Numerical Simulation and Optimized Design of the Wet Flue Gas Desulphurization Spray Tower
The CFD software Fluent and Gambit had been introduced for the simulation of the flow and temperature fields of the wet desulphurization. The flue gas flow is described using standard k-ε turbulence model and the motion of the liquid droplets is described using the particle path model. The problems of the desulphurization spray tower were found the flue gas stuck tower wall, the distribution of the flow-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 results indicate that the angle of the flue gas entrance was down to 15°, the turbulence in right side of the tower was intensify, and the flue gas stuck tower wall had an improvement in left side of the tower. The desulfurization spray tower was installed the flue gas distributor in area of atomization down spray layers, the flue gas was made circumfluence follow the flue gas distributor and flowed in Dense-Phase Zone of spray. At the same time the gas temperature of the export was lower than before the reformation. The study results supplied the basis of optimization of the structure to desulphurization spray tower.
