濕式電除塵器是一種用來處理含微量粉塵和微顆粒的新除塵設備，主要用來除去含濕氣體中的塵、酸霧、水滴、氣溶膠、臭味、PM2.5等有害物質，是治理大氣粉塵污染的理想設備。

濕式電除塵器通常簡稱WESP，與干式電除塵器的除塵基本原理相同，要經歷荷電、收集和清灰三個階段。

濕式電(dian)除塵(chen)器(qi)主要(yao)有兩(liang)種結構形式，一種是使用(yong)耐腐(fu)蝕導(dao)(dao)電(dian)材(cai)料(liao)（可以為導(dao)(dao)電(dian)性能(neng)優良的(de)的(de)非(fei)金(jin)屬材(cai)料(liao)或具有耐腐(fu)蝕特性的(de)金(jin)屬材(cai)料(liao)）做集塵(chen)極(ji)，另一種是用(yong)通(tong)過噴水(shui)(shui)或溢流(liu)水(shui)(shui)形成導(dao)(dao)電(dian)水(shui)(shui)膜，利用(yong)不導(dao)(dao)電(dian)的(de)非(fei)金(jin)屬材(cai)料(liao)做集塵(chen)極(ji)。
