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(wo)式靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)是(shi)(shi)以靜電(dian)(dian)(dian)凈(jing)化法來(lai)(lai)收捕廢(fei)氣中(zhong)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)凈(jing)化工作上要是(shi)(shi)依靠電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和沉淀兩個系統來(lai)(lai)完成(cheng)的(de)(de)(de)，當含塵(chen)(chen)(chen)氣體(ti)(ti)進人(ren)(ren)(ren)氣刺(ci)叭時，含塵(chen)(chen)(chen)氣體(ti)(ti)受到氣流(liu)(liu)分(fen)布板以及折(zhe)流(liu)(liu)板的(de)(de)(de)調整后(hou)，使氣流(liu)(liu)能較均勻地(di)進人(ren)(ren)(ren)電(dian)(dian)(dian)場。在(zai)橫(heng)斷面擴大(da)的(de)(de)(de)作用(yong)下，氣流(liu)(liu)速度迅速降低(di)，其中(zhong)有些較重(zhong)的(de)(de)(de)塵(chen)(chen)(chen)粒便(bian)失去速度而沉降下來(lai)(lai)。進人(ren)(ren)(ren)電(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)(chen)(chen)氣體(ti)(ti)由于電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人(ren)(ren)(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近(jin)產生電(dian)(dian)(dian)暈(yun)現象，使氣體(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后(hou)的(de)(de)(de)氣體(ti)(ti)中(zhong)存在(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)子(zi)和離子(zi)與進人(ren)(ren)(ren)電(dian)(dian)(dian)場的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結合起來(lai)(lai)，使塵(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)場力(li)的(de)(de)(de)作用(yong)下趨向(xiang)本(ben)設備(bei)(bei)陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設備(bei)(bei)采用(yong)負(fu)高壓制)和陰極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子(zi)分(fen)別沉積(ji)在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)上，通過設備(bei)(bei)陰陽極(ji)(ji)(ji)振(zhen)(zhen)打系統的(de)(de)(de)振(zhen)(zhen)打，使沉積(ji)在(zai)陰陽電(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)(zhen)落，進人(ren)(ren)(ren)集灰斗(dou) 通過排灰裝置放出，回收有物料，被)凈(jing)化的(de)(de)(de)氣體(ti)(ti)排入大(da)氣。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的工作原(yuan)理是利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)使煙(yan)氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流中的粉塵(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)作用下(xia)(xia)與(yu)氣(qi)流分離(li)。負極(ji)由不同(tong)斷面形狀(zhuang)的金屬導線(xian)制成，叫放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不同(tong)幾何形狀(zhuang)的金屬板制成，叫集塵(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)器的性(xing)(xing)能受粉塵(chen)(chen)(chen)(chen)(chen)性(xing)(xing)質(zhi)、設備構造和煙(yan)氣(qi)流速等(deng)三個因素的影(ying)響(xiang)。粉塵(chen)(chen)(chen)(chen)(chen)的比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)是評價導電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)(xing)的指(zhi)標，它對(dui)除塵(chen)(chen)(chen)(chen)(chen)效率有直接的影(ying)響(xiang)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過(guo)低，塵(chen)(chen)(chen)(chen)(chen)粒難以保(bao)持在(zai)集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重返(fan)氣(qi)流。比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過(guo)高(gao)，到(dao)達集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)(chen)層之間(jian)形成電(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)現象(xiang)。這些情況都(dou)會造成除塵(chen)(chen)(chen)(chen)(chen)效率下(xia)(xia)降(jiang)。
