南平靜電除塵器廠家

靜電除塵器的(de)工作原理是利(li)用高壓電(dian)場使(shi)煙氣發生(sheng)電(dian)離(li)(li)，氣流中的(de)粉塵荷電(dian)在電(dian)場作用下與氣流分離(li)(li)。負極由不同斷面形狀(zhuang)的(de)金屬導線(xian)制成，叫(jiao)放電(dian)電(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(xing)能受粉(fen)塵(chen)性(xing)質、設備構(gou)造(zao)和煙氣(qi)(qi)流速等三(san)個因素的(de)影響。粉(fen)塵(chen)的(de)比電(dian)(dian)(dian)阻(zu)是(shi)評價(jia)導電(dian)(dian)(dian)性(xing)的(de)指標，它對除塵(chen)效率有直(zhi)接的(de)影響。比電(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)粒難(nan)以保持在集(ji)塵(chen)電(dian)(dian)(dian)極上(shang)，致使其重返氣(qi)(qi)流。比電(dian)(dian)(dian)阻(zu)過(guo)高，到達(da)集(ji)塵(chen)電(dian)(dian)(dian)極的(de)塵(chen)粒電(dian)(dian)(dian)荷不(bu)易放(fang)(fang)出，在塵(chen)層之間形成電(dian)(dian)(dian)壓梯度會產生局(ju)部(bu)擊穿和放(fang)(fang)電(dian)(dian)(dian)現象。這些情(qing)況都會造(zao)成除塵(chen)效率下(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(ya)需保持(chi)40一(yi)75kV乃至100kV以上。

工作原理

電(dian)(dian)(dian)除(chu)塵器(qi)的(de)基本原理是利用電(dian)(dian)(dian)力捕集煙(yan)氣中的(de)粉(fen)塵，主要(yao)包括以下(xia)四個相(xiang)互有(you)關的(de)物理過程：（1）氣體的(de)電(dian)(dian)(dian)離。（2）粉(fen)塵的(de)荷(he)電(dian)(dian)(dian)。（3）荷(he)電(dian)(dian)(dian)粉(fen)塵向電(dian)(dian)(dian)極移動。（4）荷(he)電(dian)(dian)(dian)粉(fen)塵的(de)捕集。

荷(he)(he)電(dian)(dian)粉(fen)塵(chen)(chen)的(de)(de)捕(bu)集過(guo)程(cheng)：在兩個曲(qu)率半(ban)徑相差較大的(de)(de)金屬(shu)陽極和陰極上(shang)，通過(guo)高(gao)壓直流電(dian)(dian)，維(wei)持一(yi)個足以使氣體(ti)電(dian)(dian)離的(de)(de)電(dian)(dian)場(chang)，氣體(ti)電(dian)(dian)離后所產(chan)生的(de)(de)電(dian)(dian)子(zi)：陰離子(zi)和陽離子(zi)，吸附在通過(guo)電(dian)(dian)場(chang)的(de)(de)粉(fen)塵(chen)(chen)上(shang)，使粉(fen)塵(chen)(chen)獲得(de)電(dian)(dian)荷(he)(he)。荷(he)(he)電(dian)(dian)極性不同(tong)的(de)(de)粉(fen)塵(chen)(chen)在電(dian)(dian)場(chang)力的(de)(de)作用下，分別向(xiang)不同(tong)極性的(de)(de)電(dian)(dian)極運(yun)動(dong)，沉積(ji)在電(dian)(dian)極上(shang)，而達到粉(fen)塵(chen)(chen)和氣體(ti)分離的(de)(de)目的(de)(de)。

基本結構

靜(jing)電(dian)(dian)(dian)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)由兩大(da)部(bu)分(fen)組成：一部(bu)分(fen)是電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)本體系(xi)統(tong)；另一部(bu)分(fen)是提供高(gao)壓(ya)直流電(dian)(dian)(dian)的(de)供電(dian)(dian)(dian)裝置和低壓(ya)自(zi)動控(kong)制(zhi)系(xi)統(tong)。電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)結構原(yuan)理(li)圖如圖1所(suo)示(shi)，高(gao)壓(ya)供電(dian)(dian)(dian)系(xi)統(tong)為升壓(ya)變(bian)壓(ya)器(qi)供電(dian)(dian)(dian)，除(chu)塵(chen)(chen)器(qi)集塵(chen)(chen)極接地。低壓(ya)電(dian)(dian)(dian)控(kong)制(zhi)系(xi)統(tong)用來(lai)控(kong)制(zhi)電(dian)(dian)(dian)磁振打(da)錘、卸灰(hui)電(dian)(dian)(dian)極、輸灰(hui)電(dian)(dian)(dian)極以及(ji)幾個部(bu)件的(de)溫度。
