Description

Technical Field

[0001] The present invention belongs to the technical field of aquaculture, and particularly relates to a ventilation system for a closed high-rise aquaculture building. Background Art

[0002] At present, the ventilation systems of multi-story pig houses generally adopt the method of superimposing the ventilation systems of single-story pig houses, that is, each floor of the pig house is independently equipped with a ventilation system. As the number of floors of the pig house increases, the changes in external environmental parameters increase, and the ventilation systems of each floor of the pig house need to be independently controlled. This will lead to difficulties in operation and management, and the ventilation equipment is scattered, resulting in high hardware costs and maintenance costs, which is not conducive to standardized management. For example, a ventilation system disclosed in the patent document with the document number CN113455411A "A Ventilation System for Building Aquaculture" can supply air and exhaust air to each floor of the pig house, but it cannot timely remove the odor in the pig house, and the improvement of the overall air environment in the pig house is limited; the patent document with the document number CN213246218U "A Thermal Insulation and Ventilation System for a Building-Type Pig Farm" also discloses a breeding system, but there is an air flow connection between the upper and lower adjacent floors of the pig house, which destroys the independence of each floor of the pig house and is not conducive to biosafety prevention and control. Summary of the Invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a closed high-rise aquaculture building ventilation system with a simple structure, which can realize centralized air supply and exhaust of the entire building body, ensure a good air environment in each aquaculture layer, and is relatively closed and independent.

[0004] To achieve the above object, the technical solution of the present invention is as follows: A closed high-rise aquaculture building ventilation system includes a closed building body. The bottom layer of the building body is an overhead layer, and the remaining floors of the building body are all aquaculture layers. A manure discharge groove is recessed on the floor slab of the aquaculture layer. The ventilation system further includes a fresh air treatment device, a air supply channel, a static pressure air box, an exhaust air channel and an exhaust gas treatment device. The fresh air treatment device is arranged in the overhead layer, and the exhaust gas treatment device is arranged on the roof of the building body. A static pressure air box is arranged in the room of each aquaculture layer. The static pressure air box has an air inlet interface. The fresh air treatment device has an air outlet, and the exhaust gas treatment device has an air inlet. The air outlet of the fresh air treatment device is communicated with the air inlet interface of each static pressure air box through the air supply channel. A ventilation duct parallel to the manure discharge groove is further arranged in the floor slab of the aquaculture layer, and air holes for communicating the ventilation duct with the corresponding manure discharge groove are further arranged in the floor slab. A plurality of ventilation ducts are all communicated with the air inlet of the exhaust gas treatment device through the exhaust air channel. The fresh air treatment device is used for purifying and adjusting the temperature of fresh air and supplying it into the air supply channel, and the exhaust gas treatment device is used for sucking the exhaust gas in the exhaust air channel, purifying the exhaust gas and discharging it outside.

[0005] The beneficial effect of the above technical solution is that the fresh air treatment device supplies air to the static pressure bellows in each breeding layer through the air supply channel. By setting the static pressure bellows, the fresh air supplied to each place in each breeding layer can be more uniform. By setting a ventilation duct connected to the manure trough through the air hole in the floor slab, and the exhaust gas treatment device is connected to each ventilation duct through the exhaust channel, the exhaust gas in the breeding layer is discharged through the manure trough, so that the manure trough is in a negative pressure state, and the odor in the manure trough is not easy to spread to the indoor of the breeding layer, which is beneficial to improving the air quality of the entire breeding layer, and making each breeding layer more closed and independent, which is beneficial to improving the biosafety prevention and control of the breeding area; in addition, the entire building body shares the fresh air treatment device and the exhaust gas treatment device, which is beneficial to reducing costs and facilitating control, and can ensure that the control environment of each breeding layer is relatively consistent.

[0006] In the above technical solution, each ventilation duct and the corresponding feces discharge trough are provided with a plurality of air holes spaced apart along the length direction of the two ducts.

