Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a device for collecting and treating odors from pig farms. Background Technology

[0002] With the large-scale development of animal husbandry, especially intensive pig farms, a large amount of foul-smelling gases, such as ammonia, hydrogen sulfide, and other volatile organic compounds, are generated. These odors not only seriously pollute the surrounding atmospheric environment but also pose a threat to the health of farmers and nearby residents.

[0003] Currently, pig farms commonly use mechanical ventilation systems to remove odors from the pigsty. However, this method mostly just transfers the odor from inside the pigsty to outside, and the odor spreads haphazardly around the farm after being expelled, without being effectively collected and treated. This results in dispersed odor sources, making centralized treatment difficult and leading to low overall treatment efficiency.

[0004] To address this issue, some treatment devices have emerged in existing technologies, such as simple water scrubbing towers or single activated carbon adsorption. However, the composition of odor from pig farms is very complex, containing both water-soluble ammonia and persistent volatile organic compounds. Single treatment methods often have technological limitations, failing to efficiently remove multiple pollutants simultaneously, resulting in incomplete purification and difficulty in achieving stable emissions compliance.

[0005] In summary, the existing technology lacks an integrated device that can efficiently and securely collect scattered odor sources in pigsties and perform multi-stage, in-depth purification of complex odor components, resulting in incomplete odor collection and substandard treatment.

[0006] Therefore, this utility model proposes a pig farm odor collection and treatment device to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems of insufficient odor collection, incomplete purification process, low purification efficiency, and easy dissipation of odor in existing pig farm odor collection and treatment devices, this utility model aims to provide a pig farm odor collection and treatment device with improved structure that can effectively solve the above problems.

[0008] This utility model provides a device for collecting and treating odors in pig farms, including: an exhaust fan installed on the wall of the pig farm, an odor collection and conveying system, and an odor treatment system.

[0009] The odor collection and delivery system includes dust bags, converters, inclined pipes, PE corrugated pipes, blowers, and odor delivery pipes.

[0010] Wherein, one end of the dustproof bag is wrapped around the outlet end of the exhaust fan, the other end of the dustproof bag is connected to the conversion head, the other end of the conversion head is connected to the inclined pipe, the other end of the inclined pipe is connected to the middle end of the PE corrugated pipe, one end of the PE corrugated pipe is connected to the blower, and the other end is connected to the odor conveying pipe.

[0011] The odor treatment system includes an odor treatment box, which is vertically arranged from bottom to top with an aeration device, a water layer, an odor-deodorizing microbial treatment layer and an activated carbon layer.

[0012] The odor delivery pipe is connected to the aeration device.

[0013] Preferably, the odor treatment box has an exhaust vent on the top of its outer shell.

[0014] Preferably, the odor collection and treatment device for pig farms further includes clamps, the dustproof bag is fixed to the outlet end of the exhaust fan by the clamps, and the other end of the dustproof bag is fixedly connected to the converter head by another clamp.

[0015] Preferably, a check valve is installed inside the converter head.

[0016] Preferably, the aeration device includes an aeration main pipe and an aeration head.

[0017] Preferably, as a specific implementation, the connection between the odor delivery pipe and the aeration device is specifically that the odor delivery pipe is connected to the main aeration pipe.

[0018] Preferably, the deodorizing microbial treatment layer includes a honeycomb-shaped circular carrier arranged in multiple vertical layers, which serves as the implantation layer for deodorizing microorganisms. The microorganisms that attach to the carrier can decompose and treat the odor.

[0019] Preferably, the water layer is provided with an inlet pipe and an outlet pipe.

[0020] Preferably, the aeration head is located at the bottom of the odor treatment box.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up an odor collection and conveying system consisting of an exhaust fan, a dustproof bag, a converter, an inclined pipe, a PE corrugated pipe, a blower, and an odor conveying pipe, the problem of low odor collection efficiency and easy disorderly diffusion of odor in pig farms in the prior art is solved, and the technical effect of efficient centralized collection of odor in pig houses and prevention of odor leakage is achieved.

[0023] 2. In this utility model, the odor treatment system uses an aeration device, a water layer, a deodorizing microbial treatment layer, and an activated carbon layer arranged vertically from bottom to top in the odor treatment box. The odor is purified through a three-stage vertical purification structure of aeration and washing in the water layer, decomposition in the deodorizing microbial treatment layer, and adsorption by activated carbon. This achieves deep purification of complex odor components, with good treatment effect, and is suitable for efficient deodorization and purification in pig farms.

