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)(dian)(dian)除(chu)塵(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收捕(bu)廢氣(qi)(qi)(qi)中(zhong)(zhong)的(de)(de)粉(fen)(fen)塵(chen)(chen)，它的(de)(de)凈(jing)化(hua)工作上(shang)要是依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)和(he)(he)沉(chen)(chen)淀兩個系(xi)統來(lai)完成的(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進(jin)人氣(qi)(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受到(dao)氣(qi)(qi)(qi)流分布板以及折流板的(de)(de)調整后(hou)(hou)，使氣(qi)(qi)(qi)流能較(jiao)均勻地進(jin)人電(dian)(dian)(dian)(dian)場(chang)。在橫(heng)斷面擴大(da)的(de)(de)作用(yong)下，氣(qi)(qi)(qi)流速(su)度(du)迅速(su)降低，其(qi)中(zhong)(zhong)有(you)些較(jiao)重(zhong)的(de)(de)塵(chen)(chen)粒便失去(qu)速(su)度(du)而沉(chen)(chen)降下來(lai)。進(jin)人電(dian)(dian)(dian)(dian)場(chang)的(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)通(tong)(tong)人高壓直流電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)離(li)(li)后(hou)(hou)的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中(zhong)(zhong)存在大(da)量的(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離(li)(li)子(zi)(zi)，這(zhe)些電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離(li)(li)子(zi)(zi)與進(jin)人電(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)(fen)塵(chen)(chen)結合起來(lai)，使塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用(yong)下趨向(xiang)本(ben)設(she)(she)備陽極(ji)(正極(ji)、本(ben)設(she)(she)備采用(yong)負高壓制)和(he)(he)陰極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)(zi)分別沉(chen)(chen)積(ji)在相應(ying)的(de)(de)電(dian)(dian)(dian)(dian)極(ji)上(shang)，通(tong)(tong)過(guo)設(she)(she)備陰陽極(ji)振打(da)(da)系(xi)統的(de)(de)振打(da)(da)，使沉(chen)(chen)積(ji)在陰陽電(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)粉(fen)(fen)塵(chen)(chen)振落，進(jin)人集灰(hui)斗(dou) 通(tong)(tong)過(guo)排灰(hui)裝置放出，回收有(you)物料，被)凈(jing)化(hua)的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排入(ru)大(da)氣(qi)(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)除塵(chen)器的(de)(de)(de)工作(zuo)原理是(shi)利用高(gao)壓電(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)離(li)，氣(qi)流(liu)(liu)中(zhong)的(de)(de)(de)粉(fen)(fen)塵(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作(zuo)用下(xia)與氣(qi)流(liu)(liu)分離(li)。負極(ji)由不(bu)(bu)同(tong)斷(duan)面形(xing)狀的(de)(de)(de)金(jin)屬(shu)導線制(zhi)成，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由不(bu)(bu)同(tong)幾(ji)何形(xing)狀的(de)(de)(de)金(jin)屬(shu)板制(zhi)成，叫(jiao)集塵(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除塵(chen)器的(de)(de)(de)性(xing)能受粉(fen)(fen)塵(chen)性(xing)質、設(she)備構(gou)造(zao)和煙氣(qi)流(liu)(liu)速(su)等三個因素的(de)(de)(de)影(ying)響。粉(fen)(fen)塵(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)阻(zu)是(shi)評價(jia)導電(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它對(dui)除塵(chen)效(xiao)率有直(zhi)接的(de)(de)(de)影(ying)響。比(bi)電(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)粒(li)難以保持在(zai)集塵(chen)電(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)流(liu)(liu)。比(bi)電(dian)(dian)(dian)阻(zu)過(guo)高(gao)，到達集塵(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)粒(li)電(dian)(dian)(dian)荷不(bu)(bu)易放出，在(zai)塵(chen)層(ceng)之間形(xing)成電(dian)(dian)(dian)壓梯度會(hui)產生局部擊穿(chuan)和放電(dian)(dian)(dian)現象(xiang)。這些情況都會(hui)造(zao)成除塵(chen)效(xiao)率下(xia)降。

電(dian)(dian)除塵(chen)器的(de)(de)(de)基(ji)本原(yuan)理(li)是(shi)利用電(dian)(dian)力捕(bu)集(ji)(ji)煙氣中(zhong)的(de)(de)(de)粉(fen)塵(chen)，主要包括以下四個相(xiang)互有關的(de)(de)(de)物理(li)過(guo)程: (1) 氣體(ti)的(de)(de)(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉(fen)塵(chen)的(de)(de)(de)捕(bu)集(ji)(ji)。
