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(wo)式(shi)靜電(dian)(dian)(dian)除塵器是以靜電(dian)(dian)(dian)凈(jing)(jing)化(hua)(hua)法來(lai)收捕廢氣(qi)中(zhong)(zhong)的(de)(de)粉(fen)塵，它的(de)(de)凈(jing)(jing)化(hua)(hua)工作上要(yao)是依靠電(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)沉淀兩個系統(tong)來(lai)完(wan)成(cheng)的(de)(de)，當含塵氣(qi)體(ti)(ti)(ti)進(jin)人(ren)(ren)(ren)(ren)氣(qi)刺叭時，含塵氣(qi)體(ti)(ti)(ti)受到氣(qi)流分(fen)布板以及折流板的(de)(de)調整后，使氣(qi)流能較均勻地進(jin)人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場。在(zai)橫斷面擴大(da)(da)的(de)(de)作用(yong)下(xia)，氣(qi)流速度(du)(du)迅速降低，其中(zhong)(zhong)有些較重的(de)(de)塵粒便失去(qu)速度(du)(du)而沉降下(xia)來(lai)。進(jin)人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場的(de)(de)含塵氣(qi)體(ti)(ti)(ti)由于(yu)電(dian)(dian)(dian)暈極(ji)(ji)(ji)通(tong)人(ren)(ren)(ren)(ren)高壓直(zhi)流電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)暈現象，使氣(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)體(ti)(ti)(ti)中(zhong)(zhong)存在(zai)大(da)(da)量的(de)(de)電(dian)(dian)(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)，這(zhe)些電(dian)(dian)(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)與進(jin)人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場的(de)(de)粉(fen)塵結合(he)起來(lai)，使塵粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵粒在(zai)電(dian)(dian)(dian)場力(li)的(de)(de)作用(yong)下(xia)趨(qu)向(xiang)本(ben)設備(bei)陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設備(bei)采用(yong)負高壓制)和(he)陰(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子(zi)(zi)分(fen)別沉積(ji)在(zai)相應(ying)的(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)上，通(tong)過(guo)設備(bei)陰(yin)陽極(ji)(ji)(ji)振(zhen)打系統(tong)的(de)(de)振(zhen)打，使沉積(ji)在(zai)陰(yin)陽電(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)粉(fen)塵振(zhen)落，進(jin)人(ren)(ren)(ren)(ren)集灰斗 通(tong)過(guo)排(pai)灰裝置(zhi)放出(chu)，回收有物料，被)凈(jing)(jing)化(hua)(hua)的(de)(de)氣(qi)體(ti)(ti)(ti)排(pai)入(ru)大(da)(da)氣(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)工作原理是利用(yong)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)(de)粉(fen)(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)場作用(yong)下(xia)與氣(qi)(qi)流(liu)分離。負極(ji)由(you)不同(tong)斷面形狀的(de)(de)(de)金屬(shu)導(dao)線制(zhi)成，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同(tong)幾何形狀的(de)(de)(de)金屬(shu)板制(zhi)成，叫(jiao)集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)性能受粉(fen)(fen)塵(chen)(chen)性質、設備(bei)構造(zao)和煙氣(qi)(qi)流(liu)速(su)等三個因素的(de)(de)(de)影響。粉(fen)(fen)塵(chen)(chen)的(de)(de)(de)比(bi)(bi)電(dian)(dian)(dian)阻(zu)是評(ping)價導(dao)電(dian)(dian)(dian)性的(de)(de)(de)指標，它對(dui)除(chu)(chu)(chu)塵(chen)(chen)效(xiao)率有直接的(de)(de)(de)影響。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)低(di)，塵(chen)(chen)粒(li)難以保持在(zai)(zai)集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)(qi)流(liu)。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)高(gao)，到(dao)達集(ji)塵(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)荷(he)不易放出，在(zai)(zai)塵(chen)(chen)層(ceng)之間形成電(dian)(dian)(dian)壓梯(ti)度會產生(sheng)局部擊穿和放電(dian)(dian)(dian)現象。這些情況都會造(zao)成除(chu)(chu)(chu)塵(chen)(chen)效(xiao)率下(xia)降(jiang)。

電(dian)(dian)除塵(chen)器的(de)基本原理是利用(yong)電(dian)(dian)力捕(bu)集(ji)煙氣中的(de)粉塵(chen)，主要包括(kuo)以(yi)下四個(ge)相互有關(guan)的(de)物理過程: (1) 氣體(ti)的(de)電(dian)(dian)離。(2) 粉塵(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵(chen)向電(dian)(dian)極(ji)移動。(4) 荷電(dian)(dian)粉塵(chen)的(de)捕(bu)集(ji)。
