[0001] The present invention belongs to the field of ship and ocean engineering, and particularly relates to a large-scale bubble group generation and regulation device and method. Background Art

[0002] Large-scale bubble groups play an important role in various fields and applications, including promoting the fusion of different components of liquids, suspending solid particles, clarification and separation, and cooling. In the field of ship and ocean engineering, large-scale bubble groups can absorb the energy of shock waves or cooperate with high-pressure bubbles for efficient damage. Therefore, large-scale bubble groups are of great significance in both industrial production and scientific research. Existing methods for generating large-scale bubble groups usually require certain equipment and operation techniques, specifically including injecting high-pressure gas into liquids, stirring air into liquids, using ultrasonic waves to generate bubbles, etc. Therefore, providing a simpler method for generating large-scale bubble groups helps to better understand the underwater movement and expansion mechanism of large-scale bubble groups to promote the development of industrial production and scientific research progress. Summary of the Invention

[0003] In view of this, the present invention aims to provide a large-scale bubble group generation and regulation device and method to solve the problem that it is difficult to control the gas generation rate and initial pressure during the generation process of large-scale bubble groups.

[0004] To achieve the above object, the present invention adopts the following technical solutions. According to one aspect of the present invention, a large-scale bubble group generation and regulation device is provided, including:

[0005] A pressure-resistant housing, with a water storage tank and a pressure vessel disposed inside. The bottom of the water storage tank and the pressure vessel are connected. The upper part of the water storage tank is connected to a pressure tank through a one-way inflation valve. The exhaust port provided on the top wall of the pressure vessel is communicated with the outside of the pressure-resistant housing;

[0006] A magnetic adsorption type charge net box, adsorbed on the top wall of the pressure vessel and closing the exhaust port, with a hydrogen-containing alkali metal compound disposed inside;

[0007] An adjustable card slot, disposed on the inner side wall of the pressure vessel, for clamping the magnetic adsorption type charge net box after it detaches from the top wall of the pressure vessel, so that the hydrogen-containing alkali metal compound in the magnetic adsorption type charge net box enters a certain depth underwater and contacts with water.

[0008] Furthermore, a water storage tank pressure gauge and a one-way exhaust valve are provided on the upper part of the water storage tank. A partition floating on the water surface and adapted to the inner wall of the water storage tank is disposed inside. An inlet is provided on the side wall of the water storage tank, between its bottom wall and the partition.

[0009] Furthermore, the water inlet of the pressure vessel of the water storage tank is connected to the water storage tank through a pipeline, and a water stop valve is provided at the connection of the water storage tank and the pipeline.

[0010] Furthermore, a pressure gauge for the pressure vessel is provided at the upper part of the pressure vessel.

[0011] Furthermore, a cooling component coupled to the pressure vessel is provided inside the pressure-resistant housing for cooling the pressure vessel.

[0012] Furthermore, the cooling component includes a water pump, a water circulation system inlet, a water circulation system outlet, and cooling water pipes. The water circulation system inlet and the water circulation system outlet are both provided on the wall of the pressure-resistant housing. The water circulation system inlet and the water circulation system outlet are connected by the cooling water pipes. The water pump is provided on the cooling water pipes. The cooling water pipes are coupled to the wall surface of the pressure vessel.

[0013] Furthermore, the magnetic adsorption type charge box includes a partition board, an automatic exhaust valve, a charge box, exhaust holes, and sleeves. An electromagnet is provided at the upper part of the magnetic adsorption type charge box, and a plurality of charge boxes are provided at the lower part. Exhaust holes are provided at the upper part of each charge box. A plurality of sleeves are provided on the partition board. Each charge box is inserted into a corresponding sleeve, and each charge box is communicated with the exhaust holes through the automatic exhaust valve provided in the corresponding sleeve. A certain height of hydrogen-containing alkali metal compound is provided in each charge box. A fixed card slot is provided on the inner wall of the pressure vessel below the adjustable card slot. The fixed card slot is used to limit the lowest position when the partition board slides on the charge box.

