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(shi)式電(dian)(dian)(dian)除塵(chen)(chen)器主要有兩種(zhong)結(jie)構形式，一種(zhong)是(shi)使用(yong)(yong)耐腐蝕導(dao)電(dian)(dian)(dian)材(cai)料（可(ke)以為導(dao)電(dian)(dian)(dian)性能優良的(de)的(de)非金屬材(cai)料或(huo)具有耐腐蝕特性的(de)金屬材(cai)料）做集塵(chen)(chen)極(ji)，另一種(zhong)是(shi)用(yong)(yong)通過噴水(shui)(shui)或(huo)溢(yi)流水(shui)(shui)形成導(dao)電(dian)(dian)(dian)水(shui)(shui)膜，利用(yong)(yong)不導(dao)電(dian)(dian)(dian)的(de)非金屬材(cai)料做集塵(chen)(chen)極(ji)。
