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)器主(zhu)要有(you)兩種結構形(xing)式(shi)，一種是使用(yong)(yong)耐腐(fu)蝕導電(dian)(dian)材料(liao)（可以為導電(dian)(dian)性能優良的(de)的(de)非(fei)金屬(shu)(shu)材料(liao)或(huo)具有(you)耐腐(fu)蝕特性的(de)金屬(shu)(shu)材料(liao)）做(zuo)集塵(chen)極(ji)，另一種是用(yong)(yong)通過噴(pen)水或(huo)溢流水形(xing)成導電(dian)(dian)水膜，利用(yong)(yong)不導電(dian)(dian)的(de)非(fei)金屬(shu)(shu)材料(liao)做(zuo)集塵(chen)極(ji)。
