Description

Technical Field

[0001] This utility model relates to the field of water environment management technology, specifically to a device for realizing multi-source nano-aeration oxygen production. Background Technology

[0002] my country's per capita water resources are only one-quarter of the world average, and pollution is severe. Water management is a crucial measure to alleviate water scarcity and fulfill global ecological commitments. The core significance of water environment management lies in ensuring ecological security, promoting sustainable development, improving people's well-being, and fostering harmonious coexistence between the economy and nature. Furthermore, management can restore aquatic vegetation, wetlands, and other ecosystems, enhance the self-purification capacity of water bodies, and increase biodiversity, providing healthy habitats for fish and aquatic plants.

[0003] Currently, water bodies often suffer from severe oxygen deficiency in water environment management. Adding aeration equipment can improve water quality and promote the restoration of aquatic systems and the increase of biodiversity. However, existing aeration equipment typically increases the contact area between water and air, allowing more oxygen from the air to dissolve in the water to meet the oxygen requirements of aquatic organisms. However, the contact area between water and air is relatively low, and the oxygen content in the air is not high, resulting in a slow increase in the oxygen content of the water. Furthermore, traditional aeration equipment can only increase the oxygen content in the aquatic environment and cannot introduce other gases, leading to poor efficiency in water environment management. Therefore, we propose a device for multi-source nano-aeration oxygen production. Utility Model Content

[0004] The purpose of this invention is to provide a device for multi-source nano-aeration oxygen production, which has the advantages of multi-source nano-aeration and high efficiency in water environment treatment. It solves the problem that existing oxygenation equipment usually increases the contact area between water and air, so that more oxygen in the air dissolves in the water to meet the oxygen requirements of aquatic organisms. However, the contact area between water and air is low and the oxygen content in the air is not high, which makes the oxygen content in the water increase slowly. In addition, traditional oxygenation equipment can only increase the oxygen content in the aquatic environment and cannot introduce other gases, resulting in poor water environment treatment efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for generating oxygen through multi-source nano-aeration, comprising: The bottom shell has floating shells at both the front and rear ends inside, and multiple equally spaced filter holes are provided at the bottom of the bottom shell.

[0020] Please see Figures 1-6 As shown, this utility model provides a technical solution: a device for realizing multi-source nano-aeration oxygen production, comprising: The bottom shell 1 has floating shells 104 at both the front and rear ends inside the bottom shell 1, and multiple equally spaced filter holes 103 are opened at the bottom of the bottom shell 1. The cover 2 is located on the top of the bottom shell 1, and a maintenance groove 203 is provided at the right end of the top of the cover 2. Positioning brackets 6 are fixedly installed at both ends of the bottom of the inner cavity of the bottom shell 1. The bottom of the inner side of the positioning bracket 6 is fixedly installed with the pump body shell 4. The inner side of the pump body shell 4 is fixedly installed with the turbine pump body 401 through the bracket. The right end of the turbine pump body 401 is threadedly connected with the air nozzle 409. The control cabinet 5 is located on the shore. A power line 407 connects the control cabinet 5 and the turbine pump body 401. An air supply pipe 402 is provided between the air source device at the lower end of the inner cavity of the control cabinet 5 and the liquid inlet of the turbine pump body 401. An air flow control valve 403 is provided at one end of the air supply pipe 402 located inside the shell cover 2. An opening and closing control valve 410 is provided at the branch pipe end of the air supply pipe 402 near the control cabinet 5.

[0021] The left side of the bottom shell 1 has an air supply pipe hole 102 and a power supply pipe hole 105, and the inner sides of the air supply pipe hole 102 and the power supply pipe hole 105 are provided with protective rubber sleeves. Meanwhile, the power cord 407 and the air supply pipe 402 pass through the inner sides of the power supply pipe hole 105 and the air supply pipe hole 102, respectively. The right side of the pump body shell 4 has a positioning through groove 404, and the left end of the top of the pump body shell 4 has a liquid observation port 405. The right side of the bottom shell 1 has an air nozzle slot 108, and the air nozzle 40... One end of 9 passes through the inside of the air nozzle slot 108. The upper ends of the left and right sides of the bottom shell 1 are fixedly installed with handles 101. The left and right ends of the top of the bottom shell 1 are fixedly connected with positioning pins 106. The left and right ends of the bottom of the shell cover 2 are provided with mating holes 202 that are adapted to the positioning pins 106. The upper end of the positioning pins 106 is threadedly connected with a connecting cover 107. One end of the inspection slot 203 is movably connected with a protective cover 201 through a hinge, and one end of the protective cover 201 is provided with a lock body.

