Numerical Simulation Study of Wet Desulfurization in Demister in San-He Power Plant

Abstract:

In order to use the demister more scientifically and rationally, the numerical simulation of gas-liquid two-phase flow was implemented in two dimensional demister blades by different combinations of parameters using FLUENT software. The relationship between either the pressure drop or demisting efficiency and these factors of droplet diameter, gas velocity and plate spacing in san-he power plant was obtained respectively. The simulation shows that: With the change of the droplets diameters and blades spacing, the import and export pressure drop almost have no change. But it will increase with the increasing of gas velocities; With the increasing of droplets diameters, the demisting efficiency is increasing rapidly; The demisting efficiency increases with the increasing of gas velocities and decreases with the increasing of blades spacing.Keywords: Numerical Simulation, droplet diameter, gas velocity, plate spacing.
