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)(dian)(dian)除塵器主要有兩種(zhong)結構形(xing)式，一種(zhong)是使(shi)用耐腐蝕(shi)導(dao)(dao)電(dian)(dian)(dian)材料(liao)（可(ke)以為導(dao)(dao)電(dian)(dian)(dian)性能優(you)良的(de)的(de)非金(jin)屬材料(liao)或具有耐腐蝕(shi)特(te)性的(de)金(jin)屬材料(liao)）做集塵極，另一種(zhong)是用通過噴水或溢(yi)流水形(xing)成導(dao)(dao)電(dian)(dian)(dian)水膜，利用不(bu)導(dao)(dao)電(dian)(dian)(dian)的(de)非金(jin)屬材料(liao)做集塵極。
