Description

Technical Field

[0001] This invention relates to the field of pumpless fountains and the utilization of low-grade thermal energy from water, and in particular to a pressurization device and fountain system that utilizes the thermal energy of flowing water. Background Technology

[0002] In existing fluid pressurization water supply systems, especially in scenarios such as fire-fighting water supply and landscape fountain water supply, mechanical water pump pressurization schemes are commonly used to achieve high-pressure fluid transportation. Currently, the core pressurization component of conventional pressurization devices is a high-power electric water pump. By configuring a high-power water pump device upstream of the pipeline, relying on electricity to drive the water pump, continuous pressure is provided to the fluid in the pipeline, thereby meeting the pressure requirements of high-pressure water spraying for fire extinguishing and high-pressure landscaping for landscape fountains.

[0003] While traditional electric water pump pressurization technology can achieve fluid pressurization and transportation, the entire system relies entirely on electric drive. In scenarios with no or no power, such as power outages, circuit failures, lack of power supply in the field, or power interruptions at disaster sites, the high-power water pumps cannot start and operate normally, directly causing the entire pressurized water supply system to fail. Furthermore, the long-term continuous operation of high-power water pumps results in significant energy consumption, rapid equipment wear, and a high failure rate, significantly increasing system maintenance costs and the probability of downtime for repairs.

[0004] Therefore, there is an urgent need for a pressurization device that utilizes the thermal energy of flowing water without relying on an electric system. Summary of the Invention

[0005] The purpose of this invention is to provide a pressurization device and fountain system that utilizes the thermal energy of flowing water to solve the problems existing in the prior art. By utilizing the thermal energy of flowing water to heat and vaporize liquefied gas and expand it, the fluid is pressurized, and continuous pressurization and transportation of fluid can be achieved without relying on external electricity.

[0006] To achieve the above objectives, the present invention provides the following solution: This invention provides a pressurization device utilizing the thermal energy of flowing water, comprising: a liquid storage tank, a heat exchange pipeline, and a pressure storage tank; wherein, the liquid storage tank is used to store liquefied gas, the heat exchange pipeline includes an inlet pipe and a jacket, the first end of the inlet pipe is connected to the liquid storage tank, the jacket is nested outside the inlet pipe, the second end of the inlet pipe is connected to the second end of the jacket, the first end of the jacket is sealed to the outer wall of the inlet pipe, and an inflation port is provided on the jacket near the first end of the jacket, the jacket is used to be submerged underwater, and the pressure storage tank is connected to the inflation port.

[0007] Preferably, a pressure regulating component is provided between the liquid inlet pipe and the liquid storage tank.

[0008] Preferably, the pressure tank is designed to withstand a pressure of 3MPa-6MPa.

[0009] Preferably, it further includes an elbow, the first end of which is connected to the second end of the interlayer, the second end of which is sealed, the liquid inlet pipe extends from the second end of the interlayer and extends to the second end of the elbow, and the second end of the liquid inlet pipe is spaced apart from the second end of the elbow.

[0010] The present invention also provides a fountain system, comprising: the pressurization device utilizing the thermal energy of flowing water and the water spray tank described above, wherein the water spray tank is connected to the pressure storage tank.

[0011] Preferably, it also includes a high-pressure water tank, and multiple high-pressure water tanks are connected in series between the pressure storage tank and the spray tank.

[0012] Preferably, it also includes a pressure relief valve, a water level detector, and a one-way water supply valve. The one-way water supply valve is used to connect to an external water supply device. The pressure relief valve is connected to the water level detector. When the output value of the water level detector is less than a preset value, the pressure relief valve opens. When the output value of the water level detector is greater than the preset value, the pressure relief valve closes.

[0013] Preferably, it also includes a pressure transmitter connected to the pressure tank.

[0014] Preferably, it also includes a control module, wherein the pressure relief valve, the water level detector, and the pressure transmitter are all connected to the control module.

