長春靜電除塵器廠家

靜電除塵器的工作原(yuan)理是(shi)利用(yong)高壓電(dian)(dian)(dian)場使(shi)煙氣發生電(dian)(dian)(dian)離，氣流(liu)中的粉塵荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用(yong)下與氣流(liu)分離。負極由不(bu)同斷(duan)面形狀(zhuang)的金屬導線制(zhi)成，叫放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)極。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的(de)性(xing)能(neng)受粉塵(chen)(chen)性(xing)質、設備構造(zao)和煙(yan)氣流速(su)等(deng)三個因素的(de)影響。粉塵(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)阻(zu)是(shi)評價(jia)導(dao)電(dian)(dian)(dian)性(xing)的(de)指標，它(ta)對(dui)除塵(chen)(chen)效率有直接的(de)影響。比(bi)電(dian)(dian)(dian)阻(zu)過低，塵(chen)(chen)粒難以(yi)保(bao)持在(zai)集塵(chen)(chen)電(dian)(dian)(dian)極上，致使其重返氣流。比(bi)電(dian)(dian)(dian)阻(zu)過高(gao)，到達集塵(chen)(chen)電(dian)(dian)(dian)極的(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不易放出，在(zai)塵(chen)(chen)層之間形成電(dian)(dian)(dian)壓梯(ti)度會產生局部(bu)擊穿和放電(dian)(dian)(dian)現象(xiang)。這些情(qing)況都會造(zao)成除塵(chen)(chen)效率下降。

簡介

靜電除塵器的電源由控制箱、升壓變壓器和整流器組成。電源輸出的電壓高低對除塵效率也有很大影響。因此，靜電除塵器運行電壓(ya)需保持40一75kV乃(nai)至100kV以上。

工作原理

電(dian)除塵(chen)(chen)器(qi)的(de)(de)基(ji)本原理(li)是利(li)用(yong)電(dian)力捕(bu)(bu)集煙氣(qi)中的(de)(de)粉塵(chen)(chen)，主要(yao)包括以下四個(ge)相互有關的(de)(de)物(wu)理(li)過程：（1）氣(qi)體的(de)(de)電(dian)離。（2）粉塵(chen)(chen)的(de)(de)荷(he)(he)電(dian)。（3）荷(he)(he)電(dian)粉塵(chen)(chen)向電(dian)極移動。（4）荷(he)(he)電(dian)粉塵(chen)(chen)的(de)(de)捕(bu)(bu)集。

荷電(dian)(dian)(dian)(dian)粉(fen)(fen)(fen)塵(chen)(chen)的(de)(de)(de)捕集過(guo)程：在兩個曲率半徑(jing)相差(cha)較大的(de)(de)(de)金屬(shu)陽極(ji)和(he)陰極(ji)上，通過(guo)高壓直流電(dian)(dian)(dian)(dian)，維持一個足以使氣體(ti)電(dian)(dian)(dian)(dian)離(li)(li)(li)的(de)(de)(de)電(dian)(dian)(dian)(dian)場(chang)(chang)，氣體(ti)電(dian)(dian)(dian)(dian)離(li)(li)(li)后所產生的(de)(de)(de)電(dian)(dian)(dian)(dian)子：陰離(li)(li)(li)子和(he)陽離(li)(li)(li)子，吸附在通過(guo)電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉(fen)(fen)(fen)塵(chen)(chen)上，使粉(fen)(fen)(fen)塵(chen)(chen)獲得電(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)極(ji)性不同(tong)的(de)(de)(de)粉(fen)(fen)(fen)塵(chen)(chen)在電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)作用(yong)下(xia)，分別(bie)向不同(tong)極(ji)性的(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)運(yun)動(dong)，沉積在電(dian)(dian)(dian)(dian)極(ji)上，而達到粉(fen)(fen)(fen)塵(chen)(chen)和(he)氣體(ti)分離(li)(li)(li)的(de)(de)(de)目的(de)(de)(de)。

基本結構

靜電(dian)(dian)電(dian)(dian)除塵(chen)(chen)器由兩(liang)大部(bu)(bu)分(fen)組成：一(yi)部(bu)(bu)分(fen)是電(dian)(dian)除塵(chen)(chen)器本體系(xi)統；另一(yi)部(bu)(bu)分(fen)是提供(gong)高壓(ya)(ya)直流(liu)電(dian)(dian)的供(gong)電(dian)(dian)裝置和低壓(ya)(ya)自動控制系(xi)統。電(dian)(dian)除塵(chen)(chen)器的結構原理圖如圖1所示，高壓(ya)(ya)供(gong)電(dian)(dian)系(xi)統為升壓(ya)(ya)變壓(ya)(ya)器供(gong)電(dian)(dian)，除塵(chen)(chen)器集塵(chen)(chen)極接地(di)。低壓(ya)(ya)電(dian)(dian)控制系(xi)統用來控制電(dian)(dian)磁振(zhen)打錘、卸灰(hui)電(dian)(dian)極、輸灰(hui)電(dian)(dian)極以及幾個部(bu)(bu)件的溫(wen)度。
