Flow Structure of New Quick-Contact Cyclone Reactor

Abstract:

The gas flow structure of new quick-contact cyclone reactor was simulated by using Reynolds stress model of Computational Fluid Dynamics method. In preliminary work, it had been proved that the simulated results agreed well with the experimental results. The results show that: ⑴ in mixer region, the three-dimensional velocities of gas flow are very small and the vertical vortexes cover the most part of the mixer which could contribute to gas-solid mixing effect; ⑵ in separator region, the rotation intensity of gas flow is very strong through accelerating action of guided vanes. However, some vortexes exist near the entrance of exhaust pipe and dust hopper which is not conductive to separation efficiency. The results could play a directive role in mass and heat transfer process and catalytic cracking reaction in cyclone reactor.
