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(chu)塵(chen)(chen)器(qi)是以(yi)靜電(dian)(dian)(dian)(dian)凈(jing)化(hua)法來(lai)收捕(bu)廢氣(qi)(qi)(qi)(qi)(qi)中的(de)(de)(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)(de)(de)凈(jing)化(hua)工(gong)作(zuo)上(shang)要是依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)和(he)沉淀兩(liang)個(ge)系統來(lai)完(wan)成的(de)(de)(de)(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)進(jin)(jin)人(ren)(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)受到(dao)氣(qi)(qi)(qi)(qi)(qi)流(liu)分(fen)布板以(yi)及折流(liu)板的(de)(de)(de)(de)(de)調整后，使(shi)氣(qi)(qi)(qi)(qi)(qi)流(liu)能(neng)較均勻(yun)地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫斷面擴大的(de)(de)(de)(de)(de)作(zuo)用下(xia)，氣(qi)(qi)(qi)(qi)(qi)流(liu)速(su)度迅速(su)降低，其中有(you)些(xie)較重的(de)(de)(de)(de)(de)塵(chen)(chen)粒(li)便失去速(su)度而沉降下(xia)來(lai)。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)通人(ren)(ren)高壓直(zhi)流(liu)電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)中存在(zai)(zai)大量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子和(he)離(li)子，這些(xie)電(dian)(dian)(dian)(dian)子和(he)離(li)子與進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)(de)(de)粉塵(chen)(chen)結合起來(lai)，使(shi)塵(chen)(chen)粒(li)帶(dai)(dai)電(dian)(dian)(dian)(dian)，帶(dai)(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)粒(li)在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)力(li)的(de)(de)(de)(de)(de)作(zuo)用下(xia)趨向本(ben)(ben)設(she)備陽(yang)(yang)極(ji)(正極(ji)、本(ben)(ben)設(she)備采(cai)用負(fu)高壓制)和(he)陰(yin)(yin)極(ji)(負(fu)極(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)子分(fen)別沉積在(zai)(zai)相應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)上(shang)，通過設(she)備陰(yin)(yin)陽(yang)(yang)極(ji)振打系統的(de)(de)(de)(de)(de)振打，使(shi)沉積在(zai)(zai)陰(yin)(yin)陽(yang)(yang)電(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)(de)(de)粉塵(chen)(chen)振落，進(jin)(jin)人(ren)(ren)集灰斗 通過排灰裝置放出，回收有(you)物料，被)凈(jing)化(hua)的(de)(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)排入(ru)大氣(qi)(qi)(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)除塵(chen)(chen)器(qi)(qi)的(de)工作原理是(shi)利用高(gao)壓(ya)電(dian)(dian)(dian)場(chang)使煙氣發生電(dian)(dian)(dian)離，氣流(liu)中的(de)粉塵(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作用下與氣流(liu)分離。負極(ji)(ji)由(you)不同斷面形(xing)狀(zhuang)的(de)金(jin)屬(shu)導線制成，叫(jiao)放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由(you)不同幾何形(xing)狀(zhuang)的(de)金(jin)屬(shu)板制成，叫(jiao)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)除塵(chen)(chen)器(qi)(qi)的(de)性能受粉塵(chen)(chen)性質、設備構造和(he)煙氣流(liu)速等三個因素的(de)影響(xiang)。粉塵(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)性的(de)指(zhi)標，它(ta)對除塵(chen)(chen)效(xiao)率有(you)直接的(de)影響(xiang)。比(bi)電(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難(nan)以保持在集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣流(liu)。比(bi)電(dian)(dian)(dian)阻過高(gao)，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不易放出(chu)，在塵(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)壓(ya)梯度會產(chan)生局(ju)部擊穿和(he)放電(dian)(dian)(dian)現象。這些情況都會造成除塵(chen)(chen)效(xiao)率下降。

電(dian)(dian)(dian)(dian)除塵(chen)器的(de)基本原理(li)是利用(yong)電(dian)(dian)(dian)(dian)力(li)捕集煙氣(qi)中的(de)粉塵(chen)，主要包(bao)括以下四個相互有關的(de)物理(li)過程(cheng): (1) 氣(qi)體的(de)電(dian)(dian)(dian)(dian)離。(2) 粉塵(chen)的(de)荷電(dian)(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)(dian)粉塵(chen)向電(dian)(dian)(dian)(dian)極移(yi)動(dong)。(4) 荷電(dian)(dian)(dian)(dian)粉塵(chen)的(de)捕集。
