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(shi)靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來收(shou)捕(bu)廢氣(qi)(qi)(qi)中的(de)(de)粉(fen)塵(chen)，它的(de)(de)凈(jing)化(hua)工作(zuo)(zuo)(zuo)上(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)和(he)(he)沉(chen)淀兩(liang)個系(xi)統(tong)來完(wan)成的(de)(de)，當(dang)含塵(chen)氣(qi)(qi)(qi)體(ti)進(jin)人氣(qi)(qi)(qi)刺叭時(shi)，含塵(chen)氣(qi)(qi)(qi)體(ti)受到(dao)氣(qi)(qi)(qi)流(liu)(liu)(liu)分布(bu)板以及折流(liu)(liu)(liu)板的(de)(de)調整后(hou)，使氣(qi)(qi)(qi)流(liu)(liu)(liu)能較均勻(yun)地進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)橫斷(duan)面擴(kuo)大(da)的(de)(de)作(zuo)(zuo)(zuo)用(yong)(yong)下，氣(qi)(qi)(qi)流(liu)(liu)(liu)速(su)度迅速(su)降低，其(qi)中有(you)些較重的(de)(de)塵(chen)粒便(bian)失(shi)去速(su)度而(er)沉(chen)降下來。進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)含塵(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)通(tong)人高壓直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)氣(qi)(qi)(qi)體(ti)中存在(zai)大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)(he)離(li)子，這些電(dian)(dian)(dian)(dian)(dian)(dian)子和(he)(he)離(li)子與進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉(fen)塵(chen)結合起(qi)來，使塵(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作(zuo)(zuo)(zuo)用(yong)(yong)下趨向本設備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本設備(bei)采(cai)用(yong)(yong)負高壓制)和(he)(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積(ji)在(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過(guo)(guo)設備(bei)陰陽(yang)極(ji)(ji)振(zhen)打系(xi)統(tong)的(de)(de)振(zhen)打，使沉(chen)積(ji)在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉(fen)塵(chen)振(zhen)落，進(jin)人集灰斗 通(tong)過(guo)(guo)排(pai)灰裝置放(fang)出，回收(shou)有(you)物料，被)凈(jing)化(hua)的(de)(de)氣(qi)(qi)(qi)體(ti)排(pai)入大(da)氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)工作原理是(shi)利用高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場使(shi)煙(yan)(yan)氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流(liu)中的(de)(de)粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場作用下與氣(qi)(qi)流(liu)分離(li)。負極由不(bu)同斷面(mian)形(xing)(xing)狀的(de)(de)金屬導線制(zhi)成(cheng)(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極。正極由不(bu)同幾何形(xing)(xing)狀的(de)(de)金屬板制(zhi)成(cheng)(cheng)，叫集(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)性能受粉塵(chen)(chen)性質、設備(bei)構造和煙(yan)(yan)氣(qi)(qi)流(liu)速等三個因素的(de)(de)影(ying)響。粉塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標，它對除塵(chen)(chen)效率有直接的(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以(yi)保持在集(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極上，致使(shi)其重返氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到(dao)達集(ji)(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易放出，在塵(chen)(chen)層之(zhi)間形(xing)(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會(hui)(hui)產生(sheng)局部(bu)擊(ji)穿和放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)現(xian)象。這些(xie)情況(kuang)都會(hui)(hui)造成(cheng)(cheng)除塵(chen)(chen)效率下降(jiang)。

電(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)(de)基本原(yuan)理是利用電(dian)(dian)力捕(bu)集煙氣(qi)(qi)中(zhong)的(de)(de)(de)粉塵(chen)(chen)(chen)，主要包括以下四個相互有關的(de)(de)(de)物(wu)理過程(cheng): (1) 氣(qi)(qi)體(ti)的(de)(de)(de)電(dian)(dian)離。(2) 粉塵(chen)(chen)(chen)的(de)(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵(chen)(chen)(chen)向電(dian)(dian)極移動(dong)。(4) 荷電(dian)(dian)粉塵(chen)(chen)(chen)的(de)(de)(de)捕(bu)集。