[0022] This technical solution: Through the cooperation of the positioning post 106 and the docking hole 202, the shell cover 2 can be placed on top of the bottom shell 1. After tightening the connecting cover 107, the shell cover 2 can be quickly installed. The handle 101 makes it easy to place the equipment into the water area that needs treatment. With the cooperation of the filter hole 103 and the floating shell 104, the water in the water area can enter the bottom shell 1 after preliminary filtration. Then, it enters the pump body shell 4 through the liquid observation port 405. At the same time, the floating shell 1... 04 ensures that the equipment can float on water. Next, connect the selected branch pipes of the power cord 407 and the air supply pipe 402 to the power control terminal and corresponding air source equipment in the control cabinet 5, respectively. Then, open the on / off control valve 410 on the corresponding branch pipe, and the control cabinet 5 will start the equipment. Then, the turbine pump body 401 draws in water through the inlet, pressurizes it, and sends it out through the outlet into the air nozzle 409. Simultaneously, the air source equipment inside the control cabinet 5 can... Gas is supplied through the gas pipeline 402 and the air flow control valve 403 into the inlet of the turbine pump body 401. Gas, along with pressurized water, is then expelled through the air nozzle 409 as nano-sized bubbles. Because the diameter of these nano-bubbles is extremely small, typically between tens and hundreds of nanometers, they possess a huge specific surface area. This significantly increases the contact area between the gas and water, improving the gas dissolution efficiency. Furthermore, the high surface tension of the nano-bubbles enhances their stability in water, allowing them to persist for extended periods without easily breaking, thus prolonging the contact time between the gas and water. Simultaneously, due to their small size and density, similar to water, the nano-bubbles rise very slowly in water, ensuring they fully contact pollutants in the water and improving aeration. The inspection tank 203 and the protective cover 201 facilitate user inspection and maintenance. The positioning frame 6 and the limiting partition 601 ensure the stability of the pump body shell 4 and the turbine pump body 401 during operation.

[0023] The working principle of this equipment when connected to pure oxygen is as follows: I. Oxygen Input and Dispersion This equipment introduces pure oxygen into its interior through a specific piping system. Special nozzles (409) are typically used within the equipment to disperse the oxygen.

[0024] High-pressure cutting: By applying high pressure, pure oxygen is forced at high speed through the tiny pores or slits of the aerator head. During this process, the pure oxygen is cut into nanoscale bubbles by intense shearing forces and turbulence. This high-pressure cutting method can generate a large number of uniform nanobubbles, increasing the contact area between oxygen and water.

[0025] Special Material Function: Some nano-aeration devices use special materials for their nozzles (409), such as ceramics or polymers with hydrophilic and microporous structures. These materials promote oxygen dispersion in water, making it easier for oxygen to form nanobubbles and fully contact the water.

[0026] II. Characteristics and Functions of Nanobubbles Large specific surface area: Nanobubbles typically have diameters ranging from tens to hundreds of nanometers, resulting in an extremely large specific surface area. This allows pure oxygen to dissolve in water with significantly higher efficiency. Compared to traditional large-bubble aeration, nanobubbles provide a larger contact interface between oxygen and water, accelerating the oxygen dissolution rate.

[0027] Surface tension and stability: Nanobubbles possess high surface tension, enhancing their stability in water. They can persist in water for extended periods without easily breaking down, thus prolonging the contact time between oxygen and water and improving oxygen utilization.

[0028] Slow ascent and deep diffusion: Nanobubbles rise very slowly in water, allowing them to penetrate deep into the bottom layers. This is crucial for the ecological management of rivers and other water bodies, as it delivers oxygen to the bottom, improving oxygen levels and promoting the decomposition of organic matter and microbial activity in the sediment.

[0029] III. Oxygen Transfer and Water Ecosystem Improvement Increased dissolved oxygen: The pure oxygen in the nanobubbles gradually dissolves into the water, significantly increasing the dissolved oxygen content. High concentrations of dissolved oxygen help promote the growth and metabolic activities of aerobic organisms in the water, such as the decomposition of organic matter by aerobic microorganisms and the photosynthesis of aquatic plants. This plays a crucial role in improving the aquatic ecological environment and enhancing the self-purification capacity of water bodies.

[0030] Enhanced oxidation: Pure oxygen has a strong oxidizing capacity, accelerating the oxidative decomposition of organic matter and reducing substances in water. Nano-aeration equipment disperses pure oxygen into the water in the form of nanobubbles, further enhancing the oxidation process. This effectively removes pollutants from the water, such as ammonia nitrogen, hydrogen sulfide, and organic matter, improving water quality.

[0031] Promoting the recovery of biological communities: High dissolved oxygen levels and good water quality are conducive to the survival and reproduction of aquatic organisms. Nano-aeration devices provide a more suitable living environment for aquatic organisms by increasing the dissolved oxygen level in the water, thus promoting the recovery and stability of biological communities in the aquatic ecosystem.

[0032] The bubbles produced by this equipment are as small as about 200 nanometers in size, with a large charge, strong interfacial adsorption, and long survival time. Because the nanoscale bubbles undergo Brownian motion in the water, the diffusion distance can reach thousands of meters. The nanobubbles have high mass transfer efficiency, long residence time, and large coverage area. The efficiency of this technology is far superior to that of conventional micron aeration technology.

[0033] This equipment generates abundant nanobubbles containing high-purity oxygen, providing oxygen to the bottom sediment layer and aquatic plants, animals, and microorganisms. Deep oxygenation promotes aerobic reactions, which release hydroxide ions, creating a slightly alkaline environment. In addition to the main equipment, small-sized interface materials are provided to provide a reaction interface for nitrifying bacteria and promote their reproduction. In this suitable aquatic environment, nitrifying bacteria will continuously consume ammonia nitrogen.

