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(chen)器(qi)主(zhu)要有兩種結構形式，一(yi)種是使用(yong)耐腐(fu)蝕(shi)(shi)導電(dian)材(cai)料(liao)（可以為(wei)導電(dian)性(xing)能優(you)良的(de)的(de)非(fei)金屬材(cai)料(liao)或具有耐腐(fu)蝕(shi)(shi)特性(xing)的(de)金屬材(cai)料(liao)）做(zuo)集塵(chen)極，另一(yi)種是用(yong)通過噴水或溢流水形成導電(dian)水膜，利(li)用(yong)不導電(dian)的(de)非(fei)金屬材(cai)料(liao)做(zuo)集塵(chen)極。
