高压脉冲电晕处理发动机尾气中的NO的实验研究

Experimental investigation of removing NO from exhaust gas by pulse corona discharge

本文通过对高压脉冲电晕放电产生的等离子体活性物质对发动机尾气中的NO进行活化 ,研究其净化率与电压、频率、风速以及初始浓度的关系及其相互之间的影响 ,同时研究NO的产物NO2 随电压、频率、风速以及初始浓度的生成关系 ,实验表明 ,NO的净化率能够达到 5 0 %以上 ,在风速不大的条件下 。

The releasing plasma had activated the NO from exhaust gas in this paper. The relationships of the purifying ratio and the pulsed voltage, the frequency, the current velocity, the commencing concentration, and the influence of each other, had been investigated. At the same time, the relationships between the generation of NO 2, the result of the NO and the influent factors, had been investigated too. The experiment shows that the purifying ratio can reach to 50%, and in the condition of normal wind velocity the main product of NO is NO 2.
