Description

Technical Field

[0001] This invention relates to the field of deodorization system technology, specifically to a deodorization system and method for poultry houses. Background Technology

[0002] Although there are many patents in China for odor control in livestock and poultry houses, most of them focus on pig house deodorization, with few cases or patents specifically for chicken house deodorization. With the promotion and application of high-efficiency intensive chicken houses, the scale of single chicken houses has increased significantly, reaching 40,000 to 100,000 birds per house, making chicken house odor control an important target. Due to the physiological differences between chickens and pigs, the focus of chicken house deodorization is completely different from that of pig houses. Chicken manure in high-efficiency chicken houses is usually produced and disposed of daily, and the odor concentration is relatively low. Therefore, the focus of odor control in chicken houses should first be on dust reduction and feather separation, and then on deodorization. In addition, chickens are more prone to heatstroke than pigs, and chicken houses require a larger ventilation volume. This means that the ventilation effect must be ensured during the deodorization process. If the deodorization device is not designed properly, it may lead to serious production safety problems. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a deodorization system and method for poultry houses. This solves the problem that chicken manure in high-efficiency chicken houses is usually produced and disposed of daily, resulting in relatively low odor concentrations. Therefore, odor control in chicken houses should first focus on dust reduction and feather separation, and only secondly on deodorization.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a deodorization system and method for poultry houses, comprising a poultry house, an internal fan fixedly installed inside the poultry house, a dust-reducing and deodorizing chamber on the outer wall of the poultry house, a translucent PVC rainproof panel fixed to the top of the dust-reducing and deodorizing chamber, side-openable filler walls connected to the front and sides of the dust-reducing and deodorizing chamber, and front filler walls connected to the front and sides of the dust-reducing and deodorizing chamber. The dust-reducing and deodorizing chamber is used to reduce dust, deodorize, and block feathers in the air discharged from the poultry house. Multiple atomizing systems are arranged on the longitudinal surface of the dust-reducing and deodorizing chamber. Each atomizing system includes an atomizing nozzle, a filtration system, an atomizing pump, and a water tank. The atomizing system sprays atomized liquid to increase the weight of dust and feathers for dust reduction and feather blocking. The filtration system is a security filter or a bag filter.

[0005] Preferably, the top of the dust suppression and deodorization room is connected to a flow guiding structure that is high in the middle and low on both sides, so as to quickly guide away rainwater from the roof.

[0006] Preferably, the outer wall of the dust reduction and deodorization room is connected to a maintenance door.

[0007] Preferably, the atomizing pump and water bucket are fixed inside the poultry house, and the water is treated by a security guard or bag filter before spraying.

[0008] Preferably, a baffle is connected between the dust suppression and deodorization chamber and the front filler wall to intercept larger feathers.

[0009] Preferably, both the side-openable packing wall and the bottom of the front packing wall are provided with multi-stage circulating water tanks. The multi-stage circulating water tanks are connected to the packing wall through spiral nozzles and spray pipes, which are used to evenly spray the deodorizing liquid onto the surface and inside of the packing wall.

[0010] Preferably, the bottom of the front filler wall is provided with a water receiving trough made of polypropylene, and a guide plate is fixed above the water receiving trough for recovering the spray liquid blown out from the front filler wall.

[0011] Preferably, the side-switchable packing wall is a switchable movable packing wall used for emergency ventilation in extreme high-temperature weather. The bottom of the side-switchable packing wall is provided with a polypropylene water receiving tank, and a guide plate is fixed above the polypropylene water receiving tank for recovering the spray liquid blown out from the side-switchable packing wall.

[0012] Preferably, the multi-stage circulating water tank consists of multiple interconnected small tanks connected by a water tank connecting pipe. The last stage of the multi-stage circulating water tank is equipped with a circulating spray pump to provide circulating spray water for the spray system of the side-openable filler wall and the front filler wall.

[0013] A method for deodorizing poultry houses, the method comprising the following steps:

[0014] Start the atomization system: By activating the atomizing nozzles set 20 cm in front of the fan, clean water or water with added deodorizer after being filtered is sprayed into a fine mist, which increases the weight of dust and feathers in the air, thereby achieving initial dust reduction and feather blocking.

