湘潭靜電除塵器廠家

靜電除塵器的(de)工(gong)作原(yuan)理是利用高壓電(dian)(dian)場使煙氣(qi)發生電(dian)(dian)離(li)，氣(qi)流中的(de)粉塵荷電(dian)(dian)在(zai)電(dian)(dian)場作用下與(yu)氣(qi)流分離(li)。負極由不(bu)同斷面(mian)形(xing)狀的(de)金屬導(dao)線制成，叫放(fang)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(de)性能受(shou)粉塵(chen)性質、設備構造(zao)和煙氣流速等三個(ge)因素(su)的(de)影響。粉塵(chen)的(de)比電(dian)(dian)(dian)阻是評價(jia)導電(dian)(dian)(dian)性的(de)指標，它(ta)對除(chu)塵(chen)效(xiao)(xiao)率有直接的(de)影響。比電(dian)(dian)(dian)阻過低，塵(chen)粒難以(yi)保持在集塵(chen)電(dian)(dian)(dian)極上，致(zhi)使其重返氣流。比電(dian)(dian)(dian)阻過高，到(dao)達集塵(chen)電(dian)(dian)(dian)極的(de)塵(chen)粒電(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)層之間(jian)形(xing)成(cheng)電(dian)(dian)(dian)壓梯度(du)會(hui)產生局部(bu)擊穿和放(fang)電(dian)(dian)(dian)現象。這些情況(kuang)都(dou)會(hui)造(zao)成(cheng)除(chu)塵(chen)效(xiao)(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(xu)保持40一(yi)75kV乃至100kV以上。

工作原理

電(dian)(dian)除塵(chen)器(qi)的(de)(de)基本(ben)原(yuan)理是利用電(dian)(dian)力捕集煙(yan)氣(qi)中的(de)(de)粉(fen)(fen)塵(chen)，主要包括(kuo)以下四個相互有(you)關的(de)(de)物理過程：（1）氣(qi)體(ti)的(de)(de)電(dian)(dian)離。（2）粉(fen)(fen)塵(chen)的(de)(de)荷電(dian)(dian)。（3）荷電(dian)(dian)粉(fen)(fen)塵(chen)向電(dian)(dian)極移(yi)動(dong)。（4）荷電(dian)(dian)粉(fen)(fen)塵(chen)的(de)(de)捕集。

荷電(dian)(dian)(dian)粉(fen)(fen)塵(chen)的(de)(de)(de)捕集過(guo)程：在(zai)兩個曲率半徑相(xiang)差較大的(de)(de)(de)金屬陽(yang)極(ji)(ji)和(he)陰極(ji)(ji)上，通過(guo)高壓(ya)直流電(dian)(dian)(dian)，維持一(yi)個足以使(shi)氣體電(dian)(dian)(dian)離(li)的(de)(de)(de)電(dian)(dian)(dian)場，氣體電(dian)(dian)(dian)離(li)后(hou)所(suo)產生的(de)(de)(de)電(dian)(dian)(dian)子：陰離(li)子和(he)陽(yang)離(li)子，吸附在(zai)通過(guo)電(dian)(dian)(dian)場的(de)(de)(de)粉(fen)(fen)塵(chen)上，使(shi)粉(fen)(fen)塵(chen)獲得(de)電(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)極(ji)(ji)性(xing)不(bu)同(tong)的(de)(de)(de)粉(fen)(fen)塵(chen)在(zai)電(dian)(dian)(dian)場力(li)的(de)(de)(de)作用下，分別(bie)向不(bu)同(tong)極(ji)(ji)性(xing)的(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)運動(dong)，沉積在(zai)電(dian)(dian)(dian)極(ji)(ji)上，而達到粉(fen)(fen)塵(chen)和(he)氣體分離(li)的(de)(de)(de)目的(de)(de)(de)。
