鞍山靜電除塵器廠家

靜電除塵器的工作(zuo)原(yuan)理是利用(yong)(yong)高壓(ya)電場(chang)使煙氣(qi)(qi)(qi)發生電離，氣(qi)(qi)(qi)流中的粉塵荷電在(zai)電場(chang)作(zuo)用(yong)(yong)下與氣(qi)(qi)(qi)流分離。負極(ji)由不同斷(duan)面形(xing)狀的金屬(shu)導線制成，叫放電電極(ji)。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的性能受粉塵(chen)(chen)(chen)性質、設備構造和(he)煙(yan)氣(qi)流(liu)速等三個因素的影(ying)(ying)響(xiang)。粉塵(chen)(chen)(chen)的比電(dian)(dian)阻(zu)是評(ping)價導電(dian)(dian)性的指標，它(ta)對(dui)除塵(chen)(chen)(chen)效(xiao)率有直接的影(ying)(ying)響(xiang)。比電(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)粒難(nan)以保持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)極上，致使(shi)其重(zhong)返氣(qi)流(liu)。比電(dian)(dian)阻(zu)過高，到達(da)集(ji)塵(chen)(chen)(chen)電(dian)(dian)極的塵(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)(chen)層之(zhi)間形成(cheng)電(dian)(dian)壓(ya)梯度會(hui)產生局部擊穿和(he)放電(dian)(dian)現象。這些情況(kuang)都會(hui)造成(cheng)除塵(chen)(chen)(chen)效(xiao)率下(xia)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，靜電除塵器運行電壓需(xu)保持40一75kV乃至100kV以上。

工作原理

電(dian)(dian)除(chu)塵(chen)器的基本原理是利用電(dian)(dian)力捕集(ji)煙氣中(zhong)的粉(fen)塵(chen)，主要包括(kuo)以下四(si)個相互(hu)有(you)關(guan)的物理過程：（1）氣體的電(dian)(dian)離(li)。（2）粉(fen)塵(chen)的荷(he)電(dian)(dian)。（3）荷(he)電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動。（4）荷(he)電(dian)(dian)粉(fen)塵(chen)的捕集(ji)。

荷電(dian)(dian)(dian)粉塵的(de)(de)捕集過程：在兩個曲率半徑(jing)相差較大的(de)(de)金屬陽極(ji)(ji)和(he)(he)陰極(ji)(ji)上(shang)，通過高(gao)壓直流電(dian)(dian)(dian)，維持一(yi)個足以使氣體電(dian)(dian)(dian)離(li)(li)的(de)(de)電(dian)(dian)(dian)場(chang)，氣體電(dian)(dian)(dian)離(li)(li)后所產生的(de)(de)電(dian)(dian)(dian)子：陰離(li)(li)子和(he)(he)陽離(li)(li)子，吸(xi)附在通過電(dian)(dian)(dian)場(chang)的(de)(de)粉塵上(shang)，使粉塵獲得(de)電(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)極(ji)(ji)性不(bu)同的(de)(de)粉塵在電(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用下，分(fen)別向不(bu)同極(ji)(ji)性的(de)(de)電(dian)(dian)(dian)極(ji)(ji)運動，沉(chen)積在電(dian)(dian)(dian)極(ji)(ji)上(shang)，而(er)達到粉塵和(he)(he)氣體分(fen)離(li)(li)的(de)(de)目的(de)(de)。

基本結構

靜電(dian)(dian)(dian)電(dian)(dian)(dian)除塵器(qi)(qi)由兩大部分(fen)組成(cheng)：一(yi)(yi)部分(fen)是(shi)電(dian)(dian)(dian)除塵器(qi)(qi)本(ben)體系統；另一(yi)(yi)部分(fen)是(shi)提供高(gao)壓(ya)直流(liu)電(dian)(dian)(dian)的(de)供電(dian)(dian)(dian)裝置和(he)低壓(ya)自動控(kong)制(zhi)系統。電(dian)(dian)(dian)除塵器(qi)(qi)的(de)結構原理圖(tu)如圖(tu)1所示，高(gao)壓(ya)供電(dian)(dian)(dian)系統為升(sheng)壓(ya)變壓(ya)器(qi)(qi)供電(dian)(dian)(dian)，除塵器(qi)(qi)集塵極(ji)接地。低壓(ya)電(dian)(dian)(dian)控(kong)制(zhi)系統用來控(kong)制(zhi)電(dian)(dian)(dian)磁振(zhen)打錘(chui)、卸灰電(dian)(dian)(dian)極(ji)、輸(shu)灰電(dian)(dian)(dian)極(ji)以及(ji)幾個部件的(de)溫度。
