Description

Technical Field

[0001] The invention relates to the technical field of livestock breeding equipment, and in particular to a pig house terminal deodorizing device based on nano mineral crystal agents. Background Art

[0002] At present, with the continuous improvement of the scale and intensive level of the breeding industry, ammonia (NH3), hydrogen sulfide (H2S) and volatile organic compounds (VOCs) and other harmful odorous gases generated during the fermentation and ventilation of manure in pig houses are released in large quantities, which seriously affects the quality of the breeding environment, not only posing a threat to the health of pigs, but also polluting the working environment of breeders and the surrounding ecological environment. Therefore, efficient deodorization of pig house exhaust has become an important technical problem that needs to be solved in modern farms.

[0003] Existing pig house deodorization devices are mostly based on single filter adsorption or liquid spraying. Although they can reduce odor emissions to a certain extent, they often have defects such as low purification efficiency, limited treatment types, and unstable system operation. On the one hand, the traditional filter structure is very easy to clog in a pig house environment with high dust and high humidity. Once the filter is covered with feces, dust, and hair, it will lead to increased wind resistance and reduced ventilation efficiency. Frequent replacement or cleaning will not only increase the operation and maintenance costs, but also affect the reliability of the continuous operation of the system. On the other hand, liquid deodorization devices have high requirements for gas residence time and reaction area. If they are not properly matched, there will be problems such as waste of reagents or incomplete deodorization.

[0004] In addition, the existing devices have a single function in structural design, and often one component only corresponds to one purpose, resulting in a large system size, low efficiency, and low resource utilization. For example, fans are usually only used to promote airflow and lack intelligent adjustment and self-maintenance functions; wet curtains and spray systems are arranged in a single way, making it difficult to achieve graded treatment for different odor components. This "equipment stacking" design method not only increases the burden on the system, but also limits its application in small-scale and intelligent farming scenarios.

[0005] To this end, we have provided a pig house terminal deodorization device based on nano-mineral crystal agents that has multiple functions such as multi-stage purification, automatic cleaning, and energy recovery to improve overall operating efficiency, extend equipment life, and reduce breeding pollution emissions. Summary of the invention

[0006] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a pig house terminal deodorization device based on nano-mineral crystal agents.

[0007] The object of the present invention is achieved in this way: A pigsty end deodorization device based on nano-mineral crystal agent, comprising a box body. An air inlet is arranged on the left side of the box body, and an air outlet is arranged on the right side of the box body. A filter screen is arranged inside the box body, and the filter screen is located on the left side inside the box body. A fan mechanism is arranged inside the box body on the right side of the filter screen, an adsorption filter screen is arranged inside the box body on the right side of the fan mechanism, and a liquid deodorization mechanism is arranged inside the box body on the right side of the adsorption filter screen.

[0008] Further, the liquid deodorization mechanism includes a first wet curtain, the first wet curtain is located inside the box body on the right side of the adsorption filter screen, a spraying mechanism is arranged on the box body on the right side of the first wet curtain, and a second wet curtain is arranged on the right side of the spraying mechanism.

[0009] Further, the spraying mechanism includes a first spraying pipeline and a second spraying pipeline, and the first spraying pipeline and the second spraying pipeline are respectively located in the upper part of the box body.

[0010] Further, the area inside the box body between the first wet curtain and the second wet curtain is a liquid deodorization bin. A drain pipe is arranged on the box body at the bottom of the liquid deodorization bin, and a first valve is arranged on the drain pipe. Opening the first valve can discharge the liquid drained by the liquid deodorization mechanism out of the box body through the drain pipe.

[0011] In this application, a multi-stage collaborative deodorization structure is adopted, and nano-mineral crystal agent is uniformly used: After the gas passes through solid adsorption (adsorption filter screen), it flows through the first wet curtain, the first spraying pipeline, the second spraying pipeline and the second wet curtain in sequence, forming a four-stage liquid deodorization path, and each stage of structure supplies liquid through nano-mineral crystal agent. Compared with the traditional single-stage treatment method, this scheme improves the sufficiency of contact between odor molecules and liquid agent and the reaction efficiency, and has a more comprehensive decomposition effect on various composite odor gases such as ammonia (NH3), hydrogen sulfide (H2S), and VOCs.

