江西靜電除塵器廠家

靜電除塵器的工作原理是利(li)用高壓電(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發生電(dian)(dian)(dian)(dian)離，氣(qi)流中的粉塵荷電(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)場(chang)作用下(xia)與氣(qi)流分離。負極由不同斷面形狀的金屬(shu)導(dao)線制成，叫放電(dian)(dian)(dian)(dian)電(dian)(dian)(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)(de)性能受粉塵(chen)性質、設備(bei)構造和(he)煙氣(qi)(qi)流速等(deng)三(san)個因素的(de)(de)影(ying)響。粉塵(chen)的(de)(de)比(bi)電(dian)阻是(shi)評價導電(dian)性的(de)(de)指標(biao)，它(ta)對除塵(chen)效率有直接的(de)(de)影(ying)響。比(bi)電(dian)阻過(guo)低，塵(chen)粒難以保持(chi)在集塵(chen)電(dian)極上，致使其重(zhong)返氣(qi)(qi)流。比(bi)電(dian)阻過(guo)高，到達集塵(chen)電(dian)極的(de)(de)塵(chen)粒電(dian)荷不易放(fang)出，在塵(chen)層(ceng)之間形成電(dian)壓梯度會產(chan)生局部(bu)擊穿和(he)放(fang)電(dian)現象。這些情況都(dou)會造成除塵(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(yun)行(xing)電壓需保持40一75kV乃至100kV以上。

工作原理

電(dian)(dian)除塵器的(de)基本(ben)原理(li)是利(li)用電(dian)(dian)力(li)捕集煙氣(qi)中的(de)粉塵，主要包括以下(xia)四(si)個相互有關的(de)物理(li)過程(cheng)：（1）氣(qi)體的(de)電(dian)(dian)離。（2）粉塵的(de)荷(he)電(dian)(dian)。（3）荷(he)電(dian)(dian)粉塵向電(dian)(dian)極移動(dong)。（4）荷(he)電(dian)(dian)粉塵的(de)捕集。

荷電(dian)(dian)(dian)(dian)粉塵(chen)的(de)(de)(de)捕集過程(cheng)：在(zai)兩個(ge)曲(qu)率(lv)半徑相差較大的(de)(de)(de)金屬陽(yang)極(ji)(ji)和陰極(ji)(ji)上(shang)，通過高壓直流(liu)電(dian)(dian)(dian)(dian)，維持一(yi)個(ge)足以使(shi)氣體(ti)電(dian)(dian)(dian)(dian)離(li)的(de)(de)(de)電(dian)(dian)(dian)(dian)場(chang)(chang)，氣體(ti)電(dian)(dian)(dian)(dian)離(li)后所產(chan)生(sheng)的(de)(de)(de)電(dian)(dian)(dian)(dian)子：陰離(li)子和陽(yang)離(li)子，吸附在(zai)通過電(dian)(dian)(dian)(dian)場(chang)(chang)的(de)(de)(de)粉塵(chen)上(shang)，使(shi)粉塵(chen)獲得電(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)極(ji)(ji)性不同(tong)的(de)(de)(de)粉塵(chen)在(zai)電(dian)(dian)(dian)(dian)場(chang)(chang)力的(de)(de)(de)作(zuo)用下(xia)，分(fen)別向不同(tong)極(ji)(ji)性的(de)(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(shang)，而達到粉塵(chen)和氣體(ti)分(fen)離(li)的(de)(de)(de)目的(de)(de)(de)。

基本結構

靜電(dian)(dian)電(dian)(dian)除(chu)塵器(qi)(qi)(qi)由兩大部(bu)分(fen)組成：一部(bu)分(fen)是電(dian)(dian)除(chu)塵器(qi)(qi)(qi)本(ben)體(ti)系統(tong)(tong)；另(ling)一部(bu)分(fen)是提供高壓(ya)直流電(dian)(dian)的供電(dian)(dian)裝置和低(di)壓(ya)自動控(kong)制系統(tong)(tong)。電(dian)(dian)除(chu)塵器(qi)(qi)(qi)的結構原理圖如圖1所示，高壓(ya)供電(dian)(dian)系統(tong)(tong)為升(sheng)壓(ya)變壓(ya)器(qi)(qi)(qi)供電(dian)(dian)，除(chu)塵器(qi)(qi)(qi)集塵極接地(di)。低(di)壓(ya)電(dian)(dian)控(kong)制系統(tong)(tong)用來控(kong)制電(dian)(dian)磁振打(da)錘、卸灰(hui)電(dian)(dian)極、輸灰(hui)電(dian)(dian)極以及幾個部(bu)件(jian)的溫度。
