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)(dian)(dian)除塵(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法(fa)來收(shou)捕廢氣(qi)(qi)(qi)中(zhong)(zhong)的(de)(de)(de)(de)粉塵(chen)(chen)，它(ta)的(de)(de)(de)(de)凈(jing)化(hua)工(gong)作(zuo)(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)和(he)沉(chen)淀兩(liang)個(ge)系統(tong)來完成的(de)(de)(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進(jin)人氣(qi)(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受(shou)到氣(qi)(qi)(qi)流(liu)分(fen)布板(ban)以(yi)及折流(liu)板(ban)的(de)(de)(de)(de)調(diao)整后，使(shi)氣(qi)(qi)(qi)流(liu)能較均勻地進(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)(zai)橫(heng)斷面擴大的(de)(de)(de)(de)作(zuo)(zuo)用(yong)下(xia)，氣(qi)(qi)(qi)流(liu)速(su)度(du)迅速(su)降低，其中(zhong)(zhong)有(you)些較重的(de)(de)(de)(de)塵(chen)(chen)粒便失(shi)去速(su)度(du)而沉(chen)降下(xia)來。進(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)通(tong)人高(gao)壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)附近(jin)產生(sheng)電(dian)(dian)(dian)(dian)(dian)暈現(xian)象(xiang)，使(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中(zhong)(zhong)存在(zai)(zai)(zai)大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)與(yu)進(jin)人電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)粉塵(chen)(chen)結合起來，使(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)作(zuo)(zuo)用(yong)下(xia)趨向本設(she)備(bei)(bei)陽極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設(she)備(bei)(bei)采(cai)用(yong)負高(gao)壓(ya)制)和(he)陰極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分(fen)別(bie)沉(chen)積(ji)在(zai)(zai)(zai)相應(ying)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，通(tong)過設(she)備(bei)(bei)陰陽極(ji)(ji)(ji)(ji)振(zhen)打(da)系統(tong)的(de)(de)(de)(de)振(zhen)打(da)，使(shi)沉(chen)積(ji)在(zai)(zai)(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上的(de)(de)(de)(de)粉塵(chen)(chen)振(zhen)落，進(jin)人集灰(hui)斗 通(tong)過排(pai)灰(hui)裝置放出，回收(shou)有(you)物料，被)凈(jing)化(hua)的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排(pai)入大氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)的(de)(de)(de)(de)工作(zuo)原理是(shi)利用高(gao)(gao)壓電(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)(qi)發(fa)生電(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)(qi)流中的(de)(de)(de)(de)粉(fen)(fen)塵(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作(zuo)用下(xia)與氣(qi)(qi)(qi)流分離(li)。負極(ji)由(you)不同斷面形狀的(de)(de)(de)(de)金屬(shu)導線制成(cheng)(cheng)(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同幾何形狀的(de)(de)(de)(de)金屬(shu)板制成(cheng)(cheng)(cheng)，叫集塵(chen)電(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)的(de)(de)(de)(de)性能受粉(fen)(fen)塵(chen)性質、設備構造(zao)和煙氣(qi)(qi)(qi)流速等三個(ge)因素的(de)(de)(de)(de)影響。粉(fen)(fen)塵(chen)的(de)(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)(dian)性的(de)(de)(de)(de)指(zhi)標，它(ta)對(dui)除(chu)(chu)(chu)塵(chen)效率有直接的(de)(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)粒(li)(li)難以保持在(zai)集塵(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其重返(fan)氣(qi)(qi)(qi)流。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過高(gao)(gao)，到達(da)集塵(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)粒(li)(li)電(dian)(dian)(dian)(dian)荷(he)不易(yi)放(fang)出，在(zai)塵(chen)層之間形成(cheng)(cheng)(cheng)電(dian)(dian)(dian)(dian)壓梯度會(hui)產生局部擊穿和放(fang)電(dian)(dian)(dian)(dian)現象。這些情況都會(hui)造(zao)成(cheng)(cheng)(cheng)除(chu)(chu)(chu)塵(chen)效率下(xia)降(jiang)。

電(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)(de)基本(ben)原(yuan)理是利用電(dian)(dian)(dian)(dian)力捕(bu)(bu)集煙氣(qi)中的(de)(de)(de)粉(fen)塵(chen)，主要包括以下四個相互有(you)關(guan)的(de)(de)(de)物理過程: (1) 氣(qi)體的(de)(de)(de)電(dian)(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)(de)(de)荷電(dian)(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)(dian)粉(fen)塵(chen)的(de)(de)(de)捕(bu)(bu)集。
