臨沂靜電除塵器廠家

靜電除塵器的(de)(de)工作原理是(shi)利用高(gao)壓(ya)電(dian)(dian)場使煙氣(qi)(qi)發生電(dian)(dian)離(li)，氣(qi)(qi)流中的(de)(de)粉塵荷(he)電(dian)(dian)在(zai)電(dian)(dian)場作用下與氣(qi)(qi)流分離(li)。負(fu)極由不(bu)同斷面形狀的(de)(de)金屬(shu)導線制成(cheng)，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。靜電除塵器廠家的性(xing)能受粉塵(chen)(chen)(chen)(chen)性(xing)質、設備構造(zao)和(he)煙氣流速等三個因(yin)素(su)的影(ying)響(xiang)。粉塵(chen)(chen)(chen)(chen)的比(bi)電(dian)(dian)阻(zu)是評價導電(dian)(dian)性(xing)的指標(biao)，它對(dui)除(chu)塵(chen)(chen)(chen)(chen)效率有直(zhi)接(jie)的影(ying)響(xiang)。比(bi)電(dian)(dian)阻(zu)過低，塵(chen)(chen)(chen)(chen)粒(li)難以保持在(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)上，致(zhi)使其重返(fan)氣流。比(bi)電(dian)(dian)阻(zu)過高，到達(da)集塵(chen)(chen)(chen)(chen)電(dian)(dian)極(ji)的塵(chen)(chen)(chen)(chen)粒(li)電(dian)(dian)荷(he)不易放出，在(zai)塵(chen)(chen)(chen)(chen)層之間(jian)形成電(dian)(dian)壓(ya)梯度會產生局部擊穿和(he)放電(dian)(dian)現象。這(zhe)些情況都會造(zao)成除(chu)塵(chen)(chen)(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，靜電除塵器運行(xing)電壓需保持40一75kV乃至100kV以上。

工作原理

電(dian)除塵(chen)(chen)(chen)器的(de)(de)基(ji)本原理是利用電(dian)力捕(bu)集(ji)(ji)煙氣(qi)中的(de)(de)粉塵(chen)(chen)(chen)，主(zhu)要包括以下四個相互有關的(de)(de)物理過程：（1）氣(qi)體(ti)的(de)(de)電(dian)離。（2）粉塵(chen)(chen)(chen)的(de)(de)荷電(dian)。（3）荷電(dian)粉塵(chen)(chen)(chen)向電(dian)極(ji)移動。（4）荷電(dian)粉塵(chen)(chen)(chen)的(de)(de)捕(bu)集(ji)(ji)。

荷電(dian)(dian)(dian)(dian)粉塵(chen)的(de)(de)捕集過(guo)程：在(zai)兩個(ge)曲率半徑相差較大(da)的(de)(de)金屬陽(yang)極(ji)(ji)和陰極(ji)(ji)上，通過(guo)高(gao)壓直流電(dian)(dian)(dian)(dian)，維(wei)持一個(ge)足以使氣(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離(li)的(de)(de)電(dian)(dian)(dian)(dian)場，氣(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)離(li)后所(suo)產生的(de)(de)電(dian)(dian)(dian)(dian)子(zi)：陰離(li)子(zi)和陽(yang)離(li)子(zi)，吸附在(zai)通過(guo)電(dian)(dian)(dian)(dian)場的(de)(de)粉塵(chen)上，使粉塵(chen)獲得電(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)極(ji)(ji)性不同的(de)(de)粉塵(chen)在(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)作用下，分(fen)別向不同極(ji)(ji)性的(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)運(yun)動，沉積在(zai)電(dian)(dian)(dian)(dian)極(ji)(ji)上，而達到粉塵(chen)和氣(qi)體(ti)(ti)分(fen)離(li)的(de)(de)目的(de)(de)。

基本結構

靜電(dian)(dian)電(dian)(dian)除塵(chen)(chen)器由兩大部分(fen)組成：一(yi)部分(fen)是電(dian)(dian)除塵(chen)(chen)器本體系統；另一(yi)部分(fen)是提供(gong)高壓(ya)直流(liu)電(dian)(dian)的供(gong)電(dian)(dian)裝置和(he)低壓(ya)自動控(kong)(kong)制系統。電(dian)(dian)除塵(chen)(chen)器的結構原理(li)圖(tu)如(ru)圖(tu)1所示(shi)，高壓(ya)供(gong)電(dian)(dian)系統為升壓(ya)變壓(ya)器供(gong)電(dian)(dian)，除塵(chen)(chen)器集塵(chen)(chen)極接(jie)地。低壓(ya)電(dian)(dian)控(kong)(kong)制系統用(yong)來控(kong)(kong)制電(dian)(dian)磁振打錘(chui)、卸(xie)灰(hui)電(dian)(dian)極、輸灰(hui)電(dian)(dian)極以及幾個部件的溫度。
