棗莊靜電除塵器廠家

靜電除塵器的工作原(yuan)理是利用(yong)高(gao)壓電(dian)場使煙(yan)氣發(fa)生(sheng)電(dian)離(li)，氣流中的粉塵(chen)荷電(dian)在電(dian)場作用(yong)下與氣流分(fen)離(li)。負極由不同斷面(mian)形狀的金屬導線制成，叫放電(dian)電(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)(de)性能(neng)受粉塵(chen)(chen)(chen)(chen)性質、設備構(gou)造(zao)和煙氣流速等三個因(yin)素的(de)(de)影響。粉塵(chen)(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)阻(zu)(zu)是(shi)評(ping)價導電(dian)(dian)性的(de)(de)指標，它對(dui)除塵(chen)(chen)(chen)(chen)效率有(you)直接的(de)(de)影響。比(bi)電(dian)(dian)阻(zu)(zu)過(guo)低，塵(chen)(chen)(chen)(chen)粒難(nan)以保持在集塵(chen)(chen)(chen)(chen)電(dian)(dian)極上(shang)，致使其重(zhong)返氣流。比(bi)電(dian)(dian)阻(zu)(zu)過(guo)高，到(dao)達集塵(chen)(chen)(chen)(chen)電(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)易放出(chu)，在塵(chen)(chen)(chen)(chen)層之(zhi)間形(xing)成(cheng)電(dian)(dian)壓梯度會產生(sheng)局部擊穿和放電(dian)(dian)現象(xiang)。這些(xie)情況都會造(zao)成(cheng)除塵(chen)(chen)(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(bao)持40一(yi)75kV乃至100kV以上。

工作原理

電(dian)(dian)除(chu)塵(chen)器的基(ji)本原理(li)是利用電(dian)(dian)力(li)捕(bu)集煙氣中的粉(fen)塵(chen)，主要包括以下四個相(xiang)互(hu)有關的物理(li)過程：（1）氣體的電(dian)(dian)離。（2）粉(fen)塵(chen)的荷電(dian)(dian)。（3）荷電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動。（4）荷電(dian)(dian)粉(fen)塵(chen)的捕(bu)集。

荷電(dian)(dian)(dian)(dian)(dian)粉(fen)(fen)塵(chen)的(de)(de)(de)(de)(de)捕集過(guo)程：在兩個(ge)曲率半徑相差較大(da)的(de)(de)(de)(de)(de)金屬(shu)陽(yang)極和(he)陰極上，通過(guo)高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)，維持一個(ge)足以使氣體電(dian)(dian)(dian)(dian)(dian)離(li)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)場，氣體電(dian)(dian)(dian)(dian)(dian)離(li)后所(suo)產生(sheng)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子：陰離(li)子和(he)陽(yang)離(li)子，吸附在通過(guo)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)(de)粉(fen)(fen)塵(chen)上，使粉(fen)(fen)塵(chen)獲得(de)電(dian)(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)(dian)極性不同的(de)(de)(de)(de)(de)粉(fen)(fen)塵(chen)在電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)(de)作(zuo)用(yong)下(xia)，分別(bie)向不同極性的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極運動，沉積在電(dian)(dian)(dian)(dian)(dian)極上，而達到粉(fen)(fen)塵(chen)和(he)氣體分離(li)的(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)。

靜電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)除(chu)塵器(qi)(qi)由(you)兩大部(bu)(bu)分組成：一部(bu)(bu)分是電(dian)(dian)(dian)(dian)除(chu)塵器(qi)(qi)本體系(xi)統(tong)；另一部(bu)(bu)分是提供高壓(ya)直(zhi)流(liu)電(dian)(dian)(dian)(dian)的供電(dian)(dian)(dian)(dian)裝置和(he)低壓(ya)自動控制系(xi)統(tong)。電(dian)(dian)(dian)(dian)除(chu)塵器(qi)(qi)的結構原(yuan)理圖(tu)如圖(tu)1所示(shi)，高壓(ya)供電(dian)(dian)(dian)(dian)系(xi)統(tong)為升壓(ya)變壓(ya)器(qi)(qi)供電(dian)(dian)(dian)(dian)，除(chu)塵器(qi)(qi)集(ji)塵極(ji)接地。低壓(ya)電(dian)(dian)(dian)(dian)控制系(xi)統(tong)用(yong)來控制電(dian)(dian)(dian)(dian)磁振打錘(chui)、卸灰電(dian)(dian)(dian)(dian)極(ji)、輸灰電(dian)(dian)(dian)(dian)極(ji)以及幾個部(bu)(bu)件的溫度(du)。
