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(wo)式靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)是(shi)(shi)以靜電(dian)(dian)(dian)(dian)(dian)凈化法來(lai)收捕(bu)廢氣(qi)中的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈化工作(zuo)上(shang)要是(shi)(shi)依靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)和沉淀兩個(ge)系統來(lai)完成(cheng)的(de)(de)，當含塵(chen)(chen)氣(qi)體(ti)進(jin)(jin)人(ren)(ren)氣(qi)刺叭時，含塵(chen)(chen)氣(qi)體(ti)受(shou)到(dao)氣(qi)流分布板(ban)以及折流板(ban)的(de)(de)調整(zheng)后(hou)，使氣(qi)流能較均勻地進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)。在(zai)橫斷面擴大(da)的(de)(de)作(zuo)用下，氣(qi)流速(su)(su)度迅速(su)(su)降(jiang)低，其中有些較重(zhong)的(de)(de)塵(chen)(chen)粒便失(shi)去速(su)(su)度而沉降(jiang)下來(lai)。進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)的(de)(de)含塵(chen)(chen)氣(qi)體(ti)由(you)于(yu)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通人(ren)(ren)高壓直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附(fu)近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)氣(qi)體(ti)中存在(zai)大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和離子(zi)(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和離子(zi)(zi)(zi)與(yu)進(jin)(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)的(de)(de)粉塵(chen)(chen)結合(he)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)(chang)力的(de)(de)作(zuo)用下趨向本設(she)(she)備(bei)(bei)陽極(ji)(正極(ji)、本設(she)(she)備(bei)(bei)采用負高壓制(zhi))和陰極(ji)(負極(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)分別沉積在(zai)相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)，通過設(she)(she)備(bei)(bei)陰陽極(ji)振打系統的(de)(de)振打，使沉積在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(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(hui)收有物料(liao)，被)凈化的(de)(de)氣(qi)體(ti)排入大(da)氣(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)工作原理是利用(yong)高壓電(dian)(dian)(dian)(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)(dian)(dian)(dian)離，氣流中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)場作用(yong)下與氣流分(fen)離。負極(ji)(ji)由不(bu)同斷(duan)面形狀的(de)(de)(de)金屬導線制成，叫(jiao)放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不(bu)同幾(ji)何形狀的(de)(de)(de)金屬板(ban)制成，叫(jiao)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設(she)備構造和(he)煙氣流速等三個因素的(de)(de)(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)是評價(jia)導電(dian)(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指標(biao)，它(ta)對除(chu)塵(chen)(chen)(chen)(chen)效率有直(zhi)接的(de)(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過低(di)，塵(chen)(chen)(chen)(chen)粒難(nan)以保持在集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣流。比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)過高，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)(chen)(chen)層之間形成電(dian)(dian)(dian)(dian)(dian)(dian)壓梯度(du)會(hui)(hui)產(chan)生局(ju)部擊穿(chuan)和(he)放電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況都會(hui)(hui)造成除(chu)塵(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)(dian)(dian)除塵(chen)器的(de)基本原理(li)是利用電(dian)(dian)(dian)(dian)力捕(bu)集煙氣中的(de)粉(fen)(fen)塵(chen)，主要包括以下四(si)個相(xiang)互有關的(de)物理(li)過程: (1) 氣體(ti)(ti)的(de)電(dian)(dian)(dian)(dian)離(li)。(2) 粉(fen)(fen)塵(chen)的(de)荷電(dian)(dian)(dian)(dian)。(3) 荷電(dian)(dian)(dian)(dian)粉(fen)(fen)塵(chen)向電(dian)(dian)(dian)(dian)極移動。(4) 荷電(dian)(dian)(dian)(dian)粉(fen)(fen)塵(chen)的(de)捕(bu)集。
