内部温度会根据旋风除尘器的运行条件和材料的不同而变化。对除尘器壁面不同热流密度下的除尘效率和温度分布进行了比较。利用前人的实验结果验证了CFD(计算流体动力学)模型的可靠性。基于此验证的CFD模型，对旋风除尘器进行了扩展分析。在CFD研究中，采用RNG k-epsilon模型对湍流流动进行分析，流体为空气，入口速度为10m/S，空气温度为。由于外涡和内涡温度的差异，集热效率会随着热流密度的增加而降低，表现为绝热时集热效率最高。
The internal temperature will change depending on operation conditions and material of cyclone dust collector. This study compares the results of collection efficiency and temperature distribution on the different heat flux at wall of dust collector. The previous researcher's experiment results were used to confirm the reliability of CFD (Computational Fluid Dynamics) model. Based on this verified CFD model, we extended the analysis on the cyclone dust collectors. In CFD study, we used RNG k-epsilon model for analysis of turbulence flow, fluid is air, the velocity at inlet is 10 m/s, the temperature of air is. Because of the difference of outer vortex and inner vortex temperature, the collection efficiency will reduce with the increase of heat flux, showed the highest collection efficiency at heat insulation.
