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(shi)靜(jing)電(dian)(dian)(dian)除塵(chen)器是(shi)以(yi)靜(jing)電(dian)(dian)(dian)凈化(hua)法來收(shou)(shou)捕廢(fei)氣(qi)中的(de)(de)粉(fen)塵(chen)，它(ta)的(de)(de)凈化(hua)工作(zuo)(zuo)上(shang)要是(shi)依靠(kao)電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和(he)(he)(he)沉(chen)淀(dian)兩個(ge)系統來完成的(de)(de)，當含塵(chen)氣(qi)體(ti)(ti)進(jin)人(ren)(ren)氣(qi)刺叭時，含塵(chen)氣(qi)體(ti)(ti)受到氣(qi)流(liu)分(fen)布板(ban)以(yi)及折流(liu)板(ban)的(de)(de)調整后，使(shi)(shi)氣(qi)流(liu)能較均(jun)勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)。在橫斷(duan)面擴大(da)的(de)(de)作(zuo)(zuo)用(yong)下(xia)，氣(qi)流(liu)速(su)度迅速(su)降低，其中有些較重的(de)(de)塵(chen)粒(li)便(bian)失去速(su)度而沉(chen)降下(xia)來。進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)氣(qi)體(ti)(ti)由于電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通(tong)人(ren)(ren)高壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附(fu)近產生電(dian)(dian)(dian)暈(yun)(yun)現象，使(shi)(shi)氣(qi)體(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)氣(qi)體(ti)(ti)中存在大(da)量的(de)(de)電(dian)(dian)(dian)子(zi)和(he)(he)(he)離子(zi)，這些電(dian)(dian)(dian)子(zi)和(he)(he)(he)離子(zi)與(yu)進(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)結合(he)起來，使(shi)(shi)塵(chen)粒(li)帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)粒(li)在電(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)(zuo)用(yong)下(xia)趨向(xiang)本設備陽(yang)極(ji)(ji)(正極(ji)(ji)、本設備采用(yong)負高壓(ya)制)和(he)(he)(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子(zi)分(fen)別(bie)沉(chen)積在相應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過設備陰陽(yang)極(ji)(ji)振(zhen)打系統的(de)(de)振(zhen)打，使(shi)(shi)沉(chen)積在陰陽(yang)電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉(fen)塵(chen)振(zhen)落，進(jin)人(ren)(ren)集(ji)灰斗 通(tong)過排(pai)灰裝置放出(chu)，回收(shou)(shou)有物料(liao)，被)凈化(hua)的(de)(de)氣(qi)體(ti)(ti)排(pai)入大(da)氣(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)工作(zuo)原理(li)是(shi)利(li)用高(gao)(gao)壓電(dian)(dian)(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作(zuo)用下(xia)與氣(qi)流分離。負(fu)極(ji)由(you)不同(tong)斷面形(xing)(xing)狀(zhuang)的(de)(de)金屬(shu)導線制(zhi)(zhi)成(cheng)(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同(tong)幾何(he)形(xing)(xing)狀(zhuang)的(de)(de)金屬(shu)板制(zhi)(zhi)成(cheng)(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)性(xing)能受粉(fen)塵(chen)(chen)性(xing)質(zhi)、設備構造和煙氣(qi)流速等(deng)三個因素的(de)(de)影(ying)響(xiang)。粉(fen)塵(chen)(chen)的(de)(de)比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻是(shi)評價(jia)導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除(chu)塵(chen)(chen)效(xiao)(xiao)率有直接(jie)的(de)(de)影(ying)響(xiang)。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)粒(li)難以(yi)保持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)流。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)高(gao)(gao)，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷不易放出(chu)，在塵(chen)(chen)層之間形(xing)(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會(hui)產生局(ju)部(bu)擊(ji)穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些(xie)情(qing)況都會(hui)造成(cheng)(cheng)除(chu)塵(chen)(chen)效(xiao)(xiao)率下(xia)降。

電(dian)除塵(chen)(chen)器的基本原理(li)是利用(yong)電(dian)力(li)捕(bu)集煙氣中的粉(fen)塵(chen)(chen)，主要包括以下四個相互有關的物理(li)過程: (1) 氣體的電(dian)離。(2) 粉(fen)塵(chen)(chen)的荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵(chen)(chen)向電(dian)極移動。(4) 荷(he)電(dian)粉(fen)塵(chen)(chen)的捕(bu)集。
