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)除塵器主要有(you)兩種(zhong)結構形式，一種(zhong)是使用(yong)耐腐(fu)蝕導(dao)電(dian)(dian)材(cai)(cai)料（可(ke)以為導(dao)電(dian)(dian)性能優良的(de)(de)的(de)(de)非金(jin)屬(shu)(shu)材(cai)(cai)料或具有(you)耐腐(fu)蝕特性的(de)(de)金(jin)屬(shu)(shu)材(cai)(cai)料）做集(ji)塵極，另一種(zhong)是用(yong)通過(guo)噴水或溢流水形成導(dao)電(dian)(dian)水膜，利用(yong)不導(dao)電(dian)(dian)的(de)(de)非金(jin)屬(shu)(shu)材(cai)(cai)料做集(ji)塵極。

收塵原理

濕(shi)式電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)和與(yu)干式電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)收塵(chen)(chen)(chen)(chen)原理(li)相同，都是靠高(gao)壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使(shi)得粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)粉(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場力的(de)作用下到(dao)達集(ji)塵(chen)(chen)(chen)(chen)板/管。干式電(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)器(qi)主(zhu)要處(chu)理(li)含水(shui)很低的(de)干氣(qi)體(ti)(ti)，濕(shi)式電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)主(zhu)要處(chu)理(li)含水(shui)較高(gao)乃至(zhi)飽和的(de)濕(shi)氣(qi)體(ti)(ti)。在對集(ji)塵(chen)(chen)(chen)(chen)板/管上捕集(ji)到(dao)的(de)粉(fen)塵(chen)(chen)(chen)(chen)清(qing)除方式上WESP與(yu)DESP有較大區別，干式電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)一般采(cai)用機械振打或(huo)聲(sheng)波清(qing)灰(hui)等方式清(qing)除電(dian)(dian)(dian)極上的(de)積灰(hui)，而濕(shi)式電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)則(ze)采(cai)用定期沖洗的(de)方式，使(shi)粉(fen)塵(chen)(chen)(chen)(chen)隨著沖刷液(ye)的(de)流動(dong)而清(qing)除。
