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)除塵器主要(yao)有(you)兩種結構形(xing)式，一種是使用(yong)(yong)耐腐蝕導(dao)電(dian)材(cai)料（可以為導(dao)電(dian)性能優良的(de)的(de)非(fei)金(jin)屬材(cai)料或(huo)具有(you)耐腐蝕特(te)性的(de)金(jin)屬材(cai)料）做(zuo)集(ji)塵極(ji)，另一種是用(yong)(yong)通過(guo)噴水(shui)或(huo)溢(yi)流水(shui)形(xing)成導(dao)電(dian)水(shui)膜，利用(yong)(yong)不導(dao)電(dian)的(de)非(fei)金(jin)屬材(cai)料做(zuo)集(ji)塵極(ji)。
