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)式靜(jing)電(dian)(dian)除塵器是(shi)(shi)以(yi)靜(jing)電(dian)(dian)凈化法(fa)來(lai)收捕廢氣(qi)(qi)(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)(de)粉塵，它的(de)(de)(de)(de)(de)(de)凈化工作(zuo)(zuo)上要是(shi)(shi)依靠電(dian)(dian)暈極(ji)(ji)(ji)和沉淀(dian)兩個系(xi)(xi)統來(lai)完成的(de)(de)(de)(de)(de)(de)，當含塵氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)進人(ren)(ren)氣(qi)(qi)(qi)(qi)(qi)(qi)刺叭時，含塵氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)(qi)(qi)流(liu)分布(bu)板以(yi)及折流(liu)板的(de)(de)(de)(de)(de)(de)調(diao)整后(hou)，使(shi)氣(qi)(qi)(qi)(qi)(qi)(qi)流(liu)能較(jiao)(jiao)均(jun)勻地進人(ren)(ren)電(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)(de)(de)(de)(de)(de)作(zuo)(zuo)用下(xia)，氣(qi)(qi)(qi)(qi)(qi)(qi)流(liu)速度(du)迅速降(jiang)(jiang)低，其中(zhong)有些較(jiao)(jiao)重的(de)(de)(de)(de)(de)(de)塵粒(li)便(bian)失去(qu)速度(du)而沉降(jiang)(jiang)下(xia)來(lai)。進人(ren)(ren)電(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)含塵氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)由于電(dian)(dian)暈極(ji)(ji)(ji)通人(ren)(ren)高壓直(zhi)流(liu)電(dian)(dian)，則在(zai)電(dian)(dian)暈極(ji)(ji)(ji)附(fu)近產生(sheng)電(dian)(dian)暈現(xian)象(xiang)，使(shi)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)離(li)，電(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)中(zhong)存在(zai)大(da)量的(de)(de)(de)(de)(de)(de)電(dian)(dian)子(zi)和離(li)子(zi)，這些電(dian)(dian)子(zi)和離(li)子(zi)與進人(ren)(ren)電(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)粉塵結合起來(lai)，使(shi)塵粒(li)帶(dai)(dai)電(dian)(dian)，帶(dai)(dai)電(dian)(dian)塵粒(li)在(zai)電(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)(de)作(zuo)(zuo)用下(xia)趨向本設備陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備采(cai)用負(fu)高壓制)和陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋(shi)放(fang)出電(dian)(dian)子(zi)分別(bie)沉積在(zai)相應的(de)(de)(de)(de)(de)(de)電(dian)(dian)極(ji)(ji)(ji)上，通過(guo)設備陰(yin)陽極(ji)(ji)(ji)振打(da)系(xi)(xi)統的(de)(de)(de)(de)(de)(de)振打(da)，使(shi)沉積在(zai)陰(yin)陽電(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)(de)(de)粉塵振落，進人(ren)(ren)集灰斗(dou) 通過(guo)排(pai)灰裝置(zhi)放(fang)出，回(hui)收有物料(liao)，被)凈化的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體(ti)排(pai)入(ru)大(da)氣(qi)(qi)(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)工作原(yuan)理(li)是利用(yong)高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)流(liu)中(zhong)的(de)(de)粉(fen)(fen)塵(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)場作用(yong)下與(yu)氣(qi)流(liu)分離(li)。負極(ji)(ji)(ji)由(you)不(bu)同(tong)斷面形(xing)(xing)狀的(de)(de)金(jin)屬(shu)導(dao)線(xian)制成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由(you)不(bu)同(tong)幾何形(xing)(xing)狀的(de)(de)金(jin)屬(shu)板制成(cheng)，叫(jiao)集塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)性能受粉(fen)(fen)塵(chen)性質(zhi)、設備構(gou)造和(he)(he)煙氣(qi)流(liu)速等三(san)個(ge)因素的(de)(de)影(ying)響。粉(fen)(fen)塵(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是評價(jia)導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除塵(chen)效(xiao)率有直接的(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)粒難以保持(chi)在集塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，致使其重返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到達集塵(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易放(fang)出(chu)，在塵(chen)層之間(jian)形(xing)(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會產生局部(bu)擊穿(chuan)和(he)(he)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些(xie)情況都會造成(cheng)除塵(chen)效(xiao)率下降。

電除塵(chen)(chen)器的基本(ben)原理是利用電力捕(bu)(bu)集(ji)(ji)煙氣中(zhong)的粉塵(chen)(chen)，主(zhu)要包括以下四個相互有關的物理過(guo)程: (1) 氣體的電離。(2) 粉塵(chen)(chen)的荷(he)電。(3) 荷(he)電粉塵(chen)(chen)向電極(ji)移動。(4) 荷(he)電粉塵(chen)(chen)的捕(bu)(bu)集(ji)(ji)。
