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)器是以靜電(dian)(dian)(dian)凈化(hua)法來收捕廢氣(qi)中的(de)(de)(de)粉塵(chen)，它的(de)(de)(de)凈化(hua)工作(zuo)上(shang)(shang)要是依靠電(dian)(dian)(dian)暈(yun)極(ji)和(he)沉淀兩個系(xi)統(tong)來完成(cheng)的(de)(de)(de)，當含塵(chen)氣(qi)體(ti)(ti)進(jin)(jin)人(ren)(ren)氣(qi)刺叭(ba)時，含塵(chen)氣(qi)體(ti)(ti)受到氣(qi)流分布(bu)板以及折(zhe)流板的(de)(de)(de)調整后，使(shi)(shi)氣(qi)流能較(jiao)均(jun)勻地(di)進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)場。在(zai)(zai)(zai)(zai)橫斷面(mian)擴大(da)的(de)(de)(de)作(zuo)用(yong)(yong)下(xia)，氣(qi)流速(su)度迅速(su)降(jiang)(jiang)低，其中有些較(jiao)重的(de)(de)(de)塵(chen)粒(li)(li)便(bian)失(shi)去速(su)度而沉降(jiang)(jiang)下(xia)來。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)氣(qi)體(ti)(ti)由于電(dian)(dian)(dian)暈(yun)極(ji)通人(ren)(ren)高壓直流電(dian)(dian)(dian)，則(ze)在(zai)(zai)(zai)(zai)電(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)暈(yun)現象，使(shi)(shi)氣(qi)體(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)氣(qi)體(ti)(ti)中存在(zai)(zai)(zai)(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)子(zi)和(he)離子(zi)，這些電(dian)(dian)(dian)子(zi)和(he)離子(zi)與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)結合起來，使(shi)(shi)塵(chen)粒(li)(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒(li)(li)在(zai)(zai)(zai)(zai)電(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)用(yong)(yong)下(xia)趨(qu)向(xiang)本設(she)備(bei)陽(yang)極(ji)(正極(ji)、本設(she)備(bei)采用(yong)(yong)負高壓制(zhi))和(he)陰極(ji)(負極(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)子(zi)分別沉積在(zai)(zai)(zai)(zai)相(xiang)應(ying)的(de)(de)(de)電(dian)(dian)(dian)極(ji)上(shang)(shang)，通過設(she)備(bei)陰陽(yang)極(ji)振打系(xi)統(tong)的(de)(de)(de)振打，使(shi)(shi)沉積在(zai)(zai)(zai)(zai)陰陽(yang)電(dian)(dian)(dian)極(ji)上(shang)(shang)的(de)(de)(de)粉塵(chen)振落，進(jin)(jin)人(ren)(ren)集灰(hui)(hui)斗 通過排(pai)(pai)灰(hui)(hui)裝(zhuang)置(zhi)放(fang)出(chu)，回收有物料，被)凈化(hua)的(de)(de)(de)氣(qi)體(ti)(ti)排(pai)(pai)入(ru)大(da)氣(qi)。

工作(zuo)原理

靜(jing)(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)工作原理是利(li)用高壓電(dian)(dian)(dian)(dian)場使煙(yan)氣發生電(dian)(dian)(dian)(dian)離(li)，氣流(liu)中的(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作用下(xia)與(yu)氣流(liu)分離(li)。負極由不(bu)(bu)(bu)同斷面形狀(zhuang)的(de)金屬(shu)導線制成(cheng)(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正(zheng)極由不(bu)(bu)(bu)同幾何形狀(zhuang)的(de)金屬(shu)板制成(cheng)(cheng)，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜(jing)(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)性能受粉(fen)塵(chen)(chen)(chen)(chen)性質、設備(bei)構造和煙(yan)氣流(liu)速等三(san)個因素(su)的(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)性的(de)指標，它對除塵(chen)(chen)(chen)(chen)效率有(you)直接的(de)影響(xiang)。比電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)粒(li)難(nan)以保(bao)持在(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上，致使其重返(fan)氣流(liu)。比電(dian)(dian)(dian)(dian)阻(zu)過高，到(dao)達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不(bu)(bu)(bu)易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)層之間形成(cheng)(cheng)電(dian)(dian)(dian)(dian)壓梯度(du)會(hui)產生局部擊(ji)穿和放(fang)電(dian)(dian)(dian)(dian)現象。這些情況都(dou)會(hui)造成(cheng)(cheng)除塵(chen)(chen)(chen)(chen)效率下(xia)降。

電除(chu)塵器的(de)(de)(de)基本原理是利(li)用(yong)電力捕集(ji)煙氣中的(de)(de)(de)粉塵，主要包括以下四個相互有關的(de)(de)(de)物理過程: (1) 氣體的(de)(de)(de)電離。(2) 粉塵的(de)(de)(de)荷(he)電。(3) 荷(he)電粉塵向(xiang)電極移(yi)動。(4) 荷(he)電粉塵的(de)(de)(de)捕集(ji)。
