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(wo)式靜電(dian)(dian)(dian)(dian)(dian)除塵器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)凈化法來收捕廢(fei)氣(qi)(qi)(qi)(qi)(qi)中(zhong)的(de)粉(fen)塵，它的(de)凈化工作上要是依(yi)靠電(dian)(dian)(dian)(dian)(dian)暈(yun)極和(he)沉(chen)(chen)淀兩個系統來完成的(de)，當含塵氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)進(jin)人(ren)(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭時，含塵氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)受(shou)到氣(qi)(qi)(qi)(qi)(qi)流(liu)分(fen)布板(ban)(ban)以(yi)及折流(liu)板(ban)(ban)的(de)調(diao)整后，使(shi)氣(qi)(qi)(qi)(qi)(qi)流(liu)能較(jiao)均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)。在(zai)(zai)(zai)橫斷(duan)面擴大的(de)作用下，氣(qi)(qi)(qi)(qi)(qi)流(liu)速(su)(su)度迅速(su)(su)降(jiang)低，其中(zhong)有些(xie)(xie)較(jiao)重的(de)塵粒(li)(li)便(bian)失去速(su)(su)度而沉(chen)(chen)降(jiang)下來。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)含塵氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極通(tong)人(ren)(ren)高壓(ya)(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后的(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)存在(zai)(zai)(zai)大量(liang)的(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)，這些(xie)(xie)電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi)與進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)粉(fen)塵結合起(qi)來，使(shi)塵粒(li)(li)帶電(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)塵粒(li)(li)在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)作用下趨向本設備陽極(正(zheng)極、本設備采用負(fu)高壓(ya)(ya)制)和(he)陰極(負(fu)極) ， 釋放出電(dian)(dian)(dian)(dian)(dian)子(zi)分(fen)別沉(chen)(chen)積在(zai)(zai)(zai)相應的(de)電(dian)(dian)(dian)(dian)(dian)極上，通(tong)過設備陰陽極振打(da)系統的(de)振打(da)，使(shi)沉(chen)(chen)積在(zai)(zai)(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極上的(de)粉(fen)塵振落，進(jin)人(ren)(ren)集灰斗 通(tong)過排灰裝置放出，回(hui)收有物料，被)凈化的(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)排入大氣(qi)(qi)(qi)(qi)(qi)。

工(gong)作原理

靜電(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)工作原理(li)是利用高(gao)壓電(dian)(dian)場使(shi)煙(yan)氣(qi)(qi)發生(sheng)電(dian)(dian)離(li)，氣(qi)(qi)流(liu)(liu)中的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)在電(dian)(dian)場作用下與氣(qi)(qi)流(liu)(liu)分離(li)。負極由不(bu)同斷(duan)面形狀的(de)(de)(de)金屬(shu)導線制(zhi)成(cheng)，叫放電(dian)(dian)電(dian)(dian)極。正(zheng)極由不(bu)同幾何形狀的(de)(de)(de)金屬(shu)板制(zhi)成(cheng)，叫集(ji)塵(chen)(chen)(chen)電(dian)(dian)極。靜電(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)質、設備構造和煙(yan)氣(qi)(qi)流(liu)(liu)速等(deng)三個因素的(de)(de)(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)阻(zu)是評價導電(dian)(dian)性(xing)的(de)(de)(de)指標(biao)，它對除塵(chen)(chen)(chen)效率有(you)直接的(de)(de)(de)影響。比電(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)極上，致使(shi)其重返(fan)氣(qi)(qi)流(liu)(liu)。比電(dian)(dian)阻(zu)過(guo)高(gao)，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)極的(de)(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷(he)不(bu)易放出，在塵(chen)(chen)(chen)層(ceng)之(zhi)間形成(cheng)電(dian)(dian)壓梯度會產(chan)生(sheng)局部擊穿和放電(dian)(dian)現象。這些情況(kuang)都會造成(cheng)除塵(chen)(chen)(chen)效率下降(jiang)。

電除塵(chen)(chen)器的基本原理是(shi)利(li)用電力(li)捕集(ji)煙氣中(zhong)的粉塵(chen)(chen)，主要包括以下(xia)四(si)個(ge)相(xiang)互有(you)關的物理過程(cheng): (1) 氣體的電離(li)。(2) 粉塵(chen)(chen)的荷電。(3) 荷電粉塵(chen)(chen)向電極移動(dong)。(4) 荷電粉塵(chen)(chen)的捕集(ji)。
