Description

Technical Field

[0001] This invention relates to the field of gas-liquid reaction equipment technology, and particularly to a self-powered piezoelectric ceramic atomizing device. Background Technology

[0002] In gas-liquid reactions or hydrate formation processes, enhancing mass transfer between the gas and liquid phases and increasing the effective gas-liquid contact area are crucial for the rapid and efficient dissolution or intercalation of gases into the liquid phase, enabling the formation of valuable chemicals through reaction. However, the intrinsic solubility of gases in liquids is typically low, and their mass transfer processes are mainly limited by the narrow gas-liquid interface, resulting in slow dissolution or hydrate formation rates and lengthy reaction times under natural conditions. This bottleneck severely restricts the efficiency of laboratory research and the industrialization and application of related processes.

[0003] Currently, traditional technologies for promoting gas-liquid mass transfer and reaction mainly employ mechanical stirring, bubbling, and atomization. While these methods can increase the contact area to some extent, they are highly dependent on continuous external energy input, resulting in high system energy consumption. Furthermore, the complex mechanical structures lead to inconvenient maintenance and increased costs. More importantly, these systems generally lack energy self-adaptation capabilities, failing to effectively utilize low-grade energy widely available within or around the reaction system, such as temperature differences caused by exothermic reactions, vibrations during device operation, or fluctuations in the liquid itself, resulting in energy waste. Traditional fixed-installation stirrers, bubblers, or atomizers struggle to adapt to dynamic changes in the liquid level during the reaction (caused by evaporation, sampling, temperature changes, or water consumption due to hydrate formation). Once the liquid level drops, exposing fixed components to the gas phase, their function immediately fails, and they may even be damaged by dry burning. This is particularly detrimental to hydrate reactions or continuous gas-liquid reaction processes requiring long-term stable operation. Therefore, there is an urgent need for a simple floating structure that can adapt to liquid level fluctuations and maintain an optimal operating position to provide a stable and large gas-liquid contact area. Meanwhile, the structure should ideally be able to achieve energy self-sufficiency or low-power operation, utilizing free energy in the environment (such as fluctuation energy, temperature difference, etc.), thus forming a new type of gas-liquid mass transfer and hydrate generation enhancement device with simple structure, stable operation, and low maintenance cost. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a self-powered piezoelectric ceramic atomizing device, which aims to solve the problems of complex operation and low efficiency in the existing gas-liquid mass transfer and hydrate generation processes.

[0005] The technical solution of the present invention is as follows:

[0006] A self-powered piezoelectric ceramic atomizing device includes: a reaction vessel and a self-powered piezoelectric ceramic atomizer disposed within the reaction vessel; when liquid is present in the reaction vessel, the self-powered piezoelectric ceramic atomizer is in a floating state in the liquid;

[0007] The self-powered piezoelectric ceramic atomizer includes: a housing, a piezoelectric atomization module disposed within the housing, and a wave power generation module for supplying power to the piezoelectric atomization module;

[0008] The housing has a liquid inlet and a liquid outlet;

[0009] The piezoelectric atomization module includes: a liquid storage tank connected to the liquid inlet and the liquid outlet, a liquid inlet pipe for connecting the liquid storage tank to the liquid inlet, and a piezoelectric ceramic atomizing plate disposed at the liquid outlet.

[0010] The wave power generation module includes: a wave pressure sensor fixed inside the housing, a cantilever tube disposed on the wave pressure sensor, and a small metal ball disposed inside the cantilever tube.

[0011] The self-powered piezoelectric ceramic atomizing device, wherein the piezoelectric ceramic atomizing plate is composed of a metal sheet with micropores and a piezoelectric ceramic ring adhered to the metal sheet. Optionally, the metal sheet is embedded in the side wall of the housing, and the piezoelectric ceramic ring is disposed inside the housing.

[0012] The self-powered piezoelectric ceramic atomizing device further includes a converter disposed within the housing; the converter is used to convert the electrical signal generated by the wave power generation module into an electrical signal adapted to the piezoelectric atomizing module.

[0013] The self-powered piezoelectric ceramic atomizing device further includes: a base plate fixed inside the housing and a sensor base disposed on the base plate; the fluctuating pressure sensor is disposed on the sensor base.

