景德鎮靜電除塵器廠家

靜電除塵器的(de)工作原理是利用高壓電場使煙氣(qi)發生電離，氣(qi)流中的(de)粉(fen)塵(chen)荷電在電場作用下與氣(qi)流分離。負極由不同斷面形狀的(de)金屬導線制成，叫放電電極。

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能(neng)受粉塵(chen)(chen)(chen)(chen)性質、設備(bei)構造和(he)煙氣(qi)流(liu)(liu)速等三個(ge)因(yin)素的影響(xiang)。粉塵(chen)(chen)(chen)(chen)的比電(dian)(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)(dian)性的指(zhi)標(biao)，它對除塵(chen)(chen)(chen)(chen)效(xiao)率有直接的影響(xiang)。比電(dian)(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)(chen)粒難以(yi)保持在集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上，致使(shi)其(qi)重返氣(qi)流(liu)(liu)。比電(dian)(dian)(dian)(dian)阻過(guo)高，到達(da)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)壓梯度會(hui)產生局部擊穿和(he)放電(dian)(dian)(dian)(dian)現象(xiang)。這些情況(kuang)都會(hui)造成(cheng)除塵(chen)(chen)(chen)(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(dian)壓需(xu)保(bao)持40一75kV乃(nai)至100kV以(yi)上。

工作原理

電(dian)除塵(chen)(chen)器的(de)(de)基本(ben)原(yuan)理是利用電(dian)力捕(bu)集煙氣中的(de)(de)粉(fen)塵(chen)(chen)，主要包括以(yi)下四個相互有關的(de)(de)物(wu)理過(guo)程：（1）氣體的(de)(de)電(dian)離。（2）粉(fen)塵(chen)(chen)的(de)(de)荷(he)電(dian)。（3）荷(he)電(dian)粉(fen)塵(chen)(chen)向電(dian)極移動(dong)。（4）荷(he)電(dian)粉(fen)塵(chen)(chen)的(de)(de)捕(bu)集。

荷電(dian)(dian)(dian)(dian)(dian)粉塵(chen)(chen)(chen)的(de)(de)捕集(ji)過(guo)程：在(zai)兩(liang)個曲(qu)率半徑(jing)相差較大的(de)(de)金屬陽(yang)極(ji)(ji)和陰極(ji)(ji)上(shang)，通過(guo)高壓直流電(dian)(dian)(dian)(dian)(dian)，維持一個足以使(shi)氣(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離(li)的(de)(de)電(dian)(dian)(dian)(dian)(dian)場(chang)，氣(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離(li)后所產生的(de)(de)電(dian)(dian)(dian)(dian)(dian)子：陰離(li)子和陽(yang)離(li)子，吸附在(zai)通過(guo)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉塵(chen)(chen)(chen)上(shang)，使(shi)粉塵(chen)(chen)(chen)獲得電(dian)(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)性不同的(de)(de)粉塵(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用(yong)下，分(fen)(fen)別向不同極(ji)(ji)性的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)運動，沉積在(zai)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)，而達到(dao)粉塵(chen)(chen)(chen)和氣(qi)(qi)體分(fen)(fen)離(li)的(de)(de)目的(de)(de)。

基本結構

靜電電除塵(chen)器(qi)(qi)(qi)(qi)由兩大部(bu)(bu)分組成(cheng)：一部(bu)(bu)分是電除塵(chen)器(qi)(qi)(qi)(qi)本(ben)體(ti)系統(tong)；另一部(bu)(bu)分是提供高壓(ya)直流電的供電裝置和(he)低(di)壓(ya)自(zi)動控(kong)制系統(tong)。電除塵(chen)器(qi)(qi)(qi)(qi)的結構原理圖(tu)如圖(tu)1所示，高壓(ya)供電系統(tong)為升壓(ya)變壓(ya)器(qi)(qi)(qi)(qi)供電，除塵(chen)器(qi)(qi)(qi)(qi)集塵(chen)極接地(di)。低(di)壓(ya)電控(kong)制系統(tong)用(yong)來控(kong)制電磁振打錘、卸灰電極、輸灰電極以及幾個部(bu)(bu)件的溫度(du)。
