抑制清灰扬尘 有效提高除尘效率

Improve Dust Removal Efficiency by Restraining Dust in Secondary Dust Removal

本文针对最常见的电除尘器清灰扬尘问题,从新的角度进行了分析和论述。澄清了某些场合电场工作效率不高的原因未必是清灰振打不力等事实,阐述了阴极在一定程度附灰对除尘效果可能带来有利的影响。指出本体与电源的合理选配是保证极板附灰有效清除、减少粉尘逃逸的关键因素,提出了通过改变极板形状进一步抑制清灰扬尘、切实提高除尘效率的设想。

This paper analyzes the secondary dust removal in electrostatic precipitator in new view, clari- fies the fact that low electric field working efficiency in some applications is not resulted from insufficient cleaning rapping, and expatiates that certain dust accumulated on discharge electrode could have favora- ble influence on dedusting effect. This paper indicates reasonable matching between machinery part and power supply is the key factor to clean the dust on collecting electrode and reduce dust escape, and pro- poses the assumption to further restrain secondary dust evolution and improve dcdusting efficiency by changing the shape of collecting electrode.
