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(dian)(dian)除塵(chen)器(qi)主要(yao)有兩種(zhong)結構(gou)形式(shi)，一種(zhong)是使用耐腐蝕導(dao)(dao)電(dian)(dian)材料(liao)（可以為導(dao)(dao)電(dian)(dian)性(xing)能優良的(de)的(de)非(fei)金屬(shu)材料(liao)或具有耐腐蝕特性(xing)的(de)金屬(shu)材料(liao)）做(zuo)集塵(chen)極(ji)，另一種(zhong)是用通過噴水或溢流水形成導(dao)(dao)電(dian)(dian)水膜，利(li)用不導(dao)(dao)電(dian)(dian)的(de)非(fei)金屬(shu)材料(liao)做(zuo)集塵(chen)極(ji)。

收塵(chen)原理

濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)和(he)與干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)收塵(chen)(chen)(chen)(chen)(chen)(chen)原理相同，都是靠高壓電(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)使得粉塵(chen)(chen)(chen)(chen)(chen)(chen)荷(he)(he)電(dian)(dian)(dian)，荷(he)(he)電(dian)(dian)(dian)后的(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場力的(de)作用(yong)下到達集塵(chen)(chen)(chen)(chen)(chen)(chen)板/管。干(gan)式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)主(zhu)要(yao)處(chu)理含(han)水(shui)(shui)很低(di)的(de)干(gan)氣(qi)體，濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)主(zhu)要(yao)處(chu)理含(han)水(shui)(shui)較(jiao)高乃至飽和(he)的(de)濕氣(qi)體。在對集塵(chen)(chen)(chen)(chen)(chen)(chen)板/管上捕集到的(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)清(qing)除(chu)(chu)(chu)方式(shi)(shi)上WESP與DESP有較(jiao)大區別(bie)，干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)一(yi)般采用(yong)機械(xie)振打或聲波(bo)清(qing)灰等方式(shi)(shi)清(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)極上的(de)積灰，而(er)濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)則采用(yong)定期沖洗的(de)方式(shi)(shi)，使粉塵(chen)(chen)(chen)(chen)(chen)(chen)隨著沖刷(shua)液的(de)流動而(er)清(qing)除(chu)(chu)(chu)。
