Description

Cavitation effect thermal energy system Technical Field

[0001] The present application relates to a system for generating thermal energy by utilizing the cavitation effect of water. More specifically, the present application relates to a high-efficiency energy system that generates additional thermal energy by utilizing the cavitation phenomenon and dynamic impact effect by controlling the pressure, temperature and flow state of water. Background Art

[0002] Humanity currently faces numerous challenges in energy production and utilization. While traditional fossil fuels, such as coal, oil, and natural gas, remain the primary energy source, their use creates serious environmental challenges, including greenhouse gas emissions, air pollution, and ecological damage. Furthermore, fossil fuels are non-renewable resources with limited reserves, and long-term reliance on them poses the risk of resource depletion.

[0003] In order to meet these challenges, renewable energy technologies have developed rapidly in recent years. Clean energy technologies such as solar energy, wind energy, and hydropower have been widely used around the world. However, these technologies also have some inherent limitations, such as: (1) Intermittency: The output of solar energy and wind energy is greatly affected by weather conditions and cannot provide a stable power supply. (2) Geographical limitations: Hydropower generation requires suitable geographical conditions, and not all regions are suitable for building hydropower stations. (3) Energy storage issues: Due to the intermittent nature of renewable energy, large-scale energy storage facilities are required, which increases the complexity and cost of the system. (4) Environmental impact: Although cleaner than fossil fuels, the construction and operation of renewable energy facilities may still have an impact on the local ecological environment.

[0004] Against this backdrop, researchers are constantly searching for new energy production methods. Among these, the study of harnessing the unique physical properties of water to generate energy has garnered widespread attention. As one of Earth's most abundant resources, effectively harnessing its physical properties to generate energy could potentially provide a new solution to humanity's energy needs.

[0005] In recent years, several studies have discovered that water can exhibit unusual physical behaviors under certain conditions. For example, under extreme pressures or temperatures, certain properties of water can change significantly. These findings offer potential avenues for developing new energy technologies.

[0006] However, most of the current methods of using the special properties of water to generate energy are still in the laboratory stage and face many challenges: for example, (1) Low energy conversion efficiency: The energy generation effect observed in many experiments is weak, making it difficult to achieve large-scale application. (2) Complex system: In order to create specific physical conditions, complex equipment and a strict operating environment are often required, which increases the cost and maintenance difficulty of the system. (3) Repeatability issues: Some experimental results are difficult to reproduce stably, which is a major obstacle to the practical application of energy technology. (4) Insufficient theoretical explanation: Some observed phenomena still lack a complete theoretical explanation, which limits the further optimization and development of the technology. (5) Safety considerations: Some experimental conditions may involve extreme environments such as high pressure and high temperature, which pose potential safety risks.

[0007] Among these challenges, harnessing the cavitation phenomenon of water to generate energy is a particularly compelling research direction. Cavitation refers to the process by which bubbles form in a liquid under specific conditions, followed by the rapid collapse of these bubbles. This process can release a large amount of energy, manifesting as localized high temperatures and high pressures.

[0008] Traditionally, cavitation has been viewed primarily as a detrimental effect, potentially causing damage in, for example, ship propellers and water pumps. However, recent research has begun to explore how to harness this phenomenon to generate useful energy.

[0009] Some early studies have attempted to generate energy through sound-induced cavitation. For example, researchers designed an acoustic reactor that uses high-frequency sound waves to induce cavitation in water and observed localized high temperatures. However, this method generally has low energy conversion efficiency, making it difficult to implement on a large scale.

[0010] Another approach is to use fluid dynamics to induce cavitation. For example, using specially designed nozzles or venturis, localized low-pressure areas can be created in flowing water, inducing cavitation. This approach has the advantage of being able to be implemented in continuous-flow systems, potentially enabling large-scale energy production.

[0011] However, these early studies still face many challenges. First, how to effectively control and maintain the cavitation process is a key issue. Cavitation is inherently a dynamic and unstable process, and how to stably generate and utilize cavitation in large-scale systems remains a technical challenge.

[0012] Secondly, how to improve energy conversion efficiency is also an important issue. Although the cavitation process can release a large amount of local energy, how to effectively collect and utilize this energy remains a challenge. Many early systems performed poorly in terms of energy conversion efficiency, resulting in limited net energy gain.