[0012] Fan reversible structure + one-way opening and closing valve, automatic reverse blowing to clean the filter screen: Set a reversible fan and a one-way opening and closing valve to realize the function of cleaning the filter screen by reverse air flow without disassembly and automation. Through the reverse blowing, impurities such as hair, dust, and feed residues adhered to the outside of the filter screen automatically fall off, solving the problems of blockage and difficult cleaning of the filter screen at the end of traditional pigsties.

[0013] Wind direction adjustment mechanism, realizing multi-angle precise reverse blowing and cleaning: Adopt a linkage type air deflector structure, and the reverse blowing direction of the fan can be adjusted directionally according to requirements. By moving the position of the air deflector, the wind force intensity can be locally enhanced, and fixed-point high-efficiency cleaning can be achieved for severely polluted areas, effectively improving the cleaning quality of the filter screen and extending the service life of the filter material.

[0014] Heat collection + heat dissipation structure realizes heat recovery and reuse: By setting up a collector - pipeline - radiator loop, it can absorb heat from high-temperature exhaust gas and transport the heat to the air inlet end of the pigsty or the water supply system through water circulation, achieving the recovery and reuse of energy. The air deflector can be opened / closed according to seasons or needs to flexibly control whether the air flow enters the heat collection area, avoiding unnecessary energy consumption.

[0015] Efficient deodorization, sterilization and dust removal in one: Utilizing the porous structure and catalytic characteristics of nano mineral crystal agents to achieve efficient adsorption and decomposition of common livestock and poultry malodorous gases. At the same time, accompanied by the release of a certain amount of water vapor, it helps to reduce the dust concentration in the pigsty, inhibit the spread of pathogenic microorganisms, and improve the animal health environment.

[0016] Self-cleaning filter screen, easy to maintain: The fan back-blowing structure cooperates with the air deflector to achieve fixed-point peeling of impurities on the filter screen surface, cleaning without tools and disassembly. It is especially suitable for the end treatment system of high-load and long-time operating farms, reducing the manual maintenance intensity and cost.

[0017] Heat energy recovery, energy saving and environmental protection: Recover the heat in the high-temperature exhaust gas and re-introduce it into the pigsty heating or water supply system. It is especially applicable in winter, which not only improves the energy utilization efficiency but also reduces the burden on external heating equipment, meeting the requirements of green breeding and low-carbon development.

[0018] The fan mechanism not only serves as a traditional air supply driving component, but also undertakes multiple key functions such as gas pushing, filter screen cleaning, and system commutation regulation through its flipable characteristics and cooperation with other structures; one fan structure realizes multiple functions, avoiding the additional installation of independent cleaning or air regulating equipment, making the system more compact and smaller in size. Reducing the number of components simplifies the control logic and reduces the manufacturing and operation and maintenance costs. Extend the filter screen life through the back-blowing cleaning function and reduce the probability of system failure caused by filter screen blockage. The fan can intelligently switch the operation mode by combining differential pressure sensing, time control, etc., facilitating future integration with the breeding environment monitoring system.

[0019] 1. Conventional air supply function, driving gas flow: In the normal working state of the device, the fan serves as the power source for gas transmission. Through its rotation, a stable air flow is formed, sucking the exhaust gas in the pigsty from the air inlet, and sending it to the air outlet after being treated by multiple purification units, completing the transportation and deodorization process of the pigsty exhaust gas.

[0020] 2. Reverse blowing function to achieve self-cleaning of the filter screen without disassembly: Through the fan steering structure (there are rotating shafts above and below the fan, and the bottom is controlled by a driving motor), the fan can rotate in the reverse direction to generate a reverse air flow. With the cooperation of the one-way opening and closing valve structure set on the right side of the fan, the reverse air flow will not be pushed towards the rear deodorization unit, but is released through the one-way valve to the left outlet, realizing reverse blowing of the filter screen from the inside to the outside. This design breaks through the bottleneck of traditional filter screens relying on manual disassembly and cleaning, effectively peeling off the attached dust and lint on the outside, and achieving lossless and automated cleaning and maintenance.

