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(zhu)要有兩種結構(gou)形(xing)式，一種是(shi)使用(yong)耐腐蝕導(dao)電(dian)材料（可以(yi)為導(dao)電(dian)性能(neng)優良的(de)(de)的(de)(de)非(fei)金(jin)屬材料或具(ju)有耐腐蝕特性的(de)(de)金(jin)屬材料）做集塵極，另一種是(shi)用(yong)通過噴水或溢流水形(xing)成導(dao)電(dian)水膜，利用(yong)不導(dao)電(dian)的(de)(de)非(fei)金(jin)屬材料做集塵極。
