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)(chen)器主要有兩種(zhong)結構形式，一種(zhong)是(shi)(shi)使用(yong)耐腐(fu)蝕導(dao)電(dian)材(cai)料(liao)（可以為導(dao)電(dian)性能優良的的非金屬材(cai)料(liao)或(huo)具有耐腐(fu)蝕特性的金屬材(cai)料(liao)）做集塵(chen)(chen)極，另一種(zhong)是(shi)(shi)用(yong)通過(guo)噴水或(huo)溢流水形成導(dao)電(dian)水膜，利用(yong)不導(dao)電(dian)的非金屬材(cai)料(liao)做集塵(chen)(chen)極。

濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)和(he)與干式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)收塵(chen)(chen)(chen)(chen)原理相(xiang)同，都是靠高壓電(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)使得(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后(hou)的(de)粉塵(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場力的(de)作用(yong)下(xia)到(dao)達集塵(chen)(chen)(chen)(chen)板/管。干式(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)器(qi)主要(yao)處(chu)理含水很低的(de)干氣(qi)體，濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)主要(yao)處(chu)理含水較(jiao)(jiao)高乃至飽和(he)的(de)濕氣(qi)體。在對集塵(chen)(chen)(chen)(chen)板/管上捕集到(dao)的(de)粉塵(chen)(chen)(chen)(chen)清除(chu)方式(shi)上WESP與DESP有較(jiao)(jiao)大區別，干式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)一(yi)般采用(yong)機械(xie)振打或聲波(bo)清灰等方式(shi)清除(chu)電(dian)(dian)(dian)極上的(de)積灰，而(er)濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)則采用(yong)定期沖洗的(de)方式(shi)，使粉塵(chen)(chen)(chen)(chen)隨(sui)著沖刷(shua)液的(de)流動而(er)清除(chu)。
