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)器(qi)是以靜電(dian)(dian)(dian)凈化(hua)法來(lai)收(shou)捕廢(fei)氣(qi)(qi)(qi)(qi)中的(de)(de)粉塵(chen)，它的(de)(de)凈化(hua)工作(zuo)(zuo)上(shang)要是依靠電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)沉淀兩(liang)個系統(tong)來(lai)完成(cheng)的(de)(de)，當含塵(chen)氣(qi)(qi)(qi)(qi)體(ti)進(jin)人氣(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(liu)分布板(ban)以及折(zhe)流(liu)板(ban)的(de)(de)調整后(hou)，使(shi)氣(qi)(qi)(qi)(qi)流(liu)能較均勻地進(jin)人電(dian)(dian)(dian)場(chang)(chang)。在(zai)橫斷面擴大(da)的(de)(de)作(zuo)(zuo)用下，氣(qi)(qi)(qi)(qi)流(liu)速(su)度迅(xun)速(su)降低，其中有些較重的(de)(de)塵(chen)粒(li)便失去(qu)速(su)度而(er)沉降下來(lai)。進(jin)人電(dian)(dian)(dian)場(chang)(chang)的(de)(de)含塵(chen)氣(qi)(qi)(qi)(qi)體(ti)由(you)于(yu)電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人高壓直流(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近(jin)產(chan)生電(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后(hou)的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)中存在(zai)大(da)量的(de)(de)電(dian)(dian)(dian)子和(he)離(li)子，這些電(dian)(dian)(dian)子和(he)離(li)子與進(jin)人電(dian)(dian)(dian)場(chang)(chang)的(de)(de)粉塵(chen)結合起來(lai)，使(shi)塵(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)粒(li)在(zai)電(dian)(dian)(dian)場(chang)(chang)力的(de)(de)作(zuo)(zuo)用下趨(qu)向(xiang)本設備陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備采用負(fu)高壓制)和(he)陰極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子分別沉積在(zai)相應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通過設備陰陽(yang)極(ji)(ji)(ji)振打系統(tong)的(de)(de)振打，使(shi)沉積在(zai)陰陽(yang)電(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)粉塵(chen)振落(luo)，進(jin)人集灰斗 通過排灰裝置(zhi)放出，回收(shou)有物料，被)凈化(hua)的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)(qi)。

工作原理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的工(gong)作(zuo)原理是(shi)(shi)利(li)用高(gao)壓(ya)(ya)電(dian)(dian)(dian)場使煙氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)離，氣(qi)(qi)流中的粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作(zuo)用下與氣(qi)(qi)流分離。負(fu)極由(you)不同(tong)斷面形(xing)狀的金(jin)屬導(dao)線(xian)制成(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由(you)不同(tong)幾何形(xing)狀的金(jin)屬板(ban)制成(cheng)，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的性(xing)能受粉塵(chen)(chen)(chen)性(xing)質、設備構(gou)造(zao)和(he)煙氣(qi)(qi)流速等三個因素的影響。粉塵(chen)(chen)(chen)的比(bi)(bi)電(dian)(dian)(dian)阻是(shi)(shi)評價導(dao)電(dian)(dian)(dian)性(xing)的指標，它對除(chu)塵(chen)(chen)(chen)效率有(you)直(zhi)接(jie)的影響。比(bi)(bi)電(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)粒難以保持在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極上，致使其(qi)重返(fan)氣(qi)(qi)流。比(bi)(bi)電(dian)(dian)(dian)阻過高(gao)，到達(da)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極的塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易(yi)放(fang)出，在(zai)塵(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)壓(ya)(ya)梯度會(hui)產生(sheng)局部(bu)擊穿和(he)放(fang)電(dian)(dian)(dian)現象(xiang)。這些(xie)情(qing)況都會(hui)造(zao)成(cheng)除(chu)塵(chen)(chen)(chen)效率下降。

電(dian)(dian)(dian)(dian)除塵器的(de)(de)基本原理(li)是利(li)用電(dian)(dian)(dian)(dian)力(li)捕(bu)集煙氣中的(de)(de)粉(fen)塵，主要包括(kuo)以下四(si)個相互有關的(de)(de)物理(li)過程: (1) 氣體的(de)(de)電(dian)(dian)(dian)(dian)離。(2) 粉(fen)塵的(de)(de)荷(he)(he)電(dian)(dian)(dian)(dian)。(3) 荷(he)(he)電(dian)(dian)(dian)(dian)粉(fen)塵向(xiang)電(dian)(dian)(dian)(dian)極(ji)移動。(4) 荷(he)(he)電(dian)(dian)(dian)(dian)粉(fen)塵的(de)(de)捕(bu)集。
