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)除塵器是以靜(jing)電(dian)(dian)(dian)(dian)凈化法來(lai)(lai)收捕(bu)廢氣(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)粉(fen)(fen)塵，它(ta)的(de)(de)(de)(de)(de)凈化工(gong)作(zuo)上要是依靠(kao)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)沉(chen)(chen)淀兩(liang)個系(xi)統來(lai)(lai)完(wan)成的(de)(de)(de)(de)(de)，當(dang)含塵氣(qi)(qi)體進人(ren)(ren)氣(qi)(qi)刺叭時，含塵氣(qi)(qi)體受到氣(qi)(qi)流分(fen)布板(ban)(ban)以及折(zhe)流板(ban)(ban)的(de)(de)(de)(de)(de)調(diao)整(zheng)后，使氣(qi)(qi)流能較(jiao)均勻地進人(ren)(ren)電(dian)(dian)(dian)(dian)場。在橫斷面擴(kuo)大(da)的(de)(de)(de)(de)(de)作(zuo)用(yong)下，氣(qi)(qi)流速度(du)迅速降低，其(qi)中(zhong)有些較(jiao)重的(de)(de)(de)(de)(de)塵粒(li)便(bian)失去速度(du)而沉(chen)(chen)降下來(lai)(lai)。進人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)含塵氣(qi)(qi)體由(you)于(yu)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通人(ren)(ren)高壓直流電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)體電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)(de)氣(qi)(qi)體中(zhong)存在大(da)量(liang)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進人(ren)(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)粉(fen)(fen)塵結(jie)合(he)起來(lai)(lai)，使塵粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵粒(li)在電(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)作(zuo)用(yong)下趨向(xiang)本設備(bei)陽(yang)極(ji)(ji)(正極(ji)(ji)、本設備(bei)采用(yong)負高壓制)和(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)(chen)積在相應(ying)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上，通過設備(bei)陰陽(yang)極(ji)(ji)振打系(xi)統的(de)(de)(de)(de)(de)振打，使沉(chen)(chen)積在陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)(de)粉(fen)(fen)塵振落(luo)，進人(ren)(ren)集灰斗 通過排灰裝置放(fang)出，回(hui)收有物料，被)凈化的(de)(de)(de)(de)(de)氣(qi)(qi)體排入大(da)氣(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)工作(zuo)原理是(shi)利用高壓(ya)電(dian)(dian)(dian)場(chang)使(shi)(shi)煙氣發生(sheng)電(dian)(dian)(dian)離，氣流中的(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作(zuo)用下與(yu)氣流分離。負極(ji)(ji)(ji)由不(bu)(bu)同(tong)斷(duan)面形(xing)狀(zhuang)的(de)金屬導線制成(cheng)，叫放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不(bu)(bu)同(tong)幾何(he)形(xing)狀(zhuang)的(de)金屬板制成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)性能受粉(fen)塵(chen)(chen)(chen)性質、設(she)備構造和(he)煙氣流速等三(san)個因素的(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)阻(zu)是(shi)評價(jia)導電(dian)(dian)(dian)性的(de)指標，它對除塵(chen)(chen)(chen)效(xiao)率(lv)有直(zhi)接的(de)影(ying)響。比電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒(li)難以保持在集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)上，致(zhi)使(shi)(shi)其重返氣流。比電(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)(ji)的(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)荷不(bu)(bu)易放(fang)(fang)出，在塵(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)壓(ya)梯度會產生(sheng)局(ju)部(bu)擊穿和(he)放(fang)(fang)電(dian)(dian)(dian)現象(xiang)。這些情(qing)況都會造成(cheng)除塵(chen)(chen)(chen)效(xiao)率(lv)下降。

電(dian)(dian)(dian)除塵(chen)器的(de)基本(ben)原理是利用電(dian)(dian)(dian)力捕集煙氣中的(de)粉塵(chen)，主要包(bao)括以下四(si)個相互有關(guan)的(de)物理過程: (1) 氣體的(de)電(dian)(dian)(dian)離。(2) 粉塵(chen)的(de)荷電(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)粉塵(chen)向電(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)粉塵(chen)的(de)捕集。
