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)式靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)凈(jing)化(hua)(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，它(ta)的(de)(de)(de)凈(jing)化(hua)(hua)工(gong)作上(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉(chen)淀兩個系(xi)統來(lai)完(wan)成的(de)(de)(de)，當含(han)(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)(qi)刺(ci)叭(ba)時，含(han)(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)受到(dao)氣(qi)(qi)(qi)流(liu)分布板(ban)以及折流(liu)板(ban)的(de)(de)(de)調整后，使氣(qi)(qi)(qi)流(liu)能較均(jun)勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)橫斷面擴(kuo)大(da)的(de)(de)(de)作用下，氣(qi)(qi)(qi)流(liu)速(su)度(du)迅速(su)降低，其中有些較重的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)(li)便失(shi)去速(su)度(du)而沉(chen)降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)含(han)(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)通(tong)人(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)氣(qi)(qi)(qi)體(ti)中存(cun)在(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子和離(li)子，這些電(dian)(dian)(dian)(dian)子和離(li)子與進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)結合起來(lai)，使塵(chen)(chen)(chen)(chen)粒(li)(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)(li)在(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)力(li)的(de)(de)(de)作用下趨(qu)向本(ben)設備陽極(ji)(正極(ji)、本(ben)設備采用負高壓制)和陰(yin)極(ji)(負極(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)子分別(bie)沉(chen)積在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)上(shang)，通(tong)過設備陰(yin)陽極(ji)振打系(xi)統的(de)(de)(de)振打，使沉(chen)積在(zai)陰(yin)陽電(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)振落，進(jin)人(ren)集灰斗 通(tong)過排(pai)灰裝置放出(chu)，回收有物料，被)凈(jing)化(hua)(hua)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)排(pai)入大(da)氣(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)除(chu)(chu)塵(chen)(chen)器的(de)(de)(de)工(gong)作原理是利用(yong)高壓(ya)電(dian)場使煙氣(qi)發生電(dian)離，氣(qi)流(liu)中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)荷(he)電(dian)在(zai)電(dian)場作用(yong)下與氣(qi)流(liu)分離。負極(ji)由不(bu)同(tong)斷面形狀(zhuang)的(de)(de)(de)金屬(shu)導(dao)線制成(cheng)(cheng)，叫放電(dian)電(dian)極(ji)。正極(ji)由不(bu)同(tong)幾何形狀(zhuang)的(de)(de)(de)金屬(shu)板(ban)制成(cheng)(cheng)，叫集(ji)塵(chen)(chen)電(dian)極(ji)。靜電(dian)除(chu)(chu)塵(chen)(chen)器的(de)(de)(de)性能(neng)受粉(fen)(fen)塵(chen)(chen)性質、設備構(gou)造和煙氣(qi)流(liu)速等(deng)三(san)個因(yin)素的(de)(de)(de)影響。粉(fen)(fen)塵(chen)(chen)的(de)(de)(de)比(bi)電(dian)阻(zu)(zu)是評價導(dao)電(dian)性的(de)(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)效率有直(zhi)接的(de)(de)(de)影響。比(bi)電(dian)阻(zu)(zu)過(guo)低，塵(chen)(chen)粒難(nan)以(yi)保持在(zai)集(ji)塵(chen)(chen)電(dian)極(ji)上(shang)，致使其重(zhong)返氣(qi)流(liu)。比(bi)電(dian)阻(zu)(zu)過(guo)高，到達(da)集(ji)塵(chen)(chen)電(dian)極(ji)的(de)(de)(de)塵(chen)(chen)粒電(dian)荷(he)不(bu)易放出，在(zai)塵(chen)(chen)層(ceng)之間形成(cheng)(cheng)電(dian)壓(ya)梯度會產(chan)生局部擊(ji)穿和放電(dian)現(xian)象。這些情況都(dou)會造成(cheng)(cheng)除(chu)(chu)塵(chen)(chen)效率下降。

電(dian)(dian)除塵(chen)器(qi)的基本原理是利用電(dian)(dian)力(li)捕(bu)集(ji)煙氣(qi)中的粉塵(chen)，主要包括以下四個相互(hu)有關的物理過程: (1) 氣(qi)體的電(dian)(dian)離。(2) 粉塵(chen)的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉塵(chen)的捕(bu)集(ji)。
