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。

濕式電除塵(chen)器(qi)主(zhu)要(yao)有(you)兩種結構形式，一(yi)種是(shi)使用耐腐(fu)蝕導電材料(liao)（可(ke)以為導電性能優良(liang)的的非(fei)金(jin)屬(shu)(shu)材料(liao)或具(ju)有(you)耐腐(fu)蝕特性的金(jin)屬(shu)(shu)材料(liao)）做集塵(chen)極，另一(yi)種是(shi)用通過噴水或溢流水形成導電水膜，利用不導電的非(fei)金(jin)屬(shu)(shu)材料(liao)做集塵(chen)極。

收塵原理

濕式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)和(he)與(yu)(yu)干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)收塵(chen)(chen)原理(li)相同，都是靠高壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使(shi)得粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后(hou)的(de)(de)粉(fen)塵(chen)(chen)在電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用(yong)下到達(da)集(ji)塵(chen)(chen)板/管。干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)收塵(chen)(chen)器(qi)主要處(chu)理(li)含水(shui)很低的(de)(de)干(gan)(gan)氣(qi)體，濕式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)主要處(chu)理(li)含水(shui)較高乃至飽和(he)的(de)(de)濕氣(qi)體。在對集(ji)塵(chen)(chen)板/管上捕(bu)集(ji)到的(de)(de)粉(fen)塵(chen)(chen)清除(chu)(chu)(chu)方(fang)(fang)式(shi)(shi)上WESP與(yu)(yu)DESP有較大區別，干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)一般采用(yong)機(ji)械振(zhen)打或聲波清灰等(deng)方(fang)(fang)式(shi)(shi)清除(chu)(chu)(chu)電(dian)(dian)(dian)(dian)極上的(de)(de)積灰，而濕式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)則(ze)采用(yong)定(ding)期沖洗的(de)(de)方(fang)(fang)式(shi)(shi)，使(shi)粉(fen)塵(chen)(chen)隨著(zhu)沖刷液的(de)(de)流動而清除(chu)(chu)(chu)。
