of flowmeter,dry oxygen,oxygen constant temperature humidification device and barometer.The oxygen after constant temperature humidification is introduced into the nozzle electrode,and the treatment target is achieved under the action of corona discharge.The deg-radation efficiency will increase with the increase of voltage.At low voltage,the degradation efficiency gap is large,and when the voltage increases,the gap gradually narrows.
