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)電除塵器主要(yao)有兩種結(jie)構形式(shi)，一(yi)種是(shi)使用耐腐(fu)蝕導(dao)電材(cai)料（可以為導(dao)電性(xing)能優良的的非(fei)金屬材(cai)料或(huo)具(ju)有耐腐(fu)蝕特(te)性(xing)的金屬材(cai)料）做集塵極(ji)，另(ling)一(yi)種是(shi)用通(tong)過噴(pen)水(shui)或(huo)溢流水(shui)形成(cheng)導(dao)電水(shui)膜，利用不導(dao)電的非(fei)金屬材(cai)料做集塵極(ji)。

收(shou)塵(chen)原理

濕式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)和與干(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)收(shou)塵(chen)(chen)原理相同，都是靠高壓電(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)使(shi)得粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)(dian)后的(de)(de)(de)粉塵(chen)(chen)在(zai)電(dian)(dian)(dian)(dian)場力(li)的(de)(de)(de)作用(yong)下到達集(ji)塵(chen)(chen)板/管(guan)。干(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)收(shou)塵(chen)(chen)器(qi)主要(yao)處理含水很(hen)低的(de)(de)(de)干(gan)氣(qi)體(ti)，濕式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)主要(yao)處理含水較(jiao)高乃至飽和的(de)(de)(de)濕氣(qi)體(ti)。在(zai)對(dui)集(ji)塵(chen)(chen)板/管(guan)上(shang)捕集(ji)到的(de)(de)(de)粉塵(chen)(chen)清(qing)除(chu)(chu)方(fang)式(shi)(shi)上(shang)WESP與DESP有較(jiao)大區(qu)別(bie)，干(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)一(yi)般采用(yong)機械振打或聲波清(qing)灰等(deng)方(fang)式(shi)(shi)清(qing)除(chu)(chu)電(dian)(dian)(dian)(dian)極上(shang)的(de)(de)(de)積灰，而(er)濕式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)則采用(yong)定期沖(chong)洗(xi)的(de)(de)(de)方(fang)式(shi)(shi)，使(shi)粉塵(chen)(chen)隨著沖(chong)刷液的(de)(de)(de)流(liu)動而(er)清(qing)除(chu)(chu)。
