雞西靜電除塵器廠家

靜電除塵器的(de)工(gong)作原理是利用(yong)高壓電(dian)場(chang)使煙(yan)氣發(fa)生電(dian)離，氣流中的(de)粉(fen)塵荷電(dian)在電(dian)場(chang)作用(yong)下(xia)與氣流分(fen)離。負極由不同(tong)斷面形狀的(de)金屬導線制成，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(xing)能受(shou)粉(fen)塵性(xing)質、設備構(gou)造和(he)煙氣(qi)流(liu)速等(deng)三個因素的影響。粉(fen)塵的比(bi)電(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)性(xing)的指標，它對除塵效(xiao)率有直接的影響。比(bi)電(dian)(dian)(dian)阻過(guo)低，塵粒難以保持在集塵電(dian)(dian)(dian)極上(shang)，致使其重返(fan)氣(qi)流(liu)。比(bi)電(dian)(dian)(dian)阻過(guo)高，到達集塵電(dian)(dian)(dian)極的塵粒電(dian)(dian)(dian)荷不易放出，在塵層之間形(xing)成電(dian)(dian)(dian)壓梯度(du)會(hui)產生局(ju)部(bu)擊穿和(he)放電(dian)(dian)(dian)現象。這些情況都會(hui)造成除塵效(xiao)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(dian)壓需保持40一(yi)75kV乃至100kV以上。

工作原理

電(dian)除塵(chen)(chen)器的基本原(yuan)理(li)是利用電(dian)力捕(bu)(bu)集煙氣(qi)中的粉塵(chen)(chen)，主要包括以下四(si)個(ge)相互有關的物理(li)過程：（1）氣(qi)體的電(dian)離。（2）粉塵(chen)(chen)的荷(he)電(dian)。（3）荷(he)電(dian)粉塵(chen)(chen)向電(dian)極移(yi)動。（4）荷(he)電(dian)粉塵(chen)(chen)的捕(bu)(bu)集。

荷電(dian)(dian)粉塵(chen)(chen)的(de)捕集過(guo)程(cheng)：在(zai)兩個曲率半徑相差較(jiao)大的(de)金屬陽極(ji)(ji)和(he)陰(yin)極(ji)(ji)上(shang)，通過(guo)高壓直流電(dian)(dian)，維持一個足以使(shi)氣體電(dian)(dian)離(li)的(de)電(dian)(dian)場，氣體電(dian)(dian)離(li)后所(suo)產生的(de)電(dian)(dian)子(zi)：陰(yin)離(li)子(zi)和(he)陽離(li)子(zi)，吸附在(zai)通過(guo)電(dian)(dian)場的(de)粉塵(chen)(chen)上(shang)，使(shi)粉塵(chen)(chen)獲(huo)得電(dian)(dian)荷。荷電(dian)(dian)極(ji)(ji)性不同的(de)粉塵(chen)(chen)在(zai)電(dian)(dian)場力的(de)作用下，分別向不同極(ji)(ji)性的(de)電(dian)(dian)極(ji)(ji)運動(dong)，沉積在(zai)電(dian)(dian)極(ji)(ji)上(shang)，而達(da)到粉塵(chen)(chen)和(he)氣體分離(li)的(de)目的(de)。

基本結構

靜電(dian)(dian)(dian)電(dian)(dian)(dian)除(chu)塵(chen)器由兩(liang)大(da)部(bu)分(fen)組成：一部(bu)分(fen)是電(dian)(dian)(dian)除(chu)塵(chen)器本體系(xi)統(tong)；另一部(bu)分(fen)是提(ti)供高壓(ya)(ya)直流電(dian)(dian)(dian)的供電(dian)(dian)(dian)裝(zhuang)置和低壓(ya)(ya)自動(dong)控(kong)制(zhi)(zhi)系(xi)統(tong)。電(dian)(dian)(dian)除(chu)塵(chen)器的結構(gou)原(yuan)理圖如圖1所示，高壓(ya)(ya)供電(dian)(dian)(dian)系(xi)統(tong)為升壓(ya)(ya)變壓(ya)(ya)器供電(dian)(dian)(dian)，除(chu)塵(chen)器集塵(chen)極(ji)接地(di)。低壓(ya)(ya)電(dian)(dian)(dian)控(kong)制(zhi)(zhi)系(xi)統(tong)用來控(kong)制(zhi)(zhi)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)以及幾個部(bu)件的溫度。
