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)器是以(yi)靜電(dian)(dian)(dian)凈(jing)化法來收捕(bu)廢氣(qi)(qi)(qi)中的(de)粉塵(chen)(chen)，它的(de)凈(jing)化工作上(shang)要是依靠電(dian)(dian)(dian)暈(yun)(yun)極(ji)和(he)(he)沉淀兩個系(xi)統來完成的(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)進人(ren)(ren)(ren)(ren)氣(qi)(qi)(qi)刺(ci)叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)受到氣(qi)(qi)(qi)流(liu)分布板(ban)以(yi)及折流(liu)板(ban)的(de)調(diao)整后(hou)，使(shi)氣(qi)(qi)(qi)流(liu)能較(jiao)均勻地(di)進人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場。在橫(heng)斷(duan)面(mian)擴大(da)的(de)作用下，氣(qi)(qi)(qi)流(liu)速(su)度迅速(su)降低，其中有些(xie)較(jiao)重的(de)塵(chen)(chen)粒便失去速(su)度而沉降下來。進人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場的(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)由于(yu)電(dian)(dian)(dian)暈(yun)(yun)極(ji)通人(ren)(ren)(ren)(ren)高(gao)壓(ya)直流(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈(yun)(yun)極(ji)附近產生電(dian)(dian)(dian)暈(yun)(yun)現(xian)象，使(shi)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后(hou)的(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)中存在大(da)量(liang)的(de)電(dian)(dian)(dian)子(zi)和(he)(he)離子(zi)，這些(xie)電(dian)(dian)(dian)子(zi)和(he)(he)離子(zi)與(yu)進人(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場的(de)粉塵(chen)(chen)結合起來，使(shi)塵(chen)(chen)粒帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)(dian)場力的(de)作用下趨向(xiang)本(ben)設(she)(she)(she)備(bei)陽(yang)(yang)極(ji)(正極(ji)、本(ben)設(she)(she)(she)備(bei)采用負(fu)高(gao)壓(ya)制)和(he)(he)陰極(ji)(負(fu)極(ji)) ， 釋(shi)放出(chu)電(dian)(dian)(dian)子(zi)分別(bie)沉積在相應的(de)電(dian)(dian)(dian)極(ji)上(shang)，通過設(she)(she)(she)備(bei)陰陽(yang)(yang)極(ji)振打系(xi)統的(de)振打，使(shi)沉積在陰陽(yang)(yang)電(dian)(dian)(dian)極(ji)上(shang)的(de)粉塵(chen)(chen)振落，進人(ren)(ren)(ren)(ren)集灰斗 通過排(pai)灰裝(zhuang)置放出(chu)，回收有物料，被)凈(jing)化的(de)氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)排(pai)入大(da)氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)工作原理是(shi)利用高壓電(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)(dian)(dian)離(li)，氣(qi)流中(zhong)的(de)(de)粉塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)作用下(xia)與氣(qi)流分離(li)。負極(ji)(ji)由(you)不(bu)(bu)同(tong)斷面形狀(zhuang)的(de)(de)金(jin)屬導線制(zhi)成，叫(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由(you)不(bu)(bu)同(tong)幾何(he)形狀(zhuang)的(de)(de)金(jin)屬板制(zhi)成，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)(de)性能受粉塵(chen)(chen)性質、設備構造(zao)和(he)煙氣(qi)流速等三(san)個因素的(de)(de)影響。粉塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)是(shi)評價導電(dian)(dian)(dian)(dian)性的(de)(de)指標，它對(dui)除(chu)塵(chen)(chen)效率(lv)有(you)直接的(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)粒(li)難以保(bao)持在(zai)(zai)集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，致使其(qi)重返氣(qi)流。比(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)過高，到達(da)集塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷(he)不(bu)(bu)易(yi)放出，在(zai)(zai)塵(chen)(chen)層(ceng)之間形成電(dian)(dian)(dian)(dian)壓梯(ti)度會產生局部擊穿和(he)放電(dian)(dian)(dian)(dian)現象。這些情況都(dou)會造(zao)成除(chu)塵(chen)(chen)效率(lv)下(xia)降。

電除塵器的(de)基(ji)本原(yuan)理(li)是利(li)用電力捕集(ji)煙氣(qi)中的(de)粉(fen)塵，主(zhu)要包括以下四個相互有關(guan)的(de)物理(li)過程: (1) 氣(qi)體(ti)(ti)的(de)電離。(2) 粉(fen)塵的(de)荷(he)電。(3) 荷(he)電粉(fen)塵向(xiang)電極移動。(4) 荷(he)電粉(fen)塵的(de)捕集(ji)。