[0015] Start the spray system: Turn on the spiral nozzles and spray pipes in front of the side switchable packing wall and the front packing wall located in the dust reduction and deodorization room to evenly spray the deodorizing liquid in the multi-stage circulating water tank onto the surface of the packing wall, realize gas-liquid exchange, and thus efficiently deodorize the air passing through the packing wall.

[0016] Large feathers are intercepted by the baffle: Larger feathers and debris are intercepted by the baffle located between the fan and the front packing wall of the dust suppression and deodorization chamber, preventing them from entering the packing wall and causing blockage.

[0017] Collect and circulate the spray liquid: Wastewater generated by the spray liquid is collected through polypropylene water collection tanks located at the bottom of the side switchable packing wall and the front packing wall, and the water is circulated using multi-stage sedimentation tanks and circulating spray pumps.

[0018] Rainwater drainage from the roof: The PVC rainproof board at the top of the dust suppression and deodorization room is used to drain the rainwater from the roof in a timely manner, preventing water from entering the deodorization system and affecting the deodorization effect and the working efficiency of the filling wall.

[0019] Handling extreme heat weather: In the event of extreme heat weather, the side-openable filler wall can be opened to enhance air circulation and prevent chickens in the poultry house from suffering heatstroke. At the same time, the spray liquid can be collected and recycled through the water collection trough and guide plate at the bottom of the filler wall.

[0020] Regularly replace the spraying solution: Replace the spraying solution regularly through the drain and water supply outlets at the bottom of the multi-stage circulating water tank, and transport the wastewater to the on-site wastewater treatment station for treatment before reuse.

[0021] This invention provides a deodorization system and method for poultry houses. It has the following beneficial effects:

[0022] 1. This invention adopts a rainproof design on the top of the dust suppression and deodorization room, which effectively prevents a large amount of rainwater from entering the dust suppression and deodorization room on rainy days. This avoids the rainwater from turning into sewage and entering the wastewater station, thereby increasing the load on wastewater treatment and reducing the pressure on wastewater treatment from the source.

[0023] 2. The dust reduction and deodorization chamber of this invention has a filler wall structure on the front and both sides, which increases the ventilation gap. The filler walls on both sides are designed to be openable, which provides an important safety emergency measure to deal with heatstroke in chickens during extreme high temperature weather. While achieving dust reduction and deodorization, it ensures the safety and stability of chicken house production.

[0024] 3. This invention achieves efficient dust reduction and feather prevention through spraying at the fan end and using a screen; it increases the gas-liquid exchange area by using a packing wall and continuously circulates deodorizing liquid through spiral nozzles, thus achieving efficient treatment of odor in poultry houses (chicken houses). Since this dust reduction and deodorization room only requires regular cleaning of chicken feathers in the screen, no other complicated maintenance work is required, which greatly reduces the workload and has good promotion and application value.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see the appendix Figure 1 - Appendix Figure 4 This invention provides a deodorization system and method for poultry houses, including a poultry house 1. A fan 2, which is a negative pressure fan, is fixed inside the poultry house 1. A dust-reducing and deodorizing chamber 4 is located on the outer wall of the poultry house 1. A translucent PVC rainproof panel 6 is fixed to the top of the dust-reducing and deodorizing chamber 4. Side-openable filler walls 7 are connected to both sides of the dust-reducing and deodorizing chamber 4, and a front filler wall 8 is connected to the front of the dust-reducing and deodorizing chamber 4. The dust-reducing and deodorizing chamber 4 is used to reduce dust and deodorize the air discharged from the poultry house 1. The dust-suppressing and deodorizing chamber 4 is equipped with multiple atomizing systems on its longitudinal surface. The atomizing system includes atomizing nozzles 3, a filtration system 18, an atomizing pump 9, and a water tank 19. The atomizing system is used to spray atomized liquid to increase the weight of dust and feathers, thereby suppressing dust and blocking feathers. The filtration system 18 is a security or bag filter. The top of the dust-suppressing and deodorizing chamber 4 is connected to a flow guide structure that is high in the middle and low on both sides to quickly guide away rainwater from the roof. The outer wall of the dust-suppressing and deodorizing chamber 4 is connected to a maintenance door 14.

