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(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是(shi)以靜(jing)電(dian)(dian)(dian)(dian)凈化(hua)法來收捕廢氣(qi)中的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)，它(ta)的(de)(de)(de)(de)(de)凈化(hua)工作(zuo)上要是(shi)依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉(chen)淀兩個系統來完成的(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)進(jin)人氣(qi)刺叭(ba)時，含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)受到氣(qi)流(liu)分布(bu)板以及(ji)折流(liu)板的(de)(de)(de)(de)(de)調整后(hou)，使(shi)(shi)氣(qi)流(liu)能(neng)較均勻(yun)地(di)進(jin)人電(dian)(dian)(dian)(dian)場。在橫斷面擴大的(de)(de)(de)(de)(de)作(zuo)用下，氣(qi)流(liu)速(su)(su)度迅速(su)(su)降低，其中有些較重的(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒便(bian)失去速(su)(su)度而沉(chen)降下來。進(jin)人電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)通(tong)人高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使(shi)(shi)氣(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)(de)(de)氣(qi)體(ti)(ti)(ti)中存(cun)在大量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)(dian)子(zi)和離子(zi)與進(jin)人電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)結(jie)合(he)起來，使(shi)(shi)塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在電(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)作(zuo)用下趨向本(ben)設(she)備(bei)陽(yang)極(ji)(正極(ji)、本(ben)設(she)備(bei)采用負(fu)高壓(ya)制)和陰極(ji)(負(fu)極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)分別(bie)沉(chen)積(ji)在相應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)上，通(tong)過設(she)備(bei)陰陽(yang)極(ji)振打系統的(de)(de)(de)(de)(de)振打，使(shi)(shi)沉(chen)積(ji)在陰陽(yang)電(dian)(dian)(dian)(dian)極(ji)上的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)振落(luo)，進(jin)人集灰斗 通(tong)過排灰裝(zhuang)置放出，回收有物料，被)凈化(hua)的(de)(de)(de)(de)(de)氣(qi)體(ti)(ti)(ti)排入大氣(qi)。

工(gong)作原理

靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)器的工作原理(li)是(shi)利用(yong)高壓電(dian)(dian)(dian)場使煙(yan)氣發生電(dian)(dian)(dian)離，氣流中的粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)場作用(yong)下與氣流分(fen)離。負極(ji)(ji)由(you)不同(tong)斷面形狀的金屬(shu)導線制成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不同(tong)幾何形狀的金屬(shu)板制成，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)除塵(chen)(chen)(chen)器的性能受粉(fen)塵(chen)(chen)(chen)性質、設備構造和煙(yan)氣流速等三個因素的影響(xiang)。粉(fen)塵(chen)(chen)(chen)的比(bi)電(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)性的指標(biao)，它對除塵(chen)(chen)(chen)效(xiao)率(lv)有直接的影響(xiang)。比(bi)電(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒難以保持在(zai)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣流。比(bi)電(dian)(dian)(dian)阻過(guo)高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易放出，在(zai)塵(chen)(chen)(chen)層(ceng)之間(jian)形成電(dian)(dian)(dian)壓梯度會(hui)產生局部擊(ji)穿和放電(dian)(dian)(dian)現象(xiang)。這些(xie)情況都會(hui)造成除塵(chen)(chen)(chen)效(xiao)率(lv)下降。

電(dian)除塵器的(de)基本原理(li)是(shi)利用電(dian)力捕集煙氣中的(de)粉(fen)(fen)塵，主要包括以下四個(ge)相互有關的(de)物理(li)過程: (1) 氣體(ti)的(de)電(dian)離。(2) 粉(fen)(fen)塵的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)(fen)塵向電(dian)極移動。(4) 荷(he)電(dian)粉(fen)(fen)塵的(de)捕集。
