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)除塵(chen)(chen)器是(shi)(shi)以(yi)靜電(dian)(dian)凈(jing)化法來收捕廢氣(qi)(qi)(qi)(qi)(qi)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)，它(ta)的(de)(de)凈(jing)化工(gong)作上要是(shi)(shi)依靠電(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)(he)沉淀兩個系統(tong)來完成的(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)進(jin)人氣(qi)(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)受到(dao)氣(qi)(qi)(qi)(qi)(qi)流分布板(ban)以(yi)及(ji)折(zhe)流板(ban)的(de)(de)調整后，使(shi)氣(qi)(qi)(qi)(qi)(qi)流能較均(jun)勻地進(jin)人電(dian)(dian)場。在橫斷面(mian)擴大(da)(da)(da)的(de)(de)作用下(xia)，氣(qi)(qi)(qi)(qi)(qi)流速度迅速降低，其中(zhong)有(you)些較重(zhong)的(de)(de)塵(chen)(chen)粒便(bian)失去速度而(er)沉降下(xia)來。進(jin)人電(dian)(dian)場的(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)暈(yun)極(ji)(ji)(ji)通人高壓直流電(dian)(dian)，則在電(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)離(li)，電(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)存在大(da)(da)(da)量的(de)(de)電(dian)(dian)子和(he)(he)離(li)子，這些電(dian)(dian)子和(he)(he)離(li)子與(yu)進(jin)人電(dian)(dian)場的(de)(de)粉(fen)塵(chen)(chen)結合(he)起(qi)來，使(shi)塵(chen)(chen)粒帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)場力(li)的(de)(de)作用下(xia)趨向本設備陽(yang)(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備采(cai)用負高壓制)和(he)(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)子分別沉積(ji)在相(xiang)應的(de)(de)電(dian)(dian)極(ji)(ji)(ji)上，通過設備陰陽(yang)(yang)極(ji)(ji)(ji)振(zhen)打系統(tong)的(de)(de)振(zhen)打，使(shi)沉積(ji)在陰陽(yang)(yang)電(dian)(dian)極(ji)(ji)(ji)上的(de)(de)粉(fen)塵(chen)(chen)振(zhen)落，進(jin)人集灰斗 通過排灰裝置放出(chu)，回收有(you)物料，被)凈(jing)化的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)排入大(da)(da)(da)氣(qi)(qi)(qi)(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)工(gong)作(zuo)原理是利用高壓(ya)電(dian)(dian)(dian)場(chang)使(shi)煙(yan)氣發生電(dian)(dian)(dian)離，氣流(liu)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)場(chang)作(zuo)用下與氣流(liu)分離。負極(ji)由不(bu)同斷面(mian)形狀的(de)(de)(de)(de)金屬導線(xian)制(zhi)成，叫(jiao)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同幾何形狀的(de)(de)(de)(de)金屬板制(zhi)成，叫(jiao)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)性能受粉塵(chen)(chen)(chen)(chen)性質、設備構造(zao)和(he)煙(yan)氣流(liu)速等(deng)三個因素的(de)(de)(de)(de)影響。粉塵(chen)(chen)(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性的(de)(de)(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)效率有直接的(de)(de)(de)(de)影響。比電(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)(chen)粒(li)難以保持在(zai)(zai)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致(zhi)使(shi)其重返氣流(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)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)荷不(bu)易放(fang)出(chu)，在(zai)(zai)塵(chen)(chen)(chen)(chen)層之(zhi)間形成電(dian)(dian)(dian)壓(ya)梯度會(hui)(hui)產(chan)生局部(bu)擊(ji)穿(chuan)和(he)放(fang)電(dian)(dian)(dian)現象。這些情況都會(hui)(hui)造(zao)成除塵(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)除塵(chen)器的(de)(de)基本原理(li)(li)是利用(yong)電(dian)(dian)力(li)捕集煙(yan)氣中的(de)(de)粉塵(chen)，主要包括(kuo)以下四個相互有關的(de)(de)物(wu)理(li)(li)過程: (1) 氣體的(de)(de)電(dian)(dian)離。(2) 粉塵(chen)的(de)(de)荷(he)(he)(he)電(dian)(dian)。(3) 荷(he)(he)(he)電(dian)(dian)粉塵(chen)向(xiang)電(dian)(dian)極(ji)移(yi)動(dong)。(4) 荷(he)(he)(he)電(dian)(dian)粉塵(chen)的(de)(de)捕集。
