惠州靜電除塵器廠家

靜電除塵器的工作原(yuan)理是利用(yong)高壓電(dian)(dian)場使煙(yan)氣(qi)發生電(dian)(dian)離，氣(qi)流中的粉塵荷(he)電(dian)(dian)在電(dian)(dian)場作用(yong)下(xia)與(yu)氣(qi)流分離。負極由不(bu)同(tong)斷面形(xing)狀的金屬導線(xian)制成，叫放電(dian)(dian)電(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(de)(de)性能受(shou)粉(fen)塵(chen)(chen)性質、設備(bei)構造和(he)煙(yan)氣(qi)(qi)流速等(deng)三個(ge)因素的(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)比電(dian)阻(zu)是評(ping)價導電(dian)性的(de)(de)指標，它對除塵(chen)(chen)效率有直(zhi)接的(de)(de)影響。比電(dian)阻(zu)過低，塵(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)電(dian)極上，致使其(qi)重返(fan)氣(qi)(qi)流。比電(dian)阻(zu)過高，到達集(ji)塵(chen)(chen)電(dian)極的(de)(de)塵(chen)(chen)粒電(dian)荷(he)不易放出，在塵(chen)(chen)層之(zhi)間形成電(dian)壓(ya)梯度會(hui)產生(sheng)局(ju)部擊(ji)穿和(he)放電(dian)現象。這些(xie)情況都會(hui)造成除塵(chen)(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(yun)行電壓需(xu)保持40一75kV乃至100kV以上。

工作原理

電(dian)(dian)(dian)除塵(chen)(chen)器的基本原理是利用電(dian)(dian)(dian)力捕(bu)集(ji)煙氣中(zhong)的粉塵(chen)(chen)，主(zhu)要包括以下四個相互有關(guan)的物理過程：（1）氣體的電(dian)(dian)(dian)離(li)。（2）粉塵(chen)(chen)的荷(he)電(dian)(dian)(dian)。（3）荷(he)電(dian)(dian)(dian)粉塵(chen)(chen)向電(dian)(dian)(dian)極移(yi)動。（4）荷(he)電(dian)(dian)(dian)粉塵(chen)(chen)的捕(bu)集(ji)。

荷電(dian)(dian)(dian)粉(fen)塵(chen)(chen)(chen)的捕集過(guo)程(cheng)：在兩個曲(qu)率(lv)半(ban)徑相差較大的金屬陽極(ji)(ji)和陰極(ji)(ji)上(shang)，通過(guo)高壓直流電(dian)(dian)(dian)，維(wei)持一(yi)個足以使氣(qi)體電(dian)(dian)(dian)離(li)(li)的電(dian)(dian)(dian)場(chang)，氣(qi)體電(dian)(dian)(dian)離(li)(li)后(hou)所(suo)產生的電(dian)(dian)(dian)子(zi)：陰離(li)(li)子(zi)和陽離(li)(li)子(zi)，吸附在通過(guo)電(dian)(dian)(dian)場(chang)的粉(fen)塵(chen)(chen)(chen)上(shang)，使粉(fen)塵(chen)(chen)(chen)獲得電(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)極(ji)(ji)性(xing)不(bu)同(tong)的粉(fen)塵(chen)(chen)(chen)在電(dian)(dian)(dian)場(chang)力的作用(yong)下，分別(bie)向不(bu)同(tong)極(ji)(ji)性(xing)的電(dian)(dian)(dian)極(ji)(ji)運動，沉積在電(dian)(dian)(dian)極(ji)(ji)上(shang)，而達到粉(fen)塵(chen)(chen)(chen)和氣(qi)體分離(li)(li)的目的。

基本結構

靜電(dian)(dian)(dian)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)由兩大部(bu)分組(zu)成：一部(bu)分是(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)本體系(xi)統；另一部(bu)分是(shi)提供高壓(ya)(ya)直流電(dian)(dian)(dian)的(de)供電(dian)(dian)(dian)裝置(zhi)和低壓(ya)(ya)自動控制(zhi)系(xi)統。電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)結構原理圖如圖1所示，高壓(ya)(ya)供電(dian)(dian)(dian)系(xi)統為升壓(ya)(ya)變壓(ya)(ya)器(qi)供電(dian)(dian)(dian)，除(chu)(chu)塵(chen)(chen)器(qi)集塵(chen)(chen)極接地。低壓(ya)(ya)電(dian)(dian)(dian)控制(zhi)系(xi)統用來控制(zhi)電(dian)(dian)(dian)磁(ci)振打錘、卸灰電(dian)(dian)(dian)極、輸灰電(dian)(dian)(dian)極以及幾個(ge)部(bu)件的(de)溫(wen)度。
