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)塵器主要有兩(liang)種(zhong)(zhong)結構形式，一(yi)種(zhong)(zhong)是(shi)使用耐腐蝕(shi)導(dao)電(dian)材料（可以為導(dao)電(dian)性能(neng)優良的的非(fei)金屬(shu)材料或(huo)具有耐腐蝕(shi)特性的金屬(shu)材料）做集塵極，另(ling)一(yi)種(zhong)(zhong)是(shi)用通過(guo)噴水或(huo)溢流水形成導(dao)電(dian)水膜(mo)，利(li)用不導(dao)電(dian)的非(fei)金屬(shu)材料做集塵極。
