Energy consumption and its reduction in the hydrocyclone separation process. III. Effect of the structure of flow field on energy consumption and energy saving principles

The effect of the structure of flow field in the hydrocyclone on energy con sumption was experimentally studied systematically with orthogonal design. The results show that the effect of the inserted central part on energy con sumption is the largest, while that of the underflow pipe is the least. The energy saving performance of the winged core is the best among the inserte d central parts. The time-averaged and fluctuating characteristics of press ure structure in the hydrocyclone with low energy loss were also investigat ed experimentally. Both the time-averaged and fluctuating characteristics o f pressure structure in the hydrocyclone with low energy loss are much diff erent from those in the conventional commercial hydrocyclone. The energy sa ving mechanism was investigated, and the energy saving principles and relev ant measures for hydrocyclones were proposed systematically.
