河池靜電除塵器廠家

靜電除塵器的工作原(yuan)理(li)是利(li)用(yong)高壓電(dian)(dian)場使煙氣(qi)發(fa)生電(dian)(dian)離，氣(qi)流中的粉塵荷電(dian)(dian)在電(dian)(dian)場作用(yong)下與(yu)氣(qi)流分離。負極(ji)由(you)不同斷面(mian)形(xing)狀的金(jin)屬導線(xian)制(zhi)成，叫放電(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(de)性能受粉(fen)塵(chen)(chen)(chen)(chen)性質、設備構造(zao)和煙氣流(liu)速等(deng)三(san)個因素的(de)影(ying)響。粉(fen)塵(chen)(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)性的(de)指標，它對除塵(chen)(chen)(chen)(chen)效(xiao)率有直(zhi)接的(de)影(ying)響。比(bi)電(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)(chen)粒難以保持(chi)在(zai)(zai)集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極上(shang)，致使其重返(fan)氣流(liu)。比(bi)電(dian)(dian)(dian)阻過高，到(dao)達集塵(chen)(chen)(chen)(chen)電(dian)(dian)(dian)極的(de)塵(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)荷不易放(fang)出，在(zai)(zai)塵(chen)(chen)(chen)(chen)層之(zhi)間形成(cheng)電(dian)(dian)(dian)壓(ya)梯(ti)度會(hui)產生局(ju)部擊穿和放(fang)電(dian)(dian)(dian)現象。這些情(qing)況都(dou)會(hui)造(zao)成(cheng)除塵(chen)(chen)(chen)(chen)效(xiao)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保持40一75kV乃(nai)至100kV以上。

工作原理

電(dian)(dian)(dian)除塵器的(de)基本原理(li)是利用電(dian)(dian)(dian)力(li)捕(bu)集煙氣中的(de)粉(fen)塵，主要包括(kuo)以下四個相互有關的(de)物理(li)過程：（1）氣體的(de)電(dian)(dian)(dian)離(li)。（2）粉(fen)塵的(de)荷(he)電(dian)(dian)(dian)。（3）荷(he)電(dian)(dian)(dian)粉(fen)塵向電(dian)(dian)(dian)極移動(dong)。（4）荷(he)電(dian)(dian)(dian)粉(fen)塵的(de)捕(bu)集。

荷電(dian)粉(fen)塵的(de)(de)(de)捕集過(guo)程：在(zai)兩個(ge)曲率半徑相(xiang)差較大的(de)(de)(de)金(jin)屬(shu)陽極(ji)(ji)和陰極(ji)(ji)上，通過(guo)高(gao)壓直流電(dian)，維持一(yi)個(ge)足(zu)以使氣(qi)體(ti)電(dian)離的(de)(de)(de)電(dian)場，氣(qi)體(ti)電(dian)離后所(suo)產生的(de)(de)(de)電(dian)子：陰離子和陽離子，吸附(fu)在(zai)通過(guo)電(dian)場的(de)(de)(de)粉(fen)塵上，使粉(fen)塵獲得電(dian)荷。荷電(dian)極(ji)(ji)性不同的(de)(de)(de)粉(fen)塵在(zai)電(dian)場力的(de)(de)(de)作(zuo)用下，分別(bie)向(xiang)不同極(ji)(ji)性的(de)(de)(de)電(dian)極(ji)(ji)運動，沉積在(zai)電(dian)極(ji)(ji)上，而達到粉(fen)塵和氣(qi)體(ti)分離的(de)(de)(de)目的(de)(de)(de)。
