徐州靜電除塵器廠家

靜電除塵器的工作原(yuan)理是利用高壓(ya)電(dian)(dian)(dian)(dian)場使煙氣(qi)(qi)發生電(dian)(dian)(dian)(dian)離(li)，氣(qi)(qi)流(liu)中的粉塵荷電(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)場作用下與氣(qi)(qi)流(liu)分離(li)。負極由(you)不同斷面形狀(zhuang)的金屬導線制成，叫放電(dian)(dian)(dian)(dian)電(dian)(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(de)性能(neng)受粉塵(chen)性質、設備構造和(he)煙氣流速等(deng)三個因素的(de)影響。粉塵(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)是評價導電(dian)(dian)(dian)(dian)(dian)性的(de)指標，它對除塵(chen)效率(lv)有直(zhi)接的(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)粒難以(yi)保持在集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極上(shang)，致使(shi)其(qi)重返(fan)氣流。比電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過高，到(dao)達(da)集(ji)塵(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)塵(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)層(ceng)之間形成電(dian)(dian)(dian)(dian)(dian)壓梯度(du)會產生(sheng)局(ju)部擊穿(chuan)和(he)放(fang)電(dian)(dian)(dian)(dian)(dian)現象(xiang)。這(zhe)些情況都會造成除塵(chen)效率(lv)下降(jiang)。

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(dian)壓需保持40一75kV乃至100kV以上(shang)。

工作原理

電(dian)除塵(chen)器的(de)(de)基本原理是(shi)利用電(dian)力捕(bu)集煙(yan)氣中的(de)(de)粉(fen)塵(chen)，主要包括以下四個相(xiang)互(hu)有(you)關的(de)(de)物理過程：（1）氣體的(de)(de)電(dian)離。（2）粉(fen)塵(chen)的(de)(de)荷(he)電(dian)。（3）荷(he)電(dian)粉(fen)塵(chen)向電(dian)極移動(dong)。（4）荷(he)電(dian)粉(fen)塵(chen)的(de)(de)捕(bu)集。

荷電(dian)(dian)粉塵(chen)(chen)的(de)(de)捕集過程：在(zai)(zai)兩個曲(qu)率半徑相差較(jiao)大的(de)(de)金屬陽極和(he)(he)(he)陰極上，通過高壓直流電(dian)(dian)，維持一個足以(yi)使(shi)氣(qi)體(ti)電(dian)(dian)離(li)的(de)(de)電(dian)(dian)場，氣(qi)體(ti)電(dian)(dian)離(li)后所產(chan)生(sheng)的(de)(de)電(dian)(dian)子(zi)：陰離(li)子(zi)和(he)(he)(he)陽離(li)子(zi)，吸附(fu)在(zai)(zai)通過電(dian)(dian)場的(de)(de)粉塵(chen)(chen)上，使(shi)粉塵(chen)(chen)獲得電(dian)(dian)荷。荷電(dian)(dian)極性不同的(de)(de)粉塵(chen)(chen)在(zai)(zai)電(dian)(dian)場力的(de)(de)作用下，分(fen)別向不同極性的(de)(de)電(dian)(dian)極運動，沉積在(zai)(zai)電(dian)(dian)極上，而達到粉塵(chen)(chen)和(he)(he)(he)氣(qi)體(ti)分(fen)離(li)的(de)(de)目的(de)(de)。

基本結構

靜電(dian)(dian)電(dian)(dian)除塵(chen)器(qi)由(you)兩大部分(fen)組(zu)成：一部分(fen)是電(dian)(dian)除塵(chen)器(qi)本體系統(tong)；另一部分(fen)是提(ti)供高壓(ya)(ya)直流電(dian)(dian)的(de)供電(dian)(dian)裝置(zhi)和低(di)壓(ya)(ya)自動控制系統(tong)。電(dian)(dian)除塵(chen)器(qi)的(de)結構原理圖如圖1所示，高壓(ya)(ya)供電(dian)(dian)系統(tong)為(wei)升壓(ya)(ya)變壓(ya)(ya)器(qi)供電(dian)(dian)，除塵(chen)器(qi)集塵(chen)極(ji)接地。低(di)壓(ya)(ya)電(dian)(dian)控制系統(tong)用來控制電(dian)(dian)磁(ci)振(zhen)打錘、卸灰電(dian)(dian)極(ji)、輸(shu)灰電(dian)(dian)極(ji)以及幾個部件的(de)溫度。
