Background Art

In the current field of energy production and utilization, mankind faces many challenges. Although traditional fossil fuels, such as coal, oil and natural gas, are still the main sources of energy, their use has brought serious environmental problems, including greenhouse gas emissions, air pollution and ecological damage. In addition, fossil fuels are non-renewable resources with limited reserves. Long-term reliance on these energy sources will face the risk of resource depletion.

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:
(i) Intermittency: The output of solar and wind energy is greatly affected by weather conditions and cannot provide a stable power supply.
(ii) Geographical restrictions: Hydropower generation requires suitable geographical conditions, and not all regions are suitable for building hydropower stations.
(III) Energy storage: Due to the intermittent nature of renewable energy, large-scale energy storage facilities are required.
This increases the complexity and cost of the system.
(iv) 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.

In this context, researchers have been looking for new energy production methods. Among them, the research on using the special physical properties of water to generate energy has attracted widespread attention. As one of the most abundant resources on earth, if its physical properties can be effectively used to generate energy, it will be possible to provide a new solution to human energy needs.

In recent years, some studies have found that water may exhibit some unusual physical behaviors under certain conditions. For example, under extreme pressure or temperature, some properties of water may change significantly. These findings provide potential directions for the development of new energy technologies.

However, most current methods of using the special properties of water to generate energy are still at 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.
(ii) System complexity: 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.
(III) Repeatability issues: Some experimental results are difficult to reproduce stably, which is a major obstacle to the practical application of energy technology.
(iv) Insufficient theoretical explanation: Some observed phenomena still lack a complete theoretical explanation, which limits the further optimization and development of the technology.
(V) Safety considerations: Certain experimental conditions may involve extreme environments such as high pressure and high temperature, which may pose potential safety risks.

Among these challenges, using the cavitation phenomenon of water to generate energy is a particularly attractive research direction. Cavitation refers to the process in which bubbles form in a liquid under certain conditions and then these bubbles collapse rapidly. This process can release a large amount of energy, which manifests as local high temperature and pressure.

Traditionally, cavitation has been viewed primarily as a detrimental effect that can lead to damage in ship propellers and pumps, for example. However, research in recent years has begun to explore how the phenomenon can be harnessed to generate useful energy.

Some early studies have attempted to generate energy through sound-induced cavitation. For example, researchers have designed an acoustic reactor that uses high-frequency sound waves to generate cavitation in water and observed local high temperatures. However, the energy conversion efficiency of this method is usually low, making it difficult to achieve large-scale application.

Another approach is to use fluid dynamics to generate cavitation. For example, a specially designed nozzle or venturi can be used to create a local low-pressure area in the flowing water, thereby inducing cavitation. The advantage of this method is that it can be implemented in a continuous flow system and has the potential to be used for large-scale energy production.

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

Secondly, how to improve energy conversion efficiency is also an important issue. Although the cavitation process may 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 and produced limited net energy gains.

In addition, the scalability and long-term stability of the system are also issues that need to be addressed. Many laboratory-scale devices encounter various technical barriers when they are scaled up to industrial scale. At the same time, long-term operational reliability and equipment durability are also important factors to consider.

In this context, developing a system that can effectively utilize the cavitation phenomenon of water to generate energy while overcoming the above challenges has important scientific significance and application value. Such a system not only needs to solve technical problems, but also needs to meet the needs of practical applications in terms of economy, reliability and safety.

In addition, there are related documents that prove that water can stimulate nuclear reactions and produce energy and isotope gases (non-patent document 1), and through observation, it can be seen that many excess energy phenomena can be observed in the process of water cavitation (non-patent document 2). There are also related documents that point out that in the cold fusion electrolysis experiment of ordinary water, a Ge (Li) detector was used to observe a signal as high as 130keV, indicating that a nuclear fusion reaction occurred in ordinary water (non-patent document 3); In addition, there are documents that record the theoretical basis of cavitation-induced nuclear fusion (also known as cavitation-induced fusion, CIF), and summarize the experimental results of the past 20 years. Based on the 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. The research results are proposed and a commercial reactor prototype is disclosed (non-patent document 4); There are also documents that record that cavitation produces bubbles, causing high-frequency ultrasonic oscillations, creating nanobubbles and promoting their rupture, triggering huge shock waves and generating high temperatures of 7,000-44,000K (non-patent document 5).

The present application is further described in detail below in conjunction with the accompanying drawings.

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 a 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.

The booster 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 range of the predetermined pressure is between 295 kPa and 1961 kPa (3-20kgf/cm^2Gauge).

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 the water outlet temperature in real time according to the needs of the system 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 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 from 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.

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.

