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。

臥式靜電(dian)(dian)除塵(chen)(chen)器是以靜電(dian)(dian)凈化(hua)法來(lai)(lai)收捕廢氣(qi)中的(de)(de)(de)粉塵(chen)(chen)，它(ta)的(de)(de)(de)凈化(hua)工作(zuo)上要是依靠電(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)和(he)沉(chen)淀兩個(ge)系統來(lai)(lai)完(wan)成(cheng)的(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)體(ti)進(jin)人(ren)氣(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)體(ti)受到氣(qi)流(liu)分布板(ban)以及折流(liu)板(ban)的(de)(de)(de)調(diao)整后，使(shi)氣(qi)流(liu)能較均勻地進(jin)人(ren)電(dian)(dian)場(chang)。在(zai)橫斷面(mian)擴大(da)的(de)(de)(de)作(zuo)用(yong)(yong)下，氣(qi)流(liu)速度迅速降低，其中有些較重的(de)(de)(de)塵(chen)(chen)粒(li)便失去速度而沉(chen)降下來(lai)(lai)。進(jin)人(ren)電(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)(chen)氣(qi)體(ti)由于(yu)電(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)通人(ren)高壓直(zhi)流(liu)電(dian)(dian)，則在(zai)電(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)附近產(chan)生(sheng)電(dian)(dian)暈(yun)(yun)現象，使(shi)氣(qi)體(ti)電(dian)(dian)離(li)(li)，電(dian)(dian)離(li)(li)后的(de)(de)(de)氣(qi)體(ti)中存在(zai)大(da)量的(de)(de)(de)電(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)，這(zhe)些電(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)與(yu)進(jin)人(ren)電(dian)(dian)場(chang)的(de)(de)(de)粉塵(chen)(chen)結合起來(lai)(lai)，使(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)場(chang)力的(de)(de)(de)作(zuo)用(yong)(yong)下趨向本設備陽(yang)(yang)極(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)、本設備采用(yong)(yong)負高壓制(zhi))和(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)子(zi)(zi)分別沉(chen)積在(zai)相應的(de)(de)(de)電(dian)(dian)極(ji)(ji)(ji)上，通過(guo)設備陰陽(yang)(yang)極(ji)(ji)(ji)振(zhen)(zhen)打系統的(de)(de)(de)振(zhen)(zhen)打，使(shi)沉(chen)積在(zai)陰陽(yang)(yang)電(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)粉塵(chen)(chen)振(zhen)(zhen)落，進(jin)人(ren)集灰斗 通過(guo)排(pai)灰裝置放出(chu)，回收有物料，被)凈化(hua)的(de)(de)(de)氣(qi)體(ti)排(pai)入大(da)氣(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)工作(zuo)(zuo)原(yuan)理是利用高壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中的(de)粉塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)(zuo)用下(xia)與氣(qi)流(liu)分離(li)。負(fu)極(ji)由不(bu)(bu)同斷面形狀的(de)金屬導(dao)線制成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)(bu)同幾何形狀的(de)金屬板(ban)制成(cheng)，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)性(xing)能(neng)受粉塵(chen)(chen)(chen)性(xing)質、設備構造和煙(yan)氣(qi)流(liu)速等三個(ge)因素的(de)影(ying)響。粉塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)是評價導(dao)電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)指標，它對除塵(chen)(chen)(chen)效率有直(zhi)接的(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)粒難以(yi)保(bao)持在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重(zhong)返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)高，到達(da)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)(bu)易放出，在(zai)塵(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)梯度會產生(sheng)局部擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這(zhe)些情(qing)況(kuang)都會造成(cheng)除塵(chen)(chen)(chen)效率下(xia)降(jiang)。

電(dian)除(chu)塵(chen)器的基本原理是利用電(dian)力捕集煙氣中的粉塵(chen)，主要(yao)包括以下四(si)個相互有關(guan)的物理過(guo)程: (1) 氣體的電(dian)離(li)。(2) 粉塵(chen)的荷電(dian)。(3) 荷電(dian)粉塵(chen)向電(dian)極(ji)移動。(4) 荷電(dian)粉塵(chen)的捕集。
