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。

濕式電除塵器主要有(you)兩(liang)種(zhong)結構形(xing)式，一種(zhong)是使用(yong)耐腐蝕(shi)(shi)導(dao)電材料(liao)（可(ke)以為導(dao)電性(xing)能(neng)優良的(de)的(de)非(fei)金(jin)(jin)屬(shu)材料(liao)或具有(you)耐腐蝕(shi)(shi)特性(xing)的(de)金(jin)(jin)屬(shu)材料(liao)）做集塵極，另一種(zhong)是用(yong)通過噴水或溢流水形(xing)成導(dao)電水膜，利用(yong)不導(dao)電的(de)非(fei)金(jin)(jin)屬(shu)材料(liao)做集塵極。
