[0027] A flue gas inlet 11 is provided at the bottom of one side of the cooling tower 12, and a flue gas exhaust pipe 13 is provided at the top of the other side of the cooling tower 12. The flue gas exhaust pipe 13 extends vertically downward and the bottom end is connected to the absorption tower 14. The flue gas inlet 11 enters the cooling tower 12 from the bottom, is cooled with the multi-layer spray gun structure, and then enters the absorption tower 14 for secondary impurity removal.

[0028] A flue gas exhaust port 15 is provided on the outer top of the absorption tower 14 , and the purified gas is discharged through the flue gas exhaust port 15 .

[0029] A water receiving pipe 16 is connected to the bottom center of the booster water storage tank 6, and a pressure display 17 is arranged on the water receiving pipe 16. A spare valve 18 is also arranged on the water receiving pipe 16. By using the water receiving pipe 16, the pressure display device 17 and the spare valve 18, the expansion needs of the equipment can be guaranteed.

[0030] The spray gun structure 9 includes a main through pipe 19, and a plurality of branch pipes 20 are equidistantly connected to the inner side of the main through pipe 19. The plurality of branch pipes 20 extend to the interior of the cooling tower 12. The multi-layered branch pipes 20 are used for cooling and spraying water to improve the cooling effect.

[0031] The inside of the flow diversion pipe 20 is connected to an annular flow guide pipe 21, and a plurality of nozzles 22 are evenly arranged on the inner wall of the flow guide pipe 21. By using the flow guide pipe 21 and the nozzles 22 to perform uniform multi-area spraying, a good cooling effect is achieved.

[0032] Several ball rings are arranged inside the absorption tower 14, and the ball ring packing layer height is between 500-1000mm. Such a design can promote full contact between flue gas and circulating water, so that boron oxides, nitrogen oxides, etc. in the flue gas can be fully absorbed.

[0033] Working principle: the booster water pump and the inlet and outlet valves, pressure gauges, etc. are all used in one and standby mode to ensure timely switching in case of failure. The lower part of the booster water storage tank is connected to the cooling tower and the absorption tower using water pipes, a three-way structure, leaving a subsequent water pipe 16, a pressure display device 17, and a spare valve 18 to ensure the needs of equipment expansion. The high-temperature flue gas of the glass pool furnace passes through the flue gas inlet 11, the cooling tower 12, and the flue gas exhaust pipe 13, and then enters the absorption tower 14. After passing through the cooling tower and the absorption tower, the flue gas is dusted and cooled, and then discharged into the wet electrostatic precipitator through the fan. Finally, after the electrostatic precipitator, the flue gas is finally treated and discharged into the chimney.

After spraying, it exits the cooling tower from the high side, enters the absorption tower through the low part, and after being sprayed by the high-altitude spray gun, the absorption tower is equipped with fillers (ball rings, stacking height 500mm-1000mm), which can promote the full contact between the flue gas and the circulating water, so that the boron oxides, nitrogen oxides, etc. in the flue gas can be fully absorbed, so that the flue gas can meet the emission standards after purification. The high-temperature dirty flue gas flows through the two towers, and the efficient spraying of the mist nozzle gun installed inside and the absorption of the thick layer of ball rings can efficiently deal with the dust in the pool furnace flue gas. The cooling water used is circulated and pressurized to ensure that the water used in the cooling tower and the absorption tower has a high water pressure and sufficient water volume, so as to maintain a good treatment effect on the dust in the flue gas.
