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)(chen)器主要有兩種結構形式，一種是使用耐(nai)腐(fu)蝕導電(dian)材料（可以(yi)為導電(dian)性能優(you)良的(de)的(de)非(fei)金屬材料或具有耐(nai)腐(fu)蝕特性的(de)金屬材料）做集塵(chen)(chen)極，另一種是用通過(guo)噴(pen)水或溢流水形成(cheng)導電(dian)水膜，利用不導電(dian)的(de)非(fei)金屬材料做集塵(chen)(chen)極。
