永州靜電除塵器廠家

靜電除塵器的(de)工作原理是利用高壓電(dian)場(chang)使煙氣發(fa)生(sheng)電(dian)離，氣流中的(de)粉塵荷電(dian)在電(dian)場(chang)作用下與氣流分離。負極(ji)由不同(tong)斷面形狀的(de)金屬導線制成(cheng)，叫(jiao)放電(dian)電(dian)極(ji)。

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)(de)性(xing)(xing)能受(shou)粉塵性(xing)(xing)質(zhi)、設備構造和(he)煙氣(qi)流速等三個因素的(de)(de)(de)影響。粉塵的(de)(de)(de)比(bi)電(dian)阻是(shi)評價導電(dian)性(xing)(xing)的(de)(de)(de)指標(biao)，它對除塵效率有直(zhi)接(jie)的(de)(de)(de)影響。比(bi)電(dian)阻過低，塵粒難以保持(chi)在集(ji)塵電(dian)極上，致使其重(zhong)返氣(qi)流。比(bi)電(dian)阻過高，到達集(ji)塵電(dian)極的(de)(de)(de)塵粒電(dian)荷不易放出，在塵層之間(jian)形成(cheng)電(dian)壓梯度會產生局部擊穿和(he)放電(dian)現象。這些情況都會造成(cheng)除塵效率下降。

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(yun)行電壓需(xu)保持40一(yi)75kV乃至100kV以上(shang)。

工作原理

電(dian)除(chu)塵(chen)器的(de)(de)(de)基本原(yuan)理是利用電(dian)力捕集煙氣中的(de)(de)(de)粉塵(chen)，主要(yao)包括以下四個相互有關的(de)(de)(de)物理過程：（1）氣體(ti)的(de)(de)(de)電(dian)離。（2）粉塵(chen)的(de)(de)(de)荷(he)電(dian)。（3）荷(he)電(dian)粉塵(chen)向電(dian)極移(yi)動。（4）荷(he)電(dian)粉塵(chen)的(de)(de)(de)捕集。

荷電(dian)(dian)(dian)(dian)(dian)粉塵的(de)(de)捕(bu)集過(guo)程：在兩個曲率(lv)半徑相差較大(da)的(de)(de)金屬(shu)陽(yang)極(ji)(ji)和陰極(ji)(ji)上，通(tong)過(guo)高壓直(zhi)流電(dian)(dian)(dian)(dian)(dian)，維持(chi)一個足以使氣體電(dian)(dian)(dian)(dian)(dian)離(li)(li)的(de)(de)電(dian)(dian)(dian)(dian)(dian)場，氣體電(dian)(dian)(dian)(dian)(dian)離(li)(li)后所產(chan)生(sheng)的(de)(de)電(dian)(dian)(dian)(dian)(dian)子：陰離(li)(li)子和陽(yang)離(li)(li)子，吸附(fu)在通(tong)過(guo)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)粉塵上，使粉塵獲得電(dian)(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)性(xing)不(bu)同的(de)(de)粉塵在電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)作用(yong)下，分別向不(bu)同極(ji)(ji)性(xing)的(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)運動，沉積在電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上，而(er)達到(dao)粉塵和氣體分離(li)(li)的(de)(de)目(mu)的(de)(de)。
