NTP净化柴油车尾气的发展现状及前景分析
|
摘要
传统的柴油车尾气净化方法具有净化效率低、质量大、成本高、占用空间大和排气背压高等缺点,在一定程度上阻碍了柴油车的发展,为提高柴油车尾气净化技术的净化性能,低温等离子体(NTP,Non-thermal Plasma)净化柴油车尾气技术得到了广泛的关注。综述了NTP净化柴油车尾气微粒物(PM,Particular Matter)和氮氧化物(NO_x)的机理与发展现状,并对NTP净化技术的发展前景进行分析,提出了NTP与微米木纤维相结合的柴油车尾气净化方法,该方法可克服传统NTP净化器的缺点,并实现PM与NO_x的同时净化。
The traditional diesel exhaust purification method has the disadvantages of low purification efficiency, high quality, high cost, large occupied space and high back pressure, which hinders the development of a diesel vehicle to some extent. In order to improve the purification performance of diesel engines exhaust purification technology, non-thermal plasma technology has received widespread attention to purify diesel exhaust in recent years. This paper reviews the mechanism and development status of NTP purifying diesel exhaust PM and NO_x, and analyzes the development prospect of NTP purification technology, which suggests a kind of diesel exhaust purification method that combined NTP and micron wood fiber, it can overcome the shortcomings of the traditional NTP purifier, while achieving the purification of PM and NO_x at the same time.
