As shown in fig. 1, the desulfurization wastewater concentration system for preventing a sprayer from being blocked provided by the embodiment of the utility model comprises a concentration tower 1, a first thick slurry circulating pump 5 and a first solid-liquid separator 6; the inlet of the concentration tower 1 is used for being connected with a wastewater source 7, the outlet of the concentration tower 1 is used for being connected with a thick stock box 2, and a spraying layer 8 is arranged in the concentration tower 1; the first thick slurry circulating pump 5 is connected to the lower part of the concentration tower 1; the input port of the first solid-liquid separator 6 is connected with the first thick slurry circulating pump 5, the liquid output port of the first solid-liquid separator 6 is connected to the position on the concentration tower 1 corresponding to the spraying layer 8, and the solid outlet of the first solid-liquid separator 6 is used for connecting the thick slurry tank 2.
In the embodiment of the present utility model, the entire shape of the concentration column 1 is substantially cylindrical, and the interior thereof is hollow. The input port of the first thick liquid circulating pump 5 is connected to the lower position of the side surface of the concentration tower 1, the output port of the first thick liquid circulating pump 5 is connected with the first solid-liquid separator 6 to input the solid-liquid mixture from the concentration tower 1 into the first solid-liquid separator 6, and under the action of the first solid-liquid separator 6, the solid and the liquid in the solid-liquid mixture are separated from each other, wherein the solid outlet of the first solid-liquid separator 6 is fixedly discharged into the thick liquid box 2, and the liquid is discharged from the liquid outlet of the first solid-liquid separator 6 and reenters the concentration tower 1. Under the action of the first solid-liquid separator 6, the liquid re-entering the concentration tower 1 has small solid content and basically smaller diameter, the spray layer 8 (i.e. sprayer) is not easy to be blocked, and the device in the spray layer 8 is not easy to be worn, so that the long-time stable operation of the concentration system can be ensured.
In the embodiment of the utility model, the number of the spraying layers 8 in the concentration tower 1 can be multiple layers. Specifically, taking the whole shape of the concentration tower 1 as a cylindrical shape as an example, the spraying layers 8 in the concentration tower 1 are arranged in multiple layers and equidistantly along the axial direction of the concentration tower 1, and a plurality of spraying devices 9 can be arranged in each spraying layer 8, so that liquid can be more uniformly dispersed in the concentration tower 1, and the treatment is more thorough. When the number of the spray layers 8 is multiple, the liquid outlet of the first solid-liquid separator 6 may be connected to the concentration tower 1 at a position corresponding to the uppermost spray layer 8, so that the liquid subjected to solid-liquid separation may be dispersed more uniformly after re-entering the concentration tower 1.

The gas entering from the inlet flue 10 passes through the spraying layer 8 and is discharged from the main flue 12, so that the supply of the gas in the concentration tower 1 is completed.
In some embodiments, the inlet stack 10 is configured with a booster fan 11. Through the arrangement of the booster fan 11, the efficiency of gas entering the concentration tower 1 can be increased, and the pressure of gas entering the concentration tower 1 can be realized through adjusting the power of the booster fan 11, so that the device is suitable for various working conditions in the concentration tower 1.
