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)除塵器是以(yi)靜(jing)電(dian)(dian)(dian)凈化法來(lai)收捕廢氣(qi)中的(de)(de)(de)粉塵，它的(de)(de)(de)凈化工作(zuo)(zuo)上要是依(yi)靠電(dian)(dian)(dian)暈(yun)極(ji)和(he)(he)沉(chen)淀兩個系(xi)(xi)統來(lai)完(wan)成的(de)(de)(de)，當(dang)含(han)(han)塵氣(qi)體(ti)進(jin)人(ren)氣(qi)刺叭時，含(han)(han)塵氣(qi)體(ti)受到氣(qi)流(liu)(liu)(liu)分布(bu)板(ban)以(yi)及折(zhe)流(liu)(liu)(liu)板(ban)的(de)(de)(de)調整后(hou)，使氣(qi)流(liu)(liu)(liu)能較均勻地進(jin)人(ren)電(dian)(dian)(dian)場(chang)(chang)。在橫斷面(mian)擴(kuo)大(da)的(de)(de)(de)作(zuo)(zuo)用(yong)(yong)下，氣(qi)流(liu)(liu)(liu)速度(du)迅速降低，其中有些較重的(de)(de)(de)塵粒便失去速度(du)而(er)沉(chen)降下來(lai)。進(jin)人(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)含(han)(han)塵氣(qi)體(ti)由于(yu)電(dian)(dian)(dian)暈(yun)極(ji)通(tong)(tong)人(ren)高壓直流(liu)(liu)(liu)電(dian)(dian)(dian)，則在電(dian)(dian)(dian)暈(yun)極(ji)附近產生(sheng)電(dian)(dian)(dian)暈(yun)現象，使氣(qi)體(ti)電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后(hou)的(de)(de)(de)氣(qi)體(ti)中存在大(da)量的(de)(de)(de)電(dian)(dian)(dian)子和(he)(he)離子，這(zhe)些電(dian)(dian)(dian)子和(he)(he)離子與進(jin)人(ren)電(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉塵結合起來(lai)，使塵粒帶(dai)(dai)電(dian)(dian)(dian)，帶(dai)(dai)電(dian)(dian)(dian)塵粒在電(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)作(zuo)(zuo)用(yong)(yong)下趨向(xiang)本(ben)設(she)備(bei)(bei)陽極(ji)(正極(ji)、本(ben)設(she)備(bei)(bei)采用(yong)(yong)負(fu)高壓制)和(he)(he)陰(yin)極(ji)(負(fu)極(ji)) ， 釋放(fang)出電(dian)(dian)(dian)子分別沉(chen)積在相應的(de)(de)(de)電(dian)(dian)(dian)極(ji)上，通(tong)(tong)過(guo)設(she)備(bei)(bei)陰(yin)陽極(ji)振打系(xi)(xi)統的(de)(de)(de)振打，使沉(chen)積在陰(yin)陽電(dian)(dian)(dian)極(ji)上的(de)(de)(de)粉塵振落，進(jin)人(ren)集灰(hui)斗 通(tong)(tong)過(guo)排灰(hui)裝置放(fang)出，回收有物料，被(bei))凈化的(de)(de)(de)氣(qi)體(ti)排入大(da)氣(qi)。

工作原理

靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)工(gong)作原理是(shi)利(li)用(yong)高壓電(dian)(dian)場(chang)使煙氣(qi)(qi)發(fa)生(sheng)電(dian)(dian)離(li)，氣(qi)(qi)流(liu)(liu)中(zhong)的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)荷電(dian)(dian)在(zai)(zai)電(dian)(dian)場(chang)作用(yong)下與氣(qi)(qi)流(liu)(liu)分離(li)。負極(ji)由不同(tong)斷面形(xing)(xing)狀的(de)(de)金屬導(dao)線(xian)制成(cheng)，叫放電(dian)(dian)電(dian)(dian)極(ji)。正極(ji)由不同(tong)幾何形(xing)(xing)狀的(de)(de)金屬板制成(cheng)，叫集塵(chen)(chen)(chen)電(dian)(dian)極(ji)。靜電(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)(de)性能受粉(fen)(fen)塵(chen)(chen)(chen)性質、設備構(gou)造和(he)煙氣(qi)(qi)流(liu)(liu)速等三個因素的(de)(de)影(ying)響。粉(fen)(fen)塵(chen)(chen)(chen)的(de)(de)比(bi)(bi)電(dian)(dian)阻是(shi)評價導(dao)電(dian)(dian)性的(de)(de)指標，它(ta)對除(chu)塵(chen)(chen)(chen)效(xiao)率有直接的(de)(de)影(ying)響。比(bi)(bi)電(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難(nan)以保持在(zai)(zai)集塵(chen)(chen)(chen)電(dian)(dian)極(ji)上，致(zhi)使其重(zhong)返氣(qi)(qi)流(liu)(liu)。比(bi)(bi)電(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷不易放出，在(zai)(zai)塵(chen)(chen)(chen)層之間形(xing)(xing)成(cheng)電(dian)(dian)壓梯度會產生(sheng)局部(bu)擊穿和(he)放電(dian)(dian)現象。這(zhe)些情況都會造成(cheng)除(chu)塵(chen)(chen)(chen)效(xiao)率下降。

電(dian)(dian)除(chu)塵(chen)器的基本原理(li)是利用電(dian)(dian)力捕集煙(yan)氣中的粉(fen)塵(chen)，主要包括以(yi)下四個相互有關(guan)的物理(li)過程(cheng): (1) 氣體的電(dian)(dian)離。(2) 粉(fen)塵(chen)的荷(he)電(dian)(dian)。(3) 荷(he)電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動。(4) 荷(he)電(dian)(dian)粉(fen)塵(chen)的捕集。
