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(jing)電(dian)(dian)(dian)(dian)除塵(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)(dian)凈化(hua)(hua)法(fa)來(lai)(lai)收捕廢氣(qi)中(zhong)的(de)(de)(de)(de)(de)粉(fen)塵(chen)，它(ta)的(de)(de)(de)(de)(de)凈化(hua)(hua)工(gong)作(zuo)上要(yao)是(shi)依靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)沉(chen)淀兩個系統(tong)來(lai)(lai)完成的(de)(de)(de)(de)(de)，當含塵(chen)氣(qi)體(ti)(ti)(ti)進(jin)人氣(qi)刺叭時(shi)，含塵(chen)氣(qi)體(ti)(ti)(ti)受到氣(qi)流(liu)分布板以及(ji)折流(liu)板的(de)(de)(de)(de)(de)調整(zheng)后，使氣(qi)流(liu)能(neng)較均勻地進(jin)人電(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴(kuo)大(da)(da)的(de)(de)(de)(de)(de)作(zuo)用(yong)下，氣(qi)流(liu)速度迅速降(jiang)低，其中(zhong)有些較重的(de)(de)(de)(de)(de)塵(chen)粒(li)便失去速度而沉(chen)降(jiang)下來(lai)(lai)。進(jin)人電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)含塵(chen)氣(qi)體(ti)(ti)(ti)由(you)于(yu)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通(tong)人高壓直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈現象，使氣(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)(de)氣(qi)體(ti)(ti)(ti)中(zhong)存在(zai)(zai)大(da)(da)量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子和(he)離(li)子，這些電(dian)(dian)(dian)(dian)子和(he)離(li)子與進(jin)人電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)粉(fen)塵(chen)結合起來(lai)(lai)，使塵(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)作(zuo)用(yong)下趨向本設備(bei)陽極(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)、本設備(bei)采用(yong)負(fu)高壓制)和(he)陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)子分別沉(chen)積在(zai)(zai)相應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通(tong)過設備(bei)陰(yin)陽極(ji)(ji)(ji)振(zhen)(zhen)打系統(tong)的(de)(de)(de)(de)(de)振(zhen)(zhen)打，使沉(chen)積在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)(de)粉(fen)塵(chen)振(zhen)(zhen)落，進(jin)人集灰斗 通(tong)過排(pai)灰裝置放出，回收有物料，被)凈化(hua)(hua)的(de)(de)(de)(de)(de)氣(qi)體(ti)(ti)(ti)排(pai)入大(da)(da)氣(qi)。

工作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)(de)工(gong)作(zuo)原(yuan)理是利用高壓(ya)(ya)電(dian)(dian)(dian)場使煙氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)離，氣(qi)流(liu)(liu)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作(zuo)用下(xia)與氣(qi)流(liu)(liu)分離。負極(ji)由(you)不(bu)(bu)同(tong)斷面形狀的(de)(de)(de)(de)金屬導線制(zhi)成(cheng)(cheng)，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由(you)不(bu)(bu)同(tong)幾何形狀的(de)(de)(de)(de)金屬板制(zhi)成(cheng)(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)(de)性(xing)能受粉塵(chen)(chen)(chen)性(xing)質、設備構造和煙氣(qi)流(liu)(liu)速等三個因素的(de)(de)(de)(de)影(ying)響(xiang)。粉塵(chen)(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)(dian)阻(zu)(zu)是評價導電(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)指標，它對除塵(chen)(chen)(chen)效率有直(zhi)接的(de)(de)(de)(de)影(ying)響(xiang)。比電(dian)(dian)(dian)阻(zu)(zu)過(guo)低，塵(chen)(chen)(chen)粒(li)難(nan)以保持在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)流(liu)(liu)。比電(dian)(dian)(dian)阻(zu)(zu)過(guo)高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)荷不(bu)(bu)易放出，在(zai)塵(chen)(chen)(chen)層(ceng)之間形成(cheng)(cheng)電(dian)(dian)(dian)壓(ya)(ya)梯(ti)度會(hui)產生(sheng)局(ju)部擊(ji)穿和放電(dian)(dian)(dian)現(xian)象。這些情況都會(hui)造成(cheng)(cheng)除塵(chen)(chen)(chen)效率下(xia)降。

電(dian)(dian)除塵(chen)器的(de)(de)(de)基本原(yuan)理是利用電(dian)(dian)力(li)捕集煙氣(qi)中(zhong)的(de)(de)(de)粉(fen)塵(chen)，主要包括以下四個(ge)相(xiang)互(hu)有關的(de)(de)(de)物理過(guo)程: (1) 氣(qi)體的(de)(de)(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)(de)(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉(fen)塵(chen)的(de)(de)(de)捕集。
