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(chu)塵(chen)(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)凈(jing)化法(fa)來(lai)收(shou)捕廢(fei)氣(qi)中(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)凈(jing)化工(gong)作上(shang)要是依靠電(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)(he)沉淀(dian)兩(liang)個系(xi)(xi)統(tong)來(lai)完(wan)成的(de)(de)(de)，當含(han)(han)(han)塵(chen)(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)(ti)(ti)進人(ren)(ren)氣(qi)刺(ci)叭時，含(han)(han)(han)塵(chen)(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)(ti)(ti)受到(dao)氣(qi)流(liu)分布板以及折流(liu)板的(de)(de)(de)調整(zheng)后(hou)，使(shi)氣(qi)流(liu)能較(jiao)均勻(yun)地進人(ren)(ren)電(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫(heng)斷面擴(kuo)大的(de)(de)(de)作用下(xia)，氣(qi)流(liu)速度(du)迅速降(jiang)低，其中(zhong)有些較(jiao)重(zhong)的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)便失(shi)去速度(du)而(er)沉降(jiang)下(xia)來(lai)。進人(ren)(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)含(han)(han)(han)塵(chen)(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)(ti)(ti)由于電(dian)(dian)(dian)暈極(ji)(ji)(ji)通(tong)人(ren)(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)暈現(xian)象(xiang)，使(shi)氣(qi)體(ti)(ti)(ti)(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后(hou)的(de)(de)(de)氣(qi)體(ti)(ti)(ti)(ti)(ti)中(zhong)存在(zai)(zai)大量的(de)(de)(de)電(dian)(dian)(dian)子和(he)(he)離子，這些電(dian)(dian)(dian)子和(he)(he)離子與進人(ren)(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)(chen)(chen)粒(li)帶(dai)(dai)電(dian)(dian)(dian)，帶(dai)(dai)電(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)作用下(xia)趨向本設(she)(she)備(bei)陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設(she)(she)備(bei)采用負高壓(ya)制)和(he)(he)陰(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子分別沉積在(zai)(zai)相(xiang)應(ying)的(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通(tong)過(guo)設(she)(she)備(bei)陰(yin)陽極(ji)(ji)(ji)振(zhen)打系(xi)(xi)統(tong)的(de)(de)(de)振(zhen)打，使(shi)沉積在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)振(zhen)落，進人(ren)(ren)集灰(hui)斗 通(tong)過(guo)排(pai)灰(hui)裝置(zhi)放(fang)出，回(hui)收(shou)有物料，被)凈(jing)化的(de)(de)(de)氣(qi)體(ti)(ti)(ti)(ti)(ti)排(pai)入大氣(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)工作(zuo)原(yuan)理是利(li)用(yong)高壓電(dian)(dian)(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)(dian)(dian)離，氣流(liu)(liu)中的(de)(de)粉(fen)塵(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作(zuo)用(yong)下與(yu)氣流(liu)(liu)分離。負極(ji)(ji)由不同斷面形(xing)狀(zhuang)的(de)(de)金(jin)屬導線制成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同幾何形(xing)狀(zhuang)的(de)(de)金(jin)屬板(ban)制成(cheng)，叫集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)性(xing)能受粉(fen)塵(chen)性(xing)質、設(she)備構造和煙氣流(liu)(liu)速(su)等三(san)個因素的(de)(de)影響。粉(fen)塵(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)是評價(jia)導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指(zhi)標，它對除塵(chen)效率(lv)有直接的(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)粒難(nan)以保持在集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣流(liu)(liu)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)高，到(dao)達集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不易放(fang)出，在塵(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會(hui)(hui)產生局部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)現象。這些情況都(dou)會(hui)(hui)造成(cheng)除塵(chen)效率(lv)下降。

電(dian)除塵(chen)(chen)(chen)器的基本原理是利用電(dian)力捕集煙氣中(zhong)的粉(fen)(fen)塵(chen)(chen)(chen)，主要包括以下四個相(xiang)互有關的物理過(guo)程: (1) 氣體(ti)的電(dian)離。(2) 粉(fen)(fen)塵(chen)(chen)(chen)的荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)(fen)塵(chen)(chen)(chen)向(xiang)電(dian)極移動。(4) 荷(he)電(dian)粉(fen)(fen)塵(chen)(chen)(chen)的捕集。
