Description

Technical Field

[0001] This utility model relates to the field of pig farming and waste gas treatment technology, specifically to a deodorization system suitable for multi-story pig houses. Background Technology

[0002] With the rapid development of large-scale and centralized livestock farming, the demand for waste gas treatment in pigsties is also gradually increasing. Especially in multi-story (double-story) pigsties, due to the high stocking density and high waste gas emissions, the requirements for deodorization systems are even more stringent.

[0003] Currently, spray deodorization is commonly used to treat pigsty exhaust gases. Conventional pigsty spray deodorization systems typically employ centralized deodorization, directing exhaust gases from the entire pigsty into a single system for treatment. However, this method has drawbacks. If a pen within the pigsty does not house the required number of pigs, the entire spray deodorization system still needs to operate to meet deodorization requirements, resulting in higher exhaust gas treatment costs.

Therefore, they should not be construed as limitations on this utility model.

[0038] Example 1:

[0039] This embodiment uses a double-layered pigsty as an example to demonstrate a deodorization system.

[0040] like Figure 1 As shown, in this embodiment, the pigsty 1 has two floors and contains multiple pig pens. All pig pens are arranged along the wind wall 11, and multiple deodorization rooms 2 are arranged on the outside of the wind wall 11. Each deodorization room 2 corresponds to one pig pen unit. Specifically, the deodorization room 2 is also connected to the manure ditch below the pig pen unit.

[0041] A fan 12 is installed on the air wall 11. The fan 12 is used to exhaust the gas in the pigsty to the deodorization room 2. The deodorization room 2 is equipped with a first spray unit 21, a second spray unit 22, a deodorization filter layer 23 and a third spray unit 24. The first spray unit 21, the deodorization filter layer 22 and the second spray unit 22 are arranged in sequence along the air outlet direction of the fan 12. The third spray unit 24 is located above the deodorization filter layer 22. The spray nozzles of the first spray unit 21, the second spray unit 22 and the third spray unit 24 all face the deodorization filter layer 23.

[0042] The first spray unit 21 sprays air along with the deodorizing filter layer 23, which can adsorb dust in the exhaust gas onto the surface of the deodorizing filter layer 23; the second spray unit 22 sprays hypochlorous acid solution onto the deodorizing filter layer 23, thereby reacting chemically with ammonia and nitrogen elements in the exhaust gas to reduce odor; the third spray unit 24 sprays above the deodorizing filter layer 23 to clean the impurities attached to the deodorizing filter layer 23.

[0043] like Figure 6 and Figure 7 As shown, it includes two sets of water supply systems 3 and hypochlorous acid supply systems 4, which are used to supply water and hypochlorous acid solution to the deodorization rooms on the first and second floors, respectively. Both water supply systems 3 and hypochlorous acid supply systems 4 are set on the first floor of pig house 1. This arrangement can greatly reduce the load-bearing requirements of the second floor of pig house and reduce construction costs.

[0044] like Figure 4 As shown, specifically, the water supply system 3 includes a water collection tank 31, a first pump 32, a first control valve 33, and a second control valve 34. The first pump 32 is used to transport water in the water collection tank 31 to the first spray unit 21 and the third spray unit 24 in each deodorization room 2. A first control valve 33 is provided between the first pump 32 and each deodorization room 2, and a second control valve 34 is provided between the first control valve 33 and the corresponding first spray unit 21 and third spray unit 24.

[0045] Hypochlorous acid supply system 4 includes a liquid tank 41, a second pump 42 and a third control valve 43. The second pump 42 is used to transport the hypochlorous acid solution in the liquid tank 41 to the second spray unit 22 in each deodorization room 2. A third control valve 43 is provided between the second pump 42 and each second spray unit 22.

