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)式靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)凈(jing)化法來(lai)收捕廢氣(qi)(qi)中的(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)凈(jing)化工作(zuo)上(shang)要是(shi)依(yi)靠(kao)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)和(he)(he)沉淀兩個系統(tong)(tong)來(lai)完成的(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)進(jin)人(ren)氣(qi)(qi)刺(ci)叭時，含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)流(liu)分(fen)布(bu)板以及折流(liu)板的(de)(de)調整后，使氣(qi)(qi)流(liu)能較均勻地(di)進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場。在橫斷(duan)面擴(kuo)大(da)的(de)(de)作(zuo)用(yong)下(xia)，氣(qi)(qi)流(liu)速(su)度迅速(su)降低，其(qi)中有些(xie)較重的(de)(de)塵(chen)(chen)(chen)粒便失去(qu)速(su)度而(er)沉降下(xia)來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)通人(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現象，使氣(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)(de)氣(qi)(qi)體(ti)(ti)(ti)中存在大(da)量(liang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)子和(he)(he)離子，這些(xie)電(dian)(dian)(dian)(dian)(dian)子和(he)(he)離子與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)，使塵(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作(zuo)用(yong)下(xia)趨向本設(she)備陽極(ji)(正極(ji)、本設(she)備采用(yong)負高壓(ya)制)和(he)(he)陰(yin)極(ji)(負極(ji)) ， 釋(shi)放出(chu)電(dian)(dian)(dian)(dian)(dian)子分(fen)別沉積在相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通過(guo)設(she)備陰(yin)陽極(ji)振(zhen)打系統(tong)(tong)的(de)(de)振(zhen)打，使沉積在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)粉塵(chen)(chen)(chen)振(zhen)落，進(jin)人(ren)集灰斗 通過(guo)排灰裝置(zhi)放出(chu)，回收有物(wu)料(liao)，被)凈(jing)化的(de)(de)氣(qi)(qi)體(ti)(ti)(ti)排入(ru)大(da)氣(qi)(qi)。

工作原理

靜電(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)工作(zuo)原理是(shi)利用(yong)高壓電(dian)場使(shi)煙氣(qi)發生(sheng)電(dian)離，氣(qi)流(liu)(liu)中的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)在(zai)(zai)電(dian)場作(zuo)用(yong)下與(yu)氣(qi)流(liu)(liu)分(fen)離。負(fu)極(ji)由不同(tong)斷面形狀的(de)(de)金屬導(dao)線(xian)制成(cheng)，叫(jiao)放(fang)電(dian)電(dian)極(ji)。正極(ji)由不同(tong)幾何形狀的(de)(de)金屬板制成(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)(chen)電(dian)極(ji)。靜電(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)性(xing)能受粉(fen)(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設備構造(zao)和煙氣(qi)流(liu)(liu)速(su)等三(san)個因素(su)的(de)(de)影響(xiang)。粉(fen)(fen)塵(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)阻(zu)是(shi)評價導(dao)電(dian)性(xing)的(de)(de)指標(biao)，它對(dui)除(chu)塵(chen)(chen)(chen)(chen)效率有直接的(de)(de)影響(xiang)。比(bi)電(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)(chen)粒難以保(bao)持在(zai)(zai)集(ji)塵(chen)(chen)(chen)(chen)電(dian)極(ji)上，致使(shi)其重返氣(qi)流(liu)(liu)。比(bi)電(dian)阻(zu)過(guo)高，到達(da)集(ji)塵(chen)(chen)(chen)(chen)電(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)荷(he)不易放(fang)出，在(zai)(zai)塵(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)壓梯(ti)度(du)會(hui)產(chan)生(sheng)局部擊穿和放(fang)電(dian)現(xian)象(xiang)。這些情況都會(hui)造(zao)成(cheng)除(chu)塵(chen)(chen)(chen)(chen)效率下降(jiang)。

電除塵(chen)器的(de)基本原理是利用電力捕(bu)集煙氣(qi)中的(de)粉(fen)塵(chen)，主要包括以下四(si)個相互有關的(de)物理過程: (1) 氣(qi)體的(de)電離。(2) 粉(fen)塵(chen)的(de)荷(he)電。(3) 荷(he)電粉(fen)塵(chen)向電極(ji)移動。(4) 荷(he)電粉(fen)塵(chen)的(de)捕(bu)集。
