摘要
水力旋流器利用颗粒-颗粒或颗粒-流体在旋流流场中运动行为差异实现分级分离过程,被广泛地应用于化工、冶金、矿物加工和环保等行业。在实际运行中,由于操作条件不合理或设备结构条件限制,使颗粒分级或固液分离性能无法满足应用需求,本文分析了水力旋流器的流场特征,并总结了影响旋流器分离性能的关键因素。水力旋流器内部呈现复杂的多相流场,颗粒性质、料液性质、进料条件等操作参数和旋流器的几何结构会影响水力旋流器的分离性能,实际应用中可以通过优化运行条件和旋流器的几何结构,提高旋流器的分级分离性能。
The primary separation principle of hydrocyclones is the dynamic behavior difference between particle-particle or particle-fluid.Hydrocyclones are widely applied in the fields of chemical engineering,metallurgy,mineral engineering,and environmental protection.In industrial runs,the unreasonable operating conditions or the limit of the geometric structure prevent the devices from achieving a satisfying classification or separation performance.This review summarizes the flow field characteristics and the key factors affecting the separation performance of the hydrocyclone.The complex multiphase flow field is presented inside the hydrocyclone,and the operating parameters such as particle properties,feed liquid properties,feed conditions,and geometric structures will affect the separation performance of the hydrocyclone.In practical applications,the classification and separation performance can be enhanced through the optimization of the operating conditions and geometric structures.
