Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, and in particular relates to an environmental control system for enclosed high-rise pig houses. Background Technology

[0002] Currently, ventilation systems in multi-story pig farms generally adopt a stacked arrangement of ventilation systems from single-story pig farms, meaning each floor has its own independent ventilation system. However, as the number of floors in a multi-story pig farm increases, the external environmental parameters become more variable, requiring independent control of the ventilation system on each floor. This leads to operational and management difficulties, and the dispersed placement of ventilation equipment results in high hardware and maintenance costs, hindering standardized management. For example, document CN113455411A, "A Ventilation System for Multi-story Pig Farms," ​​discloses a ventilation system that can supply and exhaust air to each floor of the pig farm, but it cannot promptly remove odors from the pig farm, offering limited improvement to the overall air quality. Document CN213246218U, "A Thermal Insulation and Ventilation System for Multi-story Pig Farms," ​​also discloses a system, but the airflow between adjacent floors is interconnected, compromising the independence of each floor and hindering biosecurity control. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a closed high-rise pig house environmental control system with a simple structure, which can realize centralized air supply and exhaust of the entire building body, while ensuring good air environment of each breeding floor, and is relatively closed and independent.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A closed high-rise pigsty environmental control system includes a closed building body, the bottom floor of which is a raised floor, and the remaining floors of the building body are breeding floors. A manure discharge trough is recessed in the floor slab of each breeding floor. The system also includes a fresh air treatment device, an air supply duct, a static pressure box, an exhaust duct, and a waste gas treatment device. The fresh air treatment device is located within the raised floor, and the waste gas treatment device is located on the rooftop of the building body. Each breeding floor has a static pressure box with an air inlet. The fresh air treatment device has an air outlet, and the waste gas treatment device has an air inlet. The air outlet of the fresh air treatment device is connected to the air inlet of each static pressure box through the air supply duct. The floor slab of each breeding floor also includes... The system includes ventilation ducts arranged parallel to the sewage troughs, and air vents connecting the ventilation ducts to the corresponding sewage troughs within the floor slab. Multiple ventilation ducts are connected to the air inlet of the waste gas treatment device via the exhaust duct. The fresh air treatment device purifies and regulates the temperature of fresh air before supplying it to the air supply duct. The waste gas treatment device draws in waste gas from the exhaust duct, purifies it, and discharges it externally. Each static pressure air box has two air inlet interfaces. The air supply duct has multiple air inlet branch pipes, with each air inlet interface corresponding to one air inlet branch pipe. Each air inlet branch pipe has a switching valve. The two air inlet branch pipes corresponding to each static pressure air box are a first air inlet branch pipe and a second air inlet branch pipe, with the second air inlet branch pipe bypassing the ventilation duct.

[0005] The beneficial effects of the above technical solution are as follows: The fresh air handling device delivers air to the static pressure box in each breeding layer via the air supply duct. The static pressure box ensures more uniform fresh air supply throughout each breeding layer. Furthermore, by installing ventilation ducts connected to the manure discharge trough through air holes within the floor slab, and connecting the exhaust gas treatment device to each ventilation duct via the exhaust duct, exhaust gas from the breeding layer is discharged through the manure discharge trough. This creates a negative pressure environment within the manure discharge trough, preventing odors from diffusing into the breeding layer and thus improving the overall air quality of the breeding layer. Additionally, the relatively enclosed and independent design of each breeding layer is beneficial for improving the overall air quality of the breeding area. Biosecurity measures are implemented; additionally, the entire building shares a common fresh air treatment unit and exhaust gas treatment unit, which helps reduce costs and facilitates control, ensuring a relatively consistent control environment across all breeding floors; and two air inlets are installed, allowing the switching valve on the second air inlet branch to be closed and the switching valve on the first air inlet branch to be opened in summer, while in winter, the switching valve on the second air inlet branch to be opened and the switching valve on the first air inlet branch to be closed. This fully utilizes the heat in the exhaust gas to preheat the fresh air passing through the second air inlet branch, thereby reducing heat loss in the pig breeding floors during winter and reducing the overall energy consumption of the entire building.

[0006] In the above technical solution, each of the ventilation ducts and the corresponding manure troughs has multiple air holes spaced apart along their length.

[0007] The beneficial effects of the above technical solution are: it enables the exhaust gas treatment device to perform multi-point suction in the manure discharge trough, so as to ensure smoother airflow discharge throughout the breeding layer, thereby making the air quality more uniform throughout the breeding layer.

