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)除塵器是以靜電(dian)(dian)(dian)(dian)凈(jing)化(hua)法來收捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)粉塵，它的(de)(de)(de)凈(jing)化(hua)工(gong)作上(shang)要是依(yi)靠電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)(ji)(ji)(ji)和沉(chen)淀兩(liang)個(ge)系(xi)統(tong)來完成的(de)(de)(de)，當(dang)含塵氣(qi)(qi)(qi)(qi)體(ti)(ti)進(jin)(jin)人(ren)氣(qi)(qi)(qi)(qi)刺(ci)叭時，含塵氣(qi)(qi)(qi)(qi)體(ti)(ti)受到(dao)氣(qi)(qi)(qi)(qi)流(liu)分布板以及折流(liu)板的(de)(de)(de)調整(zheng)后，使氣(qi)(qi)(qi)(qi)流(liu)能較(jiao)均勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場。在(zai)橫斷面擴大(da)(da)的(de)(de)(de)作用(yong)(yong)下(xia)，氣(qi)(qi)(qi)(qi)流(liu)速(su)度(du)迅(xun)速(su)降(jiang)低，其中(zhong)有些較(jiao)重(zhong)的(de)(de)(de)塵粒(li)便失(shi)去速(su)度(du)而(er)沉(chen)降(jiang)下(xia)來。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵氣(qi)(qi)(qi)(qi)體(ti)(ti)由(you)于電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)(ji)(ji)(ji)通(tong)(tong)人(ren)高(gao)壓直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)(ji)(ji)(ji)附(fu)近產生(sheng)電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)現象，使氣(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)存在(zai)大(da)(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子和離子，這些電(dian)(dian)(dian)(dian)子和離子與進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵結合起來，使塵粒(li)帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵粒(li)在(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用(yong)(yong)下(xia)趨(qu)向本(ben)設備(bei)陽極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本(ben)設備(bei)采用(yong)(yong)負高(gao)壓制)和陰(yin)極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分別沉(chen)積(ji)在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)，通(tong)(tong)過(guo)設備(bei)陰(yin)陽極(ji)(ji)(ji)(ji)振(zhen)打系(xi)統(tong)的(de)(de)(de)振(zhen)打，使沉(chen)積(ji)在(zai)陰(yin)陽電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)的(de)(de)(de)粉塵振(zhen)落，進(jin)(jin)人(ren)集灰(hui)斗(dou) 通(tong)(tong)過(guo)排灰(hui)裝置放出，回收有物料，被(bei))凈(jing)化(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)排入大(da)(da)氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)工(gong)作原理是(shi)利用高壓電(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)發(fa)生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場作用下(xia)與氣(qi)流(liu)分離。負(fu)極由不同斷面形狀的(de)金(jin)屬導線制成(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由不同幾(ji)何形狀的(de)金(jin)屬板制成(cheng)，叫(jiao)集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)性(xing)能(neng)受粉塵(chen)(chen)(chen)性(xing)質、設備構造和(he)煙(yan)氣(qi)流(liu)速等(deng)三個(ge)因素的(de)影(ying)響(xiang)。粉塵(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)指標，它對除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率(lv)有直(zhi)接的(de)影(ying)響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒難以保持在(zai)集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使其重返(fan)氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到達集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易放出(chu)，在(zai)塵(chen)(chen)(chen)層之(zhi)間形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿和(he)放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成(cheng)除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率(lv)下(xia)降。

電(dian)(dian)除(chu)塵(chen)器的基本原(yuan)理(li)(li)是利用電(dian)(dian)力捕集(ji)煙(yan)氣(qi)中的粉塵(chen)，主要包括以下四個(ge)相互有關的物理(li)(li)過程: (1) 氣(qi)體(ti)的電(dian)(dian)離(li)。(2) 粉塵(chen)的荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵(chen)向電(dian)(dian)極移動(dong)。(4) 荷(he)電(dian)(dian)粉塵(chen)的捕集(ji)。
