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(wo)式靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法(fa)來收(shou)捕廢氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)粉塵(chen)，它的(de)(de)(de)凈(jing)(jing)化(hua)工作上(shang)(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)暈極(ji)(ji)和沉(chen)淀(dian)兩個系統來完成的(de)(de)(de)，當含塵(chen)氣(qi)(qi)(qi)(qi)體(ti)進人(ren)氣(qi)(qi)(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)流分布板(ban)(ban)以(yi)及(ji)折流板(ban)(ban)的(de)(de)(de)調(diao)整(zheng)后(hou)，使(shi)(shi)氣(qi)(qi)(qi)(qi)流能(neng)較均勻地進人(ren)電(dian)(dian)(dian)(dian)場。在橫(heng)斷面擴(kuo)大(da)的(de)(de)(de)作用下，氣(qi)(qi)(qi)(qi)流速度迅(xun)速降(jiang)低，其中(zhong)有些較重的(de)(de)(de)塵(chen)粒便失去速度而沉(chen)降(jiang)下來。進人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)(ji)通人(ren)高壓直流電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)氣(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)中(zhong)存在大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與進人(ren)電(dian)(dian)(dian)(dian)場的(de)(de)(de)粉塵(chen)結(jie)合起(qi)來，使(shi)(shi)塵(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)粒在電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用下趨向本(ben)設備陽極(ji)(ji)(正極(ji)(ji)、本(ben)設備采用負高壓制(zhi))和陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積(ji)在相應(ying)的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)，通過設備陰陽極(ji)(ji)振(zhen)打(da)系統的(de)(de)(de)振(zhen)打(da)，使(shi)(shi)沉(chen)積(ji)在陰陽電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)(shang)的(de)(de)(de)粉塵(chen)振(zhen)落(luo)，進人(ren)集灰斗 通過排(pai)灰裝(zhuang)置(zhi)放出(chu)，回收(shou)有物料，被)凈(jing)(jing)化(hua)的(de)(de)(de)氣(qi)(qi)(qi)(qi)體(ti)排(pai)入大(da)氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)(de)工作原(yuan)理(li)是(shi)利用(yong)高壓(ya)(ya)電(dian)(dian)場(chang)使煙(yan)(yan)氣(qi)發生電(dian)(dian)離，氣(qi)流(liu)中的(de)(de)(de)粉塵(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場(chang)作用(yong)下與氣(qi)流(liu)分(fen)離。負極(ji)(ji)(ji)由不同(tong)斷面形(xing)狀(zhuang)的(de)(de)(de)金(jin)屬導(dao)線(xian)制成(cheng)(cheng)，叫放(fang)電(dian)(dian)電(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由不同(tong)幾(ji)何形(xing)狀(zhuang)的(de)(de)(de)金(jin)屬板制成(cheng)(cheng)，叫集塵(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)。靜電(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)(de)(de)性(xing)(xing)能受(shou)粉塵(chen)(chen)性(xing)(xing)質、設備(bei)構造和(he)煙(yan)(yan)氣(qi)流(liu)速等三個因(yin)素的(de)(de)(de)影(ying)響(xiang)。粉塵(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)阻是(shi)評(ping)價導(dao)電(dian)(dian)性(xing)(xing)的(de)(de)(de)指(zhi)標，它(ta)對除(chu)塵(chen)(chen)效(xiao)(xiao)率(lv)有直接(jie)的(de)(de)(de)影(ying)響(xiang)。比(bi)電(dian)(dian)阻過低，塵(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)上，致(zhi)使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)阻過高，到達集塵(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)荷不易放(fang)出，在(zai)塵(chen)(chen)層(ceng)之間形(xing)成(cheng)(cheng)電(dian)(dian)壓(ya)(ya)梯度會產生局部(bu)擊穿(chuan)和(he)放(fang)電(dian)(dian)現(xian)象。這些情況(kuang)都會造成(cheng)(cheng)除(chu)塵(chen)(chen)效(xiao)(xiao)率(lv)下降。

電除塵(chen)器的(de)基本原(yuan)理是利用電力捕集(ji)煙氣中的(de)粉(fen)塵(chen)，主要(yao)包括以下四個(ge)相(xiang)互(hu)有關的(de)物理過程: (1) 氣體(ti)的(de)電離。(2) 粉(fen)塵(chen)的(de)荷電。(3) 荷電粉(fen)塵(chen)向電極(ji)移動。(4) 荷電粉(fen)塵(chen)的(de)捕集(ji)。
