电厂电除尘节能减排技术改造分析

Technical Retrofit on Electrostatic Precipitator of a Power Plant for Energy Saving and Emission Reduction

某电厂电除尘器长期存在除尘性能大幅下降及各电场频繁跳闸问题,通过对电除尘器进行高频电源及控制系统技术改造,减少了烟尘排放及设备能耗,取得了显著的社会效益和经济效益。改造前后运行情况的介绍及效果分析对后续改造项目具有一定的借鉴意义。

The electrostatic precipitator in a power plant has long been troubled by problems such as great decrease in precipitation performance and frequent tripping of various electrostatic fields. The problems have now been solved by technical retrofit on high-frequency power source and control system of the electrostatic precipitator, with the results of reduced dust emission, lowered energy consumption, and remarkable social and economic benefits. The presentation of its operation conditions and the results of related effectiveness analysis before and after retrofit may serve as a reference for future retrofit of similar electrostatic precipitators.
