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)除塵(chen)(chen)器是(shi)以(yi)靜電(dian)(dian)凈(jing)化(hua)(hua)法來收捕廢氣(qi)中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)，它的(de)(de)(de)凈(jing)化(hua)(hua)工作上(shang)(shang)(shang)要(yao)是(shi)依靠(kao)電(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)和(he)沉淀兩個系統(tong)來完成的(de)(de)(de)，當含塵(chen)(chen)氣(qi)體(ti)(ti)(ti)進人(ren)氣(qi)刺叭時，含塵(chen)(chen)氣(qi)體(ti)(ti)(ti)受到氣(qi)流(liu)分布(bu)板(ban)以(yi)及(ji)折流(liu)板(ban)的(de)(de)(de)調整后，使(shi)氣(qi)流(liu)能較均勻地進人(ren)電(dian)(dian)場(chang)。在(zai)(zai)橫斷面(mian)擴(kuo)大的(de)(de)(de)作用下，氣(qi)流(liu)速(su)度迅速(su)降低，其中有(you)些較重的(de)(de)(de)塵(chen)(chen)粒(li)便失(shi)去(qu)速(su)度而沉降下來。進人(ren)電(dian)(dian)場(chang)的(de)(de)(de)含塵(chen)(chen)氣(qi)體(ti)(ti)(ti)由于電(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)通人(ren)高(gao)壓(ya)直流(liu)電(dian)(dian)，則(ze)在(zai)(zai)電(dian)(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)暈(yun)(yun)現象，使(shi)氣(qi)體(ti)(ti)(ti)電(dian)(dian)離(li)，電(dian)(dian)離(li)后的(de)(de)(de)氣(qi)體(ti)(ti)(ti)中存在(zai)(zai)大量的(de)(de)(de)電(dian)(dian)子和(he)離(li)子，這些電(dian)(dian)子和(he)離(li)子與進人(ren)電(dian)(dian)場(chang)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)結合起來，使(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)場(chang)力的(de)(de)(de)作用下趨向(xiang)本設備(bei)(bei)陽(yang)極(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)、本設備(bei)(bei)采用負高(gao)壓(ya)制)和(he)陰極(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)子分別沉積在(zai)(zai)相應的(de)(de)(de)電(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)(shang)(shang)，通過設備(bei)(bei)陰陽(yang)極(ji)(ji)(ji)(ji)振打系統(tong)的(de)(de)(de)振打，使(shi)沉積在(zai)(zai)陰陽(yang)電(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)(shang)(shang)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)振落(luo)，進人(ren)集灰斗 通過排灰裝置放出，回收有(you)物料，被)凈(jing)化(hua)(hua)的(de)(de)(de)氣(qi)體(ti)(ti)(ti)排入大氣(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)工(gong)作原理是利用(yong)(yong)高(gao)壓電(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)(qi)發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流中的(de)(de)(de)粉塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作用(yong)(yong)下(xia)與氣(qi)(qi)流分(fen)離(li)。負極(ji)由(you)不(bu)(bu)同(tong)斷面形(xing)狀(zhuang)的(de)(de)(de)金屬(shu)導線制(zhi)成(cheng)(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不(bu)(bu)同(tong)幾(ji)何形(xing)狀(zhuang)的(de)(de)(de)金屬(shu)板制(zhi)成(cheng)(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)(de)性能受粉塵(chen)(chen)(chen)性質、設(she)備構造(zao)和煙氣(qi)(qi)流速等三(san)個因素的(de)(de)(de)影響。粉塵(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)(dian)(dian)性的(de)(de)(de)指(zhi)標，它對除(chu)塵(chen)(chen)(chen)效率有直接的(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)(guo)低，塵(chen)(chen)(chen)粒難(nan)以(yi)保(bao)持在集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重(zhong)返氣(qi)(qi)流。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)(guo)高(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)(bu)易(yi)放(fang)出(chu)，在塵(chen)(chen)(chen)層之間形(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿(chuan)和放(fang)電(dian)(dian)(dian)(dian)(dian)現(xian)象。這(zhe)些情況都會造(zao)成(cheng)(cheng)除(chu)塵(chen)(chen)(chen)效率下(xia)降。

電除塵器的(de)基本原(yuan)理(li)是利用電力捕集煙氣(qi)(qi)中的(de)粉塵，主要包括以(yi)下四個相互有關的(de)物理(li)過(guo)程: (1) 氣(qi)(qi)體的(de)電離(li)。(2) 粉塵的(de)荷(he)電。(3) 荷(he)電粉塵向(xiang)電極(ji)移動。(4) 荷(he)電粉塵的(de)捕集。
