Development of magnetic separation system for removal of ferromagnetic impurity from highly viscous fluid

在处理高粘性流体的工业装置中，清除来自生产线的金属磨损碎屑是必要的。由于介质的高粘度，用一般的分离技术很难从产品中分离出这些杂质，目前还没有建立有效的分离技术。这些杂质可以用磁力从介质中分离出来。本文从实验和仿真两方面对超导磁体和磁滤波器组成的高梯度磁选系统的分离能力进行了研究。研究结果表明，HGMS可以去除高粘性流体中的铁磁性SUS颗粒。

It is necessary to remove the metallic wear debris originating from manufacturing line in industrial plant dealing with highly viscous fluid. These impurities are difficult to separate from products with general separation technique because of high viscosity of the medium, and efficient separation technique is not established yet. These impurities can be separated from the medium with magnetic force. In this study, the separation ability of high gradient magnetic separation system with a superconducting magnet(HGMS) and magnetic filters was examined from experiment and simulation toward the practical use. As the results, the study shows that the removal of ferromagnetic SUS particle in highly viscous fluid is possible by HGMS.
