孝感靜電除塵器廠家

靜電除塵器的(de)工(gong)作原理是利用高壓電(dian)場使煙氣發生電(dian)離，氣流(liu)中的(de)粉(fen)塵(chen)荷電(dian)在電(dian)場作用下與氣流(liu)分離。負(fu)極由不同斷面形狀的(de)金屬導(dao)線制成，叫放(fang)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。靜電除塵器廠家的性能受(shou)粉塵(chen)(chen)性質、設備構造(zao)和煙氣流速等三個因素的影響(xiang)。粉塵(chen)(chen)的比(bi)電(dian)阻是評價(jia)導(dao)電(dian)性的指標，它對除(chu)塵(chen)(chen)效率(lv)有直(zhi)接(jie)的影響(xiang)。比(bi)電(dian)阻過低(di)，塵(chen)(chen)粒(li)難(nan)以(yi)保(bao)持在(zai)集塵(chen)(chen)電(dian)極上，致使其重返氣流。比(bi)電(dian)阻過高，到達集塵(chen)(chen)電(dian)極的塵(chen)(chen)粒(li)電(dian)荷不易放出，在(zai)塵(chen)(chen)層之間形成電(dian)壓梯度會(hui)產生(sheng)局部擊穿(chuan)和放電(dian)現象(xiang)。這些情況都會(hui)造(zao)成除(chu)塵(chen)(chen)效率(lv)下(xia)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(yun)行電壓需保持40一(yi)75kV乃至100kV以上。

工作原理

電(dian)(dian)除塵器(qi)的(de)(de)基本原理(li)是利用(yong)電(dian)(dian)力捕集(ji)煙氣(qi)(qi)中的(de)(de)粉(fen)塵，主要(yao)包括以下四個相(xiang)互有關的(de)(de)物理(li)過程(cheng)：（1）氣(qi)(qi)體(ti)的(de)(de)電(dian)(dian)離(li)。（2）粉(fen)塵的(de)(de)荷電(dian)(dian)。（3）荷電(dian)(dian)粉(fen)塵向電(dian)(dian)極移動。（4）荷電(dian)(dian)粉(fen)塵的(de)(de)捕集(ji)。

荷(he)電(dian)(dian)(dian)粉(fen)塵(chen)(chen)的(de)(de)(de)捕集過(guo)程：在兩個(ge)曲率半(ban)徑相差較大的(de)(de)(de)金(jin)屬(shu)陽極和陰(yin)極上(shang)(shang)，通過(guo)高壓(ya)直流電(dian)(dian)(dian)，維持一個(ge)足以使氣(qi)體電(dian)(dian)(dian)離(li)(li)的(de)(de)(de)電(dian)(dian)(dian)場，氣(qi)體電(dian)(dian)(dian)離(li)(li)后所產生的(de)(de)(de)電(dian)(dian)(dian)子(zi)：陰(yin)離(li)(li)子(zi)和陽離(li)(li)子(zi)，吸附在通過(guo)電(dian)(dian)(dian)場的(de)(de)(de)粉(fen)塵(chen)(chen)上(shang)(shang)，使粉(fen)塵(chen)(chen)獲得電(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)極性不同(tong)的(de)(de)(de)粉(fen)塵(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)(de)作(zuo)用(yong)下，分別向不同(tong)極性的(de)(de)(de)電(dian)(dian)(dian)極運動，沉積在電(dian)(dian)(dian)極上(shang)(shang)，而達到粉(fen)塵(chen)(chen)和氣(qi)體分離(li)(li)的(de)(de)(de)目的(de)(de)(de)。

基本結構

靜電(dian)(dian)(dian)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)由(you)兩大部(bu)分組成：一(yi)部(bu)分是電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)本體系(xi)統；另一(yi)部(bu)分是提供(gong)高(gao)壓(ya)(ya)直流電(dian)(dian)(dian)的供(gong)電(dian)(dian)(dian)裝置和(he)低(di)壓(ya)(ya)自動控(kong)制系(xi)統。電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)的結(jie)構原(yuan)理圖如圖1所示，高(gao)壓(ya)(ya)供(gong)電(dian)(dian)(dian)系(xi)統為升壓(ya)(ya)變壓(ya)(ya)器(qi)供(gong)電(dian)(dian)(dian)，除(chu)塵(chen)(chen)器(qi)集(ji)塵(chen)(chen)極(ji)接地(di)。低(di)壓(ya)(ya)電(dian)(dian)(dian)控(kong)制系(xi)統用來控(kong)制電(dian)(dian)(dian)磁振打錘、卸灰(hui)電(dian)(dian)(dian)極(ji)、輸灰(hui)電(dian)(dian)(dian)極(ji)以及幾個(ge)部(bu)件的溫度。
