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)除塵(chen)(chen)(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收(shou)(shou)捕廢(fei)氣(qi)(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)(de)凈(jing)化(hua)工作上要是依(yi)靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)(he)沉(chen)淀兩個系(xi)統來(lai)完成(cheng)的(de)(de)(de)(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)進人(ren)(ren)(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)分(fen)布板以及折流(liu)(liu)板的(de)(de)(de)(de)(de)(de)調(diao)整(zheng)后，使氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)能較均勻地(di)進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫斷(duan)面(mian)擴大(da)的(de)(de)(de)(de)(de)(de)作用(yong)下(xia)，氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)速度(du)迅速降低，其(qi)中(zhong)有些較重的(de)(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)(li)便失(shi)去(qu)速度(du)而沉(chen)降下(xia)來(lai)。進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通(tong)(tong)人(ren)(ren)(ren)高壓(ya)直流(liu)(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)中(zhong)存在(zai)(zai)大(da)量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)(he)離(li)子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)子(zi)和(he)(he)離(li)子(zi)與進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結合起來(lai)，使塵(chen)(chen)(chen)粒(li)(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)(de)(de)作用(yong)下(xia)趨向本設備陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備采用(yong)負高壓(ya)制)和(he)(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)積在(zai)(zai)相(xiang)應的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通(tong)(tong)過設備陰陽(yang)極(ji)(ji)(ji)振打系(xi)統的(de)(de)(de)(de)(de)(de)振打，使沉(chen)積在(zai)(zai)陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振落(luo)，進人(ren)(ren)(ren)集灰斗 通(tong)(tong)過排灰裝置放出，回收(shou)(shou)有物料，被)凈(jing)化(hua)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)排入大(da)氣(qi)(qi)(qi)(qi)(qi)。

工作(zuo)原理

靜電(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)工作(zuo)原理是利(li)用(yong)高壓(ya)電(dian)場使(shi)煙氣發生電(dian)離，氣流(liu)中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)荷電(dian)在(zai)電(dian)場作(zuo)用(yong)下(xia)與氣流(liu)分離。負極(ji)由不同(tong)斷(duan)面形(xing)狀(zhuang)的(de)金屬導線制成(cheng)(cheng)，叫放電(dian)電(dian)極(ji)。正極(ji)由不同(tong)幾何形(xing)狀(zhuang)的(de)金屬板制成(cheng)(cheng)，叫集塵(chen)(chen)(chen)(chen)(chen)電(dian)極(ji)。靜電(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)(chen)性(xing)質、設備(bei)構造和煙氣流(liu)速等三個因素的(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)(chen)的(de)比(bi)電(dian)阻(zu)(zu)是評(ping)價導電(dian)性(xing)的(de)指標，它對(dui)除(chu)塵(chen)(chen)(chen)(chen)(chen)效(xiao)率有直接(jie)的(de)影響(xiang)。比(bi)電(dian)阻(zu)(zu)過低，塵(chen)(chen)(chen)(chen)(chen)粒難(nan)以保持(chi)在(zai)集塵(chen)(chen)(chen)(chen)(chen)電(dian)極(ji)上(shang)，致(zhi)使(shi)其重返氣流(liu)。比(bi)電(dian)阻(zu)(zu)過高，到達集塵(chen)(chen)(chen)(chen)(chen)電(dian)極(ji)的(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)荷不易放出(chu)，在(zai)塵(chen)(chen)(chen)(chen)(chen)層之間形(xing)成(cheng)(cheng)電(dian)壓(ya)梯度會產生局部(bu)擊穿和放電(dian)現象(xiang)。這(zhe)些情況都會造成(cheng)(cheng)除(chu)塵(chen)(chen)(chen)(chen)(chen)效(xiao)率下(xia)降。

電除塵器的基本原理是利(li)用電力捕集(ji)煙氣中的粉(fen)塵，主要包(bao)括以(yi)下四個相互有(you)關的物理過(guo)程: (1) 氣體(ti)的電離。(2) 粉(fen)塵的荷電。(3) 荷電粉(fen)塵向電極移動。(4) 荷電粉(fen)塵的捕集(ji)。
