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)器主要有兩種(zhong)結構形(xing)式，一(yi)種(zhong)是使用(yong)耐腐蝕導(dao)電(dian)材料(liao)（可(ke)以為導(dao)電(dian)性能(neng)優良的的非金(jin)屬材料(liao)或具(ju)有耐腐蝕特性的金(jin)屬材料(liao)）做集塵(chen)極(ji)，另一(yi)種(zhong)是用(yong)通過(guo)噴水(shui)(shui)或溢流水(shui)(shui)形(xing)成導(dao)電(dian)水(shui)(shui)膜，利(li)用(yong)不導(dao)電(dian)的非金(jin)屬材料(liao)做集塵(chen)極(ji)。
