为了提高对微细粉尘特别是对PM2．5的收集率，寻求对PM2．5收集的最佳方法，以煤粉为研究对象，使用干电极、雾化水电极实验研究了收集效果。通过对两种电极下收集粉尘的收集效果及粒径分布分析，研究了不同收集条件下微细粉尘的凝并效应。结果表明：雾化水电极对PM2．5的累积收集率为干电极的2倍多，收集峰值的粒径由于式电极下的0．6um降至雾化电极下的0．4um；在强电晕放电过程中，雾化液滴的粒径分布范围在35～70um区间，该现象有利于固-液两相物质间的凝并。

In order to improve and optimize the collection efficiency of subtle dust, especially for the PM2.5, we studied the collection efficiency of dry electrode and spray electrode by taking the coal as the research object. According to the analysis of dust particle size distribution between two electrodes,we analyzed the fine dust collection efficiency and coagulational effect under the different collective conditions. The results show that, the collective cumulative percentage of PM2.5 by spray electrode is twice more than that of dry electrode, and the particle size of collection peak declines form 0.6 um by dry electrode to 0.4 um by spray electrode. In the process of strong corona discharge, the distribution interval of atomization droplet size is among 35 - 70 um, this phenomenon is more favorable for the coagulation of solid-liquid two-phase substance.
