滄州靜電除塵器廠家

靜電除塵器的(de)工(gong)作原(yuan)理是(shi)利用(yong)(yong)高壓電(dian)場使煙氣(qi)發生(sheng)電(dian)離，氣(qi)流中的(de)粉塵荷電(dian)在電(dian)場作用(yong)(yong)下與氣(qi)流分離。負極由不同斷面形狀的(de)金屬(shu)導線制成，叫放電(dian)電(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(neng)受粉(fen)塵(chen)(chen)(chen)性質、設備構造(zao)和煙(yan)氣流(liu)(liu)速等三個(ge)因素的(de)(de)影(ying)(ying)響。粉(fen)塵(chen)(chen)(chen)的(de)(de)比電(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)性的(de)(de)指標，它對除塵(chen)(chen)(chen)效(xiao)率(lv)有(you)直接(jie)的(de)(de)影(ying)(ying)響。比電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒(li)(li)難以保持(chi)在(zai)集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其重返氣流(liu)(liu)。比電(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)塵(chen)(chen)(chen)粒(li)(li)電(dian)(dian)(dian)荷不易放出(chu)，在(zai)塵(chen)(chen)(chen)層之間形成電(dian)(dian)(dian)壓梯度會(hui)產生(sheng)局部擊(ji)穿和放電(dian)(dian)(dian)現象。這(zhe)些情況都會(hui)造(zao)成除塵(chen)(chen)(chen)效(xiao)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(xing)電(dian)壓需(xu)保持40一(yi)75kV乃至(zhi)100kV以上。

工作原理

電除塵(chen)器的(de)(de)(de)基(ji)本原理(li)是利用電力(li)捕(bu)集煙氣中(zhong)的(de)(de)(de)粉(fen)塵(chen)，主要包括以下(xia)四(si)個(ge)相互有關的(de)(de)(de)物(wu)理(li)過程(cheng)：（1）氣體的(de)(de)(de)電離(li)。（2）粉(fen)塵(chen)的(de)(de)(de)荷(he)電。（3）荷(he)電粉(fen)塵(chen)向電極(ji)移動(dong)。（4）荷(he)電粉(fen)塵(chen)的(de)(de)(de)捕(bu)集。

荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)粉塵的(de)(de)捕集(ji)過程：在(zai)(zai)兩個(ge)曲率半徑相差較大的(de)(de)金屬陽極(ji)(ji)(ji)和(he)陰(yin)(yin)極(ji)(ji)(ji)上(shang)，通過高壓(ya)直流電(dian)(dian)(dian)(dian)(dian)(dian)，維持(chi)一個(ge)足以(yi)使(shi)(shi)氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)場，氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)后(hou)所產生(sheng)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)：陰(yin)(yin)離(li)子(zi)和(he)陽離(li)子(zi)，吸(xi)附在(zai)(zai)通過電(dian)(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)(dian)荷(he)。荷(he)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)性(xing)不(bu)同的(de)(de)粉塵在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作(zuo)用下，分別向不(bu)同極(ji)(ji)(ji)性(xing)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)運動，沉積在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，而達到粉塵和(he)氣(qi)體(ti)分離(li)的(de)(de)目的(de)(de)。

基本結構

靜(jing)電(dian)(dian)(dian)電(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)由兩大部分組成(cheng)：一(yi)部分是電(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)本(ben)體(ti)系統；另一(yi)部分是提供高(gao)(gao)壓(ya)直流電(dian)(dian)(dian)的供電(dian)(dian)(dian)裝置(zhi)和(he)低壓(ya)自動控(kong)制系統。電(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)的結構原(yuan)理圖如圖1所示，高(gao)(gao)壓(ya)供電(dian)(dian)(dian)系統為升壓(ya)變壓(ya)器(qi)(qi)供電(dian)(dian)(dian)，除(chu)塵(chen)器(qi)(qi)集塵(chen)極接地。低壓(ya)電(dian)(dian)(dian)控(kong)制系統用來控(kong)制電(dian)(dian)(dian)磁振打錘、卸灰(hui)電(dian)(dian)(dian)極、輸灰(hui)電(dian)(dian)(dian)極以及幾個部件的溫度。
