梧州靜電除塵器廠家

靜電除塵器的工作原理是利用高(gao)壓電(dian)(dian)場使煙氣發生(sheng)電(dian)(dian)離(li)，氣流中的粉塵荷電(dian)(dian)在電(dian)(dian)場作用下與氣流分離(li)。負極(ji)由(you)不同斷面形狀的金屬導線制成，叫放電(dian)(dian)電(dian)(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)性能受粉(fen)塵(chen)(chen)(chen)性質、設備構造和煙氣流(liu)速等三(san)個因(yin)素的(de)影響(xiang)。粉(fen)塵(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)性的(de)指標(biao)，它對(dui)除塵(chen)(chen)(chen)效率(lv)有直接的(de)影響(xiang)。比(bi)電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上(shang)，致使其(qi)重返氣流(liu)。比(bi)電(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)荷(he)不易(yi)放(fang)出，在塵(chen)(chen)(chen)層之(zhi)間形成電(dian)(dian)(dian)壓梯度會(hui)產(chan)生局部(bu)擊穿和放(fang)電(dian)(dian)(dian)現(xian)象。這些情(qing)況都會(hui)造成除塵(chen)(chen)(chen)效率(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(xing)電壓需保持40一75kV乃至(zhi)100kV以上。

工作原理

電(dian)除(chu)塵(chen)器的(de)(de)(de)基(ji)本原理是利用電(dian)力捕集煙氣(qi)(qi)中的(de)(de)(de)粉(fen)塵(chen)，主要包括(kuo)以下四個(ge)相互有關的(de)(de)(de)物理過(guo)程：（1）氣(qi)(qi)體的(de)(de)(de)電(dian)離。（2）粉(fen)塵(chen)的(de)(de)(de)荷(he)(he)電(dian)。（3）荷(he)(he)電(dian)粉(fen)塵(chen)向電(dian)極移動(dong)。（4）荷(he)(he)電(dian)粉(fen)塵(chen)的(de)(de)(de)捕集。

荷電(dian)(dian)(dian)粉(fen)塵(chen)的(de)(de)(de)捕集過程：在(zai)(zai)兩(liang)個曲(qu)率半徑(jing)相差較大的(de)(de)(de)金屬(shu)陽(yang)極(ji)(ji)和(he)陰(yin)(yin)極(ji)(ji)上，通過高(gao)壓直流電(dian)(dian)(dian)，維(wei)持一個足以(yi)使氣體(ti)電(dian)(dian)(dian)離的(de)(de)(de)電(dian)(dian)(dian)場(chang)，氣體(ti)電(dian)(dian)(dian)離后所產生的(de)(de)(de)電(dian)(dian)(dian)子：陰(yin)(yin)離子和(he)陽(yang)離子，吸(xi)附(fu)在(zai)(zai)通過電(dian)(dian)(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)上，使粉(fen)塵(chen)獲得電(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)極(ji)(ji)性不(bu)同(tong)的(de)(de)(de)粉(fen)塵(chen)在(zai)(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用下，分(fen)別向不(bu)同(tong)極(ji)(ji)性的(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)運動，沉積在(zai)(zai)電(dian)(dian)(dian)極(ji)(ji)上，而(er)達到(dao)粉(fen)塵(chen)和(he)氣體(ti)分(fen)離的(de)(de)(de)目的(de)(de)(de)。

基本結構

靜電(dian)(dian)(dian)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)由兩大部分組成：一部分是(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)本體系(xi)(xi)統(tong)(tong)；另(ling)一部分是(shi)提供(gong)高壓直流電(dian)(dian)(dian)的供(gong)電(dian)(dian)(dian)裝(zhuang)置和(he)低壓自動控(kong)制系(xi)(xi)統(tong)(tong)。電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的結構原理圖如圖1所示，高壓供(gong)電(dian)(dian)(dian)系(xi)(xi)統(tong)(tong)為升壓變壓器(qi)供(gong)電(dian)(dian)(dian)，除(chu)塵(chen)(chen)器(qi)集塵(chen)(chen)極接地(di)。低壓電(dian)(dian)(dian)控(kong)制系(xi)(xi)統(tong)(tong)用來控(kong)制電(dian)(dian)(dian)磁振(zhen)打錘、卸灰電(dian)(dian)(dian)極、輸灰電(dian)(dian)(dian)極以及幾個部件的溫度。
