贛州靜電除塵器廠家

靜電除塵器的(de)工作(zuo)(zuo)原理是利(li)用(yong)(yong)高壓電場使煙氣發生電離，氣流(liu)中的(de)粉(fen)塵荷電在電場作(zuo)(zuo)用(yong)(yong)下與氣流(liu)分離。負極(ji)由(you)不同斷(duan)面(mian)形狀的(de)金屬導(dao)線制成，叫(jiao)放電電極(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(de)(de)(de)性(xing)能受(shou)粉塵(chen)(chen)性(xing)質、設備構造和煙氣(qi)(qi)流速等三個(ge)因素的(de)(de)(de)影(ying)(ying)響。粉塵(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)性(xing)的(de)(de)(de)指(zhi)標，它對除塵(chen)(chen)效率(lv)有直接的(de)(de)(de)影(ying)(ying)響。比電(dian)(dian)(dian)阻過低(di)，塵(chen)(chen)粒難以保持在集塵(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其(qi)重返氣(qi)(qi)流。比電(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不(bu)易放(fang)出，在塵(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)壓梯(ti)度會(hui)(hui)產生局部(bu)擊穿和放(fang)電(dian)(dian)(dian)現(xian)象。這些情況都會(hui)(hui)造成(cheng)除塵(chen)(chen)效率(lv)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40一75kV乃至100kV以上。

工作原理

電(dian)(dian)除塵器的(de)基本原理(li)是利用電(dian)(dian)力捕(bu)(bu)集煙氣(qi)中的(de)粉塵，主(zhu)要包括以下四個相互有(you)關的(de)物理(li)過程(cheng)：（1）氣(qi)體的(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)極移動。（4）荷電(dian)(dian)粉塵的(de)捕(bu)(bu)集。

荷(he)電(dian)粉(fen)(fen)塵的捕集過程(cheng)：在兩個曲(qu)率半徑相差較(jiao)大(da)的金屬(shu)陽(yang)極(ji)和(he)陰極(ji)上(shang)，通過高(gao)壓直流電(dian)，維持一個足以使氣體電(dian)離(li)的電(dian)場，氣體電(dian)離(li)后所(suo)產生的電(dian)子(zi)：陰離(li)子(zi)和(he)陽(yang)離(li)子(zi)，吸附在通過電(dian)場的粉(fen)(fen)塵上(shang)，使粉(fen)(fen)塵獲得電(dian)荷(he)。荷(he)電(dian)極(ji)性(xing)不(bu)同(tong)的粉(fen)(fen)塵在電(dian)場力的作(zuo)用下，分別向不(bu)同(tong)極(ji)性(xing)的電(dian)極(ji)運動，沉積在電(dian)極(ji)上(shang)，而達到(dao)粉(fen)(fen)塵和(he)氣體分離(li)的目的。

靜電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器由(you)兩大(da)部(bu)分組成：一部(bu)分是電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器本體系(xi)(xi)統(tong)(tong)；另(ling)一部(bu)分是提供高壓直(zhi)流電(dian)(dian)(dian)(dian)的供電(dian)(dian)(dian)(dian)裝置和低(di)壓自動控制(zhi)系(xi)(xi)統(tong)(tong)。電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的結構原(yuan)理(li)圖(tu)如圖(tu)1所示，高壓供電(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)(tong)為升壓變壓器供電(dian)(dian)(dian)(dian)，除(chu)塵(chen)(chen)器集塵(chen)(chen)極接地。低(di)壓電(dian)(dian)(dian)(dian)控制(zhi)系(xi)(xi)統(tong)(tong)用(yong)來控制(zhi)電(dian)(dian)(dian)(dian)磁振打錘(chui)、卸灰電(dian)(dian)(dian)(dian)極、輸(shu)灰電(dian)(dian)(dian)(dian)極以及幾個部(bu)件(jian)的溫度。