[0014] Furthermore, the charge box is a hollow column, and a cavity for accommodating the hydrogen-containing alkali metal compound is provided in the wall thickness. A slider is provided in the cavity, and a spring is provided between the slider and the top wall of the magnetic adsorption type charge box.

[0015] Furthermore, a filter screen is provided on one side wall of the charge box.

[0016] According to another aspect of the present invention, a method for using the above-mentioned large-scale bubble group generation and regulation device is provided, including the following steps:

[0017] S1. Calculate the exhaust volume per unit time of the exhaust port according to the required air pressure, convert the height of the adjustable card slot according to the exhaust volume to control the contact area between the hydrogen-containing alkali metal compound and water in the magnetic adsorption type charge box after it falls. Subsequently, fill the storage tank and the pressure vessel with gas at a specified pressure, and place the regulation device in water;

[0018] S2. Make the magnetic adsorption type charging net box lose magnetism and fall on the adjustable card slot. The hydrogen-containing alkali metal compound and water come into contact with a fixed contact area and start to generate gas. At the same time, the water pump works to drive the water circulation to cool the pressure vessel. Initially, the excessive gas in the pressure vessel is discharged, resulting in a decrease in the air pressure in the pressure vessel and an increase in the water level. The contact area between the water and the hydrogen-containing alkali metal compound increases, and an excessive amount of gas is rapidly generated to restore the air pressure in the pressure vessel to the equilibrium state. When the air pressure in the pressure vessel increases and the internal water level decreases, the pressure tank starts to work to increase the pressure in the water storage tank to increase the water level height in the pressure vessel. The pressure in the pressure vessel is restored, and the pressure tank stops working. When the air pressure in the pressure vessel decreases and the water level increases, the one-way exhaust valve opens at this time, the air pressure in the water storage tank decreases, the water level height in the pressure vessel is restored, and the one-way exhaust valve closes.

[0019] S3. As the control device continues to work, the total amount of hydrogen generated increases, and the generated hydrogen gas mass floats up to form a large-scale bubble group. When the hydrogen-containing alkali metal compound in the magnetic adsorption type charging net box is completely consumed, a fixed volume of hydrogen is generated, and the device stops working.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. By setting the magnetic adsorption type charging net box, this device can block the exhaust port set on the top wall of the pressure vessel under normal conditions to prevent the outside water from entering the device. At the same time, the magnetic adsorption type charging net box acts as the switch and raw material provider of the bubble group generating device, which can streamline the structure and ensure the smooth progress of the process of generating the bubble group.

[0022] 2. By setting the water storage tank and the pressure vessel, through a certain pre-charged gas pressure, it is ensured that the outside water will not enter the device during the falling process of the magnetic adsorption type charging net box. Therefore, it can avoid the influence of the outside water on the generation of the large-scale bubble group of this device to a certain extent. Filling hydrogen inside can increase the pressure in the cavity and prevent the generated high-temperature hydrogen from contacting the oxygen in the pressure vessel and causing an explosion.

[0023] 3. Through the cooperation of the magnetic adsorption type charging net box and the adjustable card slot, the height of the magnetic adsorption type charging net box immersed in water is controllable. By adjusting the liquid level height in the pressure vessel through the pressure difference between the pressure vessel and the water storage tank, the contact area between the hydrogen-containing alkali metal compound and water can be controlled, and then the hydrogen generation rate can be controlled to achieve the purpose of adjusting the generation rate of the bubble group.

