As shown in FIG. 1, turbulators 200 are provided within the tower cavity 110, the turbulators 200 serving to create a turbulent effect on the flue gas to be treated entering through the air scoop 101.

Turbulence is a state of flow of a fluid. When the flow velocity is small, the fluids flow in layers and are not mixed with each other, and the fluids are called laminar flow or laminar flow; gradually increasing the flow velocity, starting the wave-shaped oscillation of the streamline of the fluid, increasing the frequency and amplitude of the oscillation along with the increase of the flow velocity, and the flow condition is called transition flow; when the flow velocity increases to a great extent, the flow lines are no longer clearly distinguishable and there are many small eddies in the flow field, called turbulence, also called turbulence or turbulent flow.
