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(shi)靜電(dian)(dian)除(chu)塵(chen)(chen)器是(shi)以(yi)靜電(dian)(dian)凈(jing)化(hua)法(fa)來(lai)(lai)(lai)收捕(bu)廢氣(qi)(qi)(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)凈(jing)化(hua)工(gong)作(zuo)上要(yao)是(shi)依靠電(dian)(dian)暈(yun)極(ji)(ji)和沉(chen)淀兩個系(xi)統來(lai)(lai)(lai)完成的(de)(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)進(jin)人氣(qi)(qi)(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)(qi)(qi)流(liu)(liu)分布板(ban)以(yi)及折流(liu)(liu)板(ban)的(de)(de)(de)調(diao)整后(hou)，使氣(qi)(qi)(qi)(qi)流(liu)(liu)能較均勻地進(jin)人電(dian)(dian)場。在橫斷面擴大的(de)(de)(de)作(zuo)用下，氣(qi)(qi)(qi)(qi)流(liu)(liu)速度迅速降(jiang)低，其中有(you)些較重的(de)(de)(de)塵(chen)(chen)粒(li)(li)便失去速度而(er)沉(chen)降(jiang)下來(lai)(lai)(lai)。進(jin)人電(dian)(dian)場的(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)暈(yun)極(ji)(ji)通人高(gao)(gao)壓直流(liu)(liu)電(dian)(dian)，則(ze)在電(dian)(dian)暈(yun)極(ji)(ji)附近(jin)產生電(dian)(dian)暈(yun)現(xian)象，使氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)離(li)(li)，電(dian)(dian)離(li)(li)后(hou)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)中存(cun)在大量的(de)(de)(de)電(dian)(dian)子(zi)和離(li)(li)子(zi)，這(zhe)些電(dian)(dian)子(zi)和離(li)(li)子(zi)與進(jin)人電(dian)(dian)場的(de)(de)(de)粉塵(chen)(chen)結合起來(lai)(lai)(lai)，使塵(chen)(chen)粒(li)(li)帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)粒(li)(li)在電(dian)(dian)場力(li)的(de)(de)(de)作(zuo)用下趨(qu)向(xiang)本設(she)備(bei)陽(yang)極(ji)(ji)(正(zheng)極(ji)(ji)、本設(she)備(bei)采用負高(gao)(gao)壓制(zhi))和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)子(zi)分別沉(chen)積(ji)在相應的(de)(de)(de)電(dian)(dian)極(ji)(ji)上，通過(guo)設(she)備(bei)陰陽(yang)極(ji)(ji)振(zhen)打(da)系(xi)統的(de)(de)(de)振(zhen)打(da)，使沉(chen)積(ji)在陰陽(yang)電(dian)(dian)極(ji)(ji)上的(de)(de)(de)粉塵(chen)(chen)振(zhen)落，進(jin)人集灰(hui)斗(dou) 通過(guo)排(pai)(pai)灰(hui)裝(zhuang)置放出(chu)，回收有(you)物料，被)凈(jing)化(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)排(pai)(pai)入大氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)工作原(yuan)理是利用高壓電(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)(liu)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作用下與氣(qi)流(liu)(liu)分離。負(fu)極(ji)(ji)由不同(tong)斷面形(xing)狀(zhuang)的(de)(de)(de)(de)金(jin)屬導線(xian)制成，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同(tong)幾何形(xing)狀(zhuang)的(de)(de)(de)(de)金(jin)屬板制成，叫(jiao)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)性(xing)能受粉塵(chen)(chen)(chen)(chen)性(xing)質、設(she)備構造和煙氣(qi)流(liu)(liu)速等三個因素的(de)(de)(de)(de)影響(xiang)。粉塵(chen)(chen)(chen)(chen)的(de)(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)效率(lv)有直(zhi)接的(de)(de)(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難以保持(chi)在集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使(shi)其重返(fan)氣(qi)流(liu)(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過高，到(dao)達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)(chen)(chen)層(ceng)之間形(xing)成電(dian)(dian)(dian)(dian)(dian)壓梯度(du)會(hui)(hui)產生(sheng)局(ju)部擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都(dou)會(hui)(hui)造成除塵(chen)(chen)(chen)(chen)效率(lv)下降(jiang)。

電(dian)除塵(chen)器的(de)基本原(yuan)理(li)是利用電(dian)力捕集煙氣中的(de)粉(fen)塵(chen)，主要包括以下四個相互有關(guan)的(de)物理(li)過程: (1) 氣體(ti)的(de)電(dian)離。(2) 粉(fen)塵(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵(chen)向電(dian)極移動。(4) 荷(he)電(dian)粉(fen)塵(chen)的(de)捕集。
