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)除塵(chen)(chen)(chen)(chen)器是(shi)以(yi)靜電(dian)凈(jing)(jing)化法來(lai)(lai)收捕廢氣(qi)(qi)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，它(ta)的(de)(de)凈(jing)(jing)化工作(zuo)上要(yao)是(shi)依靠電(dian)暈(yun)極(ji)(ji)和(he)沉淀(dian)兩個(ge)系統(tong)來(lai)(lai)完成的(de)(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)進人(ren)(ren)(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)受到(dao)氣(qi)(qi)流(liu)(liu)分布(bu)板以(yi)及折流(liu)(liu)板的(de)(de)調整后，使氣(qi)(qi)流(liu)(liu)能較均勻(yun)地進人(ren)(ren)(ren)電(dian)場。在橫斷(duan)面擴大(da)的(de)(de)作(zuo)用(yong)(yong)下(xia)，氣(qi)(qi)流(liu)(liu)速(su)度(du)迅速(su)降(jiang)低，其(qi)中(zhong)有(you)些較重的(de)(de)塵(chen)(chen)(chen)(chen)粒便失去速(su)度(du)而沉降(jiang)下(xia)來(lai)(lai)。進人(ren)(ren)(ren)電(dian)場的(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)暈(yun)極(ji)(ji)通人(ren)(ren)(ren)高(gao)壓直流(liu)(liu)電(dian)，則(ze)在電(dian)暈(yun)極(ji)(ji)附(fu)近(jin)產(chan)生電(dian)暈(yun)現象(xiang)，使氣(qi)(qi)體(ti)電(dian)離(li)，電(dian)離(li)后的(de)(de)氣(qi)(qi)體(ti)中(zhong)存在大(da)量的(de)(de)電(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)，這(zhe)些電(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)與進人(ren)(ren)(ren)電(dian)場的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)結合起來(lai)(lai)，使塵(chen)(chen)(chen)(chen)粒帶電(dian)，帶電(dian)塵(chen)(chen)(chen)(chen)粒在電(dian)場力(li)的(de)(de)作(zuo)用(yong)(yong)下(xia)趨向本設(she)備陽(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)備采用(yong)(yong)負高(gao)壓制)和(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)子(zi)(zi)分別沉積(ji)在相應的(de)(de)電(dian)極(ji)(ji)上，通過設(she)備陰陽(yang)極(ji)(ji)振(zhen)打系統(tong)的(de)(de)振(zhen)打，使沉積(ji)在陰陽(yang)電(dian)極(ji)(ji)上的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)振(zhen)落，進人(ren)(ren)(ren)集灰斗 通過排灰裝置放出，回收有(you)物料，被)凈(jing)(jing)化的(de)(de)氣(qi)(qi)體(ti)排入(ru)大(da)氣(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)的(de)工作原理是利用高壓電(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)(qi)流中的(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作用下與氣(qi)(qi)流分離。負極(ji)(ji)由不(bu)同斷(duan)面形狀的(de)金屬(shu)導線(xian)制成，叫(jiao)放(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同幾(ji)何形狀的(de)金屬(shu)板制成，叫(jiao)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)的(de)性(xing)能受粉塵(chen)(chen)性(xing)質、設(she)備構造和煙氣(qi)(qi)流速等三個因素的(de)影(ying)響。粉塵(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)(dian)性(xing)的(de)指標，它對除(chu)塵(chen)(chen)效率有(you)直接的(de)影(ying)響。比(bi)電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒(li)難以保持在(zai)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其(qi)重返氣(qi)(qi)流。比(bi)電(dian)(dian)(dian)(dian)阻過高，到達(da)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不(bu)易(yi)放(fang)(fang)出，在(zai)塵(chen)(chen)層之間形成電(dian)(dian)(dian)(dian)壓梯(ti)度會(hui)(hui)產生局部擊穿(chuan)和放(fang)(fang)電(dian)(dian)(dian)(dian)現象。這些(xie)情況都會(hui)(hui)造成除(chu)塵(chen)(chen)效率下降。

電(dian)除塵(chen)(chen)器的(de)(de)基本原理是(shi)利用(yong)電(dian)力捕集煙(yan)氣中(zhong)的(de)(de)粉(fen)塵(chen)(chen)，主要包括以下四個相(xiang)互有(you)關的(de)(de)物理過程: (1) 氣體的(de)(de)電(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)(chen)向電(dian)極移(yi)動。(4) 荷電(dian)粉(fen)塵(chen)(chen)的(de)(de)捕集。
