When the desulfurization wastewater inlet 11 is arranged on a pipeline communicated with the first circulating pump 9, desulfurization wastewater from a desulfurization system enters through the desulfurization wastewater inlet 11 and then is pumped into the first water distribution device 2 through the first circulating pump 9, the desulfurization wastewater is uniformly distributed in the filler evaporation layer 3 and flows downwards into the liquid collection device 4 under the action of gravity, and the liquid collection device 4 mainly has the function of receiving and collecting the desulfurization wastewater falling from the filler evaporation layer 3, so that the desulfurization wastewater is prevented from directly falling into the tower body 1 below the liquid collection device 4 in an uncontrolled manner; and ensures that the flue gas flowing upwards from the lower part of the liquid collecting device 4 can flow into the filler evaporation layer 3 through the liquid collecting device 4, thereby exchanging heat with the desulfurization wastewater.
