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(jing)電(dian)除塵(chen)(chen)器是以靜(jing)電(dian)凈(jing)化(hua)法(fa)來(lai)收捕廢氣(qi)(qi)(qi)中(zhong)的(de)粉塵(chen)(chen)，它的(de)凈(jing)化(hua)工(gong)作上(shang)要是依靠電(dian)暈極(ji)和(he)(he)沉淀兩個系統來(lai)完成的(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)體進(jin)(jin)人氣(qi)(qi)(qi)刺(ci)叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)體受到氣(qi)(qi)(qi)流(liu)分(fen)布板(ban)以及折流(liu)板(ban)的(de)調整后，使(shi)氣(qi)(qi)(qi)流(liu)能較均(jun)勻地(di)進(jin)(jin)人電(dian)場(chang)。在(zai)橫斷(duan)面擴大的(de)作用下(xia)，氣(qi)(qi)(qi)流(liu)速(su)度(du)(du)迅速(su)降(jiang)低，其(qi)中(zhong)有些較重的(de)塵(chen)(chen)粒便(bian)失去速(su)度(du)(du)而沉降(jiang)下(xia)來(lai)。進(jin)(jin)人電(dian)場(chang)的(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)體由(you)于(yu)電(dian)暈極(ji)通(tong)(tong)人高(gao)(gao)壓(ya)直流(liu)電(dian)，則在(zai)電(dian)暈極(ji)附近產生電(dian)暈現象(xiang)，使(shi)氣(qi)(qi)(qi)體電(dian)離，電(dian)離后的(de)氣(qi)(qi)(qi)體中(zhong)存在(zai)大量的(de)電(dian)子和(he)(he)離子，這(zhe)些電(dian)子和(he)(he)離子與進(jin)(jin)人電(dian)場(chang)的(de)粉塵(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)粒帶電(dian)，帶電(dian)塵(chen)(chen)粒在(zai)電(dian)場(chang)力的(de)作用下(xia)趨向本(ben)設備(bei)陽(yang)極(ji)(正極(ji)、本(ben)設備(bei)采(cai)用負高(gao)(gao)壓(ya)制)和(he)(he)陰極(ji)(負極(ji)) ， 釋放出電(dian)子分(fen)別(bie)沉積(ji)在(zai)相(xiang)應的(de)電(dian)極(ji)上(shang)，通(tong)(tong)過(guo)(guo)設備(bei)陰陽(yang)極(ji)振打系統的(de)振打，使(shi)沉積(ji)在(zai)陰陽(yang)電(dian)極(ji)上(shang)的(de)粉塵(chen)(chen)振落，進(jin)(jin)人集灰斗 通(tong)(tong)過(guo)(guo)排灰裝置放出，回收有物料，被)凈(jing)化(hua)的(de)氣(qi)(qi)(qi)體排入(ru)大氣(qi)(qi)(qi)。

工作原理(li)

靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)工作原理是利用(yong)高壓(ya)電(dian)(dian)(dian)場使(shi)(shi)煙(yan)氣(qi)發生(sheng)電(dian)(dian)(dian)離，氣(qi)流中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用(yong)下與氣(qi)流分離。負極(ji)(ji)由不(bu)同(tong)斷面形(xing)狀的(de)金屬導線制成，叫(jiao)放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由不(bu)同(tong)幾何形(xing)狀的(de)金屬板制成，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)性能受粉(fen)塵(chen)(chen)(chen)性質、設(she)備構(gou)造(zao)(zao)和(he)煙(yan)氣(qi)流速等三個因(yin)素的(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)性的(de)指標，它對除(chu)塵(chen)(chen)(chen)效率有直接(jie)的(de)影響。比電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使(shi)(shi)其重返氣(qi)流。比電(dian)(dian)(dian)阻(zu)過高，到(dao)達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易放(fang)(fang)出，在塵(chen)(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)壓(ya)梯度(du)會產生(sheng)局部擊穿和(he)放(fang)(fang)電(dian)(dian)(dian)現象。這些情況都(dou)會造(zao)(zao)成除(chu)塵(chen)(chen)(chen)效率下降。

電(dian)(dian)(dian)(dian)除塵器的(de)基(ji)本原理是(shi)利用電(dian)(dian)(dian)(dian)力捕集煙氣(qi)中的(de)粉(fen)塵，主(zhu)要包括以(yi)下(xia)四個相(xiang)互有關的(de)物理過(guo)程: (1) 氣(qi)體(ti)(ti)的(de)電(dian)(dian)(dian)(dian)離(li)。(2) 粉(fen)塵的(de)荷電(dian)(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)(dian)粉(fen)塵向電(dian)(dian)(dian)(dian)極移(yi)動。(4) 荷電(dian)(dian)(dian)(dian)粉(fen)塵的(de)捕集。
