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(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器是以(yi)(yi)靜(jing)電(dian)(dian)(dian)(dian)凈化(hua)(hua)法來(lai)收(shou)捕廢氣(qi)(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)(de)(de)粉塵(chen)，它的(de)(de)(de)(de)(de)(de)(de)凈化(hua)(hua)工作(zuo)(zuo)上要是依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)和(he)沉淀兩(liang)個系(xi)統來(lai)完成的(de)(de)(de)(de)(de)(de)(de)，當含(han)塵(chen)氣(qi)(qi)(qi)(qi)(qi)體進(jin)人(ren)(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)氣(qi)(qi)(qi)(qi)(qi)體受(shou)到氣(qi)(qi)(qi)(qi)(qi)流(liu)分布板(ban)以(yi)(yi)及(ji)折流(liu)板(ban)的(de)(de)(de)(de)(de)(de)(de)調整(zheng)后，使(shi)氣(qi)(qi)(qi)(qi)(qi)流(liu)能(neng)較(jiao)均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)(de)(de)(de)(de)(de)(de)作(zuo)(zuo)用(yong)下，氣(qi)(qi)(qi)(qi)(qi)流(liu)速度迅速降低，其中(zhong)有些較(jiao)重的(de)(de)(de)(de)(de)(de)(de)塵(chen)粒便失去速度而沉降下來(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)(de)含(han)塵(chen)氣(qi)(qi)(qi)(qi)(qi)體由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)通人(ren)(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產(chan)生電(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體中(zhong)存在(zai)大(da)量(liang)的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)子(zi)(zi)與(yu)進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)(de)(de)粉塵(chen)結(jie)合起來(lai)，使(shi)塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)粒在(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)(de)(de)作(zuo)(zuo)用(yong)下趨向(xiang)本(ben)設備陽(yang)極(ji)(正極(ji)、本(ben)設備采用(yong)負(fu)(fu)高壓制)和(he)陰極(ji)(負(fu)(fu)極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)(zi)分別沉積(ji)在(zai)相應(ying)的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)上，通過(guo)設備陰陽(yang)極(ji)振(zhen)(zhen)打(da)系(xi)統的(de)(de)(de)(de)(de)(de)(de)振(zhen)(zhen)打(da)，使(shi)沉積(ji)在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)(de)(de)(de)粉塵(chen)振(zhen)(zhen)落，進(jin)人(ren)(ren)集灰(hui)斗(dou) 通過(guo)排(pai)灰(hui)裝置放出，回收(shou)有物料(liao)，被)凈化(hua)(hua)的(de)(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體排(pai)入大(da)氣(qi)(qi)(qi)(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵器(qi)的(de)工作(zuo)原理是利用(yong)高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)使(shi)煙氣發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)粉(fen)塵荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用(yong)下與氣流(liu)分離。負(fu)極由不(bu)同斷面形狀的(de)金屬導(dao)線制(zhi)成(cheng)(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極。正極由不(bu)同幾何形狀的(de)金屬板制(zhi)成(cheng)(cheng)，叫集(ji)塵電(dian)(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵器(qi)的(de)性(xing)能受粉(fen)塵性(xing)質、設備構(gou)造和煙氣流(liu)速等三個因素的(de)影(ying)響。粉(fen)塵的(de)比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)是評價導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)指標，它對除(chu)塵效(xiao)率有直接的(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過(guo)低，塵粒(li)難以保持在集(ji)塵電(dian)(dian)(dian)(dian)(dian)(dian)極上，致使(shi)其重返氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過(guo)高，到達集(ji)塵電(dian)(dian)(dian)(dian)(dian)(dian)極的(de)塵粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易放出，在塵層之間(jian)形成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會(hui)產生(sheng)局部擊穿和放電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情(qing)況都會(hui)造成(cheng)(cheng)除(chu)塵效(xiao)率下降。

電(dian)除塵器的(de)(de)基本原理(li)是(shi)利用電(dian)力捕(bu)集煙氣中的(de)(de)粉(fen)塵，主要包括以下四(si)個(ge)相互有(you)關的(de)(de)物理(li)過程(cheng): (1) 氣體(ti)(ti)的(de)(de)電(dian)離。(2) 粉(fen)塵的(de)(de)荷(he)(he)(he)電(dian)。(3) 荷(he)(he)(he)電(dian)粉(fen)塵向電(dian)極移動。(4) 荷(he)(he)(he)電(dian)粉(fen)塵的(de)(de)捕(bu)集。
