Description

Method of generating heat energy by 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 isotope gases (Non-Patent Literature 1), and that observations show that during the cavitation process, many excess energy phenomena 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 the experimental results of research over 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). Furthermore, literature documents that cavitation produces bubbles, which induce high-frequency ultrasonic oscillations, create nanobubbles, and promote their rupture, triggering huge shock waves and generating high temperatures of 7,000-44,000 K (Non-Patent Literature 5).

[0052] The present application is described in further detail below with reference to the accompanying drawings and embodiments.

[0053] Please refer to Figure 1, which is a schematic diagram of the system structure of the present application. The core components of the cavitation effect thermal energy system 10 of the present application mainly include a water storage tank 101, a pressure pump 102 and a heating device 103. Among them, 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 the initial cold water as the water source for the operation of the system, and the hot water area 1012 is used to store the hot water generated during the operation of the system for subsequent use or energy recovery; the pressure pump 102 is connected to the cold water area 1011 of the water storage tank 101. , used to pressurize the cold water to a predetermined pressure, which can directly affect the subsequent cavitation effect and dynamic impact effect, and the preferred range of the predetermined pressure is between 295 kPa and 1961 kPa gauge pressure (3-20 kgf / cm^2 Gauge); 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 cross-flow furnace with rapid heating and precise temperature control, and the cross-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 within a range of less than or equal to 0.5, preferably between 0.1 and 0.3, and more preferably 0.2. The purpose of this dryness range is to maintain sufficient gas phase content to promote cavitation while not excessively reducing the thermal efficiency of the system; 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 to 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 shock occur. The dynamic shock 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.

[0054] 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.

[0055] Please refer to Figure 2, which is a schematic diagram of the steps of the method for generating thermal energy by the cavitation effect thermal energy system of the present application, which mainly includes the following steps: (1) First step S1: transporting cold water stored in a cold water area of ​​a water storage tank to a pressure pump; (2) Second step S2: using the pressure pump to pressurize the cold water to a predetermined pressure; (3) Third step S3: transporting the pressurized cold water to a heating device; (4) Fourth step S4: using the heating device to heat the pressurized cold water into hot water and water vapor; (5) Fifth step S5: allowing the hot water and water vapor to flow in the system to generate cavitation and dynamic impact, thereby generating additional thermal energy.

[0056] 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.

[0057] 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.

[0058] Referring to FIG4 , which is a schematic diagram of the arrangement of the resonant cavity of the present application system, in one embodiment, the system further includes a resonant cavity 104 connected to the heating device, the resonant cavity 104 being used to induce resonance and enhance bubble cavitation. Referring to FIG5 , which is a schematic diagram of the structure of the resonant cavity, the resonant cavity 104 further includes a plurality of cavities of different volumes, and the cross-sectional areas of the cavities (1041, 1042) of different volumes are different, and the ratio of the maximum volume to the minimum volume of the cavities is 2:10. The cavities can be, for example, a first cavity 1041 and a second cavity 1042 as shown in FIG5 . The cavities (1041, 1042) can 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 can be combined to form a change in the resonant cavity volume using shapes such as cylinders, cones, trapezoids, or triangles.

[0059] Please refer to Figure 6, which is a schematic diagram of the arrangement of the ejectors of the system of the present application. In one embodiment, the system further includes an ejector 105 connected to the heating device. The ejector 105 is used to receive the heated water and water vapor from the heating device 103 and generate strong fluid dynamic cavitation phenomenon; after the cold water flows through the heating device 103 and is heated into hot water and steam, the hot water and steam flow in the pipeline to generate a gas-liquid mixed state, such as annular flow, slug flow or stratified flow. flow), etc., and intermittently generate liquid plugs in the ejector, inducing water hammer and cavitation, resulting in a heating reaction; please refer to Figure 7, which is a schematic diagram of the structure of the ejector. In a preferred embodiment, the ejector 105 is composed of a plurality of cavities 1051, a connecting pipe 1052 and a contraction 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 expanding 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 expanding cone is larger than the inlet cross-sectional area. The different inlet and outlet cross-sectional areas of these cavities 1051 can change the pressure and flow rate of the water flow. In plain 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, and preferably, the cross-sectional area ratio of the ejector 105 is between 5 and 25; furthermore, please refer to Figure 8, which is a schematic diagram of the cavity structure of the ejector. In one embodiment, the angle θ between the generatrix 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 generatrix 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 ejector 105 can be a Venturi tube.

