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)(shi)電(dian)除塵器(qi)主要有兩種(zhong)結構(gou)形(xing)式(shi)(shi)，一種(zhong)是(shi)使用(yong)耐腐蝕(shi)導(dao)(dao)電(dian)材料（可(ke)以為(wei)導(dao)(dao)電(dian)性(xing)能優良的(de)(de)的(de)(de)非(fei)金屬材料或(huo)(huo)具有耐腐蝕(shi)特(te)性(xing)的(de)(de)金屬材料）做(zuo)集(ji)塵極(ji)，另一種(zhong)是(shi)用(yong)通過噴水(shui)(shui)或(huo)(huo)溢流(liu)水(shui)(shui)形(xing)成導(dao)(dao)電(dian)水(shui)(shui)膜(mo)，利用(yong)不導(dao)(dao)電(dian)的(de)(de)非(fei)金屬材料做(zuo)集(ji)塵極(ji)。

收(shou)塵(chen)原理

濕式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)和(he)與干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)的(de)收(shou)塵(chen)原理(li)相同，都(dou)是靠(kao)高壓電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)使得粉(fen)塵(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)粉(fen)塵(chen)在(zai)電(dian)(dian)(dian)場(chang)力的(de)作用(yong)下到達(da)集塵(chen)板(ban)/管。干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)收(shou)塵(chen)器(qi)(qi)主(zhu)要(yao)處理(li)含(han)水很低的(de)干(gan)(gan)氣(qi)體(ti)，濕式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)主(zhu)要(yao)處理(li)含(han)水較高乃至飽和(he)的(de)濕氣(qi)體(ti)。在(zai)對集塵(chen)板(ban)/管上(shang)捕集到的(de)粉(fen)塵(chen)清(qing)除(chu)方(fang)式(shi)(shi)上(shang)WESP與DESP有較大(da)區別，干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)一般(ban)采用(yong)機械振打(da)或(huo)聲波清(qing)灰等方(fang)式(shi)(shi)清(qing)除(chu)電(dian)(dian)(dian)極(ji)上(shang)的(de)積灰，而濕式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)則(ze)采用(yong)定期沖洗的(de)方(fang)式(shi)(shi)，使粉(fen)塵(chen)隨著沖刷液的(de)流動(dong)而清(qing)除(chu)。
