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(wo)式(shi)靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)凈化(hua)法(fa)來(lai)收(shou)捕廢氣(qi)(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)(de)凈化(hua)工作(zuo)(zuo)上(shang)(shang)要是依靠電(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)沉(chen)淀兩(liang)個系統來(lai)完(wan)成的(de)(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)進(jin)(jin)人氣(qi)(qi)(qi)(qi)(qi)刺叭(ba)時，含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)(qi)流(liu)分(fen)(fen)布板以(yi)及折流(liu)板的(de)(de)(de)(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)(qi)(qi)流(liu)能較均(jun)勻地(di)進(jin)(jin)人電(dian)(dian)(dian)場。在橫斷面擴大(da)的(de)(de)(de)(de)(de)(de)作(zuo)(zuo)用(yong)下(xia)，氣(qi)(qi)(qi)(qi)(qi)流(liu)速(su)度(du)迅(xun)速(su)降低(di)，其中有些較重的(de)(de)(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒便失去速(su)度(du)而沉(chen)降下(xia)來(lai)。進(jin)(jin)人電(dian)(dian)(dian)場的(de)(de)(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)暈極(ji)(ji)(ji)通(tong)人高壓(ya)直流(liu)電(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)暈現象(xiang)，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)中存在大(da)量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)子和(he)離子，這(zhe)些電(dian)(dian)(dian)子和(he)離子與進(jin)(jin)人電(dian)(dian)(dian)場的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)結(jie)合起來(lai)，使(shi)塵(chen)(chen)(chen)(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒在電(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)(de)作(zuo)(zuo)用(yong)下(xia)趨向本(ben)設備陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)設備采(cai)用(yong)負高壓(ya)制)和(he)陰(yin)(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子分(fen)(fen)別沉(chen)積在相應的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)，通(tong)過設備陰(yin)(yin)陽極(ji)(ji)(ji)振(zhen)打系統的(de)(de)(de)(de)(de)(de)振(zhen)打，使(shi)沉(chen)積在陰(yin)(yin)陽電(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)(shang)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)振(zhen)落，進(jin)(jin)人集(ji)灰(hui)斗 通(tong)過排灰(hui)裝置放出，回(hui)收(shou)有物(wu)料，被)凈化(hua)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)排入(ru)大(da)氣(qi)(qi)(qi)(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)工作原理(li)是利用高壓電(dian)(dian)(dian)(dian)場(chang)使(shi)煙氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)作用下與氣(qi)流分離。負極(ji)(ji)由(you)不同(tong)斷(duan)面形狀的(de)金屬導(dao)線制(zhi)成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由(you)不同(tong)幾何形狀的(de)金屬板制(zhi)成(cheng)，叫(jiao)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)性能受粉塵(chen)(chen)(chen)(chen)性質、設備構造(zao)和煙氣(qi)流速等三個因(yin)素(su)的(de)影響。粉塵(chen)(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)(dian)性的(de)指標，它(ta)對(dui)除(chu)塵(chen)(chen)(chen)(chen)效率(lv)有直接的(de)影響。比電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致使(shi)其重返氣(qi)流。比電(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)層(ceng)之間形成(cheng)電(dian)(dian)(dian)(dian)壓梯(ti)度(du)會(hui)產生(sheng)局部擊穿(chuan)和放(fang)電(dian)(dian)(dian)(dian)現象。這(zhe)些情況都會(hui)造(zao)成(cheng)除(chu)塵(chen)(chen)(chen)(chen)效率(lv)下降。

電除塵(chen)(chen)器的(de)(de)基本原理(li)是利用電力捕(bu)集(ji)煙(yan)氣中的(de)(de)粉塵(chen)(chen)，主要包括以(yi)下四個相互有關的(de)(de)物理(li)過(guo)程: (1) 氣體的(de)(de)電離。(2) 粉塵(chen)(chen)的(de)(de)荷(he)電。(3) 荷(he)電粉塵(chen)(chen)向電極移動。(4) 荷(he)電粉塵(chen)(chen)的(de)(de)捕(bu)集(ji)。
