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)(dian)除塵器主要有兩種(zhong)結(jie)構形式(shi)，一種(zhong)是(shi)使用耐腐蝕導(dao)電(dian)(dian)材(cai)(cai)料(liao)（可以為(wei)導(dao)電(dian)(dian)性(xing)能優(you)良的(de)的(de)非金(jin)(jin)屬材(cai)(cai)料(liao)或具有耐腐蝕特性(xing)的(de)金(jin)(jin)屬材(cai)(cai)料(liao)）做(zuo)集塵極，另一種(zhong)是(shi)用通過噴(pen)水(shui)或溢流水(shui)形成導(dao)電(dian)(dian)水(shui)膜，利用不導(dao)電(dian)(dian)的(de)非金(jin)(jin)屬材(cai)(cai)料(liao)做(zuo)集塵極。

收塵原理

濕(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)和與干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)(de)收塵(chen)(chen)原理(li)相同(tong)，都是靠高(gao)壓電(dian)(dian)(dian)暈(yun)放(fang)電(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)(de)(de)粉(fen)塵(chen)(chen)在(zai)電(dian)(dian)(dian)場力的(de)(de)(de)作用(yong)下到(dao)達集塵(chen)(chen)板(ban)(ban)/管。干(gan)式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)器(qi)主(zhu)要(yao)處理(li)含(han)水很低的(de)(de)(de)干(gan)氣體(ti)(ti)，濕(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)主(zhu)要(yao)處理(li)含(han)水較高(gao)乃(nai)至(zhi)飽(bao)和的(de)(de)(de)濕(shi)(shi)氣體(ti)(ti)。在(zai)對集塵(chen)(chen)板(ban)(ban)/管上捕集到(dao)的(de)(de)(de)粉(fen)塵(chen)(chen)清(qing)除(chu)方(fang)式(shi)(shi)上WESP與DESP有較大區別，干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)一般采(cai)用(yong)機械振打或聲波(bo)清(qing)灰等方(fang)式(shi)(shi)清(qing)除(chu)電(dian)(dian)(dian)極上的(de)(de)(de)積灰，而濕(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)則采(cai)用(yong)定(ding)期沖洗的(de)(de)(de)方(fang)式(shi)(shi)，使粉(fen)塵(chen)(chen)隨著沖刷液的(de)(de)(de)流動而清(qing)除(chu)。