[0013] Furthermore, system scalability and long-term stability also need to be addressed. Many laboratory-scale devices encounter various technical barriers when scaling up to industrial scale. Furthermore, long-term operational reliability and equipment durability are also important factors to consider.

[0014] In this context, developing a system that can effectively utilize water cavitation to generate energy while overcoming the aforementioned challenges is of great scientific significance and application value. Such a system must not only address technical challenges but also meet practical application requirements in terms of economy, reliability, and safety.

[0015] In addition, relevant literature indicates that water can stimulate nuclear reactions and produce energy and isotopic gases (Non-Patent Literature 1), and that observations show that during the cavitation process, a large amount of excess energy can be observed (Non-Patent Literature 2). Other relevant literature indicates that in cold fusion electrolysis experiments of ordinary water, a Ge(Li) detector was used to observe signals as high as 130 keV, indicating that nuclear fusion reactions occurred in ordinary water (Non-Patent Literature 3). Furthermore, literature documents the theoretical basis of cavitation-induced nuclear fusion (also known as cavitation-induced fusion, CIF) and summarizes experimental results from the past 20 years. Based on a systematic study of all available data, it is concluded that cavitation-induced nuclear fusion is feasible, operational, and can be used for commercial power generation. Research results have been presented and a commercial reactor prototype has been disclosed (Non-Patent Literature 4). Further literature describes that cavitation produces bubbles, which induce high-frequency ultrasonic oscillations, create nanobubbles, and promote their collapse, triggering huge shock waves and generating high temperatures of 7,000-44,000 K (Non-Patent Literature 5).

[0050] The present application is described in further detail below with reference to the accompanying drawings and embodiments.

[0051] Please refer to Figure 1, which is a schematic diagram of the structural composition of the cavitation effect thermal energy system of the present application. The cavitation effect thermal energy system 10 of the present application mainly includes a water storage tank 101, a pressure pump 102 and a heating device 103, wherein the water storage tank 101 is designed to have a cold water area 1011 and a hot water area 1012, which are used to store cold water and hot water respectively. The cold water area 1011 is used to store initial cold water as the water source for system operation, and the hot water area 1012 is used to store hot water generated during the operation of the system for subsequent use or energy recovery.

[0052] The pressure pump 102 is connected to the cold water area 1011 of the water storage tank 101 and is used to pressurize the cold water to a predetermined pressure. The predetermined pressure can directly affect the subsequent cavitation effect and dynamic impact effect, and the predetermined pressure range is between 295 kPa and 1961 kPa gauge pressure (3-20 kgf / cm^2 Gauge).

[0053] The heating device 103 is connected to the pressure pump 102 and is used to heat the cold water pressurized to the predetermined pressure into the hot water and water vapor. In one embodiment, the heating device 103 can be a through-flow furnace with rapid heating and precise temperature control. The through-flow furnace can adjust the heating power and water outlet temperature in real time according to system requirements to optimize the overall performance of the system. In one embodiment, the heating device 103 is configured to control the dryness of the water vapor to a range of less than or equal to 0.5, preferably between 0.1 and 0.3, and more preferably 0.2. This dryness range is intended to maintain a sufficient gas phase content to promote cavitation while not excessively reducing the thermal efficiency of the system.

[0054] Furthermore, after the cold water flows out of the cold water area 1011 of the water storage tank 101, it is pressurized to the predetermined pressure by the pressure pump 102, and then heated into the hot water and the water vapor by the heating device 103. When the hot water and the water vapor flow in the system, cavitation and dynamic impact are generated. The dynamic impact includes water hammer and resonance, thereby generating additional heat energy. Part of the hot water can flow back to the hot water area 1012 of the water storage tank 101 for storage.

[0055] As can be seen from the above, the cold water area 1011 of the water tank 101 is connected to the booster pump 102. After the cold water flows out of the cold water area 1011 of the water tank 101, it enters the booster pump 102. The booster pump 102 is connected to the heating device 103, so that the pressurized cold water can flow from the booster pump 102 to the heating device 103. In addition, the heating device 103 is connected to the hot water area 1012 of the water tank 101, so that the hot water generated after heating can flow back to the hot water area 1012 of the water tank 101.

