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(shi)靜電(dian)除塵(chen)(chen)(chen)器是以靜電(dian)凈(jing)化(hua)法來(lai)(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)(de)粉塵(chen)(chen)(chen)，它(ta)的(de)(de)(de)凈(jing)化(hua)工作(zuo)(zuo)上要是依(yi)靠電(dian)暈極(ji)(ji)和(he)沉淀(dian)兩個系統(tong)來(lai)(lai)完成的(de)(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)進(jin)(jin)人(ren)(ren)氣(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)(liu)分布(bu)板以及折流(liu)(liu)板的(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)流(liu)(liu)能較均勻地進(jin)(jin)人(ren)(ren)電(dian)場。在(zai)(zai)橫(heng)斷(duan)面擴大的(de)(de)(de)作(zuo)(zuo)用(yong)(yong)下(xia)，氣(qi)(qi)(qi)流(liu)(liu)速度迅速降低，其中有些較重的(de)(de)(de)塵(chen)(chen)(chen)粒便(bian)失去速度而沉降下(xia)來(lai)(lai)。進(jin)(jin)人(ren)(ren)電(dian)場的(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)暈極(ji)(ji)通人(ren)(ren)高壓直流(liu)(liu)電(dian)，則在(zai)(zai)電(dian)暈極(ji)(ji)附(fu)近產生(sheng)電(dian)暈現(xian)象(xiang)，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)離(li)，電(dian)離(li)后的(de)(de)(de)氣(qi)(qi)(qi)體(ti)中存在(zai)(zai)大量的(de)(de)(de)電(dian)子(zi)和(he)離(li)子(zi)，這些電(dian)子(zi)和(he)離(li)子(zi)與進(jin)(jin)人(ren)(ren)電(dian)場的(de)(de)(de)粉塵(chen)(chen)(chen)結合起來(lai)(lai)，使(shi)塵(chen)(chen)(chen)粒帶(dai)電(dian)，帶(dai)電(dian)塵(chen)(chen)(chen)粒在(zai)(zai)電(dian)場力的(de)(de)(de)作(zuo)(zuo)用(yong)(yong)下(xia)趨向(xiang)本設備陽(yang)極(ji)(ji)(正極(ji)(ji)、本設備采用(yong)(yong)負高壓制)和(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出(chu)電(dian)子(zi)分別沉積(ji)在(zai)(zai)相應的(de)(de)(de)電(dian)極(ji)(ji)上，通過(guo)設備陰(yin)陽(yang)極(ji)(ji)振打系統(tong)的(de)(de)(de)振打，使(shi)沉積(ji)在(zai)(zai)陰(yin)陽(yang)電(dian)極(ji)(ji)上的(de)(de)(de)粉塵(chen)(chen)(chen)振落，進(jin)(jin)人(ren)(ren)集灰(hui)斗(dou) 通過(guo)排灰(hui)裝置放出(chu)，回收有物料(liao)，被)凈(jing)化(hua)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)排入(ru)大氣(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的工作(zuo)原理(li)是(shi)利(li)用高壓(ya)(ya)電(dian)(dian)(dian)(dian)場(chang)使(shi)煙(yan)氣(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)流中的粉(fen)塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣(qi)流分離。負極由(you)(you)不(bu)同(tong)斷面形(xing)狀的金屬導線制(zhi)成，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由(you)(you)不(bu)同(tong)幾何形(xing)狀的金屬板(ban)制(zhi)成，叫集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)器的性能受粉(fen)塵(chen)(chen)(chen)(chen)(chen)性質、設備構造和(he)煙(yan)氣(qi)流速等三(san)個因素的影響(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)(chen)的比(bi)電(dian)(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)(dian)性的指(zhi)標，它(ta)對除塵(chen)(chen)(chen)(chen)(chen)效(xiao)率有直接的影響(xiang)。比(bi)電(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)(chen)(chen)粒難以保(bao)持在(zai)(zai)集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上，致使(shi)其重返氣(qi)流。比(bi)電(dian)(dian)(dian)(dian)阻過(guo)高，到達集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不(bu)易放出，在(zai)(zai)塵(chen)(chen)(chen)(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)(dian)壓(ya)(ya)梯(ti)度會產(chan)生局部擊穿和(he)放電(dian)(dian)(dian)(dian)現象。這些情況都會造成除塵(chen)(chen)(chen)(chen)(chen)效(xiao)率下降。

電(dian)(dian)除塵器的(de)基本原(yuan)理(li)(li)是(shi)利用電(dian)(dian)力捕(bu)集(ji)煙氣中的(de)粉塵，主(zhu)要包(bao)括以(yi)下四個(ge)相(xiang)互有關的(de)物理(li)(li)過程(cheng): (1) 氣體(ti)的(de)電(dian)(dian)離(li)。(2) 粉塵的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉塵向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉塵的(de)捕(bu)集(ji)。
