摘 要: 基于“磁筛”理论,利用ANSYS有限元分析软件模拟分析“空竹”形磁场空间层叠磁体阵列结构中的磁场分布。模拟结果表明:“空竹”形磁场空间可以有效增加“磁筛”的氧气分子拦截能力;层叠磁体阵列结构可以在增强每个流道“磁筛”作用的同时有效提高气量处理的能力;导磁轭铁的引入,不仅可以有效提高流道内的磁场强度,从而增强“磁筛”对氧气分子的拦截能力,还可以消除层叠磁体阵列中各个流道之间的氧气分子拦截能力的差异。
关 键 词: 节能技术;氧氮分离;梯度磁场;磁筛;氧气分子拦截能力;层叠磁体阵列结构

Abstract: Based on the concept of “magnetic-sieve”, the magnetic field distribution in the “Diabolo-shaped” magnetic field space was simulated by ANSYS finite element software. The results showed that the intercepting effect on oxygen molecules was enhanced in the “Diabolo-shaped” magnetic field space. Multi-channel cascading magnets’array not only enhanced the “magnetic-sieve” effect in each channel, but also improved the ability of air flow processing effectively. By introducing and magnetic yoke, the central magnetic flux density was increased, consequently, the intercepting effect on oxygen molecules by “magnetic-sieve” was enhanced, meanwhile, the difference of intercepting effect on oxygen molecules between each channel in multi-channel cascading magnets’array was eliminated.
Key words: energy-saving technology; oxygen and nitrogen separation; gradient magnetic field; magnetic-sieve; intercepting effect on the oxygen molecules; multi-channel cascading magnets’ array
