XWD型臥式靜電除塵器是眾多除塵器當中的一種，臥式靜電除塵器是以靜電凈化法來收捕廢氣中的粉塵的設備，其主要是讓含塵氣體進人氣刺叭時，含塵氣體受到氣流分布板以及折流板的調整后，使氣流能較均勻地進人電場。

臥式靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)凈(jing)化法來(lai)收(shou)捕廢氣(qi)(qi)(qi)(qi)中的(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)，它的(de)凈(jing)化工作上要是依(yi)靠電(dian)(dian)(dian)(dian)暈極(ji)和沉淀兩個系統(tong)來(lai)完成的(de)，當含塵(chen)(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)進(jin)(jin)人(ren)氣(qi)(qi)(qi)(qi)刺(ci)叭時，含塵(chen)(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)(qi)(qi)流(liu)(liu)分(fen)布板以及折流(liu)(liu)板的(de)調整后，使氣(qi)(qi)(qi)(qi)流(liu)(liu)能較(jiao)均勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場。在(zai)橫斷面擴大的(de)作用下(xia)(xia)(xia)，氣(qi)(qi)(qi)(qi)流(liu)(liu)速(su)度迅速(su)降低，其中有(you)些(xie)較(jiao)重的(de)塵(chen)(chen)(chen)(chen)(chen)(chen)粒便(bian)失去速(su)度而(er)沉降下(xia)(xia)(xia)來(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)含塵(chen)(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)通(tong)人(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)暈現象(xiang)，使氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)中存在(zai)大量的(de)電(dian)(dian)(dian)(dian)子和離子，這些(xie)電(dian)(dian)(dian)(dian)子和離子與進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)結合起(qi)來(lai)，使塵(chen)(chen)(chen)(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)場力的(de)作用下(xia)(xia)(xia)趨向本設備(bei)陽極(ji)(正極(ji)、本設備(bei)采用負高壓制(zhi))和陰極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分(fen)別沉積(ji)在(zai)相應的(de)電(dian)(dian)(dian)(dian)極(ji)上，通(tong)過設備(bei)陰陽極(ji)振打(da)(da)系統(tong)的(de)振打(da)(da)，使沉積(ji)在(zai)陰陽電(dian)(dian)(dian)(dian)極(ji)上的(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)振落，進(jin)(jin)人(ren)集(ji)灰(hui)斗(dou) 通(tong)過排灰(hui)裝置放出，回收(shou)有(you)物料，被)凈(jing)化的(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)排入大氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)工作(zuo)原(yuan)理是利(li)用(yong)高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)離，氣流中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用(yong)下與氣流分離。負(fu)極(ji)由(you)不同(tong)斷面形狀(zhuang)的(de)(de)金(jin)屬(shu)導(dao)線制(zhi)成(cheng)(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同(tong)幾何(he)形狀(zhuang)的(de)(de)金(jin)屬(shu)板(ban)制(zhi)成(cheng)(cheng)，叫(jiao)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設備構(gou)造和煙氣流速等三(san)個因素的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)是評價(jia)導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指(zhi)標，它對(dui)除(chu)(chu)塵(chen)(chen)(chen)(chen)效率有直接(jie)的(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)過低，塵(chen)(chen)(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重(zhong)返氣流。比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)過高，到達(da)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)層之(zhi)間形成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會產生(sheng)局(ju)部(bu)擊穿(chuan)和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成(cheng)(cheng)除(chu)(chu)塵(chen)(chen)(chen)(chen)效率下降(jiang)。

電(dian)(dian)(dian)除塵(chen)(chen)器的基(ji)本原理是利用(yong)電(dian)(dian)(dian)力捕集煙氣(qi)中的粉(fen)塵(chen)(chen)，主要包括以下四個相互有(you)關的物理過程: (1) 氣(qi)體的電(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)(dian)極移動(dong)。(4) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)(chen)的捕集。
