Abstract:

Abstract:The absorption tower design is key technology for realization of localization and independence of the wet FGD technology. Using software Pro/Engineering, the empty tower model of absorption tower was established. Using the computational fluid dynamics software Ansys CFX, the gaseous phase dynamic flow field in absorption tower was simulated. The influence of different outlet forms of absorption tower on its performance was discussed and compared, and the distribution of the pressure and the vector velocity in tower were compared, which provide some guidance for subsequent simulation and optimization of flow field in absorption tower.
