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)(dian)除(chu)塵(chen)器主要有(you)兩種結(jie)構形(xing)式，一種是使用耐(nai)腐(fu)(fu)蝕(shi)(shi)導(dao)電(dian)(dian)材(cai)(cai)料（可以(yi)為(wei)導(dao)電(dian)(dian)性能優良(liang)的(de)的(de)非(fei)金(jin)屬材(cai)(cai)料或具有(you)耐(nai)腐(fu)(fu)蝕(shi)(shi)特性的(de)金(jin)屬材(cai)(cai)料）做(zuo)集(ji)(ji)塵(chen)極，另一種是用通過(guo)噴(pen)水或溢流水形(xing)成導(dao)電(dian)(dian)水膜，利用不導(dao)電(dian)(dian)的(de)非(fei)金(jin)屬材(cai)(cai)料做(zuo)集(ji)(ji)塵(chen)極。
