太原靜電除塵器廠家

靜電除塵器的工作(zuo)原理是利用(yong)高壓(ya)電場(chang)使煙氣(qi)發生電離，氣(qi)流中(zhong)的粉塵(chen)荷(he)電在電場(chang)作(zuo)用(yong)下與氣(qi)流分離。負極由不(bu)同斷面形狀的金屬導線制成，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(de)性能受粉塵(chen)(chen)性質、設備構造和煙氣(qi)流速等三個因素的(de)影響。粉塵(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)(dian)性的(de)指標，它(ta)對除塵(chen)(chen)效(xiao)率有(you)直接的(de)影響。比電(dian)(dian)(dian)(dian)阻過(guo)低(di)，塵(chen)(chen)粒難以(yi)保持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)極上(shang)，致使其重返氣(qi)流。比電(dian)(dian)(dian)(dian)阻過(guo)高，到(dao)達(da)集塵(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)層之(zhi)間形成電(dian)(dian)(dian)(dian)壓梯(ti)度會產(chan)生局部擊(ji)穿(chuan)和放電(dian)(dian)(dian)(dian)現象。這些(xie)情況都(dou)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(dian)壓需保持40一75kV乃至100kV以上。

工作原理

電(dian)除塵(chen)(chen)(chen)器的基本原理是(shi)利用電(dian)力(li)捕(bu)集煙氣中(zhong)的粉塵(chen)(chen)(chen)，主要包(bao)括以下(xia)四個相互有(you)關(guan)的物理過程：（1）氣體的電(dian)離。（2）粉塵(chen)(chen)(chen)的荷(he)電(dian)。（3）荷(he)電(dian)粉塵(chen)(chen)(chen)向電(dian)極移動。（4）荷(he)電(dian)粉塵(chen)(chen)(chen)的捕(bu)集。

荷(he)電(dian)(dian)(dian)粉(fen)塵的(de)(de)捕集過(guo)程(cheng)：在(zai)兩個曲率(lv)半(ban)徑(jing)相差(cha)較大的(de)(de)金(jin)屬陽(yang)極(ji)和(he)陰(yin)極(ji)上，通過(guo)高壓(ya)直流電(dian)(dian)(dian)，維持一(yi)個足以使(shi)(shi)氣(qi)體(ti)(ti)電(dian)(dian)(dian)離的(de)(de)電(dian)(dian)(dian)場，氣(qi)體(ti)(ti)電(dian)(dian)(dian)離后所產生的(de)(de)電(dian)(dian)(dian)子(zi)：陰(yin)離子(zi)和(he)陽(yang)離子(zi)，吸附(fu)在(zai)通過(guo)電(dian)(dian)(dian)場的(de)(de)粉(fen)塵上，使(shi)(shi)粉(fen)塵獲(huo)得(de)電(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)極(ji)性不同的(de)(de)粉(fen)塵在(zai)電(dian)(dian)(dian)場力的(de)(de)作(zuo)用下，分別向不同極(ji)性的(de)(de)電(dian)(dian)(dian)極(ji)運動，沉(chen)積在(zai)電(dian)(dian)(dian)極(ji)上，而達到粉(fen)塵和(he)氣(qi)體(ti)(ti)分離的(de)(de)目的(de)(de)。

基本結構

靜電(dian)(dian)電(dian)(dian)除塵器(qi)(qi)由兩大部(bu)分組成：一部(bu)分是電(dian)(dian)除塵器(qi)(qi)本體(ti)系(xi)統；另一部(bu)分是提供高壓(ya)直流電(dian)(dian)的供電(dian)(dian)裝置和低(di)壓(ya)自(zi)動控制系(xi)統。電(dian)(dian)除塵器(qi)(qi)的結構原理圖如(ru)圖1所示(shi)，高壓(ya)供電(dian)(dian)系(xi)統為升(sheng)壓(ya)變壓(ya)器(qi)(qi)供電(dian)(dian)，除塵器(qi)(qi)集塵極(ji)(ji)(ji)接地。低(di)壓(ya)電(dian)(dian)控制系(xi)統用來控制電(dian)(dian)磁振打(da)錘、卸灰(hui)電(dian)(dian)極(ji)(ji)(ji)、輸灰(hui)電(dian)(dian)極(ji)(ji)(ji)以及幾(ji)個部(bu)件(jian)的溫度。
