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(shi)電(dian)除塵(chen)器主要(yao)有(you)(you)兩種(zhong)結(jie)構(gou)形(xing)式(shi)，一(yi)種(zhong)是使用(yong)耐腐蝕導(dao)電(dian)材(cai)料(liao)(liao)（可以為導(dao)電(dian)性能優良的的非金(jin)屬(shu)(shu)材(cai)料(liao)(liao)或(huo)具(ju)有(you)(you)耐腐蝕特性的金(jin)屬(shu)(shu)材(cai)料(liao)(liao)）做集塵(chen)極(ji)，另一(yi)種(zhong)是用(yong)通過噴(pen)水或(huo)溢流水形(xing)成(cheng)導(dao)電(dian)水膜(mo)，利用(yong)不導(dao)電(dian)的非金(jin)屬(shu)(shu)材(cai)料(liao)(liao)做集塵(chen)極(ji)。

收塵原理

濕式(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)和(he)與(yu)干(gan)式(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)收(shou)塵(chen)(chen)(chen)原理相同，都是靠高(gao)壓電(dian)(dian)暈放電(dian)(dian)使(shi)得粉塵(chen)(chen)(chen)荷(he)(he)電(dian)(dian)，荷(he)(he)電(dian)(dian)后的(de)粉塵(chen)(chen)(chen)在電(dian)(dian)場力的(de)作用下到(dao)達集塵(chen)(chen)(chen)板/管(guan)。干(gan)式(shi)(shi)電(dian)(dian)收(shou)塵(chen)(chen)(chen)器(qi)主要處(chu)理含水(shui)(shui)很低的(de)干(gan)氣(qi)體，濕式(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)主要處(chu)理含水(shui)(shui)較(jiao)高(gao)乃至飽(bao)和(he)的(de)濕氣(qi)體。在對集塵(chen)(chen)(chen)板/管(guan)上捕(bu)集到(dao)的(de)粉塵(chen)(chen)(chen)清(qing)除(chu)(chu)(chu)方式(shi)(shi)上WESP與(yu)DESP有較(jiao)大區別，干(gan)式(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)一般采用機械振打或聲波清(qing)灰等方式(shi)(shi)清(qing)除(chu)(chu)(chu)電(dian)(dian)極上的(de)積(ji)灰，而(er)濕式(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)則(ze)采用定期(qi)沖(chong)洗的(de)方式(shi)(shi)，使(shi)粉塵(chen)(chen)(chen)隨著沖(chong)刷液的(de)流動而(er)清(qing)除(chu)(chu)(chu)。