[0024] 3.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please refer to Figures 1 to 5 This utility model provides a pig farm odor collection and treatment device, which aims to solve the problems of insufficient odor collection, incomplete purification process leading to odor escape and low purification efficiency in the prior art.

[0034] like Figure 1 As shown, the odor collection and treatment device for pig farms includes an odor collection and conveying system installed in the pigsty and an odor treatment system for purifying the odor. This device is suitable for pig farms with positive pressure ventilation.

[0035] The device includes an exhaust fan 2 installed on the wall 1 of the pigsty, as well as an odor collection and conveying system and an odor treatment system. The exhaust fan 2 is a positive pressure fan. The odor treatment system includes an odor treatment box 11. The odor collection and conveying system includes a dustproof bag 4, a converter 5, an inclined pipe 6, a PE corrugated pipe 7, a blower 8, and an odor conveying pipe 16. One end of the dustproof bag 4 is wrapped around the outlet end of the exhaust fan 2. The other end of the dustproof bag 4 is connected to the converter 5. The other end of the converter 5 is connected to the inclined pipe 6. The other end of the inclined pipe 6 is connected to the middle of the PE corrugated pipe 7. One end of the PE corrugated pipe 7 is connected to the blower 8, and the other end is connected to the odor conveying pipe 16.

[0036] like Figure 1 , Figure 3 and Figure 5 As shown, the odor treatment box 11 is vertically arranged from bottom to top as an aeration device 15, a water layer 19, a deodorizing microbial treatment layer 13 and an activated carbon layer 12, as well as an exhaust port 18 located on the top of the outer shell of the odor treatment box 11.

[0037] The odor delivery pipe 16 is connected to the aeration device 15 at the bottom of the odor treatment box 11.

[0038] When there are multiple exhaust fans 2 in the pigsty, each exhaust fan 2 is connected to the PE corrugated pipe 7 through a dustproof bag 4, a converter 5, and an inclined pipe 6, so that the odorous gas discharged from the exhaust fan 2 can be collected into the odor delivery pipe 16, and finally enter the odor treatment box 11 to be deodorized and purified before being discharged through the exhaust port 18.

[0039] To solve the above-mentioned technical problems, the core of the technical solution in this embodiment lies in the fact that, through the structural cooperation of multiple specific components, a complete function from collection, backflow prevention, pressurization to multi-stage purification is achieved.

[0040] Please refer to the following carefully. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The core structure will be described in detail below:

[0041] Firstly, regarding the fixing and backflow prevention of the collection system, the device includes clamps 3 and check valves 17. Clamps 3 are used to securely connect the two ends of the dust bag 4. Specifically, the dust bag 4 is fixed to the outlet end of the exhaust fan 2 by clamps 3, and the other end of the dust bag 4 is fixedly connected to the converter 5 by another clamp 3. The check valve 17 is installed inside the converter 5 to prevent the backflow of odorous gases.

[0042] Secondly, in terms of odor delivery, the blower 8 is connected to the end of the PE corrugated pipe 7. This setting is used to pressurize and blow the odor collected at the front end, so that the odor can quickly enter the odor delivery pipe 16 and the odor treatment box 11.

[0043] Furthermore, regarding the internal structure of the odor treatment box 11, the odor treatment box 11 is vertically arranged from bottom to top as follows: an aeration device 15, a water layer 19, a deodorizing microbial treatment layer 13, and an activated carbon layer 12. The exterior of the odor treatment box 11 is a stainless steel shell, which encloses the internal structure. The shell effectively prevents the leakage of unpurified odor. An exhaust port 18 is also provided at the top of the shell, allowing the gas purified through multiple stages to be discharged. Specifically, the aeration device 15 includes an aeration main pipe 14 and an aeration head 20. The odor delivery pipe 16 is connected to the aeration main pipe 14. The aeration head 20 is located at the bottom of the odor treatment box 11 and contacts the water in the water layer 19. This structure allows the odor to be aerated at the bottom of the odor treatment box 11 through the aeration head 20. The aerated odor enters the water layer 19, where aerobic microorganisms are added to the water. These microorganisms can decompose ammonia and other gaseous substances or malodorous organic matter that can be decomposed by microorganisms. The space between the bottom of the odor treatment chamber 11 and the deodorizing microbial treatment layer 13 is a water layer 19. The deodorizing microbial treatment layer 13 above the water layer 19 is a deodorizing microbial implantation layer with a specific structure. It includes a vertically multi-layered honeycomb PP material circular carrier. The carrier is fixedly connected to the inner wall of the odor treatment chamber 11, which facilitates the implantation of deodorizing microorganisms on the carrier. The odorous gas treated by the water layer 19 enters the deodorizing microbial treatment layer 13 and is further decomposed by the microorganisms attached to it. The odorous gas treated by the deodorizing microbial treatment layer 13 then enters the activated carbon layer 12 above it. The activated carbon layer 12 is made by embedding activated carbon in a stainless steel mesh (200 mesh) and fixing it to the inner wall of the odor treatment chamber 11. The activated carbon in the activated carbon layer 12 further adsorbs and treats the harmful odorous gases in the odorous gas. Finally, the gas after multi-stage purification is discharged from the exhaust port 18 at the top of the odor treatment chamber 11.

