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(qi)主要有(you)兩種(zhong)結構(gou)形式，一種(zhong)是(shi)使用耐(nai)腐蝕導(dao)電(dian)材(cai)料（可以為導(dao)電(dian)性能優良的(de)的(de)非金屬材(cai)料或具有(you)耐(nai)腐蝕特性的(de)金屬材(cai)料）做(zuo)集(ji)塵極，另一種(zhong)是(shi)用通過(guo)噴(pen)水(shui)或溢流水(shui)形成(cheng)導(dao)電(dian)水(shui)膜，利(li)用不導(dao)電(dian)的(de)非金屬材(cai)料做(zuo)集(ji)塵極。

收塵原理

濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器和(he)與干式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器的(de)收(shou)塵(chen)原理相同，都(dou)是靠高壓電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)使(shi)得粉塵(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后(hou)的(de)粉塵(chen)在(zai)電(dian)(dian)(dian)場力的(de)作(zuo)用下到(dao)達集塵(chen)板(ban)/管(guan)。干式(shi)(shi)電(dian)(dian)(dian)收(shou)塵(chen)器主要處理含水(shui)很(hen)低的(de)干氣體(ti)，濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器主要處理含水(shui)較高乃至飽和(he)的(de)濕(shi)氣體(ti)。在(zai)對集塵(chen)板(ban)/管(guan)上(shang)捕集到(dao)的(de)粉塵(chen)清(qing)(qing)(qing)除(chu)(chu)方式(shi)(shi)上(shang)WESP與DESP有較大區(qu)別，干式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器一(yi)般采用機(ji)械(xie)振打或聲波清(qing)(qing)(qing)灰等方式(shi)(shi)清(qing)(qing)(qing)除(chu)(chu)電(dian)(dian)(dian)極上(shang)的(de)積灰，而(er)濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器則(ze)采用定(ding)期沖(chong)洗的(de)方式(shi)(shi)，使(shi)粉塵(chen)隨(sui)著沖(chong)刷(shua)液(ye)的(de)流動而(er)清(qing)(qing)(qing)除(chu)(chu)。
