The internal flow field of a desulfurization spray tower was numerically simulated by Fluent software.Three factors affecting the flow field was investigated
such as the slurry spraying
adding a baffle at the flue gas entrance and waste heat utilization.The results show that
spraying the slurry improved the uniformity of gas flow field
eased the effect of reflux and increased the outlet gas velocity by about 10%.Installation of a baffle can help the gas flow overcome the phenomenon of sticking wall and make the gas flow more uniform.Low temperature waste heat utilization decreased the mass flux of the gas and increased the density of gas in the tower
which made the flow field distribution of gas in the tower more uniform
