摘要:
为了进一步提高小型水力旋流器分离细微颗粒的能力，提出一种新型抛物面壁水力旋流器。应用计算流体力学软件Fluent分析比较了抛物面壁和圆锥面壁在不同条件下的分离特性、内部流场及颗粒物轨迹规律。在综合考虑分离效率以及体积大小的基础上，对抛物面壁进行选型优化。结果表明，抛物面壁旋流器各项分离性能的指标均更佳，压力梯度与速度梯度优势更明显，整体分离效率更高。得到最佳结构参数为，底流口直径8 mm、锥体高度175.54 mm，抛物线方程为y=-0.391 64x2+19.716 6x-318.14。
Abstract:
In order to enhance the efficacy of small hydrocyclones in the separation of fine particles, a new type of parabolic wall hydrocyclone was proposed. Computational fluid dynamics software Fluent was employed to analyse and compare the separation characteristics, internal flow field and particle trajectory law of parabolic and conical walls under different conditions. In light of the aforementioned criteria, the parabolic wall was selected and optimised. The results demonstrate that the new parabolic wall cyclone exhibits superior separation performance indicators, a more pronounced pressure and velocity gradient, and enhanced overall separation efficiency. The optimal parameters are as follows: the diameter of the bottom flow opening is 8 mm, the height of the cone is 175.54 mm, and the parabolic equation is y=-0.391 64 x2+19.716 6x-318.14.
