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(wo)式靜電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是以(yi)(yi)靜電(dian)(dian)(dian)(dian)凈化法來(lai)收捕廢氣(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)(chen)，它(ta)的(de)(de)(de)凈化工作(zuo)上(shang)(shang)要是依靠電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)和(he)沉(chen)淀兩個系(xi)統來(lai)完成的(de)(de)(de)，當(dang)含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)進(jin)人(ren)氣(qi)(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)受到氣(qi)(qi)流分布板以(yi)(yi)及折流板的(de)(de)(de)調(diao)整(zheng)后，使(shi)(shi)氣(qi)(qi)流能較均(jun)勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大(da)的(de)(de)(de)作(zuo)用下，氣(qi)(qi)流速(su)度迅(xun)速(su)降低(di)，其中有(you)些較重的(de)(de)(de)塵(chen)(chen)(chen)粒(li)便(bian)失去速(su)度而(er)沉(chen)降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)通人(ren)高壓直(zhi)流電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)附(fu)近(jin)產生(sheng)電(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)離(li)(li)后的(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)中存在(zai)(zai)大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)(li)子(zi)與進(jin)人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)，使(shi)(shi)塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)用下趨向(xiang)本(ben)設備陽極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本(ben)設備采用負(fu)高壓制(zhi))和(he)陰極(ji)(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)(shang)，通過設備陰陽極(ji)(ji)(ji)(ji)振(zhen)打系(xi)統的(de)(de)(de)振(zhen)打，使(shi)(shi)沉(chen)積在(zai)(zai)陰陽電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)(shang)的(de)(de)(de)粉塵(chen)(chen)(chen)振(zhen)落，進(jin)人(ren)集灰(hui)斗 通過排灰(hui)裝置放(fang)出，回收有(you)物料，被(bei))凈化的(de)(de)(de)氣(qi)(qi)體(ti)(ti)(ti)排入大(da)氣(qi)(qi)。

工作(zuo)原理

靜(jing)電(dian)除(chu)(chu)塵(chen)器的(de)(de)工(gong)作原理是利用(yong)高壓電(dian)場使煙氣(qi)發生(sheng)電(dian)離，氣(qi)流(liu)中(zhong)的(de)(de)粉(fen)塵(chen)荷電(dian)在電(dian)場作用(yong)下(xia)與氣(qi)流(liu)分離。負極(ji)由(you)不(bu)(bu)同(tong)斷(duan)面形狀的(de)(de)金屬(shu)導(dao)(dao)線制成(cheng)(cheng)，叫放電(dian)電(dian)極(ji)。正極(ji)由(you)不(bu)(bu)同(tong)幾何形狀的(de)(de)金屬(shu)板(ban)制成(cheng)(cheng)，叫集塵(chen)電(dian)極(ji)。靜(jing)電(dian)除(chu)(chu)塵(chen)器的(de)(de)性能受粉(fen)塵(chen)性質(zhi)、設備構造和(he)(he)煙氣(qi)流(liu)速等三(san)個因素(su)的(de)(de)影(ying)響。粉(fen)塵(chen)的(de)(de)比(bi)電(dian)阻(zu)是評價導(dao)(dao)電(dian)性的(de)(de)指標，它對除(chu)(chu)塵(chen)效率(lv)有直接的(de)(de)影(ying)響。比(bi)電(dian)阻(zu)過低，塵(chen)粒難以保(bao)持(chi)在集塵(chen)電(dian)極(ji)上，致(zhi)使其(qi)重返氣(qi)流(liu)。比(bi)電(dian)阻(zu)過高，到達集塵(chen)電(dian)極(ji)的(de)(de)塵(chen)粒電(dian)荷不(bu)(bu)易(yi)放出，在塵(chen)層之間形成(cheng)(cheng)電(dian)壓梯(ti)度會產生(sheng)局部擊穿(chuan)和(he)(he)放電(dian)現象。這些情況都會造成(cheng)(cheng)除(chu)(chu)塵(chen)效率(lv)下(xia)降。

電(dian)(dian)除塵(chen)(chen)器的基本原理是利用電(dian)(dian)力捕集(ji)煙(yan)氣中的粉(fen)塵(chen)(chen)，主要包括(kuo)以下(xia)四(si)個(ge)相互有(you)關(guan)的物(wu)理過程(cheng): (1) 氣體(ti)(ti)的電(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)極(ji)移動(dong)。(4) 荷電(dian)(dian)粉(fen)塵(chen)(chen)的捕集(ji)。
