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)除塵(chen)(chen)器是(shi)(shi)以靜電(dian)凈(jing)(jing)化法來(lai)(lai)收捕廢氣(qi)(qi)中(zhong)的(de)(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)(de)凈(jing)(jing)化工作上(shang)要是(shi)(shi)依靠電(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)(ji)(ji)和沉(chen)淀兩個系統來(lai)(lai)完成的(de)(de)(de)(de)，當含(han)(han)(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)進(jin)人(ren)(ren)氣(qi)(qi)刺(ci)叭時，含(han)(han)(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流分布(bu)板以及折流板的(de)(de)(de)(de)調整后(hou)，使氣(qi)(qi)流能較均勻(yun)地進(jin)人(ren)(ren)電(dian)場。在(zai)橫斷(duan)面擴(kuo)大(da)的(de)(de)(de)(de)作用(yong)下，氣(qi)(qi)流速度迅速降低(di)，其中(zhong)有些較重的(de)(de)(de)(de)塵(chen)(chen)粒(li)(li)便失去速度而沉(chen)降下來(lai)(lai)。進(jin)人(ren)(ren)電(dian)場的(de)(de)(de)(de)含(han)(han)(han)塵(chen)(chen)氣(qi)(qi)體(ti)(ti)由于(yu)電(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)(ji)(ji)通(tong)人(ren)(ren)高(gao)壓(ya)直流電(dian)，則在(zai)電(dian)暈(yun)(yun)極(ji)(ji)(ji)(ji)(ji)(ji)附近(jin)產生電(dian)暈(yun)(yun)現(xian)象，使氣(qi)(qi)體(ti)(ti)電(dian)離，電(dian)離后(hou)的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)中(zhong)存在(zai)大(da)量的(de)(de)(de)(de)電(dian)子和離子，這些電(dian)子和離子與進(jin)人(ren)(ren)電(dian)場的(de)(de)(de)(de)粉塵(chen)(chen)結合起來(lai)(lai)，使塵(chen)(chen)粒(li)(li)帶(dai)(dai)電(dian)，帶(dai)(dai)電(dian)塵(chen)(chen)粒(li)(li)在(zai)電(dian)場力的(de)(de)(de)(de)作用(yong)下趨向本設(she)備陽(yang)極(ji)(ji)(ji)(ji)(ji)(ji)(正極(ji)(ji)(ji)(ji)(ji)(ji)、本設(she)備采用(yong)負高(gao)壓(ya)制)和陰極(ji)(ji)(ji)(ji)(ji)(ji)(負極(ji)(ji)(ji)(ji)(ji)(ji)) ， 釋(shi)放出電(dian)子分別沉(chen)積在(zai)相應的(de)(de)(de)(de)電(dian)極(ji)(ji)(ji)(ji)(ji)(ji)上(shang)，通(tong)過設(she)備陰陽(yang)極(ji)(ji)(ji)(ji)(ji)(ji)振打系統的(de)(de)(de)(de)振打，使沉(chen)積在(zai)陰陽(yang)電(dian)極(ji)(ji)(ji)(ji)(ji)(ji)上(shang)的(de)(de)(de)(de)粉塵(chen)(chen)振落，進(jin)人(ren)(ren)集灰(hui)斗(dou) 通(tong)過排灰(hui)裝置放出，回(hui)收有物料(liao)，被)凈(jing)(jing)化的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)排入大(da)氣(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的(de)工作(zuo)原理(li)是(shi)利(li)用高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)使(shi)煙氣發生(sheng)電(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)粉塵(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣流(liu)分離。負極(ji)(ji)由不同(tong)斷面形(xing)狀的(de)金屬(shu)導線制成，叫放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由不同(tong)幾(ji)何形(xing)狀的(de)金屬(shu)板制成，叫集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的(de)性能(neng)受(shou)粉塵(chen)(chen)(chen)(chen)(chen)性質、設(she)備構造和煙氣流(liu)速(su)等三個(ge)因素的(de)影響。粉塵(chen)(chen)(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評價導電(dian)(dian)(dian)(dian)(dian)性的(de)指(zhi)標，它對除塵(chen)(chen)(chen)(chen)(chen)效率(lv)有直接的(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使(shi)其重返氣流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻(zu)過(guo)高(gao)，到達集塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不易放(fang)(fang)出，在塵(chen)(chen)(chen)(chen)(chen)層(ceng)之(zhi)間形(xing)成電(dian)(dian)(dian)(dian)(dian)壓(ya)梯度(du)會(hui)產生(sheng)局部擊穿和放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會(hui)造成除塵(chen)(chen)(chen)(chen)(chen)效率(lv)下降。

電(dian)除塵器的(de)(de)(de)基本原理(li)是利(li)用電(dian)力捕(bu)集煙氣中(zhong)的(de)(de)(de)粉(fen)塵，主要包括以(yi)下四個相互有關(guan)的(de)(de)(de)物(wu)理(li)過程(cheng): (1) 氣體的(de)(de)(de)電(dian)離(li)。(2) 粉(fen)塵的(de)(de)(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵向電(dian)極移動。(4) 荷(he)電(dian)粉(fen)塵的(de)(de)(de)捕(bu)集。
