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)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器是以靜(jing)電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來收捕(bu)廢氣(qi)(qi)中(zhong)的(de)粉(fen)塵(chen)(chen)，它的(de)凈(jing)化(hua)工作上(shang)要(yao)是依(yi)靠電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)和(he)(he)沉(chen)淀(dian)兩個系統(tong)(tong)來完成的(de)，當含塵(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)進(jin)(jin)人(ren)氣(qi)(qi)刺叭(ba)時，含塵(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)受到(dao)氣(qi)(qi)流分布(bu)板以及折流板的(de)調整后，使(shi)(shi)(shi)氣(qi)(qi)流能(neng)較均勻地進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫(heng)斷面擴大的(de)作用(yong)下(xia)(xia)(xia)，氣(qi)(qi)流速度(du)迅速降低(di)，其中(zhong)有(you)些較重的(de)塵(chen)(chen)粒便失去速度(du)而沉(chen)降下(xia)(xia)(xia)來。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)含塵(chen)(chen)氣(qi)(qi)體(ti)(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)通(tong)人(ren)高壓(ya)直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)(shi)(shi)氣(qi)(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后的(de)氣(qi)(qi)體(ti)(ti)(ti)中(zhong)存(cun)在(zai)(zai)大量的(de)電(dian)(dian)(dian)(dian)(dian)子和(he)(he)離(li)子，這些電(dian)(dian)(dian)(dian)(dian)子和(he)(he)離(li)子與進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)粉(fen)塵(chen)(chen)結(jie)合起來，使(shi)(shi)(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)作用(yong)下(xia)(xia)(xia)趨向本設備陽(yang)極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備采用(yong)負(fu)高壓(ya)制)和(he)(he)陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋(shi)放(fang)出電(dian)(dian)(dian)(dian)(dian)子分別沉(chen)積在(zai)(zai)相應的(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通(tong)過設備陰(yin)陽(yang)極(ji)(ji)(ji)振打系統(tong)(tong)的(de)振打，使(shi)(shi)(shi)沉(chen)積在(zai)(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)粉(fen)塵(chen)(chen)振落，進(jin)(jin)人(ren)集灰斗 通(tong)過排(pai)灰裝(zhuang)置放(fang)出，回收有(you)物料，被(bei))凈(jing)化(hua)的(de)氣(qi)(qi)體(ti)(ti)(ti)排(pai)入大氣(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)工作原理是利用(yong)(yong)高壓(ya)(ya)電(dian)(dian)(dian)場使煙(yan)氣發生電(dian)(dian)(dian)離，氣流(liu)中的(de)(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用(yong)(yong)下(xia)與(yu)氣流(liu)分離。負極(ji)由不同斷面形(xing)狀的(de)(de)金屬(shu)導線制成(cheng)(cheng)，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不同幾(ji)何形(xing)狀的(de)(de)金屬(shu)板制成(cheng)(cheng)，叫集塵(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)性能受(shou)粉(fen)塵(chen)(chen)性質(zhi)、設備構造和(he)煙(yan)氣流(liu)速等三個因素的(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)比電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性的(de)(de)指標，它對(dui)除塵(chen)(chen)效(xiao)率有直接的(de)(de)影響。比電(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)粒(li)難以保持在集塵(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其重返(fan)氣流(liu)。比電(dian)(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒(li)電(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)層之間形(xing)成(cheng)(cheng)電(dian)(dian)(dian)壓(ya)(ya)梯(ti)度會產生局部擊穿和(he)放電(dian)(dian)(dian)現象(xiang)。這些情況都會造成(cheng)(cheng)除塵(chen)(chen)效(xiao)率下(xia)降(jiang)。

電(dian)除塵器(qi)的(de)基本原(yuan)理(li)是利(li)用電(dian)力捕集煙氣(qi)中的(de)粉塵，主(zhu)要(yao)包括以下四個相(xiang)互有(you)關(guan)的(de)物理(li)過程(cheng): (1) 氣(qi)體的(de)電(dian)離。(2) 粉塵的(de)荷(he)(he)(he)電(dian)。(3) 荷(he)(he)(he)電(dian)粉塵向電(dian)極移動。(4) 荷(he)(he)(he)電(dian)粉塵的(de)捕集。