[0008] The static pressure air box described in the above technical solution includes a straight box and multiple air supply boxes. A dividing plate is provided inside the box along its length, dividing the box into two chambers, namely a first chamber and a second chamber. The dividing plate is provided with multiple ventilation holes that connect the first chamber and the second chamber. The air inlet is provided on the box and communicates with the first chamber. Multiple air supply boxes are installed on the box and are spaced apart along the length of the box. Each air supply box has an air supply hole that communicates with the second chamber at its connection with the box. Multiple exhaust nozzles that communicate with the interior of the exhaust box are protruding from the side of the outer wall of the air supply box away from the air supply hole.

[0009] The beneficial effect of the above technical solution is that it enables the fresh air entering the static pressure air box to be evenly discharged throughout the breeding layer through multiple air supply boxes, thus avoiding the problem of insufficient fresh air supply in some areas.

[0010] In the above technical solution, multiple ventilation holes are spaced apart along the length of the dividing plate; the static pressure air box also includes multiple baffles, which are spaced apart along the length of the box in the second chamber, and each baffle corresponds to a ventilation hole, with each baffle aligned with the corresponding ventilation hole.

[0011] The beneficial effect of the above technical solution is that most of the fresh air supplied to the second chamber through each ventilation hole is directly introduced into the air supply box through the air supply hole under the action of the baffle plate, which can ensure that the air pressure and air volume in the air supply box remain relatively stable.

[0012] In the above technical solution, the box is horizontally arranged and has a square cross-section. The dividing plate is vertically inclined inside the box. The first chamber is located above the dividing plate, and the second chamber is located below the dividing plate. The air inlet is located at the upper end of the box, and the air supply box is located at the lower end of the box. The baffle is vertically inclined inside the second chamber, and the upper end of the baffle is connected to the dividing plate. The lower end of the baffle is connected to the inner bottom wall of the box, and the air supply hole and the ventilation hole are located on the same side of the baffle.

[0013] The beneficial effects of the above technical solution are: its structure is simple, and it makes a certain angle between the vent and the corresponding air supply hole, and the baffle plate plays the role of guiding the airflow between the two.

[0014] The static pressure air box described in the above technical solution also includes an air inlet chamber protruding from the upper end of the box and communicating with the first box chamber. The air inlet interface is connected to the air inlet chamber. The inner center of the first box chamber is provided with a plurality of baffles arranged in the front-back direction and spaced apart in the left-right direction. The baffles are provided with a plurality of ventilation holes that communicate in the left and right directions.

[0015] The beneficial effect of the above technical solution is that the fresh air entering the first chamber can be distributed more evenly under the action of the air intake chamber and the baffle, so that the static pressure in the first chamber is relatively consistent, which is conducive to making the air intake volume in the second chamber relatively balanced.

[0016] The fresh air handling device described in the above technical solution includes a first filter, a wet curtain box, a heating box, and a fresh air fan connected sequentially along the fresh air delivery direction, and the air outlet of the fresh air fan constitutes the air outlet of the fresh air handling device.

[0017] The beneficial effects of the above technical solution are as follows: the first filter can filter the fresh air entering the fresh air treatment device, and the fresh air in the wet curtain box is cooled in summer, while the fresh air is heated in the heating box in winter, thereby achieving the control of the room temperature of the breeding layer, and the fresh air fan provides power for the delivery of fresh air.

[0018] The exhaust gas treatment device described in the above technical solution includes a spray box, a nozzle, an exhaust gas fan, a second filter, and a water pump. The spray box has an air inlet and an air outlet. The air outlet of the exhaust gas fan is connected to the air inlet of the spray box. The nozzle is installed inside the spray box. The second filter is installed at the air outlet of the spray box. The water pump is installed in the spray box and is connected to the nozzle.

[0019] The beneficial effects of the above technical solution are as follows: the exhaust gas is powered by the exhaust gas fan, and is first deodorized in the spray box, and then filtered by the second filter. The water pump is used to supply the deodorizing liquid in the spray box to the spray head to realize the recycling of the deodorizing liquid.

[0020] The air supply duct and exhaust duct described in the above technical solution both have ventilation shafts integrally formed with the building body.

[0021] The beneficial effect of the above technical solution is that the main passages of the air supply and exhaust channels can be directly replaced by ventilation shafts.

[0022] In the above technical solution, a trench fan is also provided at the connection between each of the ventilation ducts and the exhaust ducts.

