濟寧靜電除塵器廠家

靜電除塵器的(de)工作原理是(shi)利用(yong)高壓電(dian)(dian)(dian)場使煙氣發生電(dian)(dian)(dian)離，氣流(liu)中的(de)粉(fen)塵荷(he)電(dian)(dian)(dian)在電(dian)(dian)(dian)場作用(yong)下(xia)與氣流(liu)分離。負極(ji)由不同斷面形狀的(de)金屬(shu)導線制(zhi)成，叫放電(dian)(dian)(dian)電(dian)(dian)(dian)極(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(xing)能受粉塵(chen)(chen)性(xing)質、設備構造和(he)煙氣(qi)流速等三個因(yin)素的(de)影響(xiang)。粉塵(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)阻是(shi)評(ping)價(jia)導(dao)電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)指(zhi)標(biao)，它對除塵(chen)(chen)效率(lv)(lv)有直接的(de)影響(xiang)。比電(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)粒難以保(bao)持在集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)上，致(zhi)使其重返氣(qi)流。比電(dian)(dian)(dian)(dian)(dian)阻過高，到達集塵(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)塵(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易放出，在塵(chen)(chen)層之間形成(cheng)電(dian)(dian)(dian)(dian)(dian)壓梯(ti)度(du)會產(chan)生局部擊穿(chuan)和(he)放電(dian)(dian)(dian)(dian)(dian)現象。這些情況都會造成(cheng)除塵(chen)(chen)效率(lv)(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(xing)電壓需保持40一75kV乃至100kV以(yi)上。

工作原理

電(dian)除塵(chen)(chen)(chen)器的(de)基本原理(li)是利用電(dian)力捕集(ji)煙氣(qi)中的(de)粉(fen)塵(chen)(chen)(chen)，主(zhu)要包括以下(xia)四個相互有關的(de)物理(li)過程：（1）氣(qi)體的(de)電(dian)離。（2）粉(fen)塵(chen)(chen)(chen)的(de)荷(he)電(dian)。（3）荷(he)電(dian)粉(fen)塵(chen)(chen)(chen)向電(dian)極移動。（4）荷(he)電(dian)粉(fen)塵(chen)(chen)(chen)的(de)捕集(ji)。

荷電(dian)(dian)(dian)(dian)粉(fen)(fen)塵的(de)捕集過程：在(zai)兩(liang)個曲率半徑相差較大(da)的(de)金屬陽(yang)極和陰極上，通過高壓(ya)直流電(dian)(dian)(dian)(dian)，維持一個足以使氣(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)的(de)電(dian)(dian)(dian)(dian)場，氣(qi)體(ti)電(dian)(dian)(dian)(dian)離(li)后(hou)所產生的(de)電(dian)(dian)(dian)(dian)子(zi)：陰離(li)子(zi)和陽(yang)離(li)子(zi)，吸附在(zai)通過電(dian)(dian)(dian)(dian)場的(de)粉(fen)(fen)塵上，使粉(fen)(fen)塵獲得電(dian)(dian)(dian)(dian)荷。荷電(dian)(dian)(dian)(dian)極性不(bu)(bu)同的(de)粉(fen)(fen)塵在(zai)電(dian)(dian)(dian)(dian)場力的(de)作用下，分別向不(bu)(bu)同極性的(de)電(dian)(dian)(dian)(dian)極運動(dong)，沉積在(zai)電(dian)(dian)(dian)(dian)極上，而達到粉(fen)(fen)塵和氣(qi)體(ti)分離(li)的(de)目的(de)。

基本結構

靜電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)除(chu)塵器(qi)(qi)由(you)兩大(da)部(bu)分組成：一(yi)部(bu)分是(shi)電(dian)(dian)(dian)(dian)除(chu)塵器(qi)(qi)本(ben)體系(xi)統；另一(yi)部(bu)分是(shi)提供(gong)高壓直流(liu)電(dian)(dian)(dian)(dian)的供(gong)電(dian)(dian)(dian)(dian)裝置和低壓自動控(kong)制(zhi)系(xi)統。電(dian)(dian)(dian)(dian)除(chu)塵器(qi)(qi)的結構原理圖(tu)如圖(tu)1所示，高壓供(gong)電(dian)(dian)(dian)(dian)系(xi)統為升壓變(bian)壓器(qi)(qi)供(gong)電(dian)(dian)(dian)(dian)，除(chu)塵器(qi)(qi)集塵極(ji)接地。低壓電(dian)(dian)(dian)(dian)控(kong)制(zhi)系(xi)統用來控(kong)制(zhi)電(dian)(dian)(dian)(dian)磁振(zhen)打錘、卸灰(hui)電(dian)(dian)(dian)(dian)極(ji)、輸灰(hui)電(dian)(dian)(dian)(dian)極(ji)以及(ji)幾個部(bu)件的溫度。
