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(chen)器主要(yao)有兩種(zhong)結構形式，一種(zhong)是使用(yong)(yong)耐(nai)腐蝕導(dao)(dao)電(dian)材料(liao)（可以(yi)為導(dao)(dao)電(dian)性能優良的的非金屬(shu)材料(liao)或具有耐(nai)腐蝕特性的金屬(shu)材料(liao)）做集塵(chen)極(ji)，另一種(zhong)是用(yong)(yong)通過噴水或溢流水形成導(dao)(dao)電(dian)水膜，利用(yong)(yong)不導(dao)(dao)電(dian)的非金屬(shu)材料(liao)做集塵(chen)極(ji)。
