摘要/Abstract

摘要： 旋风分离器的运行特性在很大程度上影响流化床锅炉的整体运行效率,其内部的气固两相流呈现复杂的旋涡流动。不同角度的数学模型在展现其运行机理时过于复杂或者片面。对一种筒锥组合、逆流式旋风分离器,进行结构细分,建立其内部参数的机理模型。对于分级分离效率比较了三种切割粒径的计算方法,对于压降进行了结合系统结构的压降细分,并给出不同部分的压降计算模型,传热模型考虑了可燃颗粒的放热过程。借助于仿真,分析了不同输入下模型的输出结果,表明该机理模型能够体现旋风分离器的运行特性,并且模型具备较高的精度。

Abstract: The operating characteristics of the cyclone separator greatly affect the overall operating efficiency of the boiler, the gas-solid two-phase flow in the cyclone separator is complicated by the vortex flow. The mathematical model of different angles has been too complicated or one-sided to show its running mechanism. A mechanism model of the internal parameters of a cone assembly and a counter current cyclone separator has been established. The three cutting diameter calculation methods have been compared for grade separation efficiency. The pressure drop has been combined with the pressure drop of the subdivision of the system structure, and the calculation model for different parts has been presented. The exothermic process of combustible particles has been embodied in the heat transfer model. By means of simulation, the outputs of the model with different inputs have been analyzed, which shows that the model can reflect the operating characteristics of the cyclone separator with higher precision.

Key words: cyclone, cylinder cone assembly, counter current, mechanism model
