Abstract
Description
Technical Field
[0001] This utility model relates to the field of ammonia absorption technology, specifically to a distributed ammonia absorption device for pig farms. Background Technology
[0002] In hot and humid environments, the decomposition of pig manure and urine in pig farms produces a large amount of ammonia. Excessive ammonia concentration can harm the health of pigs, increase the risk of respiratory diseases, and also pollute the surrounding environment.
[0003] To reduce the harm caused by ammonia, ammonia absorption devices are installed in pig farms. Pig farms typically have multiple compartments, each producing varying amounts of ammonia. Conventional ammonia absorption devices struggle to effectively absorb ammonia in a timely manner, leading to the accumulation of ammonia in some compartments, severely harming the health of the pigs. Furthermore, conventional ammonia absorption devices often fail to completely absorb ammonia, resulting in purified air containing significant amounts of ammonia. Direct release of this ammonia into the environment causes severe pollution and damages the surrounding ecosystem. To address these issues, a distributed ammonia absorption device for pig farms is proposed. Utility Model Content

This solution overcomes the limitations of current methods that rely on ammonia absorption devices installed in pig farms to reduce the harm caused by ammonia. Pig farms typically have multiple compartments with varying amounts of ammonia produced in each compartment. Conventional ammonia absorption devices struggle to effectively absorb ammonia in a timely manner, leading to the accumulation of excessive ammonia in some compartments, which seriously harms the health of pigs. Furthermore, conventional ammonia absorption devices often fail to completely absorb ammonia, resulting in a high ammonia content in the purified air.

[0019] Reference Figure 1-3 As shown, a distributed ammonia absorption device for pig farms includes an absorption cylinder 1, a drain pipe 2 fixedly connected to the lower front end of the absorption cylinder 1, a first solenoid valve 3 fixedly installed on the drain pipe 2, and an inlet pipe 4 fixedly connected to the upper front end of the absorption cylinder 1, a second solenoid valve 5 fixedly installed on the inlet pipe 4, effectively managing the input and discharge of the absorption liquid.
[0020] Specifically, a first ammonia sensor 6 is fixedly installed at the center of the upper side inside the absorption cylinder 1 to monitor the ammonia concentration at the upper end of the absorption cylinder 1 in real time, facilitating timely replacement of the absorbent liquid by staff. A connecting pipe 7 is fixedly connected to the upper left end of the absorption cylinder 1. The lower end of the connecting pipe 7 passes through the top plate of the absorption cylinder 1 and connects to the lower end of the absorption cylinder 1, ensuring full contact between the ammonia and the absorbent liquid. A fan pipe 8 is fixedly connected to the left side of the connecting pipe 7. An axial flow fan is installed inside the fan pipe 8. An air inlet pipe 9 is fixedly connected at the center of the left side of the fan pipe 8. A collection pipe 10 is fixedly connected to the lower end of the air inlet pipe 9. Several air inlet hoppers 11 are fixedly connected to the lower side of the collection pipe 10 to effectively absorb ammonia from various parts of the pig farm. A second ammonia sensor 12 is fixedly installed on the right side of the air inlet hopper 11 to monitor the ammonia concentration at various parts of the pig farm in real time. An exhaust pipe 13 is fixedly connected to the upper right end of the absorption cylinder 1. The lower end of the exhaust pipe 13 passes through the top plate of the absorption cylinder 1 and connects to the upper end of the absorption cylinder 1.
[0021] Specifically, a filter box 14 is fixedly connected to the right side of the exhaust pipe 13. Several mounting slots 15 are opened through the upper side of the filter box 14. Mounting frames 16 are slidably connected inside the mounting slots 15. The front and rear sides of the mounting frames 16 are slidably connected to the inner wall of the filter box 14. Filter plates 17 are snapped into the inside of the mounting frames 16, and ammonia is effectively adsorbed by activated carbon. A handle 18 is fixedly connected to the center of the upper side of the mounting frames 16, making it convenient for staff to pull out the mounting frames 16 to replace the filter plates 17. A fixing frame 19 is rotatably connected to the upper left side of the filter box 14 via a hinge. A fixing bolt 20 is threadedly connected to the upper right side of the fixing frame 19. The end of the fixing bolt 20 passes through the upper side of the fixing frame 19 and is threadedly connected to the upper side of the filter box 14, effectively fixing each mounting frame 16.
[0022] Working principle: Several air intake hoppers 11 are installed in various compartments inside the pig farm. Absorbent liquid is injected into the absorption cylinder 1 through the liquid inlet pipe 4 and flows down to the bottom of the exhaust pipe 13. When the second ammonia sensor 12 detects that the ammonia exceeds the set standard, the axial flow fan inside the fan pipe 8 rotates. The ammonia gas enters the collection pipe 10 through the air intake hopper 11 with the air, and enters the lower part of the absorption cylinder 1 along the air inlet pipe 9 and the connecting pipe 7. After contacting the absorbent liquid, it is absorbed by the absorbent liquid. When the absorbent liquid reaches saturation, the first ammonia sensor 6 will detect a significant increase in ammonia concentration. At this time, the first solenoid valve 3 is opened, and the saturated absorbent liquid is discharged through the drain pipe 2. The second solenoid valve 5 is opened to input new absorbent liquid. A small amount of ammonia gas will enter the exhaust pipe 13 with the air and enter the filter box 14. The ammonia gas is adsorbed by the filter plate 17, and the air is purified for a second time to prevent ammonia gas from being discharged into the external environment.
