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(shi)靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)凈化法(fa)來收(shou)(shou)捕(bu)廢氣(qi)(qi)中(zhong)的(de)(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)(de)凈化工(gong)作(zuo)上(shang)(shang)要是依靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和沉淀兩個系統(tong)來完成的(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體(ti)進(jin)人(ren)(ren)氣(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流(liu)(liu)分布板(ban)以及折(zhe)流(liu)(liu)板(ban)的(de)(de)(de)調(diao)整(zheng)后，使氣(qi)(qi)流(liu)(liu)能較均(jun)勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)。在橫斷(duan)面擴(kuo)大的(de)(de)(de)作(zuo)用(yong)(yong)下(xia)(xia)(xia)，氣(qi)(qi)流(liu)(liu)速度迅速降(jiang)低，其中(zhong)有(you)些較重的(de)(de)(de)塵(chen)(chen)粒(li)便失去速度而沉降(jiang)下(xia)(xia)(xia)來。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通人(ren)(ren)高(gao)壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)體(ti)中(zhong)存在大量(liang)的(de)(de)(de)電(dian)(dian)(dian)(dian)子和離子，這些電(dian)(dian)(dian)(dian)子和離子與進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉(fen)塵(chen)(chen)結合(he)起來，使塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)作(zuo)用(yong)(yong)下(xia)(xia)(xia)趨向本(ben)設(she)備陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設(she)備采用(yong)(yong)負(fu)高(gao)壓制)和陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分別沉積在相(xiang)應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)，通過設(she)備陰(yin)陽(yang)極(ji)(ji)(ji)振打系統(tong)的(de)(de)(de)振打，使沉積在陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)的(de)(de)(de)粉(fen)塵(chen)(chen)振落，進(jin)人(ren)(ren)集灰斗(dou) 通過排灰裝置(zhi)放出，回收(shou)(shou)有(you)物料，被)凈化的(de)(de)(de)氣(qi)(qi)體(ti)排入大氣(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)工作(zuo)原理是利用高壓電(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作(zuo)用下與(yu)氣(qi)(qi)流(liu)分離。負(fu)極(ji)(ji)(ji)由不同(tong)(tong)斷(duan)面形狀(zhuang)的(de)(de)(de)(de)金屬(shu)導線制成(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正(zheng)極(ji)(ji)(ji)由不同(tong)(tong)幾何形狀(zhuang)的(de)(de)(de)(de)金屬(shu)板(ban)制成(cheng)，叫(jiao)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)性能受(shou)粉(fen)塵(chen)(chen)(chen)(chen)性質(zhi)、設備構造和煙氣(qi)(qi)流(liu)速等(deng)三個(ge)因素的(de)(de)(de)(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)性的(de)(de)(de)(de)指(zhi)標，它對除(chu)塵(chen)(chen)(chen)(chen)效率有直(zhi)接的(de)(de)(de)(de)影響。比電(dian)(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，致(zhi)使其重返(fan)氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)阻過(guo)高，到(dao)達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易放出(chu)，在塵(chen)(chen)(chen)(chen)層(ceng)之(zhi)間(jian)形成(cheng)電(dian)(dian)(dian)(dian)壓梯度會產(chan)生局(ju)部擊穿和放電(dian)(dian)(dian)(dian)現象。這(zhe)些情況都會造成(cheng)除(chu)塵(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)(dian)除塵(chen)器的(de)(de)基本原理(li)是(shi)利用電(dian)(dian)(dian)力捕集煙氣中的(de)(de)粉(fen)塵(chen)，主要包括以下四(si)個相(xiang)互有關的(de)(de)物(wu)理(li)過程: (1) 氣體(ti)的(de)(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)(de)荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)(dian)極移動(dong)。(4) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)的(de)(de)捕集。
