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)(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈化法(fa)來收捕廢(fei)氣(qi)中的(de)(de)(de)(de)粉塵(chen)，它的(de)(de)(de)(de)凈化工作(zuo)上(shang)要(yao)是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉(chen)淀兩個系統來完成的(de)(de)(de)(de)，當含(han)(han)塵(chen)氣(qi)體(ti)進人(ren)氣(qi)刺叭時，含(han)(han)塵(chen)氣(qi)體(ti)受到氣(qi)流(liu)(liu)分布板以及折流(liu)(liu)板的(de)(de)(de)(de)調整后(hou)，使(shi)氣(qi)流(liu)(liu)能較均勻地(di)進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面擴大的(de)(de)(de)(de)作(zuo)用下，氣(qi)流(liu)(liu)速度(du)迅速降低，其(qi)中有些(xie)較重的(de)(de)(de)(de)塵(chen)粒(li)便失去速度(du)而(er)沉(chen)降下來。進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含(han)(han)塵(chen)氣(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通(tong)人(ren)高壓直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附近(jin)產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)氣(qi)體(ti)中存在(zai)大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉塵(chen)結(jie)合起來，使(shi)塵(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)粒(li)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)(de)作(zuo)用下趨向本(ben)設備陽(yang)(yang)(yang)極(ji)(正極(ji)、本(ben)設備采用負高壓制)和陰(yin)(yin)極(ji)(負極(ji)) ， 釋(shi)放出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積(ji)(ji)在(zai)相(xiang)應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通(tong)過設備陰(yin)(yin)陽(yang)(yang)(yang)極(ji)振(zhen)打(da)系統的(de)(de)(de)(de)振(zhen)打(da)，使(shi)沉(chen)積(ji)(ji)在(zai)陰(yin)(yin)陽(yang)(yang)(yang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)粉塵(chen)振(zhen)落，進人(ren)集(ji)灰(hui)斗(dou) 通(tong)過排(pai)灰(hui)裝置放出(chu)，回收有物料，被)凈化的(de)(de)(de)(de)氣(qi)體(ti)排(pai)入大氣(qi)。

工作原理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)(de)工作(zuo)原理是利(li)用高壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣流(liu)分離。負極由不同斷面形(xing)狀(zhuang)的(de)(de)(de)金屬(shu)導(dao)線(xian)制成(cheng)(cheng)，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由不同幾何形(xing)狀(zhuang)的(de)(de)(de)金屬(shu)板制成(cheng)(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)(de)性(xing)能受粉(fen)(fen)塵(chen)(chen)性(xing)質、設備(bei)構造和煙氣流(liu)速等三個因素的(de)(de)(de)影(ying)響(xiang)。粉(fen)(fen)塵(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價(jia)導(dao)電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指(zhi)標，它對(dui)除塵(chen)(chen)效率有直接的(de)(de)(de)影(ying)響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以(yi)保持(chi)在(zai)(zai)集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使其重(zhong)返(fan)氣流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易(yi)放出，在(zai)(zai)塵(chen)(chen)層(ceng)之間形(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)梯度(du)會(hui)產生(sheng)局部(bu)擊穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情(qing)況(kuang)都會(hui)造成(cheng)(cheng)除塵(chen)(chen)效率下降。

電(dian)(dian)除塵(chen)器的(de)基本原理(li)是(shi)利用電(dian)(dian)力捕集煙氣中的(de)粉(fen)塵(chen)，主要(yao)包括以(yi)下四個(ge)相(xiang)互有關(guan)的(de)物理(li)過程: (1) 氣體(ti)的(de)電(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動。(4) 荷電(dian)(dian)粉(fen)塵(chen)的(de)捕集。
