Spray Drying Absorber (SDA) has been widely used for large-scale desulfurization. However, it also has some
limitations. For example, the liquid absorbent easily causes scaling, which impedes the contact between the serous
fluid and the flue gas and reduces the chemical reaction rate and desulfurization efficiency. This paper establishes
the mathematical and physical model of gas and liquid two-phase flow and droplet evaporation and heat transfer
in rotary spray desulfurization tower. To study the accumulation and distribution of chemical reaction precipitates
in the desulfurization tower and analyze the removal efficiency of sulfur dioxide (SO2) in different atomization diameters, this paper establishes a simulation model concerning the coupling of desulfurization reaction and flow field
calculation based on the absorption and reaction mechanism of SO2. Baffle in different widths are set to optimize
the internal floweld and balance the distribution of flue gas. By setting baffles of different widths to optimize the
flow feld in the tower and changing the distribution of flue gas, this model reduces the scaling while ensuring the
desulfurization efficiency. The results of the simulation experiment have verified that the droplet with a diameter
of 50 μm is the optimal option, which can effectively remove the scaling and ensure that the desulfurizing tower
runs in high efficiency and stability. When the width of baffes is 2250 mm, the efficiency of desulfurization exceeds
95%, and the amount of scaling on the desulfurization tower main wall is controlled at the minimum level, which
is the optimal option for production.
