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)(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)法來(lai)收(shou)(shou)捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)(de)(de)(de)凈化(hua)工作(zuo)(zuo)上(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)沉淀兩個系統(tong)來(lai)完(wan)成的(de)(de)(de)(de)(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進(jin)(jin)人氣(qi)(qi)(qi)刺(ci)叭時，含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流分布板(ban)以及折流板(ban)的(de)(de)(de)(de)(de)(de)調整后(hou)，使(shi)氣(qi)(qi)(qi)流能較均勻地進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)橫斷面擴大(da)的(de)(de)(de)(de)(de)(de)作(zuo)(zuo)用(yong)(yong)下(xia)，氣(qi)(qi)(qi)流速度迅速降(jiang)低，其中有些(xie)較重的(de)(de)(de)(de)(de)(de)塵(chen)(chen)粒(li)便(bian)失去速度而沉降(jiang)下(xia)來(lai)。進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人高(gao)壓直流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近(jin)產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中存在(zai)大(da)量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)離子(zi)(zi)與進(jin)(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)(de)(de)(de)作(zuo)(zuo)用(yong)(yong)下(xia)趨向本設(she)備(bei)陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設(she)備(bei)采用(yong)(yong)負高(gao)壓制(zhi))和(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分別沉積在(zai)相應的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通過(guo)設(she)備(bei)陰陽極(ji)(ji)(ji)振打(da)系統(tong)的(de)(de)(de)(de)(de)(de)振打(da)，使(shi)沉積在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)振落，進(jin)(jin)人集灰(hui)斗(dou) 通過(guo)排灰(hui)裝置(zhi)放出，回收(shou)(shou)有物(wu)料，被(bei))凈化(hua)的(de)(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排入大(da)氣(qi)(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)除塵(chen)器的(de)工作(zuo)原(yuan)理是(shi)利用(yong)高壓電(dian)(dian)場(chang)使煙氣發生電(dian)(dian)離，氣流中的(de)粉塵(chen)荷(he)電(dian)(dian)在電(dian)(dian)場(chang)作(zuo)用(yong)下與氣流分離。負(fu)極(ji)由不(bu)(bu)同斷面形狀的(de)金屬導線制成(cheng)(cheng)，叫(jiao)(jiao)放電(dian)(dian)電(dian)(dian)極(ji)。正(zheng)極(ji)由不(bu)(bu)同幾何形狀的(de)金屬板制成(cheng)(cheng)，叫(jiao)(jiao)集塵(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除塵(chen)器的(de)性(xing)能受粉塵(chen)性(xing)質、設備構造和煙氣流速等三個因素(su)的(de)影響。粉塵(chen)的(de)比電(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)性(xing)的(de)指標，它對(dui)除塵(chen)效率有直接的(de)影響。比電(dian)(dian)阻(zu)過低，塵(chen)粒(li)難以保(bao)持在集塵(chen)電(dian)(dian)極(ji)上，致使其重返氣流。比電(dian)(dian)阻(zu)過高，到達集塵(chen)電(dian)(dian)極(ji)的(de)塵(chen)粒(li)電(dian)(dian)荷(he)不(bu)(bu)易放出，在塵(chen)層之間形成(cheng)(cheng)電(dian)(dian)壓梯度(du)會產生局部擊穿和放電(dian)(dian)現(xian)象。這些情(qing)況都(dou)會造成(cheng)(cheng)除塵(chen)效率下降。

電除(chu)塵器的(de)基本(ben)原理是利用電力捕集(ji)煙氣(qi)中的(de)粉(fen)(fen)塵，主(zhu)要包(bao)括以(yi)下四個相互有(you)關的(de)物理過程: (1) 氣(qi)體(ti)的(de)電離。(2) 粉(fen)(fen)塵的(de)荷(he)電。(3) 荷(he)電粉(fen)(fen)塵向電極移動。(4) 荷(he)電粉(fen)(fen)塵的(de)捕集(ji)。
