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(shi)電除塵器主(zhu)要有(you)兩種(zhong)結(jie)構(gou)形式(shi)，一種(zhong)是使用耐腐蝕導(dao)電材(cai)料（可以為(wei)導(dao)電性能優(you)良的(de)的(de)非(fei)金(jin)屬材(cai)料或(huo)具有(you)耐腐蝕特性的(de)金(jin)屬材(cai)料）做(zuo)集塵極，另一種(zhong)是用通過噴水或(huo)溢流水形成導(dao)電水膜，利用不(bu)導(dao)電的(de)非(fei)金(jin)屬材(cai)料做(zuo)集塵極。

收塵原理

濕(shi)(shi)式(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器和與(yu)干(gan)式(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)收塵(chen)(chen)原理相同，都是靠高壓電(dian)(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)(dian)使得粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)(de)粉塵(chen)(chen)在電(dian)(dian)(dian)(dian)場力的(de)(de)作用(yong)下到達集(ji)塵(chen)(chen)板/管。干(gan)式(shi)電(dian)(dian)(dian)(dian)收塵(chen)(chen)器主(zhu)要處(chu)理含(han)(han)水(shui)很低的(de)(de)干(gan)氣體(ti)，濕(shi)(shi)式(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器主(zhu)要處(chu)理含(han)(han)水(shui)較高乃至飽和的(de)(de)濕(shi)(shi)氣體(ti)。在對集(ji)塵(chen)(chen)板/管上(shang)捕集(ji)到的(de)(de)粉塵(chen)(chen)清除(chu)方式(shi)上(shang)WESP與(yu)DESP有較大區(qu)別，干(gan)式(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器一般(ban)采(cai)用(yong)機械振打或聲波(bo)清灰(hui)(hui)等方式(shi)清除(chu)電(dian)(dian)(dian)(dian)極上(shang)的(de)(de)積灰(hui)(hui)，而濕(shi)(shi)式(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器則(ze)采(cai)用(yong)定期沖洗(xi)的(de)(de)方式(shi)，使粉塵(chen)(chen)隨(sui)著沖刷(shua)液的(de)(de)流動(dong)而清除(chu)。
