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)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是(shi)以(yi)(yi)靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)法(fa)來(lai)收(shou)捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)(de)凈化(hua)工作(zuo)上要是(shi)依(yi)靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和(he)沉(chen)(chen)(chen)淀兩(liang)個系(xi)統(tong)來(lai)完成(cheng)的(de)(de)(de)(de)，當(dang)含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進(jin)人氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受(shou)到氣(qi)(qi)(qi)流(liu)(liu)(liu)分布(bu)板以(yi)(yi)及折流(liu)(liu)(liu)板的(de)(de)(de)(de)調(diao)整后，使(shi)氣(qi)(qi)(qi)流(liu)(liu)(liu)能(neng)較均(jun)勻地(di)進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)橫(heng)斷面擴大(da)的(de)(de)(de)(de)作(zuo)用(yong)(yong)下(xia)，氣(qi)(qi)(qi)流(liu)(liu)(liu)速(su)度迅速(su)降低，其中(zhong)有些(xie)較重的(de)(de)(de)(de)塵(chen)(chen)(chen)粒便失去速(su)度而(er)沉(chen)(chen)(chen)降下(xia)來(lai)。進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通人高壓直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現(xian)象，使(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中(zhong)存在(zai)(zai)大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子與進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)結合(he)起來(lai)，使(shi)塵(chen)(chen)(chen)粒帶(dai)(dai)電(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)(dai)電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用(yong)(yong)下(xia)趨向本設備陽(yang)極(ji)(ji)(正極(ji)(ji)、本設備采用(yong)(yong)負高壓制(zhi))和(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)子分別沉(chen)(chen)(chen)積(ji)在(zai)(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通過設備陰陽(yang)極(ji)(ji)振打系(xi)統(tong)的(de)(de)(de)(de)振打，使(shi)沉(chen)(chen)(chen)積(ji)在(zai)(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)振落，進(jin)人集灰斗 通過排灰裝置放(fang)出(chu)，回(hui)收(shou)有物料，被)凈化(hua)的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排入大(da)氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)(qi)的(de)工作(zuo)原理是利用高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣發生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，氣流中的(de)粉(fen)(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作(zuo)用下(xia)(xia)與(yu)氣流分離。負極(ji)由(you)不(bu)(bu)同斷面形(xing)(xing)狀的(de)金屬導線(xian)制成，叫放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不(bu)(bu)同幾(ji)何形(xing)(xing)狀的(de)金屬板制成，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)(qi)的(de)性(xing)能受(shou)粉(fen)(fen)塵(chen)(chen)(chen)性(xing)質、設備構造和煙(yan)氣流速(su)等三個因素的(de)影響。粉(fen)(fen)塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)指(zhi)標(biao)，它對除塵(chen)(chen)(chen)效率有直接的(de)影響。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒(li)(li)難以保持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣流。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)粒(li)(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷不(bu)(bu)易放出，在塵(chen)(chen)(chen)層之間形(xing)(xing)成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會產(chan)生局部擊(ji)穿和放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況(kuang)都會造成除塵(chen)(chen)(chen)效率下(xia)(xia)降。

電(dian)(dian)(dian)除塵器的(de)(de)(de)基本(ben)原理是利用電(dian)(dian)(dian)力捕集煙(yan)氣(qi)中的(de)(de)(de)粉(fen)塵，主要包括以下(xia)四個相互有關的(de)(de)(de)物理過(guo)程(cheng): (1) 氣(qi)體(ti)的(de)(de)(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵的(de)(de)(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉(fen)塵向電(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)粉(fen)塵的(de)(de)(de)捕集。
