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(wo)式靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)(hua)法來收捕(bu)廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化(hua)(hua)工作上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)和(he)沉淀兩個系統來完成的(de)(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)進人氣(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)受(shou)到氣(qi)(qi)(qi)流(liu)分(fen)布板以及折流(liu)板的(de)(de)(de)(de)調(diao)整后，使(shi)氣(qi)(qi)(qi)流(liu)能較均(jun)勻地進人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面(mian)擴(kuo)大(da)的(de)(de)(de)(de)作用(yong)(yong)下，氣(qi)(qi)(qi)流(liu)速(su)(su)度(du)迅(xun)速(su)(su)降低，其中有些(xie)較重的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒便失(shi)去(qu)速(su)(su)度(du)而沉降下來。進人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)通人高壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)附近(jin)產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈現象(xiang)，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)中存在(zai)大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)與進人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)結(jie)合起來，使(shi)塵(chen)(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作用(yong)(yong)下趨向本(ben)設備陽極(ji)(正極(ji)、本(ben)設備采用(yong)(yong)負高壓(ya)制)和(he)陰極(ji)(負極(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別沉積在(zai)相應(ying)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通過(guo)設備陰陽極(ji)振打系統的(de)(de)(de)(de)振打，使(shi)沉積在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)振落(luo)，進人集灰斗 通過(guo)排灰裝置放出(chu)，回收有物料，被)凈(jing)化(hua)(hua)的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)排入(ru)大(da)氣(qi)(qi)(qi)。

工作原理(li)

靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)工作原理是利用高壓(ya)電(dian)(dian)場(chang)使煙氣(qi)(qi)發生電(dian)(dian)離，氣(qi)(qi)流(liu)中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)在電(dian)(dian)場(chang)作用下與氣(qi)(qi)流(liu)分離。負極(ji)由不(bu)(bu)同斷(duan)面形狀的(de)金(jin)屬(shu)導線制(zhi)成(cheng)(cheng)(cheng)，叫放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不(bu)(bu)同幾何形狀的(de)金(jin)屬(shu)板制(zhi)成(cheng)(cheng)(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)性(xing)(xing)能(neng)受粉(fen)塵(chen)(chen)(chen)(chen)性(xing)(xing)質(zhi)、設備構造(zao)和煙氣(qi)(qi)流(liu)速等三個(ge)因素的(de)影響(xiang)(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)的(de)比電(dian)(dian)阻(zu)是評價導電(dian)(dian)性(xing)(xing)的(de)指(zhi)標，它對除(chu)塵(chen)(chen)(chen)(chen)效率(lv)有直接的(de)影響(xiang)(xiang)。比電(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)(chen)粒(li)難(nan)以保持在集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使其(qi)重返氣(qi)(qi)流(liu)。比電(dian)(dian)阻(zu)過(guo)高，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)荷(he)不(bu)(bu)易(yi)放出，在塵(chen)(chen)(chen)(chen)層之間形成(cheng)(cheng)(cheng)電(dian)(dian)壓(ya)梯度(du)會產生局部擊(ji)穿(chuan)和放電(dian)(dian)現(xian)象。這些(xie)情況都會造(zao)成(cheng)(cheng)(cheng)除(chu)塵(chen)(chen)(chen)(chen)效率(lv)下降。

電(dian)除塵器的(de)(de)基本原理是利用電(dian)力捕(bu)集(ji)煙氣(qi)中的(de)(de)粉塵，主要包括以下四個相(xiang)互(hu)有關的(de)(de)物理過程: (1) 氣(qi)體的(de)(de)電(dian)離(li)。(2) 粉塵的(de)(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉塵向電(dian)極移動。(4) 荷(he)電(dian)粉塵的(de)(de)捕(bu)集(ji)。
