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)除塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法來(lai)收捕廢(fei)氣(qi)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)(de)凈(jing)(jing)化(hua)工作(zuo)上(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)(ji)(ji)和(he)(he)(he)(he)沉淀兩個(ge)系統來(lai)完(wan)成(cheng)的(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)體(ti)進(jin)人氣(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)體(ti)受到氣(qi)流(liu)分布板以及折流(liu)板的(de)(de)(de)(de)調整后，使(shi)氣(qi)流(liu)能較均勻地進(jin)人電(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)橫斷面擴大的(de)(de)(de)(de)作(zuo)用(yong)下(xia)，氣(qi)流(liu)速度迅速降低，其中有(you)些(xie)較重的(de)(de)(de)(de)塵(chen)(chen)(chen)粒便失去速度而沉降下(xia)來(lai)。進(jin)人電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)(ji)(ji)通(tong)(tong)人高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)(yun)(yun)現象，使(shi)氣(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)離(li)(li)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)(dian)子和(he)(he)(he)(he)離(li)(li)子，這些(xie)電(dian)(dian)(dian)(dian)子和(he)(he)(he)(he)離(li)(li)子與(yu)進(jin)人電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結(jie)合起來(lai)，使(shi)塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)作(zuo)用(yong)下(xia)趨向(xiang)本設(she)備(bei)陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設(she)備(bei)采(cai)用(yong)負高壓(ya)制)和(he)(he)(he)(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)子分別沉積在(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通(tong)(tong)過設(she)備(bei)陰陽(yang)極(ji)(ji)(ji)振(zhen)(zhen)打(da)系統的(de)(de)(de)(de)振(zhen)(zhen)打(da)，使(shi)沉積在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)(zhen)落，進(jin)人集灰斗 通(tong)(tong)過排灰裝置(zhi)放出，回收有(you)物料(liao)，被)凈(jing)(jing)化(hua)的(de)(de)(de)(de)氣(qi)體(ti)排入大氣(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)(de)工作(zuo)原理(li)是利用(yong)高(gao)壓電(dian)(dian)(dian)場使煙(yan)氣發生電(dian)(dian)(dian)離，氣流(liu)中的(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)場作(zuo)用(yong)下與氣流(liu)分離。負極由不(bu)同斷面形(xing)狀(zhuang)的(de)(de)(de)(de)(de)金(jin)屬(shu)導(dao)線制(zhi)(zhi)成(cheng)，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由不(bu)同幾何形(xing)狀(zhuang)的(de)(de)(de)(de)(de)金(jin)屬(shu)板制(zhi)(zhi)成(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)(de)性能(neng)受粉塵(chen)(chen)(chen)(chen)性質、設備構(gou)造(zao)和煙(yan)氣流(liu)速等三個因素(su)的(de)(de)(de)(de)(de)影(ying)響(xiang)。粉塵(chen)(chen)(chen)(chen)的(de)(de)(de)(de)(de)比電(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)性的(de)(de)(de)(de)(de)指標，它對(dui)除塵(chen)(chen)(chen)(chen)效率有直(zhi)接的(de)(de)(de)(de)(de)影(ying)響(xiang)。比電(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)(chen)(chen)粒難以(yi)保(bao)持(chi)在(zai)(zai)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極上，致(zhi)使其重返(fan)氣流(liu)。比電(dian)(dian)(dian)阻過(guo)高(gao)，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷(he)不(bu)易放出，在(zai)(zai)塵(chen)(chen)(chen)(chen)層之(zhi)間形(xing)成(cheng)電(dian)(dian)(dian)壓梯度會產生局部擊穿和放電(dian)(dian)(dian)現(xian)象。這些情(qing)況都會造(zao)成(cheng)除塵(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)除塵(chen)器的基本原理是利用電(dian)(dian)力捕集(ji)煙氣中(zhong)的粉塵(chen)，主要(yao)包括以下四個相互有(you)關的物理過程: (1) 氣體(ti)的電(dian)(dian)離(li)。(2) 粉塵(chen)的荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵(chen)向(xiang)電(dian)(dian)極移(yi)動。(4) 荷(he)電(dian)(dian)粉塵(chen)的捕集(ji)。
