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)除塵(chen)器是(shi)(shi)以靜(jing)電(dian)(dian)凈(jing)化(hua)法(fa)來收(shou)捕廢(fei)氣(qi)(qi)(qi)(qi)(qi)(qi)中(zhong)(zhong)的(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)凈(jing)化(hua)工作上(shang)要是(shi)(shi)依靠電(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)和(he)(he)沉(chen)淀兩個系統來完成(cheng)的(de)(de)(de)，當含塵(chen)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)進(jin)(jin)人(ren)氣(qi)(qi)(qi)(qi)(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)(qi)(qi)流分布板以及折流板的(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)(qi)(qi)(qi)流能(neng)較均勻地進(jin)(jin)人(ren)電(dian)(dian)場。在(zai)(zai)(zai)(zai)橫(heng)斷面(mian)擴(kuo)大的(de)(de)(de)作用下(xia)，氣(qi)(qi)(qi)(qi)(qi)(qi)流速度迅速降低，其中(zhong)(zhong)有(you)些(xie)(xie)較重的(de)(de)(de)塵(chen)粒便(bian)失去速度而沉(chen)降下(xia)來。進(jin)(jin)人(ren)電(dian)(dian)場的(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)由于電(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)通(tong)(tong)人(ren)高(gao)壓直流電(dian)(dian)，則在(zai)(zai)(zai)(zai)電(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)附近產(chan)生(sheng)電(dian)(dian)暈現象，使(shi)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)離，電(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)中(zhong)(zhong)存在(zai)(zai)(zai)(zai)大量的(de)(de)(de)電(dian)(dian)子和(he)(he)離子，這些(xie)(xie)電(dian)(dian)子和(he)(he)離子與進(jin)(jin)人(ren)電(dian)(dian)場的(de)(de)(de)粉(fen)塵(chen)結合起來，使(shi)塵(chen)粒帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵(chen)粒在(zai)(zai)(zai)(zai)電(dian)(dian)場力(li)的(de)(de)(de)作用下(xia)趨(qu)向本(ben)設備陽極(ji)(ji)(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)(ji)(ji)、本(ben)設備采用負(fu)高(gao)壓制)和(he)(he)陰(yin)極(ji)(ji)(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)子分別沉(chen)積在(zai)(zai)(zai)(zai)相應的(de)(de)(de)電(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)，通(tong)(tong)過(guo)設備陰(yin)陽極(ji)(ji)(ji)(ji)(ji)振打系統的(de)(de)(de)振打，使(shi)沉(chen)積在(zai)(zai)(zai)(zai)陰(yin)陽電(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)的(de)(de)(de)粉(fen)塵(chen)振落，進(jin)(jin)人(ren)集(ji)灰(hui)斗 通(tong)(tong)過(guo)排灰(hui)裝(zhuang)置(zhi)放出(chu)，回收(shou)有(you)物(wu)料，被)凈(jing)化(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)排入(ru)大氣(qi)(qi)(qi)(qi)(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)工作(zuo)原理是利用高壓電(dian)(dian)(dian)(dian)場使煙(yan)氣發生電(dian)(dian)(dian)(dian)離(li)，氣流中的(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作(zuo)用下與氣流分離(li)。負極由不同斷面(mian)形(xing)狀(zhuang)的(de)(de)金屬導線制(zhi)成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由不同幾何(he)形(xing)狀(zhuang)的(de)(de)金屬板制(zhi)成(cheng)，叫(jiao)集(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)性能受粉(fen)塵(chen)(chen)性質、設(she)備(bei)構造和煙(yan)氣流速等三個因(yin)素的(de)(de)影(ying)響(xiang)。粉(fen)塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)是評價(jia)導電(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除塵(chen)(chen)效率有直(zhi)接的(de)(de)影(ying)響(xiang)。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)粒難以保持在集(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極上，致使其(qi)重返氣流。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過高，到達集(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)層之間(jian)形(xing)成(cheng)電(dian)(dian)(dian)(dian)壓梯度會產(chan)生局部擊穿和放(fang)電(dian)(dian)(dian)(dian)現象。這些情況都會造成(cheng)除塵(chen)(chen)效率下降(jiang)。

電(dian)(dian)除(chu)塵(chen)(chen)器的(de)基本(ben)原理是(shi)利(li)用電(dian)(dian)力捕(bu)集煙(yan)氣(qi)中的(de)粉(fen)(fen)塵(chen)(chen)，主要(yao)包括以下(xia)四個(ge)相互(hu)有關的(de)物(wu)理過程: (1) 氣(qi)體(ti)的(de)電(dian)(dian)離。(2) 粉(fen)(fen)塵(chen)(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)(fen)塵(chen)(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉(fen)(fen)塵(chen)(chen)的(de)捕(bu)集。
