南寧靜電除塵器廠家

靜電除塵器的(de)工作原理是(shi)利(li)用高壓電(dian)場使煙氣(qi)發生電(dian)離，氣(qi)流(liu)(liu)中的(de)粉(fen)塵荷電(dian)在電(dian)場作用下與氣(qi)流(liu)(liu)分離。負極由不同斷面形狀的(de)金屬導線制成，叫放電(dian)電(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)(de)(de)性(xing)能(neng)受粉塵(chen)(chen)性(xing)質、設備構造(zao)和煙(yan)氣流速(su)等(deng)三個因素的(de)(de)(de)影(ying)響。粉塵(chen)(chen)的(de)(de)(de)比(bi)電(dian)(dian)(dian)阻是評價導(dao)電(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它對除塵(chen)(chen)效(xiao)率有(you)直接的(de)(de)(de)影(ying)響。比(bi)電(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以保持在(zai)集塵(chen)(chen)電(dian)(dian)(dian)極(ji)上，致使其重(zhong)返氣流。比(bi)電(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)電(dian)(dian)(dian)極(ji)的(de)(de)(de)塵(chen)(chen)粒電(dian)(dian)(dian)荷不易放出，在(zai)塵(chen)(chen)層之間形成電(dian)(dian)(dian)壓梯(ti)度會產(chan)生(sheng)局部(bu)擊穿和放電(dian)(dian)(dian)現象。這些(xie)情(qing)況都會造(zao)成除塵(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乃至100kV以(yi)上。

工作原理

電(dian)除塵(chen)器的基(ji)本原理是利用電(dian)力捕(bu)集煙氣中的粉(fen)(fen)塵(chen)，主要包括以下四個相(xiang)互有關的物理過程(cheng)：（1）氣體的電(dian)離(li)。（2）粉(fen)(fen)塵(chen)的荷(he)電(dian)。（3）荷(he)電(dian)粉(fen)(fen)塵(chen)向(xiang)電(dian)極移(yi)動。（4）荷(he)電(dian)粉(fen)(fen)塵(chen)的捕(bu)集。

荷(he)電(dian)(dian)(dian)粉塵(chen)的(de)(de)(de)捕集(ji)過(guo)程：在(zai)兩個曲(qu)率半(ban)徑相差較大的(de)(de)(de)金屬(shu)陽(yang)極(ji)(ji)(ji)和陰極(ji)(ji)(ji)上(shang)，通過(guo)高壓直流電(dian)(dian)(dian)，維持一個足以使氣體電(dian)(dian)(dian)離(li)的(de)(de)(de)電(dian)(dian)(dian)場(chang)，氣體電(dian)(dian)(dian)離(li)后所產生的(de)(de)(de)電(dian)(dian)(dian)子：陰離(li)子和陽(yang)離(li)子，吸(xi)附在(zai)通過(guo)電(dian)(dian)(dian)場(chang)的(de)(de)(de)粉塵(chen)上(shang)，使粉塵(chen)獲得電(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)極(ji)(ji)(ji)性不同的(de)(de)(de)粉塵(chen)在(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用下，分別向不同極(ji)(ji)(ji)性的(de)(de)(de)電(dian)(dian)(dian)極(ji)(ji)(ji)運動(dong)，沉積在(zai)電(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，而達到粉塵(chen)和氣體分離(li)的(de)(de)(de)目的(de)(de)(de)。
