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)(dian)除塵(chen)(chen)器(qi)是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法來(lai)收捕(bu)廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)(de)凈(jing)(jing)化(hua)工作(zuo)上(shang)要(yao)是依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)和沉(chen)淀兩個系(xi)統來(lai)完成的(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進(jin)(jin)人氣(qi)(qi)(qi)刺叭(ba)時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流(liu)(liu)分布板以(yi)及折流(liu)(liu)板的(de)(de)(de)(de)調整后，使氣(qi)(qi)(qi)流(liu)(liu)能(neng)較均(jun)勻地進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場。在橫斷面擴大的(de)(de)(de)(de)作(zuo)用下，氣(qi)(qi)(qi)流(liu)(liu)速(su)(su)度(du)迅速(su)(su)降(jiang)(jiang)低，其中有些較重的(de)(de)(de)(de)塵(chen)(chen)粒(li)便失去速(su)(su)度(du)而沉(chen)降(jiang)(jiang)下來(lai)。進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈極(ji)通(tong)人高(gao)壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)暈極(ji)附(fu)近產生(sheng)電(dian)(dian)(dian)(dian)(dian)暈現(xian)象，使氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中存(cun)在大量(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和離子，這(zhe)些電(dian)(dian)(dian)(dian)(dian)子和離子與進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)(chen)結合(he)起來(lai)，使塵(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用下趨向本(ben)設(she)備(bei)陽極(ji)(正(zheng)極(ji)、本(ben)設(she)備(bei)采用負(fu)高(gao)壓制(zhi))和陰(yin)(yin)極(ji)(負(fu)極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積在相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通(tong)過(guo)設(she)備(bei)陰(yin)(yin)陽極(ji)振打系(xi)統的(de)(de)(de)(de)振打，使沉(chen)積在陰(yin)(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)振落，進(jin)(jin)人集灰斗 通(tong)過(guo)排灰裝置放出，回(hui)收有物料，被)凈(jing)(jing)化(hua)的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)(de)(de)工作原理(li)是利用高壓(ya)電(dian)(dian)(dian)場使(shi)煙氣(qi)發生電(dian)(dian)(dian)離(li)，氣(qi)流(liu)中的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)場作用下與氣(qi)流(liu)分(fen)離(li)。負極(ji)(ji)(ji)由(you)不同斷面形狀(zhuang)(zhuang)的(de)(de)(de)(de)(de)金屬(shu)導(dao)線(xian)制(zhi)成(cheng)，叫(jiao)放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由(you)不同幾何(he)形狀(zhuang)(zhuang)的(de)(de)(de)(de)(de)金屬(shu)板制(zhi)成(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)質、設備(bei)構造和煙氣(qi)流(liu)速等三(san)個因素的(de)(de)(de)(de)(de)影(ying)(ying)響。粉(fen)塵(chen)(chen)(chen)的(de)(de)(de)(de)(de)比(bi)(bi)電(dian)(dian)(dian)阻(zu)(zu)是評(ping)價導(dao)電(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)(chen)效(xiao)(xiao)率(lv)有直(zhi)接的(de)(de)(de)(de)(de)影(ying)(ying)響。比(bi)(bi)電(dian)(dian)(dian)阻(zu)(zu)過(guo)低(di)，塵(chen)(chen)(chen)粒難以保持在(zai)(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，致(zhi)使(shi)其重(zhong)返(fan)氣(qi)流(liu)。比(bi)(bi)電(dian)(dian)(dian)阻(zu)(zu)過(guo)高，到達(da)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易(yi)放(fang)(fang)出(chu)，在(zai)(zai)塵(chen)(chen)(chen)層之間(jian)形成(cheng)電(dian)(dian)(dian)壓(ya)梯度會產(chan)生局部擊穿和放(fang)(fang)電(dian)(dian)(dian)現(xian)象。這些情況都會造成(cheng)除(chu)(chu)塵(chen)(chen)(chen)效(xiao)(xiao)率(lv)下降。

電(dian)除塵器的(de)(de)基本原理是利用電(dian)力捕集煙(yan)氣中的(de)(de)粉塵，主要包(bao)括以(yi)下四個相互(hu)有關(guan)的(de)(de)物理過程(cheng): (1) 氣體的(de)(de)電(dian)離。(2) 粉塵的(de)(de)荷電(dian)。(3) 荷電(dian)粉塵向電(dian)極(ji)移動(dong)。(4) 荷電(dian)粉塵的(de)(de)捕集。