[0056] Please refer to Figure 2, which is a schematic diagram of the working stages of the cavitation effect thermal energy system of the present application. The cavitation effect thermal energy system of the present application mainly goes through the following work process stages: (1) Initial stage S1: The cold water area 1011 of the water storage tank 101 stores cold water; (2) Pressurization stage S2: Cold water flows out of the cold water area 1011 of the water storage tank 101, and the cold water is pressurized to the predetermined pressure after passing through the pressure pump 102; (3) Heating stage S3: The pressurized cold water enters the heating device 103, and the heating device 103 heats the water to produce hot water and water vapor; (4) Cavitation and energy generation stage S4: Cavitation and dynamic impact occur when hot water and water vapor flow in the system, and additional heat energy is generated in this stage; (5) Reflux stage S5: Part of the hot water flows back to the hot water area 1012 of the water storage tank 101 for storage.

[0057] As can be seen from the above, the cavitation effect thermal energy system 10 mainly utilizes the cavitation phenomenon and dynamic impact effect of water to generate additional thermal energy, which can be used for heating, industrial heating, power generation assistance and hot water supply, improving energy efficiency, reducing traditional energy consumption, reducing carbon emissions, etc. The system adopts a partitioned storage design for hot and cold water to achieve continuous operation and heat recovery. In this case, water is used as the main working medium, which is environmentally friendly.

[0058] Please refer to Figure 3, which is a schematic diagram of another embodiment of a water storage tank. In one embodiment, the water storage tank 101 has a pipe 1013, which includes a water inlet and a drain. The water inlet is used to inject cold water, and the drain is used to discharge hot water in the pipe 1013 that has been heated by passing through the hot water area 1012. Specifically, the pipe 1013 can be further routed through the hot water area 1012, and the heat energy carried by the hot water injected into the hot water area 1012 of the water storage tank 101 can be transferred to the water in the pipe 1013 through the pipe wall of the pipe 1013. The pipe 1013 can greatly improve the thermal energy utilization efficiency of the system. In one embodiment, the pipe 1013 can be a spiral pipe coiled inside the water storage tank 101.

[0059] Please refer to Figure 4, which is a schematic diagram of the layout of the resonance cavity of the system of the present application. In this embodiment, the system also includes a resonance cavity 104 connected to the heating device. The resonance cavity 104 is used to induce resonance and enhance bubble cavitation.

[0060] Please refer to FIG5 , which is a schematic diagram of the structure of the resonant cavity. Furthermore, the resonant cavity 104 includes a plurality of cavities of different volumes arranged in sequence, and the cross-sectional areas of the cavities ( 1041 , 1042 ) of different volumes are different. The cavities may be, for example, a first cavity 1041 and a second cavity 1042 as shown in FIG5 . The cavities ( 1041 , 1042 ) may be used to induce resonance of the fluid and enhance bubble cavitation. Furthermore, the volumes of the cavities ( 1041 , 1042 ) of the resonant cavity 104 may be combined using cylindrical, conical, trapezoidal, or triangular shapes to form a variation in the resonant cavity volume.

[0061] Referring now to FIG. 6 , which illustrates the ejector placement in the system of the present application, the system further includes an ejector 105 connected to the heating device. This ejector 105 receives heated water and steam from the heating device 103 and generates intense hydrodynamic cavitation. After the cold water passes through the heating device 103 and is heated to hot water and steam, the hot water and steam flow in the pipelines, generating a mixed vapor-liquid state such as annular flow, slug flow, or stratified flow. This intermittently creates liquid slugs in the ejector, inducing water hammer and cavitation, leading to a heating reaction.

