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(shi)靜電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器是以靜電(dian)(dian)(dian)凈(jing)化法來(lai)(lai)收(shou)捕廢(fei)氣(qi)(qi)中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)，它的(de)(de)凈(jing)化工作上(shang)(shang)要是依靠(kao)電(dian)(dian)(dian)暈(yun)極(ji)和沉淀兩個系(xi)統來(lai)(lai)完成的(de)(de)，當含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)進人(ren)氣(qi)(qi)刺叭(ba)時，含(han)塵(chen)(chen)(chen)(chen)氣(qi)(qi)體(ti)(ti)受到氣(qi)(qi)流(liu)(liu)分(fen)布(bu)板(ban)以及折(zhe)流(liu)(liu)板(ban)的(de)(de)調整后(hou)，使(shi)氣(qi)(qi)流(liu)(liu)能(neng)較(jiao)均勻地進人(ren)電(dian)(dian)(dian)場(chang)(chang)。在(zai)(zai)橫斷面(mian)擴大(da)的(de)(de)作用(yong)下(xia)，氣(qi)(qi)流(liu)(liu)速度迅(xun)速降低，其中有(you)些(xie)較(jiao)重的(de)(de)塵(chen)(chen)(chen)(chen)粒便(bian)失去速度而沉降下(xia)來(lai)(lai)。進人(ren)電(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)暈(yun)極(ji)通(tong)人(ren)高壓(ya)直(zhi)流(liu)(liu)電(dian)(dian)(dian)，則在(zai)(zai)電(dian)(dian)(dian)暈(yun)極(ji)附(fu)近(jin)產生(sheng)電(dian)(dian)(dian)暈(yun)現(xian)象，使(shi)氣(qi)(qi)體(ti)(ti)電(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)離(li)后(hou)的(de)(de)氣(qi)(qi)體(ti)(ti)中存在(zai)(zai)大(da)量的(de)(de)電(dian)(dian)(dian)子(zi)和離(li)子(zi)，這些(xie)電(dian)(dian)(dian)子(zi)和離(li)子(zi)與進人(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)結合起來(lai)(lai)，使(shi)塵(chen)(chen)(chen)(chen)粒帶電(dian)(dian)(dian)，帶電(dian)(dian)(dian)塵(chen)(chen)(chen)(chen)粒在(zai)(zai)電(dian)(dian)(dian)場(chang)(chang)力(li)的(de)(de)作用(yong)下(xia)趨(qu)向本設(she)(she)(she)備(bei)(bei)陽極(ji)(正極(ji)、本設(she)(she)(she)備(bei)(bei)采用(yong)負高壓(ya)制(zhi))和陰(yin)極(ji)(負極(ji)) ， 釋放出電(dian)(dian)(dian)子(zi)分(fen)別沉積在(zai)(zai)相應的(de)(de)電(dian)(dian)(dian)極(ji)上(shang)(shang)，通(tong)過(guo)設(she)(she)(she)備(bei)(bei)陰(yin)陽極(ji)振(zhen)打系(xi)統的(de)(de)振(zhen)打，使(shi)沉積在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)極(ji)上(shang)(shang)的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)振(zhen)落，進人(ren)集灰斗 通(tong)過(guo)排灰裝置(zhi)放出，回(hui)收(shou)有(you)物料，被)凈(jing)化的(de)(de)氣(qi)(qi)體(ti)(ti)排入大(da)氣(qi)(qi)。

工作原(yuan)理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器的(de)工作(zuo)原(yuan)理是利用高(gao)壓電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣發生(sheng)電(dian)(dian)(dian)(dian)(dian)離，氣流中(zhong)的(de)粉(fen)(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)在(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作(zuo)用下與氣流分(fen)離。負(fu)極(ji)(ji)由(you)不(bu)同斷面(mian)形狀的(de)金(jin)屬導線制(zhi)成，叫放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。正(zheng)極(ji)(ji)由(you)不(bu)同幾何形狀的(de)金(jin)屬板(ban)制(zhi)成，叫集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。靜電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器的(de)性能受粉(fen)(fen)塵(chen)(chen)(chen)性質(zhi)、設(she)備構造和(he)煙氣流速(su)等三個因素的(de)影響。粉(fen)(fen)塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)(dian)(dian)性的(de)指標，它對除(chu)(chu)(chu)塵(chen)(chen)(chen)效率有直接(jie)的(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以保(bao)持在(zai)(zai)(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返(fan)氣流。比電(dian)(dian)(dian)(dian)(dian)阻過高(gao)，到達(da)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷(he)不(bu)易放(fang)(fang)出，在(zai)(zai)(zai)塵(chen)(chen)(chen)層之間形成電(dian)(dian)(dian)(dian)(dian)壓梯(ti)度會產生(sheng)局部擊穿和(he)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)現象。這些(xie)情況都會造成除(chu)(chu)(chu)塵(chen)(chen)(chen)效率下降(jiang)。

電(dian)(dian)除(chu)塵器的基本原(yuan)理是利(li)用電(dian)(dian)力捕(bu)(bu)集煙氣(qi)中的粉(fen)塵，主要包括以(yi)下四個相互有關的物理過程: (1) 氣(qi)體(ti)的電(dian)(dian)離。(2) 粉(fen)塵的荷電(dian)(dian)。(3) 荷電(dian)(dian)粉(fen)塵向電(dian)(dian)極移(yi)動。(4) 荷電(dian)(dian)粉(fen)塵的捕(bu)(bu)集。
