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(chu)塵(chen)器(qi)主要有兩種結(jie)構(gou)形(xing)式，一種是(shi)使用耐(nai)(nai)腐(fu)蝕導(dao)電(dian)(dian)材料(liao)(liao)（可以為(wei)導(dao)電(dian)(dian)性能優良的(de)(de)的(de)(de)非金屬材料(liao)(liao)或具(ju)有耐(nai)(nai)腐(fu)蝕特(te)性的(de)(de)金屬材料(liao)(liao)）做(zuo)集(ji)塵(chen)極，另一種是(shi)用通過噴水或溢流(liu)水形(xing)成(cheng)導(dao)電(dian)(dian)水膜，利用不導(dao)電(dian)(dian)的(de)(de)非金屬材料(liao)(liao)做(zuo)集(ji)塵(chen)極。

收塵原(yuan)理

濕(shi)式(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)和(he)與干式(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的收(shou)塵(chen)(chen)(chen)原理相同，都是靠高壓電(dian)(dian)暈放電(dian)(dian)使得粉塵(chen)(chen)(chen)荷電(dian)(dian)，荷電(dian)(dian)后的粉塵(chen)(chen)(chen)在(zai)電(dian)(dian)場(chang)力的作用(yong)下到達集塵(chen)(chen)(chen)板/管(guan)。干式(shi)電(dian)(dian)收(shou)塵(chen)(chen)(chen)器(qi)主(zhu)要處(chu)理含(han)水(shui)很(hen)低的干氣(qi)體(ti)，濕(shi)式(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)主(zhu)要處(chu)理含(han)水(shui)較高乃至(zhi)飽和(he)的濕(shi)氣(qi)體(ti)。在(zai)對(dui)集塵(chen)(chen)(chen)板/管(guan)上捕集到的粉塵(chen)(chen)(chen)清(qing)除(chu)(chu)方式(shi)上WESP與DESP有較大區(qu)別，干式(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)一般采(cai)用(yong)機械振打或聲波(bo)清(qing)灰等方式(shi)清(qing)除(chu)(chu)電(dian)(dian)極上的積灰，而濕(shi)式(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)則采(cai)用(yong)定期(qi)沖(chong)洗的方式(shi)，使粉塵(chen)(chen)(chen)隨著沖(chong)刷液的流(liu)動而清(qing)除(chu)(chu)。
