Description

Technical Field

[0001] This application relates to the field of aquaculture water treatment, and in particular to a large-flow-rate water degassing device. Background Technology

[0002] Degassing is essential in aquaculture primarily because dissolved gases in the water (such as oxygen and carbon dioxide, especially carbon dioxide) can become supersaturated under certain conditions. When water temperature changes, pressure drops, or water quality deteriorates, supersaturated gases may be released rapidly, causing gas bubbles to form in fish and other aquatic organisms. This condition, known as "gas bubble disease," can severely impact their health and even be fatal. Furthermore, high concentrations of carbon dioxide can affect the pH of the water, making the aquatic environment acidic. This is detrimental to fish respiration and growth, potentially increasing the incidence of fish diseases.

[0003] Various degassing devices are used in existing aquaculture processes, but these devices often cannot meet the needs of large-scale, high-flow-rate water applications in actual use. To address this, some process implementers in existing solutions use multiple degassing devices at the same time, which undoubtedly leads to increased production costs.

[0004] In summary, how to propose a water degassing device suitable for large-scale, high-flow-rate scenarios has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In order to carry out water degassing treatment efficiently and at low cost in large-scale, high-flow aquaculture scenarios, this application provides a high-flow water degassing device.

[0006] A high-flow-rate water degassing device includes an inlet assembly, a packing chamber, and a liquid collection chamber. The packing chamber is used to place packing material and is connected to the inlet assembly. The liquid collection chamber is located below the packing chamber and is connected to it. A water outlet structure is provided on the inner wall of the liquid collection chamber. A support assembly for supporting the packing material is provided on the upper part of the liquid collection chamber. A flow guiding mechanism for accelerating the water flow rate is installed at the lower end of the support assembly. The flow guiding mechanism includes a liquid guiding inclined plate and a liquid separating assembly. The liquid guiding inclined plate is inclined, and the lower end of the liquid guiding inclined plate is close to the water outlet structure. The liquid separating assembly is located above the liquid guiding inclined plate and there is a gap between the liquid separating assembly and the liquid guiding inclined plate for water to flow through.

[0007] By adopting the above-mentioned technical means, setting up liquid guide ramps and liquid separation components, the speed at which water flows to the outlet structure is accelerated, thereby improving the overall operating efficiency of the equipment and meeting the requirements of large-volume, large-scale water degassing.

[0008] Preferably, the packing cavity is further provided with a ventilation assembly, which includes a plurality of ventilation pipes with equal spacing and an air source device installed at the top of each ventilation pipe.

[0009] By employing the above-mentioned technical means and setting up ventilation components, the air source equipment increases the contact between the generated wind and the water, accelerates the flow rate of the water entering the packing chamber, improves the degassing effect, and increases the degassing rate. At the same time, the air source equipment continuously inputs gas into the ventilation pipe. As the gas rises, it fully contacts the falling water, thereby more effectively removing dissolved gases from the water and improving the degassing effect.

[0010] Preferably, the water inlet assembly includes a water inlet, a main water inlet pipe connected to the water inlet, and several parallel water inlet branch pipes. The water inlet and the main water inlet pipe are located outside the packing cavity, and the water inlet branch pipes are located inside the packing cavity.

[0011] All the inlet branch pipes are parallel to each other and installed above the packing. One end of the inlet branch pipe passes through the cavity wall of the packing cavity and is connected to the main inlet pipe, while the other end is fixedly connected to the cavity wall on the opposite side of the packing cavity. Each inlet branch pipe has multiple outlet holes with the same spacing evenly opened.

[0012] By employing the above-mentioned technical means, multiple water inlet branch pipes are set above the packing material to ensure that the water can enter the packing cavity more evenly and stably, and fully contact the packing material, providing good conditions for subsequent degassing treatment and improving the degassing effect. At the same time, multiple water outlet holes are evenly opened in the water inlet branch pipes, which further disperses the water flow on the basis of the above-mentioned water dispersion, making the water disperse more completely, thereby achieving a better degassing effect.

[0013] Preferably, a vent pipe is provided between every two water inlet branch pipes along the direction of gravity, and the vent pipe is perpendicular to the water inlet branch pipe.

[0014] By employing the aforementioned technical means, the vent pipes are evenly distributed among all the water inlet branch pipes, ensuring uniform air blowing into the water body and guaranteeing the degassing effect and rate.

[0015] Preferably, the packing is placed in the packing area of ​​the packing cavity, the packing area comprising multiple horizontally arranged packing layers, each packing layer comprising multiple parallel rod-shaped packings, and every two packing layers are arranged in a crisscross pattern.

[0016] By employing the aforementioned technical means and setting up multiple layers of crisscrossing rod-shaped packing, the water flow can be dispersed, increasing the contact area between the water and the rod-shaped packing, thereby making it easier for gas in the water to escape, improving the degassing effect of the water, and also increasing the dissolved oxygen efficiency of the water.

