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)靜電(dian)(dian)(dian)除塵(chen)(chen)器是以靜電(dian)(dian)(dian)凈化(hua)法來(lai)(lai)收(shou)捕廢氣(qi)(qi)中的(de)粉(fen)塵(chen)(chen)，它的(de)凈化(hua)工作上要是依靠電(dian)(dian)(dian)暈(yun)極(ji)(ji)和沉淀兩個系(xi)統來(lai)(lai)完成的(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體(ti)進(jin)(jin)人氣(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流分布板以及(ji)折流板的(de)調整后，使(shi)(shi)氣(qi)(qi)流能較均勻地進(jin)(jin)人電(dian)(dian)(dian)場(chang)。在(zai)(zai)(zai)橫斷面(mian)擴大的(de)作用下(xia)，氣(qi)(qi)流速度(du)迅(xun)速降低，其中有些(xie)較重(zhong)的(de)塵(chen)(chen)粒便失去速度(du)而沉降下(xia)來(lai)(lai)。進(jin)(jin)人電(dian)(dian)(dian)場(chang)的(de)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)(tong)人高(gao)壓(ya)直流電(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)暈(yun)極(ji)(ji)附近(jin)產生電(dian)(dian)(dian)暈(yun)現象，使(shi)(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)氣(qi)(qi)體(ti)中存在(zai)(zai)(zai)大量(liang)的(de)電(dian)(dian)(dian)子和離子，這些(xie)電(dian)(dian)(dian)子和離子與進(jin)(jin)人電(dian)(dian)(dian)場(chang)的(de)粉(fen)塵(chen)(chen)結合起來(lai)(lai)，使(shi)(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)(zai)電(dian)(dian)(dian)場(chang)力的(de)作用下(xia)趨向本(ben)設備陽極(ji)(ji)(正(zheng)極(ji)(ji)、本(ben)設備采(cai)用負高(gao)壓(ya)制)和陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子分別沉積在(zai)(zai)(zai)相應的(de)電(dian)(dian)(dian)極(ji)(ji)上，通(tong)(tong)過設備陰(yin)陽極(ji)(ji)振打(da)(da)系(xi)統的(de)振打(da)(da)，使(shi)(shi)沉積在(zai)(zai)(zai)陰(yin)陽電(dian)(dian)(dian)極(ji)(ji)上的(de)粉(fen)塵(chen)(chen)振落，進(jin)(jin)人集灰斗 通(tong)(tong)過排灰裝置放出，回收(shou)有物料(liao)，被)凈化(hua)的(de)氣(qi)(qi)體(ti)排入大氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)(de)工作原(yuan)理是(shi)利(li)用(yong)高(gao)(gao)壓電(dian)(dian)(dian)場使(shi)煙氣(qi)發生電(dian)(dian)(dian)離，氣(qi)流(liu)(liu)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用(yong)下(xia)(xia)與(yu)氣(qi)流(liu)(liu)分離。負極(ji)由(you)不同斷面形狀(zhuang)的(de)(de)(de)(de)金屬導線制(zhi)成，叫放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由(you)不同幾何形狀(zhuang)的(de)(de)(de)(de)金屬板制(zhi)成，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)(de)性(xing)能受粉塵(chen)(chen)(chen)性(xing)質、設備構造和(he)煙氣(qi)流(liu)(liu)速(su)等三(san)個因素的(de)(de)(de)(de)影(ying)響。粉塵(chen)(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)指(zhi)標，它對除塵(chen)(chen)(chen)效率有直接的(de)(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒難以(yi)保(bao)持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上(shang)，致使(shi)其重返氣(qi)流(liu)(liu)。比電(dian)(dian)(dian)阻(zu)過高(gao)(gao)，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷(he)不易放(fang)(fang)出(chu)，在塵(chen)(chen)(chen)層(ceng)之間形成電(dian)(dian)(dian)壓梯度會產(chan)生局部擊穿(chuan)和(he)放(fang)(fang)電(dian)(dian)(dian)現(xian)象。這些情況都會造成除塵(chen)(chen)(chen)效率下(xia)(xia)降。

電(dian)除塵器的(de)基本原理是利用(yong)電(dian)力捕集煙氣中的(de)粉(fen)塵，主(zhu)要包括以下四個(ge)相(xiang)互有關的(de)物理過(guo)程: (1) 氣體的(de)電(dian)離。(2) 粉(fen)塵的(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵向(xiang)電(dian)極(ji)移(yi)動(dong)。(4) 荷電(dian)粉(fen)塵的(de)捕集。
