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(you)兩種結構形(xing)式(shi)，一(yi)種是(shi)使用(yong)耐腐蝕(shi)導(dao)電(dian)(dian)材(cai)(cai)料（可以為(wei)導(dao)電(dian)(dian)性(xing)能優良的的非金屬材(cai)(cai)料或具有(you)耐腐蝕(shi)特性(xing)的金屬材(cai)(cai)料）做(zuo)集塵極(ji)，另一(yi)種是(shi)用(yong)通過噴(pen)水(shui)或溢流水(shui)形(xing)成導(dao)電(dian)(dian)水(shui)膜，利(li)用(yong)不導(dao)電(dian)(dian)的非金屬材(cai)(cai)料做(zuo)集塵極(ji)。
