酒泉靜電除塵器廠家

靜電除塵器的(de)(de)工作原(yuan)理(li)是利(li)用高壓電(dian)(dian)場(chang)使(shi)煙(yan)氣(qi)發生電(dian)(dian)離，氣(qi)流(liu)中的(de)(de)粉(fen)塵荷電(dian)(dian)在電(dian)(dian)場(chang)作用下與氣(qi)流(liu)分離。負(fu)極(ji)(ji)由不同斷(duan)面形狀(zhuang)的(de)(de)金(jin)屬(shu)導線制成，叫放(fang)電(dian)(dian)電(dian)(dian)極(ji)(ji)。

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)性能受粉塵(chen)(chen)(chen)性質、設(she)備構(gou)造和煙(yan)氣流(liu)速等三個因素的(de)影響。粉塵(chen)(chen)(chen)的(de)比(bi)電(dian)(dian)阻是評(ping)價導(dao)電(dian)(dian)性的(de)指(zhi)標，它對除塵(chen)(chen)(chen)效率(lv)有(you)直接的(de)影響。比(bi)電(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難(nan)以保持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)極上(shang)，致使其重返氣流(liu)。比(bi)電(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)極的(de)塵(chen)(chen)(chen)粒電(dian)(dian)荷不(bu)易放出，在塵(chen)(chen)(chen)層之間(jian)形成電(dian)(dian)壓梯度會產(chan)生局部擊穿和放電(dian)(dian)現象(xiang)。這些情況都會造成除塵(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(dian)壓(ya)需保持40一75kV乃(nai)至100kV以(yi)上。

工作原理

電除塵器的(de)基本原理(li)是(shi)利用電力捕集煙氣(qi)中的(de)粉(fen)(fen)塵，主要包(bao)括以下四(si)個相互有關的(de)物理(li)過程(cheng)：（1）氣(qi)體的(de)電離。（2）粉(fen)(fen)塵的(de)荷(he)電。（3）荷(he)電粉(fen)(fen)塵向電極(ji)移(yi)動(dong)。（4）荷(he)電粉(fen)(fen)塵的(de)捕集。

荷電(dian)(dian)(dian)粉塵(chen)的(de)捕集過(guo)程(cheng)：在(zai)(zai)兩(liang)個曲率半徑相(xiang)差較大(da)的(de)金屬陽(yang)(yang)極(ji)(ji)和(he)陰極(ji)(ji)上，通過(guo)高壓直流電(dian)(dian)(dian)，維持一個足以使氣(qi)體電(dian)(dian)(dian)離的(de)電(dian)(dian)(dian)場(chang)(chang)，氣(qi)體電(dian)(dian)(dian)離后所產生的(de)電(dian)(dian)(dian)子(zi)(zi)：陰離子(zi)(zi)和(he)陽(yang)(yang)離子(zi)(zi)，吸附在(zai)(zai)通過(guo)電(dian)(dian)(dian)場(chang)(chang)的(de)粉塵(chen)上，使粉塵(chen)獲(huo)得電(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)極(ji)(ji)性不同的(de)粉塵(chen)在(zai)(zai)電(dian)(dian)(dian)場(chang)(chang)力(li)的(de)作用下，分(fen)別向不同極(ji)(ji)性的(de)電(dian)(dian)(dian)極(ji)(ji)運動，沉積(ji)在(zai)(zai)電(dian)(dian)(dian)極(ji)(ji)上，而達到粉塵(chen)和(he)氣(qi)體分(fen)離的(de)目的(de)。

基本結構

靜電(dian)(dian)(dian)電(dian)(dian)(dian)除塵器(qi)由兩(liang)大(da)部(bu)分組成：一部(bu)分是(shi)電(dian)(dian)(dian)除塵器(qi)本體(ti)系(xi)統；另一部(bu)分是(shi)提供(gong)(gong)(gong)高壓(ya)(ya)直流電(dian)(dian)(dian)的供(gong)(gong)(gong)電(dian)(dian)(dian)裝置和低壓(ya)(ya)自動(dong)控(kong)(kong)制(zhi)系(xi)統。電(dian)(dian)(dian)除塵器(qi)的結構原理圖(tu)如圖(tu)1所示，高壓(ya)(ya)供(gong)(gong)(gong)電(dian)(dian)(dian)系(xi)統為升壓(ya)(ya)變壓(ya)(ya)器(qi)供(gong)(gong)(gong)電(dian)(dian)(dian)，除塵器(qi)集塵極接(jie)地。低壓(ya)(ya)電(dian)(dian)(dian)控(kong)(kong)制(zhi)系(xi)統用來控(kong)(kong)制(zhi)電(dian)(dian)(dian)磁振打(da)錘、卸灰電(dian)(dian)(dian)極、輸灰電(dian)(dian)(dian)極以及(ji)幾個(ge)部(bu)件(jian)的溫度。
