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)除塵(chen)(chen)器(qi)是以(yi)靜電(dian)凈(jing)化(hua)法來(lai)(lai)收(shou)捕廢氣(qi)(qi)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)，它的(de)(de)凈(jing)化(hua)工作上要是依(yi)靠電(dian)暈極(ji)(ji)(ji)(ji)和(he)沉淀兩(liang)個系統來(lai)(lai)完成(cheng)的(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體進人(ren)(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)體受(shou)到氣(qi)(qi)流(liu)分布板(ban)以(yi)及折流(liu)板(ban)的(de)(de)調整后，使氣(qi)(qi)流(liu)能較均勻地進人(ren)(ren)電(dian)場。在(zai)橫斷面擴(kuo)大的(de)(de)作用(yong)(yong)下(xia)，氣(qi)(qi)流(liu)速(su)度迅速(su)降低(di)，其中(zhong)有些較重的(de)(de)塵(chen)(chen)粒便失去速(su)度而沉降下(xia)來(lai)(lai)。進人(ren)(ren)電(dian)場的(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體由(you)于電(dian)暈極(ji)(ji)(ji)(ji)通人(ren)(ren)高(gao)(gao)壓(ya)直流(liu)電(dian)，則在(zai)電(dian)暈極(ji)(ji)(ji)(ji)附近(jin)產生電(dian)暈現象(xiang)，使氣(qi)(qi)體電(dian)離，電(dian)離后的(de)(de)氣(qi)(qi)體中(zhong)存在(zai)大量的(de)(de)電(dian)子和(he)離子，這些電(dian)子和(he)離子與進人(ren)(ren)電(dian)場的(de)(de)粉(fen)塵(chen)(chen)結合起來(lai)(lai)，使塵(chen)(chen)粒帶(dai)電(dian)，帶(dai)電(dian)塵(chen)(chen)粒在(zai)電(dian)場力的(de)(de)作用(yong)(yong)下(xia)趨向本設(she)備陽極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設(she)備采用(yong)(yong)負高(gao)(gao)壓(ya)制)和(he)陰(yin)(yin)極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放(fang)出電(dian)子分別沉積(ji)在(zai)相應的(de)(de)電(dian)極(ji)(ji)(ji)(ji)上，通過設(she)備陰(yin)(yin)陽極(ji)(ji)(ji)(ji)振打(da)系統的(de)(de)振打(da)，使沉積(ji)在(zai)陰(yin)(yin)陽電(dian)極(ji)(ji)(ji)(ji)上的(de)(de)粉(fen)塵(chen)(chen)振落，進人(ren)(ren)集灰斗(dou) 通過排灰裝置放(fang)出，回收(shou)有物料，被)凈(jing)化(hua)的(de)(de)氣(qi)(qi)體排入大氣(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)工(gong)作(zuo)原理是(shi)利(li)用高(gao)壓電(dian)(dian)(dian)(dian)(dian)場使煙(yan)(yan)氣(qi)(qi)發生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)(qi)流(liu)(liu)中(zhong)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作(zuo)用下與氣(qi)(qi)流(liu)(liu)分離。負極由(you)不同斷(duan)面(mian)形狀(zhuang)(zhuang)的(de)(de)(de)(de)金屬(shu)導(dao)線(xian)制成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由(you)不同幾(ji)何(he)形狀(zhuang)(zhuang)的(de)(de)(de)(de)金屬(shu)板制成(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質(zhi)、設備構造(zao)和煙(yan)(yan)氣(qi)(qi)流(liu)(liu)速等(deng)三個因素的(de)(de)(de)(de)影(ying)(ying)響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評價導(dao)電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)指標，它對除塵(chen)(chen)(chen)(chen)效率有(you)直(zhi)接的(de)(de)(de)(de)影(ying)(ying)響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)低(di)，塵(chen)(chen)(chen)(chen)粒(li)難(nan)以保持在集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使其(qi)重返氣(qi)(qi)流(liu)(liu)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)高(gao)，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷(he)不易放(fang)出，在塵(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯(ti)度會產生局部擊(ji)穿和放(fang)電(dian)(dian)(dian)(dian)(dian)現象。這些情(qing)況都會造(zao)成(cheng)除塵(chen)(chen)(chen)(chen)效率下降(jiang)。

電(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)基本原理(li)(li)是利(li)用電(dian)(dian)(dian)(dian)力(li)捕集煙氣中的(de)(de)粉塵(chen)，主要包括以下四個相互(hu)有關的(de)(de)物理(li)(li)過程(cheng): (1) 氣體的(de)(de)電(dian)(dian)(dian)(dian)離(li)。(2) 粉塵(chen)的(de)(de)荷(he)電(dian)(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)(dian)粉塵(chen)向電(dian)(dian)(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)(dian)(dian)粉塵(chen)的(de)(de)捕集。
