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)塵器(qi)主要(yao)有(you)兩種(zhong)結構(gou)形式(shi)，一種(zhong)是使用耐(nai)腐(fu)蝕導(dao)電(dian)材料(liao)(liao)（可以為導(dao)電(dian)性能優良的(de)的(de)非金(jin)(jin)屬材料(liao)(liao)或(huo)具(ju)有(you)耐(nai)腐(fu)蝕特(te)性的(de)金(jin)(jin)屬材料(liao)(liao)）做(zuo)集塵極(ji)，另一種(zhong)是用通過噴水或(huo)溢(yi)流水形成(cheng)導(dao)電(dian)水膜，利(li)用不導(dao)電(dian)的(de)非金(jin)(jin)屬材料(liao)(liao)做(zuo)集塵極(ji)。
