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)(dian)(dian)(dian)除塵(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化法來收捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)(de)凈化工作(zuo)上(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和沉(chen)淀兩個系(xi)統來完(wan)成(cheng)的(de)(de)(de)(de)，當含(han)塵(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)進人(ren)氣(qi)(qi)(qi)刺叭時(shi)，含(han)塵(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)受(shou)到氣(qi)(qi)(qi)流分布板(ban)以(yi)及折流板(ban)的(de)(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)(qi)流能(neng)較(jiao)均勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)橫斷面擴大的(de)(de)(de)(de)作(zuo)用(yong)下(xia)(xia)，氣(qi)(qi)(qi)流速(su)(su)度迅速(su)(su)降(jiang)低，其中(zhong)有些較(jiao)重的(de)(de)(de)(de)塵(chen)粒便(bian)失去速(su)(su)度而沉(chen)降(jiang)下(xia)(xia)來。進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)含(han)塵(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通(tong)(tong)人(ren)高壓直流電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近(jin)產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現象，使(shi)(shi)氣(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)中(zhong)存在(zai)大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和離(li)子，這些電(dian)(dian)(dian)(dian)(dian)(dian)子和離(li)子與進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)粉(fen)塵(chen)結合起來，使(shi)(shi)塵(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)作(zuo)用(yong)下(xia)(xia)趨向本設備陽(yang)(yang)極(ji)(ji)(正極(ji)(ji)、本設備采用(yong)負高壓制)和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子分別(bie)沉(chen)積(ji)在(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)(tong)過設備陰陽(yang)(yang)極(ji)(ji)振打系(xi)統的(de)(de)(de)(de)振打，使(shi)(shi)沉(chen)積(ji)在(zai)陰陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)(de)粉(fen)塵(chen)振落，進人(ren)集灰斗(dou) 通(tong)(tong)過排(pai)(pai)灰裝置放出，回收有物料，被)凈化的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)排(pai)(pai)入大氣(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)除塵(chen)(chen)器(qi)的(de)(de)工(gong)作(zuo)原理是(shi)利(li)用高壓(ya)電(dian)場使煙(yan)氣發(fa)生電(dian)離(li)，氣流中的(de)(de)粉塵(chen)(chen)荷(he)電(dian)在電(dian)場作(zuo)用下(xia)與(yu)氣流分離(li)。負極(ji)由不同(tong)(tong)斷面(mian)形狀的(de)(de)金(jin)屬導(dao)線制(zhi)成(cheng)，叫(jiao)放(fang)電(dian)電(dian)極(ji)。正極(ji)由不同(tong)(tong)幾何形狀的(de)(de)金(jin)屬板制(zhi)成(cheng)，叫(jiao)集塵(chen)(chen)電(dian)極(ji)。靜電(dian)除塵(chen)(chen)器(qi)的(de)(de)性能受粉塵(chen)(chen)性質、設備構造和煙(yan)氣流速等三(san)個因素的(de)(de)影響。粉塵(chen)(chen)的(de)(de)比(bi)電(dian)阻(zu)是(shi)評價導(dao)電(dian)性的(de)(de)指標，它對除塵(chen)(chen)效(xiao)率有(you)直(zhi)接的(de)(de)影響。比(bi)電(dian)阻(zu)過低，塵(chen)(chen)粒難以(yi)保持在集塵(chen)(chen)電(dian)極(ji)上，致使其重返氣流。比(bi)電(dian)阻(zu)過高，到達集塵(chen)(chen)電(dian)極(ji)的(de)(de)塵(chen)(chen)粒電(dian)荷(he)不易放(fang)出，在塵(chen)(chen)層之(zhi)間形成(cheng)電(dian)壓(ya)梯(ti)度(du)會產(chan)生局部擊(ji)穿(chuan)和放(fang)電(dian)現象。這些情況都(dou)會造成(cheng)除塵(chen)(chen)效(xiao)率下(xia)降。

電除塵(chen)器(qi)的基(ji)本原理是(shi)利用電力捕集煙(yan)氣中(zhong)的粉(fen)(fen)塵(chen)，主要包括以下四個相互有關的物理過程: (1) 氣體的電離。(2) 粉(fen)(fen)塵(chen)的荷(he)電。(3) 荷(he)電粉(fen)(fen)塵(chen)向(xiang)電極(ji)移動。(4) 荷(he)電粉(fen)(fen)塵(chen)的捕集。
