Abstract
研究分析了介质阻挡放电低温等离子技术脱除NO机理、NO初始浓度和氧气含量对NO脱除效率的影响。实验结果表明,在20 KV时,O2含量从0%增加到8%,NO在各个电压下的脱除效率均下降,介质阻挡放电脱除NO的效率也由60%下降到33.8%。随着NO初始浓度的增加,NO脱除效率也由83%下降到33%。NO初始浓度的提高、O2含量的增加都会导致NO的脱除率的明显降低。 The influence of NO concentration and oxygen content on the removal efficiency of NO by low temperature plasma technique with dielectric barrier discharge was studied and analyzed. NO removal efficiency was analyzed. Experimental results show that at 20 KV, O2 content increased from 0% to 8%, NO removal efficiency at each voltage decreased, and NO removal efficiency of dielectric barrier discharges dropped from 60% to 33.8%. With NO initial concentration increases, NO removal efficiency has dropped from 83% to 33%. NO initial concentration of O2 and removal of content increase will result in the decrease of NO rate significantly.
