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)除塵(chen)器主(zhu)要(yao)有(you)兩(liang)種(zhong)結構形式(shi)，一(yi)種(zhong)是使用耐(nai)腐蝕導(dao)電(dian)材料(liao)(liao)（可(ke)以(yi)為(wei)導(dao)電(dian)性能優良的(de)的(de)非(fei)(fei)金屬材料(liao)(liao)或具(ju)有(you)耐(nai)腐蝕特性的(de)金屬材料(liao)(liao)）做(zuo)集塵(chen)極，另一(yi)種(zhong)是用通過噴水或溢流(liu)水形成導(dao)電(dian)水膜(mo)，利用不導(dao)電(dian)的(de)非(fei)(fei)金屬材料(liao)(liao)做(zuo)集塵(chen)極。

收塵(chen)原理

濕(shi)式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器和(he)與(yu)干(gan)(gan)(gan)式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器的(de)收塵(chen)(chen)(chen)(chen)原理相同，都是靠高(gao)壓電(dian)(dian)暈放電(dian)(dian)使(shi)得粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)，荷電(dian)(dian)后的(de)粉(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)場力的(de)作用(yong)下到達集(ji)塵(chen)(chen)(chen)(chen)板/管。干(gan)(gan)(gan)式(shi)(shi)電(dian)(dian)收塵(chen)(chen)(chen)(chen)器主(zhu)要處理含水(shui)很低的(de)干(gan)(gan)(gan)氣(qi)(qi)體，濕(shi)式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器主(zhu)要處理含水(shui)較(jiao)高(gao)乃至飽和(he)的(de)濕(shi)氣(qi)(qi)體。在對集(ji)塵(chen)(chen)(chen)(chen)板/管上(shang)(shang)捕集(ji)到的(de)粉(fen)塵(chen)(chen)(chen)(chen)清(qing)除(chu)(chu)方(fang)式(shi)(shi)上(shang)(shang)WESP與(yu)DESP有較(jiao)大區別，干(gan)(gan)(gan)式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器一般采用(yong)機械(xie)振打(da)或聲波(bo)清(qing)灰等方(fang)式(shi)(shi)清(qing)除(chu)(chu)電(dian)(dian)極上(shang)(shang)的(de)積灰，而濕(shi)式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器則(ze)采用(yong)定期沖(chong)(chong)洗(xi)的(de)方(fang)式(shi)(shi)，使(shi)粉(fen)塵(chen)(chen)(chen)(chen)隨著沖(chong)(chong)刷(shua)液的(de)流動而清(qing)除(chu)(chu)。
