内容摘要:除尘器骨架过滤除尘的机理是筛滤效应、直接截留、扩散沉降、惯性碰撞以及静电吸附等短程捕集机理的综合作用。

除尘袋笼过滤除尘的机理是筛滤效应、直接截留、扩散沉降、惯性碰撞以及静电吸附等短程捕集机理的综合作用。当含尘空气通过网格、织物、非织造布、泡沫塑料等滤料时,粉尘在滤料内部或表面形成的粉尘层,以及粉上层所形成的过滤层的捕集,使其从气流中分离掉。除尘器骨架的质量直接影响滤袋的过滤状态和使用寿命。电除尘配件是利用高压直流电场,使含尘气体中的粉尘微粒荷电,在电场力的作用下,沉积于沉降及的表面上,再经振打力的作用,使成片状的粉尘落入装置中,从而使通过电除尘器的烟气净化,达到排放标准,是为火力发电、冶金和有色金属等工业废气净化的理想设备。

除(chu)尘袋笼根据应(ying)用领(ling)域的不同有着不同的产品形态,我们就来(lai)为大家(jia)介绍其中比较常见的两种:
