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(shi)式電除塵器主要有(you)兩種結構形(xing)式，一(yi)種是使(shi)用耐腐(fu)蝕(shi)導電材料（可以為導電性能優(you)良的(de)的(de)非(fei)金屬材料或(huo)具有(you)耐腐(fu)蝕(shi)特性的(de)金屬材料）做(zuo)集(ji)塵極，另一(yi)種是用通過噴水(shui)或(huo)溢流水(shui)形(xing)成(cheng)導電水(shui)膜，利用不導電的(de)非(fei)金屬材料做(zuo)集(ji)塵極。

濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器和與干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器的收塵(chen)(chen)(chen)(chen)原理相同，都是(shi)靠高壓(ya)電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的粉(fen)塵(chen)(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)場力的作用下到(dao)達(da)集塵(chen)(chen)(chen)(chen)板/管(guan)。干(gan)式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)器主要處理含(han)水很低的干(gan)氣體(ti)(ti)，濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器主要處理含(han)水較高乃至飽和的濕氣體(ti)(ti)。在(zai)對集塵(chen)(chen)(chen)(chen)板/管(guan)上(shang)(shang)捕(bu)集到(dao)的粉(fen)塵(chen)(chen)(chen)(chen)清(qing)(qing)除(chu)(chu)(chu)方(fang)式(shi)(shi)上(shang)(shang)WESP與DESP有(you)較大區別，干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器一般采(cai)用機械振打或聲波清(qing)(qing)灰等方(fang)式(shi)(shi)清(qing)(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)極(ji)上(shang)(shang)的積灰，而濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器則采(cai)用定期沖(chong)洗的方(fang)式(shi)(shi)，使粉(fen)塵(chen)(chen)(chen)(chen)隨(sui)著沖(chong)刷液的流(liu)動而清(qing)(qing)除(chu)(chu)(chu)。