[0007] The beneficial effect of the above technical solution is that the waste gas treatment device can perform multi-point suction in the manure trough to ensure smoother air discharge in the entire breeding layer, thereby making the air quality in various parts of the breeding layer more uniform.

[0008] The static pressure wind box in the above technical solution includes a straight box and a plurality of air supply boxes, a partition plate is arranged inside the box along its length direction, the partition plate divides the box into two chambers, the two chambers are respectively a first chamber and a second chamber, a plurality of air vents connecting the first chamber and the second chamber are arranged on the partition plate, the air inlet interface is arranged on the box and connected to the first chamber, a plurality of air supply boxes are installed on the box and are spaced apart on the box along the length direction of the box, an air supply hole connected to the second chamber is arranged at the connection between each of the air supply boxes and the box, and a plurality of exhaust nozzles connected to the interior of the air supply box are convexly provided on the side of the outer wall of the air supply box facing away from the air supply hole.

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

[0010] In the above technical solution, the plurality of air holes are spaced apart on the dividing plate along the length direction thereof; the static pressure wind box further comprises a plurality of baffles, and the plurality of baffles are spaced apart in the second box chamber along the length direction of the box box, and the plurality of baffles correspond one-to-one to the plurality of air holes, and each baffle is aligned with the corresponding air hole.

[0011] The beneficial effect of the above technical solution is that most of the fresh air sent into the second chamber through each air vent can directly enter the air supply box through the air supply hole under the action of the baffle, thus ensuring that the wind pressure and air intake volume in the air supply box remain relatively stable.

[0012] In the above technical solution, the box is horizontally arranged, and its cross-section is square, the dividing plate is vertically inclined arranged in the box, the first box chamber is located above the dividing plate, the second box chamber is located below the dividing plate, and the air inlet interface is arranged at the upper end of the box, the air supply box is arranged at the lower end of the box, the baffle is vertically inclined arranged in the second box 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 air 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 a certain angle is provided between the air vent and the corresponding air supply hole, and the baffle plays a role in guiding the airflow between the two.

[0014] The static pressure bellows described in the above technical solution also includes an air inlet cavity 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 cavity. A plurality of baffles are vertically provided in the inner middle part of the first box chamber, which are arranged along the front-to-back direction and spaced apart along the left-to-right direction. A plurality of ventilation holes are provided on the baffles, which communicate with 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 inlet cavity and the baffle, so that the static pressure at various locations in the first chamber is relatively consistent, which is conducive to making the air intake volume at various locations in the second chamber relatively balanced.

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

[0017] The beneficial effect of the above technical solution is that the first filter can filter the fresh air entering the fresh air treatment device, and in summer the fresh air is cooled by the wet curtain box, and in winter the fresh air is heated by the heating box, 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] In the above technical solution, the waste gas treatment device includes a spray box, a spray head, a waste gas fan, a second filter, and a water pump.

The second filter is arranged at the air outlet of the spray box. The water pump is arranged in the spray box and is communicated with the spray head.

[0019] The beneficial effect of the above technical solution is that: in this way, the waste gas is powered by the waste gas fan, and first undergoes deodorization treatment in the spray box, and then is 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] In the above technical solution, both the air supply channel and the exhaust air channel have air shafts integrally formed with the building body.

[0021] The beneficial effect of the above technical solution is that: in this way, the main passageways of the air supply channel and the exhaust air channel can be directly replaced by air shafts.

[0022] In the above technical solution, each static pressure air box is provided with two air inlet interfaces. The air supply channel has multiple air inlet branch pipes. Each air inlet interface corresponds to one air inlet branch pipe, and each air inlet branch pipe is provided with a switching valve. The two air inlet branch pipes corresponding to each static pressure air box are respectively a first air inlet branch pipe and a second air inlet branch pipe. The second air inlet branch pipe winds around and passes through the ventilation duct.

