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)除塵器主要有兩種結構形式，一(yi)種是使用耐(nai)腐蝕導(dao)電(dian)材(cai)料(liao)（可以為導(dao)電(dian)性(xing)能(neng)優良的的非金(jin)(jin)屬(shu)材(cai)料(liao)或具有耐(nai)腐蝕特性(xing)的金(jin)(jin)屬(shu)材(cai)料(liao)）做(zuo)集塵極，另一(yi)種是用通過噴水或溢流水形成導(dao)電(dian)水膜，利用不(bu)導(dao)電(dian)的非金(jin)(jin)屬(shu)材(cai)料(liao)做(zuo)集塵極。
