脉冲等离子体烟气脱硫和除尘的协同效应

Synergism of Glue Gas Desulphurization and Precipitation by Pulsed Plasma

研究了高压窄正脉冲电晕等离子体同时脱硫和除尘的规律以及两者在脱除过程中的相互影响。结果表明，窄正脉冲电晕对烟气ＳＯ＿２的氧化脱除很有效，除尘效果优于传统静电除尘器的直流电晕方式；烟气中粉尘和ＳＯ＿２之间在脱除过程中存在良好的协同效应，对降低整个过程的能耗有利；肯定了在传统静电除尘设备基础上，采用窄脉冲供能集烟气脱硫和除尘为一体的可行性。

simultaneous desulphurization and ash precipitation of flue gas by high-voltage narrowpositive pulse corona induced plasma and the mutual influences between them are studied. Itis shown that the narrow positive pulse corona is very effective for the removal of SO2 by oxi-dization from the flue gas and the ash precipitation is better than that by DC corona in tradi-tional ESP. There exists good synergism during the ash and SO2 removal,which is favorablefor reducing the energy consumption.
