玉樹靜電除塵器廠家

靜電除塵器的(de)工作(zuo)(zuo)原理是利用高壓電(dian)(dian)場(chang)使(shi)煙氣(qi)發生電(dian)(dian)離，氣(qi)流中的(de)粉(fen)塵荷電(dian)(dian)在電(dian)(dian)場(chang)作(zuo)(zuo)用下與(yu)氣(qi)流分離。負極(ji)由不同斷面形狀的(de)金(jin)屬導線(xian)制成，叫(jiao)放電(dian)(dian)電(dian)(dian)極(ji)。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的性(xing)能受粉塵(chen)(chen)(chen)(chen)(chen)性(xing)質、設(she)備構造(zao)和煙氣(qi)流(liu)速等三個因素的影響(xiang)。粉塵(chen)(chen)(chen)(chen)(chen)的比電阻(zu)(zu)是(shi)評價導電性(xing)的指標，它(ta)對除(chu)塵(chen)(chen)(chen)(chen)(chen)效率有(you)直(zhi)接的影響(xiang)。比電阻(zu)(zu)過(guo)低，塵(chen)(chen)(chen)(chen)(chen)粒難以保持(chi)在(zai)集(ji)塵(chen)(chen)(chen)(chen)(chen)電極上，致使其重返氣(qi)流(liu)。比電阻(zu)(zu)過(guo)高，到(dao)達集(ji)塵(chen)(chen)(chen)(chen)(chen)電極的塵(chen)(chen)(chen)(chen)(chen)粒電荷不易放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)(chen)層之間(jian)形成電壓梯度會產生局部擊穿和放(fang)電現象。這些情況都會造(zao)成除(chu)塵(chen)(chen)(chen)(chen)(chen)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，靜電除塵器運行電壓需(xu)保持40一75kV乃至100kV以上。

工作原理

電(dian)除塵(chen)(chen)器的(de)(de)基(ji)本原理是利用電(dian)力(li)捕(bu)(bu)集煙氣中的(de)(de)粉塵(chen)(chen)，主要包括以下四(si)個(ge)相(xiang)互有關的(de)(de)物理過程：（1）氣體的(de)(de)電(dian)離。（2）粉塵(chen)(chen)的(de)(de)荷電(dian)。（3）荷電(dian)粉塵(chen)(chen)向電(dian)極(ji)移動。（4）荷電(dian)粉塵(chen)(chen)的(de)(de)捕(bu)(bu)集。

荷(he)電(dian)(dian)粉塵(chen)(chen)(chen)的(de)捕集過程：在兩個(ge)曲(qu)率半徑相差較大的(de)金屬陽極(ji)和(he)陰極(ji)上(shang)，通過高壓直流電(dian)(dian)，維持一(yi)個(ge)足以使(shi)氣(qi)體(ti)(ti)電(dian)(dian)離(li)的(de)電(dian)(dian)場，氣(qi)體(ti)(ti)電(dian)(dian)離(li)后所產生的(de)電(dian)(dian)子：陰離(li)子和(he)陽離(li)子，吸附在通過電(dian)(dian)場的(de)粉塵(chen)(chen)(chen)上(shang)，使(shi)粉塵(chen)(chen)(chen)獲得電(dian)(dian)荷(he)。荷(he)電(dian)(dian)極(ji)性(xing)不同的(de)粉塵(chen)(chen)(chen)在電(dian)(dian)場力的(de)作(zuo)用下，分別向不同極(ji)性(xing)的(de)電(dian)(dian)極(ji)運動，沉積在電(dian)(dian)極(ji)上(shang)，而(er)達到(dao)粉塵(chen)(chen)(chen)和(he)氣(qi)體(ti)(ti)分離(li)的(de)目的(de)。
