瓊中黎族苗族自治縣靜電除塵器廠家

靜電除塵器的(de)工作(zuo)原理是利用高壓電(dian)場(chang)使煙氣(qi)(qi)發生電(dian)離(li)，氣(qi)(qi)流(liu)中的(de)粉塵荷電(dian)在電(dian)場(chang)作(zuo)用下(xia)與氣(qi)(qi)流(liu)分離(li)。負(fu)極由不同斷面形狀(zhuang)的(de)金屬導線制成(cheng)，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)(de)性(xing)能受粉(fen)塵(chen)(chen)性(xing)質、設備構造和煙(yan)氣流速等三個因(yin)素的(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)比(bi)(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)是評(ping)價導電(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對除(chu)塵(chen)(chen)效率有直接的(de)(de)影響。比(bi)(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)粒難(nan)以保持在集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)上，致使(shi)其(qi)重返氣流。比(bi)(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)過高，到達集(ji)塵(chen)(chen)電(dian)(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易放出(chu)，在塵(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)壓(ya)梯度(du)會產生局部擊(ji)穿(chuan)和放電(dian)(dian)(dian)(dian)現(xian)象。這些情況都會造成(cheng)除(chu)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(yun)行電壓需保持40一(yi)75kV乃至100kV以上。

工作原理

電(dian)(dian)(dian)除塵(chen)器的基本(ben)原理是利用(yong)電(dian)(dian)(dian)力捕集煙氣(qi)中的粉(fen)塵(chen)，主要包括以(yi)下四個相互(hu)有(you)關的物理過程：（1）氣(qi)體的電(dian)(dian)(dian)離。（2）粉(fen)塵(chen)的荷電(dian)(dian)(dian)。（3）荷電(dian)(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)(dian)極移動。（4）荷電(dian)(dian)(dian)粉(fen)塵(chen)的捕集。

荷電(dian)(dian)粉塵的(de)(de)捕集過程：在兩個曲率半徑(jing)相差較大的(de)(de)金屬(shu)陽(yang)極(ji)和陰極(ji)上(shang)，通過高壓直流電(dian)(dian)，維持一個足(zu)以使氣(qi)體電(dian)(dian)離(li)(li)(li)的(de)(de)電(dian)(dian)場，氣(qi)體電(dian)(dian)離(li)(li)(li)后所產生的(de)(de)電(dian)(dian)子(zi)：陰離(li)(li)(li)子(zi)和陽(yang)離(li)(li)(li)子(zi)，吸附(fu)在通過電(dian)(dian)場的(de)(de)粉塵上(shang)，使粉塵獲得(de)電(dian)(dian)荷。荷電(dian)(dian)極(ji)性不(bu)同的(de)(de)粉塵在電(dian)(dian)場力的(de)(de)作用下，分別向不(bu)同極(ji)性的(de)(de)電(dian)(dian)極(ji)運(yun)動(dong)，沉積在電(dian)(dian)極(ji)上(shang)，而達到粉塵和氣(qi)體分離(li)(li)(li)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)器由兩大部(bu)(bu)分組成(cheng)：一部(bu)(bu)分是(shi)電(dian)(dian)(dian)除(chu)塵(chen)器本體系(xi)統；另(ling)一部(bu)(bu)分是(shi)提供(gong)高壓(ya)直(zhi)流電(dian)(dian)(dian)的供(gong)電(dian)(dian)(dian)裝置(zhi)和低壓(ya)自動(dong)控制(zhi)(zhi)系(xi)統。電(dian)(dian)(dian)除(chu)塵(chen)器的結構(gou)原理(li)圖(tu)如圖(tu)1所示，高壓(ya)供(gong)電(dian)(dian)(dian)系(xi)統為升壓(ya)變壓(ya)器供(gong)電(dian)(dian)(dian)，除(chu)塵(chen)器集塵(chen)極接(jie)地(di)。低壓(ya)電(dian)(dian)(dian)控制(zhi)(zhi)系(xi)統用來(lai)控制(zhi)(zhi)電(dian)(dian)(dian)磁振打錘(chui)、卸灰電(dian)(dian)(dian)極、輸灰電(dian)(dian)(dian)極以及幾個部(bu)(bu)件(jian)的溫度。
