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。

濕式電除塵器主要有兩種結構形(xing)式，一種是使用耐(nai)腐蝕(shi)導(dao)電材料(liao)(liao)（可以(yi)為導(dao)電性能(neng)優良(liang)的(de)(de)的(de)(de)非金(jin)屬材料(liao)(liao)或具(ju)有耐(nai)腐蝕(shi)特性的(de)(de)金(jin)屬材料(liao)(liao)）做集塵極(ji)，另一種是用通過(guo)噴水(shui)或溢流水(shui)形(xing)成導(dao)電水(shui)膜，利用不導(dao)電的(de)(de)非金(jin)屬材料(liao)(liao)做集塵極(ji)。

收塵原理

濕式電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器和與干式電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器的收塵(chen)(chen)(chen)原理(li)相同，都是(shi)靠高(gao)壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使得粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后(hou)的粉塵(chen)(chen)(chen)在電(dian)(dian)(dian)(dian)場力的作用(yong)下到(dao)達集(ji)(ji)塵(chen)(chen)(chen)板/管(guan)。干式電(dian)(dian)(dian)(dian)收塵(chen)(chen)(chen)器主要(yao)處理(li)含水很低的干氣(qi)體，濕式電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器主要(yao)處理(li)含水較(jiao)高(gao)乃至飽和的濕氣(qi)體。在對集(ji)(ji)塵(chen)(chen)(chen)板/管(guan)上捕集(ji)(ji)到(dao)的粉塵(chen)(chen)(chen)清(qing)除(chu)(chu)(chu)方(fang)(fang)式上WESP與DESP有(you)較(jiao)大區(qu)別，干式電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器一般(ban)采用(yong)機械(xie)振打或聲波清(qing)灰(hui)等方(fang)(fang)式清(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)(dian)極上的積灰(hui)，而濕式電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器則采用(yong)定期(qi)沖(chong)洗的方(fang)(fang)式，使粉塵(chen)(chen)(chen)隨著沖(chong)刷液的流動而清(qing)除(chu)(chu)(chu)。
