Description

Technical Field

[0001] The utility model relates to a device for preparing nano bubble water, belonging to the technical field of gas-water mixed dissolution treatment (B01F 1 / 00). Background Art

[0002] Currently, methods for producing nanobubble water are mainly divided into physical mixing and electrolysis. The physical mixing method mixes gas and water through different inlets and continuously circulates the gas-water mixture through a high-speed water pump. However, producing high-concentration nanobubble water requires an external power source, namely a high-speed water pump. The electrolysis method generates hydrogen and oxygen bubbles through electrolysis, which directly mix with the reacting water during the reaction. This has a limited volume and can easily affect the quality of the final nanobubble water. To maintain the quality of nanobubble water, the electrolysis water requires a power source, and the electrolyzed water must be separated from the raw water used to produce the nanobubble water. To increase the bubble concentration in the nanobubble water, the intensity or duration of the agitation in the water channel must be increased. In short, all existing methods for producing nanobubble water require a power source and its own electrical equipment, making it impossible to produce nanobubble water in environments where there is no power source or a lack of power. Utility Model Content

[0003] The technical problem to be solved by the utility model is how to prepare nano bubble water without relying on power supply and electric equipment.

[0004] The utility model proposes a technical solution to solve the above technical problems: a device for preparing nano bubble water, comprising a water tank, an ejector, a high-pressure gas source, a one-way valve, a Tesla valve and a nano bubble water tank, wherein the water inlet of the ejector is connected to the water outlet of the water tank, the air inlet of the ejector is connected to the air outlet of the high-pressure gas source via an air pipe, the air-water mixed outlet of the ejector is connected to the inlet of the Tesla valve via a one-way valve, and the outlet of the Tesla valve is connected to the inlet of the nano bubble water tank via a pipeline.

[0005] When the device for preparing nano bubble water of the utility model is used, the air outlet of the high-pressure gas source is opened, and the high-pressure gas quickly passes through the water inlet of the ejector from the air inlet of the ejector, bringing out the water in the water tank to form a gas-liquid mixture. The gas-liquid mixture enters the Tesla valve from the gas-water mixing outlet of the ejector through the one-way valve. The gas-water mixture is further mixed in the Tesla valve to generate a large number of nano bubbles, which eventually flow into the nano bubble water tank for storage.

[0006] The beneficial effects of the utility model are: 1) the water in the water tank is directly drawn out at high speed and mixed by high-pressure gas through the ejector, so no power supply and electric equipment are required; 2) the addition of a Tesla valve can enable the gas-water mixture mixed by the ejector to be further hammered and mixed by the water hammer effect in the Tesla valve, thereby generating a large number of nanobubbles, and finally obtaining the desired water containing a large number of nanobubbles and storing it.

[0007] Furthermore, the main water channel and the branch water channel of the Tesla valve have an angle of ≤90 degrees at the intersection.

[0008] Furthermore, the nano bubble water tank is configured as a pressure-resistant closed water tank, and an air outlet pressure relief hole and a pressure relief valve are provided on the nano bubble water tank.

[0009] Furthermore, the Tesla valve includes an inlet, an outlet and at least one diversion point.

[0010] Furthermore, the water tank is provided with an air inlet valve, the pressure in the nano bubble water tank is constant at 0.25 MPa, and the angle is 75 degrees to 85 degrees. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Example

[0016] A device for preparing nano bubble water in this embodiment, such as Figure 1 As shown, it includes a water tank 1, an ejector 2, a high-pressure gas source 3, a one-way valve 4, a Tesla valve 5 and a nano bubble water tank 6. The water inlet B of the ejector 2 is connected to the water outlet of the water tank 1, the air inlet A of the ejector 2 is connected to the air outlet of the high-pressure gas source 3 through an air pipe, the air-water mixed outlet C of the ejector 2 is connected to the inlet D of the Tesla valve 5 through the one-way valve 4, and the outlet E of the Tesla valve 5 is connected to the inlet F of the nano bubble water tank 6 through a pipeline.

[0017] like Figure 1 As shown, the water tank 1 of this embodiment is provided with an air inlet valve 7. When the water tank 1 is in a stationary state, the air inlet valve 7 is in a closed state. At this time, the interior of the water tank 1 is subjected to a uniform atmospheric pressure. Under the combined influence of gravity, liquid surface tension and atmospheric pressure, the water in the water tank 1 forms a stable convex liquid surface, preventing water from flowing out from the water inlet B of the ejector 2.

