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)器(qi)是以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈(jing)(jing)化(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)粉塵(chen)(chen)，它(ta)的(de)(de)(de)(de)凈(jing)(jing)化(hua)工作上(shang)要是依靠(kao)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)和沉淀兩個系(xi)統來(lai)完成的(de)(de)(de)(de)，當含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)進人(ren)(ren)氣(qi)(qi)(qi)刺叭(ba)時，含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)受到氣(qi)(qi)(qi)流分(fen)布板(ban)以(yi)及折流板(ban)的(de)(de)(de)(de)調整后(hou)，使氣(qi)(qi)(qi)流能(neng)較均勻地進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)橫(heng)斷(duan)面擴大(da)的(de)(de)(de)(de)作用下，氣(qi)(qi)(qi)流速度(du)迅(xun)速降低，其(qi)中(zhong)有(you)些較重的(de)(de)(de)(de)塵(chen)(chen)粒便失去速度(du)而沉降下來(lai)。進人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通人(ren)(ren)高壓(ya)直流電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附近產(chan)生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使氣(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離，電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)中(zhong)存在(zai)(zai)大(da)量的(de)(de)(de)(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)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)(de)(de)粉塵(chen)(chen)結合起來(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)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)(de)作用下趨向本設(she)備陽(yang)極(ji)(ji)(正極(ji)(ji)、本設(she)備采(cai)用負(fu)高壓(ya)制(zhi))和陰(yin)極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別沉積在(zai)(zai)相應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，通過設(she)備陰(yin)陽(yang)極(ji)(ji)振(zhen)打(da)系(xi)統的(de)(de)(de)(de)振(zhen)打(da)，使沉積在(zai)(zai)陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)(de)(de)粉塵(chen)(chen)振(zhen)落(luo)，進人(ren)(ren)集灰(hui)斗(dou) 通過排(pai)灰(hui)裝置(zhi)放出，回收有(you)物料，被(bei))凈(jing)(jing)化(hua)的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)(ti)排(pai)入大(da)氣(qi)(qi)(qi)。

工作原(yuan)理(li)

靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)(de)(de)工(gong)作原理是(shi)利用高壓電(dian)(dian)(dian)場(chang)使煙氣(qi)發生(sheng)電(dian)(dian)(dian)離，氣(qi)流(liu)(liu)中的(de)(de)(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)作用下與氣(qi)流(liu)(liu)分離。負極(ji)由(you)不同(tong)斷(duan)面(mian)形狀(zhuang)的(de)(de)(de)金屬導(dao)線制(zhi)成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極(ji)。正極(ji)由(you)不同(tong)幾何(he)形狀(zhuang)的(de)(de)(de)金屬板制(zhi)成(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)。靜(jing)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器的(de)(de)(de)性能(neng)受粉塵(chen)(chen)(chen)性質、設備構造和煙氣(qi)流(liu)(liu)速(su)等(deng)三個因素的(de)(de)(de)影(ying)響。粉塵(chen)(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)阻(zu)是(shi)評價導(dao)電(dian)(dian)(dian)性的(de)(de)(de)指標，它(ta)對除(chu)(chu)塵(chen)(chen)(chen)效率(lv)有直(zhi)接(jie)的(de)(de)(de)影(ying)響。比(bi)電(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)粒難以(yi)保持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其重(zhong)返氣(qi)流(liu)(liu)。比(bi)電(dian)(dian)(dian)阻(zu)過(guo)高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易(yi)放(fang)出，在塵(chen)(chen)(chen)層之間(jian)形成(cheng)電(dian)(dian)(dian)壓梯度會產生(sheng)局部擊穿和放(fang)電(dian)(dian)(dian)現象。這些(xie)情況都(dou)會造成(cheng)除(chu)(chu)塵(chen)(chen)(chen)效率(lv)下降。

電(dian)(dian)(dian)除塵(chen)器的(de)基本原理是利用電(dian)(dian)(dian)力捕集煙氣中的(de)粉塵(chen)，主(zhu)要(yao)包括以(yi)下(xia)四個相互有關的(de)物理過程: (1) 氣體的(de)電(dian)(dian)(dian)離。(2) 粉塵(chen)的(de)荷(he)電(dian)(dian)(dian)。(3) 荷(he)電(dian)(dian)(dian)粉塵(chen)向電(dian)(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)(dian)粉塵(chen)的(de)捕集。
