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)除(chu)塵(chen)(chen)(chen)器(qi)是(shi)以靜電(dian)(dian)凈化法來(lai)(lai)收捕廢氣(qi)中的(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)凈化工作上(shang)(shang)(shang)要是(shi)依靠電(dian)(dian)暈極(ji)和(he)沉(chen)淀(dian)兩(liang)個系(xi)統來(lai)(lai)完成的(de)(de)，當(dang)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)進(jin)人(ren)氣(qi)刺(ci)叭時，含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)受(shou)到(dao)氣(qi)流(liu)分(fen)布板以及折(zhe)流(liu)板的(de)(de)調整(zheng)后，使氣(qi)流(liu)能(neng)較均勻地進(jin)人(ren)電(dian)(dian)場。在橫斷面(mian)擴大的(de)(de)作用(yong)下(xia)，氣(qi)流(liu)速(su)度迅(xun)速(su)降(jiang)低，其中有些(xie)較重的(de)(de)塵(chen)(chen)(chen)粒便失(shi)去速(su)度而沉(chen)降(jiang)下(xia)來(lai)(lai)。進(jin)人(ren)電(dian)(dian)場的(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)由于電(dian)(dian)暈極(ji)通人(ren)高(gao)壓直流(liu)電(dian)(dian)，則在電(dian)(dian)暈極(ji)附近產生電(dian)(dian)暈現象(xiang)，使氣(qi)體(ti)(ti)(ti)電(dian)(dian)離(li)(li)，電(dian)(dian)離(li)(li)后的(de)(de)氣(qi)體(ti)(ti)(ti)中存在大量的(de)(de)電(dian)(dian)子(zi)(zi)(zi)和(he)離(li)(li)子(zi)(zi)(zi)，這些(xie)電(dian)(dian)子(zi)(zi)(zi)和(he)離(li)(li)子(zi)(zi)(zi)與進(jin)人(ren)電(dian)(dian)場的(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)(lai)，使塵(chen)(chen)(chen)粒帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵(chen)(chen)(chen)粒在電(dian)(dian)場力的(de)(de)作用(yong)下(xia)趨向(xiang)本設(she)備陽極(ji)(正極(ji)、本設(she)備采用(yong)負(fu)高(gao)壓制)和(he)陰極(ji)(負(fu)極(ji)) ， 釋放出電(dian)(dian)子(zi)(zi)(zi)分(fen)別(bie)沉(chen)積(ji)在相應的(de)(de)電(dian)(dian)極(ji)上(shang)(shang)(shang)，通過(guo)設(she)備陰陽極(ji)振(zhen)打系(xi)統的(de)(de)振(zhen)打，使沉(chen)積(ji)在陰陽電(dian)(dian)極(ji)上(shang)(shang)(shang)的(de)(de)粉塵(chen)(chen)(chen)振(zhen)落，進(jin)人(ren)集灰斗 通過(guo)排(pai)灰裝置放出，回收有物料，被(bei))凈化的(de)(de)氣(qi)體(ti)(ti)(ti)排(pai)入大氣(qi)。

工(gong)作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)工作(zuo)原理(li)是(shi)利用高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)中的(de)(de)粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下(xia)與氣(qi)流(liu)分離。負極由不(bu)(bu)同(tong)斷面(mian)形(xing)狀(zhuang)(zhuang)的(de)(de)金屬導線制成，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由不(bu)(bu)同(tong)幾何形(xing)狀(zhuang)(zhuang)的(de)(de)金屬板制成，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)性能受粉塵(chen)(chen)性質、設備構造(zao)和煙(yan)氣(qi)流(liu)速等三個(ge)因素(su)的(de)(de)影(ying)(ying)響(xiang)。粉塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評價(jia)導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它(ta)對(dui)除(chu)塵(chen)(chen)效(xiao)率有直接的(de)(de)影(ying)(ying)響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上(shang)，致(zhi)使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)(bu)易(yi)放出，在塵(chen)(chen)層(ceng)之(zhi)間形(xing)成電(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會產生局部擊(ji)穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情(qing)況都會造(zao)成除(chu)塵(chen)(chen)效(xiao)率下(xia)降(jiang)。

電除塵器(qi)的(de)(de)(de)基本(ben)原(yuan)理是利(li)用電力(li)捕集煙氣中的(de)(de)(de)粉塵，主要(yao)包括(kuo)以下四個相互有關的(de)(de)(de)物理過程: (1) 氣體的(de)(de)(de)電離。(2) 粉塵的(de)(de)(de)荷電。(3) 荷電粉塵向電極移(yi)動。(4) 荷電粉塵的(de)(de)(de)捕集。
