長治靜電除塵器廠家

靜電除塵器的工作(zuo)原理是利用高壓電(dian)場使煙氣發生電(dian)離，氣流中的粉塵荷電(dian)在電(dian)場作(zuo)用下(xia)與氣流分(fen)離。負極由不同斷面形(xing)狀的金屬導線制(zhi)成，叫放電(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)能受粉塵(chen)(chen)(chen)性(xing)質、設備構(gou)造和(he)煙氣(qi)流(liu)速等三個因素的(de)影響(xiang)(xiang)。粉塵(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)阻是評價導電(dian)(dian)性(xing)的(de)指標，它對除塵(chen)(chen)(chen)效率(lv)有直接的(de)影響(xiang)(xiang)。比(bi)電(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒難以保持(chi)在集塵(chen)(chen)(chen)電(dian)(dian)極(ji)上(shang)，致使其重返氣(qi)流(liu)。比(bi)電(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷(he)不(bu)易放(fang)出，在塵(chen)(chen)(chen)層之(zhi)間形成電(dian)(dian)壓(ya)梯度會產生局部擊穿(chuan)和(he)放(fang)電(dian)(dian)現象。這些情(qing)況都會造成除塵(chen)(chen)(chen)效率(lv)下(xia)降(jiang)。

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40一75kV乃至(zhi)100kV以(yi)上(shang)。

工作原理

電(dian)(dian)(dian)除塵(chen)器的基本原理是利用電(dian)(dian)(dian)力捕集(ji)煙氣(qi)(qi)中的粉塵(chen)，主要包括以下四(si)個相互(hu)有關的物理過程：（1）氣(qi)(qi)體的電(dian)(dian)(dian)離。（2）粉塵(chen)的荷電(dian)(dian)(dian)。（3）荷電(dian)(dian)(dian)粉塵(chen)向電(dian)(dian)(dian)極移動。（4）荷電(dian)(dian)(dian)粉塵(chen)的捕集(ji)。

荷電(dian)(dian)粉(fen)塵的(de)(de)(de)捕集過程：在(zai)兩(liang)個曲(qu)率半徑相差較大的(de)(de)(de)金屬陽極(ji)和陰極(ji)上，通過高壓直(zhi)流(liu)電(dian)(dian)，維持(chi)一(yi)個足以使(shi)氣體(ti)電(dian)(dian)離的(de)(de)(de)電(dian)(dian)場，氣體(ti)電(dian)(dian)離后所(suo)產生(sheng)的(de)(de)(de)電(dian)(dian)子：陰離子和陽離子，吸附在(zai)通過電(dian)(dian)場的(de)(de)(de)粉(fen)塵上，使(shi)粉(fen)塵獲(huo)得(de)電(dian)(dian)荷。荷電(dian)(dian)極(ji)性不同(tong)(tong)的(de)(de)(de)粉(fen)塵在(zai)電(dian)(dian)場力的(de)(de)(de)作用下，分(fen)別向(xiang)不同(tong)(tong)極(ji)性的(de)(de)(de)電(dian)(dian)極(ji)運動，沉(chen)積在(zai)電(dian)(dian)極(ji)上，而達到粉(fen)塵和氣體(ti)分(fen)離的(de)(de)(de)目(mu)的(de)(de)(de)。

基本結構

靜電(dian)(dian)電(dian)(dian)除(chu)(chu)塵(chen)(chen)器由兩大部(bu)(bu)分組成：一部(bu)(bu)分是電(dian)(dian)除(chu)(chu)塵(chen)(chen)器本體(ti)系(xi)統(tong)(tong)；另一部(bu)(bu)分是提(ti)供(gong)高壓(ya)直流電(dian)(dian)的供(gong)電(dian)(dian)裝置和低(di)(di)壓(ya)自(zi)動(dong)控制系(xi)統(tong)(tong)。電(dian)(dian)除(chu)(chu)塵(chen)(chen)器的結(jie)構原理(li)圖(tu)如(ru)圖(tu)1所示(shi)，高壓(ya)供(gong)電(dian)(dian)系(xi)統(tong)(tong)為升壓(ya)變(bian)壓(ya)器供(gong)電(dian)(dian)，除(chu)(chu)塵(chen)(chen)器集(ji)塵(chen)(chen)極(ji)接(jie)地(di)。低(di)(di)壓(ya)電(dian)(dian)控制系(xi)統(tong)(tong)用來控制電(dian)(dian)磁振打錘、卸灰(hui)電(dian)(dian)極(ji)、輸灰(hui)電(dian)(dian)極(ji)以及幾(ji)個部(bu)(bu)件的溫度(du)。
