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(shi)靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法(fa)來(lai)(lai)(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)粉塵(chen)(chen)，它(ta)的(de)(de)凈(jing)化(hua)工作(zuo)(zuo)上(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)沉(chen)(chen)淀兩個系(xi)統來(lai)(lai)(lai)完成的(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)(qi)刺叭(ba)時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)(liu)分布板(ban)以及折流(liu)(liu)板(ban)的(de)(de)調整后(hou)，使氣(qi)(qi)(qi)流(liu)(liu)能(neng)較均勻地(di)進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面擴大(da)的(de)(de)作(zuo)(zuo)用下，氣(qi)(qi)(qi)流(liu)(liu)速度(du)迅速降(jiang)低，其中有些(xie)較重的(de)(de)塵(chen)(chen)粒(li)便(bian)失去速度(du)而沉(chen)(chen)降(jiang)下來(lai)(lai)(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通(tong)人(ren)高(gao)壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附(fu)近產(chan)生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)氣(qi)(qi)(qi)體(ti)中存在(zai)大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離子，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離子與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)結合起來(lai)(lai)(lai)，使塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)(zuo)用下趨向(xiang)本(ben)設(she)(she)備(bei)陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設(she)(she)備(bei)采用負高(gao)壓制(zhi))和(he)陰(yin)(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)子分別沉(chen)(chen)積在(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通(tong)過設(she)(she)備(bei)陰(yin)(yin)陽極(ji)(ji)(ji)振(zhen)(zhen)打系(xi)統的(de)(de)振(zhen)(zhen)打，使沉(chen)(chen)積在(zai)陰(yin)(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)粉塵(chen)(chen)振(zhen)(zhen)落，進(jin)人(ren)集(ji)灰(hui)斗(dou) 通(tong)過排灰(hui)裝置放(fang)出，回收有物料(liao)，被(bei))凈(jing)化(hua)的(de)(de)氣(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)。

工作原理(li)

靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)工作原理(li)是利用高(gao)(gao)壓(ya)電(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)(qi)(qi)發生電(dian)(dian)(dian)離(li)，氣(qi)(qi)(qi)流(liu)中(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)作用下與氣(qi)(qi)(qi)流(liu)分離(li)。負極由(you)不(bu)同(tong)斷面形狀的(de)(de)(de)金屬導(dao)線制成，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由(you)不(bu)同(tong)幾何形狀的(de)(de)(de)金屬板制成，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)性能受(shou)粉塵(chen)(chen)(chen)性質、設備構造和(he)煙(yan)氣(qi)(qi)(qi)流(liu)速等三個因素的(de)(de)(de)影響。粉塵(chen)(chen)(chen)的(de)(de)(de)比(bi)(bi)電(dian)(dian)(dian)阻(zu)是評價(jia)導(dao)電(dian)(dian)(dian)性的(de)(de)(de)指(zhi)標(biao)，它對除塵(chen)(chen)(chen)效(xiao)率(lv)有(you)直接的(de)(de)(de)影響。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)粒難以保持(chi)在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極上，致(zhi)使其重返氣(qi)(qi)(qi)流(liu)。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)高(gao)(gao)，到達(da)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易(yi)放出(chu)，在(zai)塵(chen)(chen)(chen)層(ceng)之間形成電(dian)(dian)(dian)壓(ya)梯度會(hui)產生局部擊穿和(he)放電(dian)(dian)(dian)現象。這些(xie)情況(kuang)都會(hui)造成除塵(chen)(chen)(chen)效(xiao)率(lv)下降。

電(dian)(dian)(dian)除(chu)塵器的(de)基本原理是利用電(dian)(dian)(dian)力捕集煙(yan)氣中的(de)粉(fen)塵，主要包括以下四(si)個相互有(you)關的(de)物理過程(cheng): (1) 氣體的(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵的(de)荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉(fen)塵向電(dian)(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)(dian)粉(fen)塵的(de)捕集。