[0024] 4. By setting a water pipe to cool the pressure vessel, it is prevented that the increase in temperature affects the hydrogen generation rate, thereby affecting the generation rate of the large-scale bubble group. Description of the Drawings

Detailed implementation manners

[0034] Referring to the accompanying drawings to illustrate this implementation manner, according to one aspect of the present invention, a large-scale bubble group generation and regulation device is provided, including:

[0035] The pressure-resistant housing 1 is internally provided with a water storage tank 2 and a pressure vessel 3. The bottom of the water storage tank 2 is communicated with the pressure vessel 3. The upper part of the water storage tank 2 is connected to a pressure tank 4 through a one-way inflation valve 5. The exhaust port 12 provided on the top wall of the pressure vessel 3 is communicated with the outside of the pressure-resistant housing 1. The pressure-resistant housing 1 is provided to prevent the underwater pressure from affecting the internal structure. For the pressure tank 4, hydrogen can be input into the water storage tank 2 through the one-way inflation valve 5, so as to adjust the partition plate 8 through the gas pressure and the one-way exhaust valve 7, and then drive the water inside through the partition plate 8, so as to control the liquid level height of the water in the pressure vessel 3 in real time according to the reaction process of the hydrogen-containing alkali metal compound 28 and stabilize the generation process of the large-scale bubble group. The exhaust port 12 is provided to discharge the final gas out of the device, so as to form a large-scale bubble group, and corresponding research work is carried out by shooting with a high-speed camera.

[0036] The magnetic adsorption type charge net box 14 is adsorbed on the top wall of the pressure vessel 3 and closes the exhaust port 12, and is internally provided with a hydrogen-containing alkali metal compound 28. When the magnetic adsorption type charge net box 14 does not break away from the exhaust port 12, it can act as a plug for the exhaust port 12 to prevent the external water from entering the device and contacting the hydrogen-containing alkali metal compound 28 in the magnetic adsorption type charge net box 14 in advance, which affects the generation of the bubble group. After the magnetic adsorption type charge net box 14 breaks away from the exhaust port 12, the generated gas can be smoothly discharged to form a large-scale bubble group.

[0037] The adjustable card slot 15 is arranged on the inner side wall of the pressure vessel 3 and is used to clamp the magnetic adsorption type charge net box 14 after the magnetic adsorption type charge net box 14 breaks away from the top wall of the pressure vessel 3, so that the hydrogen-containing alkali metal compound 28 in the magnetic adsorption type charge net box 14 enters a certain depth underwater and contacts the water. The adjustable card slot 15 is mainly to provide a support point when the magnetic adsorption type charge net box 14 falls. Specifically, some buckles can be arranged at intervals in the vertical direction on the inner wall of the pressure vessel 3, and some buckles that cooperate with the buckles can be arranged on the adjustable card slot 15 for connection. Here, the existing buckle structure can also be used, and any structure that can achieve quick disassembly and ensure the support strength of this application can be used in this application, and will not be elaborated here.

[0038] In this embodiment, a water storage tank pressure gauge 6 and a one-way exhaust valve 7 are arranged on the upper part of the water storage tank 2, and a partition plate 8 floating on the water surface and adapted to the inner wall of the water storage tank 2 is arranged inside the water storage tank 2. An inlet 9 is arranged on the side wall of the water storage tank 2 between its bottom wall and the partition plate 8.

[0039] In this embodiment, the water storage tank 2 is communicated with the pressure vessel water inlet 11 of the pressure vessel 3 through a pipeline, and a water stop valve 10 is arranged at the connection of the water storage tank 2 and the pipeline. The water stop valve 10 is provided to control whether the water in the water storage tank 2 enters the pressure vessel 3.

[0040] In this embodiment, a pressure gauge 13 for a pressure vessel is provided on the upper part of the pressure vessel 3. The pressure gauge 13 for the pressure vessel is provided to monitor the pressure inside the pressure vessel 3, so as to judge and adjust whether the corresponding pressure tank 4 replenishes the pressure in the water storage tank 2 according to the pressure value, or discharges the pressure through the one-way exhaust valve 7, so as to maintain the contact area between the hydrogen-containing alkali metal compound 28 and water in the magnetic adsorption charging net box 14 according to the corresponding adjustment. The hydrogen-containing alkali metal compound is a chemical substance that reacts with water to generate a large amount of gas.