[0017] Preferably, a detachable packing baffle is provided on the side of the packing cavity.

[0018] By adopting the above-mentioned technical means, a detachable baffle is set in the packing bin to facilitate the replacement or maintenance of the packing. If it cannot be detached, it will be very troublesome to replace the packing if it becomes clogged. The above-mentioned technical solution improves the practicality of the equipment.

[0019] Preferably, the liquid separation assembly includes a first separation plate and a second separation plate that are parallel to each other. The left and right ends of the first separation plate and the second separation plate are fixedly connected to the inner wall of the liquid collection chamber. The second separation plate is located between the water outlet structure and the first separation plate. The gap width formed between the lower end of the first separation plate and the upper end face of the liquid guide plate is greater than the gap width formed between the lower end of the second separation plate and the upper end face of the liquid guide plate.

[0020] By employing the aforementioned technical means and setting up a first and a second partition plate, the water falling into the collection chamber can be divided in two stages. The water first flows through the gap under the first partition plate and then through the smaller gap under the second partition plate. Through the decreasing gap width, the flow rate of the water can be gradually increased, further increasing the rate at which the water flows towards the outlet, thereby improving the overall degassing efficiency of the equipment and meeting the dewatering needs under large-scale and high-flow conditions.

[0021] Preferably, the top of the liquid collection chamber is provided with a gas outlet, which is connected to the outside.

[0022] By adopting the above-mentioned technical means, the gas in the water flowing through the packing chamber will be discharged from the gas outlet under the wind force generated by the gas source equipment. The gas is discharged from the equipment in a timely manner through the gas outlet, avoiding the accumulation of gas in the equipment, which may affect the water degassing effect.

[0023] Preferably, the water outlet structure includes a first water outlet and a second water outlet, and the highest water outlet levels of the first water outlet and the second water outlet are at the same horizontal height;

[0024] The bottom end of the liquid collection chamber is also connected to an overflow pipe, which is located between the first outlet and the second outlet. The overflow inlet of the overflow pipe is located inside the liquid collection chamber, and the horizontal height of the overflow inlet is higher than the height of the highest outlet level.

[0025] By adopting the above-mentioned technical means, and setting up a water outlet structure including a first outlet and a second outlet, as well as an overflow pipe located between the two, it can be ensured that the equipment maintains a stable water level during operation, avoiding the impact on the normal operation of the equipment due to excessively high or low water levels; and the horizontal height of the overflow inlet is made higher than the height of the highest outlet water level to prevent the overflow pipe from becoming ineffective.

[0026] Preferably, the air source device is a fan.

[0027] In summary, this application has at least the following beneficial effects:

[0028] (1) This application achieves effective guidance of water in the collection chamber through liquid guide inclined plate and liquid separation component, which accelerates the flow of water to the water outlet structure, thereby improving the overall operating efficiency of the equipment and meeting the needs of large flow and large scale water degassing. At the same time, by setting multiple water inlet branch pipes and air pipes, it can adapt to water with different flow rates and velocities, ensuring the degassing effect while meeting the needs of large scale water degassing, which has significant practical value and broad market prospects.

[0029] (2) This application sets up multi-layer overlapping rod packing, which increases the contact area between the water and the packing, effectively disperses the water flow, promotes the separation of gas and liquid, and makes it easier for gas in the water to escape. At the same time, it works with the ventilation component to promote the discharge of gas and further improve the degassing efficiency.

[0030] (3) The present application provides a detachable baffle plate on the side of the packing cavity, which makes the replacement and cleaning of the packing convenient and reduces maintenance costs; at the same time, the equipment structure is relatively simple and easy to operate and manage.

[0037] Exemplary embodiments of this disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art.

[0038] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0039] This application provides a high-flow-rate water degassing device, which adopts the following technical solution:

[0040] like Figure 1 As shown, it includes a water inlet assembly, a packing chamber 1, and a liquid collection chamber 2.

[0041] The packing cavity 1 is used to place the packing material. In this embodiment, the packing material is a rod-shaped packing material 12. The packing cavity 1 is provided with a packing area, and the rod-shaped packing material 12 is placed in the packing area.

[0042] Specifically, such as Figure 2 As shown, the packing zone consists of multiple horizontally arranged packing layers, and each packing layer consists of multiple parallel rod-shaped packings 12. These rod-shaped packings 12 are arranged in a crisscross pattern between adjacent packing layers.

[0043] This staggered layout ensures sufficient contact between water and air while avoiding mutual interference. It can more effectively disperse the water flow, making it easier for gas in the water to escape, thereby improving degassing efficiency.

[0044] Of course, in other implementation schemes, the packing material can also be designed into other shapes as needed, as long as it can disperse the water flow and promote the escape of gas.

