錫林郭勒盟靜電除塵器廠家

靜電除塵器的工作原理是利用高(gao)壓電場(chang)使煙氣(qi)(qi)發生電離(li)，氣(qi)(qi)流(liu)中的粉塵荷電在(zai)電場(chang)作用下與氣(qi)(qi)流(liu)分離(li)。負極由不同斷面形狀的金屬導線制成(cheng)，叫放(fang)電電極。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的性(xing)能受(shou)粉塵(chen)(chen)(chen)性(xing)質、設備構造和煙氣流(liu)速(su)等三個因(yin)素的影響。粉塵(chen)(chen)(chen)的比電(dian)(dian)阻是評價導電(dian)(dian)性(xing)的指(zhi)標，它對除(chu)塵(chen)(chen)(chen)效(xiao)率有(you)直接的影響。比電(dian)(dian)阻過低，塵(chen)(chen)(chen)粒(li)難以保持(chi)在(zai)集塵(chen)(chen)(chen)電(dian)(dian)極上，致使其重返氣流(liu)。比電(dian)(dian)阻過高，到(dao)達集塵(chen)(chen)(chen)電(dian)(dian)極的塵(chen)(chen)(chen)粒(li)電(dian)(dian)荷不易放出，在(zai)塵(chen)(chen)(chen)層之(zhi)間形成電(dian)(dian)壓梯度會產生局部擊(ji)穿和放電(dian)(dian)現象(xiang)。這些(xie)情況都會造成除(chu)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保持40一(yi)75kV乃至100kV以上。

工作原理

電(dian)(dian)(dian)除(chu)塵器的(de)基本原理(li)是利用電(dian)(dian)(dian)力捕(bu)集煙(yan)氣中(zhong)的(de)粉(fen)(fen)(fen)塵，主要(yao)包括以下四個相(xiang)互有關(guan)的(de)物理(li)過程：（1）氣體的(de)電(dian)(dian)(dian)離。（2）粉(fen)(fen)(fen)塵的(de)荷(he)電(dian)(dian)(dian)。（3）荷(he)電(dian)(dian)(dian)粉(fen)(fen)(fen)塵向電(dian)(dian)(dian)極移動。（4）荷(he)電(dian)(dian)(dian)粉(fen)(fen)(fen)塵的(de)捕(bu)集。

荷電(dian)(dian)(dian)(dian)粉(fen)(fen)塵的捕集過程(cheng)：在(zai)(zai)兩個(ge)曲率半徑(jing)相(xiang)差較大的金屬陽極(ji)和陰極(ji)上(shang)，通過高壓直流電(dian)(dian)(dian)(dian)，維持一(yi)個(ge)足以使氣(qi)體電(dian)(dian)(dian)(dian)離(li)的電(dian)(dian)(dian)(dian)場，氣(qi)體電(dian)(dian)(dian)(dian)離(li)后所產生(sheng)的電(dian)(dian)(dian)(dian)子：陰離(li)子和陽離(li)子，吸附(fu)在(zai)(zai)通過電(dian)(dian)(dian)(dian)場的粉(fen)(fen)塵上(shang)，使粉(fen)(fen)塵獲(huo)得(de)電(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)極(ji)性(xing)不(bu)同(tong)的粉(fen)(fen)塵在(zai)(zai)電(dian)(dian)(dian)(dian)場力的作(zuo)用下，分(fen)(fen)別向不(bu)同(tong)極(ji)性(xing)的電(dian)(dian)(dian)(dian)極(ji)運動，沉積(ji)在(zai)(zai)電(dian)(dian)(dian)(dian)極(ji)上(shang)，而達到粉(fen)(fen)塵和氣(qi)體分(fen)(fen)離(li)的目的。

基本結構

靜電(dian)(dian)電(dian)(dian)除(chu)塵(chen)器(qi)(qi)由兩大部(bu)(bu)分(fen)(fen)組成(cheng)：一部(bu)(bu)分(fen)(fen)是電(dian)(dian)除(chu)塵(chen)器(qi)(qi)本體系統(tong)；另一部(bu)(bu)分(fen)(fen)是提供高(gao)壓(ya)直流電(dian)(dian)的(de)供電(dian)(dian)裝(zhuang)置和低壓(ya)自(zi)動控制(zhi)(zhi)系統(tong)。電(dian)(dian)除(chu)塵(chen)器(qi)(qi)的(de)結構原理圖如圖1所示，高(gao)壓(ya)供電(dian)(dian)系統(tong)為升(sheng)壓(ya)變壓(ya)器(qi)(qi)供電(dian)(dian)，除(chu)塵(chen)器(qi)(qi)集塵(chen)極接地。低壓(ya)電(dian)(dian)控制(zhi)(zhi)系統(tong)用來控制(zhi)(zhi)電(dian)(dian)磁振打(da)錘、卸灰(hui)電(dian)(dian)極、輸灰(hui)電(dian)(dian)極以及(ji)幾(ji)個部(bu)(bu)件的(de)溫(wen)度。