[0041] In this embodiment, a cooling component coupled with the pressure vessel 3 is provided inside the pressure-resistant housing 1 for cooling the pressure vessel 3. The cooling component is provided to cool the pressure vessel 3 to prevent the high heat generated by the reaction of the hydrogen-containing alkali metal compound 28 with water from affecting the generation of large-scale bubble groups.

[0042] In this embodiment, the cooling component includes a water pump 18, a water circulation system water inlet 19, a water circulation system water outlet 20 and a cooling water pipe. The water circulation system water inlet 19 and the water circulation system water outlet 20 are both provided on the wall surface of the pressure-resistant housing 1. The water circulation system water inlet 19 and the water circulation system water outlet 20 are connected through the cooling water pipe. The water pump 18 is provided on the cooling water pipe. The cooling water pipe is coupled with the wall surface of the pressure vessel 3. The water pump 18 is also remotely controlled by an external controller. When the large-scale bubble group generating device starts to work, the water pump 18 is remotely controlled to operate. The water in the experimental environment will enter from the water circulation system water inlet 19 and flow in the cooling water pipe, take away the heat of the pressure vessel 3 and then discharge it from the water circulation system water outlet 20, so as to reduce the influence of the high heat of the pressure vessel 3 on the hydrogen generation rate and the like. The cooling water pipe is specifically in the form of a serpentine pipe and is wound around the outer wall of the pressure vessel 3. In this way, the contact area is increased to improve the heat dissipation effect.

[0043] In this embodiment, the magnetic adsorption type charge net box 14 includes a partition plate 16, an automatic exhaust valve 21, a net box 22, an exhaust hole 23, and a sleeve 24. An electromagnet is arranged on the upper part of the magnetic adsorption type charge net box 14, and a plurality of net boxes 22 are arranged on the lower part. An exhaust hole 23 is arranged on the upper part of each net box 22. A plurality of sleeves 24 are arranged on the partition plate 16. Each net box 22 is inserted into a corresponding sleeve 24, and each net box 22 is communicated with the exhaust hole 23 through the automatic exhaust valve 21 arranged in the corresponding sleeve 24. A certain height of hydrogen-containing alkali metal compound 28 is arranged in each net box 22. A fixed card slot 17 is arranged on the inner wall of the pressure vessel 3 below the adjustable card slot 15. The fixed card slot 17 is used to limit the lowest position of the partition plate 16 when sliding on the net box 22. The electromagnet can adsorb the pressure-resistant housing 1, and a corresponding material that can be adsorbed needs to be arranged on the inner wall of the pressure-resistant housing 1. The automatic exhaust valve 21 is arranged to discharge the hydrogen generated by the reaction of the hydrogen-containing alkali metal compound 28 in the net box 22 after contacting with water upward through the automatic exhaust valve 21, then enter the space above the partition plate 16 from the exhaust hole 23, and then be discharged from the exhaust port 12 to form a large-scale bubble group. The sliding part of the partition plate 16 and the net box 14 is coated with necessary water-based grease to ensure the smooth completion of the sliding process. The electromagnet can adopt the existing technology.

[0044] In this embodiment, the net box 22 is a hollow column, and a cavity for accommodating the hydrogen-containing alkali metal compound 28 is arranged in the wall thickness. A slider 27 is arranged in the cavity. A spring 26 is arranged between the slider 27 and the top wall of the magnetic adsorption type charge net box 14. The cross-sectional shape of the net box 22 is annular, and the cavity formed by the wall thickness is used to contain the hydrogen-containing alkali metal compound 28. In order to effectively contain the hydrogen-containing alkali metal compound 28, a filter screen 25 is only arranged on one side wall of the net box 22. In this way, the contact area is easy to calculate and the hydrogen generation rate is easy to control. The mesh size of the filter screen 25 needs to meet the requirement that water can enter but cannot overflow from the mesh holes.

