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)器是以(yi)靜電(dian)(dian)(dian)凈化法來(lai)(lai)收捕廢(fei)氣(qi)(qi)中(zhong)的(de)(de)(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)(de)(de)凈化工作上要是依(yi)靠電(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)(he)沉淀兩個系統來(lai)(lai)完成的(de)(de)(de)(de)(de)，當(dang)含(han)塵(chen)(chen)氣(qi)(qi)體進(jin)(jin)人(ren)(ren)氣(qi)(qi)刺(ci)叭(ba)時，含(han)塵(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)分布(bu)板以(yi)及折流(liu)板的(de)(de)(de)(de)(de)調整(zheng)后，使氣(qi)(qi)流(liu)能較均勻地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)。在(zai)(zai)(zai)(zai)橫斷面擴大的(de)(de)(de)(de)(de)作用(yong)下，氣(qi)(qi)流(liu)速(su)度迅速(su)降(jiang)(jiang)低，其中(zhong)有些(xie)較重的(de)(de)(de)(de)(de)塵(chen)(chen)粒便失(shi)去速(su)度而沉降(jiang)(jiang)下來(lai)(lai)。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體由于電(dian)(dian)(dian)暈極(ji)(ji)(ji)通(tong)人(ren)(ren)高(gao)壓(ya)直流(liu)電(dian)(dian)(dian)，則在(zai)(zai)(zai)(zai)電(dian)(dian)(dian)暈極(ji)(ji)(ji)附(fu)近(jin)產生(sheng)電(dian)(dian)(dian)暈現象(xiang)，使氣(qi)(qi)體電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)(de)(de)(de)氣(qi)(qi)體中(zhong)存在(zai)(zai)(zai)(zai)大量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)子和(he)(he)離子，這些(xie)電(dian)(dian)(dian)子和(he)(he)離子與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)(de)粉塵(chen)(chen)結合起來(lai)(lai)，使塵(chen)(chen)粒帶(dai)(dai)電(dian)(dian)(dian)，帶(dai)(dai)電(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)(zai)(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)(de)作用(yong)下趨(qu)向本設備陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備采用(yong)負高(gao)壓(ya)制)和(he)(he)陰極(ji)(ji)(ji)(負極(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)子分別沉積在(zai)(zai)(zai)(zai)相應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)上，通(tong)過(guo)設備陰陽極(ji)(ji)(ji)振(zhen)打系統的(de)(de)(de)(de)(de)振(zhen)打，使沉積在(zai)(zai)(zai)(zai)陰陽電(dian)(dian)(dian)極(ji)(ji)(ji)上的(de)(de)(de)(de)(de)粉塵(chen)(chen)振(zhen)落，進(jin)(jin)人(ren)(ren)集灰(hui)斗 通(tong)過(guo)排(pai)灰(hui)裝置放出，回收有物料，被)凈化的(de)(de)(de)(de)(de)氣(qi)(qi)體排(pai)入(ru)大氣(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)工作(zuo)原理是利(li)用(yong)高壓電(dian)(dian)(dian)(dian)(dian)場使煙(yan)氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流(liu)中的(de)(de)(de)(de)粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場作(zuo)用(yong)下與(yu)氣(qi)(qi)流(liu)分離(li)。負極(ji)由不(bu)同(tong)斷(duan)面形(xing)(xing)狀的(de)(de)(de)(de)金(jin)屬(shu)導線制成，叫放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同(tong)幾何形(xing)(xing)狀的(de)(de)(de)(de)金(jin)屬(shu)板制成，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器(qi)的(de)(de)(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)質、設備構(gou)造和煙(yan)氣(qi)(qi)流(liu)速等三個因(yin)素(su)的(de)(de)(de)(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)的(de)(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)(de)指標(biao)，它對除塵(chen)(chen)(chen)效(xiao)率有直接(jie)的(de)(de)(de)(de)影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒難以保持(chi)在(zai)(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致(zhi)使其(qi)重返氣(qi)(qi)流(liu)。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過(guo)高，到(dao)達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易放(fang)出，在(zai)(zai)塵(chen)(chen)(chen)層之間形(xing)(xing)成電(dian)(dian)(dian)(dian)(dian)壓梯度會產(chan)生(sheng)局部擊(ji)穿和放(fang)電(dian)(dian)(dian)(dian)(dian)現象。這些情(qing)況(kuang)都會造成除塵(chen)(chen)(chen)效(xiao)率下降(jiang)。

電(dian)除塵(chen)器的(de)基本原理(li)是利用(yong)電(dian)力(li)捕集煙氣中的(de)粉塵(chen)，主要包括以下四(si)個相(xiang)互有(you)關的(de)物(wu)理(li)過程: (1) 氣體的(de)電(dian)離。(2) 粉塵(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉塵(chen)向電(dian)極移動。(4) 荷(he)電(dian)粉塵(chen)的(de)捕集。