[0021] 3. Cooperate with the air guiding mechanism to adjust the cleaning air direction and improve the local cleaning efficiency: When the fan blows in the reverse direction, the gas flow direction can be controlled by the air direction adjustment mechanism (air deflector structure) at the front end. The air flow generated by the fan can be blown towards the filter screen at different angles under the guidance of the air deflector, achieving multi-angle and multi-position fixed-point cleaning. By adjusting the opening angle or quantity of the air deflector, the air flow speed can also be locally enhanced to clean severely blocked areas, improving the overall filter screen usage effect and system efficiency.

[0022] When this application is in use, when it is necessary to deodorize the gas discharged from the pigsty, the gas discharged from the pigsty enters the box through the air inlet on the left side of the box (by controlling the rotation of the fan to drive the gas to be inhaled into the box). When the gas enters the box through the air inlet plate at the air inlet, (the air inlet plate and the exhaust plate are breathable grille structures with a certain ventilation structure, which can block large suspended solids in the gas, etc.) the air inlet plate blocks the large suspended solids in the gas outside the box. After the gas enters the box, it passes through a filter screen. The filter screen is a structure that can filter fine floating dust in the gas. This is an existing technology and will not be described in technical details. It can achieve the filtration of impurities and dust in the gas. The filter screen filters the dust and impurities again. The gas then enters the middle of the box through the fan. The gas passes through the adsorption filter screen under the blowing of the fan. (The adsorption filter screen can filter and fix harmful gases. It adopts a multi-layer structure design. The first layer is a coconut shell activated carbon adsorption layer, which has a high specific surface area and mainly adsorbs small and medium-sized organic / inorganic odor gases such as VOC and H2S. The second layer is a modified zeolite molecular sieve layer, which has a strong ammonia selective adsorption ability and is suitable for high-concentration ammonia in farms. The third layer oxidizes and decomposes some sulfides to improve the treatment efficiency of H2S. Through the above structure, deep adsorption of ammonia (NH3), hydrogen sulfide (H2S), volatile organic compounds (VOCs), etc. contained in the preliminarily filtered gas is achieved.) The porous adsorption material of the adsorption filter screen fixes harmful gases through physical adsorption, chemical reactions, etc., extends the purification path and improves the treatment efficiency. The gas is then deodorized by the liquid deodorization mechanism. The liquid deodorization mechanism for pigsty gas includes four liquid deodorization units: wet curtain 1, spray pipe 1, spray pipe 2, and wet curtain 2. And a nano-mineral crystal agent is uniformly used as the deodorant supply source to form a multi-stage, continuous, and efficient gas-liquid contact deodorization system, which has the following technical effects and advantages:

[0023] Segmented multi-stage deodorization, purifying odor gas layer by layer: The gas adsorbed by the solid filter screen first passes through wet curtain 1, and the gas is first pre-treated through a large-area high-humidity environment to preliminarily dissolve water-soluble gases such as residual ammonia (NH3) and hydrogen sulfide (H2S) in the gas; then it is sprayed with nano-mineral crystal agents at high frequency through spray pipe 1 and spray pipe 2 to strengthen the contact reaction between the liquid medicine and the odor molecules; finally, the gas is settled through wet curtain 2 to further absorb the trace odor residues in the gas, realizing the comprehensive and multiple purification of the odor. (Nano-mineral crystals have a high specific surface area and a porous lattice structure, and can quickly adsorb and catalytically decompose various odor molecules; after adding the deodorant liquid, it can not only actively participate in the neutralization reaction of the odor as an effective component in the liquid, but also form an adsorption layer on the surface of the wet curtain, extending the gas-liquid reaction path and improving the deodorization efficiency. Traditional deodorant liquids have limited effects on non-water-soluble VOCs, etc., while the nano-mineral crystal agent is rich in metal oxides and silicon-aluminum skeletons, and has good dual capabilities of catalytic oxidation and physical adsorption, and can treat various composite gases such as ammonia, methyl mercaptan, and benzene series.) During the deodorization process, the system releases an appropriate amount of water vapor to adjust the air humidity in the pig house, effectively reducing the dust and bacteria concentration; in addition, the nano-mineral crystal agent also has a certain bacteriostatic effect, which can further reduce the irritation of ammonia to the respiratory tract of pigs, improve the breeding environment, and enhance the health level of livestock and poultry. The four-stage deodorization structure is supplied with liquid by a unified liquid medicine supply system, and the liquid medicine tank can be equipped with an automatic liquid supplement and concentration control device to ensure the stable operation of the spray and wet curtain systems, controllable deodorization effect, low maintenance cost, and convenient management.

