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)除塵(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化法來收捕廢氣(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)，它的(de)(de)(de)(de)凈化工作上要是依(yi)靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉(chen)淀兩個系(xi)統(tong)來完成(cheng)的(de)(de)(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)進人(ren)氣(qi)(qi)(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)受(shou)到氣(qi)(qi)(qi)(qi)流(liu)(liu)分布板以及折流(liu)(liu)板的(de)(de)(de)(de)調整后(hou)(hou)，使(shi)(shi)氣(qi)(qi)(qi)(qi)流(liu)(liu)能(neng)較均勻地(di)進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場。在橫斷面擴(kuo)大(da)的(de)(de)(de)(de)作用下(xia)，氣(qi)(qi)(qi)(qi)流(liu)(liu)速度迅速降低，其(qi)中有(you)些較重(zhong)的(de)(de)(de)(de)塵(chen)(chen)粒(li)便失去速度而沉(chen)降下(xia)來。進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通人(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)(shi)氣(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后(hou)(hou)的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)中存在大(da)量(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和離子(zi)(zi)與進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)結合起來，使(shi)(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作用下(xia)趨向(xiang)本設備(bei)陽(yang)極(ji)(正極(ji)、本設備(bei)采用負(fu)高壓制(zhi))和陰極(ji)(負(fu)極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別沉(chen)積(ji)在相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，通過(guo)設備(bei)陰陽(yang)極(ji)振(zhen)打系(xi)統(tong)的(de)(de)(de)(de)振(zhen)打，使(shi)(shi)沉(chen)積(ji)在陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)振(zhen)落，進人(ren)集灰斗 通過(guo)排(pai)灰裝置放出，回收有(you)物料，被)凈化的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)排(pai)入大(da)氣(qi)(qi)(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)工作(zuo)原理是(shi)利用(yong)高壓電(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)離，氣流中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作(zuo)用(yong)下與氣流分離。負極(ji)(ji)(ji)(ji)由不同斷面形(xing)狀的(de)(de)(de)金(jin)屬(shu)(shu)導線(xian)制成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)。正極(ji)(ji)(ji)(ji)由不同幾何形(xing)狀的(de)(de)(de)金(jin)屬(shu)(shu)板(ban)制成，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)性能受粉塵(chen)(chen)(chen)(chen)性質、設備構(gou)造和(he)煙氣流速等三個因素的(de)(de)(de)影(ying)響。粉塵(chen)(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)性的(de)(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)(chen)效(xiao)率有(you)直接的(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，致使其重返氣流。比電(dian)(dian)(dian)阻(zu)過(guo)高，到達(da)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易放出，在(zai)塵(chen)(chen)(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)壓梯度(du)會(hui)產生局部擊(ji)穿(chuan)和(he)放電(dian)(dian)(dian)現(xian)象(xiang)。這些情況都會(hui)造成除(chu)塵(chen)(chen)(chen)(chen)效(xiao)率下降(jiang)。

電(dian)除塵(chen)器的基(ji)本原理(li)是利用(yong)電(dian)力捕集煙氣中的粉塵(chen)，主要包括以下(xia)四(si)個相互有(you)關的物理(li)過程: (1) 氣體(ti)的電(dian)離。(2) 粉塵(chen)的荷電(dian)。(3) 荷電(dian)粉塵(chen)向(xiang)電(dian)極移動。(4) 荷電(dian)粉塵(chen)的捕集。
