文山靜電除塵器廠家

靜電除塵器的(de)(de)工作(zuo)(zuo)原(yuan)理(li)是利用高壓電場使煙氣(qi)發生電離(li)，氣(qi)流中的(de)(de)粉塵荷電在電場作(zuo)(zuo)用下(xia)與氣(qi)流分離(li)。負極由不同(tong)斷面形狀的(de)(de)金屬導線(xian)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。靜電除塵器廠家的性(xing)能(neng)受(shou)粉塵(chen)(chen)性(xing)質(zhi)、設(she)備(bei)構造(zao)和(he)煙氣流(liu)(liu)速等(deng)三個(ge)因素的影響。粉塵(chen)(chen)的比電(dian)(dian)阻(zu)是評價導電(dian)(dian)性(xing)的指標，它對除塵(chen)(chen)效率有(you)直接的影響。比電(dian)(dian)阻(zu)過(guo)(guo)低，塵(chen)(chen)粒難以保(bao)持在集塵(chen)(chen)電(dian)(dian)極上，致使其重返(fan)氣流(liu)(liu)。比電(dian)(dian)阻(zu)過(guo)(guo)高，到達集塵(chen)(chen)電(dian)(dian)極的塵(chen)(chen)粒電(dian)(dian)荷不易放(fang)(fang)出，在塵(chen)(chen)層之間形成電(dian)(dian)壓梯度(du)會產(chan)生局部擊穿(chuan)和(he)放(fang)(fang)電(dian)(dian)現象。這些情(qing)況都會造(zao)成除塵(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乃至100kV以(yi)上(shang)。

工作原理

電(dian)除塵器的(de)基(ji)本原理是利(li)用電(dian)力捕(bu)集(ji)煙(yan)氣中的(de)粉塵，主要包括以(yi)下四個相互有關的(de)物理過程：（1）氣體的(de)電(dian)離(li)。（2）粉塵的(de)荷(he)(he)電(dian)。（3）荷(he)(he)電(dian)粉塵向(xiang)電(dian)極移動。（4）荷(he)(he)電(dian)粉塵的(de)捕(bu)集(ji)。

荷電(dian)(dian)(dian)(dian)(dian)(dian)粉(fen)塵的(de)(de)捕集過(guo)(guo)(guo)程：在(zai)兩個(ge)曲率半徑相差(cha)較大的(de)(de)金屬陽極(ji)和(he)陰極(ji)上，通(tong)過(guo)(guo)(guo)高壓直流電(dian)(dian)(dian)(dian)(dian)(dian)，維持一個(ge)足以使氣體電(dian)(dian)(dian)(dian)(dian)(dian)離(li)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)，氣體電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后(hou)所產生的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子：陰離(li)子和(he)陽離(li)子，吸附(fu)在(zai)通(tong)過(guo)(guo)(guo)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)塵上，使粉(fen)塵獲得電(dian)(dian)(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)性(xing)不(bu)同(tong)的(de)(de)粉(fen)塵在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用(yong)下，分(fen)別向(xiang)不(bu)同(tong)極(ji)性(xing)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)運動，沉積在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上，而達(da)到粉(fen)塵和(he)氣體分(fen)離(li)的(de)(de)目的(de)(de)。

基本結構

靜電電除塵(chen)(chen)器(qi)由兩大部分(fen)組成：一(yi)部分(fen)是電除塵(chen)(chen)器(qi)本體系(xi)統(tong)(tong)；另一(yi)部分(fen)是提供高壓(ya)直流電的供電裝置(zhi)和(he)低(di)壓(ya)自動控制系(xi)統(tong)(tong)。電除塵(chen)(chen)器(qi)的結構(gou)原理圖如(ru)圖1所示，高壓(ya)供電系(xi)統(tong)(tong)為升壓(ya)變壓(ya)器(qi)供電，除塵(chen)(chen)器(qi)集塵(chen)(chen)極接地。低(di)壓(ya)電控制系(xi)統(tong)(tong)用來控制電磁振打錘、卸(xie)灰(hui)電極、輸灰(hui)電極以及幾個部件(jian)的溫度。
