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(shi)電(dian)除塵器主(zhu)要(yao)有兩種(zhong)結構形(xing)式(shi)，一(yi)種(zhong)是(shi)使用(yong)耐(nai)腐蝕導電(dian)材料(liao)（可以為導電(dian)性(xing)(xing)能優良的(de)的(de)非金屬(shu)材料(liao)或(huo)具有耐(nai)腐蝕特性(xing)(xing)的(de)金屬(shu)材料(liao)）做集塵極(ji)，另(ling)一(yi)種(zhong)是(shi)用(yong)通過噴水或(huo)溢流水形(xing)成導電(dian)水膜，利用(yong)不(bu)導電(dian)的(de)非金屬(shu)材料(liao)做集塵極(ji)。
