紅河靜電除塵器廠家

靜電除塵器的(de)工作原理是利用(yong)(yong)高壓電(dian)(dian)場(chang)使(shi)煙氣(qi)發生電(dian)(dian)離(li)，氣(qi)流中的(de)粉塵(chen)荷(he)電(dian)(dian)在(zai)電(dian)(dian)場(chang)作用(yong)(yong)下與氣(qi)流分離(li)。負極(ji)由不(bu)同斷面形(xing)狀的(de)金(jin)屬(shu)導線制成，叫放電(dian)(dian)電(dian)(dian)極(ji)。

正極由不同幾何形狀的金屬板制成，叫集塵電極。靜電除塵器廠家的性能受粉塵(chen)性質、設備構造和(he)煙氣流速等三個(ge)因素的影(ying)(ying)響。粉塵(chen)的比電(dian)(dian)阻(zu)是評價導電(dian)(dian)性的指標，它對除(chu)塵(chen)效率有(you)直接的影(ying)(ying)響。比電(dian)(dian)阻(zu)過(guo)低，塵(chen)粒(li)難以保持(chi)在(zai)集(ji)塵(chen)電(dian)(dian)極(ji)上，致使其(qi)重返氣流。比電(dian)(dian)阻(zu)過(guo)高，到達集(ji)塵(chen)電(dian)(dian)極(ji)的塵(chen)粒(li)電(dian)(dian)荷不易放(fang)(fang)出(chu)，在(zai)塵(chen)層之間形成(cheng)電(dian)(dian)壓梯(ti)度會產生(sheng)局(ju)部擊穿(chuan)和(he)放(fang)(fang)電(dian)(dian)現象。這(zhe)些情況都會造成(cheng)除(chu)塵(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，靜電除塵器運行電壓需保(bao)持(chi)40一75kV乃至100kV以上。

工作原理

電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)基本原理是利用(yong)電(dian)(dian)(dian)(dian)力捕集(ji)煙(yan)氣中(zhong)的(de)粉塵(chen)(chen)(chen)，主要包括以(yi)下(xia)四個(ge)相互有關的(de)物理過(guo)程(cheng)：（1）氣體的(de)電(dian)(dian)(dian)(dian)離。（2）粉塵(chen)(chen)(chen)的(de)荷(he)電(dian)(dian)(dian)(dian)。（3）荷(he)電(dian)(dian)(dian)(dian)粉塵(chen)(chen)(chen)向電(dian)(dian)(dian)(dian)極移動。（4）荷(he)電(dian)(dian)(dian)(dian)粉塵(chen)(chen)(chen)的(de)捕集(ji)。

荷(he)電(dian)粉(fen)塵(chen)(chen)的(de)(de)捕(bu)集過程：在(zai)(zai)兩個(ge)曲率半徑相(xiang)差較(jiao)大的(de)(de)金(jin)屬陽(yang)(yang)極(ji)和陰極(ji)上(shang)，通(tong)過高壓直(zhi)流電(dian)，維持一(yi)個(ge)足以(yi)使氣體(ti)電(dian)離的(de)(de)電(dian)場，氣體(ti)電(dian)離后(hou)所產生的(de)(de)電(dian)子(zi)(zi)：陰離子(zi)(zi)和陽(yang)(yang)離子(zi)(zi)，吸附(fu)在(zai)(zai)通(tong)過電(dian)場的(de)(de)粉(fen)塵(chen)(chen)上(shang)，使粉(fen)塵(chen)(chen)獲得電(dian)荷(he)。荷(he)電(dian)極(ji)性(xing)不(bu)同的(de)(de)粉(fen)塵(chen)(chen)在(zai)(zai)電(dian)場力的(de)(de)作用下，分(fen)別向不(bu)同極(ji)性(xing)的(de)(de)電(dian)極(ji)運動，沉積在(zai)(zai)電(dian)極(ji)上(shang)，而達到粉(fen)塵(chen)(chen)和氣體(ti)分(fen)離的(de)(de)目的(de)(de)。

基本結構

靜電(dian)(dian)(dian)電(dian)(dian)(dian)除(chu)塵器(qi)(qi)由兩(liang)大部分組成：一部分是(shi)電(dian)(dian)(dian)除(chu)塵器(qi)(qi)本體系統；另一部分是(shi)提供(gong)(gong)高壓(ya)(ya)直流電(dian)(dian)(dian)的供(gong)(gong)電(dian)(dian)(dian)裝置(zhi)和低(di)壓(ya)(ya)自動(dong)控制系統。電(dian)(dian)(dian)除(chu)塵器(qi)(qi)的結構原理圖(tu)如圖(tu)1所(suo)示，高壓(ya)(ya)供(gong)(gong)電(dian)(dian)(dian)系統為(wei)升壓(ya)(ya)變壓(ya)(ya)器(qi)(qi)供(gong)(gong)電(dian)(dian)(dian)，除(chu)塵器(qi)(qi)集塵極(ji)接地。低(di)壓(ya)(ya)電(dian)(dian)(dian)控制系統用(yong)來控制電(dian)(dian)(dian)磁振打(da)錘、卸(xie)灰電(dian)(dian)(dian)極(ji)、輸灰電(dian)(dian)(dian)極(ji)以及幾(ji)個部件的溫度。
