克孜勒蘇柯爾克孜靜電除塵器廠家

靜電除塵器的(de)工作原(yuan)理(li)是利(li)用(yong)(yong)高(gao)壓電(dian)(dian)場使煙氣發生電(dian)(dian)離，氣流中的(de)粉塵荷電(dian)(dian)在電(dian)(dian)場作用(yong)(yong)下與氣流分離。負極由不(bu)同斷面(mian)形狀的(de)金屬導線(xian)制成(cheng)，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。靜電除塵器廠家的性(xing)能受粉塵(chen)(chen)(chen)性(xing)質、設備構造(zao)和煙氣(qi)流速等(deng)三個因(yin)素的影響。粉塵(chen)(chen)(chen)的比電(dian)(dian)阻是評價導電(dian)(dian)性(xing)的指(zhi)標，它對(dui)除塵(chen)(chen)(chen)效率(lv)有直接的影響。比電(dian)(dian)阻過(guo)低，塵(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)電(dian)(dian)極(ji)上(shang)，致使其重返氣(qi)流。比電(dian)(dian)阻過(guo)高，到達(da)集塵(chen)(chen)(chen)電(dian)(dian)極(ji)的塵(chen)(chen)(chen)粒電(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)層之間形成(cheng)電(dian)(dian)壓梯度會產(chan)生局部擊穿和放(fang)電(dian)(dian)現象。這(zhe)些情況(kuang)都(dou)會造(zao)成(cheng)除塵(chen)(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，靜電除塵器運行電壓(ya)需保(bao)持(chi)40一(yi)75kV乃至100kV以上。

工作原理

電(dian)(dian)除塵(chen)器的(de)(de)(de)基(ji)本(ben)原理是利用電(dian)(dian)力捕集煙氣(qi)中的(de)(de)(de)粉(fen)塵(chen)，主要包括以下四個(ge)相互有關的(de)(de)(de)物理過程(cheng)：（1）氣(qi)體的(de)(de)(de)電(dian)(dian)離。（2）粉(fen)塵(chen)的(de)(de)(de)荷(he)電(dian)(dian)。（3）荷(he)電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動。（4）荷(he)電(dian)(dian)粉(fen)塵(chen)的(de)(de)(de)捕集。

荷(he)電(dian)粉(fen)(fen)塵的(de)(de)捕(bu)集過程：在(zai)兩個曲率(lv)半徑相差較大的(de)(de)金屬陽極(ji)和陰極(ji)上，通(tong)過高壓(ya)直流(liu)電(dian)，維(wei)持一個足以(yi)使(shi)氣體電(dian)離(li)的(de)(de)電(dian)場，氣體電(dian)離(li)后所(suo)產生的(de)(de)電(dian)子：陰離(li)子和陽離(li)子，吸(xi)附在(zai)通(tong)過電(dian)場的(de)(de)粉(fen)(fen)塵上，使(shi)粉(fen)(fen)塵獲得(de)電(dian)荷(he)。荷(he)電(dian)極(ji)性(xing)不(bu)同的(de)(de)粉(fen)(fen)塵在(zai)電(dian)場力的(de)(de)作用下，分別向不(bu)同極(ji)性(xing)的(de)(de)電(dian)極(ji)運動，沉積在(zai)電(dian)極(ji)上，而達到(dao)粉(fen)(fen)塵和氣體分離(li)的(de)(de)目的(de)(de)。
