摘要
文章介绍了在减少汽车尾气排放中所采用的等离子净化尾气的原理和实际应用。通过高能活性粒子可以直接将尾气分解成单原子分子,或者将其氧化。根据此原理做成的汽车尾气等离子净化系统主要有3个部分组成:等离子反应器、高压高频电源和控制系统。用该项技术还原NOx和脱除颗粒物效果明显,降低了汽车尾气中有害气体的排放。该技术有着广阔的发展前景,但需要投入足够力量进行研究。
This paper introduces the plasma purifier operation principle and application for reducing automotive exhaust gas. Exhaust gas can be directly decomposed into single atom or can be oxidated through active particle. Automotive exhaust gas plasma purifier has 3 main parts, including the plasma reactor, the high frequency and high vohage power supply and control system. Using this technology to restore NO, and remove particulates has made great progress, thereby exhaust gas emissions is improved. Although this technology has broad prospects in the future, it needs sufficient personal and investment to research.
