石家莊靜電除塵器廠家

靜電除塵器的工作原理是利用高(gao)壓(ya)電(dian)場(chang)使煙氣(qi)發生電(dian)離，氣(qi)流(liu)中(zhong)的粉塵荷電(dian)在(zai)電(dian)場(chang)作用下與(yu)氣(qi)流(liu)分離。負極由不同斷面形狀的金屬(shu)導線制(zhi)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。靜電除塵器廠家的性能(neng)受粉(fen)塵(chen)(chen)(chen)(chen)性質、設備(bei)構(gou)造(zao)和(he)煙氣(qi)流速等三個因素的影(ying)響(xiang)。粉(fen)塵(chen)(chen)(chen)(chen)的比電(dian)阻(zu)是評價導電(dian)性的指標，它對除(chu)塵(chen)(chen)(chen)(chen)效率(lv)(lv)有直接的影(ying)響(xiang)。比電(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)粒難以(yi)保(bao)持在集塵(chen)(chen)(chen)(chen)電(dian)極(ji)上，致使其重返氣(qi)流。比電(dian)阻(zu)過高(gao)，到達(da)集塵(chen)(chen)(chen)(chen)電(dian)極(ji)的塵(chen)(chen)(chen)(chen)粒電(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)(chen)層之間形(xing)成電(dian)壓(ya)梯度會產(chan)生局部擊穿(chuan)和(he)放(fang)電(dian)現象。這些(xie)情況都會造(zao)成除(chu)塵(chen)(chen)(chen)(chen)效率(lv)(lv)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需保持(chi)40一75kV乃至100kV以上。

工作原理

電(dian)除(chu)塵(chen)器的基本原(yuan)理是利用電(dian)力捕集煙氣(qi)中的粉塵(chen)，主要包括以下四(si)個相互有關(guan)的物理過(guo)程：（1）氣(qi)體的電(dian)離(li)。（2）粉塵(chen)的荷(he)電(dian)。（3）荷(he)電(dian)粉塵(chen)向電(dian)極移動(dong)。（4）荷(he)電(dian)粉塵(chen)的捕集。

荷電(dian)(dian)粉(fen)塵的(de)(de)捕集過(guo)(guo)程：在(zai)兩個曲率半徑相差較大的(de)(de)金屬陽極(ji)和陰極(ji)上，通過(guo)(guo)高壓(ya)直流(liu)電(dian)(dian)，維持(chi)一個足(zu)以使氣體電(dian)(dian)離的(de)(de)電(dian)(dian)場，氣體電(dian)(dian)離后所產生的(de)(de)電(dian)(dian)子(zi)：陰離子(zi)和陽離子(zi)，吸附在(zai)通過(guo)(guo)電(dian)(dian)場的(de)(de)粉(fen)塵上，使粉(fen)塵獲(huo)得電(dian)(dian)荷。荷電(dian)(dian)極(ji)性不同(tong)的(de)(de)粉(fen)塵在(zai)電(dian)(dian)場力的(de)(de)作(zuo)用下，分別向不同(tong)極(ji)性的(de)(de)電(dian)(dian)極(ji)運(yun)動，沉(chen)積在(zai)電(dian)(dian)極(ji)上，而達到粉(fen)塵和氣體分離的(de)(de)目的(de)(de)。

基本結構

靜(jing)電(dian)(dian)(dian)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器由兩(liang)大部(bu)分組成：一部(bu)分是電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器本(ben)體系統(tong)(tong)；另一部(bu)分是提(ti)供(gong)高(gao)壓(ya)(ya)直流電(dian)(dian)(dian)的(de)供(gong)電(dian)(dian)(dian)裝置(zhi)和低(di)(di)壓(ya)(ya)自動控制系統(tong)(tong)。電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器的(de)結構原理圖如圖1所示，高(gao)壓(ya)(ya)供(gong)電(dian)(dian)(dian)系統(tong)(tong)為(wei)升壓(ya)(ya)變壓(ya)(ya)器供(gong)電(dian)(dian)(dian)，除(chu)塵(chen)(chen)(chen)器集(ji)塵(chen)(chen)(chen)極接(jie)地。低(di)(di)壓(ya)(ya)電(dian)(dian)(dian)控制系統(tong)(tong)用來控制電(dian)(dian)(dian)磁(ci)振打錘、卸灰電(dian)(dian)(dian)極、輸灰電(dian)(dian)(dian)極以及(ji)幾個部(bu)件的(de)溫度。
