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(wo)式靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)是以靜(jing)電(dian)(dian)(dian)凈(jing)化(hua)(hua)法來收捕(bu)廢氣(qi)(qi)中(zhong)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化(hua)(hua)工作(zuo)上(shang)要(yao)是依靠電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)和(he)沉(chen)(chen)淀兩個(ge)系統來完成的(de)(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)進(jin)人(ren)(ren)(ren)(ren)(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)受(shou)到氣(qi)(qi)流(liu)分布板(ban)以及(ji)折流(liu)板(ban)的(de)(de)(de)(de)調整后(hou)，使(shi)氣(qi)(qi)流(liu)能較均勻地進(jin)人(ren)(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)。在橫斷面擴大的(de)(de)(de)(de)作(zuo)用(yong)下(xia)，氣(qi)(qi)流(liu)速(su)度(du)(du)迅速(su)降(jiang)(jiang)低，其中(zhong)有些較重(zhong)的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)(chen)粒便(bian)失去速(su)度(du)(du)而(er)沉(chen)(chen)降(jiang)(jiang)下(xia)來。進(jin)人(ren)(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含塵(chen)(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)通(tong)人(ren)(ren)(ren)(ren)(ren)高壓直流(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)氣(qi)(qi)體(ti)中(zhong)存在大量的(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這(zhe)些電(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與(yu)進(jin)人(ren)(ren)(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)結合起來，使(shi)塵(chen)(chen)(chen)(chen)(chen)(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)(chen)(chen)粒在電(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作(zuo)用(yong)下(xia)趨向本設(she)備陽極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設(she)備采用(yong)負(fu)高壓制)和(he)陰(yin)極(ji)(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子(zi)分別(bie)沉(chen)(chen)積(ji)在相(xiang)應的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)，通(tong)過設(she)備陰(yin)陽極(ji)(ji)(ji)(ji)振(zhen)(zhen)打系統的(de)(de)(de)(de)振(zhen)(zhen)打，使(shi)沉(chen)(chen)積(ji)在陰(yin)陽電(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)振(zhen)(zhen)落，進(jin)人(ren)(ren)(ren)(ren)(ren)集灰(hui)(hui)斗 通(tong)過排灰(hui)(hui)裝(zhuang)置放出，回(hui)收有物料，被)凈(jing)化(hua)(hua)的(de)(de)(de)(de)氣(qi)(qi)體(ti)排入大氣(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)(de)(de)(de)工作(zuo)原理是利用高壓(ya)電(dian)(dian)(dian)場使煙(yan)氣(qi)發(fa)生(sheng)電(dian)(dian)(dian)離，氣(qi)流中的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作(zuo)用下與氣(qi)流分離。負極由不(bu)(bu)同斷面形(xing)狀的(de)(de)(de)(de)(de)金(jin)屬導線制成(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由不(bu)(bu)同幾何形(xing)狀的(de)(de)(de)(de)(de)金(jin)屬板制成(cheng)，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)(de)(de)(de)性(xing)能受(shou)粉(fen)塵(chen)(chen)性(xing)質、設(she)備(bei)構造和煙(yan)氣(qi)流速等(deng)三(san)個(ge)因素的(de)(de)(de)(de)(de)影(ying)響。粉(fen)塵(chen)(chen)的(de)(de)(de)(de)(de)比(bi)(bi)(bi)電(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)(de)指標，它對除(chu)塵(chen)(chen)效率(lv)(lv)有(you)直接的(de)(de)(de)(de)(de)影(ying)響。比(bi)(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)(guo)低，塵(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)極上，致使其重(zhong)返氣(qi)流。比(bi)(bi)(bi)電(dian)(dian)(dian)阻(zu)過(guo)(guo)高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)極的(de)(de)(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)(bu)易放(fang)出，在塵(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)壓(ya)梯(ti)度會產生(sheng)局部擊穿和放(fang)電(dian)(dian)(dian)現象。這些情(qing)況都會造成(cheng)除(chu)塵(chen)(chen)效率(lv)(lv)下降(jiang)。

電(dian)(dian)除(chu)塵器的(de)基本原理是利(li)用電(dian)(dian)力捕集煙(yan)氣中的(de)粉(fen)塵，主要包括(kuo)以下(xia)四個(ge)相(xiang)互有關的(de)物理過程: (1) 氣體的(de)電(dian)(dian)離(li)。(2) 粉(fen)塵的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)塵向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉(fen)塵的(de)捕集。