[0060] Please refer to Figure 9, which is a schematic diagram of the system layout of the ejector and the resonance cavity of this application. The ejector 105 can be arranged between the heating device 103 and the resonance cavity 104, or directly at the outlet of the heating device 103. In order to improve efficiency, multiple ejectors 103 can be further installed in parallel in the system.

[0061] Referring again to FIG. 10 , which is a schematic diagram of a system for deploying on / off valves in accordance with the present application, in one embodiment, the system further includes an on / off valve 106 disposed at the end of the system fluid flow path. This on / off valve 106 may be disposed before the water storage tank 101 and is configured to generate a water hammer phenomenon through its on / off action, causing the hot water and steam flowing within the system to flash and generate cavitation. Furthermore, this on / off valve 106 may be an electromagnetic pulse on / off valve that can be rapidly opened and closed at a default frequency (e.g., 10 times per second). The closed time of the on / off valve 106 is greater than the open time, and the ratio of the closed time to the open time of the on / off valve 106 is between 0.2 and 5. Each time the valve is closed, the flowing water column suddenly stops, generating a strong water hammer effect, which can enhance the cavitation effect.

[0062] Referring again to FIG. 11 , which is a schematic diagram of a system in which ultrasonic oscillators are deployed in accordance with the present application, in one embodiment, the system further includes at least one ultrasonic oscillator 107, which is disposed externally to at least one component of the system and is used to apply ultrasonic oscillations to the fluid within the component to enhance bubble cavitation. Preferably, the predetermined oscillation frequency generated by the ultrasonic oscillator 107 is in the range of 20 kHz to 40 kHz. Furthermore, the ultrasonic oscillator 107 can be mounted on the outer walls of the resonant cavity 104 and the ejector 105, as shown in this figure, or even deployed externally to the water storage tank 101. However, the aforementioned placement of the ultrasonic oscillator 107 is merely illustrative and does not limit the installation location of the ultrasonic oscillator 107. Furthermore, the ultrasonic oscillator 107 can be controlled by a dedicated controller, automatically adjusting the oscillation intensity and frequency based on the operating status of the system.

[0063] Please refer to Figure 12, which is a device layout diagram of another embodiment of the present application. As mentioned above, after the system of the present application is provided with the resonance cavity 104, the ejector 105 and the switch valve 106, the same device can be further provided based on the above-mentioned devices to enhance the cavitation effect of the system.

[0064] Referring again to FIG. 12 , in one embodiment, a second ejector 11 is provided between the resonant cavity 104 and the water storage tank 101. The second ejector 11 may be further disposed within or at the inlet of the water storage tank 101, with a cross-sectional area ratio of 5 to 25. A second ultrasonic oscillator 12 is disposed externally to the second ejector 11, and the second ultrasonic oscillator 12 provides the second ejector 11 with a predetermined oscillation frequency ranging from 20 kHz to 40 kHz. Furthermore, a third ejector 13 is disposed on the side of the resonant cavity 104. Cold water flowing out of the third ejector 13 may be injected into the side of the resonant cavity 104. The third ejector 13 may be provided with a second on-off valve 14. The cold water entering the third ejector 13 may be controlled by the second on-off valve 14 to inject the cold water into the third ejector 13. Preferably, the closing time of the second on-off valve 14 is greater than the opening time, and the ratio of the closing time to the opening time of the second on-off valve 14 is between 0.2 and 5.

[0065] As shown in FIG12 , the above-mentioned ejector 105 , the second ejector 11 and the third ejector 13 are components of the same structure, and the ultrasonic oscillator 107 and the second ultrasonic oscillator 12 are components of the same structure. Furthermore, the switch valve 106 and the second switch valve 14 are also components of the same structure.

[0066] Please refer to FIG13 , which shows another embodiment of the resonant cavity of the present application. As shown in the figure, a three-way pipe 15 can be provided in front of the resonant cavity 104. The three-way pipe 15 connects the resonant cavity 104 and the two ejectors ( 105 , 105 ′) respectively. The two ejectors ( 105 , 105 ′) are connected to a diverter pipe 16. After being diverted by the diverter pipe 16 , the hot water and the steam flow through the two ejectors ( 105 , 105 ′) respectively, and then merge at the three-way pipe 15. After the merging is completed, they flow into the resonant cavity 104, effectively enhancing the cavitation effect.
