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(shi)電(dian)除(chu)塵(chen)(chen)器主要有(you)兩種(zhong)(zhong)結構形(xing)式(shi)，一種(zhong)(zhong)是(shi)使用(yong)耐腐(fu)蝕(shi)導(dao)電(dian)材料（可以為(wei)導(dao)電(dian)性(xing)能(neng)優良的的非(fei)金屬材料或具有(you)耐腐(fu)蝕(shi)特性(xing)的金屬材料）做集塵(chen)(chen)極(ji)，另一種(zhong)(zhong)是(shi)用(yong)通過噴水(shui)(shui)(shui)或溢流(liu)水(shui)(shui)(shui)形(xing)成導(dao)電(dian)水(shui)(shui)(shui)膜(mo)，利用(yong)不導(dao)電(dian)的非(fei)金屬材料做集塵(chen)(chen)極(ji)。
