立体旋流筛板气相流场结构优化

立体旋流筛板是一种具有良好发展前景的新型塔板元件，为了进一步扩展立体旋流筛板的设计空间以及应用范围，对其进行结构上的优化，去除塔板叶片上的筛孔，使其制作工艺简单，造价低廉，之后应用FLUENT计算流体力学软件对优化后的立体旋流筛板内的气体单相流场进行模拟计算，通过与实验结果进行对比，吻合较好，证明了模拟结果的准确性，之后与立体旋流筛板模拟结果进行对比分析。结果表明：优化后的立体旋流筛板的能量损失较小，速度幅值较大，速度分布梯度更加明显，气体湍动更加剧烈，并且压降相对更小，适合高湍动低压降的工况，达到了结构优化的目的，同时对于今后立体旋流筛板的结构优化以及工业应用具有指导意义。

Optimization Structure of Gas Phase Flow Field of Tridimensional Rotating Sieve Tray

Tridimensional rotating sieve tray is a have good prospects for development of new type of plate elements, in order to further expand the design space and application range of tridimensional rotating sieve tray, and structural optimization of it, to remove the mesh on the plate blade, make its production process is simple, low cost, after FLUENT computational fluid dynamics software was applied to optimize the tridimensional rotating sieve tray after simulated calculation of single phase flow of gas, through compared with the experimental results and are in good agreement, and proves that the accuracy of the simulation results, and tridimensional rotating sieve tray after the simulation results were analyzed.Results show that the optimized tridimensional rotating sieve tray energy loss is small, velocity amplitude is larger, more apparent velocity distribution gradient, gas of more intense turbulent motion and pressure drop are relatively small, suitable for high turbulent condition of low pressure drop, achieved the purpose of structural optimization, at the same time for future tridimensional rotating sieve tray structure optimization, and has guiding significance for industrial application.
