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(shi)靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法來(lai)收捕廢氣(qi)(qi)(qi)(qi)中(zhong)(zhong)的(de)(de)(de)粉(fen)塵，它(ta)的(de)(de)(de)凈(jing)(jing)化(hua)工作上要是(shi)依靠(kao)電(dian)(dian)(dian)(dian)(dian)暈極(ji)和沉淀兩個系(xi)統(tong)來(lai)完成的(de)(de)(de)，當含(han)塵氣(qi)(qi)(qi)(qi)體(ti)(ti)進(jin)(jin)人(ren)氣(qi)(qi)(qi)(qi)刺(ci)叭(ba)時，含(han)塵氣(qi)(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)(qi)流分布板以(yi)及折流板的(de)(de)(de)調整(zheng)后(hou)，使氣(qi)(qi)(qi)(qi)流能較均(jun)勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場。在(zai)橫(heng)斷面擴大的(de)(de)(de)作用(yong)下(xia)，氣(qi)(qi)(qi)(qi)流速度迅速降低(di)，其中(zhong)(zhong)有(you)些較重的(de)(de)(de)塵粒便失(shi)去(qu)速度而沉降下(xia)來(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)含(han)塵氣(qi)(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈極(ji)通人(ren)高壓直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)附(fu)近(jin)產生電(dian)(dian)(dian)(dian)(dian)暈現象，使氣(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)(zhong)存在(zai)大量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子和離(li)子，這些電(dian)(dian)(dian)(dian)(dian)子和離(li)子與進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉(fen)塵結合起(qi)來(lai)，使塵粒帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵粒在(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用(yong)下(xia)趨向本設(she)備(bei)陽極(ji)(正極(ji)、本設(she)備(bei)采用(yong)負高壓制)和陰極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子分別沉積在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上，通過設(she)備(bei)陰陽極(ji)振(zhen)(zhen)打系(xi)統(tong)的(de)(de)(de)振(zhen)(zhen)打，使沉積在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)粉(fen)塵振(zhen)(zhen)落，進(jin)(jin)人(ren)集灰(hui)斗 通過排灰(hui)裝置放出，回收有(you)物料，被)凈(jing)(jing)化(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)工作原(yuan)理(li)是利用高(gao)壓電(dian)(dian)(dian)(dian)場(chang)使煙氣發生電(dian)(dian)(dian)(dian)離，氣流(liu)(liu)中的(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)作用下與氣流(liu)(liu)分離。負極由不同(tong)斷面形狀的(de)金(jin)屬導(dao)線制成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由不同(tong)幾何形狀的(de)金(jin)屬板制成(cheng)，叫集塵(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(fen)塵(chen)(chen)(chen)性質、設(she)備構造和煙氣流(liu)(liu)速等三個因素的(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)比(bi)(bi)電(dian)(dian)(dian)(dian)阻(zu)是評價(jia)導(dao)電(dian)(dian)(dian)(dian)性的(de)指標，它對(dui)除(chu)塵(chen)(chen)(chen)效(xiao)率(lv)有(you)直接(jie)的(de)影響。比(bi)(bi)電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒難以(yi)保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上(shang)，致使其重返氣流(liu)(liu)。比(bi)(bi)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(ceng)之(zhi)間形成(cheng)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(xiang)。這些情況都會造成(cheng)除(chu)塵(chen)(chen)(chen)效(xiao)率(lv)下降(jiang)。

電(dian)(dian)(dian)除塵(chen)(chen)器的基本原(yuan)理是(shi)利用電(dian)(dian)(dian)力捕(bu)集煙氣中的粉(fen)(fen)塵(chen)(chen)，主要(yao)包(bao)括以(yi)下四(si)個相互有關的物理過程: (1) 氣體(ti)的電(dian)(dian)(dian)離(li)。(2) 粉(fen)(fen)塵(chen)(chen)的荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉(fen)(fen)塵(chen)(chen)向電(dian)(dian)(dian)極(ji)移(yi)動。(4) 荷(he)電(dian)(dian)(dian)粉(fen)(fen)塵(chen)(chen)的捕(bu)集。