[0046] The control terminal 5 is electrically connected to all the first pumps 32, first control valves 33, second control valves, second pumps 42, third control valves 43, air wall fans 12, and sewage pumps 61, and the connection method is wireless or wired. The control terminal 5 is used to realize the opening / closing of the above-mentioned components and the power adjustment. The control terminal can be specifically adjusted to the corresponding components of the corresponding deodorization room 2 (for example, if the number of pigs in one of the pig pens is small, the control terminal 5 will reduce the wind speed of the corresponding air wall fan 12 and reduce the spray volume of the first spray unit 21, the second spray unit 22, and the third spray unit 24 in the corresponding deodorization room 2, that is, adjust the flow rate through the corresponding first control valve 33, the second control valve 34, and the third control valve 43). It should be noted that this embodiment is intended to disclose the connection relationship of each component so that those skilled in the art can clearly implement the solution of this application. The above control method is a conventional control method in the art. Those skilled in the art can implement the above control method according to existing control programs and computers (or PLCs), so it will not be described in detail.

[0047] Example 2:

[0048] This embodiment is an improvement on the first embodiment, and the improvements involve the first spray unit 21, the second spray unit 22 and the third spray unit 24.

[0049] In this embodiment, as Figure 2 As shown, the first spray unit 21 includes five rows of spiral nozzles 2a arranged sequentially from bottom to top, with adjacent rows of spiral nozzles 2a staggered left and right.

[0050] like Figure 3 As shown, the second spray unit 22 includes three rows of atomizing nozzles 2b arranged sequentially from bottom to top, with adjacent rows of atomizing nozzles 2b staggered left and right.

[0051] Furthermore, the spray area of ​​the spiral nozzle 2a is smaller than that of the atomizing nozzle 2b, and the vertical spacing between two adjacent rows of spiral nozzles 2a is smaller than that between two adjacent rows of atomizing nozzles 2b.

[0052] The height of the first spray unit 21 and the second spray unit 22 is 3m, and the lateral spacing between two adjacent spiral nozzles 2a and the lateral spacing between two adjacent atomizing nozzles 2b is 1m.

[0053] The deodorizing filter layer 23 is 3m high and is made of 450mm thick PP material deodorizing filler.

[0054] The third spray unit 24 consists of a row of spiral nozzles 2a.

[0055] Both the spiral nozzle 2a and the atomizing nozzle 2b have frequency conversion function, which can adjust the spray flow as needed. The atomizing nozzle 2b is detachable, which is convenient for disassembly and maintenance.

[0056] Example 3:

[0057] This embodiment is an improvement on the first embodiment, and the improvement involves the structure of the deodorization room 2.

[0058] In this embodiment, the floor of the deodorization room 2 has a certain slope, and the deodorizing water will converge to the drain outlet 26 through the slope. The deodorizing water of the second-floor deodorization room 2 will be guided to the drain outlet 26 of the first-floor deodorization room 2 through the drain pipe 27, and then discharged to the first-floor water collection tank 31 after passing through a filter unit (not shown in the figure).

[0059] The bottom of the water collection tank 31 is reserved with a foundation pit for installing a sewage pump 61 to realize the drainage and sewage discharge of the water collection tank 31. The water collection tank 31 is also equipped with a level gauge to detect the liquid level height of the water collection tank 31, so as to facilitate drainage / replenishment of the water collection tank 31 according to the liquid level height.

[0060] The water and hypochlorous acid solution used for deodorizing spraying will be returned to the collection tank through the drainage system, and after filtration, they will be used for water spraying, which can save water and chemicals.

[0061] An inspection ladder 62 is installed between adjacent deodorization rooms 2. The inspection ladder 62 is used by staff to access the second floor of the pigsty to inspect the equipment in the deodorization rooms.

[0062] Example 4:

[0063] This embodiment is an improvement on the first embodiment, and the improvement involves the structure of the deodorization room 2.

[0064] Unlike Embodiment 3, in this embodiment, the drainage tank 25 is independent of the water collection tank 31. The drainage tank 25 is used to collect the deodorized water discharged from the first-floor deodorization room 2, as well as the deodorized water discharged from the second-floor deodorization room 2 that is transported through the drainage pipe 27.
