Separation Law of High Gas Content Spiral Cylindrical Gas-liquid Separator
At present,the research on spiral gas-liquid separator mostly focuses on the separation perform-ance under low gas volume fraction conditions,and there is relatively little research on that under high gas volume fraction conditions.To solve this problem,the concentration field changes of the spiral gas-liquid separator under low and high gas content conditions were compared,and the gas volume fraction at apex,liquid removal efficien-cy,degassing efficiency and tangential velocity field of the spiral gas-liquid separator under low and high gas con-tent conditions were analyzed.The research results show that during the continuous increase of the gas volume frac-tion at inlet,when it reaches 50%,the gas phase is almost uniformly distributed throughout the gas-liquid separa-tor,and there is no obvious liquid phase concentration area in the gas-liquid separator.When the gas volume frac-tion at inlet reaches 70%,the maximum gas volume fraction in the bottom flow reaches 49.5%,and the apex car-ries gas severely;meanwhile,the liquid removal efficiency decreases from the initial 96.9%to 55.4%,and the degassing efficiency increases from 43.9%to 80.8%.The research results provide theoretical basis for the model structure optimization design of spiral gas-liquid separators under high gas content conditions.
