| 摘 要： | 脉冲电晕放电是一种能同时脱除烟气中ＳＯ２，ＮＯｘ和飞灰颗粒的新方法。然而在一个电晕放电试验装置上的试验首次发现，在脱除ＮＯｘ的同时产生了一定量的Ｎ＿Ｏ，而且随着电压和停留时间及ＮＯｘ初始浓度的增大，Ｎ＿２Ｏ量也增大。试验还发现，电晕放电对Ｎ＿２Ｏ无分解作用，空气中的氮气在电晕中不生成Ｎ２Ｏ，脱硫及喷氮脱硫不生成Ｎ２Ｏ，ＳＯ２和ＮＨ３对Ｎ＿２Ｏ的生成无影响。讨论了脉冲电晕放电脱硝中Ｎ２Ｏ生成的机理。

| Abstract: | A pulse-energized electron reactor utilizing pulsed streamer corona has been developedfor simultaneous removal of SO2 ,NO_x and particles from effluent gases, However,nitrousoxide formation was observed during NO_x removal. The main parameters that determine theamount of N2O formation in the reactor are the voltage, residence time and initial NOx con-centration. N2O increases with the increase of voltage, residence time and initial NOx concen-tration, Pulsed corona discharge showed no effect on N2O decomposition. No N2O formationwas detected in the reactor from air,air/SO2 mixture and air/SO2/NH3 mixed gases.The ex-perimental results suggest that N2O comes only from the oxidation of NO_x and SO2 has littlecatalyzing effect on the reaction. |
