Description

Technical Field

[0001] This invention relates to the field of liquid jet dispersion technology, and more specifically to an apparatus, method, and application capable of generating and spatially dispersing liquid balloons. Background Technology

[0002] The confined areas of reaction equipment (reactors) often require measures such as cooling, cleaning, and removal of reaction obstructions. A typical example is the CO2 methanation reactor that produces CH4 (methane) from CO2 and H2. This reactor typically uses a catalyst with Ni (nickel) as the main component, but due to the Sabatier reaction, abnormally high temperatures can easily occur in the main reaction zone. Because the area where high temperatures occur is relatively narrow, an effective local cooling method is needed, which involves supplying an appropriate amount of liquid to cool the local area. Traditional spray cooling methods are not suitable for this situation. If a large amount of cooling water is used, it may cause water accumulation inside the entire reactor, resulting in reactor failure or even inability to resume operation. Although cutting off the feed supply and stopping the entire reactor can effectively reduce the temperature, it will affect the reactor's operating efficiency. If a catalyst with poor reaction performance is used, although abnormally high temperatures can be avoided, it will lead to a decrease in the performance of the entire reactor system. In addition, for reactors where foreign matter is locally precipitated and causes flow obstruction, an appropriate liquid supply is also required to remove the foreign matter. Summary of the Invention

[0003] Objectives of the Invention: The first objective of this invention is to provide an apparatus capable of precisely supplying a small amount of liquid to a target area within a confined space, thereby achieving the generation and spatial dispersion of liquid balloons; the second objective of this invention is to provide a method capable of achieving the generation and spatial dispersion of liquid balloons; and the third objective of this invention is to provide the application of the apparatus capable of achieving the generation and spatial dispersion of liquid balloons in surface treatment.

[0004] Technical solution: The present invention provides a device capable of generating and spatially dispersing liquid balloons, comprising a gas-liquid mixing nozzle and a vibrator mounted on the gas-liquid mixing nozzle; the gas-liquid mixing nozzle has a gas-liquid mixing orifice, and the output end of the gas-liquid mixing orifice has an outlet orifice, the length of which is specified. Orifice diameter of the ejector hole satisfy The gas-liquid mixing nozzle is used to supply gas and non-viscous liquid, and mix them inside the gas-liquid mixing hole to form a two-phase flow suitable for generating liquid balloons. Liquid balloons are periodically and continuously generated at the nozzle. The liquid balloons are made of non-viscous liquid as the outer shell and filled with gas inside. The liquid film surface of the outer shell of the liquid balloon has slight disturbance or wrinkle deformation. The vibrator is used to apply low-frequency vibration to the gas-liquid mixing nozzle to disperse the liquid balloons into a predetermined space.

[0005] Furthermore, the liquid film forming the outer shell of the liquid balloon is tens to hundreds of micrometers thick and contains gas; the size of the liquid balloon ranges from several millimeters to 20 millimeters, and it is continuously generated at a rate of tens per second.

[0006] Furthermore, the gas-liquid mixing nozzle also includes a first gas supply flow path and a liquid supply flow path respectively connected to the gas-liquid mixing hole; the first gas supply flow path is used to supply gas, and the liquid supply flow path is used to supply non-viscous liquid; or, the first gas supply flow path is used to supply non-viscous liquid, and the liquid supply flow path is used to supply gas; a throttling section is provided in the first gas supply flow path to prevent backflow.

[0007] Furthermore, the vibrator is located on the outer side of the liquid supply flow path, the outer side of the first gas supply flow path, or the outer side of the gas-liquid mixing hole.

[0008] Furthermore, the vibrator is installed on the outer side of the gas-liquid mixing hole near the middle of the gas-liquid mixing hole.

[0009] Furthermore, the gas-liquid mixing nozzle is entirely encapsulated inside the housing, and the vibrator is located on the outer side of the housing, with the vibration generated by the vibrator transmitted through the housing.

[0010] Furthermore, the vibrator is fixed to the outer side of the housing with adhesive.

