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(shi)靜(jing)電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)是(shi)以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)化法(fa)來(lai)收捕廢(fei)氣(qi)中(zhong)的(de)(de)粉塵(chen)(chen)(chen)(chen)，它的(de)(de)凈(jing)化工作上(shang)要是(shi)依(yi)靠(kao)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)和沉淀兩個系統(tong)來(lai)完成的(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)(ti)進(jin)人氣(qi)刺(ci)叭(ba)時，含(han)塵(chen)(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)(ti)受到氣(qi)流分布板以及折流板的(de)(de)調整后，使(shi)氣(qi)流能較均勻地(di)進(jin)人電(dian)(dian)(dian)(dian)(dian)場。在(zai)橫斷(duan)面擴大(da)的(de)(de)作用(yong)下(xia)，氣(qi)流速(su)度(du)迅速(su)降低(di)，其中(zhong)有(you)(you)些較重的(de)(de)塵(chen)(chen)(chen)(chen)粒便失去速(su)度(du)而沉降下(xia)來(lai)。進(jin)人電(dian)(dian)(dian)(dian)(dian)場的(de)(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)通人高壓直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現象，使(shi)氣(qi)體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)(de)氣(qi)體(ti)(ti)(ti)(ti)中(zhong)存(cun)在(zai)大(da)量的(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)粉塵(chen)(chen)(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)(chen)(chen)粒帶(dai)(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作用(yong)下(xia)趨(qu)向本設備陽(yang)極(ji)(ji)(正(zheng)極(ji)(ji)、本設備采用(yong)負高壓制)和陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子分別沉積在(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設備陰(yin)陽(yang)極(ji)(ji)振(zhen)(zhen)打系統(tong)的(de)(de)振(zhen)(zhen)打，使(shi)沉積在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉塵(chen)(chen)(chen)(chen)振(zhen)(zhen)落，進(jin)人集(ji)灰斗 通過排灰裝置放出，回收有(you)(you)物料，被(bei))凈(jing)化的(de)(de)氣(qi)體(ti)(ti)(ti)(ti)排入大(da)氣(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的工作(zuo)(zuo)原理(li)是利(li)用(yong)高壓電(dian)(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)(dian)離(li)，氣流中(zhong)的粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作(zuo)(zuo)用(yong)下與氣流分離(li)。負極(ji)(ji)(ji)由不同斷面形狀的金屬(shu)導(dao)(dao)線制(zhi)成(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不同幾(ji)何形狀的金屬(shu)板制(zhi)成(cheng)，叫集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設(she)備構造和煙氣流速(su)等(deng)三個因素的影響。粉(fen)塵(chen)(chen)(chen)(chen)的比電(dian)(dian)(dian)(dian)阻是評價導(dao)(dao)電(dian)(dian)(dian)(dian)性(xing)的指(zhi)標(biao)，它對(dui)除(chu)塵(chen)(chen)(chen)(chen)效率有直接的影響。比電(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難以保持在(zai)集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上，致使其重返氣流。比電(dian)(dian)(dian)(dian)阻過高，到(dao)達集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易放出(chu)，在(zai)塵(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)壓梯(ti)度(du)會產生局部擊穿(chuan)和放電(dian)(dian)(dian)(dian)現象。這些情況都會造成(cheng)除(chu)塵(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)除(chu)塵器的(de)(de)基(ji)本原理(li)是利(li)用電(dian)(dian)力捕集(ji)煙氣(qi)中的(de)(de)粉(fen)(fen)塵，主要包括以下(xia)四(si)個相互有關的(de)(de)物理(li)過程: (1) 氣(qi)體的(de)(de)電(dian)(dian)離。(2) 粉(fen)(fen)塵的(de)(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)(fen)塵向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉(fen)(fen)塵的(de)(de)捕集(ji)。
