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)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)(dian)凈化法(fa)來收捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)，它的(de)(de)凈化工作上要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)和(he)(he)沉(chen)淀(dian)兩個系(xi)統(tong)來完成的(de)(de)，當(dang)含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進(jin)人(ren)氣(qi)(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流分(fen)布板以及折流板的(de)(de)調整后，使(shi)氣(qi)(qi)(qi)流能較均勻地進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在橫斷面擴大的(de)(de)作用(yong)下，氣(qi)(qi)(qi)流速(su)度(du)迅速(su)降低，其中(zhong)有些較重的(de)(de)塵(chen)(chen)(chen)粒便(bian)失去速(su)度(du)而沉(chen)降下來。進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)通(tong)(tong)人(ren)高壓直(zhi)流電(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現(xian)象，使(shi)氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中(zhong)存(cun)在大量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)(he)離(li)子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)(he)離(li)子(zi)與進(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)(chen)(chen)結合起來，使(shi)塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用(yong)下趨向本(ben)設(she)備陽(yang)極(ji)(正極(ji)、本(ben)設(she)備采用(yong)負高壓制)和(he)(he)陰極(ji)(負極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)積(ji)在相(xiang)應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，通(tong)(tong)過設(she)備陰陽(yang)極(ji)振打系(xi)統(tong)的(de)(de)振打，使(shi)沉(chen)積(ji)在陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)(de)粉(fen)塵(chen)(chen)(chen)振落，進(jin)人(ren)集(ji)灰(hui)斗 通(tong)(tong)過排灰(hui)裝置放(fang)出，回收有物(wu)料，被)凈化的(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)。

工作(zuo)原理

靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)工作原理是利用(yong)高壓電(dian)(dian)(dian)(dian)(dian)場(chang)使煙(yan)氣發(fa)生(sheng)電(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場(chang)作用(yong)下與氣流(liu)分(fen)離。負極由不同斷面形(xing)狀的(de)(de)金(jin)屬導線制(zhi)成，叫放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由不同幾何形(xing)狀的(de)(de)金(jin)屬板制(zhi)成，叫集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)性(xing)(xing)能受粉塵(chen)(chen)性(xing)(xing)質、設備構(gou)造(zao)和煙(yan)氣流(liu)速(su)等三個(ge)因素的(de)(de)影響(xiang)。粉塵(chen)(chen)的(de)(de)比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)性(xing)(xing)的(de)(de)指標(biao)，它對除塵(chen)(chen)效(xiao)率(lv)有直(zhi)接的(de)(de)影響(xiang)。比(bi)(bi)電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以保持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使其(qi)重返氣流(liu)。比(bi)(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)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易(yi)放出，在塵(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部擊(ji)穿和放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都(dou)會造(zao)成除塵(chen)(chen)效(xiao)率(lv)下降。

電(dian)除塵(chen)(chen)器(qi)的基本原理是利用電(dian)力捕(bu)集煙氣(qi)中的粉(fen)塵(chen)(chen)，主要包括以下四個相(xiang)互有(you)關的物理過程: (1) 氣(qi)體的電(dian)離。(2) 粉(fen)塵(chen)(chen)的荷電(dian)。(3) 荷電(dian)粉(fen)塵(chen)(chen)向電(dian)極(ji)移動。(4) 荷電(dian)粉(fen)塵(chen)(chen)的捕(bu)集。