[0018] The high-pressure gas source 3 of this embodiment can be a high-pressure hydrogen tank, a high-pressure electrolyzer, or other gas tanks filled with high-pressure gas.

[0019] Ejector 2 Figure 2 As shown, high-pressure gas enters ejector 2 at its air inlet, end A, and rapidly passes through the area from end A to ejector 2's air-water mixing outlet, end C. Because the diameter of the ejector 2 gradually decreases from end A to end B, the gas flow velocity from end A to end B is increased. As the high-speed gas passes through the convex liquid surface at end B, it entrains water flowing out of the water tank. After mixing with the water, the high-speed gas rapidly exits from end C. Simultaneously with air intake at end A, opening the water tank's air inlet valve 7 allows air to enter the water tank 1.

[0020] Tesla Valve 5 Figure 3 As shown, the Tesla valve 5 of this embodiment includes an inlet D, an outlet E and three diversion points, but there should be at least one diversion point. After entering from the inlet D of the Tesla valve 5, it is divided into a main waterway 8 and a branch waterway 9. Due to the difference in water flow direction, the intersection and impact point K of the main waterway 8 and the branch waterway 9 produces a water hammer effect at point K, causing the water flow speed to slow down or stagnate at this point. Unlike the traditional Tesla pipe valve, the Tesla valve 5 used in this embodiment has been redesigned. The angle between the intersection and impact point K of the main waterway 8 and the branch waterway 9 after passing through different flow channels is ≤90 degrees. The angle is generally 75°-85°. This can increase the mixing effect of gas and liquid and increase the number of nanobubbles in the water. Finally, the high-speed gas-water mixture generates a large number of nanobubbles in the Tesla valve 5 to form nanobubble water, which flows out from the outlet E end of the Tesla valve 5 and is stored in the nanobubble water tank.

[0021] There are no absolute design parameters for the length and inner diameter of the improved Tesla valve 5 in this embodiment. These parameters need to be considered in their design, including flow rate, pressure, mixing efficiency, and the desired output. Calculations indicate that a longer length results in a more uniform mixing of the air-water mixture, a lower nanobubble water flow rate, and a higher bubble concentration in the resulting nanobubble water. A longer inner diameter also results in a greater output of the resulting nanobubble water. For example, for rural irrigation using nanobubble water, a Tesla valve with a length of 100 cm and an inner diameter of 4 cm can be used.

[0022] The nano bubble water tank 6 of this embodiment can be configured as a pressure-resistant closed water tank, thereby effectively preserving the formed nano bubble water. Figure 1As shown, the nanobubble water tank 6 receives water through the water inlet F (connected to the outlet E of the Tesla valve 5). A pressure relief hole G is provided on the nanobubble water tank 6, which is equipped with a pressure relief valve 10. The pressure relief valve 10 is set to a set value (e.g., 0.25 MPa) to maintain a stable pressure within the nanobubble water tank 6. As high-speed nanobubble water enters the sealed nanobubble water tank 6, the pressure within the tank 6 increases until it reaches the set pressure of the pressure relief valve 10. At this point, the air in the nanobubble water tank 6 is discharged through the pressure relief valve 10, ensuring that the pressure within the nanobubble water tank 6 remains constant at the set value of 0.25 MPa.

[0023] According to experiments, when the pressure is ≥ 0.25 MPa, the nanobubble water in the nanobubble water tank 6 of this embodiment can ensure the stable storage of nanobubbles for a long time, and the stable storage time can generally be up to 3 years or more.

[0024] When the device for preparing nanobubble water in this embodiment is used, the air outlet of the high-pressure gas source 3 is opened. When the high-pressure gas quickly passes through the water inlet B of the ejector 2 from the air inlet A of the ejector 2, the water in the water tank 1 is brought out to form a gas-liquid mixture. The gas-liquid mixture enters the Tesla valve 5 from the gas-water mixing outlet C of the ejector 2 through the one-way valve 4. The gas-water mixture is further mixed in the Tesla valve 5 to produce a large number of nanobubbles, which eventually flow into the nanobubble water tank 6 for storage.

[0025] The present invention is not limited to the above embodiments, and any technical solutions formed by equivalent replacements fall within the protection scope required by the present invention.