[0045] The packing chamber 1 is connected to the water inlet assembly, allowing water to smoothly enter the packing chamber 1 through the water inlet assembly.

[0046] like Figure 3 As shown, in this embodiment, the water inlet assembly includes a water inlet 8, a main water inlet pipe 9 connected to the water inlet 8, and several parallel water inlet branch pipes 10. The water inlet 8 and the main water inlet pipe 9 are disposed outside the packing cavity 1. Specifically, the main water inlet pipe 9 is fixedly installed on the outer wall of the packing cavity 1.

[0047] like Figure 2 As shown, the water inlet branch pipes 10 are disposed inside the packing cavity 1. All the water inlet branch pipes 10 are parallel to each other and installed above the packing. As shown in the figure, in this embodiment, there are 6 water inlet branch pipes 10, which are evenly distributed above the uppermost packing layer and do not contact the packing layer. One end of each water inlet branch pipe 10 passes through the cavity wall of the packing cavity 1 and is connected to the main water inlet pipe 9, and the other end is fixedly connected to the cavity wall on the opposite side of the packing cavity 1. Each water inlet branch pipe 10 has a plurality of outlet holes 11 evenly spaced.

[0048] After the water flows out of the outlet holes 11 of the multiple inlet branch pipes 10, it can enter the rod-shaped packing material 12 below under the action of gravity. The multiple inlet branch pipes 10 can accommodate a larger water flow rate. The uniform distribution of the inlet branch pipes 10 and the evenly distributed outlet holes 11 on the inlet branch pipes 10 also ensure that the water can enter the packing area uniformly and stably, providing good conditions for subsequent degassing treatment.

[0049] Inside the packing chamber 1, a ventilation assembly is also provided, which includes several ventilation pipes 6 with equal spacing and an air source device 7 installed at the top of each ventilation pipe 6.

[0050] In this embodiment, the air source device 7 is a fan. In other feasible embodiments, the air source device can also be an air pump or other device that can provide air power.

[0051] The aforementioned vent pipes 6 are evenly distributed within the packing cavity 1. A vent pipe 6 is provided between every two water inlet branch pipes 10 along the direction of gravity. In this embodiment, there are 5 vent pipes 6, and the vent pipes 6 are perpendicular to each other with respect to the water inlet branch pipes 10.

[0052] A fan is fixed above the vent pipe 6, and the lower port faces the packing area below.

[0053] The vent pipe 6 and the water inlet branch pipe 10 work together to form a three-dimensional water-air exchange structure. The blower continuously supplies gas into the vent pipe 6. This gas enables the water to pass through the packing area more quickly, ensuring the efficiency of water flow. Furthermore, the gas makes full contact with the falling water, which can more effectively remove the gas to be degassed from the water, ensuring the degassing effect.

[0054] The liquid collection chamber 2 is located below the packing chamber 1 and is connected to the packing chamber 1. It is used to collect the water after it has been dispersed by the packing.

[0055] It should be noted that, as Figure 3 As shown, in this embodiment, the floor area of ​​the packing chamber 1 and the liquid collecting chamber 2 are different. The liquid collecting chamber 2 is located below, and the packing chamber 1 is stacked on top of the liquid collecting chamber 2. The floor area of ​​the packing chamber 1 is smaller than that of the liquid collecting chamber 2. In this embodiment, the floor area is the top view area. Therefore, a part of the top area of ​​the liquid collecting chamber 2 is not blocked by the packing chamber 1. This part of the top is open and communicates with the outside. The open position serves as the gas outlet 16 for discharging the gas that has escaped.

[0056] The gas outlet 16 ensures that the degassed gas can be discharged to the outside of the equipment in a timely manner, avoiding the accumulation of gas inside the equipment and affecting the degassing effect.

[0057] In one feasible embodiment, a removable packing baffle 13 is provided on the side of the packing chamber 1. The packing baffle 13 facilitates equipment maintenance and allows for easy removal and replacement of the packing in case of packing blockage.

[0058] A support assembly 4 is provided at the upper part of the liquid collection chamber 2. The main function of the support assembly 4 is to support the packing and ensure that the packing can be stably placed in the packing chamber 1.

[0059] like Figure 2 As shown, the support component 4 in this embodiment consists of four support plates 41. The two ends of the support plates 41 in the long axis direction are fixedly installed on the inner wall of the liquid collection chamber 2, so that each support plate 41 can support the rod-shaped packing 12 in the packing chamber 1 above it, thus ensuring the stability of the packing layer.

[0060] A water outlet structure 3 is provided on the inner wall of the liquid collection chamber 2 so that the treated water can be discharged smoothly.

