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)(dian)除塵(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化法來(lai)收捕廢氣(qi)中(zhong)的(de)(de)(de)(de)粉塵(chen)(chen)，它(ta)的(de)(de)(de)(de)凈化工作上要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和沉(chen)淀兩(liang)個(ge)系(xi)統來(lai)完(wan)成的(de)(de)(de)(de)，當含塵(chen)(chen)氣(qi)體進(jin)(jin)人氣(qi)刺叭時，含塵(chen)(chen)氣(qi)體受(shou)到氣(qi)流(liu)分布板以及折流(liu)板的(de)(de)(de)(de)調整后，使氣(qi)流(liu)能較均(jun)勻地進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場。在橫(heng)斷面(mian)擴大(da)的(de)(de)(de)(de)作用下，氣(qi)流(liu)速(su)(su)度(du)迅速(su)(su)降低，其(qi)中(zhong)有(you)些(xie)(xie)較重的(de)(de)(de)(de)塵(chen)(chen)粒便失去速(su)(su)度(du)而沉(chen)降下來(lai)。進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含塵(chen)(chen)氣(qi)體由于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)人高(gao)壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象(xiang)，使氣(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)體中(zhong)存在大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這些(xie)(xie)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)與進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉塵(chen)(chen)結合(he)起來(lai)，使塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作用下趨向本設備陽極(ji)(ji)(正極(ji)(ji)、本設備采用負高(gao)壓制)和陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋(shi)放(fang)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積(ji)在相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通(tong)過(guo)(guo)設備陰(yin)陽極(ji)(ji)振(zhen)打系(xi)統的(de)(de)(de)(de)振(zhen)打，使沉(chen)積(ji)在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)粉塵(chen)(chen)振(zhen)落，進(jin)(jin)人集灰斗 通(tong)過(guo)(guo)排灰裝置放(fang)出(chu)，回收有(you)物料，被)凈化的(de)(de)(de)(de)氣(qi)體排入大(da)氣(qi)。

工(gong)作(zuo)原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)工作原理是利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣發生電(dian)(dian)(dian)(dian)(dian)離，氣流(liu)(liu)中的(de)(de)粉塵(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作用下與氣流(liu)(liu)分離。負極(ji)(ji)由不(bu)同(tong)(tong)斷面形(xing)(xing)狀(zhuang)的(de)(de)金(jin)屬導線(xian)制成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由不(bu)同(tong)(tong)幾何(he)形(xing)(xing)狀(zhuang)的(de)(de)金(jin)屬板制成(cheng)，叫集(ji)(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)性(xing)能(neng)受粉塵(chen)性(xing)質(zhi)、設備(bei)構造(zao)和煙(yan)氣流(liu)(liu)速等三(san)個因素的(de)(de)影(ying)響(xiang)(xiang)。粉塵(chen)的(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對(dui)除(chu)塵(chen)效(xiao)率有(you)直接的(de)(de)影(ying)響(xiang)(xiang)。比電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)粒難以保(bao)持(chi)在(zai)集(ji)(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致(zhi)使其重返氣流(liu)(liu)。比電(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到達集(ji)(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不(bu)易放(fang)出，在(zai)塵(chen)層之(zhi)間形(xing)(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產(chan)生局部(bu)擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造(zao)成(cheng)除(chu)塵(chen)效(xiao)率下降(jiang)。
