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)除塵(chen)(chen)(chen)器是以靜電(dian)凈化(hua)(hua)法來(lai)收(shou)捕廢(fei)氣(qi)(qi)(qi)(qi)(qi)中的(de)(de)粉塵(chen)(chen)(chen)，它的(de)(de)凈化(hua)(hua)工作(zuo)上(shang)要是依靠電(dian)暈(yun)極(ji)和沉(chen)(chen)(chen)淀兩個系(xi)統來(lai)完成的(de)(de)，當含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)進(jin)人(ren)(ren)(ren)氣(qi)(qi)(qi)(qi)(qi)刺叭(ba)時(shi)，含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)受到氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)分(fen)布板以及折(zhe)流(liu)(liu)板的(de)(de)調整后，使(shi)氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)能較均勻地進(jin)人(ren)(ren)(ren)電(dian)場。在(zai)(zai)橫斷面擴大(da)(da)的(de)(de)作(zuo)用(yong)下(xia)，氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)速度迅速降(jiang)(jiang)低(di)，其中有(you)些(xie)較重的(de)(de)塵(chen)(chen)(chen)粒便失去速度而沉(chen)(chen)(chen)降(jiang)(jiang)下(xia)來(lai)。進(jin)人(ren)(ren)(ren)電(dian)場的(de)(de)含塵(chen)(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)由(you)于電(dian)暈(yun)極(ji)通人(ren)(ren)(ren)高(gao)壓直流(liu)(liu)電(dian)，則(ze)在(zai)(zai)電(dian)暈(yun)極(ji)附近產生電(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)電(dian)離，電(dian)離后的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)中存在(zai)(zai)大(da)(da)量的(de)(de)電(dian)子(zi)(zi)(zi)和離子(zi)(zi)(zi)，這些(xie)電(dian)子(zi)(zi)(zi)和離子(zi)(zi)(zi)與進(jin)人(ren)(ren)(ren)電(dian)場的(de)(de)粉塵(chen)(chen)(chen)結(jie)合起來(lai)，使(shi)塵(chen)(chen)(chen)粒帶電(dian)，帶電(dian)塵(chen)(chen)(chen)粒在(zai)(zai)電(dian)場力(li)的(de)(de)作(zuo)用(yong)下(xia)趨向本(ben)設(she)備陽(yang)極(ji)(正極(ji)、本(ben)設(she)備采(cai)用(yong)負高(gao)壓制)和陰極(ji)(負極(ji)) ， 釋放出電(dian)子(zi)(zi)(zi)分(fen)別(bie)沉(chen)(chen)(chen)積在(zai)(zai)相應的(de)(de)電(dian)極(ji)上(shang)，通過設(she)備陰陽(yang)極(ji)振(zhen)(zhen)打系(xi)統的(de)(de)振(zhen)(zhen)打，使(shi)沉(chen)(chen)(chen)積在(zai)(zai)陰陽(yang)電(dian)極(ji)上(shang)的(de)(de)粉塵(chen)(chen)(chen)振(zhen)(zhen)落，進(jin)人(ren)(ren)(ren)集灰斗 通過排灰裝置放出，回(hui)收(shou)有(you)物料，被(bei))凈化(hua)(hua)的(de)(de)氣(qi)(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)排入大(da)(da)氣(qi)(qi)(qi)(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)工(gong)作原理是(shi)利用高(gao)壓電(dian)(dian)(dian)(dian)場(chang)(chang)使(shi)煙(yan)氣(qi)發生(sheng)電(dian)(dian)(dian)(dian)離(li)，氣(qi)流中(zhong)的(de)(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)在(zai)(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)作用下(xia)與(yu)氣(qi)流分離(li)。負極(ji)(ji)由不同(tong)斷面形狀(zhuang)的(de)(de)金屬(shu)導線制成，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)極(ji)(ji)。正極(ji)(ji)由不同(tong)幾何形狀(zhuang)的(de)(de)金屬(shu)板制成，叫(jiao)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)性(xing)質、設備構造和煙(yan)氣(qi)流速(su)等三個因素的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)(dian)阻是(shi)評(ping)價導電(dian)(dian)(dian)(dian)性(xing)的(de)(de)指(zhi)標，它對除(chu)塵(chen)(chen)(chen)效率有(you)直接的(de)(de)影響。比電(dian)(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)(chen)粒(li)難以保(bao)持在(zai)(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，致(zhi)使(shi)其重返(fan)氣(qi)流。比電(dian)(dian)(dian)(dian)阻過(guo)高(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)荷不易(yi)放(fang)出，在(zai)(zai)塵(chen)(chen)(chen)層之間形成電(dian)(dian)(dian)(dian)壓梯度(du)會產生(sheng)局部擊穿和放(fang)電(dian)(dian)(dian)(dian)現象(xiang)。這(zhe)些情況都會造成除(chu)塵(chen)(chen)(chen)效率下(xia)降。

電除塵器(qi)的(de)基本原理(li)是利用電力(li)捕(bu)集煙氣中的(de)粉塵，主要包括以下(xia)四個相互有關的(de)物(wu)理(li)過程: (1) 氣體的(de)電離。(2) 粉塵的(de)荷(he)(he)電。(3) 荷(he)(he)電粉塵向電極(ji)移動。(4) 荷(he)(he)電粉塵的(de)捕(bu)集。
