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)除塵器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法來收(shou)捕廢氣(qi)中的(de)(de)(de)(de)(de)粉(fen)塵，它的(de)(de)(de)(de)(de)凈(jing)(jing)化(hua)工作(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和沉(chen)淀兩個系統來完成(cheng)的(de)(de)(de)(de)(de)，當含(han)(han)塵氣(qi)體進(jin)人氣(qi)刺(ci)叭時，含(han)(han)塵氣(qi)體受到氣(qi)流(liu)(liu)分布(bu)板以(yi)及折流(liu)(liu)板的(de)(de)(de)(de)(de)調整后(hou)，使(shi)氣(qi)流(liu)(liu)能(neng)較均勻地進(jin)人電(dian)(dian)(dian)(dian)(dian)場。在橫斷面擴大的(de)(de)(de)(de)(de)作(zuo)用下，氣(qi)流(liu)(liu)速度迅速降低，其中有些(xie)較重的(de)(de)(de)(de)(de)塵粒(li)(li)便(bian)失去(qu)速度而沉(chen)降下來。進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)含(han)(han)塵氣(qi)體由于(yu)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通人高(gao)壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)(dian)暈現(xian)象(xiang)，使(shi)氣(qi)體電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)(de)氣(qi)體中存在大量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與(yu)進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)粉(fen)塵結合起來，使(shi)塵粒(li)(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵粒(li)(li)在電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)作(zuo)用下趨向(xiang)本(ben)設備陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設備采(cai)用負(fu)高(gao)壓制)和陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)子(zi)分別(bie)沉(chen)積(ji)在相應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過(guo)設備陰(yin)陽極(ji)(ji)(ji)振(zhen)打系統的(de)(de)(de)(de)(de)振(zhen)打，使(shi)沉(chen)積(ji)在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)(de)粉(fen)塵振(zhen)落，進(jin)人集灰斗 通過(guo)排灰裝(zhuang)置放出(chu)，回(hui)收(shou)有物料，被)凈(jing)(jing)化(hua)的(de)(de)(de)(de)(de)氣(qi)體排入大氣(qi)。

工作原理

靜電(dian)除(chu)塵(chen)器(qi)的(de)(de)工作原(yuan)理是利(li)用高壓(ya)電(dian)場(chang)使(shi)煙氣(qi)發生電(dian)離(li)，氣(qi)流中的(de)(de)粉(fen)塵(chen)荷電(dian)在電(dian)場(chang)作用下(xia)與氣(qi)流分離(li)。負(fu)極由(you)不同斷面(mian)形狀的(de)(de)金屬(shu)導(dao)線(xian)制成(cheng)(cheng)，叫放電(dian)電(dian)極。正極由(you)不同幾何形狀的(de)(de)金屬(shu)板制成(cheng)(cheng)，叫集(ji)塵(chen)電(dian)極。靜電(dian)除(chu)塵(chen)器(qi)的(de)(de)性能(neng)受粉(fen)塵(chen)性質、設備構(gou)造和煙氣(qi)流速等三個因素的(de)(de)影(ying)響。粉(fen)塵(chen)的(de)(de)比電(dian)阻(zu)是評價導(dao)電(dian)性的(de)(de)指標，它對(dui)除(chu)塵(chen)效(xiao)率(lv)有直接的(de)(de)影(ying)響。比電(dian)阻(zu)過(guo)低，塵(chen)粒難以保持在集(ji)塵(chen)電(dian)極上(shang)，致使(shi)其重返(fan)氣(qi)流。比電(dian)阻(zu)過(guo)高，到達集(ji)塵(chen)電(dian)極的(de)(de)塵(chen)粒電(dian)荷不易放出(chu)，在塵(chen)層(ceng)之間形成(cheng)(cheng)電(dian)壓(ya)梯度會產生局部擊穿(chuan)和放電(dian)現象(xiang)。這些情況都會造成(cheng)(cheng)除(chu)塵(chen)效(xiao)率(lv)下(xia)降。

電(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)基(ji)本(ben)原理是利用(yong)電(dian)(dian)力捕(bu)(bu)集煙氣(qi)中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)，主要包括以下四個相互有(you)關的(de)(de)(de)物理過程: (1) 氣(qi)體(ti)的(de)(de)(de)電(dian)(dian)離(li)。(2) 粉(fen)(fen)塵(chen)(chen)的(de)(de)(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)(fen)塵(chen)(chen)向電(dian)(dian)極(ji)移動。(4) 荷(he)電(dian)(dian)粉(fen)(fen)塵(chen)(chen)的(de)(de)(de)捕(bu)(bu)集。
