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)除塵器主要有兩種(zhong)結構形式，一(yi)種(zhong)是使(shi)用(yong)耐腐(fu)蝕(shi)導(dao)電(dian)材(cai)料(liao)（可(ke)以為導(dao)電(dian)性(xing)能優良的(de)(de)的(de)(de)非金屬材(cai)料(liao)或(huo)具有耐腐(fu)蝕(shi)特性(xing)的(de)(de)金屬材(cai)料(liao)）做(zuo)集(ji)塵極，另一(yi)種(zhong)是用(yong)通過噴水或(huo)溢流水形成導(dao)電(dian)水膜，利用(yong)不導(dao)電(dian)的(de)(de)非金屬材(cai)料(liao)做(zuo)集(ji)塵極。