[0023] The beneficial effect of the above technical solution is that it makes the ventilation duct more effective at drawing out the odor from the manure trough. Attached Figure Description

Detailed Implementation

[0039] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0040] Example 1

[0041] like Figures 1-3As shown, this embodiment provides a closed high-rise pigsty environmental control system, including a closed building body 1. The ground floor of the building body 1 is a raised floor 11, and the remaining floors of the building body 1 are breeding floors 12. The floor slab of the breeding floor 12 is recessed with a manure discharge trough 121. It also includes a fresh air treatment device 2, an air supply duct 3, a static pressure box 4, an exhaust duct 5, and a waste gas treatment device 6. The fresh air treatment device 2 is installed in the raised floor 11, and the waste gas treatment device 6 is installed on the roof of the building body 1. Each of the breeding floors... Each of the 12 indoor units is equipped with a static pressure air box 4, which has an air inlet 411. The fresh air treatment device 2 has an air outlet, and the exhaust gas treatment device 6 has an air inlet. The air outlet of the fresh air treatment device 2 is connected to the air inlet 411 of each static pressure air box 4 through the air supply channel 3. The floor slab of the breeding layer 12 is also equipped with a ventilation duct 122 arranged parallel to the manure discharge trough 121, and the floor slab is also equipped with air holes 123 that connect the ventilation duct 122 to the corresponding manure discharge trough 121. The ventilation ducts 122 are all connected to the air inlet of the exhaust gas treatment device 6 through the exhaust duct 5. The fresh air treatment device 2 is used to purify and regulate the temperature of the fresh air and supply it to the air supply duct 3. The exhaust gas treatment device 6 is used to draw in the exhaust gas in the exhaust duct 5, purify the exhaust gas, and discharge it. In this way, the fresh air treatment device supplies air to the static pressure box in each breeding layer through the air supply duct. By setting the static pressure box, the fresh air supplied to each breeding layer can be more uniform. And by setting air holes in the floor slab to communicate with the manure discharge trough, the fresh air can be distributed more evenly. The ventilation ducts are connected to the exhaust ducts, and the exhaust gas treatment device is connected to each ventilation duct. This allows the exhaust gas in the breeding layer to be discharged through the manure discharge trough, which creates a negative pressure in the manure discharge trough. This prevents the odor in the manure discharge trough from spreading into the indoor breeding layer, thereby improving the air quality of the entire breeding layer. It also makes each breeding layer relatively closed and independent, which is conducive to improving the biosecurity and disease control of the breeding area. In addition, the entire building shares the fresh air treatment device and the exhaust gas treatment device, which helps to reduce costs and facilitates control, ensuring that the control environment of each breeding layer is relatively consistent.

[0042] like Figure 3 and Figure 4 As shown, in the above technical solution, each of the ventilation ducts 122 and the corresponding manure discharge trough 121 has multiple air holes 123 spaced apart along their length direction. This allows the exhaust gas treatment device to perform multi-point suction in the manure discharge trough, ensuring smoother airflow discharge throughout the entire breeding layer, thereby making the air quality more uniform throughout the breeding layer.

[0043] like Figure 3 and Figure 4As shown, in this embodiment, the upper end of the manure discharge trough can be covered with a manure slat 1211 (the material of which can be a strong load-bearing and grid-shaped concrete component). The main function of the manure slat 1211 is to bear the weight in the pig's activity area and to allow the manure to leak from the holes into the manure discharge trough. Its structure is similar to the grid cover on the roadside rainwater ditch. In this embodiment, the ventilation duct 122 can be a ventilation ditch 1221 set on the floor slab parallel to the manure discharge trough, and then a cover plate 1222 is placed on the upper end of the ventilation ditch 1221 to form a enclosure. The cover plate can be a steel plate or a precast concrete slab.

[0044] like Figures 5-9 As shown, the static pressure air box 4 in the above technical solution includes a straight box 41 and multiple air supply boxes 42. A dividing plate 412 is provided inside the box 41 along its length, dividing the box 41 into two chambers 413, namely a first chamber 413a and a second chamber 413b. The dividing plate 412 is provided with multiple ventilation holes 4121 communicating with the first chamber 413a and the second chamber 413b. The air inlet 411 is located on the box 41 and connects to the first chamber 413a. 3a is connected, and multiple air supply boxes 42 are installed on the box 41 and are spaced apart along the length of the box 41. Each air supply box 42 is provided with an air supply hole 421 communicating with the second chamber 413b at the connection between it and the box 41. Multiple exhaust nozzles 422 communicating with the interior are protruding on the outer wall of the air supply box 42 away from the air supply hole 421. In this way, the fresh air entering the static pressure air box can be evenly discharged in all parts of the breeding layer through multiple air supply boxes, avoiding the problem of insufficient fresh air supply in some areas.

