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(chu)塵(chen)器(qi)主要有兩種結構形式，一種是使(shi)用耐腐蝕導(dao)電(dian)材料(liao)（可以為導(dao)電(dian)性能優良的(de)的(de)非(fei)金(jin)屬(shu)材料(liao)或(huo)具有耐腐蝕特性的(de)金(jin)屬(shu)材料(liao)）做集塵(chen)極，另一種是用通過噴水或(huo)溢流水形成導(dao)電(dian)水膜，利用不導(dao)電(dian)的(de)非(fei)金(jin)屬(shu)材料(liao)做集塵(chen)極。
