高速逆流分离泵结构设计与流体仿真分析

Structural Design and Fluid Simulation Analysis of High-Speed Countercurrent SeparationPumps

对于植物微量成分的分离与提取,采用的方法多种多样,如传统的水蒸气蒸馏法、煎煮法、回流法等,也有现代使用的超声波辅助法、超临界流体萃取法、微波辅助法等一系列方法。针对传统提取方法的不足之处,设计一种高速逆流分离泵对植物微量成分进行分离与提取,并用流体仿真分析手段对高速逆流分离泵进行流体力学仿真。逆流泵具有体积小、结构紧凑、磨损少、能耗较低等特点,因此植物微量成分可采用多通道逆流泵进行初步的分离与提取。

For the separation and extraction of plant trace components,various methods are used,such as the traditional steam distillation,decoction,reflux method,etc.,but also the modern ultrasonic-assisted method,supercritical fluid extraction,microwave-assisted method and a series of methods.In view of the shortcomings of the traditional extraction methods,a high-speed countercurrent separation pump is designed to separate and extract the trace components of plants,and the high-speed countercurrent separation pump is used for hydrodynamic simulation by means of fluid simulation analysis.The countercurrent pump has the characteristics of small volume,compact structure,less wear and tear,lower energy consumption,etc.Therefore,the plant trace components can be initially separated and extracted by multi-channel countercurrent pump.
