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)除塵(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)凈化(hua)法來(lai)收捕廢氣中(zhong)的(de)(de)粉(fen)塵(chen)，它(ta)的(de)(de)凈化(hua)工作上要是(shi)依靠(kao)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)和(he)(he)沉淀兩(liang)個(ge)系(xi)統來(lai)完(wan)成的(de)(de)，當含(han)塵(chen)氣體(ti)進(jin)人(ren)(ren)(ren)氣刺叭(ba)時(shi)，含(han)塵(chen)氣體(ti)受到氣流(liu)(liu)分(fen)布板以及折流(liu)(liu)板的(de)(de)調整后(hou)，使氣流(liu)(liu)能較(jiao)均(jun)勻(yun)地進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面(mian)擴大的(de)(de)作用下(xia)(xia)，氣流(liu)(liu)速度(du)(du)迅速降低，其中(zhong)有些較(jiao)重(zhong)的(de)(de)塵(chen)粒(li)便失去速度(du)(du)而沉降下(xia)(xia)來(lai)。進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)含(han)塵(chen)氣體(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)通人(ren)(ren)(ren)高(gao)壓(ya)直流(liu)(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)暈現象，使氣體(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后(hou)的(de)(de)氣體(ti)中(zhong)存(cun)在(zai)大量的(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離子(zi)(zi)，這些電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離子(zi)(zi)與進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)結合起來(lai)，使塵(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用下(xia)(xia)趨向本設備陽(yang)極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設備采用負(fu)高(gao)壓(ya)制)和(he)(he)陰極(ji)(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)子(zi)(zi)分(fen)別沉積(ji)在(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，通過設備陰陽(yang)極(ji)(ji)(ji)(ji)振(zhen)打系(xi)統的(de)(de)振(zhen)打，使沉積(ji)在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上的(de)(de)粉(fen)塵(chen)振(zhen)落，進(jin)人(ren)(ren)(ren)集灰斗 通過排(pai)灰裝置放出(chu)，回(hui)收有物料，被)凈化(hua)的(de)(de)氣體(ti)排(pai)入大氣。

工作(zuo)原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)工作原理是利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)(qi)發生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)(qi)流中的(de)(de)粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場作用下(xia)與(yu)氣(qi)(qi)流分離。負(fu)極(ji)由(you)不同斷面(mian)形狀的(de)(de)金(jin)屬導(dao)線(xian)制(zhi)成(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由(you)不同幾何形狀的(de)(de)金(jin)屬板制(zhi)成(cheng)，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)性能受粉塵(chen)(chen)性質、設備構(gou)造和煙氣(qi)(qi)流速等(deng)三個因素的(de)(de)影響(xiang)。粉塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻是評價(jia)導(dao)電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除(chu)塵(chen)(chen)效(xiao)率(lv)有直接的(de)(de)影響(xiang)。比電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致(zhi)使(shi)其重返氣(qi)(qi)流。比電(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到達(da)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不易放出，在(zai)塵(chen)(chen)層之(zhi)間形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產生局(ju)部擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成(cheng)除(chu)塵(chen)(chen)效(xiao)率(lv)下(xia)降。

電(dian)除塵(chen)(chen)器的(de)基本原(yuan)理(li)是利(li)用電(dian)力捕(bu)(bu)集煙氣(qi)中的(de)粉(fen)塵(chen)(chen)，主要包括(kuo)以下四(si)個相互有關(guan)的(de)物理(li)過(guo)程: (1) 氣(qi)體的(de)電(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)荷(he)(he)電(dian)。(3) 荷(he)(he)電(dian)粉(fen)塵(chen)(chen)向電(dian)極(ji)移動。(4) 荷(he)(he)電(dian)粉(fen)塵(chen)(chen)的(de)捕(bu)(bu)集。
