水力旋流器分离性能强化研究

设计了一种在旋流器轴心线位置具有中心固棒的新型水力旋流器,该中心固棒的引入有效地消除了旋流器内的中心空气柱。实验研究了该中心固棒替代空气柱对旋流器性能指标的系统影响。研究结果表明,采用中心固体棒取消旋流器内的空气柱后,旋流器的分离性能得到了有效的强化。与具有空气柱的旋流器相比,不管旋流器锥段结构如何变化(从普通直锥、到抛物线型锥、到双曲线型锥),具有中心固棒的旋流器均具有更高的分离总效率、更高的修正分离总效率、更小的修正分离粒度以及更高的分离精度。随着旋流器锥段内部空间的增大,中心固棒使旋流器分离性能提高的幅度也增大。

Research on Enhancement of Hydrocyclone Separation Performance

A new hydrocyclone was designed with a solid core fixed along the central axis in this study.By introducing the solid core,the air core inside the hydrocyclone could be eliminated effectively.Comprehensive effects of eliminating the air core by the solid core on the hydrocyclone performance indices were experimentally investigated.By eliminating the air core with solid core,the hydrocyclone separation performance was improved effectively.Compared with the hydrocyclones with air core,the hydrocyclones with solid core were all proven to be featured with higher total separation efficiency,larger reduced separation efficiency,smaller corrected cut size and higher separation sharpness,although the hydrocyclone cone shape changed from common type,to parabola type,and to hyperbola type.With increasing the inner space of the hydrocyclone cone,the improvement of separation performance became more remarkable.