[0062] Please refer to Figure 7, which is a schematic structural diagram of the ejector shown in Figure 6. In a preferred embodiment, the ejector 105 is composed of a plurality of cavities 1051, a connecting pipe 1052 and a contracting pipe 1053, and the volumes of the cavities 1051 are different. The shape of the cavities 1051 is mainly conical, and the cavities 1051 can be divided into a tapered cone and a gradually diverging cone according to the size of the inlet and outlet. The outlet cross-sectional area of ​​the tapered cone is smaller than the inlet cross-sectional area, and the outlet cross-sectional area of ​​the gradually diverging cone is larger than the inlet cross-sectional area. The pressure and flow rate of the water flow can be changed by changing the inlet and outlet cross-sectional areas of the cavities 1051. In other words, the inlet and outlet of the ejector 105 have different cross-sectional areas, which can effectively change the pressure and flow rate of the water flow.

[0063] Furthermore, please refer to Figure 8, which is a structural schematic diagram of the cavity 1051 of the injector shown in Figure 7. In one embodiment, the angle θ between the busbar A of the tapered cone and the axis B is 5 to 30 degrees, preferably 5 to 15 degrees, and the angle θ between the busbar A of the diverging cone and the axis B is 5 to 20 degrees, preferably 5 to 10 degrees, and preferably 5 degrees; preferably, the injector 105 can be a Venturi tube.

[0064] Please refer to Figure 9, which is a schematic diagram of the structure of another embodiment of the cavitation effect thermal energy system of the present application. The cavitation effect thermal energy system of this embodiment differs from the cavitation effect thermal energy system shown in Figure 4 in that it further includes an ejector 105. The ejector 105 can be disposed between the heating device 103 and the resonant cavity 104, or directly at the outlet of the heating device 103. To improve efficiency, multiple ejectors 105 can also be installed in parallel in the system.

[0065] Please refer to FIG10 , which is a schematic diagram of the structure of another embodiment of the cavitation effect thermal energy system of the present application. The cavitation effect thermal energy system of this embodiment differs from the cavitation effect thermal energy system shown in FIG1 in that the cavitation effect thermal energy system further includes an on-off valve 106 disposed at the end of the system fluid flow path, which is used to generate water hammer through switching action, causing the hot water and steam flowing in the system to flash and produce cavitation. Furthermore, the on-off valve 106 can be an electromagnetic pulse on-off valve that can be rapidly opened and closed at a default frequency (e.g., 10 times per second). Each time it is closed, the flowing water column suddenly stops, generating a strong water hammer effect, which can enhance the cavitation effect.

[0066] Please refer to Figure 11, which is a structural diagram of another embodiment of the cavitation effect thermal energy system of the present application. The difference between the cavitation effect thermal energy system of this embodiment and the cavitation effect thermal energy system shown in Figure 9 is that the cavitation effect thermal energy system also includes at least one ultrasonic oscillator 107, which is arranged outside at least one component of the system and is used to apply ultrasonic oscillations to the fluid within the component to enhance the bubble cavitation phenomenon. Furthermore, the ultrasonic oscillator 107 can be installed on the outer walls of the resonance cavity 104 and the ejector 105, or even arranged outside the water storage tank 101, as shown in this figure. However, the above-mentioned arrangement position of the ultrasonic oscillator 107 is only for example and is not intended to limit the installation position of the ultrasonic oscillator 107. Furthermore, the ultrasonic oscillator 107 can be controlled by a dedicated controller and automatically adjust the oscillation intensity and frequency according to the operating status of the system.

[0067] Please refer to FIG12, which is another embodiment of the resonant cavity shown in FIG5. As shown in the figure, a three-way pipe 11 can be provided in front of the resonant cavity 104. The three-way pipe 11 connects the resonant cavity 104 and the two ejectors (105, 105') respectively. The two ejectors (105, 105') are connected to a diverter pipe 12. After being diverted by the diverter pipe 12, the hot water and the water vapor flow through the two ejectors (105, 105') respectively, and then merge at the three-way pipe 11. After the merging is completed, they flow into the resonant cavity 104, effectively enhancing the cavitation effect.

[0068] In summary, the cavitation effect thermal energy system 10 of the present application can not only be used for independent thermal energy production, but can also be integrated into existing large-scale energy facilities, particularly power plants. For example, the system can be applied to the steam cycle system of a thermal power plant or a nuclear power plant. Application of the present application to a power plant can not only improve the overall thermal efficiency of the power plant, but also reduce fuel consumption, lower operating costs, and further reduce greenhouse gas and pollutant emissions, thereby improving environmental performance.
