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(chen)器主(zhu)要有兩種(zhong)結(jie)構形式，一種(zhong)是(shi)使(shi)用耐(nai)(nai)腐蝕(shi)導電(dian)(dian)材料(liao)(liao)（可以為(wei)導電(dian)(dian)性能優良的的非金屬材料(liao)(liao)或具有耐(nai)(nai)腐蝕(shi)特性的金屬材料(liao)(liao)）做集塵(chen)極，另一種(zhong)是(shi)用通過噴水(shui)或溢流水(shui)形成導電(dian)(dian)水(shui)膜，利用不導電(dian)(dian)的非金屬材料(liao)(liao)做集塵(chen)極。

收塵原理

濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)和(he)與干式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)的(de)(de)(de)收(shou)塵(chen)(chen)原理相同，都是靠高(gao)壓電(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)使得粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)(de)(de)粉塵(chen)(chen)在(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用下到達集塵(chen)(chen)板/管。干式(shi)(shi)電(dian)(dian)(dian)(dian)收(shou)塵(chen)(chen)器(qi)(qi)主要(yao)處理含(han)水很低(di)的(de)(de)(de)干氣(qi)體(ti)，濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)主要(yao)處理含(han)水較(jiao)高(gao)乃(nai)至飽和(he)的(de)(de)(de)濕(shi)氣(qi)體(ti)。在(zai)對(dui)集塵(chen)(chen)板/管上(shang)捕集到的(de)(de)(de)粉塵(chen)(chen)清(qing)(qing)除(chu)(chu)(chu)方式(shi)(shi)上(shang)WESP與DESP有(you)較(jiao)大區別(bie)，干式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)一般采用機械振打或聲波清(qing)(qing)灰(hui)(hui)等方式(shi)(shi)清(qing)(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)(dian)極上(shang)的(de)(de)(de)積灰(hui)(hui)，而(er)濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)(qi)則(ze)采用定期沖洗的(de)(de)(de)方式(shi)(shi)，使粉塵(chen)(chen)隨著沖刷液的(de)(de)(de)流(liu)動(dong)而(er)清(qing)(qing)除(chu)(chu)(chu)。
