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(shi)靜(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈化法來收捕廢(fei)氣(qi)(qi)(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)凈化工作(zuo)上(shang)要是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)(he)沉淀兩個系統(tong)來完(wan)成的(de)(de)(de)，當(dang)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)進(jin)人氣(qi)(qi)(qi)(qi)刺(ci)叭(ba)時，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)受到氣(qi)(qi)(qi)(qi)流分布板(ban)以及折(zhe)流板(ban)的(de)(de)(de)調整后，使(shi)(shi)(shi)氣(qi)(qi)(qi)(qi)流能較(jiao)均勻地進(jin)人電(dian)(dian)(dian)(dian)(dian)場。在(zai)橫(heng)斷面(mian)擴大(da)的(de)(de)(de)作(zuo)用(yong)下(xia)，氣(qi)(qi)(qi)(qi)流速(su)(su)度(du)迅速(su)(su)降低，其中有些較(jiao)重的(de)(de)(de)塵(chen)(chen)(chen)粒(li)便失去速(su)(su)度(du)而沉降下(xia)來。進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)人高壓直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)(shi)(shi)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)中存(cun)在(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)(he)離(li)(li)子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)(he)離(li)(li)子(zi)與進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)(chen)(chen)結(jie)合(he)起來，使(shi)(shi)(shi)塵(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)用(yong)下(xia)趨向(xiang)本(ben)設(she)備陽極(ji)(ji)(正極(ji)(ji)、本(ben)設(she)備采(cai)用(yong)負(fu)高壓制)和(he)(he)陰(yin)(yin)極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)分別沉積在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通(tong)過設(she)備陰(yin)(yin)陽極(ji)(ji)振打系統(tong)的(de)(de)(de)振打，使(shi)(shi)(shi)沉積在(zai)陰(yin)(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)粉塵(chen)(chen)(chen)振落，進(jin)人集灰斗 通(tong)過排(pai)灰裝置放出，回收有物料，被)凈化的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)排(pai)入大(da)氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)(de)工作原理是利用高壓電(dian)(dian)(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流(liu)(liu)中的(de)(de)粉塵(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作用下與氣(qi)流(liu)(liu)分離。負極(ji)(ji)由不(bu)同(tong)斷面形(xing)狀的(de)(de)金屬(shu)(shu)導(dao)(dao)線制成(cheng)(cheng)，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同(tong)幾(ji)何形(xing)狀的(de)(de)金屬(shu)(shu)板(ban)制成(cheng)(cheng)，叫(jiao)集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)(de)性能(neng)受(shou)粉塵(chen)性質、設備構造(zao)和煙氣(qi)流(liu)(liu)速等三個(ge)因素的(de)(de)影響(xiang)。粉塵(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價(jia)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)性的(de)(de)指標(biao)，它(ta)對除(chu)塵(chen)效率(lv)有(you)直接的(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)粒(li)(li)難以保(bao)持在集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其(qi)重返(fan)氣(qi)流(liu)(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到達(da)集塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)粒(li)(li)電(dian)(dian)(dian)(dian)(dian)荷不(bu)易(yi)放出，在塵(chen)層(ceng)之(zhi)間形(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產生局部擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造(zao)成(cheng)(cheng)除(chu)塵(chen)效率(lv)下降(jiang)。

電除塵(chen)器的(de)(de)基本原理是利用電力捕集(ji)煙(yan)氣中的(de)(de)粉(fen)塵(chen)，主要包括以下四(si)個(ge)相(xiang)互有關的(de)(de)物理過程: (1) 氣體(ti)(ti)的(de)(de)電離(li)。(2) 粉(fen)塵(chen)的(de)(de)荷電。(3) 荷電粉(fen)塵(chen)向電極移動。(4) 荷電粉(fen)塵(chen)的(de)(de)捕集(ji)。