[0044] The water layer 19 is also equipped with an inlet pipe 10 and an outlet pipe 9. The inlet pipe 10 and the outlet pipe 9 are used to replace the treated water in the water layer 19: specifically, the inlet pipe 10 is used to replenish the water layer 19 with clean water containing aerobic microorganisms, while the outlet pipe 9 is used to discharge the sewage in the water layer 19.

[0045] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0046] In a preferred embodiment, to improve the strength and sealing of the connection, the device also includes a clamp 3, the dust bag 4 is fixed to the outlet end of the exhaust fan 2 by the clamp 3, and the other end of the dust bag 4 is fixedly connected to the converter 5 by another clamp 3;

[0047] As another preferred embodiment, in order to prevent the odor from flowing back into the pigsty, a check valve 17 is installed inside the converter head 5;

[0048] As another preferred embodiment, in order to achieve uniform air distribution, the aeration device 15 includes an aeration main pipe 14 and an aeration head 20. The aeration device 15 can promote the full mixing of odor and water layer 19 and improve the deodorization and decomposition effect of microorganisms. On the other hand, it can provide power support for the upward flow of odor in the odor treatment box 11.

[0049] Based on the aeration device 15 including the aeration main pipe 14, as a more preferred embodiment, the connection between the odor delivery pipe 16 and the aeration device 15 is specifically that the odor delivery pipe 16 is connected to the aeration main pipe 14.

[0050] As another preferred embodiment, in order to increase the microbial attachment area and improve the treatment efficiency, the deodorizing microbial treatment layer 13 includes a honeycomb PP material circular carrier arranged in multiple vertical layers, on which microorganisms capable of treating odors are attached and attached.

[0051] In another preferred embodiment, in order to maintain the water level and water quality balance of the water layer 19, the water layer 19 is also connected to the inlet pipe 10 and the outlet pipe 9.

[0052] As another preferred embodiment, in order to clarify the installation location of the booster unit, a blower 8 is connected to the end of the PE bellows 7.

[0053] As another preferred embodiment, the aeration head 20 is located at the bottom of the odor treatment box 11.

[0054] The working principle of this utility model's odor collection and treatment device for pig farms is as follows:

[0055] When the exhaust fan 2 is started, the odor in the pigsty is extracted. The odor first passes through the dustproof bag 4 wrapped around the outlet of the exhaust fan 2. The dustproof bag 4 is fixed by the clamp 3 to transport the gas. Then the gas enters the converter head 5. The check valve 17 inside the converter head 5 ensures unidirectional airflow and prevents the odor from flowing back into the pigsty. The gas then passes through the inclined pipe 6 and is collected in the PE corrugated pipe 7. The blower 8 at the end of the PE corrugated pipe 7 then operates, pressurizing the collected odor and forcibly pumping it into the odor treatment box 11 through the odor delivery pipe 16. Inside the odor treatment box 11, the odor transported by the odor delivery pipe 16 reaches the aeration main pipe 14 and is aerated from the aeration head 20 located at the bottom of the odor treatment box 11. The aerated odor is decomposed by microorganisms in the water layer 19, achieving the first stage of biological water washing purification. The gas continues to rise, passing sequentially through the vertically arranged deodorizing microbial treatment layer 13 and activated carbon layer 12 from bottom to top. On the vertically arranged multi-layered honeycomb PP material circular carriers in the deodorizing microbial treatment layer 13, microorganisms that can decompose odors are attached and perform a second-stage decomposition treatment of the odor. The gas continues to rise to the activated carbon layer 12, where the activated carbon performs a third-stage physical adsorption of the odor, achieving a three-stage purification. Finally, the purified gas is discharged from the exhaust port 18 at the top of the odor treatment box 11, realizing the collection and three-stage purification of odors in pig farms with positive pressure ventilation, which is particularly suitable for pig farms.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
