東方靜電除塵器廠家

靜電除塵器的(de)工作(zuo)原理是利用(yong)高壓電(dian)場(chang)使煙氣(qi)發生(sheng)電(dian)離(li)，氣(qi)流(liu)中的(de)粉(fen)塵荷(he)電(dian)在(zai)電(dian)場(chang)作(zuo)用(yong)下與氣(qi)流(liu)分離(li)。負極由不同斷面(mian)形狀的(de)金屬導線制成，叫(jiao)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)性(xing)能受粉(fen)塵(chen)(chen)性(xing)質、設備構(gou)造和煙氣流(liu)速等三個因素的(de)影響。粉(fen)塵(chen)(chen)的(de)比(bi)(bi)電(dian)阻(zu)是評價導電(dian)性(xing)的(de)指(zhi)標，它對(dui)除塵(chen)(chen)效(xiao)率(lv)有直接的(de)影響。比(bi)(bi)電(dian)阻(zu)過(guo)低，塵(chen)(chen)粒難以保持(chi)在集塵(chen)(chen)電(dian)極上，致使其重返氣流(liu)。比(bi)(bi)電(dian)阻(zu)過(guo)高，到達(da)集塵(chen)(chen)電(dian)極的(de)塵(chen)(chen)粒電(dian)荷不易放(fang)出，在塵(chen)(chen)層(ceng)之間形成(cheng)電(dian)壓梯度會產(chan)生局部擊穿和放(fang)電(dian)現象(xiang)。這些(xie)情況都會造成(cheng)除塵(chen)(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(yun)行電壓需保持40一(yi)75kV乃至100kV以上。

工作原理

電除塵(chen)器的(de)(de)基本原理是利用電力捕(bu)集煙氣(qi)中的(de)(de)粉(fen)(fen)塵(chen)，主要包括以下四個(ge)相(xiang)互(hu)有關的(de)(de)物(wu)理過程：（1）氣(qi)體的(de)(de)電離。（2）粉(fen)(fen)塵(chen)的(de)(de)荷電。（3）荷電粉(fen)(fen)塵(chen)向電極(ji)移動(dong)。（4）荷電粉(fen)(fen)塵(chen)的(de)(de)捕(bu)集。

荷電(dian)(dian)(dian)(dian)(dian)粉(fen)(fen)塵的(de)(de)(de)捕集過(guo)程：在兩個(ge)(ge)曲(qu)率(lv)半徑(jing)相(xiang)差較大的(de)(de)(de)金(jin)屬陽(yang)極和(he)陰(yin)極上(shang)，通過(guo)高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)，維(wei)持一個(ge)(ge)足以使氣體電(dian)(dian)(dian)(dian)(dian)離(li)(li)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)場，氣體電(dian)(dian)(dian)(dian)(dian)離(li)(li)后(hou)所(suo)產(chan)生的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子：陰(yin)離(li)(li)子和(he)陽(yang)離(li)(li)子，吸附(fu)在通過(guo)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)粉(fen)(fen)塵上(shang)，使粉(fen)(fen)塵獲得(de)電(dian)(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)(dian)極性不(bu)(bu)同的(de)(de)(de)粉(fen)(fen)塵在電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用下，分別向不(bu)(bu)同極性的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極運(yun)動，沉積在電(dian)(dian)(dian)(dian)(dian)極上(shang)，而達到粉(fen)(fen)塵和(he)氣體分離(li)(li)的(de)(de)(de)目的(de)(de)(de)。
