针对固 液分离水力旋流器 ,研究了结构参数及操作参数对压力特性的影响 ,得到了含气条件下水力旋流器的压力特性研究结果 ,并进行了能耗分析。实验结果表明 ,在含气条件下水力旋流器的溢流和底流压差都显著增加 ;在不含气条件下压降比随着流量的增加而降低 ,但在含气时则基本保持不变 ;随着旋数的增加 ,压差增大 ,而压降比减小 ;随着气 液比的加大 ,压差基本呈增加趋势 ,而压降比则无明显变化。最后指出 ,减少水力旋流器能量消耗的方法主要有降低流量、旋数或气 液比 ,其中最可行的方法是降低水力旋流器入口处的气 液比 ,即提高游离水脱除器等前端处理设备的除气效率 ,尽可能降低混合介质中气体的含量
For the hydrocyclone with solid-liquid separation, the influence of structural parameters and operating parameters on the pressure characteristics was studied. The pressure characteristics of hydrocyclones under gas-containing conditions were studied and the energy consumption analysis was carried out. The experimental results show that the hydrocyclone overflow pressure and underflow pressure increase significantly under the condition of gas, while the pressure drop ratio decreases with the increase of flow rate in the absence of gas, but remains basically unchanged The pressure drop increases with the increase of spin number, while the pressure drop decreases. With the increase of gas-liquid ratio, the pressure drop basically increases while the pressure drop ratio does not change significantly. Finally, it is pointed out that the methods of reducing the energy consumption of the hydrocyclone mainly include reducing the flow rate, the number of revolutions or the gas-liquid ratio. The most feasible method is to reduce the gas-liquid ratio at the inlet of the hydrocyclone, that is, to increase the free water remover Outgassing efficiency of the front-end processing equipment minimizes the amount of gas in the mixing medium
