柳州靜電除塵器廠家

靜電除塵器的(de)工作原理是利用高壓電(dian)(dian)場使煙氣(qi)發生電(dian)(dian)離，氣(qi)流(liu)中的(de)粉塵荷(he)電(dian)(dian)在電(dian)(dian)場作用下與氣(qi)流(liu)分離。負極由不同斷(duan)面形狀的(de)金屬導(dao)線制成，叫(jiao)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)(de)性能受粉(fen)塵(chen)(chen)性質、設備構造和(he)煙氣流速等三個因素的(de)(de)(de)影響。粉(fen)塵(chen)(chen)的(de)(de)(de)比電(dian)阻是評價導電(dian)性的(de)(de)(de)指標，它對(dui)除(chu)塵(chen)(chen)效率有直接的(de)(de)(de)影響。比電(dian)阻過低(di)，塵(chen)(chen)粒難以保持在集(ji)塵(chen)(chen)電(dian)極(ji)上，致使其重返氣流。比電(dian)阻過高，到達集(ji)塵(chen)(chen)電(dian)極(ji)的(de)(de)(de)塵(chen)(chen)粒電(dian)荷(he)不易放出，在塵(chen)(chen)層之間形(xing)成電(dian)壓梯(ti)度會(hui)產生局(ju)部擊穿和(he)放電(dian)現象。這些(xie)情況都會(hui)造成除(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(ya)需(xu)保持40一(yi)75kV乃至100kV以(yi)上。

工作原理

電(dian)(dian)除塵(chen)器的(de)基本(ben)原理(li)是利用(yong)電(dian)(dian)力捕集煙氣中的(de)粉(fen)塵(chen)，主要包括以下四個相互有關的(de)物理(li)過程：（1）氣體的(de)電(dian)(dian)離。（2）粉(fen)塵(chen)的(de)荷電(dian)(dian)。（3）荷電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動(dong)。（4）荷電(dian)(dian)粉(fen)塵(chen)的(de)捕集。

荷電(dian)(dian)(dian)(dian)(dian)粉(fen)(fen)塵的(de)(de)(de)捕集過程：在(zai)(zai)兩個曲率半徑相(xiang)差(cha)較(jiao)大的(de)(de)(de)金屬陽極(ji)(ji)(ji)和(he)陰(yin)極(ji)(ji)(ji)上(shang)，通過高(gao)壓直流電(dian)(dian)(dian)(dian)(dian)，維持一個足(zu)以使(shi)氣體電(dian)(dian)(dian)(dian)(dian)離(li)(li)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)，氣體電(dian)(dian)(dian)(dian)(dian)離(li)(li)后所(suo)產生的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子：陰(yin)離(li)(li)子和(he)陽離(li)(li)子，吸附在(zai)(zai)通過電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)的(de)(de)(de)粉(fen)(fen)塵上(shang)，使(shi)粉(fen)(fen)塵獲得電(dian)(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)性(xing)不同(tong)(tong)的(de)(de)(de)粉(fen)(fen)塵在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)(chang)力的(de)(de)(de)作用下，分(fen)別(bie)向不同(tong)(tong)極(ji)(ji)(ji)性(xing)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)運動，沉積在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，而達到粉(fen)(fen)塵和(he)氣體分(fen)離(li)(li)的(de)(de)(de)目的(de)(de)(de)。

基本結構

靜(jing)電(dian)(dian)(dian)電(dian)(dian)(dian)除(chu)塵(chen)器由兩(liang)大(da)部(bu)(bu)分(fen)組成：一部(bu)(bu)分(fen)是電(dian)(dian)(dian)除(chu)塵(chen)器本體系統；另一部(bu)(bu)分(fen)是提供(gong)高(gao)壓直流(liu)電(dian)(dian)(dian)的(de)(de)供(gong)電(dian)(dian)(dian)裝置(zhi)和低壓自動(dong)控(kong)(kong)制系統。電(dian)(dian)(dian)除(chu)塵(chen)器的(de)(de)結構原理圖(tu)如圖(tu)1所示，高(gao)壓供(gong)電(dian)(dian)(dian)系統為升壓變壓器供(gong)電(dian)(dian)(dian)，除(chu)塵(chen)器集塵(chen)極(ji)接(jie)地(di)。低壓電(dian)(dian)(dian)控(kong)(kong)制系統用來控(kong)(kong)制電(dian)(dian)(dian)磁振打錘、卸灰(hui)電(dian)(dian)(dian)極(ji)、輸灰(hui)電(dian)(dian)(dian)極(ji)以及幾個部(bu)(bu)件的(de)(de)溫度(du)。
