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)兩種結構形式，一(yi)(yi)種是使(shi)用耐腐(fu)蝕導(dao)電(dian)材(cai)(cai)料（可以(yi)為導(dao)電(dian)性(xing)能優(you)良的的非(fei)(fei)金屬材(cai)(cai)料或具(ju)有(you)耐腐(fu)蝕特性(xing)的金屬材(cai)(cai)料）做集塵(chen)極，另一(yi)(yi)種是用通過噴水(shui)或溢(yi)流水(shui)形成(cheng)導(dao)電(dian)水(shui)膜，利用不導(dao)電(dian)的非(fei)(fei)金屬材(cai)(cai)料做集塵(chen)極。

收塵(chen)原理

濕(shi)式(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)和與干(gan)(gan)式(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)的(de)(de)收塵(chen)(chen)(chen)原(yuan)理相同，都是靠高(gao)壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使(shi)得粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后(hou)的(de)(de)粉塵(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)(dian)場力(li)的(de)(de)作(zuo)用下到達集(ji)塵(chen)(chen)(chen)板/管(guan)。干(gan)(gan)式(shi)電(dian)(dian)(dian)(dian)收塵(chen)(chen)(chen)器(qi)(qi)主要(yao)處理含水很低的(de)(de)干(gan)(gan)氣(qi)體，濕(shi)式(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)主要(yao)處理含水較高(gao)乃(nai)至飽和的(de)(de)濕(shi)氣(qi)體。在(zai)對集(ji)塵(chen)(chen)(chen)板/管(guan)上(shang)捕集(ji)到的(de)(de)粉塵(chen)(chen)(chen)清除(chu)方式(shi)上(shang)WESP與DESP有較大(da)區(qu)別，干(gan)(gan)式(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)一般采用機械振打(da)或聲波清灰等方式(shi)清除(chu)電(dian)(dian)(dian)(dian)極上(shang)的(de)(de)積灰，而濕(shi)式(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)則采用定(ding)期沖(chong)洗的(de)(de)方式(shi)，使(shi)粉塵(chen)(chen)(chen)隨著沖(chong)刷液的(de)(de)流動而清除(chu)。
