Abstract:采用不锈钢多针作为高压电极系统,水膜为低压电极.负直流高压电源供电,含二氧化硫(SO2)的污染气体从高压电极系统的轴向进入,沿着电晕放电电场从水膜上方通过,在电晕放电等离子体和水吸收共同作用下,生成硫酸使SO2得到脱除.主要研究了放电电压、气体中SO2初始浓度和气体在电极系统的停留时间对脱硫效果的影响,并测试了水中SO32-和SI42-离子浓度,分析SO2脱除机制.结果表明,电晕放电和水吸收对SO2脱除具有很好的协同作用,脱硫效果明显升高,SO2转变生成硫酸量的体积分数提高;脱硫效果随电压增加和停留时间的增加而增加,初始浓度对脱硫效果有影响.当SO2初始浓度(体积分数)为430×10-6,施加电压为14.5 kV,停留时间为7.5 s时,脱硫效率达90%以上.
