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)(dian)(dian)除塵(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)凈化(hua)法來收(shou)捕廢氣(qi)(qi)(qi)中的(de)(de)(de)(de)(de)粉塵(chen)，它的(de)(de)(de)(de)(de)凈化(hua)工作(zuo)上要是(shi)依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)沉淀兩個系統來完成的(de)(de)(de)(de)(de)，當含(han)(han)塵(chen)氣(qi)(qi)(qi)體(ti)(ti)進(jin)(jin)人(ren)(ren)氣(qi)(qi)(qi)刺(ci)叭時(shi)，含(han)(han)塵(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流分(fen)布板以(yi)及折流板的(de)(de)(de)(de)(de)調整后，使(shi)(shi)(shi)氣(qi)(qi)(qi)流能較(jiao)均(jun)勻地(di)進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴大(da)的(de)(de)(de)(de)(de)作(zuo)用下，氣(qi)(qi)(qi)流速(su)度迅速(su)降低，其(qi)中有些較(jiao)重(zhong)的(de)(de)(de)(de)(de)塵(chen)粒便失去速(su)度而(er)沉降下來。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)含(han)(han)塵(chen)氣(qi)(qi)(qi)體(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)人(ren)(ren)高壓(ya)(ya)直流電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近(jin)產生(sheng)電(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)(shi)(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離(li)(li)(li)，電(dian)(dian)(dian)(dian)離(li)(li)(li)后的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中存在(zai)大(da)量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子和(he)離(li)(li)(li)子，這些電(dian)(dian)(dian)(dian)子和(he)離(li)(li)(li)子與(yu)進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)粉塵(chen)結合起來，使(shi)(shi)(shi)塵(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒在(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)作(zuo)用下趨(qu)向本設備陽(yang)極(ji)(ji)(正極(ji)(ji)、本設備采用負(fu)(fu)高壓(ya)(ya)制)和(he)陰極(ji)(ji)(負(fu)(fu)極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子分(fen)別沉積在(zai)相(xiang)應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上，通(tong)過(guo)(guo)設備陰陽(yang)極(ji)(ji)振(zhen)打系統的(de)(de)(de)(de)(de)振(zhen)打，使(shi)(shi)(shi)沉積在(zai)陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)(de)粉塵(chen)振(zhen)落(luo)，進(jin)(jin)人(ren)(ren)集(ji)灰斗 通(tong)過(guo)(guo)排灰裝(zhuang)置(zhi)放出，回收(shou)有物料，被)凈化(hua)的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排入大(da)氣(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)工作(zuo)原理是(shi)利用高壓電(dian)(dian)(dian)場(chang)使煙氣發生(sheng)電(dian)(dian)(dian)離，氣流(liu)中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作(zuo)用下與氣流(liu)分離。負極(ji)由不同(tong)斷面形(xing)狀的(de)(de)(de)金屬導(dao)線制成(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不同(tong)幾何(he)形(xing)狀的(de)(de)(de)金屬板制成(cheng)，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)性能受粉(fen)塵(chen)(chen)(chen)(chen)性質、設備構造和煙氣流(liu)速等(deng)三個因素的(de)(de)(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)阻是(shi)評(ping)價導(dao)電(dian)(dian)(dian)性的(de)(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)(chen)效(xiao)率有(you)直接的(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其重返(fan)氣流(liu)。比電(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)(chen)層(ceng)之(zhi)間形(xing)成(cheng)電(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿和放(fang)電(dian)(dian)(dian)現象。這些情況(kuang)都(dou)會造成(cheng)除(chu)塵(chen)(chen)(chen)(chen)效(xiao)率下降。

電(dian)(dian)除塵(chen)器的(de)(de)(de)基本原理(li)(li)是利用電(dian)(dian)力捕集煙氣中的(de)(de)(de)粉塵(chen)，主要包(bao)括以下四個相互有關(guan)的(de)(de)(de)物理(li)(li)過程: (1) 氣體的(de)(de)(de)電(dian)(dian)離。(2) 粉塵(chen)的(de)(de)(de)荷(he)(he)電(dian)(dian)。(3) 荷(he)(he)電(dian)(dian)粉塵(chen)向電(dian)(dian)極移動。(4) 荷(he)(he)電(dian)(dian)粉塵(chen)的(de)(de)(de)捕集。