[0024] The gas passing through the liquid deodorization mechanism is discharged outside the box through the air outlet, and the gas can be directly discharged outside the pig house, or the device can be directly used in the pig house to realize the purification and circulation of the gas in the pig house. When purifying the gas, due to the adoption of spray deodorization, there is a certain amount of moisture in the discharged gas, which can release an appropriate amount of water vapor to adjust the air humidity in the pig house, effectively reducing the dust and bacteria concentration; in addition, the nano-mineral crystal agent also has a certain bacteriostatic effect, which can further reduce the irritation of ammonia to the respiratory tract of pigs, improve the breeding environment, and enhance the health level of livestock and poultry.

[0025] Since the gas environment in the pigsty is relatively dirty, the filter screen needs to be frequently cleaned or replaced when filtering and purifying the gas. This application designs a reversible fan that can blow air in the reverse direction. This fan has the ability to adjust the air flow in both forward and reverse directions. Combined with the gas filter screen set at the front end, it can achieve effective ventilation and odor gas transmission under normal operating conditions, and realize the function of cleaning the filter screen with reverse air flow during the maintenance stage, thus bringing the following beneficial technical effects: 1. Realize the function of self-cleaning the filter screen without disassembly: By changing the working mode of the fan from normal air supply to reverse blowing, the dust, hair, feed debris and other impurities accumulated on the outer surface of the filter screen for a long time can be effectively stripped in the form of air flow, avoiding the influence on the ventilation efficiency due to pollutant blockage, reducing the maintenance frequency, and lowering the labor cost. 2. Prolong the service life of the filter screen and improve the operation stability: Traditional filter screens need to be manually disassembled and cleaned regularly, which is easy to cause physical damage or assembly and disassembly loss. This device maintains the cleanliness of the filter screen through non-destructive reverse blowing technology, prolongs its service life, and ensures the continuous and stable operation of the air flow transmission and deodorization system. 3. Improve the efficiency of the overall deodorization system: The cleanliness of the filter screen directly affects the intake concentration and load level of the downstream deodorization link. Through periodic reverse blowing, the initial gas filtration ability is maintained, the odor burden on the wet curtain and spray system is effectively reduced, and the overall deodorization effect and response speed of the system are improved. 4. The cleaning process has a high degree of automation and can be remotely controlled: The fan can be controlled in cooperation with an electric flipping mechanism or a programmable logic controller (PLC) system to achieve various working modes such as timed reverse blowing and differential pressure-triggered reverse blowing, meeting the needs of an intelligent breeding environment.

[0026] A wind direction adjustment mechanism is provided in the box body to adjust the flow direction of the gas in the box body. When the fan blows air in the reverse direction to clean the filter screen in the reverse direction, the wind direction of the reverse air flow can be adjusted through the wind direction adjustment mechanism. The wind direction adjustment mechanism drives the air flow to clean the filter screen at multiple angles; when adjusting the angle rotation of the air guide plate in the wind direction adjustment mechanism, the movement of the moving rod in the moving groove can drive the transmission rod to move left and right, and then drive the rotating plate to rotate. When the rotating plate rotates, it drives the air guide plate to rotate, realizing the adjustment of the angle of the air guide plate, and then adjusting the wind direction angle blowing on the filter plate.

