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)除塵器主要有兩(liang)種結構形式，一種是使(shi)用(yong)耐腐蝕導電(dian)(dian)(dian)材料(liao)（可以為導電(dian)(dian)(dian)性能優良(liang)的(de)(de)的(de)(de)非金(jin)屬(shu)材料(liao)或具有耐腐蝕特性的(de)(de)金(jin)屬(shu)材料(liao)）做集(ji)塵極，另一種是用(yong)通過噴(pen)水或溢流水形成導電(dian)(dian)(dian)水膜(mo)，利用(yong)不(bu)導電(dian)(dian)(dian)的(de)(de)非金(jin)屬(shu)材料(liao)做集(ji)塵極。

濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)和與(yu)干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)的(de)(de)收(shou)塵(chen)(chen)原理相同，都是靠(kao)高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得(de)粉(fen)塵(chen)(chen)荷(he)(he)電(dian)(dian)(dian)，荷(he)(he)電(dian)(dian)(dian)后的(de)(de)粉(fen)塵(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)作用下(xia)到達集(ji)塵(chen)(chen)板(ban)/管。干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)收(shou)塵(chen)(chen)器(qi)(qi)主要處理含水很(hen)低的(de)(de)干(gan)(gan)氣體(ti)，濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)主要處理含水較高乃至飽和的(de)(de)濕氣體(ti)。在對集(ji)塵(chen)(chen)板(ban)/管上(shang)捕集(ji)到的(de)(de)粉(fen)塵(chen)(chen)清(qing)除(chu)(chu)(chu)方式(shi)(shi)上(shang)WESP與(yu)DESP有(you)較大區別，干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)一般(ban)采用機(ji)械振(zhen)打或聲(sheng)波清(qing)灰等(deng)方式(shi)(shi)清(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)極上(shang)的(de)(de)積灰，而(er)濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)則采用定期沖洗的(de)(de)方式(shi)(shi)，使粉(fen)塵(chen)(chen)隨(sui)著沖刷液的(de)(de)流動而(er)清(qing)除(chu)(chu)(chu)。
