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)除塵(chen)(chen)器是以靜電(dian)(dian)(dian)(dian)凈化(hua)法來(lai)(lai)收(shou)捕廢氣(qi)中的(de)(de)(de)粉塵(chen)(chen)，它的(de)(de)(de)凈化(hua)工(gong)作(zuo)上(shang)要是依靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)和(he)沉(chen)淀兩(liang)個(ge)系統來(lai)(lai)完成(cheng)的(de)(de)(de)，當含塵(chen)(chen)氣(qi)體進(jin)人氣(qi)刺叭時(shi)，含塵(chen)(chen)氣(qi)體受到氣(qi)流分布板(ban)以及折流板(ban)的(de)(de)(de)調(diao)整(zheng)后，使(shi)(shi)氣(qi)流能較均(jun)勻(yun)地進(jin)人電(dian)(dian)(dian)(dian)場(chang)。在(zai)橫斷面擴(kuo)大的(de)(de)(de)作(zuo)用下，氣(qi)流速度迅速降低，其(qi)中有些較重的(de)(de)(de)塵(chen)(chen)粒便失去速度而沉(chen)降下來(lai)(lai)。進(jin)人電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)含塵(chen)(chen)氣(qi)體由于(yu)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)通人高(gao)壓(ya)直流電(dian)(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)(shi)氣(qi)體電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)氣(qi)體中存在(zai)大量(liang)的(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這(zhe)些電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進(jin)人電(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵(chen)(chen)結合(he)起來(lai)(lai)，使(shi)(shi)塵(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)作(zuo)用下趨向(xiang)本設備(bei)陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本設備(bei)采用負(fu)高(gao)壓(ya)制)和(he)陰(yin)極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放(fang)(fang)出電(dian)(dian)(dian)(dian)子(zi)分別沉(chen)積(ji)在(zai)相應的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，通過設備(bei)陰(yin)陽極(ji)(ji)(ji)振打系統的(de)(de)(de)振打，使(shi)(shi)沉(chen)積(ji)在(zai)陰(yin)陽電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)粉塵(chen)(chen)振落(luo)，進(jin)人集灰斗 通過排灰裝置放(fang)(fang)出，回收(shou)有物料(liao)，被)凈化(hua)的(de)(de)(de)氣(qi)體排入大氣(qi)。

工作原(yuan)理

靜電(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)工作原理是利用高(gao)壓(ya)電(dian)場(chang)使煙氣(qi)發生電(dian)離，氣(qi)流中的(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)在(zai)電(dian)場(chang)作用下(xia)與氣(qi)流分離。負(fu)極(ji)(ji)由不同斷面形狀(zhuang)的(de)(de)金(jin)(jin)屬導(dao)線制(zhi)成(cheng)(cheng)，叫(jiao)放(fang)電(dian)電(dian)極(ji)(ji)。正極(ji)(ji)由不同幾何形狀(zhuang)的(de)(de)金(jin)(jin)屬板制(zhi)成(cheng)(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)電(dian)極(ji)(ji)。靜電(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)性(xing)(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)(xing)質、設備構造和煙氣(qi)流速等三個因素的(de)(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)的(de)(de)比電(dian)阻是評價導(dao)電(dian)性(xing)(xing)的(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)效率有直接的(de)(de)影響(xiang)。比電(dian)阻過低，塵(chen)(chen)(chen)粒(li)難以(yi)保持在(zai)集(ji)塵(chen)(chen)(chen)電(dian)極(ji)(ji)上，致使其(qi)重返氣(qi)流。比電(dian)阻過高(gao)，到達(da)集(ji)塵(chen)(chen)(chen)電(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)荷不易放(fang)出(chu)，在(zai)塵(chen)(chen)(chen)層之間形成(cheng)(cheng)電(dian)壓(ya)梯(ti)度(du)會產生局(ju)部擊穿和放(fang)電(dian)現象。這些情況(kuang)都(dou)會造成(cheng)(cheng)除(chu)塵(chen)(chen)(chen)效率下(xia)降。

電(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)基本原理是利用電(dian)(dian)(dian)(dian)力捕集煙氣中的(de)(de)粉塵(chen)(chen)，主要(yao)包括以下(xia)四個(ge)相(xiang)互有關的(de)(de)物理過程(cheng): (1) 氣體(ti)的(de)(de)電(dian)(dian)(dian)(dian)離。(2) 粉塵(chen)(chen)的(de)(de)荷(he)電(dian)(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)(dian)(dian)極移(yi)動(dong)。(4) 荷(he)電(dian)(dian)(dian)(dian)粉塵(chen)(chen)的(de)(de)捕集。
