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)除塵(chen)(chen)器是以(yi)靜電(dian)(dian)(dian)凈(jing)化法來(lai)(lai)收捕廢氣(qi)(qi)(qi)中的(de)(de)粉塵(chen)(chen)，它的(de)(de)凈(jing)化工作上要是依靠電(dian)(dian)(dian)暈(yun)極(ji)(ji)和沉(chen)淀(dian)兩個系統(tong)來(lai)(lai)完成的(de)(de)，當含(han)塵(chen)(chen)氣(qi)(qi)(qi)體進(jin)(jin)人(ren)氣(qi)(qi)(qi)刺叭(ba)時，含(han)塵(chen)(chen)氣(qi)(qi)(qi)體受到氣(qi)(qi)(qi)流(liu)(liu)分(fen)布板(ban)(ban)以(yi)及折流(liu)(liu)板(ban)(ban)的(de)(de)調整后，使(shi)氣(qi)(qi)(qi)流(liu)(liu)能較均勻地(di)進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)。在(zai)橫(heng)斷面擴大的(de)(de)作用下，氣(qi)(qi)(qi)流(liu)(liu)速度迅速降低，其(qi)中有些較重的(de)(de)塵(chen)(chen)粒便失(shi)去速度而沉(chen)降下來(lai)(lai)。進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)含(han)塵(chen)(chen)氣(qi)(qi)(qi)體由于電(dian)(dian)(dian)暈(yun)極(ji)(ji)通人(ren)高(gao)壓直流(liu)(liu)電(dian)(dian)(dian)，則在(zai)電(dian)(dian)(dian)暈(yun)極(ji)(ji)附近(jin)產生(sheng)電(dian)(dian)(dian)暈(yun)現象，使(shi)氣(qi)(qi)(qi)體電(dian)(dian)(dian)離，電(dian)(dian)(dian)離后的(de)(de)氣(qi)(qi)(qi)體中存在(zai)大量的(de)(de)電(dian)(dian)(dian)子和離子，這(zhe)些電(dian)(dian)(dian)子和離子與(yu)進(jin)(jin)人(ren)電(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)結合起來(lai)(lai)，使(shi)塵(chen)(chen)粒帶(dai)(dai)電(dian)(dian)(dian)，帶(dai)(dai)電(dian)(dian)(dian)塵(chen)(chen)粒在(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)作用下趨向本(ben)設備陽極(ji)(ji)(正極(ji)(ji)、本(ben)設備采用負(fu)高(gao)壓制)和陰極(ji)(ji)(負(fu)極(ji)(ji)) ， 釋放(fang)出(chu)電(dian)(dian)(dian)子分(fen)別沉(chen)積在(zai)相應的(de)(de)電(dian)(dian)(dian)極(ji)(ji)上，通過設備陰陽極(ji)(ji)振打系統(tong)的(de)(de)振打，使(shi)沉(chen)積在(zai)陰陽電(dian)(dian)(dian)極(ji)(ji)上的(de)(de)粉塵(chen)(chen)振落，進(jin)(jin)人(ren)集灰斗 通過排灰裝置(zhi)放(fang)出(chu)，回收有物料，被(bei))凈(jing)化的(de)(de)氣(qi)(qi)(qi)體排入大氣(qi)(qi)(qi)。

工作原理(li)

靜(jing)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)工作(zuo)原理是利用高壓(ya)(ya)電(dian)(dian)場使煙氣發生電(dian)(dian)離(li)，氣流中的(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)在(zai)電(dian)(dian)場作(zuo)用下與氣流分離(li)。負極(ji)(ji)(ji)由(you)不(bu)(bu)同(tong)(tong)斷面形狀(zhuang)的(de)(de)金(jin)屬導線制成(cheng)，叫放(fang)電(dian)(dian)電(dian)(dian)極(ji)(ji)(ji)。正(zheng)極(ji)(ji)(ji)由(you)不(bu)(bu)同(tong)(tong)幾何形狀(zhuang)的(de)(de)金(jin)屬板制成(cheng)，叫集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)。靜(jing)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)性(xing)能受粉(fen)塵(chen)(chen)(chen)(chen)性(xing)質、設備構造和(he)煙氣流速等三個因(yin)素的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)(de)比電(dian)(dian)阻是評價導電(dian)(dian)性(xing)的(de)(de)指(zhi)標(biao)，它對除(chu)(chu)塵(chen)(chen)(chen)(chen)效率有直接的(de)(de)影響。比電(dian)(dian)阻過(guo)(guo)低(di)，塵(chen)(chen)(chen)(chen)粒難以保(bao)持(chi)在(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)上(shang)，致(zhi)使其(qi)重返(fan)氣流。比電(dian)(dian)阻過(guo)(guo)高，到達集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)(ji)(ji)的(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)(bu)易放(fang)出(chu)，在(zai)塵(chen)(chen)(chen)(chen)層(ceng)之間(jian)形成(cheng)電(dian)(dian)壓(ya)(ya)梯度會(hui)產生局部(bu)擊穿(chuan)和(he)放(fang)電(dian)(dian)現(xian)象。這些情況都會(hui)造成(cheng)除(chu)(chu)塵(chen)(chen)(chen)(chen)效率下降。

電(dian)(dian)(dian)除塵(chen)(chen)器(qi)的基本原理是利用電(dian)(dian)(dian)力捕集煙(yan)氣(qi)中(zhong)的粉(fen)塵(chen)(chen)，主要包(bao)括以(yi)下四個(ge)相(xiang)互(hu)有(you)關的物(wu)理過程: (1) 氣(qi)體的電(dian)(dian)(dian)離(li)。(2) 粉(fen)塵(chen)(chen)的荷(he)(he)電(dian)(dian)(dian)。(3) 荷(he)(he)電(dian)(dian)(dian)粉(fen)塵(chen)(chen)向電(dian)(dian)(dian)極移動。(4) 荷(he)(he)電(dian)(dian)(dian)粉(fen)塵(chen)(chen)的捕集。
