摘　　要：采用线-筒式电晕反应器对二硫化碳(CS2)废气的去除效果进行了实验研究.实验考察了峰值电压、载气成分和水汽含量等因素对去除率的影响.结果表明:CS2在氩气中的去除效果要好于在氮气中的去除效果,其主要降解产物均为单质硫.在氩气中添加20%的氧气后,CS2的最高去除率从44.9%提高到了63.4%,添加50%的水汽后从44.9%提高到了56.4%.CS2在氩气和氧气混合气中的最终降解产物为CO,CO2,COS和SO2.The removal of CS2 in a wire-in-tube pulsed corona reactor was experimentally investigated. The influences of operation parameters such as pulse voltage, gas composition and water vapor content on the removal of CS2 were investigated. Results showed that the removal of CS2 in Ar gas was more desirable than that in N2 gas. The main product was confirmed to be elemental sulfur. The removal of CS2 increased from 44.9% to 63.4% with the addition of 20% 02 in Ar gas, and from 44.9% to 56.4% with the addition of 50% water vapor in the gas stream. It was found that the main gaseous products of CS2 decomposition with the addition of 02 in Ar gas were CO, C02 , COS and S02.
