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)(dian)(dian)(dian)除(chu)塵(chen)器(qi)主(zhu)要有(you)兩種結構形式，一種是(shi)使(shi)用耐(nai)腐蝕導電(dian)(dian)(dian)(dian)材(cai)料(liao)(liao)（可以為(wei)導電(dian)(dian)(dian)(dian)性(xing)能(neng)優良的的非(fei)金(jin)屬(shu)材(cai)料(liao)(liao)或(huo)具有(you)耐(nai)腐蝕特性(xing)的金(jin)屬(shu)材(cai)料(liao)(liao)）做集(ji)塵(chen)極，另一種是(shi)用通過噴水(shui)(shui)或(huo)溢流水(shui)(shui)形成導電(dian)(dian)(dian)(dian)水(shui)(shui)膜，利用不導電(dian)(dian)(dian)(dian)的非(fei)金(jin)屬(shu)材(cai)料(liao)(liao)做集(ji)塵(chen)極。
