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)結構形式(shi)，一(yi)種(zhong)是使用(yong)耐腐蝕導(dao)電(dian)(dian)材料(liao)（可以為導(dao)電(dian)(dian)性(xing)能優良的(de)(de)(de)的(de)(de)(de)非(fei)金(jin)屬(shu)材料(liao)或具有耐腐蝕特性(xing)的(de)(de)(de)金(jin)屬(shu)材料(liao)）做集塵(chen)(chen)極，另一(yi)種(zhong)是用(yong)通過噴水(shui)或溢流水(shui)形成導(dao)電(dian)(dian)水(shui)膜，利(li)用(yong)不導(dao)電(dian)(dian)的(de)(de)(de)非(fei)金(jin)屬(shu)材料(liao)做集塵(chen)(chen)極。
