摘要
低温等离子体(NTP,Non-thermal plasma)在净化汽车尾气过程中发生一系列复杂的化学反应,以粒子间碰撞理论为基础,建立NTP净化NO、O_2和N_2三相气体的化学反应动力学模型,通过求解数值模型,分析尾气中O_2浓度对NO净化效率的影响,对生成物O3浓度的影响,对生成的氧自由基(O)的影响。该研究对NTP技术在汽车尾气净化中的应用具有促进作用。
A series of complex chemical reactions occur when the automobile exhaust is purified by non-thermal plasma, based on the collision theory between particles. The three-phase gas （N2, NO, O2） dynamicsmodel was established for NTP purify NO, the trend of NO, NO2, O2, O3 and O concentration in the modelwas analyzed, by solving the numerical model. The trend of NO, NO2, O2, O3 and O concentration in themodel was analyzed. This research can promote the application of NTP technology in automobile exhaustpurification.
