摘　　要：采用线圈式低温等离子体介质阻挡反应器降解CS2,通过控制CS2浓度、流量及放电电压等影响因素,探讨CS2在氮气和模拟空气背景下的降解率。结果表明:模拟空气和氮气背景下,CS2质量浓度为600mg/m3,流量为0.30m3/h,电压为5 000V时,CS2的降解率分别为90.3%、68.9%。模拟空气背景下尾气成分主要包括SO2、COS、CO2、CO。参数控制在适当范围内,可以提高CS2的降解率。CS2 was degraded by a coil-type low temperature plasma dielectric barrier reactor in this paper.The degradation rate of CS2 under nitrogen and simulated air background gas was investigated by controlling the factors such as CS2 concentration,flow rate and discharge voltage.The results showed that when the CS2 concentration was600 mg/m3,the flow rate was 0.30 m3/h,and the voltage was 5 000 V,degradation rate of CS2 was 90.3% and 68.9%,respectively with simulated air and nitrogen as background gas.The main components in exhaust gas were SO2,COS,CO2,and CO when the background gas was simulated air.The degradation rate of CS2 could be improved when the parameters were appropriate.
