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)除塵(chen)器是以靜電(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)(lai)收(shou)捕廢氣中(zhong)的粉(fen)塵(chen)，它(ta)的凈(jing)化(hua)工作(zuo)(zuo)上要是依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)沉(chen)淀兩個系(xi)統(tong)來(lai)(lai)完成的，當含(han)塵(chen)氣體(ti)進(jin)人(ren)(ren)氣刺叭時，含(han)塵(chen)氣體(ti)受到氣流分(fen)布板以及折流板的調(diao)整后，使(shi)(shi)(shi)(shi)氣流能較(jiao)(jiao)均(jun)勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場。在(zai)(zai)(zai)橫斷(duan)面擴大的作(zuo)(zuo)用下(xia)，氣流速度迅速降低，其中(zhong)有(you)些較(jiao)(jiao)重(zhong)的塵(chen)粒便(bian)失去速度而沉(chen)降下(xia)來(lai)(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場的含(han)塵(chen)氣體(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通(tong)人(ren)(ren)高壓(ya)直(zhi)流電(dian)(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)現(xian)象(xiang)，使(shi)(shi)(shi)(shi)氣體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的氣體(ti)中(zhong)存在(zai)(zai)(zai)大量的電(dian)(dian)(dian)(dian)子和(he)離(li)子，這些電(dian)(dian)(dian)(dian)子和(he)離(li)子與(yu)進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場的粉(fen)塵(chen)結(jie)合起來(lai)(lai)，使(shi)(shi)(shi)(shi)塵(chen)粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)粒在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)場力的作(zuo)(zuo)用下(xia)趨向本設(she)(she)備陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設(she)(she)備采用負(fu)(fu)高壓(ya)制(zhi))和(he)陰極(ji)(ji)(ji)(負(fu)(fu)極(ji)(ji)(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)子分(fen)別沉(chen)積在(zai)(zai)(zai)相應的電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，通(tong)過設(she)(she)備陰陽(yang)極(ji)(ji)(ji)振(zhen)打(da)(da)系(xi)統(tong)的振(zhen)打(da)(da)，使(shi)(shi)(shi)(shi)沉(chen)積在(zai)(zai)(zai)陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上的粉(fen)塵(chen)振(zhen)落，進(jin)人(ren)(ren)集(ji)灰斗 通(tong)過排灰裝置放(fang)出，回收(shou)有(you)物料，被)凈(jing)化(hua)的氣體(ti)排入大氣。

工作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)工作原理是利用(yong)(yong)高壓(ya)電(dian)(dian)(dian)場使煙氣(qi)(qi)發生電(dian)(dian)(dian)離，氣(qi)(qi)流中的(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作用(yong)(yong)下(xia)與氣(qi)(qi)流分離。負極(ji)(ji)由不(bu)(bu)同斷面形(xing)狀的(de)(de)金屬(shu)導線制成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)(bu)同幾(ji)何形(xing)狀的(de)(de)金屬(shu)板(ban)制成(cheng)，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)性(xing)能受粉塵(chen)(chen)性(xing)質(zhi)、設備(bei)構造(zao)和煙氣(qi)(qi)流速等三個(ge)因素的(de)(de)影響。粉塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除塵(chen)(chen)效(xiao)率有直(zhi)接的(de)(de)影響。比(bi)電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)粒(li)難以保持(chi)在(zai)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使其(qi)重返氣(qi)(qi)流。比(bi)電(dian)(dian)(dian)阻(zu)過高，到達(da)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)荷不(bu)(bu)易放(fang)出，在(zai)塵(chen)(chen)層之(zhi)間(jian)形(xing)成(cheng)電(dian)(dian)(dian)壓(ya)梯度(du)會(hui)產生局部擊穿和放(fang)電(dian)(dian)(dian)現象。這些情況(kuang)都會(hui)造(zao)成(cheng)除塵(chen)(chen)效(xiao)率下(xia)降。

電(dian)除(chu)塵(chen)器(qi)的基(ji)本(ben)原(yuan)理是利用電(dian)力捕集(ji)煙氣(qi)(qi)中的粉(fen)塵(chen)，主要包(bao)括以下四個相(xiang)互有關的物理過程: (1) 氣(qi)(qi)體(ti)的電(dian)離。(2) 粉(fen)塵(chen)的荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)向電(dian)極移動。(4) 荷電(dian)粉(fen)塵(chen)的捕集(ji)。
