廣東靜電除塵器廠家

靜電除塵器的(de)工(gong)作原理是利用高壓電(dian)場使煙(yan)氣發生電(dian)離，氣流中的(de)粉(fen)塵(chen)荷電(dian)在電(dian)場作用下與(yu)氣流分離。負極(ji)由不同斷面(mian)形狀的(de)金屬導線制成(cheng)，叫放電(dian)電(dian)極(ji)。

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(xing)(xing)能受粉塵(chen)(chen)性(xing)(xing)質、設備構造(zao)和(he)煙氣(qi)流速等三(san)個因(yin)素的(de)(de)影(ying)響(xiang)。粉塵(chen)(chen)的(de)(de)比(bi)電(dian)(dian)阻是評價導電(dian)(dian)性(xing)(xing)的(de)(de)指標，它(ta)對除(chu)塵(chen)(chen)效率有直接的(de)(de)影(ying)響(xiang)。比(bi)電(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)粒難以保(bao)持(chi)在集塵(chen)(chen)電(dian)(dian)極上，致(zhi)使其重返氣(qi)流。比(bi)電(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)電(dian)(dian)極的(de)(de)塵(chen)(chen)粒電(dian)(dian)荷不易放出(chu)，在塵(chen)(chen)層之(zhi)間(jian)形成電(dian)(dian)壓梯度會產生局(ju)部擊穿和(he)放電(dian)(dian)現(xian)象。這些情(qing)況都會造(zao)成除(chu)塵(chen)(chen)效率下降(jiang)。

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(yun)行電壓需保持(chi)40一75kV乃至(zhi)100kV以上。

工作原理

電(dian)除塵器的(de)基本原理(li)是利用(yong)電(dian)力捕集煙(yan)氣中的(de)粉(fen)塵，主要包括以下四(si)個相互(hu)有關的(de)物理(li)過程(cheng)：（1）氣體的(de)電(dian)離。（2）粉(fen)塵的(de)荷電(dian)。（3）荷電(dian)粉(fen)塵向電(dian)極移動。（4）荷電(dian)粉(fen)塵的(de)捕集。

荷電(dian)(dian)(dian)(dian)粉塵(chen)(chen)的(de)(de)捕集過(guo)程：在(zai)兩個曲率半徑(jing)相差較大的(de)(de)金屬陽極(ji)(ji)和(he)陰(yin)極(ji)(ji)上，通(tong)過(guo)高壓直(zhi)流電(dian)(dian)(dian)(dian)，維持一個足(zu)以使氣(qi)體電(dian)(dian)(dian)(dian)離的(de)(de)電(dian)(dian)(dian)(dian)場，氣(qi)體電(dian)(dian)(dian)(dian)離后所產生的(de)(de)電(dian)(dian)(dian)(dian)子(zi)：陰(yin)離子(zi)和(he)陽離子(zi)，吸附(fu)在(zai)通(tong)過(guo)電(dian)(dian)(dian)(dian)場的(de)(de)粉塵(chen)(chen)上，使粉塵(chen)(chen)獲(huo)得電(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)極(ji)(ji)性(xing)(xing)不同的(de)(de)粉塵(chen)(chen)在(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)作用下，分別向不同極(ji)(ji)性(xing)(xing)的(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)運動，沉積在(zai)電(dian)(dian)(dian)(dian)極(ji)(ji)上，而達到(dao)粉塵(chen)(chen)和(he)氣(qi)體分離的(de)(de)目的(de)(de)。

基本結構

靜電(dian)(dian)(dian)電(dian)(dian)(dian)除塵(chen)器(qi)由兩大部分(fen)組成：一部分(fen)是電(dian)(dian)(dian)除塵(chen)器(qi)本體系統；另(ling)一部分(fen)是提供高壓(ya)(ya)直流電(dian)(dian)(dian)的(de)供電(dian)(dian)(dian)裝置(zhi)和低壓(ya)(ya)自(zi)動(dong)控制(zhi)系統。電(dian)(dian)(dian)除塵(chen)器(qi)的(de)結構原(yuan)理圖如(ru)圖1所示，高壓(ya)(ya)供電(dian)(dian)(dian)系統為升(sheng)壓(ya)(ya)變壓(ya)(ya)器(qi)供電(dian)(dian)(dian)，除塵(chen)器(qi)集(ji)塵(chen)極接地。低壓(ya)(ya)電(dian)(dian)(dian)控制(zhi)系統用來控制(zhi)電(dian)(dian)(dian)磁振打錘、卸灰電(dian)(dian)(dian)極、輸灰電(dian)(dian)(dian)極以及幾(ji)個部件的(de)溫(wen)度。
