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)兩種(zhong)結構形式，一(yi)種(zhong)是使(shi)用(yong)耐腐蝕(shi)導(dao)電(dian)(dian)材料(liao)(liao)（可以為導(dao)電(dian)(dian)性能優良的(de)的(de)非金屬(shu)(shu)材料(liao)(liao)或(huo)具(ju)有(you)耐腐蝕(shi)特性的(de)金屬(shu)(shu)材料(liao)(liao)）做集(ji)塵極，另一(yi)種(zhong)是用(yong)通過噴水(shui)(shui)或(huo)溢(yi)流水(shui)(shui)形成導(dao)電(dian)(dian)水(shui)(shui)膜，利用(yong)不導(dao)電(dian)(dian)的(de)非金屬(shu)(shu)材料(liao)(liao)做集(ji)塵極。

收(shou)塵(chen)原理

濕式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)和與干(gan)式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)的(de)收(shou)塵(chen)(chen)(chen)(chen)原理(li)(li)相同，都是靠高壓電(dian)(dian)暈放(fang)電(dian)(dian)使(shi)得粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)，荷(he)電(dian)(dian)后的(de)粉(fen)塵(chen)(chen)(chen)(chen)在(zai)電(dian)(dian)場力的(de)作用下到達集塵(chen)(chen)(chen)(chen)板(ban)/管。干(gan)式(shi)(shi)電(dian)(dian)收(shou)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)主(zhu)要處理(li)(li)含(han)(han)水很低的(de)干(gan)氣體(ti)，濕式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)主(zhu)要處理(li)(li)含(han)(han)水較(jiao)高乃至(zhi)飽和的(de)濕氣體(ti)。在(zai)對集塵(chen)(chen)(chen)(chen)板(ban)/管上捕集到的(de)粉(fen)塵(chen)(chen)(chen)(chen)清(qing)除(chu)(chu)方式(shi)(shi)上WESP與DESP有較(jiao)大區別，干(gan)式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)一般采(cai)用機(ji)械振打(da)或(huo)聲波清(qing)灰等方式(shi)(shi)清(qing)除(chu)(chu)電(dian)(dian)極(ji)上的(de)積灰，而(er)濕式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)(qi)則采(cai)用定期沖(chong)洗(xi)的(de)方式(shi)(shi)，使(shi)粉(fen)塵(chen)(chen)(chen)(chen)隨(sui)著沖(chong)刷液(ye)的(de)流(liu)動而(er)清(qing)除(chu)(chu)。
