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)電除塵器(qi)主(zhu)要有兩種(zhong)結構形式(shi)，一(yi)種(zhong)是(shi)使(shi)用耐腐蝕導(dao)(dao)電材(cai)(cai)料(liao)（可(ke)以為導(dao)(dao)電性(xing)能優良(liang)的(de)(de)(de)的(de)(de)(de)非金(jin)屬材(cai)(cai)料(liao)或具有耐腐蝕特性(xing)的(de)(de)(de)金(jin)屬材(cai)(cai)料(liao)）做集塵極(ji)，另一(yi)種(zhong)是(shi)用通過噴水或溢(yi)流水形成導(dao)(dao)電水膜，利用不導(dao)(dao)電的(de)(de)(de)非金(jin)屬材(cai)(cai)料(liao)做集塵極(ji)。

收塵原理

濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)和與干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)收塵(chen)(chen)原理相同，都是靠高壓電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)使得粉塵(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)(de)粉塵(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)作(zuo)用下到達集塵(chen)(chen)板/管(guan)。干(gan)式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)器(qi)主要處(chu)理含(han)水很低的(de)(de)干(gan)氣(qi)體，濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)主要處(chu)理含(han)水較高乃(nai)至飽和的(de)(de)濕(shi)氣(qi)體。在對集塵(chen)(chen)板/管(guan)上捕(bu)集到的(de)(de)粉塵(chen)(chen)清(qing)除(chu)(chu)方式(shi)(shi)上WESP與DESP有(you)較大區別，干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)一般采(cai)(cai)用機械振(zhen)打或聲(sheng)波清(qing)灰等(deng)方式(shi)(shi)清(qing)除(chu)(chu)電(dian)(dian)(dian)極上的(de)(de)積灰，而濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)則采(cai)(cai)用定期(qi)沖(chong)洗的(de)(de)方式(shi)(shi)，使粉塵(chen)(chen)隨著沖(chong)刷液(ye)的(de)(de)流動而清(qing)除(chu)(chu)。
