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)(dian)(dian)(dian)(dian)除塵(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化法來(lai)收(shou)(shou)捕廢氣(qi)(qi)中的(de)粉(fen)塵(chen)，它的(de)凈(jing)化工作(zuo)(zuo)上要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和沉淀兩(liang)個系(xi)統(tong)來(lai)完成的(de)，當含塵(chen)氣(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流(liu)分布板以及折流(liu)板的(de)調整后，使氣(qi)(qi)流(liu)能較(jiao)均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷(duan)面擴大(da)的(de)作(zuo)(zuo)用(yong)下(xia)，氣(qi)(qi)流(liu)速度迅速降低，其中有些較(jiao)重(zhong)的(de)塵(chen)粒(li)便失去速度而沉降下(xia)來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)含塵(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通(tong)(tong)人(ren)高(gao)壓直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現(xian)象(xiang)，使氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)氣(qi)(qi)體(ti)中存(cun)在(zai)大(da)量的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和離子，這些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和離子與(yu)進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)粉(fen)塵(chen)結(jie)合起來(lai)，使塵(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)作(zuo)(zuo)用(yong)下(xia)趨向本設備(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備(bei)采用(yong)負高(gao)壓制)和陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子分別(bie)沉積在(zai)相應的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通(tong)(tong)過設備(bei)陰陽(yang)極(ji)(ji)(ji)振打系(xi)統(tong)的(de)振打，使沉積在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)粉(fen)塵(chen)振落，進(jin)人(ren)集(ji)灰斗 通(tong)(tong)過排(pai)(pai)灰裝置(zhi)放出，回收(shou)(shou)有物料，被)凈(jing)化的(de)氣(qi)(qi)體(ti)排(pai)(pai)入大(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)工作(zuo)原理是(shi)利用高(gao)壓電(dian)(dian)(dian)(dian)場(chang)使(shi)煙氣發生電(dian)(dian)(dian)(dian)離，氣流(liu)(liu)中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣流(liu)(liu)分離。負極(ji)(ji)(ji)由不同斷(duan)面形狀的(de)(de)(de)金屬導線(xian)制(zhi)成，叫放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不同幾何形狀的(de)(de)(de)金屬板制(zhi)成，叫集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)性(xing)能受粉塵(chen)(chen)(chen)(chen)(chen)(chen)性(xing)質、設備構造(zao)和煙氣流(liu)(liu)速等(deng)三個因素的(de)(de)(de)影(ying)響(xiang)。粉塵(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它(ta)對除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)效率有(you)直接的(de)(de)(de)影(ying)響(xiang)。比(bi)電(dian)(dian)(dian)(dian)阻過(guo)(guo)低，塵(chen)(chen)(chen)(chen)(chen)(chen)粒(li)難以保(bao)持在(zai)集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，致使(shi)其重(zhong)返氣流(liu)(liu)。比(bi)電(dian)(dian)(dian)(dian)阻過(guo)(guo)高(gao)，到達集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷(he)不易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)(chen)(chen)層之(zhi)間形成電(dian)(dian)(dian)(dian)壓梯(ti)度會產生局部擊穿(chuan)和放(fang)電(dian)(dian)(dian)(dian)現(xian)象。這些情況(kuang)都會造(zao)成除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)(dian)除塵(chen)(chen)器的(de)基本原理是(shi)利用電(dian)(dian)(dian)力捕(bu)集煙氣(qi)中的(de)粉(fen)塵(chen)(chen)，主要包括以下四個相互有(you)關的(de)物理過(guo)程: (1) 氣(qi)體的(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)(dian)極移(yi)動。(4) 荷電(dian)(dian)(dian)粉(fen)塵(chen)(chen)的(de)捕(bu)集。
