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)式電(dian)除塵器主要有兩(liang)種結構形式，一種是使(shi)用(yong)耐(nai)腐蝕(shi)導(dao)電(dian)材料（可以為導(dao)電(dian)性能(neng)優良的(de)的(de)非(fei)(fei)金(jin)(jin)屬(shu)(shu)材料或具有耐(nai)腐蝕(shi)特(te)性的(de)金(jin)(jin)屬(shu)(shu)材料）做集塵極，另一種是用(yong)通(tong)過噴水或溢流(liu)水形成導(dao)電(dian)水膜，利用(yong)不導(dao)電(dian)的(de)非(fei)(fei)金(jin)(jin)屬(shu)(shu)材料做集塵極。
