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)除塵(chen)器是以靜電(dian)(dian)(dian)凈化(hua)法來收(shou)捕廢氣(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)，它(ta)的(de)(de)(de)(de)凈化(hua)工作(zuo)上(shang)要是依靠電(dian)(dian)(dian)暈極(ji)(ji)和沉淀兩個系統(tong)來完(wan)成(cheng)的(de)(de)(de)(de)，當含塵(chen)氣(qi)體(ti)進(jin)人(ren)氣(qi)刺叭時，含塵(chen)氣(qi)體(ti)受(shou)到(dao)氣(qi)流(liu)(liu)分布板以及折(zhe)流(liu)(liu)板的(de)(de)(de)(de)調(diao)整后，使氣(qi)流(liu)(liu)能較均勻地(di)進(jin)人(ren)電(dian)(dian)(dian)場。在(zai)橫(heng)斷面擴大的(de)(de)(de)(de)作(zuo)用下(xia)，氣(qi)流(liu)(liu)速(su)度迅速(su)降(jiang)低，其中有(you)些較重(zhong)的(de)(de)(de)(de)塵(chen)粒便失去速(su)度而沉降(jiang)下(xia)來。進(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)含塵(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)暈極(ji)(ji)通人(ren)高壓(ya)直流(liu)(liu)電(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)暈極(ji)(ji)附近(jin)產(chan)生電(dian)(dian)(dian)暈現象，使氣(qi)體(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)體(ti)中存在(zai)大量的(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)子(zi)和離子(zi)與進(jin)人(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)結(jie)合起來，使塵(chen)粒帶(dai)(dai)電(dian)(dian)(dian)，帶(dai)(dai)電(dian)(dian)(dian)塵(chen)粒在(zai)電(dian)(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用下(xia)趨向本設(she)備(bei)陽極(ji)(ji)(正極(ji)(ji)、本設(she)備(bei)采用負高壓(ya)制)和陰(yin)(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子(zi)分別沉積在(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設(she)備(bei)陰(yin)(yin)陽極(ji)(ji)振打系統(tong)的(de)(de)(de)(de)振打，使沉積在(zai)陰(yin)(yin)陽電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)(de)粉(fen)塵(chen)振落(luo)，進(jin)人(ren)集(ji)灰(hui)(hui)斗 通過排灰(hui)(hui)裝置放(fang)出，回(hui)收(shou)有(you)物料(liao)，被)凈化(hua)的(de)(de)(de)(de)氣(qi)體(ti)排入大氣(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)工作原理是(shi)利(li)用高壓電(dian)(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流(liu)(liu)中(zhong)的(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作用下(xia)(xia)與氣(qi)(qi)流(liu)(liu)分離(li)。負極(ji)(ji)由不同(tong)斷面(mian)形(xing)狀的(de)金屬導線制成(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同(tong)幾何形(xing)狀的(de)金屬板制成(cheng)，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)性(xing)能(neng)受粉塵(chen)(chen)(chen)性(xing)質、設備構(gou)造和煙(yan)氣(qi)(qi)流(liu)(liu)速等(deng)三個因素(su)的(de)影響。粉塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)指標，它對(dui)除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率有直接(jie)的(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)(chen)粒難(nan)以(yi)保持(chi)在集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)(qi)流(liu)(liu)。比電(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局(ju)部擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成(cheng)除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率下(xia)(xia)降。

電除塵(chen)器(qi)的基本原理(li)是(shi)利用電力捕(bu)集煙(yan)氣中的粉(fen)塵(chen)，主要包括以下四個(ge)相互有關的物(wu)理(li)過程: (1) 氣體(ti)的電離。(2) 粉(fen)塵(chen)的荷(he)電。(3) 荷(he)電粉(fen)塵(chen)向電極移動。(4) 荷(he)電粉(fen)塵(chen)的捕(bu)集。
