Among them, in the high-density aquaculture system of circulating water, there are problems such as low water exchange rate, small oxygen increase, insufficient aeration, and low pH. The dissolved carbon dioxide produced by the respiration of fish will gradually accumulate to a level that makes the fish and the biological filtration system face toxicity; other dissolved gases that also have a great impact on the operation of the system: nitrogen, argon, hydrogen sulfide, and methane, ammonia and radon in certain special environments. These harmful gases need to be discharged from the aquaculture water as soon as possible to reduce the impact on fish.

[0036] like Figures 1 to 3 As shown, this embodiment provides a degassing device for discharging harmful gases in water and then using them in the aquaculture system to achieve recycling. The degassing device provided in this embodiment is easy to install, has low construction and maintenance costs, and has high degassing efficiency.

[0037] The degassing device includes a tank body 100, a filler 200, a negative pressure fan 400 and a water distribution pipe 300. After the tank body 100 is built, it is only necessary to fill the tank body 100 with the filler 200 and install the negative pressure fan 400 on the secondary closure of the tank body 100 to complete the installation of the degassing device.

[0038] The pool body 100 is a civil engineering structure. In this embodiment, it is a rectangular pool body 100. It adopts a civil engineering structure and does not require welding of a stainless steel square tube frame structure, so the construction cost is low. Side sealing plates do not need to be made, and there is no lifting operation, which consumes less manpower and material resources.

[0039] The filler 200 is filled in the pool body 100 . The filler 200 is used to increase the surface area of ​​the water body when the water body passes through the filler 200 . The degassing operation is completed when the water body drips through the filler 200 .

[0040] The negative pressure fan 400 is installed on the side wall of the pool body 100. The negative pressure fan 400 includes an air inlet (not shown in the figure) and an air outlet 401. The air inlet is connected to the interior of the pool body 100, and the air outlet 401 is connected to the external environment. The negative pressure fan 400 is used to suck the gas in the water dripping through the filler 200 from the air inlet and discharge it through the air outlet 401, thereby completing the degassing of the water.

[0041] The water distribution pipe 300 is installed on the pool body 100 and is located above the filler 200 . The water distribution pipe 300 is used to evenly distribute the water that needs to be degassed on the filler 200 .

[0042] When in use, the water that needs to be degassed enters the water distribution pipe 300 through the main pipe 500. The water distribution pipe 300 evenly distributes the water above the filler 200. The undegassed water increases its specific surface area in the process of passing through the filler 200. At this time, the negative pressure fan 400 starts to work, and harmful gases such as carbon dioxide and hydrogen sulfide in the water are sucked in from the air inlet, and then discharged through the exhaust port 401. The exhaust port 401 is externally connected to a pipe, and the pipe discharges the gas to the outside, thereby achieving the purpose of degassing; the degassed water enters the biological pool for further biochemical reaction, and then re-enters the breeding pond after oxygenation and disinfection, thereby realizing water recycling and reducing the waste of water resources.

[0043] like Figure 3 As shown, the bottom of the pool body 100 includes a plurality of beams 101, and there are gaps between the beams 101, and the gaps are used to discharge the degassed water into the biological pool. Compared with the pipe drainage method, this method not only reduces the laying of pipes, reduces costs, but also can quickly discharge water.

[0044] The size of the filler 200 needs to be larger than the diameter of the gap between the beams 101. The filler 200 uses a grid square filler. The grid square filler has the following advantages: first, it increases the specific surface area of ​​the water body, and second, it can effectively attach microorganisms, which not only improves the removal efficiency of harmful gases, but also can use biofilm to decompose harmful substances such as ammonia nitrogen and hypochlorite in water. In this embodiment, a standard grid square filler is used, with a specification of 500*500*500mm cubes, so the spacing between the beams 101 needs to be less than 500mm, which can prevent the filler 200 from falling from the gap between the beams 101 and affecting the normal operation of the degassing device.

[0045] like Figure 1 , Figure 2As shown, the water distribution pipes 300 include a plurality of pipes, and in this embodiment, the pipes include 5 pipes. The 5 pipes 300 are evenly arranged above the filler 200. The plurality of water distribution pipes 300 can more evenly distribute the water on the filler 200. The pipe wall of the water distribution pipe 300 is provided with a plurality of water distribution holes 301. The water distribution pipe 300 is horizontally arranged, and the water distribution holes 301 are evenly arranged on the upper half of the pipe wall of the water distribution pipe 300. The water distribution holes 301 located on the upper half of the pipe wall can better control the flow rate, so that the water output is uniform.

[0046] The air inlet of the negative pressure fan 400 is arranged near the bottom of the side wall of the pool body 100, and can be arranged at 1 / 3 of the side wall of the pool body 100 near the bottom. Because the water body drips through the filler 200 for a longer time, the water body can be more fully broken up, which increases the specific surface area of ​​the water body, and harmful gases are more easily replaced and then sucked away by the negative pressure fan 400.

[0047] Generally, the height of the water in the pool body 100 is lower than the height of the water distribution pipe 300. However, in order to prevent the water from overflowing from the connection between the water distribution pipe 300 and the pool body 100 due to excessive height, a water stop ring is provided at the connection between the water distribution pipe 300 and the pool body 100.

[0048] In one aspect, the utility model provides an aquaculture system, comprising the degassing device as described above. The aquaculture system uses the degassing device, which has high degassing efficiency and good degassing effect, so that the water body can be recycled and the waste of water resources is reduced.

[0049] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents.