[0014] The self-powered piezoelectric ceramic atomizing device includes a slot on the inner wall of the reaction vessel for mounting the self-powered piezoelectric ceramic atomizer; the self-powered piezoelectric ceramic atomizer can move freely in the vertical direction within the slot as the liquid level in the reaction vessel changes.

[0015] The self-powered piezoelectric ceramic atomizing device further includes a float for keeping the self-powered piezoelectric ceramic atomizer floating in the liquid.

[0016] The self-powered piezoelectric ceramic atomizing device further includes a temperature sensor for monitoring the temperature inside the reactor.

[0017] The self-powered piezoelectric ceramic atomizing device further includes a pressure sensor for monitoring the pressure inside the reactor.

[0018] The self-powered piezoelectric ceramic atomizing device further includes a magnetic stirring rotor disposed inside the reaction vessel for stirring the liquid.

[0019] Beneficial Effects: This invention proposes a self-powered piezoelectric ceramic atomizing device. This device consists of a self-powered piezoelectric ceramic atomizer installed inside a reactor, its core being a wave power generation module and a piezoelectric atomizing module. The wave power generation module directly converts the mechanical energy generated by the liquid fluctuations within the reactor into electrical energy, which drives the piezoelectric atomizing module. This self-powered piezoelectric ceramic atomizing device achieves self-sufficiency and high energy efficiency. The system operates independently of the external power grid, achieving "zero-carbon" energy supply by recovering mechanical energy from the reactor, reducing operating energy consumption and costs, and realizing green, low-carbon operation. Simultaneously, it improves gas dissolution efficiency, atomizing the liquid into micron-sized droplets, increasing the contact area between the gas and liquid phases, allowing the gas to be rapidly captured and dissolved by the droplets, thereby accelerating the mass transfer and dissolution rate and shortening the reaction or cultivation time. Furthermore, under the balance of gravity and buoyancy, the self-powered piezoelectric ceramic atomizer is in a floating state in the liquid of the reactor, ensuring that the self-powered piezoelectric ceramic atomizer is always in the optimal working position regardless of changes in the liquid level. This effectively avoids the "dry burning" damage and functional failure caused by the drop in liquid level of fixed devices, and ensures the continuity and reliability of long-term experiments or operation.

[0025] This invention provides a self-powered piezoelectric ceramic atomizing device. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention is further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0026] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0027] like Figures 1 to 4 As shown, this embodiment of the invention provides a self-powered piezoelectric ceramic atomizing device, including: a reaction vessel 1 and a self-powered piezoelectric ceramic atomizer 2 disposed in the reaction vessel 1; when there is liquid in the reaction vessel 1, the self-powered piezoelectric ceramic atomizer 2 is in a floating state in the liquid;

[0028] The self-powered piezoelectric ceramic atomizer 2 includes: a housing 21, a piezoelectric atomization module 22 disposed within the housing 21, and a wave power generation module 23 for supplying power to the piezoelectric atomization module 22;

[0029] The housing 21 has a liquid inlet 211 and a liquid outlet (not marked).

[0030] The piezoelectric atomizing module 22 includes: a liquid storage tank 221 connected to the liquid inlet 211 and the liquid outlet, a liquid inlet pipe 222 for connecting the liquid storage tank 221 to the liquid inlet 211, and a piezoelectric ceramic atomizing plate 223 disposed at the liquid outlet.

[0031] The wave power generation module 23 includes: a wave pressure sensor 231 fixed inside the housing 21, a cantilever tube 232 disposed on the wave pressure sensor 231, and a metal ball 2321 disposed inside the cantilever tube 232.

[0032] In this embodiment, a self-powered piezoelectric ceramic atomizer 2 is installed inside the reaction vessel 1 to accelerate the mass transfer and dissolution rate and shorten the reaction or culture time.

[0033] The self-powered piezoelectric ceramic atomizer 2 includes: a wave power generation module 23 and a piezoelectric atomization module 22.

[0034] The wave power generation module 23 includes: a wave pressure sensor 231, a cantilever tube 232 disposed on the wave pressure sensor 231, and a metal ball 2321 disposed inside the cantilever tube 232. When liquid waves generated in the reactor 1 due to stirring or natural convection impact the self-powered piezoelectric ceramic atomizer 2, the kinetic energy of the liquid drives the metal ball 2321 inside the cantilever tube 232 to oscillate back and forth, transmitting pressure to the wave pressure sensor 231 to generate mechanical energy, thereby triggering the formation of electrical energy. Specifically, the wave pressure sensor 231 contains a piezoelectric material. Under external pressure, the uneven charge distribution inside the piezoelectric material generates a potential difference, thereby converting mechanical energy into electrical energy.

