Numerical study on the optimization of flow and temputre field in the desulphurization spray tower
The CFD software Fluent and Gambit had been introduced for the simulation of the owand temperature fields of the wet ue gas desulphurization. Standard k- turbulence model and theparticle path model described the motion of the ue gas and the liquid droplets. The problems of thedesulphurization spray tower were found the ue gas stuck tower wall, the distribution of the ow-fields was not an ideal state and the temperature of the export was higher by numerical simulation.Aiming at these problems it was optimized design by numerical simulation. The simulation resultsindicate that the angle of the ue gas entrance was down to 15_and installed the ue gas distributorin area of atomization down the spray layers, the ue gas following along the tower wall was overcome.At the same time the gas temperature of the export was lower than before the modification. Thestudy results supplied the basis of the optimization of the structure of desulphurization spray tower.
