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(jing)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器是以(yi)靜(jing)電(dian)(dian)(dian)凈(jing)化法(fa)來收捕廢氣(qi)(qi)(qi)(qi)(qi)中(zhong)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)，它(ta)的(de)(de)(de)凈(jing)化工作上(shang)要是依靠(kao)電(dian)(dian)(dian)暈(yun)極(ji)和(he)沉淀兩個系統(tong)來完成的(de)(de)(de)，當(dang)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)進人氣(qi)(qi)(qi)(qi)(qi)刺叭時，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)(qi)(qi)流(liu)分布板(ban)以(yi)及折流(liu)板(ban)的(de)(de)(de)調(diao)整后(hou)，使(shi)氣(qi)(qi)(qi)(qi)(qi)流(liu)能較(jiao)均勻(yun)地進人電(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫(heng)斷(duan)面擴大的(de)(de)(de)作用(yong)下(xia)，氣(qi)(qi)(qi)(qi)(qi)流(liu)速度(du)迅速降(jiang)低，其中(zhong)有些較(jiao)重(zhong)的(de)(de)(de)塵(chen)(chen)(chen)粒(li)便(bian)失去(qu)速度(du)而沉降(jiang)下(xia)來。進人電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)暈(yun)極(ji)通(tong)人高(gao)壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈(yun)極(ji)附近(jin)產生電(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)中(zhong)存在(zai)(zai)大量的(de)(de)(de)電(dian)(dian)(dian)子和(he)離(li)子，這些電(dian)(dian)(dian)子和(he)離(li)子與進人電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)結(jie)合(he)起來，使(shi)塵(chen)(chen)(chen)粒(li)帶(dai)電(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)場(chang)(chang)力(li)的(de)(de)(de)作用(yong)下(xia)趨(qu)向(xiang)本(ben)設(she)備陽極(ji)(正極(ji)、本(ben)設(she)備采用(yong)負高(gao)壓(ya)制)和(he)陰極(ji)(負極(ji)) ， 釋放出(chu)電(dian)(dian)(dian)子分別沉積(ji)在(zai)(zai)相(xiang)應的(de)(de)(de)電(dian)(dian)(dian)極(ji)上(shang)，通(tong)過設(she)備陰陽極(ji)振(zhen)打系統(tong)的(de)(de)(de)振(zhen)打，使(shi)沉積(ji)在(zai)(zai)陰陽電(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)振(zhen)落(luo)，進人集灰斗(dou) 通(tong)過排灰裝(zhuang)置放出(chu)，回(hui)收有物(wu)料，被)凈(jing)化的(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)排入大氣(qi)(qi)(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)工作原理(li)是利(li)用高(gao)壓(ya)電(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)發生(sheng)電(dian)(dian)(dian)(dian)離，氣(qi)(qi)流(liu)(liu)中的(de)粉塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場作用下與氣(qi)(qi)流(liu)(liu)分離。負極(ji)由(you)不(bu)同斷(duan)面形(xing)(xing)狀(zhuang)的(de)金屬導線(xian)制(zhi)成，叫(jiao)放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不(bu)同幾(ji)何形(xing)(xing)狀(zhuang)的(de)金屬板(ban)制(zhi)成，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)性能(neng)受粉塵(chen)(chen)(chen)性質、設備構(gou)造和煙氣(qi)(qi)流(liu)(liu)速等三個(ge)因素的(de)影(ying)響。粉塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)阻是評(ping)價(jia)導電(dian)(dian)(dian)(dian)性的(de)指標，它對除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率有(you)直接(jie)的(de)影(ying)響。比電(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使其重返氣(qi)(qi)流(liu)(liu)。比電(dian)(dian)(dian)(dian)阻過(guo)高(gao)，到達(da)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)不(bu)易放出，在(zai)塵(chen)(chen)(chen)層之間(jian)形(xing)(xing)成電(dian)(dian)(dian)(dian)壓(ya)梯度會產生(sheng)局部擊穿和放電(dian)(dian)(dian)(dian)現象。這些(xie)情況(kuang)都會造成除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率下降。

電除塵(chen)器(qi)的(de)基本原(yuan)理是(shi)利(li)用電力捕集煙氣(qi)中(zhong)的(de)粉塵(chen)，主要包括(kuo)以下四個相互有(you)關的(de)物理過程: (1) 氣(qi)體(ti)的(de)電離。(2) 粉塵(chen)的(de)荷(he)電。(3) 荷(he)電粉塵(chen)向電極移動。(4) 荷(he)電粉塵(chen)的(de)捕集。
