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)除塵(chen)(chen)(chen)(chen)器(qi)是(shi)以(yi)靜電(dian)(dian)(dian)凈(jing)化法來(lai)收捕廢氣(qi)中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，它的(de)(de)凈(jing)化工作上要是(shi)依靠電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和沉淀兩個系(xi)統來(lai)完(wan)成的(de)(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)體(ti)進(jin)(jin)人(ren)(ren)(ren)氣(qi)刺(ci)叭時，含塵(chen)(chen)(chen)(chen)氣(qi)體(ti)受到氣(qi)流(liu)(liu)分(fen)布板以(yi)及折流(liu)(liu)板的(de)(de)調整(zheng)后，使氣(qi)流(liu)(liu)能較(jiao)均勻地進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)。在(zai)橫斷面(mian)擴(kuo)大的(de)(de)作用(yong)下，氣(qi)流(liu)(liu)速(su)度(du)迅速(su)降低，其中有些較(jiao)重(zhong)的(de)(de)塵(chen)(chen)(chen)(chen)粒便失去速(su)度(du)而沉降下來(lai)。進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)體(ti)由(you)于電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通(tong)人(ren)(ren)(ren)高壓(ya)直流(liu)(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)暈(yun)現象，使氣(qi)體(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)體(ti)中存在(zai)大量的(de)(de)電(dian)(dian)(dian)子和離(li)子，這些電(dian)(dian)(dian)子和離(li)子與進(jin)(jin)人(ren)(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)結合起來(lai)，使塵(chen)(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)作用(yong)下趨向本(ben)設(she)備(bei)陽(yang)極(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)、本(ben)設(she)備(bei)采(cai)用(yong)負(fu)高壓(ya)制)和陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)子分(fen)別沉積(ji)(ji)在(zai)相應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)上，通(tong)過設(she)備(bei)陰(yin)陽(yang)極(ji)(ji)(ji)振打系(xi)統的(de)(de)振打，使沉積(ji)(ji)在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)振落(luo)，進(jin)(jin)人(ren)(ren)(ren)集灰斗(dou) 通(tong)過排(pai)灰裝(zhuang)置放(fang)出(chu)，回收有物料，被)凈(jing)化的(de)(de)氣(qi)體(ti)排(pai)入大氣(qi)。

工(gong)作原理

靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)工作原理是利用高壓電(dian)(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，氣流中的(de)(de)(de)粉塵(chen)(chen)荷(he)(he)電(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)場作用下與(yu)氣流分離(li)。負極(ji)由(you)不(bu)同斷面形(xing)狀的(de)(de)(de)金屬導線制成(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。正(zheng)極(ji)由(you)不(bu)同幾何形(xing)狀的(de)(de)(de)金屬板制成(cheng)，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)性能受(shou)粉塵(chen)(chen)性質、設備(bei)構造和(he)煙氣流速等三個因素(su)的(de)(de)(de)影(ying)響。粉塵(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)是評價導電(dian)(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)指(zhi)標，它對除塵(chen)(chen)效(xiao)率(lv)有直接的(de)(de)(de)影(ying)響。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)粒難以保(bao)持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，致(zhi)使(shi)其重返氣流。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)荷(he)(he)不(bu)易放出，在塵(chen)(chen)層(ceng)之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部擊(ji)穿和(he)放電(dian)(dian)(dian)(dian)(dian)(dian)現(xian)象。這些情(qing)況都會造成(cheng)除塵(chen)(chen)效(xiao)率(lv)下降。

電(dian)(dian)除塵器(qi)的(de)(de)(de)基本原理(li)是利(li)用電(dian)(dian)力捕(bu)集煙氣中的(de)(de)(de)粉塵，主要(yao)包括以下(xia)四個(ge)相(xiang)互有關的(de)(de)(de)物(wu)理(li)過程(cheng): (1) 氣體(ti)的(de)(de)(de)電(dian)(dian)離。(2) 粉塵的(de)(de)(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉塵向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉塵的(de)(de)(de)捕(bu)集。
