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(jing)電(dian)(dian)(dian)(dian)除塵(chen)(chen)器是(shi)以(yi)靜(jing)電(dian)(dian)(dian)(dian)凈化(hua)法來(lai)收(shou)(shou)捕廢氣(qi)(qi)(qi)中(zhong)的粉塵(chen)(chen)，它的凈化(hua)工作上(shang)要是(shi)依靠電(dian)(dian)(dian)(dian)暈極(ji)和(he)沉淀(dian)兩(liang)個系統(tong)來(lai)完成的，當(dang)含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)進人(ren)氣(qi)(qi)(qi)刺叭時(shi)，含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)(liu)分布板(ban)以(yi)及折流(liu)(liu)板(ban)的調整后，使(shi)(shi)(shi)氣(qi)(qi)(qi)流(liu)(liu)能較均勻地(di)進人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)。在橫斷面擴(kuo)大的作用下(xia)，氣(qi)(qi)(qi)流(liu)(liu)速度迅(xun)速降(jiang)低，其中(zhong)有些(xie)(xie)較重(zhong)的塵(chen)(chen)粒便失去速度而沉降(jiang)下(xia)來(lai)。進人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的含塵(chen)(chen)氣(qi)(qi)(qi)體(ti)由于電(dian)(dian)(dian)(dian)暈極(ji)通(tong)人(ren)高(gao)壓直流(liu)(liu)電(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)暈極(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)暈現象(xiang)，使(shi)(shi)(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)離(li)后的氣(qi)(qi)(qi)體(ti)中(zhong)存在大量的電(dian)(dian)(dian)(dian)子和(he)離(li)子，這些(xie)(xie)電(dian)(dian)(dian)(dian)子和(he)離(li)子與(yu)進人(ren)電(dian)(dian)(dian)(dian)場(chang)(chang)的粉塵(chen)(chen)結合起來(lai)，使(shi)(shi)(shi)塵(chen)(chen)粒帶電(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)塵(chen)(chen)粒在電(dian)(dian)(dian)(dian)場(chang)(chang)力(li)的作用下(xia)趨向本設備(bei)陽(yang)(yang)極(ji)(正極(ji)、本設備(bei)采用負高(gao)壓制)和(he)陰(yin)極(ji)(負極(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)子分別(bie)沉積在相(xiang)應(ying)的電(dian)(dian)(dian)(dian)極(ji)上(shang)，通(tong)過(guo)設備(bei)陰(yin)陽(yang)(yang)極(ji)振打系統(tong)的振打，使(shi)(shi)(shi)沉積在陰(yin)陽(yang)(yang)電(dian)(dian)(dian)(dian)極(ji)上(shang)的粉塵(chen)(chen)振落，進人(ren)集灰斗 通(tong)過(guo)排(pai)灰裝置放出，回收(shou)(shou)有物(wu)料(liao)，被(bei))凈化(hua)的氣(qi)(qi)(qi)體(ti)排(pai)入大氣(qi)(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)工作原理是利用高(gao)壓電(dian)(dian)(dian)場使煙氣(qi)發生電(dian)(dian)(dian)離(li)，氣(qi)流(liu)中(zhong)的(de)粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用下與氣(qi)流(liu)分離(li)。負極由不同(tong)斷面(mian)形狀的(de)金屬(shu)導線制成(cheng)(cheng)，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。正極由不同(tong)幾何形狀的(de)金屬(shu)板制成(cheng)(cheng)，叫集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極。靜電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器的(de)性能受粉塵(chen)(chen)(chen)(chen)性質、設備構(gou)造(zao)和煙氣(qi)流(liu)速等三個因素的(de)影(ying)響(xiang)。粉塵(chen)(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)阻(zu)(zu)是評價導電(dian)(dian)(dian)性的(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)(chen)效率(lv)有直接的(de)影(ying)響(xiang)。比(bi)電(dian)(dian)(dian)阻(zu)(zu)過(guo)低，塵(chen)(chen)(chen)(chen)粒難以保(bao)持在集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極上，致使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)阻(zu)(zu)過(guo)高(gao)，到(dao)達集(ji)(ji)塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易(yi)放(fang)出，在塵(chen)(chen)(chen)(chen)層之間形成(cheng)(cheng)電(dian)(dian)(dian)壓梯度會產生局部擊(ji)穿和放(fang)電(dian)(dian)(dian)現象。這些情況都會造(zao)成(cheng)(cheng)除(chu)塵(chen)(chen)(chen)(chen)效率(lv)下降。

電(dian)(dian)除塵器的(de)基本原理是利(li)用電(dian)(dian)力捕集(ji)煙氣中(zhong)的(de)粉(fen)(fen)塵，主要包括(kuo)以下四個相互(hu)有關的(de)物理過(guo)程: (1) 氣體(ti)的(de)電(dian)(dian)離。(2) 粉(fen)(fen)塵的(de)荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)(fen)塵向電(dian)(dian)極移動(dong)。(4) 荷(he)電(dian)(dian)粉(fen)(fen)塵的(de)捕集(ji)。
