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(chen)器(qi)主要有(you)兩種結構形式，一種是使用耐(nai)腐(fu)蝕導(dao)(dao)電(dian)材(cai)料（可以為導(dao)(dao)電(dian)性(xing)(xing)能優良的(de)的(de)非金(jin)屬(shu)材(cai)料或(huo)具(ju)有(you)耐(nai)腐(fu)蝕特性(xing)(xing)的(de)金(jin)屬(shu)材(cai)料）做(zuo)集塵(chen)極(ji)，另一種是用通過(guo)噴水(shui)或(huo)溢流(liu)水(shui)形成導(dao)(dao)電(dian)水(shui)膜(mo)，利(li)用不導(dao)(dao)電(dian)的(de)非金(jin)屬(shu)材(cai)料做(zuo)集塵(chen)極(ji)。

收塵(chen)原理
