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。

濕式電除塵(chen)器主要有(you)兩種(zhong)結構形式，一(yi)(yi)種(zhong)是使(shi)用耐腐蝕(shi)導(dao)電材料(liao)（可以為導(dao)電性能優良的(de)的(de)非(fei)(fei)金(jin)(jin)屬(shu)材料(liao)或(huo)具有(you)耐腐蝕(shi)特性的(de)金(jin)(jin)屬(shu)材料(liao)）做集塵(chen)極，另一(yi)(yi)種(zhong)是用通(tong)過(guo)噴水(shui)或(huo)溢(yi)流水(shui)形成(cheng)導(dao)電水(shui)膜，利用不導(dao)電的(de)非(fei)(fei)金(jin)(jin)屬(shu)材料(liao)做集塵(chen)極。

收塵(chen)原理

濕式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器和與干式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的收塵(chen)(chen)原理(li)相同，都是靠(kao)高壓(ya)電(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)使(shi)得粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)(dian)后的粉(fen)塵(chen)(chen)在電(dian)(dian)(dian)(dian)場力(li)的作用下(xia)到達集塵(chen)(chen)板/管。干式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)收塵(chen)(chen)器主要(yao)處(chu)理(li)含水很低的干氣(qi)體(ti)，濕式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器主要(yao)處(chu)理(li)含水較高乃至飽和的濕氣(qi)體(ti)。在對集塵(chen)(chen)板/管上捕集到的粉(fen)塵(chen)(chen)清(qing)除(chu)方式(shi)(shi)(shi)上WESP與DESP有較大區別，干式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器一般采用機械振(zhen)打或(huo)聲波(bo)清(qing)灰等(deng)方式(shi)(shi)(shi)清(qing)除(chu)電(dian)(dian)(dian)(dian)極上的積(ji)灰，而(er)濕式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器則采用定期(qi)沖洗的方式(shi)(shi)(shi)，使(shi)粉(fen)塵(chen)(chen)隨(sui)著沖刷液的流動而(er)清(qing)除(chu)。
