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)(dian)(dian)除塵器(qi)主要有兩種結構形式，一(yi)種是使用(yong)(yong)耐腐蝕(shi)導電(dian)(dian)(dian)(dian)材(cai)料（可以為導電(dian)(dian)(dian)(dian)性能優(you)良的(de)(de)的(de)(de)非金(jin)屬材(cai)料或(huo)具(ju)有耐腐蝕(shi)特(te)性的(de)(de)金(jin)屬材(cai)料）做集(ji)塵極，另一(yi)種是用(yong)(yong)通過(guo)噴水(shui)(shui)或(huo)溢流水(shui)(shui)形成導電(dian)(dian)(dian)(dian)水(shui)(shui)膜，利用(yong)(yong)不(bu)導電(dian)(dian)(dian)(dian)的(de)(de)非金(jin)屬材(cai)料做集(ji)塵極。

收(shou)塵原理

濕式(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)和與干(gan)式(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)收塵(chen)(chen)(chen)原理相同，都(dou)是(shi)靠高(gao)壓電(dian)(dian)暈(yun)放(fang)電(dian)(dian)使(shi)得粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)，荷(he)電(dian)(dian)后的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)在電(dian)(dian)場(chang)力的(de)(de)(de)作用下(xia)到達集塵(chen)(chen)(chen)板/管。干(gan)式(shi)電(dian)(dian)收塵(chen)(chen)(chen)器(qi)主(zhu)要處理含水很(hen)低的(de)(de)(de)干(gan)氣體(ti)，濕式(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)主(zhu)要處理含水較(jiao)高(gao)乃至飽和的(de)(de)(de)濕氣體(ti)。在對集塵(chen)(chen)(chen)板/管上捕集到的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)清(qing)除(chu)方(fang)式(shi)上WESP與DESP有較(jiao)大(da)區(qu)別，干(gan)式(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)一般采用機械(xie)振打(da)或聲波清(qing)灰等方(fang)式(shi)清(qing)除(chu)電(dian)(dian)極上的(de)(de)(de)積灰，而濕式(shi)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)則采用定期沖洗的(de)(de)(de)方(fang)式(shi)，使(shi)粉(fen)塵(chen)(chen)(chen)隨著沖刷液的(de)(de)(de)流動而清(qing)除(chu)。
