[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0023] A tail gas recovery device for ammonia water production, including a recovery box body 1. In the middle of the upper end of the recovery box body 1, a fan 5 is inserted and connected. In the upper part, middle part, and right part of the left end of the recovery box body 1, a feed pipe 6, a collection pipe 9, and a drain pipe 10 are respectively inserted and connected. Slide grooves 8 are opened between the upper parts of the left and right box walls of the recovery box body 1. A purification device 7 is slidably connected to the upper part of the inner box wall of the recovery box body 1. A spraying device 4 is fixedly connected to the right end of the recovery box body 1. A number of packing balls 3 are filled in the lower part of the inner box wall of the recovery box body 1. The front end of the recovery box body 1 is movably installed with a transparent cover door 2 through a hinge;

[0024] The spraying device 4 includes a water storage tank 43. In the middle of the upper end of the water storage tank 43, a connecting pipe 45 is fixedly connected. A switch control valve 44 is arranged on the outer surface of the connecting pipe 45. The other end of the connecting pipe 45 is fixedly connected to a water box 42. A number of spray heads 41 are fixedly connected to the lower end of the water box 42. The water storage tank 43 is fixedly connected to the right end of the recovery box body 1. The water box 42 is internally communicated with the water storage tank 43 through the connecting pipe 45. Since the water box 42 is internally communicated with the water storage tank 43 through the connecting pipe 45, when the switch control valve 44 is opened, water is pumped from the water storage tank 43 to the water box 42 through the connecting pipe 45 and sprayed by a number of spray heads 41, so that ammonia gas and pure water are fully contacted, and ammonia gas is fully absorbed, and the recovery is completely reliable.

[0025] In this embodiment, the purification device 7 includes a sliding plate 71. An activated carbon cotton layer 72 is fixedly connected to the upper end of the sliding plate 71. The sliding plate 71 is slidably connected within the recovery box body 1. The left and right sides of the sliding plate 71 are respectively slidably connected within the sliding grooves 8. By respectively slidably connecting the left and right sides of the sliding plate 71 within the sliding grooves 8, the sliding plate 71 is slidably installed within the recovery box body 1. The sliding installation method is convenient for disassembly and use.

[0026] In this embodiment, several packing balls 3 are all located directly below the activated carbon cotton layer 72.

[0027] It should be noted that the present utility model is a tail gas recovery device for ammonia water production. During use, ammonia water enters the recovery box body 1 from the feed pipe 6. The ammonia gas generated by turning on the blower 5 is effectively filtered through the activated carbon cotton layer 72 and then enters the surface of the packing balls 3. By arranging several packing balls 3 at the lower part of the inner box wall of the recovery box body 1, and arranging the several packing balls 3 from top to bottom and from small to large, the entering ammonia gas slowly rises. Then, in cooperation with the spraying device 4, the switch control valve 44 is turned on, water is pumped from the water storage tank 43 to the water box 42 through the connecting pipe 45 and is sprayed by several spray heads 41, so that the ammonia gas fully contacts with pure water, and the ammonia gas is fully absorbed. The recovery is completely reliable. After the ammonia gas dissolves in water, it sinks. Under the lower packing balls 3, there is less obstruction, so that the ammonia gas quickly descends and is discharged from the collection pipe 9, achieving a good purification effect and a good recovery and utilization effect.

[0028] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