[0023] The beneficial effect of the above technical solution is that: in this way, the switching valve on the second air inlet branch pipe can be closed and the switching valve on the first air inlet branch pipe can be opened in summer, while in winter, the switching valve on the second air inlet branch pipe can be opened and the switching valve on the first air inlet branch pipe can be closed. In this way, the heat in the waste gas can be fully utilized to preheat the fresh air passing through the second air inlet branch pipe, thereby reducing the indoor heat loss in the pig-raising layer in winter and overall reducing the energy consumption of the entire building body.

The fresh air treatment device 2 is used to purify and adjust the temperature of the fresh air and supply it to the air supply channel 3. The exhaust gas treatment device 6 is used to suck the exhaust gas in the exhaust channel 5 and purify the exhaust gas and discharge it to the outside. In this way, the fresh air treatment device supplies air to the static pressure wind box in each breeding layer through the air supply channel. By setting the static pressure wind box, the fresh air sent to each breeding layer can be more uniform. By setting the air hole in the floor slab to communicate with the manure trough, The exhaust gas treatment device is connected with each ventilation duct through the exhaust channel, so that the exhaust gas in the breeding layer is discharged through the manure trough, which makes the manure trough present a negative pressure, and the odor in the manure trough is not easy to spread to the indoor of the breeding layer, which is beneficial to improving the air quality of the entire breeding layer, and makes each breeding layer more closed and independent, which is beneficial to improving the biosafety prevention and control of the breeding area; in addition, the whole building body shares the fresh air treatment device and the exhaust gas treatment device, which is beneficial to reduce costs and facilitate control, and can ensure 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, there are multiple air holes 123 spaced apart along the length direction between each ventilation duct 122 and the corresponding manure trough 121, so that the exhaust gas treatment device can perform multi-point suction in the manure trough to ensure that the airflow in the entire breeding layer is discharged more smoothly, thereby making the air quality in various places in the breeding layer more uniform.

[0043] like Figure 3 and Figure 4As shown, the upper end of the manure trough described in this embodiment can be covered with a manure-leaking board 1211 (the material of which can be a concrete part with strong load-bearing capacity and grid-shaped), and the main function of the manure-leaking board is to bear the weight in the pig's activity area and to leak the feces from the slits into the manure trough; the ventilation duct 122 described in this embodiment can be a ventilation groove 1221 arranged on the floor slab in parallel with the manure trough, and then the upper end of the ventilation groove 1221 is covered with a cover plate 1222 to enclose it, and the cover plate can be a prefabricated plate made of steel plate or concrete material.

[0044] like Figures 5 - 9 As shown, the static pressure wind box 4 in the above technical solution includes a straight box 41 and a plurality of air supply boxes 42, a partition plate 412 is arranged in the box 41 along its length direction, the partition plate 412 divides the box 41 into two chambers 413, the two chambers 413 are respectively a first chamber 413a and a second chamber 413b, a plurality of air holes 4121 are arranged on the partition plate 412, which connect the first chamber 413a and the second chamber 413b, the air inlet interface 411 is arranged on the box 41, and is connected to the first chamber 41 3a is connected, a plurality of the air supply boxes 42 are installed on the box 41 and are spaced apart on the box 41 along the length direction of the box 41, and an air supply hole 421 connected to the second box chamber 413b is provided at the connection between each of the air supply boxes 42 and the box 41, and a plurality of exhaust nozzles 422 connected to the interior are protruded from the side of the outer wall of the air supply box 42 away from the air supply hole 421, so that the fresh air entering the static pressure wind box can be evenly discharged from various places in the breeding layer through the plurality of air supply boxes, thereby avoiding the problem of insufficient fresh air supply in some parts.

[0045] like Figure 6 and Figure 7 As shown, in the above technical solution, the multiple air holes 4121 are spaced apart on the dividing plate 412 along its length direction, so that the air intake of each air supply box is relatively uniform; the static pressure wind box 4 also includes a plurality of baffles 414, and the multiple baffles 414 are spaced apart in the length direction of the box 41 in the second box chamber 413b, and the multiple baffles 414 correspond one by one to the multiple air holes 4121, and the air supply holes and the air holes are located on the same side of the baffles, so that the fresh air sent into the second box chamber by each air hole can be evenly distributed in the second box chamber under the buffering effect of the baffles, and then enters the air supply box through the air supply holes, thereby ensuring that the wind pressure in each air supply box is relatively consistent.