Please refer to FIG. 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 working stages:
(i) Initial stage S1: the cold water area 1011 of the water storage tank 101 stores cold water;
(ii) Pressurization stage S2: cold water flows out from 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 pressurizing pump 102;
(III) Heating stage S3: The pressurized cold water enters the heating device 103, and the heating device 103
Heating water produces hot water and water vapor;
(IV) Cavitation and energy generation stage S4: When hot water and water vapor flow in the system, cavitation and dynamic impact occur, and additional heat energy is generated in this stage;
(V) Reflux stage S5: Part of the hot water flows back to the hot water area 1012 of the water storage tank 101 for storage.

From the above, it can be seen that 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, improve energy efficiency, reduce traditional energy consumption, reduce carbon emissions, etc., and the system adopts a cold and hot water partition storage design to achieve continuous operation and heat recovery. In this case, water is used as the main working medium, which is environmentally friendly.

Please refer to FIG. 3 , which is a schematic diagram of the structure of another embodiment of a water storage tank. In one embodiment, the water storage tank 101 has a pipe 1013, and the pipe 1013 includes a water inlet and a drain, wherein the water inlet is used to inject cold water, and the drain is used to discharge the hot water in the pipe 1013 that is heated by passing through the hot water area 1012. Specifically, the pipe 1013 can be further arranged to pass 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, and in one embodiment, the pipe 1013 can be a spiral pipe coiled inside the water storage tank 101.

Please refer to FIG. 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 further includes a resonance cavity 104 connected to the heating device, and the resonance cavity 104 is used to induce resonance and enhance bubble cavitation.

Please refer to FIG. 5 , which is a schematic diagram of the structure of the resonance cavity. Further, the resonance 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 FIG. 5 . The cavities (1041, 1042) may be used to induce resonance of the fluid and enhance bubble cavitation. Further, the volumes of the cavities (1041, 1042) of the resonance cavity 104 may be combined in cylindrical, conical, trapezoidal or triangular shapes to form a change in the volume of the resonance cavity.

Please refer to FIG. 6, which is a schematic diagram of the arrangement of the ejectors of the system of the present application. In this 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 steam-liquid mixed state, such as annular flow, slug flow or stratified flow, and intermittently generate liquid plugs in the ejector, inducing water hammer and cavitation, resulting in a heating reaction.

Please refer to Figure 7 again, which is a schematic diagram of the structure 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 contraction pipe 1053, and the volumes of the cavities 1051 are different. The shapes of the cavities 1051 are 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 the 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 pressure and flow rate of the water flow can be changed by the different inlet and outlet cross-sectional areas of the cavities 1051. 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.

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 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 tapered 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.

Please refer to Fig. 9, which is a schematic diagram of the structure 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 Fig. 4 is that the cavitation effect thermal energy system further includes an ejector 105, which can be arranged between the heating device 103 and the resonance cavity 104, or directly arranged at the outlet of the heating device 103, and multiple ejectors 105 can be further installed in parallel in the system in order to improve efficiency.

Each time it is closed, the flowing water column suddenly stops to generate a strong water hammer effect, which can enhance the cavitation effect.

Please refer to FIG. 11 again, which is a schematic diagram of the structure of another embodiment of the cavitation effect thermal energy system of the present application. The difference between the cavitation effect thermal energy system of the present embodiment and the cavitation effect thermal energy system shown in FIG. 9 is that the cavitation effect thermal energy system further includes at least one ultrasonic oscillator 107, which is arranged outside at least one component of the system and is used to apply ultrasonic oscillation to the fluid in the component to enhance the bubble cavitation phenomenon. Further, the ultrasonic oscillator 107 can be installed on the outer wall of the resonance cavity 104 and the ejector 105, or even arranged outside the water storage tank 101, but the above-mentioned arrangement position of the ultrasonic oscillator 107 is only for example, and the installation position of the ultrasonic oscillator 107 is not limited here. Furthermore, the ultrasonic oscillator 107 can be controlled by a special controller, and the oscillation intensity and frequency can be automatically adjusted according to the operating state of the system.

Please refer to FIG. 12 , which is another embodiment of the resonance cavity shown in FIG. 5 . As shown in the figure, a three-way pipe 11 can be arranged in front of the resonance cavity 104. The three-way pipe 11 connects the resonance cavity 104 and the two ejectors (105, 105') respectively, and 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 resonance cavity 104, thereby effectively enhancing the cavitation effect.

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, especially power plants. For example, the system can be applied to the steam cycle system of a thermal power plant or a nuclear power plant, and the 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, reduce operating costs, and further reduce greenhouse gas and pollutant emissions, thereby improving environmental performance.