[0035] The piezoelectric atomization module 22 includes a liquid storage tank 221 communicating with the liquid inlet 211 and liquid outlet of the housing 21, and a piezoelectric ceramic atomizing plate 223 disposed at the liquid outlet. Liquid in the reactor 1 enters the liquid storage tank 221 through the liquid inlet 211, and then returns to the reactor 1 from the liquid outlet facing inwards. Specifically, the piezoelectric ceramic atomizing plate 223, disposed at the liquid outlet, generates high-frequency axial vibration when it receives electrical energy from the wave power generation module 23. This vibration tears the liquid in the liquid storage tank 221 into micron-sized droplets, forming a dense mist-like area, thereby greatly increasing the surface area of ​​the gas-liquid two-phase contact.

[0036] Furthermore, after the liquid storage tank 221 is connected to the liquid inlet 211 and the liquid outlet of the shell 21, a hollow closed space is formed between the liquid storage tank 221 and the shell 21, similar to a float in an oil drum. Under the balance of gravity and buoyancy, the self-powered piezoelectric ceramic atomizer 2 is in a floating state in the liquid in the reaction vessel 1, and floats up and down with the change of the liquid level in the reaction vessel 1, ensuring that it is always in contact with the water surface and maintains the optimal working position. This effectively avoids the damage and functional failure of the fixed device due to the drop of the liquid level, and ensures the continuity and reliability of long-term experiments or operation.

[0037] In some embodiments, the piezoelectric ceramic atomizing sheet 223 consists of a metal sheet 2231 with micropores and a piezoelectric ceramic ring (not shown) adhered to the metal sheet 2231.

[0038] In some more specific embodiments, the metal sheet 2231 is embedded in the side wall of the housing 21, and the piezoelectric ceramic ring (not shown) is disposed inside the housing 21. Specifically, when electrical energy is obtained, the piezoelectric ceramic ring generates high-frequency axial vibration, driving the liquid in the liquid storage tank 221 through the micropores of the metal sheet 2231, thereby tearing the liquid into micron-sized droplets and forming a dense mist-like area.

[0039] In some implementations, such as Figure 2 and Figure 3 As shown, the self-powered piezoelectric ceramic atomizer 2 further includes a converter 24 disposed within the housing; the converter 24 is used to convert the electrical signal generated by the wave power generation module 23 into an electrical signal compatible with the piezoelectric atomization module 22. Specifically, in this embodiment, the piezoelectric atomization module 22 can be a conventional commercially available product, and the converter 24 can convert the voltage generated by the wave power generation module 23 into a voltage compatible with the piezoelectric atomization module 22, thereby enabling the wave power generation module 23 to supply power to the piezoelectric atomization module 22.

[0040] In some implementations, such as Figure 2 and Figure 3 As shown, the self-powered piezoelectric ceramic atomizer 2 further includes: a base plate 25 fixed inside the housing 21 and a sensor base 26 disposed on the base plate 25; the fluctuating pressure sensor 231 is disposed on the sensor base 26.

[0041] In some implementations, such as Figure 2 and Figure 3 As shown, the self-powered piezoelectric ceramic atomizer 2 further includes a wire 27 for connecting the wave power generation module 23 and the piezoelectric atomization module 22. Specifically, the wire 27 can be partially hidden in the base plate 25.

[0042] In some implementations, such as Figure 1 As shown, the inner wall of the reactor 1 is provided with a slot 11 for mounting the self-powered piezoelectric ceramic atomizer 2; the self-powered piezoelectric ceramic atomizer 2 can move freely in the vertical direction within the slot 11 as the liquid level in the reactor 1 changes. Specifically, the self-powered piezoelectric ceramic atomizer 2 is disposed within the slot 11 and spaced apart from the inner wall of the slot 11. The opening of the slot 11 is smaller than the size of the self-powered piezoelectric ceramic atomizer 2, thereby allowing the self-powered piezoelectric ceramic atomizer 2 to move freely in the vertical direction within the slot 11 as the liquid level in the reactor 1 changes.

