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)(dian)除(chu)塵器(qi)是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化法來(lai)收捕廢氣(qi)(qi)中(zhong)的(de)(de)粉(fen)塵，它的(de)(de)凈(jing)(jing)化工(gong)作上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和沉淀兩個系統(tong)來(lai)完成的(de)(de)，當含塵氣(qi)(qi)體(ti)(ti)(ti)進人(ren)氣(qi)(qi)刺叭(ba)時，含塵氣(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)流(liu)分布板(ban)以及(ji)折(zhe)流(liu)板(ban)的(de)(de)調整后，使(shi)氣(qi)(qi)流(liu)能較均勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)橫(heng)斷面擴(kuo)大(da)的(de)(de)作用下，氣(qi)(qi)流(liu)速度迅速降(jiang)低，其中(zhong)有些(xie)(xie)較重的(de)(de)塵粒便失(shi)去(qu)速度而沉降(jiang)下來(lai)。進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)含塵氣(qi)(qi)體(ti)(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通(tong)人(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象(xiang)，使(shi)氣(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)體(ti)(ti)(ti)中(zhong)存在(zai)大(da)量(liang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些(xie)(xie)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉(fen)塵結合(he)起來(lai)，使(shi)塵粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵粒在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作用下趨(qu)向本設(she)備(bei)陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設(she)備(bei)采用負高壓制)和陰(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋(shi)放(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別沉積(ji)(ji)在(zai)相應(ying)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通(tong)過(guo)設(she)備(bei)陰(yin)陽極(ji)(ji)(ji)振打系統(tong)的(de)(de)振打，使(shi)沉積(ji)(ji)在(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)粉(fen)塵振落，進人(ren)集灰斗 通(tong)過(guo)排(pai)灰裝置放(fang)出(chu)，回收有物料，被)凈(jing)(jing)化的(de)(de)氣(qi)(qi)體(ti)(ti)(ti)排(pai)入(ru)大(da)氣(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器的工作原理(li)是利用高(gao)壓(ya)電(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)離，氣(qi)流(liu)(liu)中的粉塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用下與氣(qi)流(liu)(liu)分離。負極(ji)由不同斷面形狀(zhuang)的金(jin)屬導線(xian)制(zhi)成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不同幾何形狀(zhuang)的金(jin)屬板制(zhi)成，叫集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器的性能受粉塵(chen)(chen)(chen)(chen)(chen)性質、設(she)備構造和煙氣(qi)流(liu)(liu)速(su)等三個因(yin)素的影(ying)響。粉塵(chen)(chen)(chen)(chen)(chen)的比電(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)性的指標，它(ta)對除(chu)塵(chen)(chen)(chen)(chen)(chen)效(xiao)率有直接的影(ying)響。比電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)(chen)粒難以保(bao)持在集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其重(zhong)返氣(qi)流(liu)(liu)。比電(dian)(dian)(dian)阻過高(gao)，到達集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)(chen)(chen)(chen)層(ceng)之間形成電(dian)(dian)(dian)壓(ya)梯(ti)度會(hui)(hui)產生局(ju)部擊(ji)穿和放電(dian)(dian)(dian)現象。這些(xie)情況都會(hui)(hui)造成除(chu)塵(chen)(chen)(chen)(chen)(chen)效(xiao)率下降(jiang)。

電(dian)除塵器(qi)的(de)(de)基本原理(li)(li)是(shi)利用(yong)電(dian)力捕集煙氣中的(de)(de)粉塵，主要(yao)包括以下四個相(xiang)互有關的(de)(de)物理(li)(li)過程: (1) 氣體的(de)(de)電(dian)離。(2) 粉塵的(de)(de)荷電(dian)。(3) 荷電(dian)粉塵向電(dian)極移動。(4) 荷電(dian)粉塵的(de)(de)捕集。
