[0002] With the rapid development of my country's animal husbandry, the scale, intensification, and mechanization of livestock farms have gradually increased. Air pollution in livestock and poultry farms mainly comes from odorous gases emitted within the farms. Fermentation of livestock and poultry manure and wastewater produces large amounts of harmful gases such as ammonia, leading to increased ammonia emissions per unit area of the farm sheds. Ammonia not only easily causes stress in animals, significantly affecting their growth rate and feed conversion ratio, but also seriously pollutes the environment, becoming a breeding ground for mosquitoes, flies, and bacteria, and a source of disease transmission, harming livestock and poultry health and affecting normal human life. Therefore, exhaust gas purification and treatment devices are used at the end of chicken houses.
[0003] Currently, exhaust gas purification devices at the tail end of chicken houses generally involve setting up gas collection hoods at the tail end or key areas of the chicken house, using a negative pressure suction system to collect the exhaust gas, and then guiding the exhaust gas into a purification device equipped with an activated carbon filter for purification. However, the purification effect of activated carbon filters alone is not good enough. Therefore, it is necessary to propose an exhaust gas purification device at the tail end of chicken houses to solve the above problems. Utility Model Content

[0008] In order to facilitate full contact between the exhaust gas and the purification liquid, the second drainage chamber and the first drainage chamber are preferably distributed vertically and horizontally in the exhaust gas purification treatment device at the tail end of the chicken house according to the present invention.
[0009] To facilitate the detection of the liquid level inside the collection box, as a preferred embodiment of the chicken coop exhaust gas purification and treatment device of this utility model, the collection box is equipped with a liquid level gauge inside and a drain pipe is connected to the outer wall, and a shut-off valve is installed on the outer wall of the drain pipe.

The lower end of the vertical pipe 11 is connected to a collection box 7. A storage box 6 is installed at the left end of the collection box 7. The outer walls of the storage box 6 and the collection box 7 are respectively connected to a first drainage pipe 8 and a second drainage pipe 9. The other ends of the first drainage pipe 8 and the second drainage pipe 9 pass through the box 4 and are respectively fixedly connected to a first drainage cavity 14 and a second drainage cavity 13. A liquid pump is installed on the outer wall of the first drainage pipe 8 and the second drainage pipe 9.

[0020] A ventilation device is installed between the canopy 1 and the box 4.
[0021] In this embodiment: During use, the purified liquid is stored inside the storage tank 6. By activating the pump of the first drainage pipe 8, the purified liquid inside the storage tank 6 is transported through the first drainage pipe 8 to the first drainage chamber 14 connected thereto, and sprayed out through the nozzle at the lower end of the first drainage chamber 14. At this time, the exhaust gas inside the shed 1 is introduced into the box 4 through the ventilation device. The purified liquid sprayed through the first drainage chamber 14 and the nozzle can easily perform primary purification of the exhaust gas. After passing through the box 4, the liquid flows into the collection tank 7 through the vertical pipe 11. Activating the pump on the outer wall of the second drainage pipe 9 can easily guide the liquid inside the collection tank 7 to the second drainage chamber 13 through the second drainage pipe 9, and spray it out through the nozzle to perform secondary purification of the exhaust gas. Finally, the exhaust gas undergoes tertiary purification through the activated carbon filter 21 inside the exhaust pipe 5, improving the overall purification effect.
[0022] As a technical optimization of this utility model, the air extraction device includes a horizontal pipe 12 connected to the box body 4. The other end of the horizontal pipe 12 is connected to a cavity 3. A suction fan 16 and a filter screen 17 are installed in the cavity 3 from left to right. The right end of the cavity 3 is connected to a conveying pipe 2. The right end of the conveying pipe 2 passes through the canopy 1 and is connected to two U-shaped pipes 18. Multiple evenly distributed exhaust pipes 19 are installed on the outer wall of the U-shaped pipes 18.
[0023] In this embodiment: the exhaust gas inside the shed 1 can be conveniently guided to the interior of the box 4 through the exhaust pipe 19, U-shaped pipe 18, conveying pipe 2, cavity 3 and horizontal pipe 12 by the suction fan 16. The filter screen 17 can conveniently filter the impurity particles in the exhaust gas and protect the suction fan 16.
[0024] As a technical optimization of this utility model, the second drainage cavity 13 and the first drainage cavity 14 are distributed vertically and horizontally.
[0025] In this embodiment, the second drainage cavity 13 and the first drainage cavity 14 are distributed vertically and horizontally, which helps the waste gas and the purification liquid to come into full contact.
[0026] As a technical optimization of this utility model, a liquid level gauge 20 is installed inside the collection box 7, and a drain pipe 10 is connected to the outer wall. A shut-off valve is installed on the outer wall of the drain pipe 10.
[0027] In this embodiment: the liquid level inside the collection tank 7 can be easily detected by the liquid level gauge 20, and the liquid inside the collection tank 7 can be easily discharged by the drain pipe 10.
[0028] As a technical optimization of this utility model, the outer wall of the storage box 6 is connected to a liquid inlet pipe.
[0029] In this embodiment, the purified liquid can be conveniently stored inside the storage tank 6 through the liquid inlet pipe.
[0030] As a technical optimization of this utility model, a controller is installed on the outer wall of the shed 1, and the level gauge 20, the shut-off valve, and the suction fan 16 are all electrically connected to the controller.
[0031] In this embodiment, the level gauge 20, the shut-off valve, and the suction fan 16 are all electrically connected to the controller, which allows for convenient control of the operation of each component.
[0032] Working principle: During use, the purified liquid is stored inside the storage tank 6 through the inlet pipe. The pump of the first drainage pipe 8 is started by the controller, and the purified liquid inside the storage tank 6 is transported to the first drainage chamber 14 connected to it through the first drainage pipe 8. It is then sprayed out through the nozzle at the lower end of the first drainage chamber 14. At this time, the exhaust gas inside the shed 1 can be easily guided by the suction fan 16 through the exhaust pipe 19, U-shaped pipe 18, conveying pipe 2, cavity 3 and horizontal pipe 12 to the inside of the box 4, and then through the first drainage chamber 14. The purification liquid sprayed from the nozzle can easily perform primary purification of the exhaust gas. After passing through the box 4, the liquid flows into the collection box 7 through the vertical pipe 11 (since some of the purification liquid does not fully contact the exhaust gas and does not fully react, the purification liquid can be reused to save costs). The controller sets a value for the level gauge 20. When the liquid level inside the collection box 7 reaches the set value, the controller opens the shut-off valve on the outer wall of the drain pipe 10 to discharge the excess liquid, so that the liquid level inside the collection box 7 remains constant.
[0033] Activating the liquid pump on the outer wall of the second drainage pipe 9 allows the liquid inside the collection box 7 to be easily guided through the second drainage pipe 9 to the inside of the second drainage cavity 13, and then sprayed out through the nozzle to perform secondary purification of the exhaust gas. Finally, the exhaust gas undergoes tertiary purification through the activated carbon filter 21 inside the exhaust pipe 5, thereby improving the overall purification effect.
[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
