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)(dian)除塵(chen)(chen)(chen)(chen)器(qi)是以靜電(dian)(dian)(dian)(dian)凈化法來收捕廢氣(qi)中的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)，它的(de)(de)(de)凈化工作上(shang)要(yao)是依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和沉淀兩個系統來完成(cheng)的(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)氣(qi)體進人(ren)氣(qi)刺叭時(shi)，含塵(chen)(chen)(chen)(chen)氣(qi)體受到(dao)氣(qi)流(liu)分布板以及(ji)折流(liu)板的(de)(de)(de)調整后(hou)，使(shi)氣(qi)流(liu)能較均勻(yun)地(di)進人(ren)電(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫斷面(mian)擴大的(de)(de)(de)作用(yong)下，氣(qi)流(liu)速(su)度迅速(su)降低，其中有些較重的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒(li)便失去速(su)度而沉降下來。進人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含塵(chen)(chen)(chen)(chen)氣(qi)體由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通(tong)人(ren)高壓直流(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)體電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)氣(qi)體中存在(zai)(zai)大量的(de)(de)(de)電(dian)(dian)(dian)(dian)子和離子，這些電(dian)(dian)(dian)(dian)子和離子與(yu)進人(ren)電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)結(jie)合起來，使(shi)塵(chen)(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)(de)作用(yong)下趨向本設(she)備陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設(she)備采用(yong)負(fu)高壓制(zhi))和陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放出(chu)電(dian)(dian)(dian)(dian)子分別沉積(ji)在(zai)(zai)相(xiang)應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通(tong)過設(she)備陰(yin)陽極(ji)(ji)(ji)振打系統的(de)(de)(de)振打，使(shi)沉積(ji)在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)振落，進人(ren)集灰斗 通(tong)過排(pai)灰裝置放出(chu)，回收有物料，被)凈化的(de)(de)(de)氣(qi)體排(pai)入大氣(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)除塵(chen)器(qi)的(de)(de)(de)工作原理是利用高壓電(dian)(dian)(dian)場使煙氣(qi)(qi)發生電(dian)(dian)(dian)離(li)，氣(qi)(qi)流中的(de)(de)(de)粉(fen)塵(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用下與氣(qi)(qi)流分離(li)。負極(ji)(ji)由不(bu)同(tong)斷面形狀(zhuang)(zhuang)的(de)(de)(de)金(jin)屬導線制(zhi)成，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同(tong)幾何形狀(zhuang)(zhuang)的(de)(de)(de)金(jin)屬板(ban)制(zhi)成，叫(jiao)集(ji)塵(chen)電(dian)(dian)(dian)極(ji)(ji)。靜(jing)電(dian)(dian)(dian)除塵(chen)器(qi)的(de)(de)(de)性能受粉(fen)塵(chen)性質、設備構造和煙氣(qi)(qi)流速等(deng)三個因素的(de)(de)(de)影(ying)響。粉(fen)塵(chen)的(de)(de)(de)比電(dian)(dian)(dian)阻(zu)(zu)是評價導電(dian)(dian)(dian)性的(de)(de)(de)指標(biao)，它對除塵(chen)效率有直接的(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)粒難以保(bao)持在集(ji)塵(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使其(qi)重返(fan)氣(qi)(qi)流。比電(dian)(dian)(dian)阻(zu)(zu)過高，到達集(ji)塵(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)粒電(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)層之間形成電(dian)(dian)(dian)壓梯度會(hui)產生局部擊(ji)穿和放電(dian)(dian)(dian)現象。這些情況(kuang)都會(hui)造成除塵(chen)效率下降。

電(dian)(dian)除塵(chen)(chen)器的(de)基(ji)本原(yuan)理是利用電(dian)(dian)力捕集(ji)煙氣中的(de)粉塵(chen)(chen)，主要包括以下四個相互(hu)有關的(de)物理過程: (1) 氣體(ti)的(de)電(dian)(dian)離(li)。(2) 粉塵(chen)(chen)的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵(chen)(chen)向(xiang)電(dian)(dian)極(ji)移動。(4) 荷(he)電(dian)(dian)粉塵(chen)(chen)的(de)捕集(ji)。
