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)(dian)除塵(chen)(chen)(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)凈化(hua)(hua)(hua)法來收捕廢氣(qi)(qi)中(zhong)的(de)(de)粉塵(chen)(chen)(chen)(chen)，它(ta)的(de)(de)凈化(hua)(hua)(hua)工作上要是依靠電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)和沉淀兩個系統來完(wan)成的(de)(de)，當(dang)含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進(jin)人氣(qi)(qi)刺叭時(shi)，含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流(liu)分(fen)布板以(yi)及折(zhe)流(liu)板的(de)(de)調整(zheng)后(hou)，使(shi)氣(qi)(qi)流(liu)能較均勻地進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)。在橫斷面擴大的(de)(de)作用(yong)下，氣(qi)(qi)流(liu)速度迅速降(jiang)低，其中(zhong)有些較重的(de)(de)塵(chen)(chen)(chen)(chen)粒(li)便失去速度而沉降(jiang)下來。進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)通(tong)人高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)(ji)(ji)(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈現(xian)象，使(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)離(li)(li)后(hou)的(de)(de)氣(qi)(qi)體(ti)(ti)中(zhong)存在大量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和離(li)(li)子，這些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子和離(li)(li)子與(yu)進(jin)人電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)粉塵(chen)(chen)(chen)(chen)結合(he)起(qi)來，使(shi)塵(chen)(chen)(chen)(chen)粒(li)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)作用(yong)下趨(qu)向本設(she)(she)備陽極(ji)(ji)(ji)(ji)(ji)(正(zheng)極(ji)(ji)(ji)(ji)(ji)、本設(she)(she)備采用(yong)負(fu)(fu)高壓(ya)制)和陰極(ji)(ji)(ji)(ji)(ji)(負(fu)(fu)極(ji)(ji)(ji)(ji)(ji)) ， 釋(shi)放出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子分(fen)別沉積(ji)在相應的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上，通(tong)過(guo)設(she)(she)備陰陽極(ji)(ji)(ji)(ji)(ji)振打系統的(de)(de)振打，使(shi)沉積(ji)在陰陽電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)(ji)(ji)上的(de)(de)粉塵(chen)(chen)(chen)(chen)振落，進(jin)人集灰斗(dou) 通(tong)過(guo)排(pai)灰裝(zhuang)置放出，回收有物料，被(bei))凈化(hua)(hua)(hua)的(de)(de)氣(qi)(qi)體(ti)(ti)排(pai)入大氣(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)工作原理(li)是(shi)利(li)用(yong)高(gao)壓(ya)電(dian)(dian)場使煙(yan)氣(qi)(qi)發生(sheng)(sheng)電(dian)(dian)離，氣(qi)(qi)流(liu)中的(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)在電(dian)(dian)場作用(yong)下(xia)與氣(qi)(qi)流(liu)分離。負極(ji)由不同(tong)斷(duan)面形(xing)(xing)狀的(de)金(jin)屬(shu)導線(xian)制(zhi)成，叫放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不同(tong)幾(ji)何形(xing)(xing)狀的(de)金(jin)屬(shu)板制(zhi)成，叫集塵(chen)(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的(de)性(xing)能受(shou)粉塵(chen)(chen)(chen)性(xing)質、設(she)備構造和煙(yan)氣(qi)(qi)流(liu)速等三個因(yin)素(su)的(de)影(ying)響(xiang)。粉塵(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)阻是(shi)評價(jia)導電(dian)(dian)性(xing)的(de)指標，它(ta)對除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率(lv)有直接(jie)的(de)影(ying)響(xiang)。比(bi)電(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒(li)難以保持在集塵(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使其重返氣(qi)(qi)流(liu)。比(bi)電(dian)(dian)阻過(guo)高(gao)，到(dao)達集塵(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)荷不易放出，在塵(chen)(chen)(chen)層之間形(xing)(xing)成電(dian)(dian)壓(ya)梯(ti)度會(hui)產生(sheng)(sheng)局部擊穿和放電(dian)(dian)現象。這些情(qing)況都會(hui)造成除(chu)(chu)塵(chen)(chen)(chen)效(xiao)率(lv)下(xia)降。

電(dian)除(chu)塵(chen)器的(de)基本(ben)原理(li)是利(li)用電(dian)力捕(bu)集煙氣中的(de)粉(fen)塵(chen)，主要包括以下四個相互有關的(de)物理(li)過程: (1) 氣體(ti)的(de)電(dian)離。(2) 粉(fen)塵(chen)的(de)荷(he)電(dian)。(3) 荷(he)電(dian)粉(fen)塵(chen)向電(dian)極移動。(4) 荷(he)電(dian)粉(fen)塵(chen)的(de)捕(bu)集。
