石河子靜電除塵器廠家

靜電除塵器的工作(zuo)原理是利用高(gao)壓(ya)電(dian)(dian)(dian)場(chang)(chang)使煙氣發生電(dian)(dian)(dian)離，氣流中(zhong)的粉塵(chen)荷電(dian)(dian)(dian)在電(dian)(dian)(dian)場(chang)(chang)作(zuo)用下與氣流分離。負極由不(bu)同(tong)斷面(mian)形狀的金屬導線制成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的性能受(shou)粉塵(chen)(chen)(chen)性質(zhi)、設(she)備構造(zao)和煙氣流速等三個(ge)因素的影響。粉塵(chen)(chen)(chen)的比電(dian)(dian)(dian)阻(zu)是(shi)評價導(dao)電(dian)(dian)(dian)性的指標，它對(dui)除塵(chen)(chen)(chen)效率(lv)有直接的影響。比電(dian)(dian)(dian)阻(zu)過(guo)低，塵(chen)(chen)(chen)粒(li)難以保持在集塵(chen)(chen)(chen)電(dian)(dian)(dian)極上(shang)，致使其重返氣流。比電(dian)(dian)(dian)阻(zu)過(guo)高，到達集塵(chen)(chen)(chen)電(dian)(dian)(dian)極的塵(chen)(chen)(chen)粒(li)電(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)(chen)層之間形(xing)成電(dian)(dian)(dian)壓梯度會產生局部擊穿和放電(dian)(dian)(dian)現象。這些情況都會造(zao)成除塵(chen)(chen)(chen)效率(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(ya)需保持40一75kV乃(nai)至(zhi)100kV以(yi)上。

工作原理

電(dian)(dian)除塵(chen)(chen)(chen)器的(de)(de)基本原(yuan)理是利(li)用電(dian)(dian)力捕(bu)集(ji)煙(yan)氣(qi)中的(de)(de)粉塵(chen)(chen)(chen)，主要包括以下四個相互(hu)有關的(de)(de)物理過程：（1）氣(qi)體的(de)(de)電(dian)(dian)離。（2）粉塵(chen)(chen)(chen)的(de)(de)荷電(dian)(dian)。（3）荷電(dian)(dian)粉塵(chen)(chen)(chen)向電(dian)(dian)極移(yi)動。（4）荷電(dian)(dian)粉塵(chen)(chen)(chen)的(de)(de)捕(bu)集(ji)。

荷(he)電(dian)(dian)(dian)(dian)粉(fen)塵(chen)的(de)(de)(de)(de)捕集過程：在(zai)兩個(ge)曲率半徑相(xiang)差較大的(de)(de)(de)(de)金(jin)屬陽極(ji)和陰(yin)極(ji)上，通過高壓(ya)直流電(dian)(dian)(dian)(dian)，維持一個(ge)足以(yi)使氣(qi)體電(dian)(dian)(dian)(dian)離的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)場，氣(qi)體電(dian)(dian)(dian)(dian)離后(hou)所產生的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)：陰(yin)離子(zi)和陽離子(zi)，吸(xi)附在(zai)通過電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)上，使粉(fen)塵(chen)獲得電(dian)(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)(dian)極(ji)性不(bu)同(tong)的(de)(de)(de)(de)粉(fen)塵(chen)在(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作用下，分別向不(bu)同(tong)極(ji)性的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)運動，沉積在(zai)電(dian)(dian)(dian)(dian)極(ji)上，而達(da)到(dao)粉(fen)塵(chen)和氣(qi)體分離的(de)(de)(de)(de)目的(de)(de)(de)(de)。
