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(zhong)(zhong)結(jie)構(gou)形(xing)式，一種(zhong)(zhong)是(shi)使用(yong)(yong)耐(nai)腐蝕導(dao)電(dian)材料（可以為(wei)導(dao)電(dian)性能優良的的非金(jin)屬材料或具有耐(nai)腐蝕特性的金(jin)屬材料）做(zuo)集塵極，另(ling)一種(zhong)(zhong)是(shi)用(yong)(yong)通過噴水(shui)或溢流水(shui)形(xing)成導(dao)電(dian)水(shui)膜，利用(yong)(yong)不導(dao)電(dian)的非金(jin)屬材料做(zuo)集塵極。
