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)(dian)除塵(chen)器主要(yao)有(you)(you)兩(liang)種結構(gou)形式，一種是使用(yong)耐腐(fu)蝕(shi)導電(dian)(dian)材(cai)料(liao)（可以為(wei)導電(dian)(dian)性能(neng)優良的(de)的(de)非(fei)金屬材(cai)料(liao)或具有(you)(you)耐腐(fu)蝕(shi)特性的(de)金屬材(cai)料(liao)）做(zuo)集(ji)塵(chen)極，另一種是用(yong)通過噴(pen)水(shui)或溢流水(shui)形成導電(dian)(dian)水(shui)膜，利用(yong)不導電(dian)(dian)的(de)非(fei)金屬材(cai)料(liao)做(zuo)集(ji)塵(chen)極。

收塵原理

濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)和與干式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)收塵(chen)(chen)(chen)(chen)(chen)原理相(xiang)同，都是靠(kao)高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使(shi)得粉塵(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)作用下到達集(ji)塵(chen)(chen)(chen)(chen)(chen)板/管(guan)。干式(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)(chen)器(qi)主要處(chu)理含水很低的(de)(de)干氣體(ti)，濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)主要處(chu)理含水較高乃至飽和的(de)(de)濕氣體(ti)。在對集(ji)塵(chen)(chen)(chen)(chen)(chen)板/管(guan)上捕(bu)集(ji)到的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)清(qing)除(chu)方(fang)式(shi)上WESP與DESP有較大區別，干式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)一般(ban)采(cai)用機械振打(da)或聲波清(qing)灰等(deng)方(fang)式(shi)清(qing)除(chu)電(dian)(dian)(dian)極上的(de)(de)積灰，而濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)則采(cai)用定(ding)期沖洗的(de)(de)方(fang)式(shi)，使(shi)粉塵(chen)(chen)(chen)(chen)(chen)隨著沖刷液的(de)(de)流動而清(qing)除(chu)。
