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)電除塵(chen)(chen)器(qi)主要有兩種結構形(xing)式(shi)，一種是(shi)使(shi)用耐腐蝕導電材料(liao)(liao)（可以為導電性(xing)(xing)能優良的(de)(de)的(de)(de)非(fei)金屬材料(liao)(liao)或具有耐腐蝕特(te)性(xing)(xing)的(de)(de)金屬材料(liao)(liao)）做集塵(chen)(chen)極，另一種是(shi)用通過噴水(shui)或溢流水(shui)形(xing)成導電水(shui)膜(mo)，利用不導電的(de)(de)非(fei)金屬材料(liao)(liao)做集塵(chen)(chen)極。

收塵原理

濕式(shi)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)和(he)與干式(shi)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)收(shou)塵(chen)(chen)(chen)(chen)(chen)原理(li)相同，都是靠高壓(ya)電(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)使(shi)得粉塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)粉塵(chen)(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)(dian)場力(li)的(de)作用(yong)(yong)下(xia)到(dao)達(da)集塵(chen)(chen)(chen)(chen)(chen)板/管(guan)。干式(shi)電(dian)(dian)(dian)(dian)收(shou)塵(chen)(chen)(chen)(chen)(chen)器(qi)主(zhu)要(yao)處理(li)含水很低的(de)干氣體(ti)，濕式(shi)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)主(zhu)要(yao)處理(li)含水較高乃至(zhi)飽和(he)的(de)濕氣體(ti)。在對(dui)集塵(chen)(chen)(chen)(chen)(chen)板/管(guan)上捕集到(dao)的(de)粉塵(chen)(chen)(chen)(chen)(chen)清(qing)(qing)除方式(shi)上WESP與DESP有較大區別，干式(shi)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)一般采用(yong)(yong)機械(xie)振打或聲波清(qing)(qing)灰等方式(shi)清(qing)(qing)除電(dian)(dian)(dian)(dian)極(ji)上的(de)積灰，而(er)濕式(shi)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)則采用(yong)(yong)定(ding)期(qi)沖(chong)洗的(de)方式(shi)，使(shi)粉塵(chen)(chen)(chen)(chen)(chen)隨著沖(chong)刷液(ye)的(de)流(liu)動而(er)清(qing)(qing)除。
