摘要
为了提高静电除尘器对于微细粉尘的收集率,减弱离子风对除尘效率的影响。本文选取建筑砖粉为研究对象,将静电除尘器中的常规收尘极板改变为多孔纤维状极板,通过分析常规收尘极板和新型极板在不同极板间距下收集粉尘的粒径分布,研究了新型极板对离子风以及微细粉尘收集率的影响。结果表明:新型收尘极板不仅可以有效地减弱离子风风力以及其双螺旋结构作用的范围,同时由于纤维布料良好的黏附性,有效减弱了微细粉尘的二次扬尘现象,进而提高了除尘器对微细粉尘的收集效率。
In order to improve the collection rate of electrostatic precipitator for fine dust,and abate ion wind effects on dust removal efficiency.This article selected the building brick powder as the research object,by changing the conventional dust collecting plate in electrostatic precipitator into the porous fiber plate,the experiment based on the analysis of the particle size distribution of the dust,which the conventional dust collecting plate and the new plate collected under different plate spacing,studied to the effect of the new plate on fine dust collection rate and ion wind.The results show that,the new type dust collecting plate can not only effectively abate ion wind power and the effect scope of its double helix structure.At the same time,because of the good adhesion of fiber cloth,it effectively reduces the secondary dust of fine dust,thus improves the fine dust collection efficiency of electrostatic precipitator.
