臨滄靜電除塵器廠家

靜電除塵器的工(gong)作原理是利用(yong)高壓(ya)電(dian)(dian)場(chang)使煙氣(qi)發(fa)生電(dian)(dian)離(li)(li)，氣(qi)流(liu)中的粉塵荷電(dian)(dian)在電(dian)(dian)場(chang)作用(yong)下與氣(qi)流(liu)分離(li)(li)。負極由不同斷(duan)面(mian)形(xing)狀的金屬導(dao)線制成(cheng)，叫放電(dian)(dian)電(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)性能受粉(fen)塵(chen)(chen)(chen)性質、設備構造和煙(yan)氣流(liu)(liu)速等三個因素的(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)比電(dian)阻是(shi)評價導電(dian)性的(de)指(zhi)標(biao)，它對除(chu)塵(chen)(chen)(chen)效率有直接的(de)影響。比電(dian)阻過(guo)低(di)，塵(chen)(chen)(chen)粒難(nan)以保持(chi)在集塵(chen)(chen)(chen)電(dian)極(ji)上(shang)，致使(shi)其(qi)重返氣流(liu)(liu)。比電(dian)阻過(guo)高，到達集塵(chen)(chen)(chen)電(dian)極(ji)的(de)塵(chen)(chen)(chen)粒電(dian)荷(he)不易放(fang)出，在塵(chen)(chen)(chen)層(ceng)之間形(xing)成(cheng)電(dian)壓(ya)梯度會(hui)產生局(ju)部擊(ji)穿和放(fang)電(dian)現象。這(zhe)些(xie)情況都會(hui)造成(cheng)除(chu)塵(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)電壓需(xu)保(bao)持40一75kV乃至100kV以(yi)上。

工作原理

電除塵(chen)器的(de)基(ji)本(ben)原理是利(li)用電力捕集煙氣(qi)中的(de)粉(fen)塵(chen)，主要(yao)包括以下四個相互(hu)有關的(de)物理過程：（1）氣(qi)體的(de)電離。（2）粉(fen)塵(chen)的(de)荷(he)電。（3）荷(he)電粉(fen)塵(chen)向電極(ji)移動。（4）荷(he)電粉(fen)塵(chen)的(de)捕集。

荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)的(de)(de)(de)捕集(ji)過(guo)(guo)程：在兩個(ge)曲率(lv)半徑相(xiang)差較大的(de)(de)(de)金屬陽極(ji)和陰(yin)(yin)極(ji)上，通過(guo)(guo)高壓(ya)直(zhi)流電(dian)(dian)(dian)，維持一個(ge)足以使氣體電(dian)(dian)(dian)離的(de)(de)(de)電(dian)(dian)(dian)場(chang)，氣體電(dian)(dian)(dian)離后所產生的(de)(de)(de)電(dian)(dian)(dian)子：陰(yin)(yin)離子和陽離子，吸(xi)附(fu)在通過(guo)(guo)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(he)。荷(he)電(dian)(dian)(dian)極(ji)性不(bu)同(tong)(tong)的(de)(de)(de)粉(fen)塵(chen)在電(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用(yong)下，分別向不(bu)同(tong)(tong)極(ji)性的(de)(de)(de)電(dian)(dian)(dian)極(ji)運動，沉積在電(dian)(dian)(dian)極(ji)上，而達到(dao)粉(fen)塵(chen)和氣體分離的(de)(de)(de)目的(de)(de)(de)。

基本結構

靜電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)由兩大部(bu)分(fen)組(zu)成：一部(bu)分(fen)是電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)本體系(xi)(xi)(xi)統；另一部(bu)分(fen)是提供高壓(ya)直流電(dian)(dian)(dian)(dian)的供電(dian)(dian)(dian)(dian)裝(zhuang)置和低(di)壓(ya)自動控(kong)制系(xi)(xi)(xi)統。電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)的結構原(yuan)理圖如圖1所示，高壓(ya)供電(dian)(dian)(dian)(dian)系(xi)(xi)(xi)統為升壓(ya)變壓(ya)器(qi)(qi)供電(dian)(dian)(dian)(dian)，除(chu)塵(chen)器(qi)(qi)集塵(chen)極接地。低(di)壓(ya)電(dian)(dian)(dian)(dian)控(kong)制系(xi)(xi)(xi)統用來控(kong)制電(dian)(dian)(dian)(dian)磁振打錘、卸灰電(dian)(dian)(dian)(dian)極、輸灰電(dian)(dian)(dian)(dian)極以及(ji)幾個部(bu)件(jian)的溫度。
