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(shi)靜(jing)電(dian)除塵(chen)(chen)(chen)器是(shi)以(yi)靜(jing)電(dian)凈化(hua)法來收捕廢氣(qi)(qi)中(zhong)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它(ta)的(de)(de)(de)凈化(hua)工作上(shang)(shang)要是(shi)依靠電(dian)暈(yun)極(ji)和(he)(he)(he)沉淀兩個系統來完成的(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流分布(bu)板以(yi)及折流板的(de)(de)(de)調整后，使(shi)氣(qi)(qi)流能較均勻地進(jin)人(ren)電(dian)場。在橫斷面擴大的(de)(de)(de)作用(yong)下(xia)(xia)(xia)，氣(qi)(qi)流速度(du)迅速降(jiang)(jiang)低，其中(zhong)有些較重的(de)(de)(de)塵(chen)(chen)(chen)粒便(bian)失(shi)去速度(du)而沉降(jiang)(jiang)下(xia)(xia)(xia)來。進(jin)人(ren)電(dian)場的(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)暈(yun)極(ji)通(tong)人(ren)高壓直流電(dian)，則在電(dian)暈(yun)極(ji)附近產生電(dian)暈(yun)現(xian)象(xiang)，使(shi)氣(qi)(qi)體(ti)電(dian)離，電(dian)離后的(de)(de)(de)氣(qi)(qi)體(ti)中(zhong)存在大量的(de)(de)(de)電(dian)子和(he)(he)(he)離子，這(zhe)些電(dian)子和(he)(he)(he)離子與進(jin)人(ren)電(dian)場的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結合(he)起(qi)來，使(shi)塵(chen)(chen)(chen)粒帶電(dian)，帶電(dian)塵(chen)(chen)(chen)粒在電(dian)場力的(de)(de)(de)作用(yong)下(xia)(xia)(xia)趨向本設備陽極(ji)(正極(ji)、本設備采(cai)用(yong)負(fu)高壓制)和(he)(he)(he)陰(yin)(yin)極(ji)(負(fu)極(ji)) ， 釋放出(chu)電(dian)子分別沉積(ji)在相(xiang)應的(de)(de)(de)電(dian)極(ji)上(shang)(shang)，通(tong)過設備陰(yin)(yin)陽極(ji)振(zhen)打系統的(de)(de)(de)振(zhen)打，使(shi)沉積(ji)在陰(yin)(yin)陽電(dian)極(ji)上(shang)(shang)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)落，進(jin)人(ren)集灰斗 通(tong)過排灰裝置放出(chu)，回(hui)收有物料，被)凈化(hua)的(de)(de)(de)氣(qi)(qi)體(ti)排入大氣(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵器(qi)的(de)(de)工作原理是利(li)用高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)場使煙氣(qi)發(fa)生電(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)(de)粉(fen)塵荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場作用下與氣(qi)流(liu)分離。負(fu)極(ji)由不(bu)同(tong)斷(duan)面形狀的(de)(de)金屬導(dao)線制(zhi)成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同(tong)幾何形狀的(de)(de)金屬板制(zhi)成(cheng)，叫集(ji)塵電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵器(qi)的(de)(de)性(xing)能(neng)受粉(fen)塵性(xing)質、設備構造和煙氣(qi)流(liu)速等三(san)個因素(su)的(de)(de)影(ying)響。粉(fen)塵的(de)(de)比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是評(ping)價(jia)導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除塵效(xiao)率有直接的(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)(guo)低(di)，塵粒(li)難以保持在(zai)集(ji)塵電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，致使其重返氣(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)(guo)高，到達(da)集(ji)塵電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵粒(li)電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易(yi)放(fang)出，在(zai)塵層(ceng)之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會產(chan)生局部擊穿(chuan)和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情(qing)況(kuang)都會造成(cheng)除塵效(xiao)率下降。

電(dian)除(chu)塵(chen)器的(de)(de)基本(ben)原理是利用電(dian)力捕集煙(yan)氣中(zhong)的(de)(de)粉(fen)(fen)(fen)塵(chen)，主(zhu)要包括以下四個(ge)相互(hu)有關的(de)(de)物理過程: (1) 氣體的(de)(de)電(dian)離。(2) 粉(fen)(fen)(fen)塵(chen)的(de)(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)(fen)(fen)塵(chen)向電(dian)極(ji)移動。(4) 荷(he)電(dian)粉(fen)(fen)(fen)塵(chen)的(de)(de)捕集。
