摘　要：为满足大多数柴油机排气流量的要求，必须扩大单管静电旋风捕集器所能处理的排气流量。在研究了用于柴油机的静电旋风捕集器的清灰方案之后，分析了多种结构方案，确立了多个单管静电旋风捕集器并联的方案，并设计制造了多管并联的静电旋风捕集器。试验结果表明，该多管静电旋风捕集器具有高捕集效率、低排气背压、大流量及可有效清灰等特点。

Abstract：To meet exhaust gas volume requirements of most diesel engines,the gas volume that the single-pipe ESCP can treat should be increased.After studying particles layer dislodging problem and analyzing some structure schemes,a parallel connection of some single-pipe ESCP scheme was selected,and a parallel connection multi-pipe ESCP has been developed.Test results show that the multi-pipe ESCP can trap diesel particulate efficiently with low back-pressure at high gas volume and dislodge particles layer effectively.
Keywords：Diesel particulate;ESCP;Structure scheme;Parallel connection multi-pipe ESCP