[0033] Specifically, the dust suppression and deodorization chamber 4 is located on the outer wall of poultry house 1. The floor of the dust suppression and deodorization chamber 4 has been hardened to withstand wear and contamination during long-term use. Drainage ditches or rainwater ditches are installed around the chamber, connecting to the rainwater ditch of poultry house 1, ensuring that the dust suppression and deodorization chamber 4 will not be affected by water accumulation during rainy days. The top is covered with a rainproof and light-transmitting PVC rainproof panel 6, which has good corrosion resistance and light transmission, preventing rainwater from entering the dust suppression and deodorization chamber 4 while providing natural light to the interior, helping to maintain the system's operational stability. A 25 cm thick front packing wall 8 is installed on the front of the dust suppression and deodorization chamber 4, providing sufficient surface area for gas-liquid exchange to achieve efficient deodorization. The sides are equipped with 20 cm thick switchable side packing walls 7. This design not only increases ventilation gaps but also facilitates full ventilation during normal operation. The ventilation system can be activated during extreme heat to address emergencies such as heatstroke in chickens and other poultry, providing necessary safety and emergency measures. The width of the dust suppression and deodorization chamber 4 is designed to be 8-10 meters from the end of the fan 2 to ensure sufficient airflow contact time and space. Its length is the same as the width of the poultry house 1, ensuring that all exhaust air from the poultry house can be treated by the dust suppression and deodorization chamber 4. Through multiple functions of dust suppression, deodorization, and feather blocking, it effectively improves the air quality of the poultry house 1 and reduces odor emissions to the surrounding environment, achieving a dual improvement in environmental protection and economic benefits. The top of the dust suppression and deodorization chamber 4 adopts a guide structure that is high in the middle and low on both sides or high on one side and low on the other side, which can effectively guide and quickly drain rainwater from the roof, preventing rainwater accumulation from affecting the internal function of the dust suppression and deodorization chamber 4. This design is more waterproof and easier to maintain than the simple flat roof structure of the existing technology.

[0034] The atomizing pump 9 and water tank 19 are fixed inside the poultry house 1. The water is treated by a security guard or bag filter before being sprayed.

[0035] A baffle 5 is connected between the dust suppression and deodorization chamber 4 and the front filler wall 8 to intercept larger feathers.

[0036] Both the side-openable packing wall 7 and the front packing wall 8 are equipped with multi-stage circulating water tanks 10 at their bottom. The multi-stage circulating water tanks 10 are connected to the packing wall through spiral nozzles and spray pipes 12, which are used to evenly spray the deodorizing liquid onto the surface and inside of the packing wall.

[0037] Specifically, multiple atomizing systems are installed on the longitudinal surface of the dust suppression and deodorization room 4, located 20 cm from the end of the fan 2. Each atomizing system includes atomizing nozzles 3, a filtration system 18, an atomizing pump 9, and a water tank 19. The atomizing nozzles 3 have small outlet diameters, enabling them to fully atomize the liquid (the atomized droplets are approximately 60 μm in diameter). The atomizing pump 9 and water tank 19 are installed inside the poultry house 1 or outside the dust suppression and deodorization room 4. The water is treated by a security or bag filter in the filtration system 18 to ensure the cleanliness of the sprayed atomized liquid and effectively increase dust concentration. By reducing the weight of dust and feathers, this design achieves efficient dust removal and feather blocking. Compared with traditional deodorization equipment, this design ensures the cleanliness of the spray medium by introducing a filtration system 18, effectively avoiding the problem of nozzle clogging. At the same time, the atomization process increases the settling speed of dust and feathers in the air, significantly enhancing dust removal efficiency and deodorization effect, greatly reducing the degree of air pollution inside and outside the poultry house, and enabling the system to maintain high efficiency and stable performance during continuous operation. This further highlights the significant advantages of existing technologies in dust removal, feather blocking, and ease of maintenance.

[0038] The bottom of the front filler wall 8 is provided with a polypropylene water receiving trough 16, and a guide plate 17 is fixed above the water receiving trough 16 to recover the spray liquid blown out from the front filler wall 8.

[0039] The side-openable packing wall 7 is a movable packing wall that can be opened and closed, used for emergency ventilation in extreme high temperature weather. The bottom of the side-openable packing wall 7 is provided with a polypropylene water receiving tank 13, and a guide plate 17 is fixed above the polypropylene water receiving tank 13 for recovering the spray liquid blown out from the side-openable packing wall 7.