[0045] like Figure 6 and Figure 7 As shown, in the above technical solution, multiple ventilation holes 4121 are spaced apart along the length of the dividing plate 412, thus making the air intake of each air supply box relatively uniform. The static pressure air box 4 also includes multiple baffles 414, which are spaced apart along the length of the box 41 in the second chamber 413b. Each baffle corresponds to a ventilation hole 4121, and the air supply hole and ventilation hole are located on the same side of the baffle. This ensures that the fresh air supplied to the second chamber through each ventilation hole is evenly distributed in the second chamber under the buffering effect of the baffle, and then enters the air supply box through the air supply hole, thereby ensuring that the air pressure in each air supply box is relatively consistent.

[0046] The upper end of the baffle is connected to the dividing plate, and the lower end of the baffle is connected to the bottom wall of the second chamber or the upper end of the air supply box.

[0047] like Figure 6 and Figure 7 As shown, in the above technical solution, the box 41 is horizontally arranged and has a square cross-section. The dividing plate 412 is vertically inclined and arranged inside the box 41. The first chamber 413a is located above the dividing plate 412, and the second chamber 413b is located below the dividing plate 412 (taking the dividing plate as vertically inclined as an example, the side inclined upwards corresponds to the first chamber, and vice versa). The air inlet 411 is located at the upper end of the box 41, and the air supply box 42... The baffle plate 414 is vertically inclined and installed at the lower end of the box 41. The upper end of the baffle plate 414 is connected to the dividing plate 412, and the lower end of the baffle plate 414 is connected to the inner bottom wall of the box 41. The corresponding air supply hole 421 and air vent 4121 are located on the same side of the corresponding baffle plate 414. The structure is simple and makes the air vent and the corresponding air supply hole have a certain angle. The baffle plate plays the role of guiding the airflow between the two.

[0048] like Figures 5-7 and Figure 9 As shown, preferably, an air intake cavity 415 protrudes from the middle of the upper end of the box 41, communicating with the first chamber 413a, and the air inlet 411 is located at the upper end of the air intake cavity 415 (the air inlet communicates with the air intake cavity); more preferably, multiple baffles 416 can be vertically arranged at the middle position of the first chamber 413a, the baffles 416 are arranged along the width direction of the box in the first chamber 413a, and the multiple baffles 416 are spaced apart along the length direction of the box 41 in the first chamber 413a, and multiple ventilation holes 4161 are spaced apart along their length direction on the baffles 416. In this embodiment, there is a gap between the upper end of the baffle 416 and the top wall of the box 41 to allow airflow to pass through.

[0049] like Figure 1 , Figure 2 and Figure 12 As shown, in the above technical solution, each of the ventilation ducts 122 and the exhaust duct 5 is also provided with a trench fan 7, which makes the ventilation duct more effective at sucking up the odor in the manure trough.

[0050] like Figure 10As shown, the fresh air treatment device 2 in the above technical solution includes a first filter 21, a wet curtain box 22, a heating box 23, and a fresh air fan 24 connected sequentially along the fresh air delivery direction. The air outlet of the fresh air fan 24 constitutes the air outlet of the fresh air treatment device 2. This allows the first filter to filter the fresh air entering the fresh air treatment device, while in summer the fresh air in the wet curtain box is cooled, and in winter the heating box heats the fresh air, thereby achieving temperature control of the breeding layer. The fresh air fan provides power for the delivery of fresh air.

[0051] In this embodiment, the filter element in the first filter can be divided into multiple layers. Along the fresh air delivery direction, it can consist of a filter screen (approximately 100-200 mesh), a calcium chloride filling layer, and an activated carbon filling layer. Calcium chloride has good adsorption and bactericidal properties, thus preventing harmful bacteria from entering the breeding layer. The evaporative cooling box in this embodiment is existing technology. An air-source heat pump can be installed inside the heating box as a heating element. In summer, the evaporative cooling box and the fresh air fan combine to form a cooling system (the heating box does not operate). In winter, the heating box and the fresh air fan combine to form a hot air supply system (the evaporative cooling box does not operate).

