Cyclone separator is the main equipment for particle removal and screening in thermal power plants, and its internal flow characteristics directly affect the performance of cyclone separator. In order to study the influence of the structural difference of the upper cylindrical section of the cyclone separator on its internal particle motion, the numerical simulation of gas-solid two-phase coupled motion in a linear and a spiral separator was carried out by using computational particle fluid dynamics (CPFD). The results show that the average air velocity of the straight section of the spiral separator is higher than that of the linear separator. At the same time, the outlet speed is large. Within a certain inlet velocity range, the spiral separator is slightly superior in separation effect. The research results provide a theoretical reference for the optimization of later practical engineering technology transformation. |