[0040] The multi-stage circulating water tank 10 consists of multiple interconnected small tanks connected by a water tank connecting pipe 15. The last stage of the multi-stage circulating water tank 10 is equipped with a circulating spray pump 11, which is used to provide circulating spray water for the spray system of the side switchable packing wall 7 and the front packing wall 8.

[0041] Specifically, a 1×1 cm mesh screen 5 is installed approximately 6 meters away from the blower 2 and the front packing wall 8 of the dust suppression and deodorization chamber 4. This screen is used to intercept larger feathers, effectively reducing clogging of the rear front packing wall 8, extending its service life, and reducing maintenance frequency. The front packing wall 8 and the side switchable packing wall 7 of the dust suppression and deodorization chamber 4 are 25 cm and 20 cm thick, respectively. A multi-stage circulating water tank 10 is installed at the bottom of the packing wall. The multi-stage circulating water tank 10 is connected to the spiral nozzles and spray pipes 12 in front of the packing wall, which evenly spray the deodorizing liquid onto the surface of the packing wall, achieving efficient deodorization through gas-liquid exchange. The bottom of the front packing wall 8 is equipped with a polypropylene water receiving trough. The length of the trough is the same as the width of the poultry house, the width is 1.5 meters, and the height is 0.5 meters. A 30 cm wide guide plate 17 extends from the top at a 45° angle to collect the spray liquid blown out from the front packing wall 8, avoiding resource waste and further optimizing the recycling efficiency. The side-mounted switchable packing walls 7 are designed as movable structures, which can be opened as needed to meet emergency ventilation requirements during extreme high-temperature weather. At their bottom are polypropylene water collection troughs 13, 1 meter wide and 0.1 meters high, and equipped with 45° inclined 30cm guide plates 17, also used for recycling spray liquid. The multi-stage circulating water tank 10 beneath the side-mounted switchable packing walls 7 and the front packing wall 8 in the dust suppression and deodorization room 4 consists of multiple interconnected small tanks. The connecting ports between the tanks are staggered and connected by water tank connecting pipes 15 to enhance the stability of the water flow. A circulating spray pump 11 is installed in the last stage of the multi-stage circulating water tank 10 to ensure a continuous circulating spray water supply for the spray systems of the side-mounted switchable packing walls 7 and the front packing wall 8. Compared to existing technologies, this design not only significantly improves deodorization efficiency, but also greatly reduces operating costs and maintenance frequency through a precise liquid recovery and circulation system. At the same time, it ensures ventilation and cooling of poultry houses in high-temperature environments, thus ensuring the safety and stability of production. This highlights the significant advantages of this invention in deodorization efficiency, energy saving and environmental protection, and ease of operation.

[0042] Example 2

[0043] Please see the appendix Figure 1 - Appendix Figure 4 This invention provides a deodorization method for poultry houses, which includes the following steps:

[0044] Activate the atomization system: By activating the atomizing nozzles 3 located 20 cm in front of the fan 2, the treated water or water with added deodorizer, filtered by the filtration system 18, is sprayed into a fine mist, increasing the weight of dust and feathers in the air, thus achieving initial dust reduction and feather interception; Activate the spray system: By opening the spiral nozzles and spray pipes 12 located in front of the side-operated switchable packing wall 7 and the front packing wall 8 in the dust reduction and deodorization chamber 4, the deodorizing liquid in the multi-stage circulating water tank 10 is evenly sprayed onto the surface of the packing wall, achieving gas-liquid exchange, thereby efficiently deodorizing the air passing through the packing wall; Operate the baffle 5 to intercept large feathers: The baffle 5 located between the fan 2 and the front packing wall 8 of the dust reduction and deodorization chamber 4 intercepts larger feather and debris particles, preventing them from entering the packing wall and causing blockage; Collect and circulate the spray liquid: The side-operated switchable... The polypropylene water collection trough 13 at the bottom of the packing wall 7 and the front packing wall 8 collects the wastewater formed by the spray liquid, and uses a multi-stage sedimentation tank and a circulating spray pump 11 to circulate the water; Rainwater from the roof is diverted: the PVC rainproof board 6 at the top of the dust suppression and deodorization room 4 diverts the accumulated water from the roof in a timely manner, preventing water from entering the deodorization system and affecting the deodorization effect and the working efficiency of the packing wall; Handling extreme high temperature weather: in the event of extreme high temperature weather, the side-openable packing wall 7 can be opened to enhance air circulation and prevent chickens in the poultry house 1 from suffering heatstroke. At the same time, the spray liquid is collected and recovered through the water collection trough 16 and the guide plate 17 at the bottom of the packing wall; Regular replacement of spray liquid: the spray liquid is replaced regularly through the drain outlet and water supply outlet at the bottom of the multi-stage circulating water tank 10, and the wastewater is transported to the on-site wastewater treatment station for treatment before reuse.

