SO_2和NO在脉冲电晕放电中氧化及影响因素研究

On the Oxidations of SO2 and NO due to Pulse Corona Discharges

采用ＳＯ２和ＮＯ与空气的混合物作为模拟烟气，研究了ＳＯ２和ＮＯ在正、负脉冲电晕放电中的催化氧化及模拟烟气湿度对氧化的影响。结果发现，正脉冲电晕放电对ＳＯ２和ＮＯ的氧化很有效，远优于负脉冲电晕放电；湿度对ＳＯ２的氧化有较大的影响，但没有观察到湿度增大和添加氨水对ＮＯ的氧化有明显的影响；温度对ＳＯ２和ＮＯ的氧化都有较大的影响。

Abstract The catalytic oxidation of SO2 and NO in the positive and negative pulse corona fieldsand the effects of moisture in the model flue gas,a combination of SO2, NO and air, on oxi-dation have been studied experimentally,The results obtained show that the positive coronadischarge is very effective and much better than the negative one for the oxidation of SO2 andNO. The energy utilization of SO2-oxidation and NO-oxulation by the positive pulse corona
