| 摘 要： | 研制了一套高压脉冲电源和介质阻挡放电反应器，通过在常压下放电产生低温等离子体。结合模拟汽车排气试验，对放电电压、脉冲频率、含氧量以及初始浓度影响HC、NOx净化的规律进行了系统研究。研究表明，利用介质阻挡放电产生低温等离子体净化尾气，是一种具有发展前景的排气后处理技术，对汽车尾气NOx和HC的净化具有明显的净化效果。

| Abstract: | A high pulsed power supply and a dielectric barrier discharge reactor is designed, which produc non thermal plasma under normal atmospheric pressure. Meantime, the removal efficiency of NO and HC under the different pulsed voltage, frequency, O 2 concentration and the commencing concentration was investigated based on the simulated exhaust mixtures. The experiment results show that better effects are attained when the technology applies to removing exhaust, which is a most promising aftertreatment for automobile exhausts. |
