XWD型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)(dian)(dian)(dian)除塵(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)(hua)法(fa)來收捕廢氣(qi)中的粉(fen)塵(chen)，它的凈(jing)化(hua)(hua)工作上(shang)要是(shi)依(yi)靠電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)和沉(chen)(chen)淀兩個(ge)系統來完成(cheng)的，當含(han)塵(chen)氣(qi)體(ti)進人(ren)氣(qi)刺叭(ba)時，含(han)塵(chen)氣(qi)體(ti)受到氣(qi)流(liu)分布板(ban)以及折流(liu)板(ban)的調(diao)整后，使(shi)(shi)氣(qi)流(liu)能較(jiao)均勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷面擴(kuo)大(da)的作用(yong)下，氣(qi)流(liu)速度迅速降低，其中有些(xie)(xie)較(jiao)重的塵(chen)粒(li)便失去(qu)速度而沉(chen)(chen)降下來。進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的含(han)塵(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)通(tong)人(ren)高壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)附近(jin)產生電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現(xian)象，使(shi)(shi)氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的氣(qi)體(ti)中存在(zai)(zai)大(da)量的電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)，這些(xie)(xie)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)與(yu)進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的粉(fen)塵(chen)結合起來，使(shi)(shi)塵(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的作用(yong)下趨向本(ben)設備陽極(ji)(正(zheng)極(ji)、本(ben)設備采(cai)用(yong)負高壓(ya)制(zhi))和陰極(ji)(負極(ji)) ， 釋放(fang)(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別沉(chen)(chen)積(ji)在(zai)(zai)相應的電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通(tong)過(guo)設備陰陽極(ji)振打(da)系統的振打(da)，使(shi)(shi)沉(chen)(chen)積(ji)在(zai)(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的粉(fen)塵(chen)振落(luo)，進人(ren)集灰斗 通(tong)過(guo)排灰裝置放(fang)(fang)出(chu)，回收有物料，被)凈(jing)化(hua)(hua)的氣(qi)體(ti)排入大(da)氣(qi)。

工作原理

靜(jing)(jing)電(dian)(dian)除(chu)塵(chen)器(qi)的(de)工作原理是(shi)利用高壓電(dian)(dian)場使煙(yan)(yan)氣發生(sheng)(sheng)電(dian)(dian)離，氣流(liu)(liu)中的(de)粉塵(chen)荷電(dian)(dian)在電(dian)(dian)場作用下(xia)與氣流(liu)(liu)分(fen)離。負極(ji)(ji)由(you)不(bu)同斷面形狀(zhuang)的(de)金屬(shu)導線制成，叫(jiao)放(fang)電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不(bu)同幾何(he)形狀(zhuang)的(de)金屬(shu)板制成，叫(jiao)集(ji)塵(chen)電(dian)(dian)極(ji)(ji)。靜(jing)(jing)電(dian)(dian)除(chu)塵(chen)器(qi)的(de)性能(neng)受粉塵(chen)性質、設備構(gou)造(zao)和煙(yan)(yan)氣流(liu)(liu)速(su)等三個因素的(de)影(ying)響。粉塵(chen)的(de)比電(dian)(dian)阻是(shi)評價導電(dian)(dian)性的(de)指(zhi)標，它(ta)對除(chu)塵(chen)效率(lv)有直接的(de)影(ying)響。比電(dian)(dian)阻過(guo)低，塵(chen)粒難以(yi)保持在集(ji)塵(chen)電(dian)(dian)極(ji)(ji)上(shang)，致使其(qi)重(zhong)返氣流(liu)(liu)。比電(dian)(dian)阻過(guo)高，到達(da)集(ji)塵(chen)電(dian)(dian)極(ji)(ji)的(de)塵(chen)粒電(dian)(dian)荷不(bu)易放(fang)出(chu)，在塵(chen)層之間形成電(dian)(dian)壓梯度會(hui)產生(sheng)(sheng)局部擊(ji)穿和放(fang)電(dian)(dian)現象。這些情(qing)況都會(hui)造(zao)成除(chu)塵(chen)效率(lv)下(xia)降。

電(dian)(dian)除塵(chen)(chen)器(qi)的(de)基本原理(li)是(shi)利用電(dian)(dian)力捕集(ji)煙氣(qi)中的(de)粉(fen)塵(chen)(chen)，主要包括(kuo)以下四個(ge)相互有關(guan)的(de)物理(li)過程: (1) 氣(qi)體的(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)荷(he)(he)電(dian)(dian)。(3) 荷(he)(he)電(dian)(dian)粉(fen)塵(chen)(chen)向(xiang)電(dian)(dian)極移動。(4) 荷(he)(he)電(dian)(dian)粉(fen)塵(chen)(chen)的(de)捕集(ji)。
