黑龍江靜電除塵器廠家

靜電除塵器的工作原理是利用(yong)高壓電(dian)場(chang)使煙氣(qi)發生電(dian)離，氣(qi)流(liu)中的粉塵(chen)荷(he)電(dian)在電(dian)場(chang)作用(yong)下與氣(qi)流(liu)分離。負極由不同斷面形狀的金(jin)屬(shu)導線制成(cheng)，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)性(xing)能(neng)受粉(fen)塵(chen)(chen)(chen)性(xing)質、設(she)備構造和煙氣(qi)流速等三個因素的(de)(de)影響。粉(fen)塵(chen)(chen)(chen)的(de)(de)比(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)是評(ping)價導(dao)電(dian)(dian)(dian)(dian)性(xing)的(de)(de)指標，它對(dui)除(chu)(chu)塵(chen)(chen)(chen)效率有(you)直接(jie)的(de)(de)影響。比(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)過低，塵(chen)(chen)(chen)粒難以保持在集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極上(shang)，致使其重返(fan)氣(qi)流。比(bi)電(dian)(dian)(dian)(dian)阻(zu)(zu)過高，到(dao)達集塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)極的(de)(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)(chen)層之間形成電(dian)(dian)(dian)(dian)壓(ya)梯度(du)會產(chan)生(sheng)局部擊穿和放電(dian)(dian)(dian)(dian)現(xian)象。這(zhe)些情況都會造成除(chu)(chu)塵(chen)(chen)(chen)效率下降。

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(ya)需保(bao)持(chi)40一75kV乃至100kV以(yi)上。

工作原理

電除塵器(qi)的(de)(de)基本(ben)原理是(shi)利用電力捕集(ji)煙(yan)氣中的(de)(de)粉塵，主要包(bao)括(kuo)以下四個(ge)相互有關的(de)(de)物理過(guo)程：（1）氣體的(de)(de)電離。（2）粉塵的(de)(de)荷電。（3）荷電粉塵向電極移動(dong)。（4）荷電粉塵的(de)(de)捕集(ji)。

荷電(dian)(dian)(dian)(dian)粉(fen)(fen)塵(chen)(chen)的(de)(de)捕集過程(cheng)：在兩(liang)個(ge)曲率半徑相(xiang)差(cha)較大的(de)(de)金屬(shu)陽(yang)極(ji)(ji)和陰極(ji)(ji)上，通(tong)過高(gao)壓直流電(dian)(dian)(dian)(dian)，維(wei)持(chi)一個(ge)足以使氣(qi)體電(dian)(dian)(dian)(dian)離(li)的(de)(de)電(dian)(dian)(dian)(dian)場(chang)，氣(qi)體電(dian)(dian)(dian)(dian)離(li)后所產生的(de)(de)電(dian)(dian)(dian)(dian)子(zi)：陰離(li)子(zi)和陽(yang)離(li)子(zi)，吸附在通(tong)過電(dian)(dian)(dian)(dian)場(chang)的(de)(de)粉(fen)(fen)塵(chen)(chen)上，使粉(fen)(fen)塵(chen)(chen)獲(huo)得電(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)極(ji)(ji)性(xing)不同(tong)的(de)(de)粉(fen)(fen)塵(chen)(chen)在電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)作用下，分別向不同(tong)極(ji)(ji)性(xing)的(de)(de)電(dian)(dian)(dian)(dian)極(ji)(ji)運動，沉積在電(dian)(dian)(dian)(dian)極(ji)(ji)上，而(er)達到粉(fen)(fen)塵(chen)(chen)和氣(qi)體分離(li)的(de)(de)目的(de)(de)。

基本結構

靜(jing)電(dian)(dian)電(dian)(dian)除(chu)塵器由兩(liang)大部分組成：一部分是(shi)電(dian)(dian)除(chu)塵器本體系(xi)統；另一部分是(shi)提供(gong)(gong)高壓(ya)(ya)直流電(dian)(dian)的(de)供(gong)(gong)電(dian)(dian)裝(zhuang)置和(he)低壓(ya)(ya)自動控制(zhi)系(xi)統。電(dian)(dian)除(chu)塵器的(de)結構原理(li)圖(tu)如圖(tu)1所示，高壓(ya)(ya)供(gong)(gong)電(dian)(dian)系(xi)統為(wei)升(sheng)壓(ya)(ya)變壓(ya)(ya)器供(gong)(gong)電(dian)(dian)，除(chu)塵器集塵極接地(di)。低壓(ya)(ya)電(dian)(dian)控制(zhi)系(xi)統用來控制(zhi)電(dian)(dian)磁(ci)振(zhen)打錘、卸灰電(dian)(dian)極、輸灰電(dian)(dian)極以及幾個部件的(de)溫度。