[0027] And different numbers of wind guide plates can be opened as needed to increase the size of the wind force on the filter net locally, that is, the fewer the number of opened wind guide plates, the greater the wind force passing through the opened wind guide plates, and the stronger the cleaning force on the filter net; the filter net can be cleaned effectively by opening the wind guide plates at different positions in sequence. The position of the moving rod can be fixed when adjusting the position of the moving rod, and there is no technical restriction on the method of fixing the position of the moving rod. It is a prior art that can achieve the above functions (for example, increase the friction between the moving rod and the moving groove when it moves, etc., to ensure that the wind force does not cause the rotation of the wind guide plate, or set a limiting structure on the moving rod to limit the moving rod when it moves to a certain position. For example, a rotatable nut is set on the moving rod, and the nut and the moving rod are threadedly connected. By rotating the nut, the extrusion force between the fixed plates is adjusted to achieve the limitation of the moving rod. The specific structure is not limited).

[0028] The present application is also provided with a heat exchange mechanism, which can absorb the heat of the gas that needs to be discharged from the pig house and then recover the heat for reverse heating of the pig house or increasing the temperature of the gas entering the pig house, and can also heat the water source supplied to the pig house, etc.; in the heat exchange mechanism, the heat in the gas passing through the filter is absorbed by the collector (the collector can be a liquid injected into the pipeline, such as water or coolant, etc.) The collector recovers the heat in the gas, and an air duct is formed between the upper and lower pipelines for the gas to pass through. The temperature of the liquid in the collector increases after absorbing heat. If the height position of the radiator is higher than the collector, the liquid enters the radiator above through pipeline one, and the liquid with a lower temperature in the collector flows to the collector through pipelines two and three, realizing heat transfer and recovery, and dissipating the heat through the radiator, that is, the gas entering the pig house at the air inlet of the pig house can take away the heat through the radiator, thereby increasing the temperature of the gas entering the pig house; or the radiator is placed in the water supply tank of the pig house to heat the water in the water supply tank, etc.

[0029] In winter, the gas that needs to be deodorized can be used to recover heat through a heat exchange mechanism, that is, by rotating the air guide plate on the left side of the collector and closing the air guide plates at the ventilation gaps between adjacent collectors to ensure that most of the gas can pass through the collector, thereby realizing heat recovery in the gas.

[0030] When there is no need to recover heat from the gas, the air guide plate on the left side of the collector can be closed to prevent the gas from passing through the collector, and the air guide plates at the ventilation gaps between adjacent collectors can be opened to allow the gas to enter the right side of the box through the ventilation gaps to ensure smooth passage of airflow; if the heat dissipation temperature of the radiator does not affect the production of the pig house, all the air guide plates can be opened to allow smooth passage of airflow.

[0031] Beneficial effects:

[0032] A pigsty end deodorization device based on nano-mineral crystal agents provided by the present invention combines multi-stage purification methods of filtration adsorption and liquid deodorization, and has the following remarkable technical effects:

The nano-mineral crystal agents are combined with multi-stage wet curtains and spraying structures. Utilizing their high specific surface area and porous structure, it effectively enhances the adsorption and catalytic decomposition reactions of odor molecules, and greatly improves the deodorization efficiency.

[0034] 2. Self-cleaning fan structure: A reversible fan is set, combined with a wind direction adjustable mechanism and a one-way opening and closing valve, which can achieve reverse blowing cleaning without disassembling the filter screen. Through periodic reverse blowing, this structure effectively peels off impurities such as dust and hair attached to the surface of the filter screen, extends the service life of the filter screen, reduces the maintenance frequency, and improves the stability of the system operation.

[0035] 3. Intelligent air guiding and cleaning control: The wind direction adjustment mechanism is composed of linkage air guiding plates, which has the ability to adjust angles and control multi-stage wind directions, and realizes multi-angle and high-intensity cleaning air duct management of the filtration area. Its structure is simple and the response is fast, and it can be combined with the PLC automatic control system to achieve intelligent cleaning.

