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)除塵(chen)(chen)(chen)器是以(yi)(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈化法來收捕廢氣(qi)(qi)中的粉塵(chen)(chen)(chen)，它(ta)的凈化工作(zuo)上要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和(he)(he)沉(chen)淀兩個系統(tong)(tong)來完成的，當含(han)(han)塵(chen)(chen)(chen)氣(qi)(qi)體進(jin)(jin)人(ren)氣(qi)(qi)刺叭時，含(han)(han)塵(chen)(chen)(chen)氣(qi)(qi)體受到氣(qi)(qi)流(liu)分(fen)布板以(yi)(yi)及折流(liu)板的調(diao)整(zheng)后，使(shi)氣(qi)(qi)流(liu)能較均勻地(di)進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)。在橫斷面擴大(da)(da)的作(zuo)用下，氣(qi)(qi)流(liu)速度(du)迅(xun)速降低，其(qi)中有些(xie)較重的塵(chen)(chen)(chen)粒(li)便失去速度(du)而(er)沉(chen)降下來。進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的含(han)(han)塵(chen)(chen)(chen)氣(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)人(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近(jin)產(chan)生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離后的氣(qi)(qi)體中存在大(da)(da)量的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離子(zi)(zi)，這(zhe)些(xie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)和(he)(he)離子(zi)(zi)與進(jin)(jin)人(ren)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的粉塵(chen)(chen)(chen)結(jie)合起來，使(shi)塵(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的作(zuo)用下趨向(xiang)本(ben)設備陽(yang)極(ji)(ji)(正極(ji)(ji)、本(ben)設備采(cai)用負高壓(ya)制)和(he)(he)陰極(ji)(ji)(負極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)分(fen)別沉(chen)積(ji)在相應的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，通(tong)過設備陰陽(yang)極(ji)(ji)振(zhen)打系統(tong)(tong)的振(zhen)打，使(shi)沉(chen)積(ji)在陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的粉塵(chen)(chen)(chen)振(zhen)落，進(jin)(jin)人(ren)集灰斗(dou) 通(tong)過排(pai)灰裝置放出，回收有物料，被)凈化的氣(qi)(qi)體排(pai)入大(da)(da)氣(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器的工作原理是利用(yong)高壓電(dian)(dian)(dian)場使煙氣(qi)(qi)發生電(dian)(dian)(dian)離(li)，氣(qi)(qi)流(liu)中的粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用(yong)下與氣(qi)(qi)流(liu)分離(li)。負極(ji)由不同斷(duan)面形狀的金屬(shu)導線制(zhi)成，叫(jiao)放(fang)(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由不同幾(ji)何(he)形狀的金屬(shu)板(ban)制(zhi)成，叫(jiao)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器的性能受粉塵(chen)(chen)(chen)(chen)性質、設備構造和煙氣(qi)(qi)流(liu)速(su)等(deng)三個(ge)因素(su)的影(ying)響。粉塵(chen)(chen)(chen)(chen)的比電(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)性的指(zhi)標，它(ta)對(dui)除(chu)(chu)塵(chen)(chen)(chen)(chen)效(xiao)率有(you)直接的影(ying)響。比電(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)(chen)粒(li)難以保持在集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上(shang)，致使其重返氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)阻過(guo)高，到達(da)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)荷不易放(fang)(fang)(fang)出，在塵(chen)(chen)(chen)(chen)層之間形成電(dian)(dian)(dian)壓梯度會產生局部擊穿和放(fang)(fang)(fang)電(dian)(dian)(dian)現象。這些情況都(dou)會造成除(chu)(chu)塵(chen)(chen)(chen)(chen)效(xiao)率下降。

電除塵器(qi)的(de)(de)基(ji)本原理(li)是(shi)利用電力(li)捕集煙(yan)氣中的(de)(de)粉(fen)塵，主要包括以下四個(ge)相互(hu)有(you)關的(de)(de)物理(li)過程: (1) 氣體的(de)(de)電離。(2) 粉(fen)塵的(de)(de)荷(he)電。(3) 荷(he)電粉(fen)塵向電極移動。(4) 荷(he)電粉(fen)塵的(de)(de)捕集。
