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)除塵(chen)(chen)(chen)(chen)器是以(yi)靜電(dian)(dian)凈化法(fa)來(lai)(lai)收(shou)捕廢氣(qi)(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)凈化工作上要是依靠電(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)沉淀兩個(ge)系(xi)統來(lai)(lai)完成的(de)(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體進人(ren)氣(qi)(qi)(qi)(qi)(qi)刺(ci)叭時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)(qi)流(liu)分布板以(yi)及折流(liu)板的(de)(de)(de)(de)調整后，使氣(qi)(qi)(qi)(qi)(qi)流(liu)能較均勻(yun)地進人(ren)電(dian)(dian)場(chang)。在(zai)(zai)橫(heng)斷面擴大的(de)(de)(de)(de)作用(yong)下，氣(qi)(qi)(qi)(qi)(qi)流(liu)速度(du)迅速降低，其中有些較重的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒便失去速度(du)而沉降下來(lai)(lai)。進人(ren)電(dian)(dian)場(chang)的(de)(de)(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體由于電(dian)(dian)暈(yun)極(ji)(ji)(ji)通人(ren)高壓(ya)直(zhi)流(liu)電(dian)(dian)，則在(zai)(zai)電(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)(qi)(qi)體電(dian)(dian)離(li)，電(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體中存在(zai)(zai)大量的(de)(de)(de)(de)電(dian)(dian)子(zi)和(he)離(li)子(zi)，這些電(dian)(dian)子(zi)和(he)離(li)子(zi)與進人(ren)電(dian)(dian)場(chang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)結合(he)起來(lai)(lai)，使塵(chen)(chen)(chen)(chen)粒帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)(chen)(chen)粒在(zai)(zai)電(dian)(dian)場(chang)力的(de)(de)(de)(de)作用(yong)下趨向(xiang)本設備陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備采用(yong)負高壓(ya)制(zhi))和(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)子(zi)分別沉積在(zai)(zai)相應的(de)(de)(de)(de)電(dian)(dian)極(ji)(ji)(ji)上，通過設備陰陽(yang)極(ji)(ji)(ji)振打系(xi)統的(de)(de)(de)(de)振打，使沉積在(zai)(zai)陰陽(yang)電(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)振落，進人(ren)集灰斗 通過排灰裝(zhuang)置放(fang)出，回收(shou)有物料，被)凈化的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體排入大氣(qi)(qi)(qi)(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)工作(zuo)原(yuan)理是(shi)(shi)利用(yong)高(gao)壓電(dian)(dian)(dian)(dian)場使煙氣發生(sheng)電(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)場作(zuo)用(yong)下(xia)與氣流(liu)分(fen)離。負極(ji)由不同(tong)斷(duan)面形(xing)狀的(de)金(jin)屬導(dao)線(xian)制成，叫放(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同(tong)幾何形(xing)狀的(de)金(jin)屬板制成，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)性能(neng)受粉塵(chen)(chen)(chen)(chen)性質、設備構造和(he)煙氣流(liu)速(su)等三(san)個因素的(de)影響。粉塵(chen)(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)是(shi)(shi)評價導(dao)電(dian)(dian)(dian)(dian)性的(de)指標，它對除(chu)塵(chen)(chen)(chen)(chen)效率(lv)有(you)直接(jie)的(de)影響。比(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)(chen)(chen)粒難以(yi)保持在(zai)(zai)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其重返(fan)氣流(liu)。比(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)過高(gao)，到達(da)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易(yi)放(fang)(fang)出，在(zai)(zai)塵(chen)(chen)(chen)(chen)層(ceng)之間形(xing)成電(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局(ju)部擊穿和(he)放(fang)(fang)電(dian)(dian)(dian)(dian)現象。這些情況都會造成除(chu)塵(chen)(chen)(chen)(chen)效率(lv)下(xia)降。

電(dian)除塵(chen)器的(de)基本(ben)原(yuan)理是利用電(dian)力捕集(ji)煙氣中的(de)粉(fen)塵(chen)，主要包括(kuo)以下四(si)個相(xiang)互有關的(de)物理過(guo)程: (1) 氣體(ti)(ti)的(de)電(dian)離。(2) 粉(fen)塵(chen)的(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)向電(dian)極移動。(4) 荷電(dian)粉(fen)塵(chen)的(de)捕集(ji)。