[0011] Furthermore, the vibrator includes a motor and an unbalanced rotor. The unbalanced rotor has a bias notch along the rotation direction. Low-frequency vibration is generated by the motor driving the unbalanced rotor to rotate. The vibration intensity is controlled by the oscillation controller by adjusting the voltage supplied to the motor.

[0012] The present invention provides a method for generating and spatially dispersing liquid balloons, employing the aforementioned apparatus for generating and spatially dispersing liquid balloons. The method for generating and spatially dispersing liquid balloons includes:

[0013] Gas and non-viscous liquid are continuously supplied to the gas-liquid mixing nozzle; after the gas-liquid mixing nozzle stably outputs liquid balloons, a vibration frequency not exceeding 200Hz is applied to the gas-liquid mixing nozzle, and the peak amplitude is controlled below 2mm, so that the liquid balloons are dispersed to a predetermined space; the diffusion range of the liquid balloons is controlled by the vibration intensity generated by the vibrator.

[0014] The present invention relates to the application of the device capable of generating and spatially dispersing liquid balloons, wherein the device is applied to surface treatment in a narrow space, the surface treatment including cooling and cleaning.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages:

[0016] This invention relates to a gas-liquid two-phase nozzle that continuously generates a balloon-shaped hollow liquid by spraying a mixture of liquid and gas, and further applies vibration to the gas-liquid two-phase nozzle to disperse the balloon-shaped hollow liquid into a predetermined area.

[0017] The morphology of liquid particles is crucial. Even if the liquid is supplied to the target area, if it fails to effectively contribute to the treatment process and instead experiences a "carry-over" phenomenon—that is, the liquid is carried away from the treatment area by surrounding airflow and ultimately becomes ineffective—the desired effect cannot be achieved. Generally, simple clusters of fine droplets are prone to this carry-over phenomenon. This invention generates liquid balloons that encapsulate gas within a spherical shell composed of a liquid film. By supplying these liquid balloons to a predetermined area, this invention can significantly reduce the required amount of water or medication for purposes such as cooling, cleaning, and obstacle removal through reaction. This is because the liquid balloons generated by this invention have a thicker liquid film and greater weight compared to soap bubbles, and their surface deforms while exhibiting stronger mechanical action upon rupture, thus producing a synergistic effect. Furthermore, this invention enables the liquid balloons to disperse laterally, thereby achieving a wider range of diffusion supply.

[0018] Furthermore, this invention features miniaturization and a simple structure, enabling the delivery of liquid balloons to localized areas within confined spaces, making it particularly suitable for surface treatment in narrow, horizontally extended two-dimensional planar spaces with low height. This invention allows for treatment during equipment operation without stopping or disassembling the device. This not only improves equipment operating efficiency but also significantly reduces maintenance costs. Moreover, it is of great safety significance, for example, in the event of reactor malfunctions, as it allows for rapid response measures. Attached Figure Description

[0032] The invention will now be further described with reference to the accompanying drawings.

[0035] In this embodiment, the liquid used is limited to a non-viscous liquid. Specifically, water, sulfuric acid, hydrochloric acid, and sodium hydroxide solution can be used, and the appropriate liquid can be selected according to the purpose of use. For example, when the purpose of use is cooling, a non-viscous liquid such as water can be used. When the purpose of use is to remove lipids, a non-viscous liquid such as sodium hydroxide solution can be used. Highly viscous liquids such as glycerol are not suitable for this invention.

[0036] The following describes an exemplary embodiment of the present invention using water as a non-viscous fluid.

[0037] Figure 1 This is a schematic diagram of a gas-liquid mixing nozzle structure according to a specific embodiment of the present invention. The internal structure of the gas-liquid mixing nozzle is shown in cross-section along the longitudinal axis.

[0038] Gas 2 is supplied from the upstream end of the first gas supply flow path 3, and flows into the gas-liquid mixing hole 5 after passing through the throttling section 4.

[0039] The function of the throttling section 4 is to prevent liquid backflow.

