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)除塵器主要有兩種結構形式(shi)，一種是(shi)使用耐腐(fu)蝕導電(dian)(dian)材料（可以為導電(dian)(dian)性能優(you)良的(de)(de)的(de)(de)非金屬(shu)材料或具有耐腐(fu)蝕特性的(de)(de)金屬(shu)材料）做集塵極，另一種是(shi)用通過噴水(shui)或溢流水(shui)形成導電(dian)(dian)水(shui)膜，利(li)用不導電(dian)(dian)的(de)(de)非金屬(shu)材料做集塵極。
