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)除塵(chen)器主要有(you)兩種(zhong)(zhong)(zhong)結構(gou)形式，一種(zhong)(zhong)(zhong)是使用耐(nai)腐蝕導(dao)電(dian)材(cai)料(liao)（可(ke)以為導(dao)電(dian)性(xing)能優(you)良的的非金屬(shu)(shu)材(cai)料(liao)或具有(you)耐(nai)腐蝕特性(xing)的金屬(shu)(shu)材(cai)料(liao)）做(zuo)(zuo)集(ji)塵(chen)極(ji)，另(ling)一種(zhong)(zhong)(zhong)是用通過噴水或溢流水形成導(dao)電(dian)水膜，利用不導(dao)電(dian)的非金屬(shu)(shu)材(cai)料(liao)做(zuo)(zuo)集(ji)塵(chen)極(ji)。

收(shou)塵原理(li)

濕式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)和與(yu)干式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)收(shou)塵(chen)(chen)(chen)原(yuan)理相同，都(dou)是靠(kao)高壓(ya)電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)粉塵(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)場(chang)力的(de)作(zuo)用下到達集塵(chen)(chen)(chen)板/管。干式(shi)(shi)電(dian)(dian)(dian)收(shou)塵(chen)(chen)(chen)器(qi)主要處理含水(shui)很低的(de)干氣(qi)體(ti)，濕式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)主要處理含水(shui)較高乃至飽和的(de)濕氣(qi)體(ti)。在(zai)對集塵(chen)(chen)(chen)板/管上(shang)(shang)捕集到的(de)粉塵(chen)(chen)(chen)清(qing)除(chu)方式(shi)(shi)上(shang)(shang)WESP與(yu)DESP有較大區別，干式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)一般采用機械(xie)振打或聲波清(qing)灰等方式(shi)(shi)清(qing)除(chu)電(dian)(dian)(dian)極上(shang)(shang)的(de)積灰，而(er)(er)濕式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)則采用定期沖洗的(de)方式(shi)(shi)，使粉塵(chen)(chen)(chen)隨(sui)著沖刷液(ye)的(de)流動(dong)而(er)(er)清(qing)除(chu)。
