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)(dian)(dian)除塵(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)(dian)凈(jing)化法來(lai)(lai)(lai)收捕廢氣(qi)(qi)(qi)中的(de)粉(fen)塵(chen)，它的(de)凈(jing)化工作上(shang)要(yao)是(shi)依(yi)靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)沉(chen)淀兩個系統來(lai)(lai)(lai)完成的(de)，當含(han)塵(chen)氣(qi)(qi)(qi)體(ti)進(jin)人(ren)(ren)氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)(liu)分布板以及(ji)折流(liu)(liu)板的(de)調整后，使(shi)氣(qi)(qi)(qi)流(liu)(liu)能(neng)較(jiao)均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場。在(zai)橫斷(duan)面擴大的(de)作用下，氣(qi)(qi)(qi)流(liu)(liu)速度迅速降(jiang)低，其中有些較(jiao)重的(de)塵(chen)粒便失去速度而沉(chen)降(jiang)下來(lai)(lai)(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)含(han)塵(chen)氣(qi)(qi)(qi)體(ti)由(you)于電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通人(ren)(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)暈現象，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)氣(qi)(qi)(qi)體(ti)中存在(zai)大量的(de)電(dian)(dian)(dian)(dian)子和(he)離(li)子，這(zhe)些電(dian)(dian)(dian)(dian)子和(he)離(li)子與進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)粉(fen)塵(chen)結(jie)合起來(lai)(lai)(lai)，使(shi)塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)粒在(zai)電(dian)(dian)(dian)(dian)場力的(de)作用下趨(qu)向(xiang)本設(she)備(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設(she)備(bei)采用負高壓制)和(he)陰(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分別(bie)沉(chen)積在(zai)相應的(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通過設(she)備(bei)陰(yin)陽(yang)極(ji)(ji)(ji)振(zhen)打系統的(de)振(zhen)打，使(shi)沉(chen)積在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)粉(fen)塵(chen)振(zhen)落(luo)，進(jin)人(ren)(ren)集(ji)灰斗(dou) 通過排灰裝(zhuang)置放出，回(hui)收有物料(liao)，被)凈(jing)化的(de)氣(qi)(qi)(qi)體(ti)排入大氣(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)工作(zuo)原理是利用(yong)高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場作(zuo)用(yong)下與氣(qi)流分離。負極(ji)由不(bu)同斷面形狀(zhuang)的(de)(de)(de)(de)金屬(shu)導(dao)(dao)線(xian)制成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同幾何形狀(zhuang)的(de)(de)(de)(de)金屬(shu)板制成(cheng)，叫集塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)性(xing)質、設備構造和煙(yan)氣(qi)流速等三(san)個因素的(de)(de)(de)(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)(dian)阻是評價導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)指標，它(ta)對除塵(chen)(chen)(chen)(chen)(chen)(chen)效率有直接的(de)(de)(de)(de)影響(xiang)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)(chen)(chen)(chen)粒(li)難以保持在(zai)集塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致(zhi)使其重返(fan)氣(qi)流。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過(guo)高(gao)，到(dao)達集塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)荷不(bu)易(yi)放出，在(zai)塵(chen)(chen)(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯(ti)度會(hui)產生(sheng)局部擊穿和放電(dian)(dian)(dian)(dian)(dian)(dian)現象。這(zhe)些(xie)情況都(dou)會(hui)造成(cheng)除塵(chen)(chen)(chen)(chen)(chen)(chen)效率下降。

電除塵(chen)(chen)器的(de)基本(ben)原理是利用(yong)電力(li)捕集煙氣中的(de)粉塵(chen)(chen)，主要包括以下(xia)四個(ge)相(xiang)互(hu)有關的(de)物理過程(cheng): (1) 氣體的(de)電離。(2) 粉塵(chen)(chen)的(de)荷電。(3) 荷電粉塵(chen)(chen)向電極移動。(4) 荷電粉塵(chen)(chen)的(de)捕集。
