摘　　要：采用活性氧化铝球为吸附剂,利用脉冲介质阻挡放电反应器对煤油燃烧产生的纳米颗粒物(PM)的去除进行了研究,探讨了不同处理方法、脉冲频率和放电电压对纳米PM去除效果的影响。结果表明:(1)煤油燃烧产生的PM粒径在15~150 nm左右;(2)放电结合吸附对纳米颗粒的去除率显著高于单独放电或单独吸附;(3)脉冲频率对纳米PM去除影响不大;(4)随着放电电压的增加纳米PM去除率增加。The removal of nano particulate matter(PM)from kerosene combustion was studied by using active alumina ball as the adsorbent packed in a pulsed dielectric barrier discharge reactor.The influence of different purification methods,pulse frequency and discharge voltage on PM removal was investigated.The results showed that(1)the diameter of the PM from decane combustion was in 15~100 nm;(2)nano PM removal rate using discharge combined with adsorption was obviously higher than that of discharge or adsorption alone;(3)pulse frequency had little effect on nano PM removal;(4)nano PM removal rate increased with the increase of discharge voltage.