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

[0047] like Figure 6 andFigure 7 As shown, in the above technical solution, the box 41 is horizontally arranged, and its cross-section is square. The partition plate 412 is vertically inclined and arranged inside the box 41. The first chamber 413a is located above the partition plate 412, and the second chamber 413b is located below the partition plate 412 (taking the partition plate as an example of being vertically inclined, the side inclined upward corresponds to the first chamber, and vice versa, the side inclined downward corresponds to the second chamber). The air inlet interface 411 is arranged at the upper end of the box 41, and the air supply box 42 is arranged at the lower end of the box 41. The baffle plate 414 is vertically inclined and arranged inside the second chamber 413b. The upper end of the baffle plate 414 is connected to the partition 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 holes 421 and ventilation holes 4121 are located on the same side of the corresponding baffle plate 414. Its structure is simple, and there is a certain angle between the ventilation holes and the corresponding air supply holes. The baffle plate plays a role of guiding the airflow between the two.

[0048] As Figures 5 - 7 and Figure 9 shown, preferably, a middle part of the upper end of the box 41 protrudes to form an air inlet cavity 415 communicating with the inside of the first chamber 413a, and the air inlet interface 411 is arranged at the upper end of the air inlet cavity 415 (the air interface is communicated with the inside of the air inlet cavity); further preferably, a plurality of baffle plates 416 can be vertically arranged at the middle position inside the first chamber 413a. The baffle plates 416 are arranged along the width direction of the box inside the first chamber 413a, and the plurality of baffle plates 416 are spaced along the length direction of the box 41 inside the first chamber 413a. A plurality of ventilation holes 4161 are arranged at intervals along the length direction of the baffle plates 416. In this embodiment, there is a gap between the upper end of the baffle plate 416 and the top wall of the box 41 for the airflow to pass through.

[0049] As Figure 1 、 Figure 2 and Figure 12 shown, in the above technical solution, a sump fan 7 is also arranged at the connection of each ventilation duct 122 and the exhaust duct 5, so that the suction effect on the odor in the manure pit at the ventilation duct is stronger.

[0050] As 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 that are connected in sequence along the fresh air conveying direction. The air outlet of the fresh air fan 24 constitutes the air outlet of the fresh air treatment device 2. In this way, the first filter can filter the fresh air entering the fresh air treatment device. In summer, the fresh air in the wet curtain box cools the air, and in winter, the heating box heats and warms the fresh air, thereby realizing the regulation of the room temperature of the breeding layer. The fresh air fan provides power for the conveyance of fresh air.

[0051] In this embodiment, the filter element in the first filter can be divided into multiple layers, which can be, in sequence along the fresh air conveying direction, a filter screen (which can be a filter screen of about 100 - 200 meshes), a calcium chloride filling layer, and an activated carbon filling layer. Among them, calcium chloride has good adsorption and sterilization properties, which can prevent harmful bacteria from being sent into the breeding layer. The wet curtain box in this embodiment belongs to the prior art. An air source heat pump can be provided as a heating element in the heating box in this embodiment. In summer, the wet curtain box and the fresh air fan are combined to form a wet curtain fan cooling device (the heating box does not operate), and in winter, the heating box and the fresh air fan are combined to form a hot air supply device (the wet curtain box does not operate).

