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(shi)電除塵器主要有兩種(zhong)結(jie)構形式(shi)，一種(zhong)是使用耐(nai)腐(fu)蝕導(dao)電材料(liao)（可以為(wei)導(dao)電性能(neng)優良的的非(fei)金屬材料(liao)或具有耐(nai)腐(fu)蝕特(te)性的金屬材料(liao)）做集(ji)(ji)塵極(ji)，另一種(zhong)是用通過噴(pen)水(shui)或溢流(liu)水(shui)形成導(dao)電水(shui)膜，利用不導(dao)電的非(fei)金屬材料(liao)做集(ji)(ji)塵極(ji)。

收塵(chen)原理

濕式(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)和與干式(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)的(de)收(shou)塵(chen)(chen)原理(li)相同，都(dou)是(shi)靠高壓電(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)使得粉(fen)(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)(dian)后(hou)的(de)粉(fen)(fen)塵(chen)(chen)在電(dian)(dian)(dian)(dian)場(chang)力的(de)作(zuo)用(yong)(yong)下到達集塵(chen)(chen)板/管(guan)。干式(shi)電(dian)(dian)(dian)(dian)收(shou)塵(chen)(chen)器(qi)(qi)主要處理(li)含水很低的(de)干氣體(ti)，濕式(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)主要處理(li)含水較高乃至飽(bao)和的(de)濕氣體(ti)。在對集塵(chen)(chen)板/管(guan)上(shang)捕集到的(de)粉(fen)(fen)塵(chen)(chen)清除(chu)方(fang)式(shi)上(shang)WESP與DESP有較大區別，干式(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)一般采用(yong)(yong)機(ji)械振打或聲波清灰等方(fang)式(shi)清除(chu)電(dian)(dian)(dian)(dian)極上(shang)的(de)積灰，而(er)濕式(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)則采用(yong)(yong)定期(qi)沖(chong)洗的(de)方(fang)式(shi)，使粉(fen)(fen)塵(chen)(chen)隨(sui)著沖(chong)刷(shua)液的(de)流動而(er)清除(chu)。
