舟山靜電除塵器廠家

靜電除塵器的工作原理是利用高(gao)壓電(dian)(dian)場使煙氣發生電(dian)(dian)離，氣流中(zhong)的粉塵(chen)荷電(dian)(dian)在電(dian)(dian)場作用下與氣流分(fen)離。負(fu)極由不同斷面形(xing)狀的金屬導線制成，叫放電(dian)(dian)電(dian)(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)能受粉塵(chen)(chen)性(xing)質、設(she)備(bei)構(gou)造(zao)和煙氣流速等三個因素的影響(xiang)(xiang)。粉塵(chen)(chen)的比(bi)電(dian)(dian)(dian)阻是(shi)評價導電(dian)(dian)(dian)性(xing)的指(zhi)標，它對除(chu)塵(chen)(chen)效率有直(zhi)接的影響(xiang)(xiang)。比(bi)電(dian)(dian)(dian)阻過(guo)低，塵(chen)(chen)粒(li)難(nan)以保持(chi)在(zai)集塵(chen)(chen)電(dian)(dian)(dian)極上，致使其重(zhong)返氣流。比(bi)電(dian)(dian)(dian)阻過(guo)高，到達集塵(chen)(chen)電(dian)(dian)(dian)極的塵(chen)(chen)粒(li)電(dian)(dian)(dian)荷不易(yi)放(fang)出，在(zai)塵(chen)(chen)層(ceng)之間形成(cheng)電(dian)(dian)(dian)壓梯(ti)度會產生局部擊(ji)穿(chuan)和放(fang)電(dian)(dian)(dian)現象。這些情況都會造(zao)成(cheng)除(chu)塵(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(yun)行電壓需(xu)保持40一75kV乃至(zhi)100kV以上。

工作原理

電(dian)除塵(chen)(chen)器的(de)(de)基本原理(li)(li)是(shi)利用電(dian)力捕集(ji)煙氣中的(de)(de)粉(fen)塵(chen)(chen)，主要包括(kuo)以下(xia)四個相互有關的(de)(de)物理(li)(li)過程：（1）氣體的(de)(de)電(dian)離。（2）粉(fen)塵(chen)(chen)的(de)(de)荷(he)(he)電(dian)。（3）荷(he)(he)電(dian)粉(fen)塵(chen)(chen)向電(dian)極移動(dong)。（4）荷(he)(he)電(dian)粉(fen)塵(chen)(chen)的(de)(de)捕集(ji)。

荷(he)電(dian)(dian)(dian)(dian)粉塵(chen)(chen)的(de)(de)(de)(de)捕集過程：在兩(liang)個曲率半徑相差較大的(de)(de)(de)(de)金(jin)屬(shu)陽極(ji)和(he)(he)(he)陰極(ji)上，通過高壓直流電(dian)(dian)(dian)(dian)，維持一個足以使氣體(ti)(ti)電(dian)(dian)(dian)(dian)離(li)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)場，氣體(ti)(ti)電(dian)(dian)(dian)(dian)離(li)后所產生的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)：陰離(li)子(zi)和(he)(he)(he)陽離(li)子(zi)，吸附在通過電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉塵(chen)(chen)上，使粉塵(chen)(chen)獲得電(dian)(dian)(dian)(dian)荷(he)。荷(he)電(dian)(dian)(dian)(dian)極(ji)性(xing)不同的(de)(de)(de)(de)粉塵(chen)(chen)在電(dian)(dian)(dian)(dian)場力的(de)(de)(de)(de)作用下，分別(bie)向不同極(ji)性(xing)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極(ji)運動(dong)，沉積在電(dian)(dian)(dian)(dian)極(ji)上，而達到粉塵(chen)(chen)和(he)(he)(he)氣體(ti)(ti)分離(li)的(de)(de)(de)(de)目的(de)(de)(de)(de)。

基本結構

靜電(dian)電(dian)除(chu)(chu)塵(chen)(chen)器由兩大部分(fen)(fen)組成：一部分(fen)(fen)是(shi)電(dian)除(chu)(chu)塵(chen)(chen)器本體(ti)系統；另一部分(fen)(fen)是(shi)提供(gong)高(gao)壓(ya)(ya)(ya)直流(liu)電(dian)的(de)供(gong)電(dian)裝置和低(di)壓(ya)(ya)(ya)自動控制系統。電(dian)除(chu)(chu)塵(chen)(chen)器的(de)結構(gou)原理圖如圖1所示，高(gao)壓(ya)(ya)(ya)供(gong)電(dian)系統為(wei)升壓(ya)(ya)(ya)變(bian)壓(ya)(ya)(ya)器供(gong)電(dian)，除(chu)(chu)塵(chen)(chen)器集塵(chen)(chen)極接地。低(di)壓(ya)(ya)(ya)電(dian)控制系統用(yong)來控制電(dian)磁振打錘(chui)、卸灰電(dian)極、輸(shu)灰電(dian)極以及(ji)幾個(ge)部件的(de)溫度。