[0040] On the other hand, liquid 1 is supplied via liquid supply flow path 6, which is arranged parallel to the first gas supply flow path 3, and enters the gas-liquid mixing hole 5 through the confluence flow path 7 at the downstream position of the throttling section 4. As a result, liquid 1 and gas 2 mix in the gas-liquid mixing hole 5 to form a gas-liquid two-phase flow.

[0041] Furthermore, this embodiment is not limited to the above-described supply method; the supply locations for gas and liquid can also be interchanged.

[0042] In this embodiment, a vibrator 8 is installed on the side of the liquid supply flow path 6. The vibrator 8 includes a motor 9 and an unbalanced rotor 10. The motor 9 drives the unbalanced rotor 10 to rotate, thereby generating mechanical vibration. This vibration is transmitted to the entire gas-liquid mixing nozzle through the liquid supply flow path 6, causing the gas-liquid mixing nozzle to vibrate.

[0043] The vibration intensity is controlled by the oscillation controller 12 by adjusting the applied voltage.

[0044] When the applied voltage increases, the vibration amplitude and vibration frequency of the gas-liquid mixing hole 5 also increase.

[0045] exist Figure 1 middle, The cross-sectional view shows the configuration of the vibrator 8, the liquid supply path 6, and the first gas supply path 3.

[0046] in addition, The cross-sectional view shows the structure at the point where gas 2 and liquid 1 merge.

[0047] Gas-liquid mixing hole 5 As shown in the directional view, the tube has a circular opening when viewed from a horizontal cross-section.

[0048] Let the length of the gas-liquid mixing hole 5 be... The diameter of nozzle 13 is Then the length of the gas-liquid mixing hole With the diameter of the ejection hole The ratio should at least satisfy:

[0049]

[0050] The above proportional relationship is a necessary condition to be met in the design of gas-liquid mixing hole structure.

[0051] The above-mentioned dimensional conditions are the necessary structural conditions for realizing the core technology of this invention—the generation of liquid balloons, which can ensure that the required two-phase flow pattern of gas and liquid is formed inside the gas-liquid mixing hole.

[0052] The following provides further explanation of this embodiment:

[0053] like Figure 1 As shown, a vibrator 8 is installed on the liquid supply flow path 6.

[0054] As mentioned above, in the gas-liquid mixing nozzle of the present invention, the gas and liquid supply paths are not limited to the above embodiments, and the two can be interchanged.

[0055] Specifically, in Figure 1 In the illustrated embodiment, the liquid supply path 6 is not limited to conveying liquids, but can also be used as a gas supply path.

[0056] In addition, Figure 1 In this invention, the vibrator 8 is not limited to being installed on the liquid supply path 6, but can also be installed on the first gas supply path 3. The key to this invention is to cause the ejection orifice 13 to vibrate.

[0057] Under the condition of the above-mentioned ejection orifice length, an approximately uniformly distributed annular liquid film can be formed on the inner wall of the ejection orifice, and a liquid balloon can be stably generated.

[0058] The resulting liquid balloon can maintain a certain degree of stability and will not rupture immediately after formation.

[0059] Figure 2 As shown Figure 1 A variation of the illustrated embodiment. In this structure, the liquid supply path 6 and the gas-liquid mixing hole 5 connected via the confluence path 7 are housed inside the housing 14, and a vibrator 8 is disposed on the outer wall of the housing 14. The vibrator 8 is fixed to the housing 14 by an adhesive 15.

[0060] According to this structure, since the vibration generated by the vibrator 8 is transmitted through the housing 14, the vibration modes of the liquid supply path 6 and the gas-liquid mixing hole 5 are not easily separated from each other. In addition, since the overall structure is encapsulated inside the housing 14, it has the advantage of facilitating the smooth delivery of the nozzle body into the equipment being constructed.

[0061] Figure 3 The image shown is different from the one shown. Figure 1 Another embodiment of the illustrated example is shown. In this embodiment, the vibrator 8 is disposed on the outer side of the gas-liquid mixing hole 5. The advantage of this embodiment is that it can directly apply vibration to the flow path itself that supplies the gas-liquid mixture. The installation position of the vibrator 8 should not be too close to the ejection hole 13, and it is preferable to be disposed near the middle of the length L of the gas-liquid mixing hole 5.

