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)(chen)(chen)器(qi)是(shi)以(yi)靜電(dian)(dian)(dian)凈化法來收(shou)捕廢氣(qi)中(zhong)(zhong)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)(de)(de)(de)(de)凈化工作(zuo)(zuo)上(shang)要是(shi)依靠電(dian)(dian)(dian)暈極(ji)(ji)和沉(chen)(chen)(chen)淀兩個系(xi)統(tong)來完成的(de)(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)(chen)氣(qi)體(ti)進人(ren)(ren)氣(qi)刺叭時，含(han)塵(chen)(chen)(chen)氣(qi)體(ti)受(shou)到氣(qi)流(liu)分(fen)布板(ban)以(yi)及折流(liu)板(ban)的(de)(de)(de)(de)(de)(de)調整后，使(shi)氣(qi)流(liu)能較均勻地進人(ren)(ren)電(dian)(dian)(dian)場。在橫斷面擴大(da)的(de)(de)(de)(de)(de)(de)作(zuo)(zuo)用(yong)下，氣(qi)流(liu)速度迅速降(jiang)低，其中(zhong)(zhong)有些較重的(de)(de)(de)(de)(de)(de)塵(chen)(chen)(chen)粒(li)便(bian)失去速度而沉(chen)(chen)(chen)降(jiang)下來。進人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)暈極(ji)(ji)通人(ren)(ren)高(gao)(gao)壓(ya)直流(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈極(ji)(ji)附近產生電(dian)(dian)(dian)暈現象，使(shi)氣(qi)體(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)(de)(de)氣(qi)體(ti)中(zhong)(zhong)存(cun)在大(da)量的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些電(dian)(dian)(dian)子(zi)和離(li)子(zi)與進人(ren)(ren)電(dian)(dian)(dian)場的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)結(jie)合(he)起來，使(shi)塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在電(dian)(dian)(dian)場力(li)的(de)(de)(de)(de)(de)(de)作(zuo)(zuo)用(yong)下趨向本(ben)設(she)備陽(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設(she)備采用(yong)負高(gao)(gao)壓(ya)制(zhi))和陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子(zi)分(fen)別(bie)沉(chen)(chen)(chen)積(ji)在相應(ying)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)上(shang)，通過(guo)設(she)備陰(yin)陽(yang)極(ji)(ji)振(zhen)(zhen)打系(xi)統(tong)的(de)(de)(de)(de)(de)(de)振(zhen)(zhen)打，使(shi)沉(chen)(chen)(chen)積(ji)在陰(yin)陽(yang)電(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)(de)(de)(de)粉塵(chen)(chen)(chen)振(zhen)(zhen)落(luo)，進人(ren)(ren)集灰(hui)斗 通過(guo)排灰(hui)裝置(zhi)放出，回收(shou)有物料，被)凈化的(de)(de)(de)(de)(de)(de)氣(qi)體(ti)排入大(da)氣(qi)。

工作原理

靜(jing)(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)(de)(de)工作(zuo)原理是利用高(gao)壓電(dian)(dian)(dian)(dian)場(chang)使煙氣發(fa)生電(dian)(dian)(dian)(dian)離(li)，氣流(liu)(liu)中的(de)(de)(de)(de)(de)粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場(chang)作(zuo)用下(xia)與氣流(liu)(liu)分離(li)。負極由(you)不(bu)同(tong)(tong)斷(duan)面形(xing)狀(zhuang)的(de)(de)(de)(de)(de)金(jin)屬導線制(zhi)成，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由(you)不(bu)同(tong)(tong)幾(ji)何(he)形(xing)狀(zhuang)的(de)(de)(de)(de)(de)金(jin)屬板制(zhi)成，叫集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極。靜(jing)(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)(de)(de)(de)性能受粉(fen)塵(chen)(chen)性質、設(she)備構造和(he)(he)煙氣流(liu)(liu)速等(deng)三個因素(su)的(de)(de)(de)(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)(de)(de)(de)比電(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)性的(de)(de)(de)(de)(de)指標，它對除塵(chen)(chen)效(xiao)率有直接(jie)的(de)(de)(de)(de)(de)影響。比電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極上(shang)，致使其重返氣流(liu)(liu)。比電(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到達(da)集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)(de)(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不(bu)易放出，在塵(chen)(chen)層(ceng)之間(jian)形(xing)成電(dian)(dian)(dian)(dian)壓梯(ti)度會產(chan)生局部擊穿和(he)(he)放電(dian)(dian)(dian)(dian)現象。這些情況(kuang)都會造成除塵(chen)(chen)效(xiao)率下(xia)降。

電(dian)(dian)(dian)(dian)除塵(chen)器的(de)基本原理(li)是(shi)利用電(dian)(dian)(dian)(dian)力捕集煙(yan)氣(qi)中的(de)粉(fen)塵(chen)，主要包括以下四個相互有關的(de)物理(li)過程: (1) 氣(qi)體的(de)電(dian)(dian)(dian)(dian)離。(2) 粉(fen)塵(chen)的(de)荷電(dian)(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)(dian)粉(fen)塵(chen)的(de)捕集。
