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)(dian)除塵器主要(yao)有(you)兩種(zhong)結構形式，一種(zhong)是使用(yong)(yong)耐(nai)腐蝕(shi)導(dao)電(dian)(dian)材(cai)(cai)料(liao)（可以為導(dao)電(dian)(dian)性能優良(liang)的的非金屬(shu)材(cai)(cai)料(liao)或具有(you)耐(nai)腐蝕(shi)特性的金屬(shu)材(cai)(cai)料(liao)）做(zuo)集(ji)塵極，另一種(zhong)是用(yong)(yong)通過噴(pen)水或溢流水形成導(dao)電(dian)(dian)水膜，利(li)用(yong)(yong)不(bu)導(dao)電(dian)(dian)的非金屬(shu)材(cai)(cai)料(liao)做(zuo)集(ji)塵極。

收塵(chen)原理

濕式(shi)(shi)(shi)(shi)(shi)電(dian)(dian)除塵(chen)(chen)器(qi)(qi)和與干(gan)(gan)式(shi)(shi)(shi)(shi)(shi)電(dian)(dian)除塵(chen)(chen)器(qi)(qi)的(de)(de)收塵(chen)(chen)原理(li)(li)相同，都是(shi)靠高(gao)壓電(dian)(dian)暈放電(dian)(dian)使得(de)粉塵(chen)(chen)荷電(dian)(dian)，荷電(dian)(dian)后(hou)的(de)(de)粉塵(chen)(chen)在電(dian)(dian)場力的(de)(de)作用(yong)下到達集塵(chen)(chen)板/管。干(gan)(gan)式(shi)(shi)(shi)(shi)(shi)電(dian)(dian)收塵(chen)(chen)器(qi)(qi)主要處理(li)(li)含(han)水(shui)(shui)很低的(de)(de)干(gan)(gan)氣體(ti)(ti)，濕式(shi)(shi)(shi)(shi)(shi)電(dian)(dian)除塵(chen)(chen)器(qi)(qi)主要處理(li)(li)含(han)水(shui)(shui)較高(gao)乃至飽和的(de)(de)濕氣體(ti)(ti)。在對集塵(chen)(chen)板/管上捕集到的(de)(de)粉塵(chen)(chen)清(qing)除方式(shi)(shi)(shi)(shi)(shi)上WESP與DESP有較大(da)區別，干(gan)(gan)式(shi)(shi)(shi)(shi)(shi)電(dian)(dian)除塵(chen)(chen)器(qi)(qi)一般采(cai)用(yong)機械振打或聲波清(qing)灰等方式(shi)(shi)(shi)(shi)(shi)清(qing)除電(dian)(dian)極上的(de)(de)積灰，而(er)濕式(shi)(shi)(shi)(shi)(shi)電(dian)(dian)除塵(chen)(chen)器(qi)(qi)則采(cai)用(yong)定期沖(chong)洗的(de)(de)方式(shi)(shi)(shi)(shi)(shi)，使粉塵(chen)(chen)隨著(zhu)沖(chong)刷液的(de)(de)流動而(er)清(qing)除。
