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)除塵器主要有兩種(zhong)結構形式，一種(zhong)是使用耐腐蝕(shi)導(dao)(dao)電(dian)材(cai)料(liao)（可以為導(dao)(dao)電(dian)性能優良(liang)的的非金(jin)屬材(cai)料(liao)或(huo)具有耐腐蝕(shi)特性的金(jin)屬材(cai)料(liao)）做(zuo)(zuo)集(ji)塵極(ji)(ji)，另一種(zhong)是用通過噴水或(huo)溢流水形成導(dao)(dao)電(dian)水膜(mo)，利(li)用不導(dao)(dao)電(dian)的非金(jin)屬材(cai)料(liao)做(zuo)(zuo)集(ji)塵極(ji)(ji)。

濕式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器和與干式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器的(de)收塵(chen)(chen)原理(li)(li)相同，都是靠高壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使(shi)得粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)粉(fen)塵(chen)(chen)在電(dian)(dian)(dian)(dian)場力的(de)作用下到達集(ji)(ji)塵(chen)(chen)板(ban)/管。干式(shi)電(dian)(dian)(dian)(dian)收塵(chen)(chen)器主要處理(li)(li)含水很低的(de)干氣體(ti)(ti)，濕式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器主要處理(li)(li)含水較高乃至(zhi)飽和的(de)濕氣體(ti)(ti)。在對集(ji)(ji)塵(chen)(chen)板(ban)/管上捕集(ji)(ji)到的(de)粉(fen)塵(chen)(chen)清(qing)除(chu)(chu)方(fang)式(shi)上WESP與DESP有較大區別，干式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器一般采用機械振(zhen)打或聲波清(qing)灰等方(fang)式(shi)清(qing)除(chu)(chu)電(dian)(dian)(dian)(dian)極上的(de)積灰，而濕式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器則采用定(ding)期沖(chong)洗的(de)方(fang)式(shi)，使(shi)粉(fen)塵(chen)(chen)隨著沖(chong)刷液的(de)流動而清(qing)除(chu)(chu)。
