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(jie)構形(xing)式，一種(zhong)是(shi)使用耐腐(fu)蝕導(dao)電(dian)材(cai)料(liao)(liao)（可以為導(dao)電(dian)性(xing)能(neng)優良(liang)的(de)的(de)非(fei)金(jin)屬(shu)材(cai)料(liao)(liao)或具有耐腐(fu)蝕特(te)性(xing)的(de)金(jin)屬(shu)材(cai)料(liao)(liao)）做集塵極(ji)，另一種(zhong)是(shi)用通過(guo)噴水(shui)或溢流(liu)水(shui)形(xing)成導(dao)電(dian)水(shui)膜(mo)，利用不(bu)導(dao)電(dian)的(de)非(fei)金(jin)屬(shu)材(cai)料(liao)(liao)做集塵極(ji)。
