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)除塵器主要有(you)兩(liang)種結構形式(shi)，一種是使用(yong)(yong)耐腐蝕導電(dian)(dian)材(cai)料（可以為導電(dian)(dian)性能(neng)優良的(de)的(de)非金屬材(cai)料或(huo)具有(you)耐腐蝕特性的(de)金屬材(cai)料）做集(ji)塵極，另一種是用(yong)(yong)通過噴(pen)水(shui)或(huo)溢流水(shui)形成(cheng)導電(dian)(dian)水(shui)膜，利用(yong)(yong)不導電(dian)(dian)的(de)非金屬材(cai)料做集(ji)塵極。
