澳門靜電除塵器廠家

靜電除塵器的工作(zuo)原理(li)是利用(yong)高壓電(dian)(dian)場使煙氣(qi)發生電(dian)(dian)離(li)，氣(qi)流(liu)中(zhong)的粉塵荷電(dian)(dian)在電(dian)(dian)場作(zuo)用(yong)下與氣(qi)流(liu)分離(li)。負極由不同斷(duan)面形狀的金屬導線制成(cheng)，叫(jiao)放電(dian)(dian)電(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)性能受粉塵(chen)(chen)(chen)性質(zhi)、設備構造和(he)煙氣(qi)流速等三(san)個因素的(de)影響(xiang)。粉塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)阻(zu)(zu)是評價導(dao)電(dian)(dian)(dian)(dian)性的(de)指標，它對除塵(chen)(chen)(chen)效(xiao)率有直接(jie)的(de)影響(xiang)。比電(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)(chen)粒難(nan)以保(bao)持在集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)上，致使其重返氣(qi)流。比電(dian)(dian)(dian)(dian)阻(zu)(zu)過高(gao)，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)層之間形成電(dian)(dian)(dian)(dian)壓梯度會(hui)產生局部擊穿(chuan)和(he)放(fang)電(dian)(dian)(dian)(dian)現象。這些情況都會(hui)造成除塵(chen)(chen)(chen)效(xiao)率下(xia)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(xing)電壓(ya)需(xu)保(bao)持(chi)40一75kV乃至(zhi)100kV以上。

工作原理

電除塵(chen)器的(de)基本原理(li)(li)是利用電力捕(bu)集煙氣中的(de)粉塵(chen)，主要包括(kuo)以(yi)下四個相互有關的(de)物(wu)理(li)(li)過程：（1）氣體的(de)電離。（2）粉塵(chen)的(de)荷(he)電。（3）荷(he)電粉塵(chen)向電極移動(dong)。（4）荷(he)電粉塵(chen)的(de)捕(bu)集。

荷電(dian)(dian)粉塵的(de)(de)捕集過程：在(zai)兩個曲率半徑相差(cha)較大(da)的(de)(de)金(jin)屬陽極(ji)和陰極(ji)上，通過高(gao)壓直流電(dian)(dian)，維持一個足以使氣(qi)(qi)體(ti)電(dian)(dian)離(li)(li)的(de)(de)電(dian)(dian)場(chang)，氣(qi)(qi)體(ti)電(dian)(dian)離(li)(li)后所產生的(de)(de)電(dian)(dian)子：陰離(li)(li)子和陽離(li)(li)子，吸附在(zai)通過電(dian)(dian)場(chang)的(de)(de)粉塵上，使粉塵獲(huo)得電(dian)(dian)荷。荷電(dian)(dian)極(ji)性(xing)不同(tong)的(de)(de)粉塵在(zai)電(dian)(dian)場(chang)力的(de)(de)作用下(xia)，分別向不同(tong)極(ji)性(xing)的(de)(de)電(dian)(dian)極(ji)運動，沉積在(zai)電(dian)(dian)極(ji)上，而達到粉塵和氣(qi)(qi)體(ti)分離(li)(li)的(de)(de)目的(de)(de)。

基本結構

靜電(dian)(dian)(dian)電(dian)(dian)(dian)除(chu)塵(chen)器由兩大部分(fen)組(zu)成：一部分(fen)是電(dian)(dian)(dian)除(chu)塵(chen)器本(ben)體系統(tong)；另一部分(fen)是提供(gong)(gong)(gong)高壓(ya)直流電(dian)(dian)(dian)的(de)(de)供(gong)(gong)(gong)電(dian)(dian)(dian)裝(zhuang)置和低(di)壓(ya)自動控(kong)制系統(tong)。電(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)結構(gou)原(yuan)理圖如(ru)圖1所示，高壓(ya)供(gong)(gong)(gong)電(dian)(dian)(dian)系統(tong)為升壓(ya)變(bian)壓(ya)器供(gong)(gong)(gong)電(dian)(dian)(dian)，除(chu)塵(chen)器集塵(chen)極接地。低(di)壓(ya)電(dian)(dian)(dian)控(kong)制系統(tong)用(yong)來控(kong)制電(dian)(dian)(dian)磁(ci)振(zhen)打錘(chui)、卸(xie)灰電(dian)(dian)(dian)極、輸灰電(dian)(dian)(dian)極以及(ji)幾個部件的(de)(de)溫度。
