XWD型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(jing)(jing)電(dian)(dian)(dian)(dian)除塵(chen)器是(shi)以(yi)(yi)靜(jing)(jing)電(dian)(dian)(dian)(dian)凈(jing)化法來(lai)收(shou)捕廢氣(qi)中的(de)粉(fen)塵(chen)，它(ta)的(de)凈(jing)化工作上(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)和(he)沉(chen)淀兩(liang)個(ge)系統(tong)來(lai)完成的(de)，當含(han)塵(chen)氣(qi)體(ti)進(jin)人(ren)氣(qi)刺叭(ba)時，含(han)塵(chen)氣(qi)體(ti)受(shou)到氣(qi)流(liu)(liu)分布(bu)板以(yi)(yi)及折流(liu)(liu)板的(de)調整后，使氣(qi)流(liu)(liu)能較(jiao)均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)。在(zai)橫斷面擴大(da)的(de)作用下，氣(qi)流(liu)(liu)速度(du)(du)迅速降低，其中有些(xie)較(jiao)重的(de)塵(chen)粒便失去速度(du)(du)而沉(chen)降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)的(de)含(han)塵(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)通人(ren)高(gao)壓(ya)直流(liu)(liu)電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使氣(qi)體(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)氣(qi)體(ti)中存在(zai)大(da)量的(de)電(dian)(dian)(dian)(dian)子和(he)離子，這些(xie)電(dian)(dian)(dian)(dian)子和(he)離子與進(jin)人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)的(de)粉(fen)塵(chen)結合起來(lai)，使塵(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒在(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)(chang)力(li)的(de)作用下趨向本設(she)備陽極(ji)(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)(ji)、本設(she)備采用負(fu)高(gao)壓(ya)制)和(he)陰(yin)(yin)極(ji)(ji)(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分別沉(chen)積在(zai)相(xiang)應的(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)，通過(guo)設(she)備陰(yin)(yin)陽極(ji)(ji)(ji)(ji)(ji)振(zhen)(zhen)打(da)系統(tong)的(de)振(zhen)(zhen)打(da)，使沉(chen)積在(zai)陰(yin)(yin)陽電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上(shang)的(de)粉(fen)塵(chen)振(zhen)(zhen)落，進(jin)人(ren)集灰斗 通過(guo)排灰裝置放出，回收(shou)有物(wu)料，被)凈(jing)化的(de)氣(qi)體(ti)排入大(da)氣(qi)。

工作原理

靜電(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)工作(zuo)原理(li)是利(li)用高壓(ya)電(dian)場使煙氣(qi)發生電(dian)離(li)，氣(qi)流(liu)中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)荷電(dian)在(zai)電(dian)場作(zuo)用下與氣(qi)流(liu)分離(li)。負極(ji)由不(bu)(bu)同(tong)斷面形(xing)狀的(de)(de)(de)金屬(shu)導線制成(cheng)，叫放(fang)電(dian)電(dian)極(ji)。正極(ji)由不(bu)(bu)同(tong)幾何形(xing)狀的(de)(de)(de)金屬(shu)板制成(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)極(ji)。靜電(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)性(xing)能(neng)受粉塵(chen)(chen)(chen)(chen)(chen)性(xing)質、設備構造和煙氣(qi)流(liu)速等三(san)個因素的(de)(de)(de)影響(xiang)(xiang)。粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)阻是評(ping)價(jia)導電(dian)性(xing)的(de)(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)(chen)效率有直接的(de)(de)(de)影響(xiang)(xiang)。比(bi)電(dian)阻過低(di)，塵(chen)(chen)(chen)(chen)(chen)粒(li)難以保持在(zai)集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)極(ji)上，致(zhi)使其重返氣(qi)流(liu)。比(bi)電(dian)阻過高，到達集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒(li)電(dian)荷不(bu)(bu)易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)壓(ya)梯度會產生局部擊穿和放(fang)電(dian)現象。這些情況都(dou)會造成(cheng)除塵(chen)(chen)(chen)(chen)(chen)效率下降(jiang)。

電(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)基(ji)本(ben)原理(li)是利用(yong)電(dian)(dian)力(li)捕集(ji)煙氣中的(de)(de)(de)粉塵(chen)(chen)，主要包(bao)括以下四個相互有關的(de)(de)(de)物理(li)過程(cheng): (1) 氣體的(de)(de)(de)電(dian)(dian)離。(2) 粉塵(chen)(chen)的(de)(de)(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉塵(chen)(chen)的(de)(de)(de)捕集(ji)。
