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)除塵器主要有(you)兩種(zhong)結(jie)構形(xing)式，一(yi)種(zhong)是使用(yong)耐腐蝕導(dao)電(dian)材(cai)料（可以(yi)為導(dao)電(dian)性能優良的(de)(de)的(de)(de)非(fei)金(jin)屬(shu)(shu)材(cai)料或具(ju)有(you)耐腐蝕特(te)性的(de)(de)金(jin)屬(shu)(shu)材(cai)料）做集(ji)(ji)塵極，另(ling)一(yi)種(zhong)是用(yong)通過噴(pen)水(shui)或溢(yi)流水(shui)形(xing)成導(dao)電(dian)水(shui)膜，利用(yong)不導(dao)電(dian)的(de)(de)非(fei)金(jin)屬(shu)(shu)材(cai)料做集(ji)(ji)塵極。

收塵原理

濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除塵(chen)器(qi)和與(yu)干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)除塵(chen)器(qi)的(de)收(shou)塵(chen)原理相同，都是(shi)靠(kao)高壓電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)使(shi)得粉塵(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)粉塵(chen)在電(dian)(dian)(dian)場力的(de)作用下到(dao)達集塵(chen)板/管(guan)。干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)收(shou)塵(chen)器(qi)主(zhu)要(yao)處(chu)(chu)理含(han)水(shui)很(hen)低的(de)干(gan)氣(qi)體(ti)(ti)，濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除塵(chen)器(qi)主(zhu)要(yao)處(chu)(chu)理含(han)水(shui)較(jiao)高乃(nai)至飽和的(de)濕(shi)氣(qi)體(ti)(ti)。在對集塵(chen)板/管(guan)上(shang)捕集到(dao)的(de)粉塵(chen)清(qing)除方(fang)式(shi)(shi)(shi)上(shang)WESP與(yu)DESP有較(jiao)大區別(bie)，干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)除塵(chen)器(qi)一般采(cai)用機械振(zhen)打或聲波清(qing)灰等方(fang)式(shi)(shi)(shi)清(qing)除電(dian)(dian)(dian)極上(shang)的(de)積灰，而濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除塵(chen)器(qi)則采(cai)用定(ding)期(qi)沖(chong)洗(xi)的(de)方(fang)式(shi)(shi)(shi)，使(shi)粉塵(chen)隨著沖(chong)刷液(ye)的(de)流動而清(qing)除。
