Inner channels are installed in the separator to reduce re-entrainment of particles and improve separation efficiency.The comprehensive performance of the separators with or without inner channels is analyzed by experiments.The fluid flow field is analyzed by the Reynolds stress model and particle trajectory is predicted with the discrete phase model.The results show that the maximum separation efficiency of the separator with inner channels is 96.15％,and the pressure drop is 1 765 Pa,which can inhibit the re-entrainment of particles and improve the separation efficiency.Simultaneously,the inner channels increase the airflow resistance along the path and local resistance,making the pressure drop higher than the conventional separator and enhancing the inertia of particles in the airflow,which leads to more chaotic particle movement.
