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)除塵(chen)(chen)(chen)(chen)(chen)器是以(yi)靜電(dian)(dian)凈(jing)化法來收捕(bu)廢(fei)氣(qi)(qi)中(zhong)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)，它的(de)(de)(de)(de)凈(jing)化工作上要是依靠電(dian)(dian)暈(yun)(yun)極(ji)和沉(chen)(chen)淀(dian)兩個系(xi)統(tong)來完成的(de)(de)(de)(de)，當含塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進人(ren)氣(qi)(qi)刺叭(ba)時(shi)，含塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受到(dao)氣(qi)(qi)流(liu)分布板以(yi)及折(zhe)流(liu)板的(de)(de)(de)(de)調(diao)整后(hou)，使氣(qi)(qi)流(liu)能較均勻地進人(ren)電(dian)(dian)場(chang)。在(zai)橫斷面擴大的(de)(de)(de)(de)作用下(xia)，氣(qi)(qi)流(liu)速(su)度(du)迅速(su)降低(di)，其中(zhong)有(you)些較重(zhong)的(de)(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒便失去速(su)度(du)而沉(chen)(chen)降下(xia)來。進人(ren)電(dian)(dian)場(chang)的(de)(de)(de)(de)含塵(chen)(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)暈(yun)(yun)極(ji)通(tong)人(ren)高壓(ya)直流(liu)電(dian)(dian)，則在(zai)電(dian)(dian)暈(yun)(yun)極(ji)附近產生電(dian)(dian)暈(yun)(yun)現象(xiang)，使氣(qi)(qi)體(ti)(ti)電(dian)(dian)離，電(dian)(dian)離后(hou)的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)中(zhong)存(cun)在(zai)大量(liang)的(de)(de)(de)(de)電(dian)(dian)子(zi)和離子(zi)，這些電(dian)(dian)子(zi)和離子(zi)與進人(ren)電(dian)(dian)場(chang)的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)結合(he)起來，使塵(chen)(chen)(chen)(chen)(chen)粒帶電(dian)(dian)，帶電(dian)(dian)塵(chen)(chen)(chen)(chen)(chen)粒在(zai)電(dian)(dian)場(chang)力的(de)(de)(de)(de)作用下(xia)趨向本(ben)設(she)(she)備陽(yang)極(ji)(正極(ji)、本(ben)設(she)(she)備采(cai)用負高壓(ya)制)和陰(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)子(zi)分別(bie)沉(chen)(chen)積(ji)在(zai)相(xiang)應的(de)(de)(de)(de)電(dian)(dian)極(ji)上，通(tong)過(guo)設(she)(she)備陰(yin)陽(yang)極(ji)振(zhen)(zhen)打(da)(da)系(xi)統(tong)的(de)(de)(de)(de)振(zhen)(zhen)打(da)(da)，使沉(chen)(chen)積(ji)在(zai)陰(yin)陽(yang)電(dian)(dian)極(ji)上的(de)(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)振(zhen)(zhen)落，進人(ren)集灰斗(dou) 通(tong)過(guo)排灰裝置放出，回收有(you)物料，被)凈(jing)化的(de)(de)(de)(de)氣(qi)(qi)體(ti)(ti)排入(ru)大氣(qi)(qi)。

工作原理

靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)工(gong)作原理是利用(yong)高壓(ya)電(dian)(dian)(dian)(dian)場(chang)使煙氣發生(sheng)電(dian)(dian)(dian)(dian)離，氣流(liu)中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)(chen)荷(he)(he)電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場(chang)作用(yong)下與氣流(liu)分離。負極由不同斷面(mian)形狀的(de)金屬導(dao)線制成(cheng)(cheng)，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極。正極由不同幾何形狀的(de)金屬板制成(cheng)(cheng)，叫集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極。靜(jing)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)性(xing)能受(shou)粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設備構造和煙氣流(liu)速(su)等(deng)三個因素的(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)阻(zu)是評價導(dao)電(dian)(dian)(dian)(dian)性(xing)的(de)指(zhi)標，它對除(chu)塵(chen)(chen)(chen)(chen)效率有直接的(de)影(ying)響。比電(dian)(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)粒難(nan)以保持在集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上(shang)，致使其重返氣流(liu)。比電(dian)(dian)(dian)(dian)阻(zu)過高，到達(da)集(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷(he)(he)不易放出，在塵(chen)(chen)(chen)(chen)層(ceng)之間形成(cheng)(cheng)電(dian)(dian)(dian)(dian)壓(ya)梯度會產生(sheng)局部擊穿和放電(dian)(dian)(dian)(dian)現象。這些(xie)情況都(dou)會造成(cheng)(cheng)除(chu)塵(chen)(chen)(chen)(chen)效率下降。

電除塵器的(de)基(ji)本原理(li)是利用電力捕(bu)集(ji)(ji)煙氣(qi)中的(de)粉塵，主要(yao)包括(kuo)以下(xia)四(si)個相互(hu)有關的(de)物理(li)過程: (1) 氣(qi)體的(de)電離。(2) 粉塵的(de)荷電。(3) 荷電粉塵向(xiang)電極(ji)移動(dong)。(4) 荷電粉塵的(de)捕(bu)集(ji)(ji)。
