遼陽靜電除塵器廠家

靜電除塵器的工作(zuo)原理是利(li)用高(gao)壓電(dian)(dian)場使煙氣發生電(dian)(dian)離，氣流中(zhong)的粉塵荷電(dian)(dian)在電(dian)(dian)場作(zuo)用下與(yu)氣流分離。負極(ji)由不(bu)同斷(duan)面形(xing)狀(zhuang)的金屬導線制成，叫放電(dian)(dian)電(dian)(dian)極(ji)。

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)(xing)能受粉(fen)塵(chen)性(xing)(xing)質、設備構造和(he)(he)煙(yan)氣流速等三個因素的影響。粉(fen)塵(chen)的比電(dian)(dian)阻(zu)(zu)是評價導電(dian)(dian)性(xing)(xing)的指標，它(ta)對除(chu)塵(chen)效(xiao)率有直接的影響。比電(dian)(dian)阻(zu)(zu)過低，塵(chen)粒(li)難以保持在集塵(chen)電(dian)(dian)極上，致(zhi)使其重返氣流。比電(dian)(dian)阻(zu)(zu)過高，到達集塵(chen)電(dian)(dian)極的塵(chen)粒(li)電(dian)(dian)荷不(bu)易放出，在塵(chen)層之(zhi)間形成(cheng)電(dian)(dian)壓(ya)梯度會(hui)產生局部擊穿和(he)(he)放電(dian)(dian)現象。這些情(qing)況都會(hui)造成(cheng)除(chu)塵(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需保持40一75kV乃至100kV以(yi)上。

工作原理

電(dian)(dian)除塵器(qi)的(de)基本原理是利(li)用電(dian)(dian)力捕集煙氣中的(de)粉塵，主要(yao)包括以下四個相互有(you)關的(de)物理過程：（1）氣體(ti)的(de)電(dian)(dian)離。（2）粉塵的(de)荷電(dian)(dian)。（3）荷電(dian)(dian)粉塵向電(dian)(dian)極移(yi)動。（4）荷電(dian)(dian)粉塵的(de)捕集。

荷(he)電粉塵(chen)的(de)捕集過程(cheng)：在(zai)兩個曲率半徑相差(cha)較(jiao)大的(de)金(jin)屬陽(yang)(yang)極(ji)和陰極(ji)上(shang)(shang)，通過高壓直流電，維持一個足(zu)以使(shi)氣體(ti)電離(li)(li)的(de)電場，氣體(ti)電離(li)(li)后所產生的(de)電子(zi)：陰離(li)(li)子(zi)和陽(yang)(yang)離(li)(li)子(zi)，吸附在(zai)通過電場的(de)粉塵(chen)上(shang)(shang)，使(shi)粉塵(chen)獲得電荷(he)。荷(he)電極(ji)性不同的(de)粉塵(chen)在(zai)電場力(li)的(de)作(zuo)用下，分(fen)別(bie)向不同極(ji)性的(de)電極(ji)運動，沉積(ji)在(zai)電極(ji)上(shang)(shang)，而達到粉塵(chen)和氣體(ti)分(fen)離(li)(li)的(de)目的(de)。

基本結構

靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)除塵器由(you)兩大部(bu)分組成(cheng)：一部(bu)分是電(dian)(dian)(dian)(dian)(dian)(dian)除塵器本(ben)體系統；另一部(bu)分是提供高(gao)壓(ya)直流電(dian)(dian)(dian)(dian)(dian)(dian)的供電(dian)(dian)(dian)(dian)(dian)(dian)裝置和低壓(ya)自動控制系統。電(dian)(dian)(dian)(dian)(dian)(dian)除塵器的結(jie)構(gou)原理圖如圖1所示，高(gao)壓(ya)供電(dian)(dian)(dian)(dian)(dian)(dian)系統為(wei)升壓(ya)變壓(ya)器供電(dian)(dian)(dian)(dian)(dian)(dian)，除塵器集塵極(ji)接地(di)。低壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)控制系統用來控制電(dian)(dian)(dian)(dian)(dian)(dian)磁振打錘、卸灰電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)、輸灰電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)以及幾個(ge)部(bu)件(jian)的溫度。
