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(qi)主(zhu)要(yao)有(you)兩種結構(gou)形(xing)式，一種是使用耐(nai)腐蝕(shi)導(dao)電(dian)材(cai)料（可以為(wei)導(dao)電(dian)性(xing)能優良的(de)(de)的(de)(de)非(fei)金屬材(cai)料或具有(you)耐(nai)腐蝕(shi)特(te)性(xing)的(de)(de)金屬材(cai)料）做集(ji)塵極，另(ling)一種是用通過(guo)噴(pen)水(shui)或溢(yi)流(liu)水(shui)形(xing)成導(dao)電(dian)水(shui)膜，利用不導(dao)電(dian)的(de)(de)非(fei)金屬材(cai)料做集(ji)塵極。
