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(shi)式(shi)電(dian)除塵(chen)器主要(yao)有(you)兩種結構(gou)形式(shi)，一(yi)種是使用(yong)耐腐(fu)蝕(shi)導電(dian)材料(liao)（可以為導電(dian)性(xing)能優良的(de)(de)的(de)(de)非金(jin)屬材料(liao)或具有(you)耐腐(fu)蝕(shi)特性(xing)的(de)(de)金(jin)屬材料(liao)）做(zuo)集塵(chen)極，另(ling)一(yi)種是用(yong)通過噴水或溢(yi)流水形成(cheng)導電(dian)水膜，利用(yong)不導電(dian)的(de)(de)非金(jin)屬材料(liao)做(zuo)集塵(chen)極。

濕(shi)式電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)和與干(gan)式電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)的(de)(de)收(shou)塵(chen)(chen)原理相同，都是靠(kao)高(gao)壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)(de)粉塵(chen)(chen)在電(dian)(dian)(dian)場力(li)的(de)(de)作用(yong)下到達集(ji)(ji)塵(chen)(chen)板(ban)/管。干(gan)式電(dian)(dian)(dian)收(shou)塵(chen)(chen)器(qi)(qi)(qi)主(zhu)(zhu)要(yao)處(chu)理含(han)水(shui)很低的(de)(de)干(gan)氣體，濕(shi)式電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)主(zhu)(zhu)要(yao)處(chu)理含(han)水(shui)較高(gao)乃至飽(bao)和的(de)(de)濕(shi)氣體。在對集(ji)(ji)塵(chen)(chen)板(ban)/管上捕集(ji)(ji)到的(de)(de)粉塵(chen)(chen)清(qing)除(chu)(chu)(chu)方式上WESP與DESP有較大區(qu)別，干(gan)式電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)一(yi)般采用(yong)機械(xie)振打或聲波清(qing)灰等方式清(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)極上的(de)(de)積(ji)灰，而(er)濕(shi)式電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)(qi)則(ze)采用(yong)定期沖(chong)(chong)洗的(de)(de)方式，使粉塵(chen)(chen)隨(sui)著沖(chong)(chong)刷(shua)液的(de)(de)流動而(er)清(qing)除(chu)(chu)(chu)。
