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)除塵(chen)器(qi)主(zhu)要(yao)有兩種結構形(xing)式(shi)，一種是使用(yong)耐腐蝕(shi)導電(dian)材料(liao)（可(ke)以(yi)為導電(dian)性能優良的(de)的(de)非金屬材料(liao)或具有耐腐蝕(shi)特(te)性的(de)金屬材料(liao)）做集塵(chen)極，另一種是用(yong)通過噴水(shui)(shui)或溢流水(shui)(shui)形(xing)成導電(dian)水(shui)(shui)膜，利(li)用(yong)不導電(dian)的(de)非金屬材料(liao)做集塵(chen)極。
