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(jing)(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)器(qi)是以(yi)靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)凈化法來收捕廢(fei)氣(qi)(qi)中的(de)粉塵(chen)，它的(de)凈化工作上要是依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)沉(chen)(chen)淀(dian)兩個系統來完成的(de)，當含(han)塵(chen)氣(qi)(qi)體進(jin)(jin)人(ren)(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)分布板以(yi)及折流(liu)板的(de)調整后，使(shi)(shi)(shi)氣(qi)(qi)流(liu)能較(jiao)均勻(yun)地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫(heng)斷面擴大的(de)作用(yong)下，氣(qi)(qi)流(liu)速(su)度迅(xun)速(su)降低，其中有(you)些較(jiao)重的(de)塵(chen)粒便失去速(su)度而沉(chen)(chen)降下來。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)含(han)塵(chen)氣(qi)(qi)體由(you)于(yu)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通人(ren)(ren)高(gao)壓直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈現象(xiang)，使(shi)(shi)(shi)氣(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離(li)(li)(li)，電(dian)(dian)(dian)(dian)(dian)離(li)(li)(li)后的(de)氣(qi)(qi)體中存在(zai)(zai)大量(liang)的(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)(li)(li)子(zi)(zi)與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)粉塵(chen)結合起來，使(shi)(shi)(shi)塵(chen)粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)作用(yong)下趨(qu)向(xiang)本設備陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備采用(yong)負高(gao)壓制)和(he)陰(yin)極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別沉(chen)(chen)積(ji)在(zai)(zai)相(xiang)應(ying)的(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通過(guo)設備陰(yin)陽極(ji)(ji)(ji)振打系統的(de)振打，使(shi)(shi)(shi)沉(chen)(chen)積(ji)在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)粉塵(chen)振落，進(jin)(jin)人(ren)(ren)集灰(hui)斗 通過(guo)排(pai)灰(hui)裝(zhuang)置(zhi)放(fang)出，回收有(you)物(wu)料，被)凈化的(de)氣(qi)(qi)體排(pai)入(ru)大氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)(de)(de)工作(zuo)原理是利用高壓電(dian)(dian)(dian)場(chang)使(shi)煙氣發生(sheng)電(dian)(dian)(dian)離(li)，氣流(liu)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)作(zuo)用下(xia)與(yu)氣流(liu)分離(li)。負極由(you)不(bu)(bu)同斷面形狀的(de)(de)(de)(de)金(jin)屬(shu)導(dao)線制(zhi)成(cheng)(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正(zheng)極由(you)不(bu)(bu)同幾何形狀的(de)(de)(de)(de)金(jin)屬(shu)板制(zhi)成(cheng)(cheng)，叫集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)(de)(de)性(xing)能受粉塵(chen)(chen)(chen)性(xing)質、設備構造和(he)煙氣流(liu)速等三個因素(su)的(de)(de)(de)(de)影(ying)響(xiang)。粉塵(chen)(chen)(chen)的(de)(de)(de)(de)比電(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)效率有直(zhi)接的(de)(de)(de)(de)影(ying)響(xiang)。比電(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)粒難以保(bao)持在(zai)集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極上(shang)，致使(shi)其重返氣流(liu)。比電(dian)(dian)(dian)阻過高，到達集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)(bu)易放(fang)出，在(zai)塵(chen)(chen)(chen)層之間形成(cheng)(cheng)電(dian)(dian)(dian)壓梯(ti)度會產生(sheng)局(ju)部擊穿和(he)放(fang)電(dian)(dian)(dian)現象。這些(xie)情況都會造成(cheng)(cheng)除(chu)塵(chen)(chen)(chen)效率下(xia)降(jiang)。

電(dian)(dian)除塵(chen)(chen)器的(de)基本(ben)原(yuan)理是利用電(dian)(dian)力捕集煙氣(qi)中的(de)粉(fen)塵(chen)(chen)，主要(yao)包括以下四(si)個相互有關的(de)物理過程: (1) 氣(qi)體的(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉(fen)塵(chen)(chen)的(de)捕集。
