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)(dian)(dian)除塵(chen)(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)(dian)(dian)凈化法來(lai)(lai)收捕廢氣(qi)(qi)(qi)(qi)(qi)中(zhong)的粉(fen)塵(chen)(chen)，它的凈化工作(zuo)上要是依(yi)靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)沉(chen)淀(dian)兩個系(xi)統來(lai)(lai)完成的，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體進人(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體受到(dao)氣(qi)(qi)(qi)(qi)(qi)流分布板以(yi)及折流板的調整后，使氣(qi)(qi)(qi)(qi)(qi)流能較(jiao)均(jun)勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷(duan)面(mian)擴大(da)的作(zuo)用(yong)下(xia)(xia)，氣(qi)(qi)(qi)(qi)(qi)流速度(du)迅(xun)速降低，其中(zhong)有些較(jiao)重的塵(chen)(chen)粒(li)便失去(qu)速度(du)而(er)沉(chen)降下(xia)(xia)來(lai)(lai)。進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體由(you)于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通人(ren)高(gao)(gao)壓直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的氣(qi)(qi)(qi)(qi)(qi)體中(zhong)存在(zai)大(da)量的電(dian)(dian)(dian)(dian)(dian)子和(he)離子，這(zhe)些電(dian)(dian)(dian)(dian)(dian)子和(he)離子與進人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的粉(fen)塵(chen)(chen)結合起來(lai)(lai)，使塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的作(zuo)用(yong)下(xia)(xia)趨(qu)向(xiang)本設(she)備陽(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)備采用(yong)負高(gao)(gao)壓制)和(he)陰(yin)(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋(shi)放(fang)出電(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積在(zai)相應(ying)的電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通過設(she)備陰(yin)(yin)陽(yang)極(ji)(ji)振打(da)系(xi)統的振打(da)，使沉(chen)積在(zai)陰(yin)(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的粉(fen)塵(chen)(chen)振落(luo)，進人(ren)集灰斗 通過排(pai)灰裝置放(fang)出，回收有物料，被)凈化的氣(qi)(qi)(qi)(qi)(qi)體排(pai)入(ru)大(da)氣(qi)(qi)(qi)(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)工作原(yuan)理是(shi)(shi)利用(yong)高壓(ya)電(dian)(dian)(dian)場(chang)使(shi)煙(yan)(yan)氣發生電(dian)(dian)(dian)離(li)，氣流(liu)中的(de)粉(fen)(fen)塵(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作用(yong)下(xia)與氣流(liu)分離(li)。負極(ji)由不同(tong)斷面(mian)形狀(zhuang)的(de)金屬導線制成(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由不同(tong)幾何形狀(zhuang)的(de)金屬板(ban)制成(cheng)，叫集(ji)(ji)塵(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)性(xing)能(neng)受粉(fen)(fen)塵(chen)性(xing)質、設備構造(zao)(zao)和(he)煙(yan)(yan)氣流(liu)速等三個(ge)因素的(de)影響。粉(fen)(fen)塵(chen)的(de)比(bi)(bi)電(dian)(dian)(dian)阻(zu)是(shi)(shi)評價導電(dian)(dian)(dian)性(xing)的(de)指標(biao)，它對(dui)除(chu)塵(chen)效率(lv)(lv)有直接的(de)影響。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)粒難以保持在集(ji)(ji)塵(chen)電(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣流(liu)。比(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)高，到達集(ji)(ji)塵(chen)電(dian)(dian)(dian)極(ji)的(de)塵(chen)粒電(dian)(dian)(dian)荷不易(yi)放(fang)出，在塵(chen)層之間形成(cheng)電(dian)(dian)(dian)壓(ya)梯度(du)會產生局部(bu)擊穿和(he)放(fang)電(dian)(dian)(dian)現象。這些情(qing)況(kuang)都會造(zao)(zao)成(cheng)除(chu)塵(chen)效率(lv)(lv)下(xia)降(jiang)。

電(dian)(dian)除塵器的(de)(de)基本原理是(shi)利用電(dian)(dian)力捕集(ji)(ji)煙氣(qi)中的(de)(de)粉(fen)塵，主要包括以(yi)下(xia)四個相(xiang)互有關的(de)(de)物理過(guo)程: (1) 氣(qi)體(ti)的(de)(de)電(dian)(dian)離(li)。(2) 粉(fen)塵的(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵向電(dian)(dian)極移(yi)動。(4) 荷電(dian)(dian)粉(fen)塵的(de)(de)捕集(ji)(ji)。
