Description

Technical Field

[0001] This utility model relates to the field of water environment management technology, and in particular to a deep well ultra-nano dissolved oxygenation system. Background Technology

[0002] Oxygen deficiency in shallow rivers and lakes has several negative consequences. First, it impacts the survival and reproduction of aquatic life, leading to mass mortality of fish, plankton, and other organisms, severely affecting the sustainable development of fishery resources. Second, it disrupts the balance of aquatic ecosystems, exacerbating eutrophication. Third, it affects reservoir water quality; oxygen deficiency leads to water quality deterioration, negatively impacting drinking water safety in surrounding areas. If water environment remediation is not implemented promptly, the continuous decomposition of organic matter in the bottom sediment will increase dissolved oxygen consumption, eventually leading to the depletion of dissolved oxygen at the bottom of rivers, lakes, and reservoirs, resulting in a putrid odor.

[0003] To address the oxygen deficiency problem in rivers and lakes, it is necessary to reoxygenate the lakes. However, conventional reoxygenation devices consume a lot of energy and have low oxygen utilization rates.

[0004] In view of this, it is necessary to design a deep-well ultra-nano dissolved oxygenation system to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a deep well ultra-nano dissolved oxygen reoxygenation system that can increase dissolved oxygen in water while reducing energy consumption and increasing oxygen utilization.

[0006] To achieve the above objectives, this utility model provides a deep well ultra-nano dissolved oxygen reoxygenation system, comprising a cryogenic storage tank for storing liquid oxygen, a vaporizer connected to the cryogenic storage tank, an ultra-nano dissolved oxygen reoxygenation device located at the bottom of the deep well, an outlet pump located within the deep well, a filtration system located within a natural water body, and an inlet pipe connecting the filtration system and the ultra-nano dissolved oxygen reoxygenation device; the outlet pump has an outlet pipe extending into the natural water body at its output end; the output end of the vaporizer is connected to the ultra-nano dissolved oxygen reoxygenation device; the natural water body, after being filtered by the filtration system, flows into the ultra-nano dissolved oxygen reoxygenation device through the inlet pipe, mixes with the oxygen vaporized by the vaporizer to form oxygen-enriched water, and the oxygen-enriched water flows out through the dissolved oxygen outlet of the ultra-nano dissolved oxygen reoxygenation device and is then pumped by the outlet pump to anoxic points in the natural water body.

[0007] As a further improvement of this utility model, the distance between the pumping port of the water outlet pipe and the bottom of the natural water body is 80cm-100cm.

[0008] As a further improvement of this utility model, the height difference between the horizontal plane where the water level line of the natural water body is located and the horizontal plane where the water inlet of the inlet pipe is located is greater than 120cm.

[0009] As a further improvement of this utility model, the diameter of the deep well is 60-80cm and the height is 50-70m.

[0010] As a further improvement of this utility model, the top of the ultra-nano aerosol reoxygenation device is provided with an opening that communicates with the outlet of the water inlet pipe.

[0011] As a further improvement of this utility model, the lower part of the ultra-nano aerosol reoxygenation device is provided with a plurality of aerosol outlets.

[0012] The beneficial effects of this utility model are:

[0013] This utility model provides a deep-well ultra-nano dissolved oxygen reoxygenation system, comprising a cryogenic storage tank for storing liquid oxygen, a vaporizer connected to the cryogenic storage tank, an ultra-nano dissolved oxygen reoxygenation device located at the bottom of the deep well, an outlet pump located within the deep well, a filtration system located within the natural water body, and an inlet pipe connecting the filtration system and the ultra-nano dissolved oxygen reoxygenation device. By placing the ultra-nano dissolved oxygen reoxygenation device at the bottom of the deep well, the natural pressure at the bottom of the deep well is used to achieve a water pressure of 0.6-0.8 MPa within the device. Under this pressure, oxygen vaporized by the vaporizer enters the ultra-nano dissolved oxygen reoxygenation device and dissolves into the water body to form oxygen-enriched water. The generated oxygen-enriched water flows upward through the deep well and is pumped by the outlet pump to multiple oxygen-deficient points in the natural water body. This design improves oxygen utilization and reduces pressurization energy consumption under the same operating pressure, saving more than 60% of electrical energy under the same operating pressure.

[0019] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0020] like Figure 1 As shown, this utility model provides a deep well ultra-nano dissolved oxygenation system, including a cryogenic storage tank 4 for storing liquid oxygen, a vaporizer 3 connected to the cryogenic storage tank 4, an ultra-nano dissolved oxygenation device 6 installed at the bottom of a deep well 5, an outlet pump 1 installed in the deep well 5, a filtration system 12 installed in a natural water body 9, and an inlet pipe 2 connecting the filtration system 12 and the ultra-nano dissolved oxygenation device 6. The outlet pump 1 has an outlet pipe extending into the natural water body at its output end. The output end of the vaporizer 3 is connected to the ultra-nano dissolved oxygenation device 6. After being filtered by the filtration system 12, the natural water flows into the ultra-nano dissolved oxygenation device 6 through the inlet pipe, where it mixes with the oxygen vaporized by the vaporizer 3 to form oxygen-enriched water. The oxygen-enriched water flows out through the dissolved oxygen outlet 7 of the ultra-nano dissolved oxygenation device 6 and is then pumped by the outlet pump 1 to the oxygen-deficient points in the natural water body 9. Several dissolved oxygen outlets 7 are located at the lower part of the ultra-nano dissolved oxygenation device 6.

[0021] Specifically, the distance between the pump outlet 10 of the water outlet pipe and the bottom of the natural water body 9 is 80cm-100cm.

[0022] The inlet 8 of the water inlet pipe 2 is connected to the filtration system 12, and the outlet of the water inlet pipe 2 is connected to the ultra-nano dissolved oxygenation device 6. Correspondingly, the top of the ultra-nano dissolved oxygenation device 6 is provided with an opening that connects to the outlet of the water inlet pipe.

[0023] The height difference between the water level 11 of the natural water body 9 and the water inlet 8 of the inlet pipe is greater than 120cm.

[0024] Deep well 5 has a diameter of 60-80cm and a height of 50-70m. The bottom of deep well 5 is under natural pressure.

[0025] The working principle of the deep-well ultra-nano aerosol reoxygenation system provided by this utility model is explained in detail below:

[0026] Liquid oxygen stored in cryogenic storage tank 4 is vaporized by vaporizer 3 to form oxygen at a certain pressure, which is regulated by vaporizer 3 to be 0.7-0.9 MPa. Natural water body 9 is filtered by filtration system 12 and flows into ultra-nano dissolved oxygenation device 6 through inlet pipe 2. Due to the natural pressure at the bottom of deep well 5, the water pressure in ultra-nano dissolved oxygenation device 6 can reach 0.6-0.8 MPa. Under this pressure, the oxygen vaporized by vaporizer 3 enters ultra-nano dissolved oxygenation device 6 and dissolves into the water to form oxygen-enriched water. The generated oxygen-enriched water is discharged through dissolved oxygen outlet 7, flows to the upper part of deep well, and is pumped to multiple oxygen-deficient points in natural water body 9 by outlet pump 1.

[0027] With this setup, the system improves oxygen utilization and reduces pressurization energy consumption under the same working pressure by utilizing the natural pressure at the bottom of the deep well 5, saving more than 60% of electrical energy under the same working pressure.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. 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 spirit and scope of the technical solutions of this utility model.
