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)器主要有(you)兩種結構(gou)形式，一種是使用(yong)耐(nai)腐蝕導電(dian)材料(liao)（可以為導電(dian)性能優(you)良的(de)的(de)非金(jin)屬(shu)材料(liao)或具有(you)耐(nai)腐蝕特性的(de)金(jin)屬(shu)材料(liao)）做(zuo)集塵(chen)極，另一種是用(yong)通過噴水(shui)或溢流水(shui)形成導電(dian)水(shui)膜，利用(yong)不(bu)導電(dian)的(de)非金(jin)屬(shu)材料(liao)做(zuo)集塵(chen)極。

收塵原理

濕(shi)(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器和與干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器的(de)(de)收塵(chen)(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(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)(de)粉(fen)塵(chen)(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)作用(yong)下到達集塵(chen)(chen)(chen)板/管。干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)器主要(yao)處(chu)理含水(shui)很低的(de)(de)干(gan)氣體，濕(shi)(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器主要(yao)處(chu)理含水(shui)較高(gao)乃(nai)至(zhi)飽和的(de)(de)濕(shi)(shi)(shi)氣體。在對集塵(chen)(chen)(chen)板/管上捕集到的(de)(de)粉(fen)塵(chen)(chen)(chen)清(qing)除(chu)(chu)(chu)方(fang)式(shi)(shi)(shi)上WESP與DESP有較大區別，干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器一般采用(yong)機(ji)械振打或聲(sheng)波清(qing)灰等方(fang)式(shi)(shi)(shi)清(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)極(ji)上的(de)(de)積灰，而(er)濕(shi)(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器則(ze)采用(yong)定(ding)期沖洗的(de)(de)方(fang)式(shi)(shi)(shi)，使粉(fen)塵(chen)(chen)(chen)隨著沖刷液(ye)的(de)(de)流動而(er)清(qing)除(chu)(chu)(chu)。