[0045] According to another aspect of the present invention, a method for using the above-mentioned large-scale bubble group generation and regulation device is provided, including the following steps:

[0046] S1, calculate the exhaust volume per unit time of the exhaust port 12 according to the required air pressure, convert the height of the adjustable card slot 15 according to the exhaust volume to control the contact area between the hydrogen-containing alkali metal compound 28 and water in the magnetic adsorption type charge net box 14 after it falls, and then fill the storage tank 2 and the pressure vessel 3 with gas at a specified pressure, and place the regulation device in water;

[0047] S2. The magnetic - adsorption charging net box 14 loses its magnetism and falls onto the adjustable card slot 15, and the hydrogen - containing alkali metal compound 28 and water come into contact with a fixed contact area. The reaction of generating hydrogen in the pressure vessel 3 starts. At the same time, the water pump 18 works to drive the water circulation to cool the pressure vessel 3. Initially, the excessive gas in the pressure vessel 3 is discharged, resulting in a decrease in the air pressure and an increase in the water level in the pressure vessel 3. The contact area between water and the hydrogen - containing alkali metal compound 28 increases, and excessive gas is rapidly generated to restore the air pressure in the pressure vessel 3 to the equilibrium state. When the air pressure in the pressure vessel 3 increases and the internal water level decreases, the pressure tank 4 starts to work to increase the pressure in the water storage tank 2 to raise the water level in the pressure vessel 3. The pressure in the pressure vessel 3 is restored, and the pressure tank 4 stops working. When the air pressure in the pressure vessel 3 decreases and the water level increases, at this time, the one - way exhaust valve 7 opens, the air pressure in the water storage tank 2 decreases, the water level in the pressure vessel 3 is restored, and the one - way exhaust valve 7 closes.

[0048] S3. As the control device continues to work, the total amount of generated hydrogen increases, and the generated hydrogen gas mass floats upward to form a large - scale bubble group. When the hydrogen - containing alkali metal compound 28 in the magnetic - adsorption charging net box 14 is completely consumed, a fixed volume of hydrogen is generated, and the device stops working.

[0049] Initially, the water stop valve 10 is closed, and water is supplied to the water storage tank 2 through the water inlet 9. The pressure tank 4 pressurizes the water storage tank by inflating through the one-way inflation valve 5. The partition plate 8 floats on the water surface, separating the gas chamber and the liquid chamber. After the water stop valve 10 is opened by the control system, the water in the water storage tank enters the pressure vessel 3 through the pressure vessel water inlet 11. The water storage tank pressure gauge 6 detects the pressure in the water storage tank. When the pressure rises, the control system operates the one-way exhaust valve 7 to exhaust and reduce the pressure. When the pressure drops, the control system operates the pressure tank 4 to inflate the water storage tank through the one-way inflation valve 5 to regulate the pressure stability in the water storage tank. When the water stop valve 10 is opened, the control system controls the water circulation system to start cooling the pressure vessel 3. The water circulation system consists of a water pump 18, a water circulation system water inlet 19, and a water circulation system water outlet 20. Different components are connected by water pipes, and the water pipes are laid inside the wall of the pressure vessel 3. The flowing liquid absorbs the heat generated by the pressure vessel 3 to maintain a stable temperature inside the pressure vessel 3. The pressure vessel 3, the exhaust port 12, the pressure vessel pressure gauge 13, the magnetic adsorption type charge net box 14, the adjustable card slot 15, the partition plate 16, and the fixed card slot 17 form a bubble group generation system. Initially, hydrogen is initially filled in the pressure vessel 3 to prevent the generated high-temperature hydrogen from coming into contact with oxygen and causing an internal explosion. When water enters the pressure vessel 3, the control system operates the magnetic adsorption type charge net box 14 to lose magnetism and fall onto the adjustable card slot 15. The height of the adjustable card slot is regulated according to different pressure differences and the required gas generation rate. Water and the hydrogen-containing alkali metal compound 28 come into contact with a fixed contact area and generate a large amount of hydrogen. The upper exhaust port opens and starts exhausting. The pressure vessel pressure gauge 13 detects the pressure inside the pressure vessel in real time. The pressure difference between the pressure inside the pressure vessel 3 and the pressure inside the water storage tank 2 controls the water surface height inside the pressure vessel 3 to control the contact area between water and the hydrogen-containing alkali metal compound 28. The partition plate 16 floats on the water surface, and the partition plate 16 and the partition plate 8 press on the water surface to form pressure balance. When the difference between the water storage tank pressure gauge 6 and the pressure vessel pressure gauge 13 changes, the pressure tank 4 inflates the water storage tank or the one-way exhaust valve 7 to maintain relative pressure balance. When the bubble group generation rate increases, the air pressure inside the pressure vessel 3 increases, and the water surface inside the pressure vessel 3 drops. At this time, the one-way exhaust valve 7 opens, and the pressure inside the water storage tank drops. When the air pressure inside the pressure vessel 3 is too high, the partition plate 16 is stuck in the fixed card slot 17 to prevent the device from stopping working due to the drop of the water surface. When the bubble generation rate decreases, due to continuous exhaust, the air pressure inside the pressure vessel 3 drops, and the water surface rises, resulting in an increase in the contact area between water and the hydrogen-containing alkali metal compound 28. The pressure tank 4 inflates to increase the pressure inside the water storage tank 2 to regulate the bubble group generation rate.

