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(jing)(jing)化法(fa)來(lai)收捕廢(fei)氣(qi)中(zhong)(zhong)的(de)(de)粉(fen)塵(chen)，它的(de)(de)凈(jing)(jing)化工作(zuo)上(shang)要(yao)是依靠電(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)沉淀兩個系統來(lai)完成(cheng)的(de)(de)，當含塵(chen)氣(qi)體(ti)進(jin)人(ren)(ren)(ren)氣(qi)刺(ci)叭時，含塵(chen)氣(qi)體(ti)受到氣(qi)流(liu)(liu)分布(bu)板以及(ji)折流(liu)(liu)板的(de)(de)調整(zheng)后(hou)，使氣(qi)流(liu)(liu)能(neng)較均勻地進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場。在(zai)橫斷(duan)面擴(kuo)大(da)的(de)(de)作(zuo)用(yong)下，氣(qi)流(liu)(liu)速度迅(xun)速降(jiang)低，其中(zhong)(zhong)有(you)些(xie)(xie)較重(zhong)的(de)(de)塵(chen)粒(li)便(bian)失去速度而沉降(jiang)下來(lai)。進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場的(de)(de)含塵(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)(tong)人(ren)(ren)(ren)高(gao)壓直流(liu)(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)暈(yun)現象，使氣(qi)體(ti)電(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)離(li)(li)后(hou)的(de)(de)氣(qi)體(ti)中(zhong)(zhong)存在(zai)大(da)量的(de)(de)電(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)，這些(xie)(xie)電(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)與進(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場的(de)(de)粉(fen)塵(chen)結(jie)合起(qi)來(lai)，使塵(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒(li)在(zai)電(dian)(dian)(dian)場力的(de)(de)作(zuo)用(yong)下趨向本設備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本設備(bei)采用(yong)負高(gao)壓制)和(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子(zi)分別沉積在(zai)相應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)(tong)過設備(bei)陰(yin)陽(yang)極(ji)(ji)振打(da)(da)系統的(de)(de)振打(da)(da)，使沉積在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉(fen)塵(chen)振落，進(jin)人(ren)(ren)(ren)集灰(hui)斗 通(tong)(tong)過排灰(hui)裝置(zhi)放出(chu)，回(hui)收有(you)物料，被)凈(jing)(jing)化的(de)(de)氣(qi)體(ti)排入大(da)氣(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)工作原理是利用(yong)(yong)高壓(ya)電(dian)(dian)(dian)場(chang)使煙氣(qi)(qi)發生電(dian)(dian)(dian)離，氣(qi)(qi)流(liu)(liu)中的(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作用(yong)(yong)下與氣(qi)(qi)流(liu)(liu)分離。負(fu)極由不同斷(duan)面形(xing)狀的(de)(de)金屬(shu)導線制成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由不同幾何形(xing)狀的(de)(de)金屬(shu)板制成(cheng)，叫(jiao)集(ji)塵(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)性(xing)能(neng)受粉塵(chen)(chen)性(xing)質、設備構造(zao)和煙氣(qi)(qi)流(liu)(liu)速等三個因素的(de)(de)影響(xiang)(xiang)。粉塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)效率有直接的(de)(de)影響(xiang)(xiang)。比電(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)極上(shang)，致使其重返氣(qi)(qi)流(liu)(liu)。比電(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不易放(fang)出(chu)，在塵(chen)(chen)層(ceng)之間形(xing)成(cheng)電(dian)(dian)(dian)壓(ya)梯度會(hui)(hui)產生局(ju)部擊穿和放(fang)電(dian)(dian)(dian)現象。這(zhe)些(xie)情況都會(hui)(hui)造(zao)成(cheng)除(chu)(chu)塵(chen)(chen)效率下降。

電(dian)(dian)除塵(chen)(chen)器的(de)基本原理是利用電(dian)(dian)力捕(bu)集(ji)煙(yan)氣中的(de)粉塵(chen)(chen)，主要包括以下四(si)個相互有關的(de)物理過程(cheng): (1) 氣體的(de)電(dian)(dian)離(li)。(2) 粉塵(chen)(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)極移動(dong)。(4) 荷電(dian)(dian)粉塵(chen)(chen)的(de)捕(bu)集(ji)。