[0062] Figure 4 The process of liquid balloon 17 being generated from nozzle 13 is shown, but under these conditions, no vibration is applied to the nozzle. After the annular liquid film flow 16 is ejected from nozzle 13, it expands under the action of internal airflow, thereby forming liquid balloon 17. This liquid balloon 17 is generated continuously in a periodic manner, with adjacent liquid balloons 17 initially connected by elongated liquid columns 18. Subsequently, the elongated liquid columns 18 break, forming liquid filaments 20 and droplets 19. It should be noted that in the actual generation process, not only liquid balloons 17 are formed, but also liquid particles such as droplets 19 may be generated and float between adjacent liquid balloons 17.

[0063] Figure 5The morphology of the liquid balloon 17 is illustrated by way of example. On the surface of the liquid balloon 17, a wrinkle-like surface deformation 21 can be observed. This surface deformation is formed by the superposition of disturbances on the surface of the annular liquid film inside the gas-liquid mixing hole 5 and disturbances caused by the velocity difference between the liquid balloon and the surrounding air after it is ejected from the ejection hole 13.

[0064] The liquid balloon 17 of this invention exhibits disturbances on both its inner and outer surfaces (interfaces), and this surface deformation 21 is the fundamental characteristic that distinguishes it from ordinary soap bubbles. It functions effectively when it comes into contact with or collides with a target object. During cooling, the surface deformation 21 increases the solid-liquid contact frequency. During cleaning, the surface deformation 21 can peel away dirt from solid surfaces. Furthermore, the liquid particle swarm generated when the liquid balloon 17 ruptures also possesses strong kinetic energy, a characteristic also derived from the surface deformation 21.

[0065] like Figure 6 The figure shows the phenomenon that occurs when the gas-liquid mixing hole 5 is vibrated using the method of the present invention under the conditions of liquid balloon generation.

[0066] The jet stream, composed of multiple liquid balloons 17, exhibits a distinct serpentine oscillation pattern, resembling a large-scale swinging motion. Simultaneously, the liquid balloons 17 separate to the left and right and gradually diffuse.

[0067] Near the ejection orifice 13, elongated liquid filaments 20 are generated between multiple liquid sacs 17. As the liquid flow moves downstream, the liquid filaments 20 gradually break and evolve into larger droplets 19.

[0068] In summary, by applying vibration to the gas-liquid mixing hole 5, the liquid balloon 17 can be diffused and distributed over a wide range to both sides of the jet. Furthermore, the vibration intensity generated by the vibrator 8 can control the range of diffusion of the liquid balloon to the left and right sides.

[0069] The vibration generated by the ejection orifice 13 is a low-frequency vibration, typically not exceeding 200Hz. While a larger vibration amplitude is beneficial for improving the diffusion effect of the liquid balloon, excessive amplitude can lead to a decrease in device durability. Therefore, in this invention, it is preferable to control the peak-to-peak amplitude to below 2mm.

[0070] Experiments show that within the above-mentioned vibration intensity range, the lateral diffusion control of the liquid balloon can be effectively achieved, thereby fully achieving the intended technical objective of this invention.

[0071] like Figure 7 As shown, the amount of liquid injected is required to achieve the same cooling effect under different cooling methods. A comparison was made, including: using traditional spray cooling methods, using liquid balloon impact methods, and such as Figure 6 This illustrates the method of applying vibration to the fluid-filled balloon array. The vertical axis shows the fluid volume used. Both are based on the liquid volume used in traditional spraying methods. Perform normalization processing, that is, use As a dimensionless evaluation parameter. Therefore, the situation corresponding to the traditional spraying method is as follows: When using a series of liquid balloons, This means that the required amount of coolant is reduced to about one-third of that of the traditional method. Therefore, this invention can effectively reduce the amount of coolant used.