[0036] 4. Energy recovery and environmental protection and energy saving: A heat exchange mechanism is set, and the heat in the waste gas of the pigsty is recovered and reused by the heat exchange system of the collector and radiator. The heat energy can be used for pigsty heating, air preheating or water supply heating, improving the energy utilization rate, reducing the operation cost, and meeting the requirements of green and energy-saving breeding.

[0037] 5. Environment improvement and animal health promotion: The device can release water vapor during the deodorization process to adjust the humidity in the shed, effectively inhibit dust and bacteria growth. At the same time, the nano-mineral crystal has natural antibacterial properties, which helps to reduce the stimulation of harmful gases to the respiratory system of pigs and create a cleaner and healthier breeding environment.

[0038] 6. Modular design, convenient maintenance: The whole machine adopts a modular integrated design, with clear layout of each component, easy to disassemble, install and maintain; the deodorant liquid can achieve automatic liquid supplement and concentration monitoring to ensure stable supply of the agent, and the overall operation is efficient and reliable.

[0039] In summary, the present invention not only has high-efficiency, durable and intelligent deodorization capabilities, but also integrates multiple advanced functions such as self-cleaning, energy recovery and environmental regulation. It is a solution with high practicality and innovation in the field of current pigsty waste gas treatment. Brief Description of the Drawings

[0063] When this application is in use, when it is necessary to deodorize the gas discharged from the pigsty, the gas discharged from the pigsty enters the box body 1 through the air inlet on the left side of the box body 1 (by controlling the rotation of the fan 18 to drive the gas to be inhaled into the box body 1). When the gas enters the box body 1 through the air inlet plate 16 at the air inlet, (the air inlet plate 16 and the exhaust air plate 2 are breathable grille structures with a certain ventilation structure, which can block large suspended solids in the gas, etc.) the air inlet plate 16 blocks the large suspended solids in the gas to the outside of the box body 1. After the gas enters the box body 1, it passes through the filter screen 23. The filter screen 23 is a structure that can filter fine floating dust in the gas, which is an existing technology and will not be described in technical details. It can filter impurities and dust in the gas. The filter screen 23 filters the dust and impurities again; the gas then enters the middle of the box body 1 through the fan 18. The gas passes through the adsorption filter screen 20 under the blowing of the fan 18. (The adsorption filter screen 20 can filter and fix harmful gases. It adopts a multi-layer structure design. The first layer is a coconut shell activated carbon adsorption layer with a high specific surface area, which mainly adsorbs small and medium-sized organic / inorganic odor gases such as VOCs and H2S. The second layer is a modified zeolite molecular sieve layer with extremely strong ammonia selective adsorption ability, suitable for high-concentration ammonia in farms. The third layer oxidizes and decomposes some sulfides to improve the treatment efficiency of H2S. Through the above structure, deep adsorption of ammonia (NH3), hydrogen sulfide (H2S), volatile organic compounds (VOCs), etc. contained in the preliminarily filtered gas is achieved.) The porous adsorption material of the adsorption filter screen 20 fixes harmful gases through physical adsorption, chemical reactions, etc., extends the purification path and improves the treatment efficiency. The gas is then deodorized by the liquid deodorization mechanism. The liquid deodorization mechanism for pigsty gas includes four-level liquid deodorization units: wet curtain 1, spray pipe 1, spray pipe 2, and wet curtain 2. And a nano mineral crystal agent is uniformly used as the deodorant supply source to form a multi-stage, continuous, and efficient gas-liquid contact deodorization system, which has the following technical effects and advantages:

