Analysis of Flow Field of Built-in Vane of Cyclone Separator
The cyclone separator is the core equipment for sand removal in the field of oil and gas extraction.In order to study the impact of structure on separation efficiency,a new built-in guide vane was designed.Based on CFD,fluent software was used to analyze the flow field of the new cyclone separator.The results show that the maximum tangential velocity of the cyclone separator with built-in guide vanes is significantly improved com-pared to the traditional Stairmand separator,with a small decrease in radial velocity,a decrease in axial velocity,and an extension of particle stagnation time.When the inlet wind speed is 15m/s,the pressure drop increases by 15%.As the inlet wind speed increases,the amplitude of the pressure drop increase decreases.At 25m/s,the pressure drop increases by 11%.For particle size 2.5 μThe separation efficiency of particles below m has in-creased by an average of 11%to 19%,providing guidance for the subsequent design of cyclone separators.
