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)除塵器主要有(you)兩(liang)種(zhong)(zhong)結(jie)構(gou)形式，一種(zhong)(zhong)是(shi)使用(yong)耐腐蝕(shi)導(dao)電(dian)(dian)材(cai)料(liao)(liao)（可以(yi)為導(dao)電(dian)(dian)性能優良的(de)(de)的(de)(de)非金(jin)屬材(cai)料(liao)(liao)或具有(you)耐腐蝕(shi)特性的(de)(de)金(jin)屬材(cai)料(liao)(liao)）做(zuo)集塵極(ji)，另一種(zhong)(zhong)是(shi)用(yong)通過(guo)噴(pen)水(shui)(shui)或溢流水(shui)(shui)形成導(dao)電(dian)(dian)水(shui)(shui)膜，利用(yong)不(bu)導(dao)電(dian)(dian)的(de)(de)非金(jin)屬材(cai)料(liao)(liao)做(zuo)集塵極(ji)。

收塵(chen)原理

濕(shi)式(shi)(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器和(he)(he)與(yu)干式(shi)(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)(de)(de)(de)收塵(chen)(chen)(chen)原理相同，都是靠(kao)高壓電(dian)(dian)暈(yun)放(fang)電(dian)(dian)使得(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)，荷電(dian)(dian)后的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)在電(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)作用(yong)(yong)下(xia)到(dao)達集(ji)塵(chen)(chen)(chen)板/管。干式(shi)(shi)(shi)電(dian)(dian)收塵(chen)(chen)(chen)器主要(yao)處理含水很低的(de)(de)(de)(de)(de)干氣體(ti)，濕(shi)式(shi)(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器主要(yao)處理含水較高乃至(zhi)飽和(he)(he)的(de)(de)(de)(de)(de)濕(shi)氣體(ti)。在對集(ji)塵(chen)(chen)(chen)板/管上捕(bu)集(ji)到(dao)的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)清除(chu)方式(shi)(shi)(shi)上WESP與(yu)DESP有較大區(qu)別，干式(shi)(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器一般(ban)采用(yong)(yong)機械振(zhen)打或聲波清灰等(deng)方式(shi)(shi)(shi)清除(chu)電(dian)(dian)極(ji)上的(de)(de)(de)(de)(de)積灰，而濕(shi)式(shi)(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器則采用(yong)(yong)定(ding)期沖(chong)洗的(de)(de)(de)(de)(de)方式(shi)(shi)(shi)，使粉塵(chen)(chen)(chen)隨著(zhu)沖(chong)刷液(ye)的(de)(de)(de)(de)(de)流動而清除(chu)。
