电除尘器取代旋风除尘器的效益分析

简要地叙述了原煤及粉煤灰的特性， 介绍改造后的电除尘器的主要技术参数， 强调了在改造方案中采用钢性结构、宽间距、分小区供电等一系列措施。更新后的高压静电除尘器， 经市环保局监测验收， 除尘效率由７５．１ ％ 提高到９８．９３ ％ ， 每年可减少向大气排放烟尘５．９６ ｋｔ、节约用电３５０ ＭＷ·ｈ 、可多发电７２０ ＭＷ·ｈ ， 取得了较好的环境效益和经济效益。

Benefit analysis after electrostatic precipitator to replace cyclone

At first the raw coal and fine ash qualities were introduced in this paper. The main technical parameters of the electrostatic precipitator after technical reform and a series of measures in the reform scheme were introduced. The cleaning efficiency of the electrostatic precipitator was increased from 75 1% of the cyclone to 98 93%. A better benefit of environment and economy was gained such as the dust emission reduced 5 957 5 t/a, power consumption reduced 350 MWh/a and power generation can be increased 720 MWh/a.
