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)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)(dian)凈化(hua)法來(lai)(lai)收捕廢(fei)氣(qi)(qi)(qi)(qi)(qi)中(zhong)(zhong)的(de)粉塵(chen)(chen)(chen)，它的(de)凈化(hua)工(gong)作(zuo)上(shang)(shang)要(yao)是(shi)依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉淀兩個(ge)系統(tong)來(lai)(lai)完(wan)成的(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)進人(ren)(ren)(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭(ba)時(shi)，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)(qi)(qi)流分布板以及折流板的(de)調整(zheng)后，使(shi)氣(qi)(qi)(qi)(qi)(qi)流能(neng)較(jiao)均勻地進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面擴大的(de)作(zuo)用下，氣(qi)(qi)(qi)(qi)(qi)流速度迅速降低，其中(zhong)(zhong)有些較(jiao)重的(de)塵(chen)(chen)(chen)粒便失去速度而(er)沉降下來(lai)(lai)。進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通(tong)人(ren)(ren)(ren)高(gao)壓直流電(dian)(dian)(dian)(dian)(dian)，則(ze)在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附(fu)近產生(sheng)電(dian)(dian)(dian)(dian)(dian)暈(yun)現(xian)象，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后的(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)(zhong)存在(zai)大量(liang)的(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi)與進人(ren)(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)粉塵(chen)(chen)(chen)結合(he)起來(lai)(lai)，使(shi)塵(chen)(chen)(chen)粒帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)作(zuo)用下趨向本設備陽極(ji)(正極(ji)、本設備采(cai)用負高(gao)壓制(zhi))和陰極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)分別(bie)沉積(ji)在(zai)相(xiang)應的(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)，通(tong)過設備陰陽極(ji)振打系統(tong)的(de)振打，使(shi)沉積(ji)在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)的(de)粉塵(chen)(chen)(chen)振落，進人(ren)(ren)(ren)集灰(hui)斗 通(tong)過排灰(hui)裝置放出，回收有物料，被(bei))凈化(hua)的(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)(dian)除塵(chen)器的(de)工作(zuo)原理是利用高(gao)壓電(dian)(dian)(dian)(dian)場(chang)(chang)使煙氣發生(sheng)電(dian)(dian)(dian)(dian)離，氣流中(zhong)的(de)粉塵(chen)荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場(chang)(chang)作(zuo)用下與(yu)氣流分離。負極由不同斷面形(xing)(xing)狀的(de)金屬導線制成，叫(jiao)放(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由不同幾何形(xing)(xing)狀的(de)金屬板制成，叫(jiao)集塵(chen)電(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)除塵(chen)器的(de)性(xing)(xing)能受粉塵(chen)性(xing)(xing)質、設備構造和(he)煙氣流速(su)等三個因(yin)素的(de)影(ying)響。粉塵(chen)的(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)是評價導電(dian)(dian)(dian)(dian)性(xing)(xing)的(de)指(zhi)標，它對(dui)除塵(chen)效率有直接的(de)影(ying)響。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)粒(li)難以保(bao)持在集塵(chen)電(dian)(dian)(dian)(dian)極上，致使其重(zhong)返氣流。比(bi)電(dian)(dian)(dian)(dian)阻(zu)過高(gao)，到達集塵(chen)電(dian)(dian)(dian)(dian)極的(de)塵(chen)粒(li)電(dian)(dian)(dian)(dian)荷不易放(fang)(fang)出，在塵(chen)層之間形(xing)(xing)成電(dian)(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿和(he)放(fang)(fang)電(dian)(dian)(dian)(dian)現象。這(zhe)些(xie)情況都會造成除塵(chen)效率下降。

電(dian)除塵器的(de)(de)基(ji)本原理(li)是(shi)利(li)用電(dian)力(li)捕集煙氣中的(de)(de)粉塵，主(zhu)要(yao)包括以下(xia)四個相互(hu)有關的(de)(de)物理(li)過程: (1) 氣體(ti)的(de)(de)電(dian)離。(2) 粉塵的(de)(de)荷電(dian)。(3) 荷電(dian)粉塵向電(dian)極(ji)移(yi)動。(4) 荷電(dian)粉塵的(de)(de)捕集。
