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)式電除塵(chen)器主(zhu)要有(you)兩種(zhong)(zhong)結構形(xing)(xing)式，一(yi)種(zhong)(zhong)是使用耐(nai)腐蝕導(dao)(dao)電材料(liao)(liao)（可(ke)以為導(dao)(dao)電性(xing)能優良(liang)的(de)(de)的(de)(de)非(fei)金(jin)屬材料(liao)(liao)或(huo)具有(you)耐(nai)腐蝕特性(xing)的(de)(de)金(jin)屬材料(liao)(liao)）做(zuo)集塵(chen)極，另一(yi)種(zhong)(zhong)是用通過噴水或(huo)溢流(liu)水形(xing)(xing)成導(dao)(dao)電水膜，利用不(bu)導(dao)(dao)電的(de)(de)非(fei)金(jin)屬材料(liao)(liao)做(zuo)集塵(chen)極。
