摘要

对平煤集团坑口电厂电除尘器积灰现象进行了分析

认为其主要原因是原设计的清灰振打装置布置不当

燃用高灰分、高水分劣质煤和电除尘器本体漏风等影响了振打清灰效果。加装变音频吹灰器后

电除尘器清灰效果明显增强

因积灰而产生的故障大为降低

烟气阻力也有所下降

除尘效率得到了提高。

Abstract

An analysis of ash deposition phenomenon in electrostatic precipitator(EP) in Mine Mouth Power Plant under Pingdingshan Coal Group has been carried out. It is believed that the main causes are as follows: the layout of origially designed ash clearing rapping system is improper; firing low-grade coal with high ash content and high water content; air leakage into the EP proper; etc.

affecting the effectiveness of rapping for ash-clearing. After additionally installing soot-blower with varying audio frequency

the effectiveness of ash clearing in EP has been obviouly enhanced

the troubles due to ash deposition being greatly reduced

the flue gas draft loss being also somewhat decreased

improving the efficiency of EP.
