阿勒泰靜電除塵器廠家

靜電除塵器的(de)工(gong)作(zuo)原理是利用高壓電(dian)場使煙氣(qi)發(fa)生電(dian)離(li)，氣(qi)流中的(de)粉塵荷電(dian)在電(dian)場作(zuo)用下與氣(qi)流分(fen)離(li)。負極由不同(tong)斷面(mian)形狀的(de)金屬導線制成，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)性(xing)(xing)能受粉塵(chen)(chen)性(xing)(xing)質、設備構造和煙氣流速等三個因素的(de)影(ying)響(xiang)。粉塵(chen)(chen)的(de)比(bi)電(dian)(dian)阻(zu)(zu)是(shi)評(ping)價導(dao)電(dian)(dian)性(xing)(xing)的(de)指(zhi)標，它對除塵(chen)(chen)效(xiao)(xiao)率(lv)有(you)直接的(de)影(ying)響(xiang)。比(bi)電(dian)(dian)阻(zu)(zu)過低(di)，塵(chen)(chen)粒難以保持在集塵(chen)(chen)電(dian)(dian)極上，致使其(qi)重返氣流。比(bi)電(dian)(dian)阻(zu)(zu)過高，到達集塵(chen)(chen)電(dian)(dian)極的(de)塵(chen)(chen)粒電(dian)(dian)荷不易放出，在塵(chen)(chen)層之間形成電(dian)(dian)壓梯度會產生局部擊穿和放電(dian)(dian)現象。這(zhe)些(xie)情(qing)況(kuang)都會造成除塵(chen)(chen)效(xiao)(xiao)率(lv)下(xia)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需保持(chi)40一75kV乃(nai)至100kV以上。

工作原理

電(dian)除(chu)塵器的基本(ben)原(yuan)理是利用電(dian)力(li)捕(bu)集煙氣中的粉(fen)(fen)(fen)塵，主要(yao)包括以下四個相互有關的物理過程：（1）氣體的電(dian)離。（2）粉(fen)(fen)(fen)塵的荷(he)電(dian)。（3）荷(he)電(dian)粉(fen)(fen)(fen)塵向電(dian)極(ji)移動(dong)。（4）荷(he)電(dian)粉(fen)(fen)(fen)塵的捕(bu)集。

荷(he)(he)電(dian)(dian)(dian)粉(fen)塵(chen)(chen)的捕(bu)集過程：在(zai)兩個曲率半徑相差較大的金屬陽極(ji)(ji)和(he)陰(yin)極(ji)(ji)上，通(tong)過高壓直流(liu)電(dian)(dian)(dian)，維持一個足以使氣(qi)(qi)體(ti)電(dian)(dian)(dian)離(li)的電(dian)(dian)(dian)場，氣(qi)(qi)體(ti)電(dian)(dian)(dian)離(li)后所產生的電(dian)(dian)(dian)子：陰(yin)離(li)子和(he)陽離(li)子，吸(xi)附在(zai)通(tong)過電(dian)(dian)(dian)場的粉(fen)塵(chen)(chen)上，使粉(fen)塵(chen)(chen)獲得電(dian)(dian)(dian)荷(he)(he)。荷(he)(he)電(dian)(dian)(dian)極(ji)(ji)性不同的粉(fen)塵(chen)(chen)在(zai)電(dian)(dian)(dian)場力的作用下(xia)，分(fen)別向不同極(ji)(ji)性的電(dian)(dian)(dian)極(ji)(ji)運動，沉積(ji)在(zai)電(dian)(dian)(dian)極(ji)(ji)上，而達(da)到(dao)粉(fen)塵(chen)(chen)和(he)氣(qi)(qi)體(ti)分(fen)離(li)的目的。
