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(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)法來(lai)收捕廢(fei)氣(qi)(qi)(qi)中的(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)凈化(hua)工作上要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)和(he)沉(chen)淀(dian)兩個系(xi)(xi)統來(lai)完成的(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)(liu)分布板以及折流(liu)(liu)板的(de)(de)調整后，使(shi)氣(qi)(qi)(qi)流(liu)(liu)能較均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大的(de)(de)作用(yong)下，氣(qi)(qi)(qi)流(liu)(liu)速(su)度(du)迅(xun)速(su)降低，其中有(you)些較重(zhong)的(de)(de)塵(chen)(chen)(chen)粒便失(shi)去速(su)度(du)而沉(chen)降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)通(tong)(tong)人(ren)高壓(ya)直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)附近(jin)產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現象，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)(qi)體(ti)中存在(zai)大量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子，這些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)(chen)結合(he)起來(lai)，使(shi)塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用(yong)下趨向本設備(bei)陽極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設備(bei)采用(yong)負高壓(ya)制(zhi))和(he)陰極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋(shi)放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積(ji)在(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，通(tong)(tong)過(guo)(guo)設備(bei)陰陽極(ji)(ji)(ji)(ji)振(zhen)打系(xi)(xi)統的(de)(de)振(zhen)打，使(shi)沉(chen)積(ji)在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上的(de)(de)粉塵(chen)(chen)(chen)振(zhen)落，進(jin)人(ren)集灰斗(dou) 通(tong)(tong)過(guo)(guo)排灰裝置放(fang)出，回收有(you)物(wu)料，被)凈化(hua)的(de)(de)氣(qi)(qi)(qi)體(ti)排入大氣(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器的(de)(de)工作(zuo)原(yuan)理是利用高(gao)壓電(dian)(dian)(dian)場使煙氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)(de)粉塵(chen)荷(he)電(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)場作(zuo)用下(xia)與氣(qi)(qi)流(liu)分離。負極由(you)不(bu)同(tong)斷(duan)面形(xing)狀的(de)(de)金(jin)屬(shu)導線制成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由(you)不(bu)同(tong)幾(ji)何形(xing)狀的(de)(de)金(jin)屬(shu)板制成(cheng)，叫(jiao)集塵(chen)電(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器的(de)(de)性(xing)(xing)能(neng)受粉塵(chen)性(xing)(xing)質、設(she)備(bei)構造和煙氣(qi)(qi)流(liu)速等三個因(yin)素(su)的(de)(de)影(ying)(ying)響(xiang)。粉塵(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻(zu)是評(ping)價導電(dian)(dian)(dian)性(xing)(xing)的(de)(de)指(zhi)標(biao)，它(ta)對除(chu)(chu)塵(chen)效率(lv)有直(zhi)接的(de)(de)影(ying)(ying)響(xiang)。比(bi)電(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)粒難以保持在(zai)(zai)集塵(chen)電(dian)(dian)(dian)極上(shang)，致(zhi)使其重返氣(qi)(qi)流(liu)。比(bi)電(dian)(dian)(dian)阻(zu)過(guo)高(gao)，到達集塵(chen)電(dian)(dian)(dian)極的(de)(de)塵(chen)粒電(dian)(dian)(dian)荷(he)不(bu)易放(fang)出，在(zai)(zai)塵(chen)層(ceng)之(zhi)間形(xing)成(cheng)電(dian)(dian)(dian)壓梯度(du)會產(chan)生(sheng)局部擊(ji)穿和放(fang)電(dian)(dian)(dian)現象。這些情況都(dou)會造成(cheng)除(chu)(chu)塵(chen)效率(lv)下(xia)降(jiang)。

電(dian)(dian)除塵器(qi)的(de)(de)基本原(yuan)理是利用電(dian)(dian)力捕(bu)(bu)集煙氣(qi)中的(de)(de)粉塵，主要包括以下四(si)個相互有關的(de)(de)物理過程: (1) 氣(qi)體(ti)的(de)(de)電(dian)(dian)離。(2) 粉塵的(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉塵的(de)(de)捕(bu)(bu)集。
