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)(dian)除塵器主要有兩種結構(gou)形式，一種是使用耐腐蝕導電(dian)(dian)(dian)材料(liao)（可以為導電(dian)(dian)(dian)性能優良的(de)(de)的(de)(de)非金屬材料(liao)或具(ju)有耐腐蝕特性的(de)(de)金屬材料(liao)）做(zuo)集塵極(ji)，另一種是用通過噴(pen)水或溢流水形成導電(dian)(dian)(dian)水膜，利用不導電(dian)(dian)(dian)的(de)(de)非金屬材料(liao)做(zuo)集塵極(ji)。

收塵(chen)原理

濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器和與(yu)干式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器的收塵(chen)原(yuan)理相同，都是靠高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉(fen)(fen)塵(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的粉(fen)(fen)塵(chen)在電(dian)(dian)(dian)場力的作用(yong)下到達(da)集(ji)塵(chen)板/管。干式(shi)(shi)電(dian)(dian)(dian)收塵(chen)器主(zhu)要處理含水很低(di)的干氣(qi)體，濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器主(zhu)要處理含水較高乃(nai)至飽和的濕氣(qi)體。在對(dui)集(ji)塵(chen)板/管上(shang)捕集(ji)到的粉(fen)(fen)塵(chen)清(qing)除(chu)(chu)方式(shi)(shi)上(shang)WESP與(yu)DESP有較大區別，干式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器一般采用(yong)機(ji)械振打或聲波清(qing)灰等方式(shi)(shi)清(qing)除(chu)(chu)電(dian)(dian)(dian)極上(shang)的積灰，而濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器則采用(yong)定(ding)期沖洗的方式(shi)(shi)，使粉(fen)(fen)塵(chen)隨著(zhu)沖刷液的流動而清(qing)除(chu)(chu)。
