In the device, the ammonia in the tail gas is dissolved in soft water to form ammonia-containing soft water, and the other part of the tail gas is discharged to the water ring vacuum pump through the exhaust port 9. When the ammonia content in the soft water reaches a first calibration value, the ammonia-containing soft water in the device is discharged to the washing tank of the belt filter through the drain valve port 10, and the ammonia-containing soft water with an ammonia content of the calibration value is used for the water washing operation of the belt filter to avoid waste caused by direct discharge of ammonia-containing soft water.

[0025] The reciprocating translation mechanism includes a casing 11 which is connected to one side of the steam-water separation tank 1.

[0033] Principle of this embodiment: When spraying soft water, the second motor 18 is started to work, driving the driving gear 19 to rotate. Since the driving gear 19 is engaged with the driven gear 20, the rotating tube 7 is driven to rotate, and the annular spray pipe 8 is driven to rotate, so that the atomization effect of the sprayed soft water is better, thereby improving the contact with the ammonia in the exhaust gas, and dissolving the ammonia in the soft water to form ammonia-containing soft water.
