摘　　要：对脉冲放电烟气除尘与脱除ＳＯ２和ＮＯＸ进行实验研究与分析的结果表明，烟气中的飞灰对ＳＯ２和ＮＯＸ吸附脱除２％～５％，吸附脱除量随着飞灰浓度和烟气含量的增加而增大。在单位体积烟气注入能量为４Ｗｈ／Ｎｍ３和烟气在反应器中停留时间小于３秒，飞灰与水蒸气的协同作用使ＳＯ２和ＮＯＸ脱除率分别达到２３％和３３％。同时，脉冲放电使反应器对飞灰具有良好的协同作用，收集效率为９７％。The combined removal of SO 2,NO X and foyash simulated flue gas is experimentally investigated using pulsed corona discharge.The results show that the flyash in flue gas has adsorption in SO 2,NO X removal process,and the removal efficiency is about 2%～5%.Increasing the concentrations of water and flyash also increases the removal efficiency of SO 2 and NO X.At the injected energy of 4Wh/Nm 3 and less than 3 second of resident time of flue gas in reactor,the removal efficiency of SO 2 that of NO is about 23% and 33% respectively,accounting for the cooperation of flyash and water vapor.Meanwhile,the reactor cnergized by pulse generator has advantages for aerosol particle collection,especially the collection efficiency of flyash is about 97%.
