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)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法來收(shou)捕廢(fei)氣(qi)(qi)(qi)(qi)中(zhong)的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈(jing)(jing)化(hua)工作(zuo)上(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極和(he)沉淀(dian)兩個(ge)系統(tong)來完(wan)成的(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)進人(ren)氣(qi)(qi)(qi)(qi)刺叭(ba)時，含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)(qi)流(liu)(liu)分布板以及折流(liu)(liu)板的(de)(de)調整后，使(shi)氣(qi)(qi)(qi)(qi)流(liu)(liu)能(neng)較(jiao)均勻地進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面擴(kuo)大(da)的(de)(de)作(zuo)用(yong)下(xia)(xia)，氣(qi)(qi)(qi)(qi)流(liu)(liu)速度迅速降(jiang)低，其中(zhong)有些(xie)較(jiao)重的(de)(de)塵(chen)(chen)粒便失(shi)去速度而沉降(jiang)下(xia)(xia)來。進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極通人(ren)高(gao)(gao)壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)后的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)存在(zai)大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子，這些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和(he)離(li)子與(yu)進人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)結合起來，使(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)作(zuo)用(yong)下(xia)(xia)趨(qu)向本設(she)備陽(yang)極(正(zheng)極、本設(she)備采用(yong)負(fu)高(gao)(gao)壓制(zhi))和(he)陰(yin)極(負(fu)極) ， 釋(shi)放出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子分別沉積在(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極上(shang)，通過設(she)備陰(yin)陽(yang)極振(zhen)打系統(tong)的(de)(de)振(zhen)打，使(shi)沉積在(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極上(shang)的(de)(de)粉塵(chen)(chen)振(zhen)落，進人(ren)集灰斗 通過排灰裝(zhuang)置放出(chu)，回收(shou)有物(wu)料，被)凈(jing)(jing)化(hua)的(de)(de)氣(qi)(qi)(qi)(qi)體(ti)(ti)排入大(da)氣(qi)(qi)(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)(de)(de)(de)工作(zuo)原理是利用高(gao)壓(ya)電(dian)(dian)(dian)場(chang)使(shi)煙氣(qi)(qi)發生電(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)(de)(de)(de)(de)粉塵(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作(zuo)用下(xia)與氣(qi)(qi)流(liu)分離。負極(ji)由不(bu)同(tong)斷面形狀的(de)(de)(de)(de)(de)金屬(shu)導線制成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不(bu)同(tong)幾何形狀的(de)(de)(de)(de)(de)金屬(shu)板制成，叫集(ji)塵(chen)電(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)(de)(de)(de)性能(neng)受粉塵(chen)性質、設備構造和(he)煙氣(qi)(qi)流(liu)速等三個因(yin)素的(de)(de)(de)(de)(de)影響。粉塵(chen)的(de)(de)(de)(de)(de)比電(dian)(dian)(dian)阻(zu)是評(ping)價導電(dian)(dian)(dian)性的(de)(de)(de)(de)(de)指(zhi)標，它對除(chu)塵(chen)效率(lv)有直接的(de)(de)(de)(de)(de)影響。比電(dian)(dian)(dian)阻(zu)過低，塵(chen)粒(li)難以保持(chi)在集(ji)塵(chen)電(dian)(dian)(dian)極(ji)上，致使(shi)其重返氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)阻(zu)過高(gao)，到達集(ji)塵(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)(de)塵(chen)粒(li)電(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)層之間形成電(dian)(dian)(dian)壓(ya)梯度(du)會產生局部擊穿和(he)放電(dian)(dian)(dian)現(xian)象。這(zhe)些情況都(dou)會造成除(chu)塵(chen)效率(lv)下(xia)降。

電除塵(chen)器的(de)基本原理(li)是利用電力捕集煙氣(qi)中(zhong)的(de)粉塵(chen)，主要包括以下四個相(xiang)互有關的(de)物理(li)過程: (1) 氣(qi)體的(de)電離。(2) 粉塵(chen)的(de)荷電。(3) 荷電粉塵(chen)向電極(ji)移動(dong)。(4) 荷電粉塵(chen)的(de)捕集。
