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)除塵(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)凈(jing)化法(fa)來(lai)收捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈(jing)化工作(zuo)上要是依靠電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和(he)沉(chen)淀(dian)兩個系統來(lai)完成的(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體進人(ren)(ren)氣(qi)(qi)(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)流(liu)分布(bu)板以(yi)及折(zhe)流(liu)板的(de)(de)調整(zheng)后，使(shi)(shi)氣(qi)(qi)(qi)(qi)流(liu)能較均(jun)勻地進人(ren)(ren)電(dian)(dian)(dian)場。在(zai)橫斷(duan)面(mian)擴大(da)(da)的(de)(de)作(zuo)用下，氣(qi)(qi)(qi)(qi)流(liu)速度(du)(du)迅速降低，其中(zhong)有些較重的(de)(de)塵(chen)(chen)粒便失(shi)去速度(du)(du)而(er)沉(chen)降下來(lai)。進人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體由于電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通(tong)人(ren)(ren)高(gao)壓(ya)直流(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附(fu)近(jin)產(chan)生(sheng)電(dian)(dian)(dian)暈(yun)(yun)現象，使(shi)(shi)氣(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)離(li)(li)后的(de)(de)氣(qi)(qi)(qi)(qi)體中(zhong)存(cun)在(zai)大(da)(da)量(liang)的(de)(de)電(dian)(dian)(dian)子和(he)離(li)(li)子，這些電(dian)(dian)(dian)子和(he)離(li)(li)子與(yu)進人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)結合起(qi)來(lai)，使(shi)(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)(dian)場力的(de)(de)作(zuo)用下趨向本設備(bei)(bei)陽極(ji)(ji)(正(zheng)極(ji)(ji)、本設備(bei)(bei)采用負高(gao)壓(ya)制)和(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)(chu)電(dian)(dian)(dian)子分別沉(chen)積(ji)在(zai)相應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)上，通(tong)過設備(bei)(bei)陰(yin)陽極(ji)(ji)振(zhen)打系統的(de)(de)振(zhen)打，使(shi)(shi)沉(chen)積(ji)在(zai)陰(yin)陽電(dian)(dian)(dian)極(ji)(ji)上的(de)(de)粉塵(chen)(chen)振(zhen)落(luo)，進人(ren)(ren)集灰斗 通(tong)過排灰裝置(zhi)放出(chu)(chu)，回收有物料，被)凈(jing)化的(de)(de)氣(qi)(qi)(qi)(qi)體排入(ru)大(da)(da)氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)工(gong)作(zuo)原理是(shi)利用高壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)場使煙氣發生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣流中的(de)粉塵(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場作(zuo)用下與氣流分(fen)離(li)。負極(ji)(ji)由不同(tong)斷(duan)面形(xing)狀的(de)金屬(shu)(shu)導線制成(cheng)(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同(tong)幾何形(xing)狀的(de)金屬(shu)(shu)板制成(cheng)(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)性能受粉塵(chen)(chen)(chen)(chen)(chen)性質、設備構造和煙氣流速等三個因素的(de)影響(xiang)。粉塵(chen)(chen)(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)(dian)(dian)性的(de)指(zhi)標，它對除塵(chen)(chen)(chen)(chen)(chen)效率有直接的(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)(chen)粒難(nan)以保持(chi)在(zai)集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其(qi)重返氣流。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻過高，到達(da)集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)不易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)(chen)層之間形(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)梯度會(hui)產生(sheng)局部(bu)擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)現(xian)象。這些情況都(dou)會(hui)造成(cheng)(cheng)除塵(chen)(chen)(chen)(chen)(chen)效率下降。
