XWD型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)除塵(chen)(chen)器是(shi)以靜電(dian)(dian)凈(jing)化法來收(shou)(shou)捕廢(fei)氣(qi)(qi)(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化工作(zuo)上(shang)要是(shi)依靠電(dian)(dian)暈極(ji)和(he)沉淀兩個系統來完成(cheng)的(de)(de)(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)(qi)體進(jin)人氣(qi)(qi)(qi)(qi)(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)(qi)體受到氣(qi)(qi)(qi)(qi)(qi)(qi)流(liu)分布(bu)板以及折流(liu)板的(de)(de)(de)(de)調整(zheng)后，使氣(qi)(qi)(qi)(qi)(qi)(qi)流(liu)能較(jiao)均勻地進(jin)人電(dian)(dian)場。在(zai)橫斷面擴大的(de)(de)(de)(de)作(zuo)用(yong)(yong)下，氣(qi)(qi)(qi)(qi)(qi)(qi)流(liu)速(su)度(du)迅速(su)降(jiang)低(di)，其中有(you)些較(jiao)重的(de)(de)(de)(de)塵(chen)(chen)粒便失去速(su)度(du)而(er)沉降(jiang)下來。進(jin)人電(dian)(dian)場的(de)(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)(qi)體由于(yu)電(dian)(dian)暈極(ji)通(tong)人高壓(ya)直流(liu)電(dian)(dian)，則在(zai)電(dian)(dian)暈極(ji)附(fu)近(jin)產生(sheng)電(dian)(dian)暈現象，使氣(qi)(qi)(qi)(qi)(qi)(qi)體電(dian)(dian)離(li)，電(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體中存在(zai)大量的(de)(de)(de)(de)電(dian)(dian)子和(he)離(li)子，這些電(dian)(dian)子和(he)離(li)子與(yu)進(jin)人電(dian)(dian)場的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)結(jie)合起來，使塵(chen)(chen)粒帶(dai)電(dian)(dian)，帶(dai)電(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)場力的(de)(de)(de)(de)作(zuo)用(yong)(yong)下趨向(xiang)本設(she)備(bei)陽極(ji)(正(zheng)極(ji)、本設(she)備(bei)采用(yong)(yong)負高壓(ya)制)和(he)陰極(ji)(負極(ji)) ， 釋(shi)放出電(dian)(dian)子分別沉積在(zai)相(xiang)應的(de)(de)(de)(de)電(dian)(dian)極(ji)上(shang)，通(tong)過設(she)備(bei)陰陽極(ji)振打系統的(de)(de)(de)(de)振打，使沉積在(zai)陰陽電(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)粉(fen)(fen)塵(chen)(chen)振落，進(jin)人集灰斗(dou) 通(tong)過排(pai)灰裝置放出，回收(shou)(shou)有(you)物料，被(bei))凈(jing)化的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)(qi)體排(pai)入大氣(qi)(qi)(qi)(qi)(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)工作(zuo)原理是利(li)用(yong)高(gao)壓電(dian)(dian)(dian)(dian)場(chang)使(shi)煙氣發(fa)生電(dian)(dian)(dian)(dian)離(li)，氣流中的(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)作(zuo)用(yong)下(xia)與氣流分離(li)。負極由(you)不同斷面形狀的(de)金(jin)屬導(dao)線制成，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由(you)不同幾何形狀的(de)金(jin)屬板制成，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)性能受粉塵(chen)(chen)(chen)性質、設備構造和煙氣流速等(deng)三個因素的(de)影(ying)響(xiang)。粉塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)阻(zu)是評價導(dao)電(dian)(dian)(dian)(dian)性的(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)效(xiao)(xiao)率有直接(jie)的(de)影(ying)響(xiang)。比電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒難(nan)以(yi)保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上，致使(shi)其重返氣流。比電(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到達(da)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)(chen)層之間(jian)形成電(dian)(dian)(dian)(dian)壓梯(ti)度會產生局部擊穿和放(fang)電(dian)(dian)(dian)(dian)現象。這些情(qing)況(kuang)都(dou)會造成除(chu)塵(chen)(chen)(chen)效(xiao)(xiao)率下(xia)降。

電除(chu)塵(chen)(chen)器(qi)的(de)基(ji)本(ben)原理(li)是利用電力捕(bu)集(ji)(ji)煙氣(qi)中的(de)粉(fen)塵(chen)(chen)，主要包括以下四個相互(hu)有(you)關的(de)物理(li)過程: (1) 氣(qi)體(ti)的(de)電離。(2) 粉(fen)塵(chen)(chen)的(de)荷電。(3) 荷電粉(fen)塵(chen)(chen)向電極移(yi)動。(4) 荷電粉(fen)塵(chen)(chen)的(de)捕(bu)集(ji)(ji)。
