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)式靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器是(shi)以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收捕廢(fei)氣(qi)(qi)中(zhong)的(de)(de)粉塵(chen)(chen)，它(ta)的(de)(de)凈(jing)化(hua)工作上(shang)(shang)(shang)要(yao)是(shi)依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)和沉淀兩(liang)個系統來(lai)完成(cheng)的(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)體(ti)進人(ren)(ren)(ren)氣(qi)(qi)刺叭(ba)時(shi)，含(han)塵(chen)(chen)氣(qi)(qi)體(ti)受到氣(qi)(qi)流(liu)(liu)分布板以(yi)及(ji)折流(liu)(liu)板的(de)(de)調整后(hou)，使氣(qi)(qi)流(liu)(liu)能較均勻地進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)橫斷面擴大的(de)(de)作用下，氣(qi)(qi)流(liu)(liu)速(su)度迅速(su)降(jiang)(jiang)低，其中(zhong)有(you)些(xie)較重的(de)(de)塵(chen)(chen)粒便失(shi)去速(su)度而(er)沉降(jiang)(jiang)下來(lai)。進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)通人(ren)(ren)(ren)高(gao)壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)氣(qi)(qi)體(ti)中(zhong)存(cun)在(zai)大量的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)，這(zhe)些(xie)電(dian)(dian)(dian)(dian)(dian)子(zi)和離(li)子(zi)與進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)粉塵(chen)(chen)結合起來(lai)，使塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)作用下趨向本(ben)設備(bei)陽極(ji)(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)(ji)、本(ben)設備(bei)采用負(fu)高(gao)壓制)和陰極(ji)(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)分別沉積在(zai)相應(ying)的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)(shang)(shang)，通過(guo)設備(bei)陰陽極(ji)(ji)(ji)(ji)振(zhen)打(da)系統的(de)(de)振(zhen)打(da)，使沉積在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)上(shang)(shang)(shang)的(de)(de)粉塵(chen)(chen)振(zhen)落，進人(ren)(ren)(ren)集灰斗 通過(guo)排灰裝(zhuang)置放出，回(hui)收有(you)物料，被)凈(jing)化(hua)的(de)(de)氣(qi)(qi)體(ti)排入大氣(qi)(qi)。

工作原理(li)

靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)(de)工作(zuo)原理是(shi)利用高壓電(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣發(fa)生電(dian)(dian)(dian)(dian)(dian)離，氣流(liu)中的(de)(de)(de)粉塵(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)場作(zuo)用下與(yu)氣流(liu)分(fen)離。負極(ji)由(you)不(bu)同(tong)斷面形(xing)狀的(de)(de)(de)金(jin)屬(shu)導線制成(cheng)，叫放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)。正極(ji)由(you)不(bu)同(tong)幾何形(xing)狀的(de)(de)(de)金(jin)屬(shu)板(ban)制成(cheng)，叫集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)器的(de)(de)(de)性(xing)(xing)(xing)能受(shou)粉塵(chen)性(xing)(xing)(xing)質、設備構造和(he)煙氣流(liu)速等三個因素的(de)(de)(de)影(ying)響。粉塵(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)是(shi)評價(jia)導電(dian)(dian)(dian)(dian)(dian)性(xing)(xing)(xing)的(de)(de)(de)指標，它對(dui)除塵(chen)效(xiao)率有(you)直接的(de)(de)(de)影(ying)響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)粒(li)難以保(bao)持在集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣流(liu)。比電(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到(dao)達(da)集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易(yi)放(fang)出(chu)，在塵(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯(ti)度(du)會產(chan)生局部擊穿和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)現(xian)象。這些情(qing)況(kuang)都會造成(cheng)除塵(chen)效(xiao)率下降。

電(dian)除塵(chen)器(qi)的(de)基本原理(li)是利用電(dian)力捕集煙氣中的(de)粉塵(chen)，主要包(bao)括以下(xia)四(si)個相互有(you)關的(de)物理(li)過程: (1) 氣體的(de)電(dian)離(li)。(2) 粉塵(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉塵(chen)向電(dian)極移動。(4) 荷(he)電(dian)粉塵(chen)的(de)捕集。
