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)除塵(chen)(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)凈化(hua)法來(lai)收(shou)捕廢(fei)氣(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)凈化(hua)工作上(shang)要是(shi)依(yi)靠電(dian)(dian)(dian)暈極和(he)沉(chen)(chen)淀兩個系(xi)統(tong)來(lai)完成的(de)(de)(de)，當(dang)含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進人(ren)氣(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受到(dao)氣(qi)(qi)流分布板以及折流板的(de)(de)(de)調整后，使(shi)(shi)氣(qi)(qi)流能較均(jun)勻地進人(ren)電(dian)(dian)(dian)場(chang)。在(zai)(zai)(zai)橫(heng)斷面擴大(da)的(de)(de)(de)作用(yong)下(xia)，氣(qi)(qi)流速(su)度(du)迅速(su)降低，其中有些較重(zhong)的(de)(de)(de)塵(chen)(chen)(chen)粒(li)便(bian)失(shi)去速(su)度(du)而沉(chen)(chen)降下(xia)來(lai)。進人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)暈極通人(ren)高(gao)(gao)壓直流電(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)暈極附近產生(sheng)電(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)(qi)體(ti)(ti)中存在(zai)(zai)(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)子和(he)離子，這(zhe)些電(dian)(dian)(dian)子和(he)離子與進人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)，使(shi)(shi)塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)(zai)(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用(yong)下(xia)趨(qu)向本設備陽極(正極、本設備采用(yong)負高(gao)(gao)壓制(zhi))和(he)陰(yin)(yin)極(負極) ， 釋放(fang)出電(dian)(dian)(dian)子分別沉(chen)(chen)積(ji)在(zai)(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)極上(shang)，通過設備陰(yin)(yin)陽極振(zhen)(zhen)打(da)系(xi)統(tong)的(de)(de)(de)振(zhen)(zhen)打(da)，使(shi)(shi)沉(chen)(chen)積(ji)在(zai)(zai)(zai)陰(yin)(yin)陽電(dian)(dian)(dian)極上(shang)的(de)(de)(de)粉塵(chen)(chen)(chen)振(zhen)(zhen)落，進人(ren)集(ji)灰斗 通過排灰裝置放(fang)出，回收(shou)有物料，被)凈化(hua)的(de)(de)(de)氣(qi)(qi)體(ti)(ti)排入大(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)除塵(chen)(chen)器的(de)(de)工作原理是(shi)利用(yong)高(gao)壓電(dian)(dian)場(chang)使(shi)煙氣(qi)發(fa)生電(dian)(dian)離，氣(qi)流中的(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場(chang)作用(yong)下與氣(qi)流分離。負(fu)極(ji)(ji)由(you)不同斷面形狀的(de)(de)金屬導(dao)線制(zhi)成(cheng)，叫放電(dian)(dian)電(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不同幾何(he)形狀的(de)(de)金屬板制(zhi)成(cheng)，叫集塵(chen)(chen)電(dian)(dian)極(ji)(ji)。靜電(dian)(dian)除塵(chen)(chen)器的(de)(de)性(xing)能受粉(fen)塵(chen)(chen)性(xing)質、設(she)備構造(zao)和煙氣(qi)流速等三個因素的(de)(de)影響(xiang)(xiang)。粉(fen)塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)阻是(shi)評價導(dao)電(dian)(dian)性(xing)的(de)(de)指標，它對除塵(chen)(chen)效(xiao)率有(you)直接的(de)(de)影響(xiang)(xiang)。比(bi)電(dian)(dian)阻過(guo)低，塵(chen)(chen)粒難(nan)以保(bao)持在(zai)集塵(chen)(chen)電(dian)(dian)極(ji)(ji)上，致使(shi)其重返(fan)氣(qi)流。比(bi)電(dian)(dian)阻過(guo)高(gao)，到達集塵(chen)(chen)電(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)荷不易放出，在(zai)塵(chen)(chen)層之(zhi)間形成(cheng)電(dian)(dian)壓梯度(du)會產生局部擊穿和放電(dian)(dian)現象。這些情況都會造(zao)成(cheng)除塵(chen)(chen)效(xiao)率下降。

電(dian)除塵器的基本原理(li)是利(li)用(yong)電(dian)力捕(bu)集(ji)煙氣中的粉塵，主要包(bao)括(kuo)以下四個相互有(you)關的物理(li)過程: (1) 氣體的電(dian)離。(2) 粉塵的荷電(dian)。(3) 荷電(dian)粉塵向電(dian)極移動。(4) 荷電(dian)粉塵的捕(bu)集(ji)。
