【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NO的去除率随放电管的放电电压、NO的初始浓度以及气体流量的改变而变化的规律进行研究。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,对汽车尾气的净化具有明显的净化效果。更多还原

【Abstract】 A high pulsed power supply and a dielectric barrier discharge reactor is designed, which produce non-thermal plasma under normai atmospheric pressure. From the experiment, we have got the removal rate of NO as a function of the input voltage of the dischage the initially fed NO concentration and the flux of the mixed gas.The experiment results show that better effects are attained when the technology applies to removing exhaust ,which is a most promising after treatment for automobile exhausts.更多还原
