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)靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法來(lai)收(shou)捕(bu)廢氣(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)凈(jing)(jing)化(hua)工作(zuo)上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)和(he)沉(chen)淀(dian)兩個系統來(lai)完成(cheng)的(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)(qi)體進(jin)(jin)人(ren)氣(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)分布(bu)板以及折流(liu)板的(de)(de)(de)調整后，使(shi)氣(qi)(qi)流(liu)能(neng)較均勻地(di)進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面擴大(da)的(de)(de)(de)作(zuo)用(yong)下(xia)(xia)，氣(qi)(qi)流(liu)速度迅速降(jiang)(jiang)低，其中有些較重的(de)(de)(de)塵(chen)(chen)(chen)粒(li)便失去(qu)速度而(er)沉(chen)降(jiang)(jiang)下(xia)(xia)來(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通人(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)氣(qi)(qi)體中存在(zai)大(da)量(liang)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子，這些電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子與進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)作(zuo)用(yong)下(xia)(xia)趨向本(ben)設備陽(yang)極(ji)(正極(ji)、本(ben)設備采(cai)用(yong)負高壓制(zhi))和(he)陰極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子分別(bie)沉(chen)積在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通過設備陰陽(yang)極(ji)振打系統的(de)(de)(de)振打，使(shi)沉(chen)積在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)粉塵(chen)(chen)(chen)振落，進(jin)(jin)人(ren)集灰(hui)斗 通過排(pai)灰(hui)裝置放出，回(hui)收(shou)有物料，被)凈(jing)(jing)化(hua)的(de)(de)(de)氣(qi)(qi)體排(pai)入大(da)氣(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)除塵(chen)(chen)器的(de)工作原理是(shi)利用(yong)(yong)高(gao)壓(ya)(ya)電(dian)(dian)場使(shi)煙(yan)氣(qi)(qi)發生電(dian)(dian)離，氣(qi)(qi)流(liu)(liu)中的(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場作用(yong)(yong)下與氣(qi)(qi)流(liu)(liu)分離。負極(ji)(ji)由不(bu)同(tong)斷面(mian)形(xing)狀的(de)金(jin)屬(shu)導(dao)線制成(cheng)，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同(tong)幾(ji)何形(xing)狀的(de)金(jin)屬(shu)板制成(cheng)，叫(jiao)集(ji)(ji)塵(chen)(chen)電(dian)(dian)極(ji)(ji)。靜電(dian)(dian)除塵(chen)(chen)器的(de)性能受粉(fen)塵(chen)(chen)性質(zhi)、設備構造和(he)煙(yan)氣(qi)(qi)流(liu)(liu)速(su)等三個因素的(de)影(ying)響(xiang)。粉(fen)塵(chen)(chen)的(de)比電(dian)(dian)阻(zu)是(shi)評(ping)價導(dao)電(dian)(dian)性的(de)指標，它對除塵(chen)(chen)效率有(you)直(zhi)接的(de)影(ying)響(xiang)。比電(dian)(dian)阻(zu)過低，塵(chen)(chen)粒難以(yi)保持在(zai)集(ji)(ji)塵(chen)(chen)電(dian)(dian)極(ji)(ji)上，致(zhi)使(shi)其重(zhong)返(fan)氣(qi)(qi)流(liu)(liu)。比電(dian)(dian)阻(zu)過高(gao)，到(dao)達集(ji)(ji)塵(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)粒電(dian)(dian)荷不(bu)易放出，在(zai)塵(chen)(chen)層之(zhi)間形(xing)成(cheng)電(dian)(dian)壓(ya)(ya)梯度會(hui)產生局部擊(ji)穿和(he)放電(dian)(dian)現象。這些情況都會(hui)造成(cheng)除塵(chen)(chen)效率下降。

電(dian)除塵器的(de)(de)基(ji)本(ben)原理是利(li)用電(dian)力捕集煙(yan)氣中的(de)(de)粉(fen)塵，主(zhu)要包括以(yi)下四個相互有關的(de)(de)物理過程: (1) 氣體(ti)的(de)(de)電(dian)離。(2) 粉(fen)塵的(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵向電(dian)極移動。(4) 荷電(dian)粉(fen)塵的(de)(de)捕集。
