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(chu)塵(chen)器(qi)主(zhu)要有(you)兩種(zhong)結構形(xing)式，一(yi)(yi)種(zhong)是使用耐腐(fu)蝕導(dao)電材(cai)料（可以為導(dao)電性(xing)能優(you)良的的非(fei)(fei)金(jin)(jin)屬材(cai)料或具有(you)耐腐(fu)蝕特性(xing)的金(jin)(jin)屬材(cai)料）做集(ji)塵(chen)極，另一(yi)(yi)種(zhong)是用通(tong)過(guo)噴水(shui)(shui)或溢流水(shui)(shui)形(xing)成導(dao)電水(shui)(shui)膜，利用不導(dao)電的非(fei)(fei)金(jin)(jin)屬材(cai)料做集(ji)塵(chen)極。

收塵原理

濕(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)和(he)與干式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)收塵(chen)(chen)(chen)原(yuan)理(li)相(xiang)同，都是靠高壓(ya)電(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)使得粉塵(chen)(chen)(chen)荷(he)(he)電(dian)(dian)(dian)，荷(he)(he)電(dian)(dian)(dian)后的(de)(de)粉塵(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)場力的(de)(de)作(zuo)用下到(dao)(dao)達(da)集塵(chen)(chen)(chen)板(ban)/管(guan)(guan)。干式(shi)(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)器(qi)主要處理(li)含水(shui)很低(di)的(de)(de)干氣體，濕(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)主要處理(li)含水(shui)較(jiao)高乃(nai)至飽和(he)的(de)(de)濕(shi)(shi)氣體。在(zai)對集塵(chen)(chen)(chen)板(ban)/管(guan)(guan)上(shang)(shang)捕集到(dao)(dao)的(de)(de)粉塵(chen)(chen)(chen)清除(chu)方(fang)式(shi)(shi)(shi)上(shang)(shang)WESP與DESP有較(jiao)大區別，干式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)一般采用機(ji)械振打或聲(sheng)波清灰(hui)等(deng)方(fang)式(shi)(shi)(shi)清除(chu)電(dian)(dian)(dian)極上(shang)(shang)的(de)(de)積灰(hui)，而濕(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)則采用定期沖(chong)洗的(de)(de)方(fang)式(shi)(shi)(shi)，使粉塵(chen)(chen)(chen)隨著(zhu)沖(chong)刷液的(de)(de)流(liu)動而清除(chu)。