[0050] The device is provided with a control module externally to control the corresponding components to act. The controllers, sensors and control programs that may be involved all adopt existing technologies and will not be elaborated here. For the convenience of observing the generation process of large-scale bubble groups, the necessary outer shell can be made of transparent material and used in conjunction with a high-speed camera, and can be arranged according to the actual situation.

[0051] The embodiments of the present invention disclosed above are only used to help explain the present invention. The embodiments do not describe all the details in detail, nor do they limit the invention to the specific embodiments described. According to the content of this specification, many modifications and changes can be made. These embodiments are selected and specifically described in this specification to better explain the principle and practical application of the present invention, so that those skilled in the art can understand and utilize the present invention well.

A method for using the large-scale bubble group generation and control device according to claim 4, characterized in that: The following steps are involved: S1, according to the required air pressure, the exhaust volume per unit time of the exhaust port (12) is calculated, and the height of the adjustable card slot (15) is converted according to the exhaust volume to control the contact area between the hydrogen-containing alkali metal compound (28) and water after the magnetic suction charging net box (14) falls, and then the water storage tank (2) and the pressure container (3) are filled with gas of a specified pressure, and the control device is placed in the water; S2, the magnetic charging net box (14) loses its magnetic force and falls on the adjustable slot (15), the hydrogen-containing alkali metal compound (28) and water contact with each other at a fixed contact area and begin to generate gas, while the water pump (18) works to drive the water circulation to cool the pressure vessel (3), initially the excessive gas in the pressure vessel (3) is discharged, resulting in a decrease in the air pressure in the pressure vessel (3) and an increase in the water level, the contact area between the water and the hydrogen-containing alkali metal compound increases, and excessive gas is rapidly generated to restore the air pressure in the pressure vessel (3) to a balanced state, when the air pressure in the pressure vessel (3) increases and the internal water level decreases, the pressure tank (4) starts to work to increase the pressure in the water storage tank (2) to increase the water level in the pressure vessel (3), the pressure in the pressure vessel (3) is restored, and the pressure tank (4) stops working, when the air pressure in the pressure vessel (3) decreases and the water level increases, the one-way exhaust valve (7) opens, the air pressure in the water storage tank (2) decreases, the water level in the pressure vessel (3) is restored, and the one-way exhaust valve (7) closes; S3, as the control device continues to work, the total amount of hydrogen generated increases, and the generated hydrogen gas mass floats up to form a large-scale bubble group. When the hydrogen alkali metal compound (28) in the magnetic charge box (14) is completely consumed and a fixed volume of hydrogen is generated, the device stops working.
