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)(dian)(dian)(dian)除塵器是以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)(jing)化法來收捕廢氣中的(de)(de)(de)粉(fen)塵，它(ta)的(de)(de)(de)凈(jing)(jing)(jing)化工作(zuo)上要(yao)是依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極和沉淀兩個系統來完成的(de)(de)(de)，當含(han)塵氣體(ti)(ti)(ti)進(jin)人氣刺叭時，含(han)塵氣體(ti)(ti)(ti)受到氣流分布板(ban)以及(ji)折流板(ban)的(de)(de)(de)調整(zheng)后，使(shi)氣流能較(jiao)均勻地進(jin)人電(dian)(dian)(dian)(dian)(dian)場。在(zai)橫斷面擴(kuo)大的(de)(de)(de)作(zuo)用下，氣流速度(du)迅(xun)速降(jiang)(jiang)低，其中有些較(jiao)重(zhong)的(de)(de)(de)塵粒便(bian)失去速度(du)而沉降(jiang)(jiang)下來。進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含(han)塵氣體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極通(tong)(tong)人高壓(ya)直流電(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使(shi)氣體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)(de)(de)氣體(ti)(ti)(ti)中存在(zai)大量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和離子，這(zhe)些電(dian)(dian)(dian)(dian)(dian)子和離子與進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉(fen)塵結合(he)起來，使(shi)塵粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵粒在(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)用下趨(qu)向本設備陽(yang)極(正極、本設備采用負(fu)(fu)高壓(ya)制)和陰極(負(fu)(fu)極) ， 釋(shi)放出電(dian)(dian)(dian)(dian)(dian)子分別沉積(ji)在(zai)相應(ying)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極上，通(tong)(tong)過設備陰陽(yang)極振(zhen)(zhen)打系統的(de)(de)(de)振(zhen)(zhen)打，使(shi)沉積(ji)在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)極上的(de)(de)(de)粉(fen)塵振(zhen)(zhen)落，進(jin)人集(ji)灰斗 通(tong)(tong)過排灰裝置放出，回收有物料(liao)，被)凈(jing)(jing)(jing)化的(de)(de)(de)氣體(ti)(ti)(ti)排入大氣。

工作原(yuan)理

靜電(dian)(dian)除塵(chen)器的(de)(de)(de)工(gong)作原理是(shi)利用(yong)高壓(ya)電(dian)(dian)場使煙氣發生電(dian)(dian)離，氣流(liu)中的(de)(de)(de)粉塵(chen)荷電(dian)(dian)在電(dian)(dian)場作用(yong)下與氣流(liu)分離。負極(ji)由不(bu)同斷面形(xing)(xing)狀的(de)(de)(de)金屬導線制成(cheng)，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不(bu)同幾何(he)形(xing)(xing)狀的(de)(de)(de)金屬板制成(cheng)，叫(jiao)集(ji)塵(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除塵(chen)器的(de)(de)(de)性能受粉塵(chen)性質(zhi)、設備構造和煙氣流(liu)速(su)等三(san)個因素(su)的(de)(de)(de)影響。粉塵(chen)的(de)(de)(de)比電(dian)(dian)阻是(shi)評價導電(dian)(dian)性的(de)(de)(de)指標，它(ta)對除塵(chen)效(xiao)率(lv)有直接(jie)的(de)(de)(de)影響。比電(dian)(dian)阻過低，塵(chen)粒難以(yi)保持(chi)在集(ji)塵(chen)電(dian)(dian)極(ji)上，致(zhi)使其重返氣流(liu)。比電(dian)(dian)阻過高，到達集(ji)塵(chen)電(dian)(dian)極(ji)的(de)(de)(de)塵(chen)粒電(dian)(dian)荷不(bu)易放出，在塵(chen)層(ceng)之間形(xing)(xing)成(cheng)電(dian)(dian)壓(ya)梯度會產(chan)生局(ju)部擊穿和放電(dian)(dian)現象(xiang)。這些(xie)情況(kuang)都會造成(cheng)除塵(chen)效(xiao)率(lv)下降(jiang)。

電(dian)除(chu)塵(chen)(chen)器的(de)基本(ben)原理(li)是利用電(dian)力捕(bu)集煙氣(qi)中的(de)粉塵(chen)(chen)，主(zhu)要包括以下四個(ge)相(xiang)互有關的(de)物理(li)過程: (1) 氣(qi)體的(de)電(dian)離。(2) 粉塵(chen)(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉塵(chen)(chen)向電(dian)極移動。(4) 荷(he)電(dian)粉塵(chen)(chen)的(de)捕(bu)集。