[0052] like Figure 11 As shown, the exhaust gas treatment device 6 in the above technical solution includes a spray box 61, a nozzle 62, an exhaust gas fan 63, a second filter 64, and a water pump 65. The spray box 61 has an air inlet and an air outlet. The air outlet of the exhaust gas fan 63 is connected to the air inlet of the spray box 61. The nozzle 62 is installed inside the spray box 61. The second filter 64 is installed at the air outlet of the spray box 61. The water pump 65 is installed in the spray box 61 and connected to the nozzle 62. This allows the exhaust gas to be powered by the exhaust gas fan, undergo deodorization treatment in the spray box, and then be filtered by the second filter. The water pump supplies the deodorizing liquid in the spray box to the nozzle to achieve the recycling of the deodorizing liquid. Specifically, in this embodiment, the spray box is horizontally arranged, with an air inlet and an air outlet at its two ends. The air outlet and the lower end of the spray box, located below the nozzle, can be recessed to form a liquid collection tank 611. Multiple nozzles can be provided, all of which are spray nozzles, allowing the mist sprayed from multiple nozzles to form a mist wall within the spray box. The liquid collection tank can be located immediately below and behind the mist wall. The liquid sprayed from the nozzles can be a deodorizing liquid (a disinfectant can also be added to the deodorizing liquid as needed). The water pump can be a submersible pump, located within the liquid collection tank, with its outlet connected to the nozzle. The second filter can be made of multiple layers of plastic filter screen or metal wire mesh (which can block liquid mist penetration). The deodorizing liquid in the liquid collection tank can be replaced periodically (a liquid inlet and a liquid outlet can be provided at the liquid collection tank, and valves can be installed at both the liquid inlet and the liquid outlet; this is existing technology and will not be elaborated here).

[0053] In the above technical solution, both the air supply duct 3 and the exhaust duct 5 have an air shaft 13 integrally formed with the building body 1, so that the main passage of the air supply duct and the exhaust duct can be directly replaced by an air shaft.

[0054] like Figure 1 As shown, in this embodiment, each breeding floor of the building body can be divided into a breeding area 20 and a corridor area 10 (the corridor area and breeding area are not distinguished in the open floor). The corridor area can be equipped with stairs or elevators, and the breeding area and the corridor area are closed except for the addition of an entrance and exit door. Each breeding floor can be equipped with only one breeding area.

[0055] For the air supply duct, its corresponding air shaft 13 is the main air supply duct. The static pressure air box of each breeding layer is connected to the corresponding air shaft through pipes. For the exhaust duct, its corresponding air shaft is the main exhaust duct. The air inlet of the exhaust gas treatment device is connected to the upper end of the corresponding air shaft. Each trench fan can be directly embedded at the connection between the ventilation duct and the corresponding air shaft. The air shaft corresponding to the exhaust duct can be located in the building body near the corridor area, while the air supply duct can be located on the side of the building body away from the corridor area. The branch passages of the exhaust duct and the air supply duct can be made of PVC pipes.

[0056] like Figure 3 , Figure 7 , Figure 9 and Figure 12 As shown, in this embodiment, the static pressure air box 4 can have two air inlet ports 411. Each static pressure air box 4 is connected to the corresponding air shaft 13 via two air inlet branch pipes 31. One of the air inlet branch pipes 31 can be installed within the corresponding ventilation duct 122. Both air inlet branch pipes 31 are equipped with switching valves 32. The two air inlet branch pipes can be a first air inlet branch pipe 31a and a second air inlet branch pipe 31b, respectively. The second air inlet branch pipe 31b passes through the ventilation duct, thus allowing for ventilation in summer. Close the switching valve on the second air intake branch pipe 31b and open the switching valve on the first air intake branch pipe. In winter, the switching valve on the second air intake branch pipe 31b can be opened and the switching valve on the first air intake branch pipe can be closed. This can make full use of the heat in the exhaust gas to preheat the fresh air passing through the second air intake branch pipe, thereby reducing the heat loss in the pig farming floor in winter and reducing the overall energy consumption of the building. (In spring and autumn, the static pressure box can be flexibly selected to use the first air intake branch pipe or the second air intake branch pipe for air intake according to the temperature conditions.)

[0057] In this embodiment, the static pressure air box is suspended on the ceiling of the corresponding breeding area, while the manure discharge trough and ventilation ditch are installed on the floor slab of the corresponding breeding area. The number of static pressure air boxes, manure discharge troughs and ventilation ditches in each breeding area is determined according to needs.

[0058] Example 2

[0059] like Figure 13 and Figure 14 As shown in Example 1, the difference is that each breeding layer can also be set with two breeding areas 20, and the corridor area 10 is located between the two breeding areas 20. At this time, two fresh air handling devices, air supply channels and exhaust channels can be set, while one exhaust gas treatment device can be shared. At this time, the breeding areas on the same side are regarded as a breeding unit and are independently matched with a set of fresh air handling devices, air supply channels and exhaust channels, but both exhaust channels are connected to the exhaust gas treatment device (of course, when the air supply of the fresh air handling device is sufficient, the two breeding units can also share one fresh air handling device).
