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)除塵器是(shi)以(yi)靜電(dian)(dian)凈化(hua)法來(lai)(lai)收捕(bu)廢(fei)氣(qi)(qi)中的(de)(de)(de)(de)(de)粉塵，它的(de)(de)(de)(de)(de)凈化(hua)工作(zuo)上(shang)要是(shi)依靠電(dian)(dian)暈極(ji)(ji)(ji)和沉淀(dian)兩個(ge)系統(tong)來(lai)(lai)完(wan)成的(de)(de)(de)(de)(de)，當含塵氣(qi)(qi)體(ti)(ti)進(jin)人(ren)(ren)(ren)氣(qi)(qi)刺叭時(shi)，含塵氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流(liu)分(fen)布板以(yi)及折(zhe)流(liu)板的(de)(de)(de)(de)(de)調整(zheng)后(hou)(hou)，使(shi)氣(qi)(qi)流(liu)能較均勻地進(jin)人(ren)(ren)(ren)電(dian)(dian)場(chang)。在橫斷(duan)面擴(kuo)大(da)的(de)(de)(de)(de)(de)作(zuo)用(yong)下，氣(qi)(qi)流(liu)速度迅速降低(di)，其中有些(xie)較重的(de)(de)(de)(de)(de)塵粒便失去(qu)速度而沉降下來(lai)(lai)。進(jin)人(ren)(ren)(ren)電(dian)(dian)場(chang)的(de)(de)(de)(de)(de)含塵氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)暈極(ji)(ji)(ji)通(tong)人(ren)(ren)(ren)高壓直流(liu)電(dian)(dian)，則在電(dian)(dian)暈極(ji)(ji)(ji)附近產生電(dian)(dian)暈現(xian)象，使(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)離，電(dian)(dian)離后(hou)(hou)的(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)中存在大(da)量的(de)(de)(de)(de)(de)電(dian)(dian)子(zi)(zi)和離子(zi)(zi)，這些(xie)電(dian)(dian)子(zi)(zi)和離子(zi)(zi)與進(jin)人(ren)(ren)(ren)電(dian)(dian)場(chang)的(de)(de)(de)(de)(de)粉塵結(jie)合起來(lai)(lai)，使(shi)塵粒帶(dai)(dai)電(dian)(dian)，帶(dai)(dai)電(dian)(dian)塵粒在電(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)作(zuo)用(yong)下趨向本設備(bei)陽(yang)(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備(bei)采用(yong)負高壓制)和陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)子(zi)(zi)分(fen)別沉積(ji)在相應的(de)(de)(de)(de)(de)電(dian)(dian)極(ji)(ji)(ji)上(shang)，通(tong)過設備(bei)陰陽(yang)(yang)極(ji)(ji)(ji)振(zhen)(zhen)打系統(tong)的(de)(de)(de)(de)(de)振(zhen)(zhen)打，使(shi)沉積(ji)在陰陽(yang)(yang)電(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)(de)(de)粉塵振(zhen)(zhen)落，進(jin)人(ren)(ren)(ren)集灰斗 通(tong)過排(pai)(pai)灰裝置放(fang)出，回收有物(wu)料，被)凈化(hua)的(de)(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)排(pai)(pai)入(ru)大(da)氣(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)工(gong)作原理是利用(yong)高(gao)壓電(dian)(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)流中(zhong)的(de)(de)粉塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用(yong)下與氣(qi)流分離。負極(ji)由不同斷面形狀(zhuang)的(de)(de)金(jin)屬導(dao)(dao)線(xian)制(zhi)(zhi)成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由不同幾何形狀(zhuang)的(de)(de)金(jin)屬板制(zhi)(zhi)成(cheng)，叫(jiao)集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)性能受粉塵(chen)(chen)(chen)性質、設備構(gou)造和(he)煙氣(qi)流速(su)等三個因素的(de)(de)影(ying)響。粉塵(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)阻是評價導(dao)(dao)電(dian)(dian)(dian)(dian)性的(de)(de)指標，它(ta)對除塵(chen)(chen)(chen)效率有(you)直接的(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)阻過(guo)(guo)低(di)，塵(chen)(chen)(chen)粒難以保持(chi)在集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其(qi)重(zhong)返氣(qi)流。比電(dian)(dian)(dian)(dian)阻過(guo)(guo)高(gao)，到(dao)達集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不易放(fang)出，在塵(chen)(chen)(chen)層之間(jian)形成(cheng)電(dian)(dian)(dian)(dian)壓梯度會產生局(ju)部(bu)擊穿和(he)放(fang)電(dian)(dian)(dian)(dian)現(xian)象。這些情(qing)況都會造成(cheng)除塵(chen)(chen)(chen)效率下降(jiang)。

電除塵(chen)器的(de)基本原理是(shi)利用電力捕(bu)集(ji)煙氣(qi)中的(de)粉(fen)塵(chen)，主要包括以下(xia)四個相互有(you)關的(de)物(wu)理過(guo)程: (1) 氣(qi)體(ti)的(de)電離。(2) 粉(fen)塵(chen)的(de)荷(he)電。(3) 荷(he)電粉(fen)塵(chen)向(xiang)電極移動。(4) 荷(he)電粉(fen)塵(chen)的(de)捕(bu)集(ji)。
