Study on the effect of the aspect ratio of rectangular inlet nozzle on the performance of gas-liquid cylindrical cyclone separator
The advantages and application scope of gas-liquid cylindrical cyclone separator is introduced.Under the condition of maintaining the area of the rectangular nozzle at the inlet unchanged,the aspect ratio of the rectangular inlet nozzle with the best separation performance of the separator is determined by numerical simulation,which provides some guidance for the design and optimization of tubular gas-liquid separator.The results show that when the tapered area is constant and the rectangular aspect ratio is 2.5,the tangential velocity at inlet is the largest,the liquid volume fraction on the section of the inlet cylinder is the largest,and the separation efficiency of the separator is the highest.At higher viscosity,the effect of gas-liquid cylindrical cyclone separator is the best when the aspect ratio of rectangular inlet nozzle is 2.5.However,the pressure drop is the smallest when the aspect ratio of rectangular inlet nozzle is 3.5.Therefore,considering the influence of separation efficiency and pressure drop of the separator,it is determined that the optimal aspect ratio of rectangular inlet nozzle of the gas-liquid cylindrical cyclone separator is 2.5.
