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)除(chu)塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)凈化法來(lai)(lai)收(shou)捕廢氣(qi)中的(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)凈化工作上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和(he)沉(chen)淀(dian)兩(liang)個系統來(lai)(lai)完成的(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)進(jin)人(ren)氣(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)受(shou)到氣(qi)流(liu)(liu)分布板(ban)以及折流(liu)(liu)板(ban)的(de)(de)調整后，使氣(qi)流(liu)(liu)能較均勻地(di)進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷(duan)面擴大的(de)(de)作用(yong)下，氣(qi)流(liu)(liu)速度迅速降低，其(qi)中有些較重(zhong)的(de)(de)塵(chen)(chen)(chen)粒便失去速度而沉(chen)降下來(lai)(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通(tong)(tong)人(ren)高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現象，使氣(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)體(ti)(ti)中存在(zai)(zai)大量(liang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子，這些電(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子與(yu)進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)(lai)，使塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作用(yong)下趨向本(ben)設(she)備(bei)陽(yang)(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設(she)備(bei)采用(yong)負高壓制)和(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積(ji)在(zai)(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)(tong)過設(she)備(bei)陰陽(yang)(yang)極(ji)(ji)振打系統的(de)(de)振打，使沉(chen)積(ji)在(zai)(zai)陰陽(yang)(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉塵(chen)(chen)(chen)振落，進(jin)人(ren)集灰斗 通(tong)(tong)過排(pai)(pai)灰裝置放出(chu)，回收(shou)有物料，被)凈化的(de)(de)氣(qi)體(ti)(ti)排(pai)(pai)入大氣(qi)。

工作(zuo)原理

靜電(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)工作(zuo)原理是(shi)利用(yong)高(gao)壓電(dian)場使煙氣(qi)發生電(dian)離，氣(qi)流中的(de)(de)(de)粉(fen)塵(chen)(chen)荷電(dian)在電(dian)場作(zuo)用(yong)下(xia)與(yu)氣(qi)流分離。負(fu)極(ji)由不(bu)(bu)同斷面形狀的(de)(de)(de)金(jin)屬導(dao)(dao)線制(zhi)成(cheng)，叫(jiao)放電(dian)電(dian)極(ji)。正(zheng)極(ji)由不(bu)(bu)同幾何形狀的(de)(de)(de)金(jin)屬板制(zhi)成(cheng)，叫(jiao)集塵(chen)(chen)電(dian)極(ji)。靜電(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)性能受粉(fen)塵(chen)(chen)性質、設備構造和(he)煙氣(qi)流速等三個因素的(de)(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)(de)比電(dian)阻是(shi)評價導(dao)(dao)電(dian)性的(de)(de)(de)指標，它對(dui)除(chu)(chu)塵(chen)(chen)效率有直(zhi)接的(de)(de)(de)影響。比電(dian)阻過低，塵(chen)(chen)粒(li)難以保持在集塵(chen)(chen)電(dian)極(ji)上，致使其重(zhong)返(fan)氣(qi)流。比電(dian)阻過高(gao)，到達集塵(chen)(chen)電(dian)極(ji)的(de)(de)(de)塵(chen)(chen)粒(li)電(dian)荷不(bu)(bu)易放出，在塵(chen)(chen)層(ceng)之間形成(cheng)電(dian)壓梯度(du)會(hui)產(chan)生局部擊穿和(he)放電(dian)現(xian)象(xiang)。這些情況都會(hui)造成(cheng)除(chu)(chu)塵(chen)(chen)效率下(xia)降。

電(dian)(dian)(dian)除塵(chen)(chen)器(qi)的基本原理(li)是(shi)利用電(dian)(dian)(dian)力(li)捕(bu)集煙(yan)氣(qi)中的粉(fen)(fen)塵(chen)(chen)，主要包(bao)括以下(xia)四個相互(hu)有關的物理(li)過程: (1) 氣(qi)體(ti)的電(dian)(dian)(dian)離(li)。(2) 粉(fen)(fen)塵(chen)(chen)的荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉(fen)(fen)塵(chen)(chen)向電(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)粉(fen)(fen)塵(chen)(chen)的捕(bu)集。
