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)除塵(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法(fa)來收捕廢氣(qi)(qi)(qi)中的(de)粉塵(chen)(chen)，它(ta)的(de)凈(jing)化(hua)工作上(shang)要(yao)是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)沉淀兩(liang)個系(xi)統來完成的(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)進(jin)(jin)人(ren)(ren)氣(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)受(shou)到氣(qi)(qi)(qi)流(liu)分(fen)布板(ban)以及折流(liu)板(ban)的(de)調(diao)整后，使(shi)氣(qi)(qi)(qi)流(liu)能較(jiao)均勻地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場。在橫(heng)斷面擴大的(de)作用下，氣(qi)(qi)(qi)流(liu)速度(du)迅速降低，其中有些(xie)較(jiao)重的(de)塵(chen)(chen)粒便失去(qu)速度(du)而沉降下來。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人(ren)(ren)高(gao)(gao)壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)，則(ze)在電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)氣(qi)(qi)(qi)體(ti)中存在大量的(de)電(dian)(dian)(dian)(dian)(dian)子和(he)離子，這(zhe)些(xie)電(dian)(dian)(dian)(dian)(dian)子和(he)離子與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)粉塵(chen)(chen)結合起來，使(shi)塵(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)(dian)(dian)(dian)場力的(de)作用下趨(qu)向(xiang)本設備陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備采用負(fu)高(gao)(gao)壓(ya)制)和(he)陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子分(fen)別沉積在相應的(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通過設備陰(yin)陽極(ji)(ji)(ji)振(zhen)打(da)(da)系(xi)統的(de)振(zhen)打(da)(da)，使(shi)沉積在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)粉塵(chen)(chen)振(zhen)落(luo)，進(jin)(jin)人(ren)(ren)集(ji)灰斗 通過排灰裝置放出，回收有物料(liao)，被)凈(jing)化(hua)的(de)氣(qi)(qi)(qi)體(ti)排入大氣(qi)(qi)(qi)。

工(gong)作原理

靜電除塵(chen)(chen)(chen)(chen)器的(de)(de)工作原理是利用(yong)高(gao)壓電場使煙(yan)氣(qi)發生電離，氣(qi)流中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電在電場作用(yong)下(xia)與氣(qi)流分離。負(fu)極(ji)由不(bu)同斷面形狀的(de)(de)金(jin)屬導線制成(cheng)，叫(jiao)放(fang)電電極(ji)。正(zheng)極(ji)由不(bu)同幾何形狀的(de)(de)金(jin)屬板制成(cheng)，叫(jiao)集塵(chen)(chen)(chen)(chen)電極(ji)。靜電除塵(chen)(chen)(chen)(chen)器的(de)(de)性能受粉(fen)塵(chen)(chen)(chen)(chen)性質、設備構造(zao)和煙(yan)氣(qi)流速等三個因素的(de)(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)比(bi)電阻(zu)是評價導電性的(de)(de)指標，它對(dui)除塵(chen)(chen)(chen)(chen)效率(lv)有直接的(de)(de)影(ying)響。比(bi)電阻(zu)過(guo)低，塵(chen)(chen)(chen)(chen)粒難以保(bao)持在集塵(chen)(chen)(chen)(chen)電極(ji)上，致使其重(zhong)返氣(qi)流。比(bi)電阻(zu)過(guo)高(gao)，到達集塵(chen)(chen)(chen)(chen)電極(ji)的(de)(de)塵(chen)(chen)(chen)(chen)粒電荷(he)不(bu)易(yi)放(fang)出，在塵(chen)(chen)(chen)(chen)層之間形成(cheng)電壓梯度會產生局部擊(ji)穿和放(fang)電現象。這些情況都會造(zao)成(cheng)除塵(chen)(chen)(chen)(chen)效率(lv)下(xia)降。

電(dian)(dian)除塵器的(de)基本原理(li)是利(li)用(yong)電(dian)(dian)力捕(bu)集(ji)煙氣(qi)(qi)中(zhong)的(de)粉(fen)塵，主要包括以下四個相互有關的(de)物理(li)過程: (1) 氣(qi)(qi)體(ti)的(de)電(dian)(dian)離(li)。(2) 粉(fen)塵的(de)荷(he)(he)電(dian)(dian)。(3) 荷(he)(he)電(dian)(dian)粉(fen)塵向電(dian)(dian)極(ji)移(yi)動。(4) 荷(he)(he)電(dian)(dian)粉(fen)塵的(de)捕(bu)集(ji)。
