Entrance Angle

Calculation fluid dynamics software Fluent was used to conduct three-dimensional numerical simulation on gas-liquid two-phase flow field in a wet flue gas desulfurization scrubber. The k-ε model and SIMPLE computing were adopted in the analysis. The numerical simulation results show that the different gas entrance angles lead to internal changes of gas-liquid two-phase flow field, which provides references for reasonable parameter design of entrance angle in the scrubber.

Design And Application

The wet flue gas desulfurization is the main technology used today in China. Aimed the sintering gas desulfurization tower, Fluent software is used here to simulate the flow in the tower with different gas entrance angle and velocity, and we have got the effect of sintering gas entrance angle and velocity on the flow in the tower. The result shows: an appropriate increase of the gas entrance velocity and a downward inclined angle will be helpful for extending the residence time in the tower of the sintering gas and it will also improve the flow in the tower. This research could provide reference for the design and application of new wet flue sintering gas desulfurization tower later.
