摘要

To optimize the two-phase flow characteristics of flue gas and slurry droplets in spray drying tower

an equalizing plate was installed inside the tower.The Fluent software package

turbulence model and the stochastic model of droplet track were adopted in numerical simulation.Results showed that

the average speed of flue gas along the tower axis was the greatest;the temperature variation in the vicinity of spray nozzle was the largest;when the inlet flue gas speed v was 4 m / s

the temperature gradient variation inside the tower was the maximum

and the slurry droplets full filled the tower;with an increase in the diameter of hole area on equalizing plate

the resistance in tower was gradually decreased

and the viscosity to the wall of slurry droplets first increased and then reduced.
