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)(dian)除塵(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)(lai)收捕(bu)廢氣(qi)(qi)(qi)中的(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)凈(jing)化(hua)工作(zuo)上(shang)要(yao)是依靠(kao)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)(he)沉(chen)淀兩個系統(tong)來(lai)(lai)完成的(de)(de)(de)，當含塵(chen)氣(qi)(qi)(qi)體(ti)(ti)進人氣(qi)(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流(liu)(liu)分(fen)布(bu)板(ban)以及折流(liu)(liu)板(ban)的(de)(de)(de)調(diao)整后，使(shi)氣(qi)(qi)(qi)流(liu)(liu)能較均勻地(di)進人電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷面擴大的(de)(de)(de)作(zuo)用下(xia)，氣(qi)(qi)(qi)流(liu)(liu)速度迅速降低，其中有些(xie)較重的(de)(de)(de)塵(chen)粒(li)便失去速度而沉(chen)降下(xia)來(lai)(lai)。進人電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通(tong)人高(gao)壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中存在(zai)(zai)大量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和(he)(he)離子，這些(xie)電(dian)(dian)(dian)(dian)(dian)子和(he)(he)離子與進人電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)結(jie)合起來(lai)(lai)，使(shi)塵(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)作(zuo)用下(xia)趨向本(ben)設備(bei)陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設備(bei)采用負高(gao)壓制)和(he)(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)(dian)子分(fen)別沉(chen)積(ji)在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通(tong)過設備(bei)陰陽極(ji)(ji)(ji)振(zhen)打系統(tong)的(de)(de)(de)振(zhen)打，使(shi)沉(chen)積(ji)在(zai)(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)粉(fen)塵(chen)振(zhen)落(luo)，進人集灰斗(dou) 通(tong)過排(pai)灰裝置放出，回收有物料，被)凈(jing)化(hua)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排(pai)入大氣(qi)(qi)(qi)。

工作原理(li)

靜(jing)電(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)工(gong)作(zuo)原(yuan)理是利用高(gao)壓電(dian)(dian)場使煙氣(qi)發(fa)生(sheng)電(dian)(dian)離(li)，氣(qi)流(liu)中的(de)(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)在(zai)(zai)電(dian)(dian)場作(zuo)用下與氣(qi)流(liu)分(fen)離(li)。負極(ji)由不(bu)(bu)同斷面形狀的(de)(de)(de)金屬(shu)導(dao)線制成，叫(jiao)放(fang)電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不(bu)(bu)同幾何形狀的(de)(de)(de)金屬(shu)板制成，叫(jiao)集塵(chen)(chen)電(dian)(dian)極(ji)。靜(jing)電(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)性(xing)(xing)能受粉(fen)塵(chen)(chen)性(xing)(xing)質、設(she)備構造(zao)和煙氣(qi)流(liu)速等(deng)三個因素的(de)(de)(de)影響(xiang)。粉(fen)塵(chen)(chen)的(de)(de)(de)比電(dian)(dian)阻(zu)是評價(jia)導(dao)電(dian)(dian)性(xing)(xing)的(de)(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)效率有直接的(de)(de)(de)影響(xiang)。比電(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)粒(li)難以保持在(zai)(zai)集塵(chen)(chen)電(dian)(dian)極(ji)上，致(zhi)使其重返氣(qi)流(liu)。比電(dian)(dian)阻(zu)過(guo)高(gao)，到(dao)達集塵(chen)(chen)電(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)荷不(bu)(bu)易放(fang)出，在(zai)(zai)塵(chen)(chen)層之間形成電(dian)(dian)壓梯度(du)會產生(sheng)局部擊穿和放(fang)電(dian)(dian)現象。這些(xie)情(qing)況都會造(zao)成除(chu)(chu)塵(chen)(chen)效率下降。

電(dian)(dian)(dian)除(chu)塵(chen)器的(de)基本原(yuan)理是利用電(dian)(dian)(dian)力捕集煙氣中的(de)粉塵(chen)，主要(yao)包括以下四個相互有關的(de)物理過程: (1) 氣體的(de)電(dian)(dian)(dian)離。(2) 粉塵(chen)的(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉塵(chen)向電(dian)(dian)(dian)極(ji)移動。(4) 荷電(dian)(dian)(dian)粉塵(chen)的(de)捕集。
