摘要
摘要二氧化硅是lcd和oled电子工业中必不可少的材料，对其纯度要求很高。本研究试图利用CFD模拟方法寻找含铁化合物硅砂磁选机的最佳设计方案。制备了三种磁选方案，并对其效率进行了检验。结果表明，二氧化硅颗粒与磁性发射体表面的充分接触改善了磁选效果。此外，sio2的损失率和fe2o3的去除率与颗粒大小、流速和磁通密度密切相关。此外，对于粒径为10微米(100万分之微米)、流速为0.2米/秒的颗粒，磁分离也非常有效。通讯作者:Sang Bum Kim (Korea Institute of Industrial Technology)电话:+82-10-8978-9677电子邮件:sbkim@kitech.re.krReceived 2015.09.04接收于2016.01.05修改于2015.9.22发布于2016.01.31
Design simulation of magnetic separator for purification of silica sand
Abstract Silica is an essential material in the electronics industries of LCDs and OLEDs, which particularly requirehigh purity. This study attempted to find the optimal design of a magnetic separator for silica sand containing iron compounds using CFD simulation. Three designs of magnetic separation were prepared and their efficiency was examined. As a result of the evaluation, the sufficient contact of particulate silica with the surface of magnetic emitters improved the magnetic separation effects. In addition, the loss of SiO 2 and the removal rate of Fe 2 O 3 depended stronglyon the particle size, flow rate and magnetic flux density. In addition, magnetic separation is quite effective for a particlesize of 10 ㎛ with a 0.2 m/s flow rate.