[0045] Specifically, firstly, the atomization system is activated. By activating the atomizing nozzles 3, located 20 cm in front of the fan 2, clean water treated by the filtration system 18 or water with added deodorizer is sprayed into a fine mist, increasing the weight of dust and feathers in the air, thus achieving initial dust reduction and feather interception. Compared to the single deodorization method in existing technologies, this design improves the settling efficiency of dust and feathers through atomization. Secondly, the spray system is activated. The spiral nozzles and spray pipes 12 located in front of the side-operated switchable packing wall 7 and the front packing wall 8 in the dust reduction and deodorization chamber 4 are opened, and the deodorizing liquid in the multi-stage circulating water tank 10 is evenly sprayed onto the surface of the packing wall, achieving gas-liquid exchange, thereby efficiently deodorizing the air passing through the packing wall. Compared with traditional deodorization equipment, this... The spray system significantly improves odor treatment efficiency by increasing the gas-liquid contact area. Furthermore, the baffle 5 intercepts large feathers. Located between the fan 2 and the front packing wall 8 of the dust suppression and deodorization chamber 4, the baffle 5 intercepts larger feather and debris particles, preventing them from entering the packing wall and causing blockage, thus improving system operating efficiency. This design effectively solves the problem of easy clogging of packing walls in existing technologies and extends the equipment maintenance cycle. Next, the spray liquid is collected and circulated. Wastewater formed by the spray liquid is collected through the polypropylene water collection tank 13 located at the bottom of the side switchable packing wall 7 and the front packing wall 8. The water is then circulated using a multi-stage sedimentation tank and a circulating spray pump 11 to ensure the continuous and efficient operation of the system. This recycling design not only… This design reduces water consumption and offers significant advantages in operating costs. Furthermore, it diverts rainwater from the roof via a PVC rainproof board 6 at the top of the dust suppression and deodorization room 4, ensuring timely drainage and preventing water from entering the deodorization system and affecting its deodorization effect and the efficiency of the packing wall. This design offers better protection compared to traditional equipment top designs, further improving system stability. In extreme heat, the side-operated switchable packing wall 7 can be opened to enhance air circulation and prevent heatstroke in the poultry house 1. Simultaneously, the spray liquid is collected and recycled through the water collection trough and guide plate 17 at the bottom of the packing wall. This emergency ventilation design significantly enhances the system's safety and adaptability. Finally, the spray liquid is replaced regularly via a multi-stage circulating water tank 10. The drainage and water supply outlets are designed to regularly replace the spraying liquid, and wastewater is transported to the on-site wastewater treatment plant for treatment before reuse to maintain the cleanliness and effectiveness of the deodorizing liquid. This design ensures the system's high efficiency and environmental friendliness during long-term operation, reducing reliance on chemical agents compared to existing technologies and further improving environmental performance. Overall, the deodorization method provided by this invention significantly improves deodorization efficiency, ease of operation, and operational stability through multiple improvements, demonstrating clear innovative advantages and practical value compared to existing technologies. Both the side and front packing walls are made of porous packing material, allowing gas to pass directly through the porous packing only after exchanging with the deodorizing liquid. The spraying water in the circulating water tank can only be recycled within a certain time frame, requiring water replacement every 7-10 days.In fact, the exhaust fan also removes a lot of moisture. This pool needs to be replenished daily using an automatic float system based on the water level. Drainage and spraying are powered by centrifugal pumps. These pumps are located in the middle pool of the front packing layer, connected to it by pipes. The centrifugal pumps cannot be submerged; they are located outside the pool, inside the dust settling room. They provide power for both spraying and drainage. The pumps are connected to a three-way valve. One valve draws water from the pool through the pipes to the spray pipes of the three packing layers for spraying. The other valve is a drain valve; closing the spray valve and opening the drain valve allows drainage directly into the sedimentation well at the end of the chicken coop, from where it flows through the wastewater network to the wastewater treatment plant.
