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)器主要(yao)有(you)(you)兩(liang)種(zhong)結構(gou)形式，一(yi)(yi)種(zhong)是使用耐(nai)腐(fu)蝕(shi)導電(dian)材料(liao)(liao)（可以為導電(dian)性(xing)能優良的的非金屬材料(liao)(liao)或具(ju)有(you)(you)耐(nai)腐(fu)蝕(shi)特性(xing)的金屬材料(liao)(liao)）做集塵(chen)極(ji)，另(ling)一(yi)(yi)種(zhong)是用通過(guo)噴水(shui)或溢流水(shui)形成導電(dian)水(shui)膜(mo)，利用不導電(dian)的非金屬材料(liao)(liao)做集塵(chen)極(ji)。

收(shou)塵原理

濕(shi)式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)和(he)與(yu)(yu)干式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)的收(shou)塵(chen)(chen)(chen)(chen)原理相同，都是靠高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的粉(fen)塵(chen)(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)場力(li)的作(zuo)用(yong)(yong)下到(dao)達(da)集(ji)塵(chen)(chen)(chen)(chen)板(ban)/管。干式(shi)電(dian)(dian)(dian)收(shou)塵(chen)(chen)(chen)(chen)器(qi)主(zhu)要(yao)處(chu)理含(han)水很低(di)的干氣體(ti)，濕(shi)式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)主(zhu)要(yao)處(chu)理含(han)水較(jiao)(jiao)高乃(nai)至飽和(he)的濕(shi)氣體(ti)。在(zai)對集(ji)塵(chen)(chen)(chen)(chen)板(ban)/管上(shang)捕集(ji)到(dao)的粉(fen)塵(chen)(chen)(chen)(chen)清(qing)(qing)除(chu)(chu)(chu)方式(shi)上(shang)WESP與(yu)(yu)DESP有較(jiao)(jiao)大區(qu)別，干式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)一般采用(yong)(yong)機械振打或(huo)聲波清(qing)(qing)灰等方式(shi)清(qing)(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)極(ji)上(shang)的積灰，而濕(shi)式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)則采用(yong)(yong)定期(qi)沖洗的方式(shi)，使粉(fen)塵(chen)(chen)(chen)(chen)隨著沖刷液(ye)的流動而清(qing)(qing)除(chu)(chu)(chu)。
