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)器是以靜電(dian)(dian)(dian)凈化(hua)法來收捕廢氣(qi)(qi)中的(de)粉塵(chen)(chen)，它(ta)的(de)凈化(hua)工作上(shang)要(yao)是依靠電(dian)(dian)(dian)暈極(ji)和(he)沉(chen)淀兩個系統(tong)來完成的(de)，當含塵(chen)(chen)氣(qi)(qi)體進人(ren)(ren)氣(qi)(qi)刺叭時，含塵(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)分布板(ban)以及折流(liu)板(ban)的(de)調整后(hou)，使(shi)氣(qi)(qi)流(liu)能(neng)較均勻地進人(ren)(ren)電(dian)(dian)(dian)場(chang)。在橫斷面擴大的(de)作用(yong)下(xia)，氣(qi)(qi)流(liu)速(su)度(du)迅速(su)降(jiang)低(di)，其(qi)中有些較重的(de)塵(chen)(chen)粒(li)便失(shi)去速(su)度(du)而(er)沉(chen)降(jiang)下(xia)來。進人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)含塵(chen)(chen)氣(qi)(qi)體由(you)于電(dian)(dian)(dian)暈極(ji)通人(ren)(ren)高壓直(zhi)流(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈極(ji)附近產生(sheng)電(dian)(dian)(dian)暈現象，使(shi)氣(qi)(qi)體電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后(hou)的(de)氣(qi)(qi)體中存在大量的(de)電(dian)(dian)(dian)子和(he)離(li)子，這(zhe)些電(dian)(dian)(dian)子和(he)離(li)子與進人(ren)(ren)電(dian)(dian)(dian)場(chang)的(de)粉塵(chen)(chen)結合起來，使(shi)塵(chen)(chen)粒(li)帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)粒(li)在電(dian)(dian)(dian)場(chang)力(li)的(de)作用(yong)下(xia)趨向本設備陽(yang)極(ji)(正極(ji)、本設備采用(yong)負(fu)高壓制)和(he)陰(yin)極(ji)(負(fu)極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子分別沉(chen)積在相應的(de)電(dian)(dian)(dian)極(ji)上(shang)，通過設備陰(yin)陽(yang)極(ji)振(zhen)打(da)系統(tong)的(de)振(zhen)打(da)，使(shi)沉(chen)積在陰(yin)陽(yang)電(dian)(dian)(dian)極(ji)上(shang)的(de)粉塵(chen)(chen)振(zhen)落，進人(ren)(ren)集灰(hui)(hui)斗 通過排灰(hui)(hui)裝置(zhi)放(fang)出，回收有物料，被)凈化(hua)的(de)氣(qi)(qi)體排入大氣(qi)(qi)。

工作(zuo)原(yuan)理

靜(jing)電(dian)(dian)除(chu)塵器的工(gong)作(zuo)原理是(shi)利(li)用(yong)(yong)高壓(ya)電(dian)(dian)場(chang)使(shi)煙(yan)氣發生(sheng)電(dian)(dian)離(li)，氣流中的粉(fen)塵荷電(dian)(dian)在(zai)電(dian)(dian)場(chang)作(zuo)用(yong)(yong)下與(yu)氣流分離(li)。負極(ji)由(you)不同(tong)斷面形狀(zhuang)的金(jin)屬導(dao)線制成，叫放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由(you)不同(tong)幾(ji)何(he)形狀(zhuang)的金(jin)屬板(ban)制成，叫集(ji)塵電(dian)(dian)極(ji)。靜(jing)電(dian)(dian)除(chu)塵器的性能(neng)受粉(fen)塵性質、設備(bei)構造(zao)和(he)煙(yan)氣流速等三個因素的影(ying)(ying)響。粉(fen)塵的比電(dian)(dian)阻是(shi)評價(jia)導(dao)電(dian)(dian)性的指標，它對(dui)除(chu)塵效(xiao)率有直接的影(ying)(ying)響。比電(dian)(dian)阻過(guo)低，塵粒難(nan)以(yi)保持在(zai)集(ji)塵電(dian)(dian)極(ji)上，致使(shi)其(qi)重返(fan)氣流。比電(dian)(dian)阻過(guo)高，到達集(ji)塵電(dian)(dian)極(ji)的塵粒電(dian)(dian)荷不易(yi)放出，在(zai)塵層之間(jian)形成電(dian)(dian)壓(ya)梯度會產生(sheng)局部擊穿和(he)放電(dian)(dian)現象。這些情況都會造(zao)成除(chu)塵效(xiao)率下降。

電(dian)除塵器的(de)基本原理是利(li)用電(dian)力捕(bu)(bu)集(ji)煙氣中(zhong)的(de)粉塵，主要包括以下四個(ge)相互(hu)有(you)關(guan)的(de)物理過程: (1) 氣體(ti)的(de)電(dian)離。(2) 粉塵的(de)荷(he)(he)電(dian)。(3) 荷(he)(he)電(dian)粉塵向(xiang)電(dian)極移動。(4) 荷(he)(he)電(dian)粉塵的(de)捕(bu)(bu)集(ji)。
