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)除塵(chen)(chen)(chen)器是以(yi)(yi)靜(jing)電(dian)(dian)凈(jing)化(hua)法來收捕廢氣(qi)(qi)中(zhong)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化(hua)工(gong)作(zuo)上要是依(yi)靠電(dian)(dian)暈(yun)極(ji)(ji)和(he)沉淀兩(liang)個系(xi)統來完(wan)成的(de)(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進人(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受到(dao)氣(qi)(qi)流(liu)分布板以(yi)(yi)及折(zhe)流(liu)板的(de)(de)(de)(de)調(diao)整后(hou)，使(shi)氣(qi)(qi)流(liu)能較均勻地進人(ren)電(dian)(dian)場。在(zai)橫斷(duan)面擴(kuo)大的(de)(de)(de)(de)作(zuo)用(yong)(yong)下，氣(qi)(qi)流(liu)速(su)度(du)迅速(su)降低，其(qi)中(zhong)有些(xie)較重的(de)(de)(de)(de)塵(chen)(chen)(chen)粒便失去速(su)度(du)而(er)沉降下來。進人(ren)電(dian)(dian)場的(de)(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)暈(yun)極(ji)(ji)通人(ren)高(gao)壓(ya)直流(liu)電(dian)(dian)，則在(zai)電(dian)(dian)暈(yun)極(ji)(ji)附(fu)近產生電(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)離，電(dian)(dian)離后(hou)的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)中(zhong)存在(zai)大量的(de)(de)(de)(de)電(dian)(dian)子(zi)和(he)離子(zi)，這些(xie)電(dian)(dian)子(zi)和(he)離子(zi)與進人(ren)電(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結合(he)起來，使(shi)塵(chen)(chen)(chen)粒帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵(chen)(chen)(chen)粒在(zai)電(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用(yong)(yong)下趨向本(ben)設(she)備陽(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設(she)備采(cai)用(yong)(yong)負高(gao)壓(ya)制)和(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)子(zi)分別沉積(ji)(ji)在(zai)相(xiang)應的(de)(de)(de)(de)電(dian)(dian)極(ji)(ji)上，通過設(she)備陰陽(yang)極(ji)(ji)振(zhen)打系(xi)統的(de)(de)(de)(de)振(zhen)打，使(shi)沉積(ji)(ji)在(zai)陰陽(yang)電(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振(zhen)落(luo)，進人(ren)集灰斗 通過排灰裝(zhuang)置(zhi)放出，回收有物(wu)料，被(bei))凈(jing)化(hua)的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)。

工作原理(li)

靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵器的(de)(de)(de)工作(zuo)原(yuan)理是利用高壓電(dian)(dian)(dian)(dian)場使煙(yan)氣發(fa)生電(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)(de)(de)粉塵荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作(zuo)用下(xia)與氣流(liu)分離。負極(ji)(ji)(ji)(ji)由不(bu)同(tong)斷面形(xing)(xing)狀的(de)(de)(de)金(jin)(jin)屬導線制成(cheng)(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)。正極(ji)(ji)(ji)(ji)由不(bu)同(tong)幾何形(xing)(xing)狀的(de)(de)(de)金(jin)(jin)屬板制成(cheng)(cheng)，叫集(ji)塵電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)。靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵器的(de)(de)(de)性能受粉塵性質、設備構造和煙(yan)氣流(liu)速(su)等三個因素的(de)(de)(de)影(ying)響(xiang)。粉塵的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)(dian)性的(de)(de)(de)指標，它對除(chu)塵效率(lv)有直接的(de)(de)(de)影(ying)響(xiang)。比(bi)電(dian)(dian)(dian)(dian)阻過低，塵粒難以保持在集(ji)塵電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上，致(zhi)使其重(zhong)返氣流(liu)。比(bi)電(dian)(dian)(dian)(dian)阻過高，到達集(ji)塵電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)的(de)(de)(de)塵粒電(dian)(dian)(dian)(dian)荷不(bu)易放(fang)出，在塵層之間形(xing)(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)壓梯(ti)度會產(chan)生局部擊(ji)穿和放(fang)電(dian)(dian)(dian)(dian)現象(xiang)。這(zhe)些情況都會造成(cheng)(cheng)除(chu)塵效率(lv)下(xia)降。

電(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)基本(ben)原理是利(li)用(yong)電(dian)(dian)(dian)力(li)捕(bu)集(ji)(ji)煙(yan)氣中的(de)(de)粉(fen)塵(chen)(chen)，主(zhu)要(yao)包括(kuo)以下四個相(xiang)互有關的(de)(de)物理過程: (1) 氣體的(de)(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)(chen)的(de)(de)荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)(dian)極(ji)移(yi)動。(4) 荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)(chen)的(de)(de)捕(bu)集(ji)(ji)。
