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(wo)式靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器是(shi)以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈化法來(lai)收(shou)捕廢氣(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)凈化工作上要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)和沉(chen)淀(dian)兩個系統(tong)來(lai)完成(cheng)的(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體進(jin)人氣(qi)(qi)(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)流(liu)分(fen)布板以(yi)及折流(liu)板的(de)(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)(qi)(qi)流(liu)能較均(jun)勻(yun)地(di)進(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在橫斷面擴(kuo)大(da)的(de)(de)(de)(de)作用下，氣(qi)(qi)(qi)(qi)流(liu)速度迅速降低(di)，其中有些(xie)較重(zhong)的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)便(bian)失去速度而沉(chen)降下來(lai)。進(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體由(you)于電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)通(tong)人高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現象(xiang)，使(shi)(shi)氣(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體中存在大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和離子，這些(xie)電(dian)(dian)(dian)(dian)(dian)子和離子與進(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)結合起來(lai)，使(shi)(shi)塵(chen)(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)作用下趨向本(ben)設(she)(she)備陽(yang)極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本(ben)設(she)(she)備采(cai)用負高壓(ya)制(zhi))和陰(yin)極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放出(chu)(chu)電(dian)(dian)(dian)(dian)(dian)子分(fen)別沉(chen)積在相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，通(tong)過(guo)設(she)(she)備陰(yin)陽(yang)極(ji)(ji)(ji)(ji)振(zhen)打系統(tong)的(de)(de)(de)(de)振(zhen)打，使(shi)(shi)沉(chen)積在陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)振(zhen)落，進(jin)人集灰(hui)斗 通(tong)過(guo)排灰(hui)裝置放出(chu)(chu)，回收(shou)有物料(liao)，被)凈化的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體排入大(da)氣(qi)(qi)(qi)(qi)。

工(gong)作原理

靜(jing)電除(chu)塵(chen)(chen)(chen)器的(de)工作(zuo)原理(li)是利(li)用高壓(ya)電場使煙(yan)氣(qi)發(fa)生電離，氣(qi)流(liu)中(zhong)的(de)粉塵(chen)(chen)(chen)荷(he)電在電場作(zuo)用下與氣(qi)流(liu)分離。負極(ji)由不(bu)同斷面形狀的(de)金屬導線制成，叫放電電極(ji)。正極(ji)由不(bu)同幾何(he)形狀的(de)金屬板制成，叫集(ji)塵(chen)(chen)(chen)電極(ji)。靜(jing)電除(chu)塵(chen)(chen)(chen)器的(de)性(xing)(xing)能(neng)受粉塵(chen)(chen)(chen)性(xing)(xing)質(zhi)、設(she)備(bei)構造和煙(yan)氣(qi)流(liu)速(su)等三(san)個因素的(de)影(ying)響(xiang)。粉塵(chen)(chen)(chen)的(de)比(bi)電阻(zu)是評價導電性(xing)(xing)的(de)指標，它對(dui)除(chu)塵(chen)(chen)(chen)效(xiao)率有直接的(de)影(ying)響(xiang)。比(bi)電阻(zu)過低，塵(chen)(chen)(chen)粒(li)難以保(bao)持在集(ji)塵(chen)(chen)(chen)電極(ji)上，致使其(qi)重返氣(qi)流(liu)。比(bi)電阻(zu)過高，到達集(ji)塵(chen)(chen)(chen)電極(ji)的(de)塵(chen)(chen)(chen)粒(li)電荷(he)不(bu)易放出(chu)，在塵(chen)(chen)(chen)層之間形成電壓(ya)梯度會(hui)產生局(ju)部(bu)擊穿和放電現象。這(zhe)些情況都(dou)會(hui)造成除(chu)塵(chen)(chen)(chen)效(xiao)率下降。

電除塵(chen)器的(de)基本(ben)原理是利(li)用(yong)電力(li)捕(bu)(bu)集(ji)煙氣中的(de)粉(fen)塵(chen)，主要包括以下四個相互有關的(de)物理過程: (1) 氣體的(de)電離。(2) 粉(fen)塵(chen)的(de)荷(he)電。(3) 荷(he)電粉(fen)塵(chen)向電極移動。(4) 荷(he)電粉(fen)塵(chen)的(de)捕(bu)(bu)集(ji)。
