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。

臥式靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來收捕廢氣(qi)(qi)(qi)中的(de)粉(fen)塵(chen)(chen)(chen)(chen)，它的(de)凈(jing)化(hua)工作上(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)和(he)沉淀兩個(ge)系統來完成的(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)進人(ren)(ren)氣(qi)(qi)(qi)刺叭(ba)時，含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)受到(dao)氣(qi)(qi)(qi)流分(fen)布板以及折流板的(de)調整后，使氣(qi)(qi)(qi)流能較(jiao)均(jun)勻地進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴(kuo)大(da)(da)的(de)作用(yong)下，氣(qi)(qi)(qi)流速度迅速降低，其中有些較(jiao)重的(de)塵(chen)(chen)(chen)(chen)粒(li)便失(shi)去速度而沉降下來。進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)含塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)通(tong)人(ren)(ren)高壓(ya)直流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象(xiang)，使氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)氣(qi)(qi)(qi)體(ti)中存在(zai)大(da)(da)量的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)粉(fen)塵(chen)(chen)(chen)(chen)結(jie)合(he)起來，使塵(chen)(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)作用(yong)下趨(qu)向本設(she)備陽(yang)極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設(she)備采用(yong)負(fu)高壓(ya)制)和(he)陰極(ji)(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別沉積在(zai)相應的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)，通(tong)過設(she)備陰陽(yang)極(ji)(ji)(ji)(ji)振(zhen)打系統的(de)振(zhen)打，使沉積在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)的(de)粉(fen)塵(chen)(chen)(chen)(chen)振(zhen)落，進人(ren)(ren)集灰斗 通(tong)過排灰裝(zhuang)置放(fang)出，回(hui)收有物(wu)料，被)凈(jing)化(hua)的(de)氣(qi)(qi)(qi)體(ti)排入大(da)(da)氣(qi)(qi)(qi)。

工作(zuo)原(yuan)理

靜(jing)(jing)電(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)工(gong)作原(yuan)理是(shi)利(li)用高壓電(dian)(dian)場使(shi)煙(yan)氣發(fa)生(sheng)電(dian)(dian)離，氣流中的(de)(de)粉塵(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場作用下與氣流分(fen)離。負(fu)極(ji)由不同斷面形(xing)狀的(de)(de)金屬導線制(zhi)成(cheng)，叫(jiao)(jiao)放(fang)電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不同幾何形(xing)狀的(de)(de)金屬板制(zhi)成(cheng)，叫(jiao)(jiao)集(ji)(ji)塵(chen)(chen)電(dian)(dian)極(ji)。靜(jing)(jing)電(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)性能受(shou)粉塵(chen)(chen)性質、設備構造和(he)煙(yan)氣流速(su)等三個因素的(de)(de)影響。粉塵(chen)(chen)的(de)(de)比電(dian)(dian)阻(zu)是(shi)評(ping)價導電(dian)(dian)性的(de)(de)指標，它對(dui)除(chu)塵(chen)(chen)效率(lv)有直接的(de)(de)影響。比電(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)粒難(nan)以保持在(zai)集(ji)(ji)塵(chen)(chen)電(dian)(dian)極(ji)上，致(zhi)使(shi)其重返氣流。比電(dian)(dian)阻(zu)過(guo)高，到達集(ji)(ji)塵(chen)(chen)電(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)層(ceng)之間形(xing)成(cheng)電(dian)(dian)壓梯(ti)度會產生(sheng)局部擊(ji)穿和(he)放(fang)電(dian)(dian)現(xian)象。這些情況都會造成(cheng)除(chu)塵(chen)(chen)效率(lv)下降。

電除塵器的(de)基本原理是(shi)利用電力捕集(ji)煙氣(qi)中(zhong)的(de)粉(fen)(fen)塵，主要包括以下四個相互有關的(de)物理過程(cheng): (1) 氣(qi)體的(de)電離。(2) 粉(fen)(fen)塵的(de)荷(he)電。(3) 荷(he)電粉(fen)(fen)塵向電極移動。(4) 荷(he)電粉(fen)(fen)塵的(de)捕集(ji)。
