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)(jing)電(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)是(shi)以靜(jing)(jing)電(dian)(dian)凈化法來收捕(bu)廢氣(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)凈化工作(zuo)上要是(shi)依靠電(dian)(dian)暈(yun)極(ji)(ji)和(he)沉淀(dian)兩個(ge)系統來完(wan)成(cheng)的(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體進人氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體受(shou)到氣(qi)(qi)(qi)流分(fen)布板(ban)(ban)以及折流板(ban)(ban)的(de)(de)(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)(qi)流能較(jiao)均(jun)勻地(di)進人電(dian)(dian)場。在(zai)(zai)橫斷面擴(kuo)大的(de)(de)(de)(de)(de)作(zuo)用下，氣(qi)(qi)(qi)流速(su)度迅(xun)速(su)降(jiang)低，其中(zhong)有(you)些較(jiao)重(zhong)的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)(li)便失去(qu)速(su)度而沉降(jiang)下來。進人電(dian)(dian)場的(de)(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體由于電(dian)(dian)暈(yun)極(ji)(ji)通人高(gao)壓(ya)直(zhi)流電(dian)(dian)，則(ze)在(zai)(zai)電(dian)(dian)暈(yun)極(ji)(ji)附近產生電(dian)(dian)暈(yun)現象，使(shi)(shi)氣(qi)(qi)(qi)體電(dian)(dian)離，電(dian)(dian)離后的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體中(zhong)存在(zai)(zai)大量的(de)(de)(de)(de)(de)電(dian)(dian)子和(he)離子，這些電(dian)(dian)子和(he)離子與進人電(dian)(dian)場的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)結合起來，使(shi)(shi)塵(chen)(chen)(chen)(chen)粒(li)(li)帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)(li)在(zai)(zai)電(dian)(dian)場力的(de)(de)(de)(de)(de)作(zuo)用下趨向本(ben)(ben)設(she)備陽(yang)極(ji)(ji)(正(zheng)極(ji)(ji)、本(ben)(ben)設(she)備采用負高(gao)壓(ya)制)和(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)子分(fen)別沉積(ji)在(zai)(zai)相(xiang)應的(de)(de)(de)(de)(de)電(dian)(dian)極(ji)(ji)上，通過(guo)設(she)備陰陽(yang)極(ji)(ji)振(zhen)打(da)(da)系統的(de)(de)(de)(de)(de)振(zhen)打(da)(da)，使(shi)(shi)沉積(ji)在(zai)(zai)陰陽(yang)電(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)振(zhen)落，進人集灰(hui)斗 通過(guo)排灰(hui)裝置放(fang)出，回收有(you)物料，被)凈化的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體排入大氣(qi)(qi)(qi)。

工作原理(li)

靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的工作原理是(shi)利(li)用(yong)高壓電(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)發生(sheng)電(dian)(dian)(dian)離(li)，氣(qi)流(liu)(liu)中的粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)作用(yong)下與(yu)氣(qi)流(liu)(liu)分離(li)。負極由(you)不同斷面(mian)形狀的金屬導線制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由(you)不同幾何(he)形狀的金屬板(ban)制(zhi)成(cheng)，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的性(xing)能(neng)受(shou)粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質(zhi)、設備構造和(he)煙(yan)氣(qi)流(liu)(liu)速(su)等三個因素的影(ying)(ying)響。粉(fen)塵(chen)(chen)(chen)(chen)的比電(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)性(xing)的指(zhi)標，它對除(chu)塵(chen)(chen)(chen)(chen)效率有(you)直接(jie)的影(ying)(ying)響。比電(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極上，致使其重返氣(qi)流(liu)(liu)。比電(dian)(dian)(dian)阻過高，到(dao)達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極的塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)層(ceng)之間形成(cheng)電(dian)(dian)(dian)壓梯(ti)度(du)會(hui)(hui)產生(sheng)局部(bu)擊穿(chuan)和(he)放(fang)電(dian)(dian)(dian)現象。這些情況都會(hui)(hui)造成(cheng)除(chu)塵(chen)(chen)(chen)(chen)效率下降。

電除塵(chen)(chen)器的(de)(de)基本原理是利用電力捕集(ji)煙氣中的(de)(de)粉(fen)塵(chen)(chen)，主要包括以下四個相互有關的(de)(de)物理過程(cheng): (1) 氣體(ti)的(de)(de)電離。(2) 粉(fen)塵(chen)(chen)的(de)(de)荷電。(3) 荷電粉(fen)塵(chen)(chen)向電極移動。(4) 荷電粉(fen)塵(chen)(chen)的(de)(de)捕集(ji)。
