摘要

本工作对现有的磁性纤维捕获铁基细颗粒的方法进行了改进,并进一步确定了纤维过滤材料的编织方法。当沿X、Y和z轴施加均匀磁场时,磁性纤维周围会形成不同的磁场组合,从而改变正交磁性纤维之间的相互作用。因此,采用计算流体动力学离散相模型(CFD-DPM)和特殊的磁力自定义函数(UDF)对正交磁纤维在三种构型下的粒子捕获过程进行了比较。结果表明,正交磁纤维之间的相互作用可以抑制或促进相邻磁纤维对铁基细颗粒的捕获。在工业生产中,磁性滤料适用于磁性纤维与传统纤维交替使用的织造方法。当沿x轴方向施加均匀磁场时,这种编织方法使正交磁性纤维的捕获性能最好。此外,还应考虑磁特性、流特性和磁场的组合顺序。该研究为科学研究人员开发新型高效纤维过滤器以减少颗粒污染物的排放提供了新的见解。

The influence of interaction between orthogonal magnetic fibers on the capture of Fe-based fine particles by each fiber
In this work, an existing method of capturing Fe-based fine particles by magnetic fiber is improved, and a weaving method for the fiber filter material is further determined. Different combinations of magnetic fields could form around the magnetic fibers, which change the interaction between orthogonal magnetic fibers when a uniform magnetic field is applied along the X-, Y-, and Z-axes. Therefore, the process of particle capture by the orthogonal magnetic fibers under three configurations was compared using the computational fluid dynamics-discrete phase model (CFD-DPM) and a special user-defined function (UDF) of the magnetic force. The results show that the interaction between orthogonal magnetic fibers could either inhibit or promote the capture of Fe-based fine particles by adjacent magnetic fibers. In industrial production, the magnetic filter material is suitable for the weaving method for the alternate use of magnetic and traditional fibers. When a uniform magnetic field is applied along the X-axis, this weaving method makes the capturing performance of orthogonal magnetic fiber best. Moreover, the magnetic characteristics, flow characteristics, and combination sequence of magnetic fields should be considered. This study provides scientific researchers with new insights for the development of novel high-efficiency fibrous filters to reduce particulate pollutants emissions.