[0043] In some embodiments, the self-powered piezoelectric ceramic atomizing device further includes a float (not shown) for keeping the self-powered piezoelectric ceramic atomizer floating in the liquid. Specifically, the float is a lightweight material (such as foam) with a density lower than that of the liquid, used to balance gravity and buoyancy to achieve floating, ensuring that the liquid inlet of the self-powered piezoelectric ceramic atomizer is always in contact with the liquid surface, thereby enabling stable atomization.

[0044] In some implementations, such as Figure 1 As shown, the self-powered piezoelectric ceramic atomizing device further includes a temperature sensor 3 for monitoring the temperature inside the reaction vessel 1. Specifically, real-time monitoring of the temperature conditions inside the reaction vessel 1 ensures that the reaction proceeds under optimal conditions.

[0045] In some implementations, such as Figure 1 As shown, the self-powered piezoelectric ceramic atomizing device further includes a pressure sensor 4 for monitoring the pressure inside the reaction vessel 1. Specifically, real-time monitoring of the pressure conditions inside the reaction vessel 1 ensures that the reaction proceeds under optimal conditions.

[0046] In some implementations, such as Figure 1 As shown, the self-powered piezoelectric ceramic atomizing device further includes a magnetic stirring rotor 5 disposed within the reaction vessel 1 for stirring the liquid. Specifically, the magnetic stirring rotor 5 rotates within the reaction vessel 1 under the drive of an external magnetic field, thereby stirring the liquid to achieve circulation, promote full contact between gas and liquid, and simultaneously provide the necessary kinetic energy for the self-powered piezoelectric ceramic atomizer 2.

[0047] In one specific embodiment, the operation process of the self-powered piezoelectric ceramic atomizing device is as follows:

[0048] The self-powered piezoelectric ceramic atomizer 2 is installed in the slot 11 of the reaction vessel 1. After adding the gas, liquid and magnetic stirring rotor 5 to be reacted, the reaction vessel 1 is sealed. Under the balance of gravity and buoyancy, the self-powered piezoelectric ceramic atomizer 2 automatically adjusts its position and floats in the liquid in the reaction vessel 1.

[0049] An external magnetic field is applied to drive the magnetic stirring rotor 5 to rotate, generating liquid waves, which in turn drive the wave power generation module 23 to generate electricity. The electrical energy is then regulated by the converter 24 and transmitted to the piezoelectric atomization module 22.

[0050] After receiving electrical energy, the piezoelectric atomization module 22 generates high-frequency vibration, atomizing the liquid into tiny droplets that re-enter the reaction vessel 1, thereby efficiently capturing and dissolving the surrounding gas.

[0051] During this process, if the liquid level drops due to sampling, evaporation, etc., the self-powered piezoelectric ceramic atomizer 2 will drop synchronously, enabling continuous and stable atomization until the end of the experiment.

[0052] In summary, this invention provides a self-powered piezoelectric ceramic atomizing device, which is installed inside a reaction vessel. The core of the self-powered piezoelectric ceramic atomizing device includes a wave power generation module and a piezoelectric atomizing module. When liquid waves generated inside the reaction vessel due to stirring or natural convection impact the self-powered piezoelectric ceramic atomizing device, the wave power generation module directly converts the mechanical energy into electrical energy to drive the piezoelectric atomizing module, thereby achieving energy self-sufficiency and high energy efficiency, reducing operating energy consumption and costs, and realizing green and low-carbon operation. At the same time, the piezoelectric atomizing module atomizes the liquid into micron-sized droplets, increasing the contact area between the gas and liquid phases, allowing the gas to be quickly captured and dissolved by the droplets, accelerating the mass transfer and dissolution rate, and shortening the reaction or cultivation time. Furthermore, under the balance of gravity and buoyancy, the self-powered piezoelectric ceramic atomizer is in a floating state in the liquid of the reactor, ensuring that the self-powered piezoelectric ceramic atomizer is always in the optimal working position regardless of changes in the liquid level. This effectively avoids the "dry burning" damage and functional failure caused by the drop in liquid level of fixed devices, and ensures the continuity and reliability of long-term experiments or operation.

[0053] It should be understood that the application of the present invention is not limited to the examples above.
