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(qi)主要(yao)有兩種結構形(xing)式，一(yi)種是使用(yong)耐腐(fu)蝕(shi)導(dao)電(dian)材(cai)料（可以為(wei)導(dao)電(dian)性(xing)(xing)能優良的(de)(de)的(de)(de)非金屬(shu)材(cai)料或(huo)具有耐腐(fu)蝕(shi)特性(xing)(xing)的(de)(de)金屬(shu)材(cai)料）做(zuo)集塵(chen)極(ji)(ji)，另一(yi)種是用(yong)通過(guo)噴水或(huo)溢流(liu)水形(xing)成導(dao)電(dian)水膜，利用(yong)不導(dao)電(dian)的(de)(de)非金屬(shu)材(cai)料做(zuo)集塵(chen)極(ji)(ji)。

收塵原理

濕式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)(qi)(qi)和與干式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)(qi)(qi)的(de)(de)收塵(chen)原(yuan)理相(xiang)同，都(dou)是靠高壓(ya)電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使(shi)得粉塵(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后(hou)的(de)(de)粉塵(chen)在電(dian)(dian)(dian)場力的(de)(de)作用下到達(da)集塵(chen)板/管。干式(shi)電(dian)(dian)(dian)收塵(chen)器(qi)(qi)(qi)主(zhu)要(yao)處(chu)理含(han)水很低的(de)(de)干氣體(ti)(ti)，濕式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)(qi)(qi)主(zhu)要(yao)處(chu)理含(han)水較(jiao)高乃至飽和的(de)(de)濕氣體(ti)(ti)。在對集塵(chen)板/管上(shang)捕集到的(de)(de)粉塵(chen)清除(chu)(chu)方式(shi)上(shang)WESP與DESP有較(jiao)大區(qu)別(bie)，干式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)(qi)(qi)一般采用機械振打或聲波清灰等方式(shi)清除(chu)(chu)電(dian)(dian)(dian)極上(shang)的(de)(de)積灰，而濕式(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)(qi)(qi)則(ze)采用定期沖(chong)洗(xi)的(de)(de)方式(shi)，使(shi)粉塵(chen)隨著沖(chong)刷液的(de)(de)流動而清除(chu)(chu)。
