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)(chen)器主要(yao)有兩種(zhong)結構(gou)形式，一種(zhong)是(shi)使(shi)用(yong)耐腐蝕(shi)導電材(cai)料(liao)（可以為導電性(xing)能(neng)優良的的非金屬材(cai)料(liao)或(huo)具有耐腐蝕(shi)特性(xing)的金屬材(cai)料(liao)）做(zuo)集(ji)塵(chen)(chen)極，另一種(zhong)是(shi)用(yong)通過噴(pen)水或(huo)溢流水形成(cheng)導電水膜，利用(yong)不導電的非金屬材(cai)料(liao)做(zuo)集(ji)塵(chen)(chen)極。

收塵原理

濕(shi)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)和與干(gan)(gan)(gan)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)的(de)收塵(chen)(chen)(chen)(chen)(chen)原理相同，都是靠高壓電(dian)(dian)(dian)暈(yun)放(fang)電(dian)(dian)(dian)使得(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后(hou)的(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場(chang)力的(de)作用下到達集塵(chen)(chen)(chen)(chen)(chen)板/管(guan)(guan)。干(gan)(gan)(gan)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)主要處(chu)理含水很低的(de)干(gan)(gan)(gan)氣體(ti)(ti)(ti)，濕(shi)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)主要處(chu)理含水較(jiao)高乃至(zhi)飽和的(de)濕(shi)氣體(ti)(ti)(ti)。在對(dui)集塵(chen)(chen)(chen)(chen)(chen)板/管(guan)(guan)上(shang)捕集到的(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)清除(chu)(chu)(chu)方(fang)式(shi)(shi)(shi)(shi)上(shang)WESP與DESP有(you)較(jiao)大區別，干(gan)(gan)(gan)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)一般采用機械(xie)振(zhen)打或聲波清灰(hui)等方(fang)式(shi)(shi)(shi)(shi)清除(chu)(chu)(chu)電(dian)(dian)(dian)極上(shang)的(de)積灰(hui)，而濕(shi)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)則采用定(ding)期沖洗的(de)方(fang)式(shi)(shi)(shi)(shi)，使粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)隨著沖刷液的(de)流(liu)動而清除(chu)(chu)(chu)。
