摘要：

In order to explore the effect of adsorbent injection in flue with baffles, Fluent software was used for CFD simulation. The k-ε double equation turbulence model, Eulerian-Lagrangian discrete phase model and component equation were selected to explore the particle cross-section coverage, the maximum cross-section concentration, particle residence time, particle mass concentration at flue outlet and pressure drop before and after flue under different arrangements of baffles, which was the evaluation index of the diffusion effect of particles. The results show that when the number of nozzles is 2 or 3, the effect of particle diffusion is the best. When two groups of nozzles are selected, there are no obvious influence on the pressure, velocity, temperature and flow field inside the flue after magnetospheres sorbent injection. At the same time, the high particle coverage can be ensured, which provids a reference for the layout of the magnetospheres sorbent injection device. © 2021, Central South University Press.
