恩施靜電除塵器廠家

靜電除塵器的工(gong)作(zuo)原理是利用高壓電場使(shi)煙氣(qi)(qi)發生電離(li)，氣(qi)(qi)流中的粉塵(chen)荷電在電場作(zuo)用下與氣(qi)(qi)流分離(li)。負(fu)極由不同斷面形狀(zhuang)的金屬導線制(zhi)成，叫放電電極。

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(xing)能受粉塵(chen)(chen)性(xing)質、設備構造和(he)煙氣流速(su)等三個(ge)因素(su)的影(ying)響。粉塵(chen)(chen)的比電(dian)(dian)阻(zu)是評(ping)價導(dao)電(dian)(dian)性(xing)的指標，它對除塵(chen)(chen)效(xiao)率有(you)直接(jie)的影(ying)響。比電(dian)(dian)阻(zu)過低，塵(chen)(chen)粒難以保持(chi)在(zai)集塵(chen)(chen)電(dian)(dian)極上，致使(shi)其(qi)重返氣流。比電(dian)(dian)阻(zu)過高，到(dao)達集塵(chen)(chen)電(dian)(dian)極的塵(chen)(chen)粒電(dian)(dian)荷不易(yi)放出(chu)，在(zai)塵(chen)(chen)層之間形(xing)成電(dian)(dian)壓梯(ti)度會產生局部擊穿和(he)放電(dian)(dian)現象。這些情(qing)況都會造成除塵(chen)(chen)效(xiao)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需保持(chi)40一75kV乃至100kV以上(shang)。

工作原理

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

荷電(dian)(dian)(dian)粉塵(chen)(chen)的捕集過(guo)程：在(zai)兩個曲(qu)率(lv)半(ban)徑相(xiang)差較大的金屬陽極(ji)和陰極(ji)上，通過(guo)高壓直流電(dian)(dian)(dian)，維持一個足以使(shi)氣體(ti)(ti)電(dian)(dian)(dian)離(li)的電(dian)(dian)(dian)場(chang)，氣體(ti)(ti)電(dian)(dian)(dian)離(li)后所(suo)產生的電(dian)(dian)(dian)子(zi)：陰離(li)子(zi)和陽離(li)子(zi)，吸附在(zai)通過(guo)電(dian)(dian)(dian)場(chang)的粉塵(chen)(chen)上，使(shi)粉塵(chen)(chen)獲得電(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)極(ji)性(xing)不(bu)同的粉塵(chen)(chen)在(zai)電(dian)(dian)(dian)場(chang)力(li)的作用(yong)下，分(fen)(fen)別(bie)向不(bu)同極(ji)性(xing)的電(dian)(dian)(dian)極(ji)運(yun)動，沉積在(zai)電(dian)(dian)(dian)極(ji)上，而達到粉塵(chen)(chen)和氣體(ti)(ti)分(fen)(fen)離(li)的目的。

基本結構

靜電(dian)(dian)電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)由兩大部(bu)(bu)分(fen)(fen)組成：一部(bu)(bu)分(fen)(fen)是電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)本體(ti)系(xi)統(tong)；另(ling)一部(bu)(bu)分(fen)(fen)是提供(gong)高(gao)壓(ya)(ya)直流電(dian)(dian)的(de)供(gong)電(dian)(dian)裝置(zhi)和(he)低壓(ya)(ya)自動控(kong)(kong)制(zhi)(zhi)系(xi)統(tong)。電(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)結構原理(li)圖如圖1所示，高(gao)壓(ya)(ya)供(gong)電(dian)(dian)系(xi)統(tong)為升壓(ya)(ya)變壓(ya)(ya)器(qi)供(gong)電(dian)(dian)，除(chu)塵(chen)(chen)(chen)器(qi)集塵(chen)(chen)(chen)極接地。低壓(ya)(ya)電(dian)(dian)控(kong)(kong)制(zhi)(zhi)系(xi)統(tong)用來控(kong)(kong)制(zhi)(zhi)電(dian)(dian)磁振打錘、卸灰電(dian)(dian)極、輸灰電(dian)(dian)極以及幾個部(bu)(bu)件的(de)溫度。
