迪慶靜電除塵器廠家

靜電除塵器的(de)(de)工作原理是利用高壓電(dian)(dian)(dian)場使煙氣發(fa)生電(dian)(dian)(dian)離，氣流中(zhong)的(de)(de)粉塵荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用下與氣流分離。負極由不同斷面形狀的(de)(de)金(jin)屬(shu)導線制(zhi)成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的性能受(shou)粉塵(chen)(chen)性質(zhi)、設備構造和(he)煙氣流(liu)速等三個因素的影響。粉塵(chen)(chen)的比(bi)電(dian)(dian)阻(zu)是(shi)評價(jia)導電(dian)(dian)性的指(zhi)標，它對除(chu)塵(chen)(chen)效(xiao)率有直(zhi)接(jie)的影響。比(bi)電(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)粒難以保(bao)持在集塵(chen)(chen)電(dian)(dian)極上，致使其重返氣流(liu)。比(bi)電(dian)(dian)阻(zu)過(guo)高(gao)，到達集塵(chen)(chen)電(dian)(dian)極的塵(chen)(chen)粒電(dian)(dian)荷不易(yi)放出(chu)，在塵(chen)(chen)層之(zhi)間形(xing)成電(dian)(dian)壓梯度(du)會產生局部擊穿(chuan)和(he)放電(dian)(dian)現象。這些(xie)情況都會造成除(chu)塵(chen)(chen)效(xiao)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(ya)需(xu)保持(chi)40一75kV乃(nai)至100kV以上。

工作原理

電(dian)(dian)(dian)除塵器的基(ji)本原理(li)是利用(yong)電(dian)(dian)(dian)力捕集煙氣中(zhong)的粉(fen)塵，主(zhu)要包(bao)括(kuo)以下四個相互有關的物(wu)理(li)過程：（1）氣體的電(dian)(dian)(dian)離。（2）粉(fen)塵的荷電(dian)(dian)(dian)。（3）荷電(dian)(dian)(dian)粉(fen)塵向電(dian)(dian)(dian)極移(yi)動。（4）荷電(dian)(dian)(dian)粉(fen)塵的捕集。

荷電(dian)(dian)粉(fen)塵的捕集過程：在兩個曲率半徑相差(cha)較大的金屬陽(yang)極(ji)和陰(yin)(yin)極(ji)上(shang)(shang)，通過高壓直流電(dian)(dian)，維持一個足以使(shi)氣體(ti)電(dian)(dian)離(li)的電(dian)(dian)場(chang)，氣體(ti)電(dian)(dian)離(li)后所產生的電(dian)(dian)子(zi)：陰(yin)(yin)離(li)子(zi)和陽(yang)離(li)子(zi)，吸附在通過電(dian)(dian)場(chang)的粉(fen)塵上(shang)(shang)，使(shi)粉(fen)塵獲(huo)得(de)電(dian)(dian)荷。荷電(dian)(dian)極(ji)性不同的粉(fen)塵在電(dian)(dian)場(chang)力的作(zuo)用下(xia)，分別向不同極(ji)性的電(dian)(dian)極(ji)運動(dong)，沉積(ji)在電(dian)(dian)極(ji)上(shang)(shang)，而達到粉(fen)塵和氣體(ti)分離(li)的目(mu)的。

基本結構

靜電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)除塵(chen)器由(you)兩大部(bu)分組成：一部(bu)分是電(dian)(dian)(dian)(dian)除塵(chen)器本體(ti)系(xi)統(tong)；另一部(bu)分是提供(gong)高(gao)壓直流(liu)電(dian)(dian)(dian)(dian)的(de)供(gong)電(dian)(dian)(dian)(dian)裝置(zhi)和低壓自動(dong)控制系(xi)統(tong)。電(dian)(dian)(dian)(dian)除塵(chen)器的(de)結(jie)構(gou)原理圖如圖1所示，高(gao)壓供(gong)電(dian)(dian)(dian)(dian)系(xi)統(tong)為升壓變壓器供(gong)電(dian)(dian)(dian)(dian)，除塵(chen)器集塵(chen)極(ji)(ji)接地(di)。低壓電(dian)(dian)(dian)(dian)控制系(xi)統(tong)用來控制電(dian)(dian)(dian)(dian)磁振打錘、卸灰(hui)電(dian)(dian)(dian)(dian)極(ji)(ji)、輸灰(hui)電(dian)(dian)(dian)(dian)極(ji)(ji)以及幾個部(bu)件的(de)溫度。
