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(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)器是以靜(jing)電(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收捕廢氣(qi)(qi)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)，它(ta)的(de)(de)凈(jing)化(hua)工作(zuo)上(shang)要是依靠電(dian)(dian)(dian)暈(yun)(yun)極和(he)沉(chen)(chen)淀兩(liang)個系統來(lai)完(wan)成的(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進人(ren)(ren)(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流分(fen)布板(ban)以及折流板(ban)的(de)(de)調(diao)整(zheng)后(hou)，使氣(qi)(qi)流能較均勻地進人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)(de)作(zuo)用(yong)(yong)下，氣(qi)(qi)流速(su)度(du)(du)迅速(su)降低，其中(zhong)有(you)些較重的(de)(de)塵(chen)(chen)(chen)粒(li)便失去(qu)速(su)度(du)(du)而(er)沉(chen)(chen)降下來(lai)。進人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由(you)于電(dian)(dian)(dian)暈(yun)(yun)極通(tong)人(ren)(ren)(ren)高壓(ya)直流電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)(yun)極附近產生(sheng)電(dian)(dian)(dian)暈(yun)(yun)現象，使氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后(hou)的(de)(de)氣(qi)(qi)體(ti)(ti)中(zhong)存在(zai)大(da)量的(de)(de)電(dian)(dian)(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)，這(zhe)些電(dian)(dian)(dian)子(zi)(zi)和(he)離(li)子(zi)(zi)與進人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)(chen)(chen)結(jie)合(he)起來(lai)，使塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用(yong)(yong)下趨向本(ben)設(she)備陽(yang)極(正極、本(ben)設(she)備采(cai)用(yong)(yong)負高壓(ya)制)和(he)陰(yin)極(負極) ， 釋放出電(dian)(dian)(dian)子(zi)(zi)分(fen)別沉(chen)(chen)積在(zai)相(xiang)應的(de)(de)電(dian)(dian)(dian)極上(shang)，通(tong)過(guo)設(she)備陰(yin)陽(yang)極振打系統的(de)(de)振打，使沉(chen)(chen)積在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)極上(shang)的(de)(de)粉(fen)塵(chen)(chen)(chen)振落，進人(ren)(ren)(ren)集(ji)灰斗 通(tong)過(guo)排灰裝置(zhi)放出，回(hui)收有(you)物(wu)料，被)凈(jing)化(hua)的(de)(de)氣(qi)(qi)體(ti)(ti)排入(ru)大(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)工(gong)作原(yuan)理(li)是利(li)用高壓(ya)電(dian)(dian)(dian)場(chang)使煙氣(qi)(qi)發生電(dian)(dian)(dian)離(li)，氣(qi)(qi)流中的(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作用下(xia)(xia)與氣(qi)(qi)流分離(li)。負極由(you)不(bu)同(tong)斷面(mian)形狀的(de)金(jin)屬導(dao)線制(zhi)成(cheng)(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由(you)不(bu)同(tong)幾何形狀的(de)金(jin)屬板制(zhi)成(cheng)(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)性(xing)能受粉(fen)塵(chen)(chen)性(xing)質、設備構造(zao)和煙氣(qi)(qi)流速(su)等三個因素的(de)影(ying)(ying)響(xiang)。粉(fen)塵(chen)(chen)的(de)比(bi)(bi)電(dian)(dian)(dian)阻(zu)是評價導(dao)電(dian)(dian)(dian)性(xing)的(de)指標，它對除(chu)(chu)塵(chen)(chen)效率(lv)有直接的(de)影(ying)(ying)響(xiang)。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)粒難以保持在集塵(chen)(chen)電(dian)(dian)(dian)極上，致使其重(zhong)返(fan)氣(qi)(qi)流。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)高，到達集塵(chen)(chen)電(dian)(dian)(dian)極的(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易(yi)放出(chu)，在塵(chen)(chen)層之間(jian)形成(cheng)(cheng)電(dian)(dian)(dian)壓(ya)梯度會產生局(ju)部擊穿(chuan)和放電(dian)(dian)(dian)現(xian)象。這些情況都會造(zao)成(cheng)(cheng)除(chu)(chu)塵(chen)(chen)效率(lv)下(xia)(xia)降。

電(dian)除塵(chen)器的(de)(de)基(ji)本原理(li)是利用電(dian)力捕(bu)(bu)集煙氣(qi)中的(de)(de)粉(fen)塵(chen)，主要(yao)包括以下四個相互有關的(de)(de)物理(li)過(guo)程: (1) 氣(qi)體(ti)的(de)(de)電(dian)離。(2) 粉(fen)塵(chen)的(de)(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵(chen)向(xiang)電(dian)極移動。(4) 荷(he)電(dian)粉(fen)塵(chen)的(de)(de)捕(bu)(bu)集。
