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)除塵器主要有(you)兩種結構形式，一種是使(shi)用耐腐蝕(shi)導(dao)電(dian)材(cai)(cai)(cai)料（可以(yi)為導(dao)電(dian)性能優(you)良的(de)的(de)非金屬材(cai)(cai)(cai)料或具有(you)耐腐蝕(shi)特性的(de)金屬材(cai)(cai)(cai)料）做集塵極，另(ling)一種是用通過噴水或溢流水形成導(dao)電(dian)水膜，利用不導(dao)電(dian)的(de)非金屬材(cai)(cai)(cai)料做集塵極。
