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)(dian)(dian)除塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)凈化法來(lai)收(shou)捕(bu)廢(fei)氣(qi)(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)(de)凈化工作(zuo)上要是依靠電(dian)(dian)(dian)暈極(ji)和(he)沉(chen)淀(dian)兩個系(xi)統(tong)(tong)來(lai)完成的(de)(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進(jin)(jin)人氣(qi)(qi)刺叭(ba)時(shi)，含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流(liu)分布板以及折流(liu)板的(de)(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)流(liu)能較均勻地進(jin)(jin)人電(dian)(dian)(dian)場(chang)(chang)。在橫(heng)斷面擴大(da)(da)的(de)(de)(de)(de)作(zuo)用(yong)下，氣(qi)(qi)流(liu)速(su)度迅速(su)降低，其中有些(xie)較重的(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)(li)便失去速(su)度而(er)沉(chen)降下來(lai)。進(jin)(jin)人電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)暈極(ji)通(tong)人高(gao)壓直流(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈極(ji)附(fu)近產生電(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)中存在大(da)(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)子和(he)離(li)(li)子，這些(xie)電(dian)(dian)(dian)子和(he)離(li)(li)子與進(jin)(jin)人電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結合起來(lai)，使(shi)(shi)塵(chen)(chen)(chen)粒(li)(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)(li)在電(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)作(zuo)用(yong)下趨向本設備陽(yang)極(ji)(正極(ji)、本設備采用(yong)負(fu)高(gao)壓制)和(he)陰極(ji)(負(fu)極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子分別沉(chen)積在相(xiang)應的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)上，通(tong)過設備陰陽(yang)極(ji)振(zhen)打系(xi)統(tong)(tong)的(de)(de)(de)(de)振(zhen)打，使(shi)(shi)沉(chen)積在陰陽(yang)電(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)落，進(jin)(jin)人集(ji)灰斗 通(tong)過排(pai)(pai)灰裝置放(fang)出，回(hui)收(shou)有物料，被(bei))凈化的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)排(pai)(pai)入(ru)大(da)(da)氣(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)工(gong)作(zuo)原理是利用高壓電(dian)(dian)(dian)場使(shi)煙(yan)氣發生(sheng)電(dian)(dian)(dian)離，氣流(liu)中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)在電(dian)(dian)(dian)場作(zuo)用下與氣流(liu)分離。負極(ji)由(you)不同斷(duan)面形狀(zhuang)的(de)金(jin)屬(shu)導線制(zhi)成，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同幾何形狀(zhuang)的(de)金(jin)屬(shu)板制(zhi)成，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設備(bei)構(gou)造和(he)煙(yan)氣流(liu)速等三(san)個因素的(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性(xing)的(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)(chen)效率有直接(jie)的(de)影響(xiang)。比電(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)(chen)粒難以(yi)保持(chi)在集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使(shi)其重返(fan)氣流(liu)。比電(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷(he)不易放(fang)出，在塵(chen)(chen)(chen)(chen)層(ceng)之間形成電(dian)(dian)(dian)壓梯(ti)度會產生(sheng)局部(bu)擊(ji)穿和(he)放(fang)電(dian)(dian)(dian)現(xian)象。這些情況(kuang)都會造成除(chu)塵(chen)(chen)(chen)(chen)效率下降。

電除塵(chen)器的(de)(de)基本原理是利用(yong)電力捕(bu)集煙氣中的(de)(de)粉塵(chen)，主(zhu)要包括以下四個相(xiang)互有關的(de)(de)物理過(guo)程: (1) 氣體(ti)的(de)(de)電離。(2) 粉塵(chen)的(de)(de)荷電。(3) 荷電粉塵(chen)向電極移動。(4) 荷電粉塵(chen)的(de)(de)捕(bu)集。
