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)除塵器主要有(you)兩種結構形式，一種是(shi)使用(yong)耐腐蝕(shi)(shi)導電(dian)(dian)材(cai)料(liao)(liao)（可以為導電(dian)(dian)性能優良的(de)的(de)非(fei)金(jin)屬材(cai)料(liao)(liao)或具(ju)有(you)耐腐蝕(shi)(shi)特性的(de)金(jin)屬材(cai)料(liao)(liao)）做集塵極(ji)，另一種是(shi)用(yong)通過(guo)噴水或溢流(liu)水形成導電(dian)(dian)水膜，利用(yong)不(bu)導電(dian)(dian)的(de)非(fei)金(jin)屬材(cai)料(liao)(liao)做集塵極(ji)。

濕(shi)式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器和與干式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器的收塵(chen)(chen)(chen)(chen)(chen)原理(li)相(xiang)同，都是靠(kao)高(gao)(gao)壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后(hou)的粉塵(chen)(chen)(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)場力(li)的作用下到(dao)達集(ji)塵(chen)(chen)(chen)(chen)(chen)板(ban)/管。干式電(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)(chen)器主要(yao)處理(li)含水(shui)很低的干氣體(ti)，濕(shi)式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器主要(yao)處理(li)含水(shui)較(jiao)高(gao)(gao)乃至飽和的濕(shi)氣體(ti)。在(zai)對(dui)集(ji)塵(chen)(chen)(chen)(chen)(chen)板(ban)/管上(shang)捕集(ji)到(dao)的粉塵(chen)(chen)(chen)(chen)(chen)清除(chu)(chu)方(fang)(fang)式上(shang)WESP與DESP有(you)較(jiao)大區別，干式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器一般采用機械振打(da)或聲(sheng)波(bo)清灰等方(fang)(fang)式清除(chu)(chu)電(dian)(dian)(dian)極(ji)上(shang)的積(ji)灰，而濕(shi)式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器則采用定期沖洗(xi)的方(fang)(fang)式，使粉塵(chen)(chen)(chen)(chen)(chen)隨著沖刷液的流(liu)動而清除(chu)(chu)。
