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)電除塵(chen)器主要有兩種(zhong)結構(gou)形式(shi)，一(yi)種(zhong)是(shi)使用耐(nai)腐蝕導(dao)電材(cai)料(liao)(liao)（可以為(wei)導(dao)電性(xing)能優良的的非(fei)金屬材(cai)料(liao)(liao)或(huo)(huo)具有耐(nai)腐蝕特(te)性(xing)的金屬材(cai)料(liao)(liao)）做(zuo)集(ji)塵(chen)極，另一(yi)種(zhong)是(shi)用通過噴水或(huo)(huo)溢流水形成導(dao)電水膜，利用不導(dao)電的非(fei)金屬材(cai)料(liao)(liao)做(zuo)集(ji)塵(chen)極。
