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(chen)器主要(yao)有兩種結構形式，一種是(shi)(shi)使用耐腐蝕(shi)導(dao)電(dian)材料(liao)（可以(yi)為(wei)導(dao)電(dian)性能優(you)良的的非(fei)金(jin)(jin)屬材料(liao)或(huo)具有耐腐蝕(shi)特性的金(jin)(jin)屬材料(liao)）做集(ji)塵(chen)極，另一種是(shi)(shi)用通過噴水(shui)或(huo)溢流(liu)水(shui)形成(cheng)導(dao)電(dian)水(shui)膜(mo)，利(li)用不導(dao)電(dian)的非(fei)金(jin)(jin)屬材料(liao)做集(ji)塵(chen)極。
