五指山靜電除塵器廠家

靜電除塵器的工作(zuo)原理是利用高壓電(dian)場使(shi)煙氣發生電(dian)離，氣流中的粉(fen)塵荷電(dian)在電(dian)場作(zuo)用下與(yu)氣流分離。負極(ji)(ji)由不同斷面形(xing)狀(zhuang)的金屬導線(xian)制成，叫放電(dian)電(dian)極(ji)(ji)。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的性(xing)能受(shou)粉塵(chen)(chen)(chen)(chen)性(xing)質、設備構(gou)造和(he)煙氣流速等三個(ge)因素的影(ying)響。粉塵(chen)(chen)(chen)(chen)的比(bi)電(dian)阻是(shi)評價導電(dian)性(xing)的指標，它對(dui)除塵(chen)(chen)(chen)(chen)效率有直接(jie)的影(ying)響。比(bi)電(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難(nan)以保持在(zai)集(ji)塵(chen)(chen)(chen)(chen)電(dian)極(ji)上，致使其重返氣流。比(bi)電(dian)阻過高(gao)，到達集(ji)塵(chen)(chen)(chen)(chen)電(dian)極(ji)的塵(chen)(chen)(chen)(chen)粒電(dian)荷不(bu)易(yi)放出，在(zai)塵(chen)(chen)(chen)(chen)層(ceng)之間形(xing)成電(dian)壓梯度會產(chan)生局部擊穿和(he)放電(dian)現(xian)象。這些情況都會造成除塵(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(xing)電(dian)壓需保持40一75kV乃至100kV以上。

工作原理

電(dian)除塵(chen)器的(de)基本原理是利用電(dian)力捕集(ji)煙氣中的(de)粉(fen)塵(chen)，主要包括以(yi)下四個相互有(you)關的(de)物理過程：（1）氣體的(de)電(dian)離。（2）粉(fen)塵(chen)的(de)荷(he)電(dian)。（3）荷(he)電(dian)粉(fen)塵(chen)向(xiang)電(dian)極移動。（4）荷(he)電(dian)粉(fen)塵(chen)的(de)捕集(ji)。

荷電(dian)(dian)(dian)(dian)(dian)粉塵(chen)的(de)(de)捕集過程：在(zai)兩個(ge)曲率半(ban)徑相差較大(da)的(de)(de)金屬(shu)陽極(ji)和陰極(ji)上，通過高壓直(zhi)流電(dian)(dian)(dian)(dian)(dian)，維持一(yi)個(ge)足以使氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離(li)(li)的(de)(de)電(dian)(dian)(dian)(dian)(dian)場，氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離(li)(li)后所產(chan)生(sheng)的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)：陰離(li)(li)子(zi)和陽離(li)(li)子(zi)，吸附(fu)在(zai)通過電(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉塵(chen)上，使粉塵(chen)獲得(de)電(dian)(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)(dian)極(ji)性(xing)不(bu)(bu)同的(de)(de)粉塵(chen)在(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作用下，分別向不(bu)(bu)同極(ji)性(xing)的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)運動(dong)，沉積(ji)在(zai)電(dian)(dian)(dian)(dian)(dian)極(ji)上，而達到(dao)粉塵(chen)和氣(qi)體(ti)分離(li)(li)的(de)(de)目的(de)(de)。

基本結構

靜電(dian)電(dian)除(chu)(chu)(chu)塵器(qi)由兩大部分組成：一部分是電(dian)除(chu)(chu)(chu)塵器(qi)本(ben)體系統；另(ling)一部分是提供(gong)(gong)高壓(ya)直流電(dian)的供(gong)(gong)電(dian)裝置和(he)低(di)壓(ya)自動控(kong)制(zhi)系統。電(dian)除(chu)(chu)(chu)塵器(qi)的結構(gou)原理圖如圖1所(suo)示，高壓(ya)供(gong)(gong)電(dian)系統為升壓(ya)變壓(ya)器(qi)供(gong)(gong)電(dian)，除(chu)(chu)(chu)塵器(qi)集塵極(ji)(ji)接地。低(di)壓(ya)電(dian)控(kong)制(zhi)系統用來控(kong)制(zhi)電(dian)磁振打(da)錘(chui)、卸灰(hui)電(dian)極(ji)(ji)、輸(shu)灰(hui)電(dian)極(ji)(ji)以及幾個部件的溫度(du)。
