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。

臥式靜電(dian)除塵(chen)(chen)(chen)(chen)(chen)器是(shi)以靜電(dian)凈(jing)化(hua)(hua)法來收捕廢氣(qi)(qi)中(zhong)(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)，它的(de)(de)(de)凈(jing)化(hua)(hua)工作(zuo)上(shang)要是(shi)依靠電(dian)暈極(ji)(ji)(ji)和(he)沉(chen)淀兩個系(xi)統來完成的(de)(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進人氣(qi)(qi)刺(ci)叭(ba)時，含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流分布板以及折流板的(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)流能較(jiao)均勻地進人電(dian)場(chang)(chang)。在(zai)(zai)橫斷(duan)面擴大的(de)(de)(de)作(zuo)用下，氣(qi)(qi)流速度(du)迅速降(jiang)低，其中(zhong)(zhong)有些(xie)較(jiao)重的(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒(li)便失(shi)去速度(du)而沉(chen)降(jiang)下來。進人電(dian)場(chang)(chang)的(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)暈極(ji)(ji)(ji)通人高壓(ya)直流電(dian)，則(ze)在(zai)(zai)電(dian)暈極(ji)(ji)(ji)附近產生(sheng)電(dian)暈現象，使(shi)(shi)氣(qi)(qi)體(ti)(ti)電(dian)離(li)，電(dian)離(li)后的(de)(de)(de)氣(qi)(qi)體(ti)(ti)中(zhong)(zhong)存在(zai)(zai)大量的(de)(de)(de)電(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)，這些(xie)電(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)與進人電(dian)場(chang)(chang)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)結合起來，使(shi)(shi)塵(chen)(chen)(chen)(chen)(chen)粒(li)帶電(dian)，帶電(dian)塵(chen)(chen)(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)場(chang)(chang)力的(de)(de)(de)作(zuo)用下趨向本設備陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備采用負(fu)高壓(ya)制)和(he)陰極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出(chu)電(dian)子(zi)(zi)分別沉(chen)積(ji)在(zai)(zai)相應的(de)(de)(de)電(dian)極(ji)(ji)(ji)上(shang)，通過設備陰陽(yang)極(ji)(ji)(ji)振(zhen)(zhen)打(da)(da)系(xi)統的(de)(de)(de)振(zhen)(zhen)打(da)(da)，使(shi)(shi)沉(chen)積(ji)在(zai)(zai)陰陽(yang)電(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)振(zhen)(zhen)落，進人集(ji)灰斗 通過排灰裝(zhuang)置放出(chu)，回收有物料(liao)，被)凈(jing)化(hua)(hua)的(de)(de)(de)氣(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)工作原(yuan)理是(shi)利(li)用(yong)高壓(ya)電(dian)(dian)(dian)場使煙氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作用(yong)下與(yu)氣(qi)(qi)流(liu)分離。負極(ji)(ji)由不(bu)(bu)同斷面形狀的(de)(de)(de)金(jin)屬(shu)導線(xian)制成(cheng)(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)(bu)同幾何形狀的(de)(de)(de)金(jin)屬(shu)板(ban)制成(cheng)(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設備構造和煙氣(qi)(qi)流(liu)速等三個因(yin)素的(de)(de)(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)效率有直接的(de)(de)(de)影響。比電(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)(chen)粒(li)難以保持在(zai)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致(zhi)使其重返氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)阻(zu)過(guo)高，到達(da)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)荷(he)不(bu)(bu)易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)層之間(jian)形成(cheng)(cheng)電(dian)(dian)(dian)壓(ya)梯度會產生(sheng)局部(bu)擊(ji)穿和放(fang)電(dian)(dian)(dian)現象。這些(xie)情況(kuang)都會造成(cheng)(cheng)除塵(chen)(chen)(chen)(chen)效率下降(jiang)。

電(dian)(dian)(dian)除塵(chen)(chen)器的(de)基本(ben)原理(li)是(shi)利(li)用(yong)電(dian)(dian)(dian)力捕(bu)集煙氣(qi)中(zhong)的(de)粉塵(chen)(chen)，主(zhu)要包(bao)括(kuo)以(yi)下四個相(xiang)互有(you)關的(de)物理(li)過程: (1) 氣(qi)體(ti)的(de)電(dian)(dian)(dian)離。(2) 粉塵(chen)(chen)的(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)(dian)極(ji)移動。(4) 荷電(dian)(dian)(dian)粉塵(chen)(chen)的(de)捕(bu)集。