[0034] This equipment increases the dissolved oxygen in the water system of this project, which can promote the formation of an aquatic ecosystem, providing sufficient oxygen for aquatic animals and microorganisms, and making the water crystal clear.

[0035] I. Reduce ammonia nitrogen In aquatic environments, a large number of bacteria naturally exist in the overlying water and bottom sediment. Among them are nitrifying bacteria, which can convert ammonia nitrogen, thus reducing it. However, nitrifying bacteria require a suitable living environment, such as sufficient oxygen, slightly alkaline water, and suitable porous materials. Polluted water bodies or those with poor self-purification capabilities often fail to meet these conditions. "High-efficiency micro-nano aeration" technology activates nitrifying bacteria to reduce ammonia nitrogen by providing them with an excellent living environment. Specifically, the high-efficiency micro-nano aeration equipment generates abundant nanobubbles containing high-purity oxygen, providing deep oxygen to the bottom sediment layer and overlying water. This deep oxygen supply promotes aerobic reactions, which release hydroxide ions, creating a slightly alkaline environment. In addition to the main equipment, small-sized interface materials are also provided, which provide a reaction interface for nitrifying bacteria and promote bacterial reproduction. In this suitable aquatic environment, nitrifying bacteria will continuously consume ammonia nitrogen.

[0036] II. Reduce COD The reduction in COD is primarily due to the forced explosion of highly efficient micro-nano bubble water generated by the equipment within the water body, producing hydroxyl radicals. These hydroxyl radicals have extremely strong oxidizing power, efficiently oxidizing organic pollutants in the water and directly reducing COD. Additionally, the highly efficient micro-nano bubble water stimulates the activity of inherent aerobic microorganisms in the aquatic environment. These aerobic microorganisms absorb nutrients (proteins, polysaccharides, lipids, etc.) from the water, achieving the effect of degrading organic matter and reducing COD.

[0037] III. Reduce total phosphorus Anaerobic conditions will cause phosphorus in the sediment to be released into the water. The high-efficiency micro-nano aeration equipment produces oxygen-rich, high-efficiency micro-nano bubble water. Due to its extremely small size and charged effect, it can penetrate into the sediment, inhibiting anaerobic reactions and thus inhibiting the transfer of phosphorus from the sediment to the water. Obviously, it can control the total phosphorus index. In addition, the high-efficiency micro-nano bubble water environment can also activate polyphosphate-accumulating bacteria to absorb phosphate under aerobic conditions. This not only inhibits the release from the sediment, but also directly absorbs and removes phosphate from the water, which will effectively control the total phosphorus index.

[0038] IV. Enhancing Transparency The device generates micro- and nano-bubbles by controlling their size. These micro- and nano-bubbles are charged and have a high zeta potential, which can efficiently bind suspended solids, colloids, and planktonic organisms (algae, bacteria) in the water that affect transparency. These pollutants are then carried to the surface and removed by hydraulic machinery. Through this process, the highly efficient micro- and nano-bubble technology can effectively improve water transparency, making the water clearer.

[0039] It should be noted that the water areas requiring treatment include the restoration of static water bodies and their aquatic ecosystems, the remediation of polluted river water bodies, the protection of reservoirs and water sources, aquaculture, and the enhancement of the landscape of private garden fish ponds. The treatment involves multiple gases, including air, oxygen, ozone, carbon dioxide, and chlorine, and different gases have different effects. For example, ozone has strong oxidizing properties and can efficiently degrade organic matter, decolorize, disinfect, and reduce odors. This equipment is powered by mains electricity or clean energy. Example 2

[0040] Based on Embodiment 1, this utility model is as follows: Figures 1-6 As shown, the left and right ends of the front and rear sides of the shell cover 2 are fixedly connected with fixing sleeves 3. The inner side of the fixing sleeve 3 is provided with positioning lugs 301, and the inner side of the positioning lugs 301 is provided with connecting straps 302.

[0041] This technical solution: By setting the fixing sleeve 3 and the positioning lug 301, after fixing the connecting belt 302, and the lower end of the connecting belt 302 can extend to the bottom of the water, it can be fixed by various methods such as using a stone or fixing it to an anchor rod. After being fixed, the equipment can avoid moving around, and this method also facilitates the subsequent change of the equipment's usage location. Example 3

[0042] Based on Embodiment 1, this utility model is as follows: Figures 1-6 As shown, a limiting partition 601 is fixedly connected to one side of the positioning frame 6 and placed on the top of the pump body housing 4. A protective mesh cover 406 is provided at the liquid inlet of the turbine pump body 401, and a flange scraper 408 is provided on the outside of the protective mesh cover 406.

[0043] This technical solution: By setting up the protective mesh cover 406, the filtered water entering the bottom shell 1 can be further filtered, avoiding the adverse effects of larger particles on the operation of the turbine pump body 401. Moreover, after the external moving flange scraper 408 of the protective mesh cover 406, it is convenient to remove the filtered foreign objects outside the protective mesh cover 406, making it convenient for people to use.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
