青島靜電除塵器廠家

靜電除塵器的工(gong)作原理是(shi)利用高壓電(dian)(dian)場使(shi)煙(yan)氣發(fa)生電(dian)(dian)離，氣流中的粉(fen)塵(chen)荷電(dian)(dian)在電(dian)(dian)場作用下與氣流分離。負極由(you)不同斷面形狀的金屬導線制(zhi)成，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(de)(de)性能受粉塵(chen)(chen)(chen)性質、設備構(gou)造和煙氣流(liu)速等三(san)個因(yin)素的(de)(de)影響(xiang)。粉塵(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)阻是評(ping)價導電(dian)(dian)性的(de)(de)指標，它(ta)對除塵(chen)(chen)(chen)效率(lv)有直接的(de)(de)影響(xiang)。比(bi)電(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以(yi)保持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)極(ji)上，致使其重(zhong)返氣流(liu)。比(bi)電(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)易放出(chu)，在塵(chen)(chen)(chen)層之(zhi)間(jian)形(xing)成電(dian)(dian)壓(ya)梯度(du)會產生局部擊穿和放電(dian)(dian)現(xian)象(xiang)。這些情況都會造成除塵(chen)(chen)(chen)效率(lv)下降(jiang)。

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(yi)上。

工作原理

電除塵器(qi)的基(ji)本原理是(shi)利用電力捕集煙氣(qi)中的粉塵，主要(yao)包括以(yi)下四(si)個相互有關的物理過程：（1）氣(qi)體的電離。（2）粉塵的荷電。（3）荷電粉塵向電極移動。（4）荷電粉塵的捕集。

荷(he)電(dian)(dian)(dian)(dian)(dian)粉塵的(de)(de)捕(bu)集過(guo)程：在(zai)兩個(ge)曲率半徑相差較大的(de)(de)金屬陽極和陰極上(shang)，通過(guo)高壓直流電(dian)(dian)(dian)(dian)(dian)，維持一個(ge)足以使(shi)(shi)氣體電(dian)(dian)(dian)(dian)(dian)離(li)的(de)(de)電(dian)(dian)(dian)(dian)(dian)場，氣體電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)所產生的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)：陰離(li)子(zi)和陽離(li)子(zi)，吸附在(zai)通過(guo)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉塵上(shang)，使(shi)(shi)粉塵獲得電(dian)(dian)(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)(dian)(dian)極性(xing)不(bu)同(tong)(tong)的(de)(de)粉塵在(zai)電(dian)(dian)(dian)(dian)(dian)場力(li)的(de)(de)作用(yong)下，分(fen)別向不(bu)同(tong)(tong)極性(xing)的(de)(de)電(dian)(dian)(dian)(dian)(dian)極運(yun)動(dong)，沉積在(zai)電(dian)(dian)(dian)(dian)(dian)極上(shang)，而(er)達到粉塵和氣體分(fen)離(li)的(de)(de)目的(de)(de)。

基本結構

靜電(dian)(dian)(dian)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)由兩大部分組成(cheng)：一部分是電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)本體系統；另一部分是提供高壓(ya)直流電(dian)(dian)(dian)的供電(dian)(dian)(dian)裝置和低壓(ya)自動控制(zhi)系統。電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的結(jie)構原(yuan)理圖如圖1所示，高壓(ya)供電(dian)(dian)(dian)系統為(wei)升(sheng)壓(ya)變壓(ya)器(qi)供電(dian)(dian)(dian)，除(chu)(chu)塵(chen)(chen)(chen)器(qi)集(ji)塵(chen)(chen)(chen)極接地(di)。低壓(ya)電(dian)(dian)(dian)控制(zhi)系統用來控制(zhi)電(dian)(dian)(dian)磁振(zhen)打錘、卸灰(hui)電(dian)(dian)(dian)極、輸灰(hui)電(dian)(dian)(dian)極以及(ji)幾個部件的溫度。
