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)除塵器主(zhu)要有兩(liang)種(zhong)結構形式，一種(zhong)是(shi)使用(yong)耐腐(fu)蝕導(dao)電(dian)材(cai)(cai)料(liao)(liao)（可以(yi)為(wei)導(dao)電(dian)性(xing)能優(you)良(liang)的的非(fei)金屬(shu)材(cai)(cai)料(liao)(liao)或(huo)具有耐腐(fu)蝕特性(xing)的金屬(shu)材(cai)(cai)料(liao)(liao)）做集塵極，另一種(zhong)是(shi)用(yong)通過噴水或(huo)溢流水形成導(dao)電(dian)水膜(mo)，利用(yong)不導(dao)電(dian)的非(fei)金屬(shu)材(cai)(cai)料(liao)(liao)做集塵極。
