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(wo)式靜電(dian)(dian)(dian)除塵器是(shi)以靜電(dian)(dian)(dian)凈(jing)化(hua)法(fa)來(lai)收捕(bu)廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)粉(fen)(fen)塵，它(ta)的(de)(de)(de)凈(jing)化(hua)工(gong)作(zuo)上要是(shi)依靠電(dian)(dian)(dian)暈極和沉(chen)淀(dian)兩個系(xi)統來(lai)完成的(de)(de)(de)，當含(han)塵氣(qi)(qi)(qi)(qi)體(ti)(ti)進人氣(qi)(qi)(qi)(qi)刺叭時，含(han)塵氣(qi)(qi)(qi)(qi)體(ti)(ti)受(shou)到氣(qi)(qi)(qi)(qi)流(liu)分(fen)布板(ban)(ban)以及(ji)折流(liu)板(ban)(ban)的(de)(de)(de)調整后，使氣(qi)(qi)(qi)(qi)流(liu)能較(jiao)均勻地(di)進人電(dian)(dian)(dian)場(chang)。在橫斷面擴(kuo)大的(de)(de)(de)作(zuo)用下，氣(qi)(qi)(qi)(qi)流(liu)速度迅速降低，其中(zhong)有(you)些(xie)較(jiao)重(zhong)的(de)(de)(de)塵粒(li)便失去速度而沉(chen)降下來(lai)。進人電(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵氣(qi)(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)暈極通人高壓直流(liu)電(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)暈極附近產生電(dian)(dian)(dian)暈現(xian)象，使氣(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)存在大量(liang)的(de)(de)(de)電(dian)(dian)(dian)子和離子，這些(xie)電(dian)(dian)(dian)子和離子與進人電(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)(fen)塵結(jie)合起來(lai)，使塵粒(li)帶(dai)(dai)電(dian)(dian)(dian)，帶(dai)(dai)電(dian)(dian)(dian)塵粒(li)在電(dian)(dian)(dian)場(chang)力的(de)(de)(de)作(zuo)用下趨向本設備(bei)陽極(正極、本設備(bei)采用負高壓制)和陰極(負極) ， 釋放出電(dian)(dian)(dian)子分(fen)別沉(chen)積在相(xiang)應的(de)(de)(de)電(dian)(dian)(dian)極上，通過(guo)設備(bei)陰陽極振(zhen)打(da)(da)系(xi)統的(de)(de)(de)振(zhen)打(da)(da)，使沉(chen)積在陰陽電(dian)(dian)(dian)極上的(de)(de)(de)粉(fen)(fen)塵振(zhen)落，進人集灰(hui)斗 通過(guo)排灰(hui)裝置放出，回收有(you)物料，被(bei))凈(jing)化(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)(qi)。

工作原理(li)

靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的(de)(de)(de)工作原理是利用高(gao)(gao)壓電(dian)(dian)場(chang)使煙(yan)氣發(fa)生電(dian)(dian)離，氣流(liu)中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)在電(dian)(dian)場(chang)作用下與(yu)氣流(liu)分離。負(fu)極(ji)由不(bu)同斷(duan)面形狀的(de)(de)(de)金屬(shu)導(dao)線制(zhi)成(cheng)，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不(bu)同幾何形狀的(de)(de)(de)金屬(shu)板制(zhi)成(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)。靜(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的(de)(de)(de)性能受粉塵(chen)(chen)(chen)(chen)(chen)性質、設備構(gou)造和煙(yan)氣流(liu)速等三個因素的(de)(de)(de)影響。粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)比(bi)(bi)(bi)電(dian)(dian)阻(zu)(zu)是評價導(dao)電(dian)(dian)性的(de)(de)(de)指(zhi)標(biao)，它對除塵(chen)(chen)(chen)(chen)(chen)效率(lv)有直(zhi)接的(de)(de)(de)影響。比(bi)(bi)(bi)電(dian)(dian)阻(zu)(zu)過(guo)低，塵(chen)(chen)(chen)(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使其重返(fan)氣流(liu)。比(bi)(bi)(bi)電(dian)(dian)阻(zu)(zu)過(guo)高(gao)(gao)，到達集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)荷(he)不(bu)易放出(chu)，在塵(chen)(chen)(chen)(chen)(chen)層(ceng)之間形成(cheng)電(dian)(dian)壓梯度會(hui)產生局部擊穿和放電(dian)(dian)現象。這些情況都會(hui)造成(cheng)除塵(chen)(chen)(chen)(chen)(chen)效率(lv)下降。

電除塵(chen)(chen)(chen)器的(de)基(ji)本原理是利(li)用電力捕(bu)集煙氣中的(de)粉(fen)塵(chen)(chen)(chen)，主(zhu)要包括以(yi)下四個(ge)相互有關的(de)物理過程: (1) 氣體的(de)電離。(2) 粉(fen)塵(chen)(chen)(chen)的(de)荷(he)電。(3) 荷(he)電粉(fen)塵(chen)(chen)(chen)向電極移動。(4) 荷(he)電粉(fen)塵(chen)(chen)(chen)的(de)捕(bu)集。
