摘　　要：为系统研究高效电源除尘技术,分析了各类高效电源的实际应用情况,从而明确了高效电源除尘技术通过改善粉尘荷电特性来提高除尘效果;同时指出高频电源更适宜于高比电阻高粉尘的收集、脉冲电源和三相电源更适宜于高比电阻细小粉尘颗粒的收集,高效电源除尘技术组合应用并结合其他除尘技术才能实现烟尘的超低排放。因此,高效电源除尘技术是烟尘超低排放改造的一条优选技术路线。In order to study the dust removal technology for the system with high-efficiency power supply,the practical application of various high-efficiency power supplies are analyzed.It is clarified that the dust removal technology with high-efficiency power supply can improve the dust removal effect by improving the dust charge characteristics.At the same time,it is pointed out that high frequency power supply is more suitable for high resistance and high dust collection,pulse power supply and three phase power supply are more suitable for high resistance fine dust particles collection.Combining application of high efficiency power supply dust removal technology with other dust removal technologies can effectively realize the ultra-low emission of dust. Therefore,the high efficiency power supply dust removal technology is a preferred technology route for ultra-low emission.
