Abstract:模拟烟气的脉冲放电等离子体活化法脱除ＳＯ２产物分析结果表明：在温度６０℃～７０℃，氨硫化学计量比为１∶１条件下，（ＮＨ４）２ＳＯ４含量占脉冲放电脱硫产物含量的８０％以上；５０％左右的产物吸附于反应器内，其余部分随着尾气排出；提高电压有利于正盐的生成；尾气与反应器中（ＮＨ４）２ＳＯ４比值也随之增大．测定了不同温度下（ＮＨ４）２ＳＯ３的化学平衡常数，得出在氨硫化学计量比１∶１，温度６０℃～７０℃的脉冲烟气脱硫条件下，均相的尾气中不存在亚硫酸盐产物．证实了在多相的胶体反应气中，ＳＯ２首先与ＮＨ３等结合生成ＨＳＯ－３，后经过链反应机制被脱除是脉冲脱硫的主要氧化途径；ＳＯ２以分子形式直接被自由基氧化不是脉冲脱硫的主要途径
