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)(dian)(dian)(dian)除塵(chen)(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)凈(jing)化(hua)工作上(shang)要是(shi)依(yi)靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和(he)沉(chen)淀(dian)兩個系(xi)統來(lai)完成的(de)(de)，當含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進人氣(qi)(qi)(qi)刺叭時(shi)，含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流分布(bu)板(ban)以(yi)及折(zhe)流板(ban)的(de)(de)調(diao)整后(hou)，使(shi)氣(qi)(qi)(qi)流能(neng)較均勻地進人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面擴大的(de)(de)作用(yong)(yong)下，氣(qi)(qi)(qi)流速度迅速降低(di)，其中有(you)些較重的(de)(de)塵(chen)(chen)粒(li)便失去速度而沉(chen)降下來(lai)。進人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含(han)(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通(tong)人高壓直(zhi)流電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象(xiang)，使(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中存(cun)在(zai)大量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離子，這些電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離子與進人電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用(yong)(yong)下趨向本設(she)(she)備陽極(ji)(ji)(正極(ji)(ji)、本設(she)(she)備采用(yong)(yong)負高壓制)和(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積在(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過(guo)設(she)(she)備陰(yin)陽極(ji)(ji)振(zhen)打系(xi)統的(de)(de)振(zhen)打，使(shi)沉(chen)積在(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉(fen)塵(chen)(chen)振(zhen)落(luo)，進人集灰斗 通(tong)過(guo)排(pai)灰裝置放出，回收有(you)物料，被)凈(jing)化(hua)的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排(pai)入大氣(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)工(gong)作原理是利用高(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發(fa)生電(dian)(dian)(dian)(dian)離，氣(qi)流(liu)(liu)(liu)中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場(chang)作用下與氣(qi)流(liu)(liu)(liu)分離。負極由不(bu)同斷面形狀的(de)(de)金(jin)屬導線制成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由不(bu)同幾何形狀的(de)(de)金(jin)屬板(ban)制成(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)性(xing)(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)性(xing)(xing)質、設備構造和煙氣(qi)流(liu)(liu)(liu)速等三個因素的(de)(de)影(ying)響(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)性(xing)(xing)的(de)(de)指標，它對除(chu)(chu)塵(chen)(chen)(chen)(chen)效率有直接的(de)(de)影(ying)響(xiang)。比電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒(li)難以保持(chi)在集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上(shang)，致使其重返氣(qi)流(liu)(liu)(liu)。比電(dian)(dian)(dian)(dian)阻過高(gao)，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)壓(ya)(ya)梯度會產生局部擊穿(chuan)和放電(dian)(dian)(dian)(dian)現象。這(zhe)些情況(kuang)都(dou)會造成(cheng)除(chu)(chu)塵(chen)(chen)(chen)(chen)效率下降(jiang)。

電(dian)除塵(chen)器的(de)(de)基本原理是(shi)利用電(dian)力(li)捕集(ji)煙氣(qi)中的(de)(de)粉(fen)塵(chen)，主(zhu)要包括以下四個相互有關的(de)(de)物(wu)理過(guo)程(cheng): (1) 氣(qi)體的(de)(de)電(dian)離(li)。(2) 粉(fen)塵(chen)的(de)(de)荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)向(xiang)電(dian)極移動。(4) 荷電(dian)粉(fen)塵(chen)的(de)(de)捕集(ji)。
