轴流式旋流分离器的设计及试验装置改造 摘 要 水力旋流器是一种结构紧凑，分离效率高的分离设备，广泛应用于冶金，石化， 环保等行业中。本文根据国外已有资料数据，完成一台轴流式旋流分离器的设计；并 应用 FLUENT 软件对设计出的分离器进行模拟研究，根据流体在旋流器内强旋流的特 点，采用了各项异性的雷诺应力模型（RSM ，Reynolds Stress Model ）。首先模拟了旋 流器内单相流体的流动情况，研究其速度及压力分布。在此基础上应用 MIXTURE 模 型对油水混合物进行了分离模拟，分别考察了进出口质量流量。并根据文中设计的轴 流式旋流分离器完成对试验用分离器的设备改造。 关键词：轴流式，旋流器，设计，改造，数值模拟 III 轴流式旋流分离器的设计及试验装置改造 Abstract The hydrocyclone is a kind of separator with a compact structure and high separating efficiency. It is applied extensively to industrial fields such as metallurgy, petro-chemistry, and environment protection. In this paper, a design of axial-hydrocyclone is related 。And the flow field of Axial-cyclone is simulated by the FLUENT software package. Considering the strongly swirling turbulent flow in hydrocyclone, numerical calculation is based on the anisotropic Reynolds Stress Model(RSM). At first the single-phase fluid flow was calculated and the velocity and the pressure was analyzed. On the basis of single-phase, two phases of water/oil were simulated by the MIXTURE model, and analysis of mass flow rate of the inlet and the two outlets(outlet-oil and outlet-water) was fixed. Finally, due to the design of axial-hydrocyclone, finish the optimization of experiment equipments.
