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)除塵(chen)(chen)(chen)器(qi)是(shi)以(yi)靜(jing)電(dian)(dian)(dian)(dian)凈(jing)化法來(lai)收捕(bu)廢氣(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)凈(jing)化工作上要是(shi)依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)和(he)(he)沉(chen)(chen)(chen)淀兩個系統來(lai)完(wan)成的(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進(jin)人(ren)氣(qi)(qi)刺叭(ba)時(shi)，含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受(shou)到氣(qi)(qi)流(liu)(liu)(liu)分布板以(yi)及折流(liu)(liu)(liu)板的(de)(de)(de)調整(zheng)后(hou)，使氣(qi)(qi)流(liu)(liu)(liu)能較均勻地(di)進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫斷(duan)面擴大(da)(da)的(de)(de)(de)作用(yong)下，氣(qi)(qi)流(liu)(liu)(liu)速度(du)迅速降低，其(qi)中有些較重(zhong)的(de)(de)(de)塵(chen)(chen)(chen)粒便失去速度(du)而(er)沉(chen)(chen)(chen)降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)暈(yun)極(ji)通人(ren)高(gao)壓直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)，則(ze)在(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產(chan)生電(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)氣(qi)(qi)體(ti)(ti)中存在(zai)(zai)大(da)(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子和(he)(he)離(li)子，這些電(dian)(dian)(dian)(dian)子和(he)(he)離(li)子與進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉塵(chen)(chen)(chen)結合起(qi)來(lai)，使塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)作用(yong)下趨向本設備(bei)陽極(ji)(正極(ji)、本設備(bei)采用(yong)負高(gao)壓制)和(he)(he)陰極(ji)(負極(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)子分別沉(chen)(chen)(chen)積在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)上，通過設備(bei)陰陽極(ji)振打(da)系統的(de)(de)(de)振打(da)，使沉(chen)(chen)(chen)積在(zai)(zai)陰陽電(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)粉塵(chen)(chen)(chen)振落，進(jin)人(ren)集灰斗 通過排灰裝置(zhi)放出(chu)，回收有物料，被)凈(jing)化的(de)(de)(de)氣(qi)(qi)體(ti)(ti)排入大(da)(da)氣(qi)(qi)。

工作(zuo)原理(li)

靜電(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)工作原理是(shi)利(li)用高壓電(dian)(dian)場(chang)使煙(yan)氣(qi)發生電(dian)(dian)離，氣(qi)流中的(de)(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場(chang)作用下與氣(qi)流分離。負(fu)極(ji)由不同(tong)斷面形狀的(de)(de)(de)金屬(shu)導(dao)線制成(cheng)，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)。正(zheng)極(ji)由不同(tong)幾何形狀的(de)(de)(de)金屬(shu)板(ban)制成(cheng)，叫(jiao)集(ji)(ji)(ji)塵(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)(de)性(xing)(xing)能受粉(fen)塵(chen)(chen)性(xing)(xing)質、設備構造和(he)煙(yan)氣(qi)流速等三個因素(su)的(de)(de)(de)影(ying)(ying)響。粉(fen)塵(chen)(chen)的(de)(de)(de)比電(dian)(dian)阻是(shi)評價(jia)導(dao)電(dian)(dian)性(xing)(xing)的(de)(de)(de)指標，它對除(chu)塵(chen)(chen)效(xiao)率有直接的(de)(de)(de)影(ying)(ying)響。比電(dian)(dian)阻過低，塵(chen)(chen)粒難以保持(chi)在集(ji)(ji)(ji)塵(chen)(chen)電(dian)(dian)極(ji)上(shang)，致使其重返氣(qi)流。比電(dian)(dian)阻過高，到(dao)達集(ji)(ji)(ji)塵(chen)(chen)電(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)荷不易(yi)放出，在塵(chen)(chen)層之間形成(cheng)電(dian)(dian)壓梯度會產生局部擊(ji)穿和(he)放電(dian)(dian)現象(xiang)。這些情況都(dou)會造成(cheng)除(chu)塵(chen)(chen)效(xiao)率下降。

電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)基本(ben)原理(li)是利(li)用電(dian)(dian)(dian)力捕集(ji)(ji)煙氣(qi)中的(de)(de)粉塵(chen)(chen)(chen)(chen)，主要包括以(yi)下四(si)個相(xiang)互(hu)有關的(de)(de)物理(li)過(guo)程(cheng): (1) 氣(qi)體的(de)(de)電(dian)(dian)(dian)離(li)。(2) 粉塵(chen)(chen)(chen)(chen)的(de)(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉塵(chen)(chen)(chen)(chen)向電(dian)(dian)(dian)極移(yi)動。(4) 荷電(dian)(dian)(dian)粉塵(chen)(chen)(chen)(chen)的(de)(de)捕集(ji)(ji)。
