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)(dian)除塵(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈化法來收捕廢氣(qi)中(zhong)(zhong)的(de)粉塵(chen)，它的(de)凈化工(gong)作(zuo)上(shang)要是依(yi)靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)(he)沉淀兩(liang)個(ge)系統來完成的(de)，當含(han)塵(chen)氣(qi)體(ti)進(jin)人(ren)氣(qi)刺叭時，含(han)塵(chen)氣(qi)體(ti)受(shou)到氣(qi)流(liu)分布板以(yi)及折流(liu)板的(de)調(diao)整(zheng)后(hou)，使氣(qi)流(liu)能較均勻(yun)地(di)進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場。在(zai)橫斷面擴(kuo)大(da)的(de)作(zuo)用下，氣(qi)流(liu)速度(du)(du)迅速降(jiang)低，其中(zhong)(zhong)有些較重的(de)塵(chen)粒便失去速度(du)(du)而沉降(jiang)下來。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)含(han)塵(chen)氣(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通人(ren)高壓(ya)(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)氣(qi)體(ti)中(zhong)(zhong)存在(zai)大(da)量的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和(he)(he)離子(zi)(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和(he)(he)離子(zi)(zi)(zi)與(yu)進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場的(de)粉塵(chen)結(jie)合起來，使塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)作(zuo)用下趨向本(ben)設備陽極(ji)(ji)(正極(ji)(ji)、本(ben)設備采用負高壓(ya)(ya)制)和(he)(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)分別沉積(ji)在(zai)相(xiang)應的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設備陰(yin)陽極(ji)(ji)振打系統的(de)振打，使沉積(ji)在(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)粉塵(chen)振落(luo)，進(jin)人(ren)集灰(hui)斗 通過排灰(hui)裝置放出，回(hui)收有物料，被)凈化的(de)氣(qi)體(ti)排入大(da)氣(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)(de)工(gong)作原理是(shi)利用高壓電(dian)(dian)(dian)場(chang)使(shi)煙(yan)氣(qi)(qi)(qi)發生電(dian)(dian)(dian)離，氣(qi)(qi)(qi)流(liu)中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場(chang)作用下(xia)與氣(qi)(qi)(qi)流(liu)分(fen)離。負(fu)極(ji)由(you)不(bu)同(tong)斷(duan)面(mian)形狀(zhuang)的(de)(de)(de)金屬導線制(zhi)成(cheng)，叫放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由(you)不(bu)同(tong)幾何形狀(zhuang)的(de)(de)(de)金屬板制(zhi)成(cheng)，叫集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)(de)性能(neng)受粉(fen)(fen)塵(chen)(chen)(chen)性質、設備構造和煙(yan)氣(qi)(qi)(qi)流(liu)速等三個因素的(de)(de)(de)影(ying)響。粉(fen)(fen)塵(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)阻是(shi)評價(jia)導電(dian)(dian)(dian)性的(de)(de)(de)指標(biao)，它對除(chu)塵(chen)(chen)(chen)效率有直接的(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以(yi)保(bao)持(chi)在(zai)集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致(zhi)使(shi)其重返氣(qi)(qi)(qi)流(liu)。比電(dian)(dian)(dian)阻過高，到達集(ji)(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易放(fang)(fang)出，在(zai)塵(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)壓梯度會(hui)產生局部(bu)擊穿和放(fang)(fang)電(dian)(dian)(dian)現象。這些情況(kuang)都會(hui)造成(cheng)除(chu)塵(chen)(chen)(chen)效率下(xia)降。

電除(chu)塵(chen)器的(de)(de)基本原理(li)(li)是(shi)利用電力捕集(ji)煙氣中的(de)(de)粉塵(chen)，主要包(bao)括以下四個相(xiang)互(hu)有(you)關的(de)(de)物理(li)(li)過程: (1) 氣體的(de)(de)電離。(2) 粉塵(chen)的(de)(de)荷電。(3) 荷電粉塵(chen)向電極移動。(4) 荷電粉塵(chen)的(de)(de)捕集(ji)。
