南充靜電除塵器廠家

靜電除塵器的(de)工作原理是利用(yong)高(gao)壓電(dian)場使煙氣(qi)發生電(dian)離，氣(qi)流中的(de)粉(fen)塵荷電(dian)在電(dian)場作用(yong)下(xia)與氣(qi)流分離。負極(ji)由(you)不同斷面形狀(zhuang)的(de)金(jin)屬導線制成，叫放電(dian)電(dian)極(ji)。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的性能受粉塵(chen)(chen)(chen)性質、設備(bei)構造和煙氣流速等三個(ge)因素的影(ying)響。粉塵(chen)(chen)(chen)的比(bi)電(dian)(dian)(dian)(dian)(dian)阻是評價導電(dian)(dian)(dian)(dian)(dian)性的指標，它(ta)對除塵(chen)(chen)(chen)效率有直接的影(ying)響。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)(chen)粒(li)難以保持在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致使其重返(fan)氣流。比(bi)電(dian)(dian)(dian)(dian)(dian)阻過高，到(dao)達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)(dian)(dian)荷(he)不易(yi)放出(chu)，在(zai)塵(chen)(chen)(chen)層之(zhi)間形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯度會產(chan)生局部擊(ji)穿和放電(dian)(dian)(dian)(dian)(dian)現象(xiang)。這些情況都會造成(cheng)除塵(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，靜電除塵器運行電壓需保(bao)持40一75kV乃(nai)至100kV以上。

工作原理

電(dian)除(chu)塵(chen)器(qi)的(de)基本原理(li)是利(li)用電(dian)力(li)捕集(ji)煙(yan)氣(qi)中的(de)粉(fen)塵(chen)，主要包括以(yi)下四個相(xiang)互有關的(de)物理(li)過程：（1）氣(qi)體的(de)電(dian)離。（2）粉(fen)塵(chen)的(de)荷電(dian)。（3）荷電(dian)粉(fen)塵(chen)向電(dian)極移動。（4）荷電(dian)粉(fen)塵(chen)的(de)捕集(ji)。

荷電(dian)(dian)(dian)粉(fen)塵(chen)的(de)捕集過程：在(zai)(zai)兩個曲率半徑相差較大的(de)金屬陽極(ji)(ji)和陰(yin)極(ji)(ji)上，通(tong)過高壓直流電(dian)(dian)(dian)，維持(chi)一個足以使氣(qi)體(ti)電(dian)(dian)(dian)離(li)的(de)電(dian)(dian)(dian)場，氣(qi)體(ti)電(dian)(dian)(dian)離(li)后所產生的(de)電(dian)(dian)(dian)子(zi)：陰(yin)離(li)子(zi)和陽離(li)子(zi)，吸附在(zai)(zai)通(tong)過電(dian)(dian)(dian)場的(de)粉(fen)塵(chen)上，使粉(fen)塵(chen)獲得(de)電(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)極(ji)(ji)性不同(tong)(tong)的(de)粉(fen)塵(chen)在(zai)(zai)電(dian)(dian)(dian)場力的(de)作用下，分別(bie)向不同(tong)(tong)極(ji)(ji)性的(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)達到粉(fen)塵(chen)和氣(qi)體(ti)分離(li)的(de)目的(de)。

基本結構

靜電(dian)電(dian)除塵(chen)器(qi)由兩(liang)大(da)部分組成：一部分是電(dian)除塵(chen)器(qi)本體系(xi)統；另一部分是提供(gong)高(gao)壓(ya)(ya)直流電(dian)的供(gong)電(dian)裝置和低(di)壓(ya)(ya)自動控制(zhi)系(xi)統。電(dian)除塵(chen)器(qi)的結構原(yuan)理圖(tu)如(ru)圖(tu)1所示，高(gao)壓(ya)(ya)供(gong)電(dian)系(xi)統為升壓(ya)(ya)變(bian)壓(ya)(ya)器(qi)供(gong)電(dian)，除塵(chen)器(qi)集(ji)塵(chen)極(ji)接地。低(di)壓(ya)(ya)電(dian)控制(zhi)系(xi)統用來控制(zhi)電(dian)磁振打錘、卸灰電(dian)極(ji)、輸灰電(dian)極(ji)以及幾個(ge)部件的溫度。
