塔城靜電除塵器廠家

靜電除塵器的工作原理是利用高壓電場(chang)使煙氣發生(sheng)電離(li)，氣流中的粉塵荷電在電場(chang)作用下與氣流分離(li)。負極(ji)由不(bu)同(tong)斷面形狀的金屬導線制成，叫放電電極(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)(de)性能受粉(fen)塵(chen)性質、設備構(gou)造和煙氣(qi)流速等三個因素(su)的(de)(de)(de)(de)影響。粉(fen)塵(chen)的(de)(de)(de)(de)比電(dian)(dian)阻是評價導(dao)電(dian)(dian)性的(de)(de)(de)(de)指標，它對(dui)除塵(chen)效(xiao)率(lv)有直接(jie)的(de)(de)(de)(de)影響。比電(dian)(dian)阻過低，塵(chen)粒難以(yi)保(bao)持(chi)在集(ji)塵(chen)電(dian)(dian)極上(shang)，致使其重返氣(qi)流。比電(dian)(dian)阻過高，到達集(ji)塵(chen)電(dian)(dian)極的(de)(de)(de)(de)塵(chen)粒電(dian)(dian)荷(he)不易放(fang)出，在塵(chen)層之間形成電(dian)(dian)壓(ya)梯度(du)會(hui)產(chan)生(sheng)局部擊穿(chuan)和放(fang)電(dian)(dian)現象。這些情況都會(hui)造成除塵(chen)效(xiao)率(lv)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乃至100kV以上。

工作原理

電(dian)(dian)除塵(chen)器(qi)的(de)(de)基(ji)本原理是利用電(dian)(dian)力捕(bu)集煙氣中的(de)(de)粉(fen)塵(chen)，主要包括(kuo)以下(xia)四個相互有(you)關的(de)(de)物(wu)理過程：（1）氣體的(de)(de)電(dian)(dian)離。（2）粉(fen)塵(chen)的(de)(de)荷(he)電(dian)(dian)。（3）荷(he)電(dian)(dian)粉(fen)塵(chen)向電(dian)(dian)極移動(dong)。（4）荷(he)電(dian)(dian)粉(fen)塵(chen)的(de)(de)捕(bu)集。

荷(he)電(dian)(dian)粉塵(chen)(chen)的(de)捕集過(guo)程：在兩個曲(qu)率(lv)半徑(jing)相(xiang)差較大的(de)金屬陽極(ji)和(he)(he)陰極(ji)上(shang)，通過(guo)高壓直(zhi)流電(dian)(dian)，維持一個足以使氣體電(dian)(dian)離的(de)電(dian)(dian)場(chang)，氣體電(dian)(dian)離后所產生的(de)電(dian)(dian)子：陰離子和(he)(he)陽離子，吸附在通過(guo)電(dian)(dian)場(chang)的(de)粉塵(chen)(chen)上(shang)，使粉塵(chen)(chen)獲得電(dian)(dian)荷(he)。荷(he)電(dian)(dian)極(ji)性不同(tong)的(de)粉塵(chen)(chen)在電(dian)(dian)場(chang)力的(de)作用下，分別(bie)向(xiang)不同(tong)極(ji)性的(de)電(dian)(dian)極(ji)運動，沉積在電(dian)(dian)極(ji)上(shang)，而達到粉塵(chen)(chen)和(he)(he)氣體分離的(de)目的(de)。
