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(shi)電(dian)(dian)除塵(chen)(chen)器主要有兩種(zhong)結構形(xing)式(shi)，一種(zhong)是使用耐腐蝕(shi)導(dao)(dao)電(dian)(dian)材料(liao)(liao)（可以(yi)為導(dao)(dao)電(dian)(dian)性能(neng)優(you)良的的非(fei)金屬(shu)材料(liao)(liao)或具(ju)有耐腐蝕(shi)特性的金屬(shu)材料(liao)(liao)）做集塵(chen)(chen)極(ji)，另一種(zhong)是用通過噴(pen)水(shui)或溢流水(shui)形(xing)成導(dao)(dao)電(dian)(dian)水(shui)膜，利用不(bu)導(dao)(dao)電(dian)(dian)的非(fei)金屬(shu)材料(liao)(liao)做集塵(chen)(chen)極(ji)。