[0061] A flow guiding mechanism is installed at the lower end of the support component 4. The flow guiding mechanism includes a liquid flow guiding inclined plate 5 and a liquid separation component. The liquid flow guiding inclined plate 5 is fixedly installed at the bottom of the liquid collection chamber 2 and is inclined. The lower end of the liquid flow guiding inclined plate 5 is close to the water outlet structure 3. The purpose of this arrangement is to use the guiding effect of the liquid flow guiding inclined plate 5 to allow the water to flow more naturally and quickly to the water outlet structure under the action of gravity.

[0062] Specifically, such as Figure 2 As shown, the liquid separation component is fixedly installed above the liquid guide plate 5, and there is a gap between the component and the liquid guide plate 5 for water to flow through. This gap not only ensures that the water can flow smoothly, but also accelerates the water flow velocity to a certain extent.

[0063] Specifically, the liquid separation assembly includes a first separation plate 14 and a second separation plate 15 that are parallel to each other. The left and right ends of the first separation plate 14 and the second separation plate 15 are fixedly connected to the inner wall of the liquid collection chamber 2. The first separation plate 14 and the second separation plate 15 are parallel to each other and their long axis direction is perpendicular to the long axis direction of the support plate 41. They are snapped into the support plate 41. This structure can further ensure the stability of the first separation plate 14 and the second separation plate 15 in the liquid collection chamber 2. When the equipment is working, it can prevent the structure of the two from being damaged by the impact force generated by excessive water flow.

[0064] like Figure 4 As shown, the second partition plate 15 is located between the water outlet structure 3 and the first partition plate 14, and the gap width formed between the lower end of the first partition plate 14 and the upper end face of the liquid guide plate 5 is greater than the gap width formed between the lower end of the second partition plate 15 and the upper end face of the liquid guide plate 5.

[0065] After the water falls from the packing chamber 1 into the liquid collection chamber 2, most of the water first passes through the larger gap between the first partition plate 14 and the liquid guide inclined plate 5, and then through the smaller gap between the second partition plate 15 and the liquid guide inclined plate 5. This allows the water to gradually increase its flow rate as it passes through these two gaps in sequence, thereby improving the overall operating efficiency of the equipment and enabling the equipment to accommodate a larger water flow rate within a certain period of time, thus achieving large-scale water degassing.

[0066] Furthermore, in a feasible specific solution, the water outlet structure 3 was optimized. The water outlet structure 3 includes a first water outlet 31 and a second water outlet 32. The highest water outlet level of the first water outlet 31 and the second water outlet 32 ​​are at the same horizontal height, which ensures that the equipment can stably output the treated water to the outside during operation. The two water outlets can also alleviate the problem of water outlet blockage.

[0067] like Figure 2As shown, the bottom of the liquid collection chamber 2 is also connected to an overflow pipe 17. The overflow pipe 17 is located between the first outlet 31 and the second outlet 32. When the water flow is too large, the equipment can discharge the excess water in time through the overflow pipe 17 to ensure the safe and stable operation of the equipment.

[0068] like Figure 4 As shown, the overflow inlet 18 of the overflow pipe 17 is located inside the liquid collection chamber 2, and the horizontal height of the overflow inlet 18 is higher than the height of the highest outlet water level. This can prevent overflow caused by excessive water level and ensure that the equipment is not affected by overflow during normal operation.

[0069] The implementation principle of a high-flow-rate water degassing device in this embodiment is as follows: Water enters the packing chamber 1 from the inlet 8 and the main inlet pipe 9, flows out through the outlet holes 11 of multiple inlet branch pipes 10 connected to the main inlet pipe 9, and enters the rod-shaped packing 12 below under the action of gravity. It is dispersed by the rod-shaped packing 12. At the same time, under the action of the air blower on the vent pipe 6, the downward flow speed is accelerated and it enters the liquid collection chamber 2 below the packing chamber 1. During the process of the water being dispersed by the rod-shaped packing 12, the gas to be degassed in the water escapes. The gas to be degassed is carried into the liquid collection chamber 2 below under the action of the air blower, and then escapes to the outside from the open gas outlet 16 of the liquid collection chamber 2, thus realizing the degassing of the water.

[0070] After degassing, the water volume in the liquid collection chamber 2 first passes through the larger gap between the first partition plate 14 and the liquid guide inclined plate 5, and then through the smaller gap between the second partition plate 15 and the liquid guide inclined plate 5, so that the water flow velocity gradually increases and is discharged through the first outlet 31 and the second outlet 32, achieving efficient degassing of a large flow of water.

[0071] Through the detailed description of the above embodiments, those skilled in the art can clearly understand the specific structure and implementation method of the large-flow water degassing equipment provided in this application. These embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit its scope of protection. For example, different materials or features can be selected to replace some or all of the technical features in the above embodiments according to actual needs; the technical features in the above embodiments can also be combined or separated to form new technical solutions. In short, any simple modifications, equivalent substitutions, or improvements made to the technical solutions of this application should be included within the scope of protection of this application.
