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)(shi)電(dian)(dian)(dian)除塵器(qi)主要有兩(liang)種結構形(xing)式(shi)(shi)，一種是使用耐(nai)腐(fu)蝕導(dao)電(dian)(dian)(dian)材料(liao)（可以為導(dao)電(dian)(dian)(dian)性(xing)能優良的的非金屬材料(liao)或具有耐(nai)腐(fu)蝕特性(xing)的金屬材料(liao)）做(zuo)集塵極，另一種是用通過噴水(shui)或溢流(liu)水(shui)形(xing)成導(dao)電(dian)(dian)(dian)水(shui)膜，利用不導(dao)電(dian)(dian)(dian)的非金屬材料(liao)做(zuo)集塵極。

收塵(chen)原理

濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)和(he)與干(gan)式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)的(de)(de)(de)收塵(chen)(chen)(chen)(chen)(chen)原理相同，都是(shi)靠(kao)高(gao)壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)用(yong)下到(dao)達集塵(chen)(chen)(chen)(chen)(chen)板(ban)/管。干(gan)式(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)主(zhu)要處理含水很(hen)低的(de)(de)(de)干(gan)氣體，濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)主(zhu)要處理含水較(jiao)(jiao)高(gao)乃至飽和(he)的(de)(de)(de)濕氣體。在對集塵(chen)(chen)(chen)(chen)(chen)板(ban)/管上捕集到(dao)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)清除(chu)方(fang)式(shi)上WESP與DESP有較(jiao)(jiao)大區別，干(gan)式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)一般(ban)采(cai)用(yong)機械振打或聲(sheng)波清灰等方(fang)式(shi)清除(chu)電(dian)(dian)(dian)極上的(de)(de)(de)積灰，而濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)則采(cai)用(yong)定期(qi)沖(chong)洗的(de)(de)(de)方(fang)式(shi)，使粉(fen)塵(chen)(chen)(chen)(chen)(chen)隨著沖(chong)刷液的(de)(de)(de)流動而清除(chu)。