[0064] Segmented multi - stage deodorization, purifying odor gas layer by layer: The gas adsorbed by the solid filter screen first passes through the wet curtain - 5, and is initially pretreated through a large - area high - humidity environment to preliminarily dissolve water - soluble gases such as residual ammonia (NH3) and hydrogen sulfide (H2S) in the gas; then it is sprayed with nano - mineral crystal agents at high frequency through the spray pipe - 21 and the spray pipe - 22 to strengthen the contact reaction between the liquid medicine and the odor molecules; finally, the gas is settled through the wet curtain - 6 to further absorb the trace odor residues in the gas, achieving comprehensive and multiple purification of the odor. (Nano - mineral crystals have a high specific surface area and a porous lattice structure, which can quickly adsorb and catalytically decompose various odor molecules; after adding it to the deodorant liquid, it can not only actively participate in the neutralization reaction of the odor as an effective component in the liquid, but also form an adsorption layer on the surface of the wet curtain, extending the gas - liquid reaction path and improving the deodorization efficiency. Traditional deodorant liquids have limited effects on non - water - soluble VOCs, etc. The nano - mineral crystal agent is rich in metal oxides and silica - alumina skeletons, with good dual capabilities of catalytic oxidation and physical adsorption, and can treat various composite gases such as ammonia, methanethiol, and benzene series.) During the deodorization process, the system releases an appropriate amount of water vapor to adjust the air humidity in the pigsty, effectively reducing the dust and bacteria concentration; in addition, the nano - mineral crystal agent also has a certain antibacterial effect, which can further reduce the irritation of ammonia to the respiratory tract of pigs, improve the breeding environment, and enhance the health level of livestock and poultry. The four - stage deodorization structure is supplied with liquid by a unified liquid medicine supply system. The liquid medicine tank can be equipped with an automatic liquid supplement and concentration control device to ensure the stable operation of the spray and wet curtain systems, controllable deodorization effect, low maintenance cost, and convenient management.

[0065] The gas passing through the liquid deodorization mechanism is discharged outside the box body 1 through the air outlet, and the gas can be directly discharged to the outside of the pigsty, or the device can be directly used in the pigsty to realize the purification and circulation of the gas in the pigsty. When purifying the gas, due to the adoption of spray deodorization, there is a certain amount of moisture in the discharged gas, which can release an appropriate amount of water vapor to adjust the air humidity in the pigsty, effectively reducing the dust and bacteria concentration; in addition, the nano - mineral crystal agent also has a certain antibacterial effect, which can further reduce the irritation of ammonia to the respiratory tract of pigs, improve the breeding environment, and enhance the health level of livestock and poultry.

[0066] Since the gas environment in the pigsty is relatively dirty, the filter screen 23 needs to be frequently cleaned or replaced when filtering and purifying the gas. In this application, a reversible fan 18 is designed to blow air in the reverse direction. The fan 18 has the ability to adjust the air flow in both forward and reverse directions. Combined with the gas filter screen 23 provided at the front end, it can achieve effective ventilation and odor gas transportation under normal operating conditions, and realize the function of cleaning the filter screen 23 with reverse air flow during the maintenance stage, thus bringing the following beneficial technical effects: 1. Realize the function of self-cleaning the filter screen 23 without disassembly: By changing the working mode of the fan 18 from normal air supply to reverse blowing, the dust, hair, feed debris and other impurities accumulated on the outer surface of the filter screen 23 for a long time can be effectively stripped in the form of air flow, avoiding the influence of ventilation efficiency caused by pollutant blockage, reducing the maintenance frequency, and lowering the labor cost. 2. Prolong the service life of the filter screen 23 and improve the operation stability: The traditional filter screen 23 needs to be manually disassembled and cleaned regularly, which is easy to cause physical damage or assembly and disassembly loss. This device maintains the cleanliness of the filter screen through non-destructive reverse blowing technology, prolongs its service life, and ensures the continuous and stable operation of the air flow transportation and deodorization system. 3. Improve the efficiency of the overall deodorization system: The cleanliness of the filter screen directly affects the intake concentration and load level of the downstream deodorization link. Through periodic reverse blowing, the initial gas filtration ability is maintained, the odor burden on the wet curtain and spraying system is effectively reduced, and the overall deodorization effect and response speed of the system are improved. 4. The cleaning process has a high degree of automation and can be remotely controlled: The fan 18 can be controlled in cooperation with an electric flipping mechanism or a programmable logic controller (PLC) system to achieve various working modes such as timed reverse blowing and differential pressure-triggered reverse blowing, meeting the requirements of an intelligent breeding environment.

