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)(dian)除(chu)塵器主要有兩種(zhong)結構形(xing)(xing)式，一(yi)種(zhong)是使用耐腐(fu)蝕(shi)導電(dian)(dian)(dian)材料（可(ke)以為導電(dian)(dian)(dian)性(xing)(xing)能(neng)優良的(de)的(de)非金(jin)屬材料或具(ju)有耐腐(fu)蝕(shi)特性(xing)(xing)的(de)金(jin)屬材料）做(zuo)(zuo)集(ji)塵極，另一(yi)種(zhong)是用通(tong)過噴水或溢流水形(xing)(xing)成導電(dian)(dian)(dian)水膜，利(li)用不導電(dian)(dian)(dian)的(de)非金(jin)屬材料做(zuo)(zuo)集(ji)塵極。

收塵原理

濕式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)器和(he)(he)與干式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)收塵(chen)原理相(xiang)同，都是靠高壓(ya)電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使(shi)得粉(fen)塵(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的(de)(de)粉(fen)塵(chen)在電(dian)(dian)(dian)場(chang)力(li)的(de)(de)作用(yong)下到(dao)達集(ji)塵(chen)板(ban)/管。干式(shi)(shi)(shi)電(dian)(dian)(dian)收塵(chen)器主(zhu)要處理含(han)水很(hen)低的(de)(de)干氣體，濕式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)器主(zhu)要處理含(han)水較高乃(nai)至飽(bao)和(he)(he)的(de)(de)濕氣體。在對集(ji)塵(chen)板(ban)/管上(shang)(shang)捕集(ji)到(dao)的(de)(de)粉(fen)塵(chen)清除(chu)方(fang)式(shi)(shi)(shi)上(shang)(shang)WESP與DESP有(you)較大區別，干式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)器一(yi)般采用(yong)機械振(zhen)打或聲波清灰(hui)等方(fang)式(shi)(shi)(shi)清除(chu)電(dian)(dian)(dian)極(ji)上(shang)(shang)的(de)(de)積(ji)灰(hui)，而濕式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)器則(ze)采用(yong)定期(qi)沖洗的(de)(de)方(fang)式(shi)(shi)(shi)，使(shi)粉(fen)塵(chen)隨(sui)著沖刷液的(de)(de)流(liu)動(dong)而清除(chu)。