[0072] Furthermore, in this invention, when the liquid balloon array is vibrated, the following is obtained: As a result, compared with existing technologies, the amount of liquid used can be reduced by less than 10%, demonstrating an extremely excellent liquid-saving effect.

[0073] Figure 8 This is a schematic diagram of the present invention applied to cleaning a honeycomb element 23, which is used to purify exhaust gas.

[0074] Vibration The liquid balloon 17 ejected from the ejection hole 13 of the gas-liquid mixing hole 5 under action forms a balloon jet 22 that sprays out to the left and right. In this balloon jet 22, the liquid balloon 17 is injected into the channel of the honeycomb element 23 from the honeycomb channel inlet 24.

[0075] The gas-liquid mixing orifice 5 is configured to move vertically or horizontally. This movement is referred to here as nozzle traverse. ).

[0076] In this manner, the liquid balloon 17 can be sprayed onto the entire area of ​​the cellular element 23.

[0077] Figure 9 Showing Figure 8 The phenomenon occurring inside the honeycomb channel after the liquid balloon 17 is injected. The liquid balloon 26 within the honeycomb channel flows along the inner surface of the honeycomb channel wall 25, and during the rupture of its liquid film 29, the attached material 28 disintegrates and is removed. The liquid film 29 of the liquid balloon remains attached to the inner surface of the honeycomb channel wall 25 and moves forward (as shown in the figure). (Indicates forward movement); at the same time, the subsequent liquid balloon 27 also moves forward in the same manner.

[0078] Through the above process, the deposits 28 that exist as pollutants in the honeycomb channel can be gradually cleaned and removed by the liquid balloons 26 in the honeycomb channel.

[0079] Figure 10 In this embodiment of the invention, due to the vibration of the gas-liquid mixing hole 5 in the left-right direction... The liquid balloons 17 disperse and fly to the left and right. The impact areas of each liquid balloon 17, that is, the cooling areas 30 formed by the balloon impact, have little overlap. Therefore, efficient cooling can be achieved with a smaller amount of cooling water.

[0080] Figure 11 The diagram illustrates a conventional water jet cooling method, in which cooling water jets 33 are ejected from nozzles 32 arranged on a cooling water main duct 31. These cooling water jets 33 diffuse in the downstream region and interfere with each other in the jet collision region 34. In this interference region 35, a large amount of cooling water that does not directly contribute to cooling remains, thus a significant amount of cooling water is wasted ineffectively.

[0081] Furthermore, the problems extend beyond resource waste. Large amounts of cooling water also increase the burden on subsequent water treatment facilities and require additional electricity and chemicals. Simultaneously, it can cause corrosion of surrounding equipment. This is especially true for equipment requiring high precision, such as… Figure 11 The traditional cooling methods shown are not applicable.

[0082] The following examples illustrate the basic structure, function, and effect of the liquid spherical generation and dispersion method proposed in this invention when applied to the cooling effect of an abnormally high temperature region generated by a plate catalyst during the conversion of CO2 into methane.

[0083] Figure 12 The following state is demonstrated: For the second gas supply path 37 of the plate catalyst 36, liquid balloon 17 is ejected from the ejector hole 13 at the outlet of the gas-liquid mixing hole 5 due to vibration. The liquid balloon 17 enters the supply area between the upper and lower plates in a left-right dispersion manner. The distance between the upper and lower plates is approximately... The gas-liquid mixing orifice 5 moves laterally in the left-right direction (Nozzle Traverse). Of course, this lateral movement can also be performed vertically or diagonally.

[0084] Figure 13 The following state was demonstrated: In a plate catalyst, the abnormally high temperature distribution (without intervention) 38, originally located near the gas inlet, was restored to a uniform temperature distribution 41 after applying the present invention. This is due to the effect of the cooling water bulb in the present invention being successfully supplied to the interior of the catalyst flow path. When the supply of cooling water bulb is stopped, the temperature rises again, thus causing the periodic nozzle traverse of the gas-liquid mixing orifice 5 to cause the temperature to rise again. Repeat the cooling process.