[0067] A wind direction adjustment mechanism is provided in the box body 1 to adjust the flow direction of the gas in the box body 1. When the fan 18 blows air in the reverse direction to clean the filter screen 23 in the reverse direction, the wind direction of the reverse air flow can be adjusted through the wind direction adjustment mechanism. The wind direction adjustment mechanism drives the air flow to clean the filter screen 23 from multiple angles; when adjusting the angle rotation of the air deflector 24 in the wind direction adjustment mechanism, the movement of the moving rod 29 in the moving groove can drive the transmission rod 32 to move left and right, and then drive the rotating plate 31 to rotate. When the rotating plate 31 rotates, it drives the air deflector 24 to rotate, realizing the adjustment of the angle of the air deflector 24, and then adjusting the wind direction angle blowing towards the filter plate 27.

[0068] Moreover, different numbers of air guide plates 24 can be opened as needed, which can increase the wind force on the filter screen 23 locally. That is, the fewer the number of opened air guide plates 24, the greater the wind force passing through the opened air guide plates 24 and the stronger the cleaning strength on the filter screen 23. The strong cleaning of the filter screen 23 can be achieved by sequentially opening the air guide plates 24 at different positions. When adjusting the position of the moving rod 29, the position of the moving rod 29 can be fixed. The fixing method of the position of the moving rod 29 is not limited technically and is an existing technology as long as the above functions can be achieved (for example, increasing the friction between the moving rod 29 and the moving slot during movement to ensure that the wind force will not cause the rotation of the air guide plate 24, or setting a limiting structure on the moving rod 29 to limit the moving rod 29 when it moves to a certain position. For example, a rotatable nut is provided on the moving rod 29, and the nut is threadedly connected to the moving rod 29. By rotating the nut, the extrusion force between the fixing plates 7 is adjusted to realize the limitation of the moving rod 29. The specific structure is not limited,).

[0069] The present application is also provided with a heat exchange mechanism, which can absorb the heat of the gas to be discharged in the pigsty and then recycle the heat for reverse heating of the pigsty or increase the temperature of the gas entering the pigsty, or can also heat the water source supplied to the pigsty, etc. In the heat exchange mechanism, the heat of the gas passing through the filter screen 23 is absorbed by the collector 25 (the collector 25 can be filled with a liquid in the pipeline, such as water or coolant, etc.). The collector 25 recovers the heat of the gas, and a wind channel is formed between the upper and lower pipelines for the gas to pass through. After the liquid in the collector 25 absorbs the heat, its temperature rises. If the height position of the radiator 4 is higher than that of the collector 25, the liquid enters the upper radiator 4 through the pipeline 15. Then, the liquid with a lower temperature in the collector flows to the collector 25 through the pipeline 14 and the pipeline 11 to realize the transfer and recovery of heat. The heat is dissipated through the radiator 4. That is, the gas entering the pigsty at the air inlet of the pigsty can take away the heat through the radiator 4, increasing the temperature of the gas entering the pigsty. Or the radiator 4 is placed in the water supply tank of the pigsty to heat the water in the water supply tank, etc.

[0070] In winter, the gas to be deodorized can pass through the heat exchange mechanism for heat recovery, that is, by rotating the air guide plate 24 on the left side of the collector 25 and closing the air guide plates 24 at the ventilation gaps provided between adjacent collectors 25, ensuring that most of the gas can pass through the collector 25, and thus the heat recovery of the gas can be realized.

[0071] When heat recovery from the gas is not required, the air deflector 24 on the left side of the collector 25 can be closed to prevent the gas from passing through the collector 25. The air deflector 24 at the ventilation gap between adjacent collectors 25 is opened, allowing the gas to enter the right side of the box body 1 through the ventilation gap to ensure the smooth flow of the air current. If the heat dissipation temperature of the radiator 4 does not affect the production in the pigsty, all the air deflectors 24 can also be opened to allow the air current to pass through smoothly.
