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)除塵(chen)(chen)(chen)器是以(yi)靜(jing)電(dian)(dian)凈化法(fa)來收捕廢氣(qi)中(zhong)(zhong)的粉塵(chen)(chen)(chen)，它的凈化工作(zuo)上(shang)要是依(yi)靠電(dian)(dian)暈(yun)極(ji)(ji)(ji)和沉淀兩個(ge)系(xi)統來完成(cheng)的，當含(han)塵(chen)(chen)(chen)氣(qi)體(ti)進(jin)人(ren)氣(qi)刺(ci)叭時，含(han)塵(chen)(chen)(chen)氣(qi)體(ti)受(shou)到氣(qi)流分(fen)布板以(yi)及(ji)折(zhe)流板的調整(zheng)后，使氣(qi)流能較均(jun)勻地進(jin)人(ren)電(dian)(dian)場。在(zai)(zai)橫斷面擴大的作(zuo)用(yong)下(xia)，氣(qi)流速(su)度迅速(su)降(jiang)低，其中(zhong)(zhong)有些較重(zhong)的塵(chen)(chen)(chen)粒(li)便(bian)失(shi)去(qu)速(su)度而沉降(jiang)下(xia)來。進(jin)人(ren)電(dian)(dian)場的含(han)塵(chen)(chen)(chen)氣(qi)體(ti)由于電(dian)(dian)暈(yun)極(ji)(ji)(ji)通人(ren)高(gao)壓(ya)直(zhi)流電(dian)(dian)，則在(zai)(zai)電(dian)(dian)暈(yun)極(ji)(ji)(ji)附近(jin)產生電(dian)(dian)暈(yun)現象(xiang)，使氣(qi)體(ti)電(dian)(dian)離(li)，電(dian)(dian)離(li)后的氣(qi)體(ti)中(zhong)(zhong)存在(zai)(zai)大量的電(dian)(dian)子和離(li)子，這些電(dian)(dian)子和離(li)子與進(jin)人(ren)電(dian)(dian)場的粉塵(chen)(chen)(chen)結合(he)起來，使塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)場力的作(zuo)用(yong)下(xia)趨向(xiang)本(ben)設備(bei)陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設備(bei)采用(yong)負(fu)高(gao)壓(ya)制)和陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)子分(fen)別(bie)沉積在(zai)(zai)相(xiang)應的電(dian)(dian)極(ji)(ji)(ji)上(shang)，通過(guo)設備(bei)陰(yin)陽極(ji)(ji)(ji)振(zhen)打系(xi)統的振(zhen)打，使沉積在(zai)(zai)陰(yin)陽電(dian)(dian)極(ji)(ji)(ji)上(shang)的粉塵(chen)(chen)(chen)振(zhen)落，進(jin)人(ren)集灰(hui)斗 通過(guo)排(pai)灰(hui)裝置放(fang)出，回收有物料，被)凈化的氣(qi)體(ti)排(pai)入大氣(qi)。

工作原理

靜(jing)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)工(gong)作(zuo)原理是(shi)(shi)利用高壓電(dian)(dian)場(chang)使煙氣(qi)(qi)(qi)發生電(dian)(dian)離(li)，氣(qi)(qi)(qi)流中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場(chang)作(zuo)用下與氣(qi)(qi)(qi)流分(fen)離(li)。負極(ji)由不(bu)同(tong)斷面形(xing)狀(zhuang)的(de)金屬(shu)導線制成(cheng)，叫(jiao)放(fang)(fang)電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不(bu)同(tong)幾何(he)形(xing)狀(zhuang)的(de)金屬(shu)板制成(cheng)，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)極(ji)。靜(jing)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)質(zhi)、設備構造和(he)煙氣(qi)(qi)(qi)流速等三個因(yin)素的(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)比電(dian)(dian)阻(zu)是(shi)(shi)評價(jia)導電(dian)(dian)性(xing)的(de)指標，它對除(chu)(chu)塵(chen)(chen)(chen)效率有直接的(de)影響。比電(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)粒(li)難以保持(chi)在集塵(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使其重返氣(qi)(qi)(qi)流。比電(dian)(dian)阻(zu)過(guo)高，到達集塵(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)荷不(bu)易放(fang)(fang)出，在塵(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)壓梯度會產生局(ju)部擊(ji)穿和(he)放(fang)(fang)電(dian)(dian)現(xian)象。這些情況都會造成(cheng)除(chu)(chu)塵(chen)(chen)(chen)效率下降(jiang)。

電(dian)除塵器(qi)的(de)(de)(de)基(ji)本原理是(shi)利用電(dian)力捕集(ji)煙氣中的(de)(de)(de)粉塵，主要包括以(yi)下四個相(xiang)互有關(guan)的(de)(de)(de)物理過程: (1) 氣體(ti)的(de)(de)(de)電(dian)離。(2) 粉塵的(de)(de)(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉塵向(xiang)電(dian)極移動。(4) 荷(he)電(dian)粉塵的(de)(de)(de)捕集(ji)。
