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)(chen)(chen)(chen)器是(shi)以靜電(dian)(dian)(dian)(dian)凈化(hua)法來收(shou)捕廢氣(qi)(qi)中的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)凈化(hua)工(gong)作上要是(shi)依(yi)靠電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)(he)沉(chen)淀(dian)兩個系統來完成的(de)(de)(de)(de)，當(dang)含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)體進(jin)(jin)人氣(qi)(qi)刺叭(ba)時，含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流分(fen)布板以及折流板的(de)(de)(de)(de)調整后，使氣(qi)(qi)流能較(jiao)均勻地進(jin)(jin)人電(dian)(dian)(dian)(dian)場。在(zai)(zai)橫斷面擴大(da)的(de)(de)(de)(de)作用下(xia)，氣(qi)(qi)流速度迅速降低，其中有些(xie)較(jiao)重的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒便失去速度而沉(chen)降下(xia)來。進(jin)(jin)人電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含(han)塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)體由(you)于電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)人高壓直流電(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附(fu)近產生電(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)體電(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)離后的(de)(de)(de)(de)氣(qi)(qi)體中存(cun)在(zai)(zai)大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離子(zi)(zi)，這些(xie)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離子(zi)(zi)與進(jin)(jin)人電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)結合起來，使塵(chen)(chen)(chen)(chen)(chen)粒帶(dai)電(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作用下(xia)趨向本設備陽(yang)極(ji)(ji)(正極(ji)(ji)、本設備采(cai)用負高壓制)和(he)(he)陰(yin)極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)子(zi)(zi)分(fen)別(bie)沉(chen)積(ji)(ji)在(zai)(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)上，通(tong)過設備陰(yin)陽(yang)極(ji)(ji)振(zhen)(zhen)打系統的(de)(de)(de)(de)振(zhen)(zhen)打，使沉(chen)積(ji)(ji)在(zai)(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)振(zhen)(zhen)落，進(jin)(jin)人集灰(hui)斗 通(tong)過排(pai)灰(hui)裝置放出，回收(shou)有物料，被)凈化(hua)的(de)(de)(de)(de)氣(qi)(qi)體排(pai)入大(da)氣(qi)(qi)。

工作原理

靜電(dian)(dian)除塵(chen)器的(de)工作原理是利用高(gao)(gao)壓(ya)(ya)電(dian)(dian)場(chang)使(shi)(shi)煙氣(qi)(qi)發生(sheng)電(dian)(dian)離，氣(qi)(qi)流(liu)(liu)(liu)中的(de)粉(fen)塵(chen)荷電(dian)(dian)在電(dian)(dian)場(chang)作用下與(yu)氣(qi)(qi)流(liu)(liu)(liu)分離。負(fu)極由(you)不(bu)同(tong)斷(duan)面形狀的(de)金(jin)屬導線制(zhi)成，叫(jiao)放電(dian)(dian)電(dian)(dian)極。正極由(you)不(bu)同(tong)幾何形狀的(de)金(jin)屬板制(zhi)成，叫(jiao)集(ji)塵(chen)電(dian)(dian)極。靜電(dian)(dian)除塵(chen)器的(de)性能(neng)受粉(fen)塵(chen)性質、設備(bei)構造和(he)煙氣(qi)(qi)流(liu)(liu)(liu)速等三個因素的(de)影(ying)響。粉(fen)塵(chen)的(de)比電(dian)(dian)阻(zu)是評價導電(dian)(dian)性的(de)指標，它(ta)對除塵(chen)效率有直接(jie)的(de)影(ying)響。比電(dian)(dian)阻(zu)過低(di)，塵(chen)粒(li)難以保(bao)持(chi)在集(ji)塵(chen)電(dian)(dian)極上，致使(shi)(shi)其重返氣(qi)(qi)流(liu)(liu)(liu)。比電(dian)(dian)阻(zu)過高(gao)(gao)，到達集(ji)塵(chen)電(dian)(dian)極的(de)塵(chen)粒(li)電(dian)(dian)荷不(bu)易放出，在塵(chen)層之間形成電(dian)(dian)壓(ya)(ya)梯度會產生(sheng)局部擊(ji)穿和(he)放電(dian)(dian)現象(xiang)。這些情況都會造成除塵(chen)效率下降(jiang)。

電除塵(chen)(chen)(chen)器的(de)基本原理是利用電力(li)捕(bu)集(ji)煙氣(qi)中的(de)粉(fen)(fen)塵(chen)(chen)(chen)，主要包括以下四個(ge)相互有(you)關的(de)物理過程(cheng): (1) 氣(qi)體的(de)電離。(2) 粉(fen)(fen)塵(chen)(chen)(chen)的(de)荷電。(3) 荷電粉(fen)(fen)塵(chen)(chen)(chen)向電極移動。(4) 荷電粉(fen)(fen)塵(chen)(chen)(chen)的(de)捕(bu)集(ji)。
