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(shi)電(dian)除塵器主(zhu)要有兩種結構形式(shi)，一種是(shi)使用(yong)耐腐蝕(shi)導(dao)(dao)電(dian)材(cai)料（可以為(wei)導(dao)(dao)電(dian)性能優良的(de)的(de)非(fei)金屬材(cai)料或具有耐腐蝕(shi)特(te)性的(de)金屬材(cai)料）做集(ji)塵極(ji)，另一種是(shi)用(yong)通過噴水或溢流水形成導(dao)(dao)電(dian)水膜，利用(yong)不(bu)導(dao)(dao)電(dian)的(de)非(fei)金屬材(cai)料做集(ji)塵極(ji)。

濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)和與(yu)(yu)干式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)的(de)收塵(chen)(chen)原理相同，都是靠高壓電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)使(shi)得粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的(de)粉塵(chen)(chen)在電(dian)(dian)(dian)場力的(de)作用(yong)下到(dao)達集(ji)塵(chen)(chen)板/管(guan)。干式(shi)電(dian)(dian)(dian)收塵(chen)(chen)器(qi)(qi)主(zhu)要(yao)(yao)處理含水很低的(de)干氣(qi)體(ti)(ti)，濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)主(zhu)要(yao)(yao)處理含水較高乃至飽和的(de)濕氣(qi)體(ti)(ti)。在對集(ji)塵(chen)(chen)板/管(guan)上(shang)捕集(ji)到(dao)的(de)粉塵(chen)(chen)清(qing)除(chu)方式(shi)上(shang)WESP與(yu)(yu)DESP有較大區別，干式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)一般采用(yong)機(ji)械振打或聲波(bo)清(qing)灰等方式(shi)清(qing)除(chu)電(dian)(dian)(dian)極上(shang)的(de)積灰，而(er)濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)則(ze)采用(yong)定期沖洗的(de)方式(shi)，使(shi)粉塵(chen)(chen)隨著(zhu)沖刷(shua)液的(de)流(liu)動(dong)而(er)清(qing)除(chu)。