[0052] As Figure 11 As shown, the exhaust gas treatment device 6 in the above technical solution includes a spray box 61, a spray head 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 communicated with the air inlet of the spray box 61. The spray head 62 is arranged in the spray box 61. The second filter 64 is arranged at the air outlet of the spray box 61. The water pump 65 is arranged in the spray box 61 and is communicated with the spray head 62. In this way, the exhaust gas is powered by the exhaust gas fan and first undergoes deodorization treatment in the spray box, and then is 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. Specifically, in this embodiment, the spray box is horizontally arranged, with its two ends being the air inlet and the air outlet respectively. The lower end of the spray box can be recessed downward below the spray head to form a liquid accumulation tank 611. Multiple spray heads can be arranged, and all of them are spray nozzles. In this way, the mist liquid sprayed by multiple spray heads can form a mist wall in the spray box, and the liquid accumulation tank can be tightly located directly below the mist wall. The liquid sprayed by the spray head can be a deodorizing liquid (disinfectant can also be added to the deodorizing liquid as needed). The water pump can be a submersible pump, which is arranged in the liquid accumulation tank. The liquid outlet of the water pump is communicated with the spray head. The second filter can be directly formed by stacking multiple layers of plastic filter screens or metal wire meshes (which can block the penetration of liquid mist). The deodorizing liquid in the liquid accumulation tank can be replaced regularly (a liquid adding port and a liquid discharging port can be arranged at the liquid accumulation tank, and valves can be arranged at both the liquid adding port and the liquid discharging port. This belongs to the prior art and will not be elaborated here).

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

[0054] As Figure 1 shown, in this embodiment, each breeding layer of the building body can be divided into a breeding area 20 and a corridor area 10 (the corridor area and the breeding area are not distinguished in the overhead floor). Among them, stairs or elevators can be set in the corridor area, and except for adding access doors, the breeding area and the corridor area are in a closed state, and only one breeding area can be set on each breeding layer.

[0055] For the air supply channel, its corresponding air shaft 13 is the main air supply road, and the static pressure air boxes on each breeding layer are respectively connected to the corresponding air shaft through pipelines. For the exhaust air channel, its corresponding air shaft is the main exhaust air road, and the air inlet of the waste gas treatment device is connected to the upper end of the corresponding air shaft. Each floor drain fan can be directly installed at the connection between the ventilation duct and the corresponding air shaft. Among them, the air shaft corresponding to the exhaust air channel can be located at a position of the building body close to the corridor area, while the air supply channel can be located at a position on the side of the building body far from the corridor area. Among them, the branch passageways of the exhaust air channel and the air supply channel can both adopt PVC pipes.

[0056] As Figure 3 、 Figure 7 、 Figure 9 and Figure 12 shown, in this embodiment, two air inlet interfaces 411 can be set on the air inlet of the static pressure air box 4. At this time, each static pressure air box 4 is connected to the corresponding air shaft 13 through two air inlet branch pipes 31. And one of the air inlet branch pipes 31 can be laid in the corresponding ventilation duct 122, and switching valves 32 are arranged on both of the two air inlet branch pipes 31. The two air inlet branch pipes can be respectively the first air inlet branch pipe 31a and the second air inlet branch pipe 31b. Among them, the second air inlet branch pipe 31b passes through the ventilation duct. In this way, the switching valve on the second air inlet branch pipe 31b can be closed in summer, and the switching valve on the first air inlet branch pipe can be opened. While in winter, the switching valve on the second air inlet branch pipe 31b can be opened, and the switching valve on the first air inlet branch pipe can be closed. In this way, the heat in the waste gas can be fully utilized to preheat the fresh air passing through the second air inlet branch pipe, thereby reducing the heat loss in the indoor of the pig breeding layer in winter, and the overall energy consumption of the entire building body can be reduced (in spring and autumn, the static pressure air box can flexibly select whether to intake air through the first air inlet branch pipe or the second air inlet branch pipe according to the temperature conditions).

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

[0058] Embodiment 2

[0059] As Figure 13 and Figure 14 shown, similar to Embodiment 1, the difference is that two breeding areas 20 can also be set on each breeding layer, and the corridor area 10 is located between the two breeding areas 20. At this time, two sets of fresh air treatment devices, air supply channels and exhaust channels can be set, while only one waste gas treatment device can be shared.