[0015] The present invention achieves the following technical effects compared to the prior art: The pressurization device utilizing flowing water heat energy disclosed in this invention forms an inner and outer two-layer flow channel structure by setting the heat exchange pipelines in a nested manner. When the flow channel structure is filled with liquid gas or gaseous gas, it can form an inner and outer double gradient heat exchange path. The gas in the middle gas interlayer can directly absorb heat from the water flow, and its temperature is relatively high. The liquefied gas in the liquid inlet pipe first absorbs heat from the middle gas interlayer and is initially heated, thereby undergoing vaporization and expansion. After expansion, it enters the gas interlayer and can directly absorb heat from the water flow for secondary heating. The fully vaporized and expanded gas enters the pressure tank for storage, ready for subsequent use. The entire process does not rely on external electricity; it only uses the flowing water heat energy to achieve continuous gas pressurization and storage. Furthermore, this setting avoids the problems of icing on the outer wall of the liquid inlet pipe due to excessive temperature difference in the liquid gas, as well as pipeline vibration and pressure fluctuations caused by rapid vaporization, thus improving the stability and safety of the system.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The purpose of this invention is to provide a pressurization device and fountain system that utilizes the thermal energy of flowing water to solve the problems existing in the prior art. By utilizing the thermal energy of flowing water to heat and vaporize liquefied gas and expand it, the fluid is pressurized, and continuous pressurization and transportation of fluid can be achieved without relying on external electricity.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1 Please refer to Figures 1-4This embodiment provides a pressurization device utilizing the thermal energy of flowing water, comprising: a storage tank 1, an inlet pipe 2, a jacket 3, and a pressure tank 5; wherein, the storage tank 1 is used to store liquefied gas, the first end of the inlet pipe 2 is connected to the storage tank 1, the jacket 3 is nested outside the inlet pipe 2, the second end of the inlet pipe 2 is connected to the second end of the jacket 3, the first end of the jacket 3 is sealed to the outer wall of the inlet pipe 2, and an inflation port 4 is provided on the jacket 3 near the first end of the jacket 3, the jacket 3 is used to be submerged underwater, and the pressure tank 5 is connected to the inflation port 4. The liquefied gas enters the inlet pipe 2 under pressure. Due to its low temperature, it absorbs heat energy from the surrounding water as it flows through the inlet pipe 2, and then vaporizes and expands within the jacket 3. The expanded gas flows downstream into the annular space between the inlet pipe 2 and the jacket 3, which is submerged underwater. The gas in the annular space can directly exchange heat with the flowing water outside the jacket 3, thereby absorbing heat energy from the water and further expanding to generate high-pressure gas. The high-pressure gas enters the pressure tank 5 through the inflation port 4 for storage, ready for later use. This process converts the heat energy of the flowing water into the pressure energy of the gas for energy storage. It does not rely on external electricity; it utilizes only the heat energy of the flowing water to achieve continuous gas pressurization and storage. The structure is simple, the operation is stable, and it also reduces energy consumption and maintenance costs. Meanwhile, this nested arrangement of the inlet pipe 2 and the interlayer 3 creates a two-layer flow channel structure. During stable operation, the gas between the inlet pipe 2 and the interlayer 3 directly absorbs heat from the flowing water, while the gas in the inlet pipe 2 absorbs heat from the gas between the inlet pipe 2 and the interlayer 3 through the pipe wall. This forms a dual-gradient heat exchange path, requiring two heating cycles for the complete vaporization of the liquid gas. Compared to directly exposing the inlet pipe 2 to the water, this arrangement avoids the problems of icing on the outer wall of the inlet pipe 2 due to excessive temperature difference, as well as pipe vibration and pressure fluctuations caused by rapid vaporization, thus improving the stability and safety of the system. Furthermore, unlike mechanical pump pressurization, this application uses high-pressure gas to provide asynchronous energy, with power amplification capabilities, enabling megawatt-level power injection. It can achieve injection at higher heights and larger flow rates.

[0023] In one embodiment, the gas used in this device can be a known inert gas such as liquefied carbon dioxide or liquefied nitrogen.

[0024] In one embodiment, when liquefied nitrogen is used, a low-temperature pressure-resistant CV high-pressure throttling and regulating valve is used.

[0025] In one embodiment, the pressurization device utilizing the thermal energy of flowing water further includes a self-pressurizing coil. The inlet end of the self-pressurizing coil is connected to the storage tank 1, and the outlet end of the self-pressurizing coil is connected to the pressurization port of the storage tank 1. Liquid carbon dioxide circulates in the coil, absorbing ambient heat, gradually vaporizing and generating pressure, thereby self-pressurizing the liquid carbon dioxide in the storage tank 1 to ensure a stable output pressure within the storage tank 1. The self-pressurizing storage tank achieves a higher pressure, allowing it to flow by gravity into the inlet pipe.

[0026] In one embodiment, to accelerate and control the vaporization of liquid carbon dioxide in the self-pressurizing coil, a heat transfer medium is introduced into the coil to transfer heat to the cryogenic storage tank, thereby controllably speeding up the pressurization process. Furthermore, the heat transfer medium is heated antifreeze.

[0027] In one embodiment, in order to make the vaporization process of liquid carbon dioxide in the self-pressurizing coil faster and more controllable, a heating jacket or heat-conducting fins are provided on the outside of the self-pressurizing coil to improve its heat absorption efficiency. The vaporization rate and pressurization pressure can be precisely controlled by adjusting the power of the heating jacket or the number and spacing of the fins, thereby meeting the dynamic adjustment requirements of the output pressure of the liquid storage tank 1 under different working conditions.

[0028] In one embodiment, the pressure resistance of the self-boosting coil is not less than 9 MPa.

[0029] In one embodiment, a pressure regulating component is provided between the inlet pipe 2 and the storage tank 1. The pressure regulating component can control the flow rate and pressure of liquid carbon dioxide from the storage tank 1 into the inlet pipe 2, ensuring that the liquid gas in the inlet pipe 2 enters the heat exchange area at a stable and controllable flow rate, thereby avoiding local overheating or incomplete vaporization caused by flow fluctuations, and further improving the system's operational stability and heat exchange efficiency.

[0030] In one embodiment, the pressure regulating component can be a CV high-pressure throttling regulator or a pressure-reducing regulator assembly.

[0031] In one embodiment, the pressure of the heat exchange pipeline, the pressure tank 5, and the water spray system can be controlled at around 3 MPa by using the CV high-pressure throttling and stabilizing valve.

[0032] In one embodiment, the pressure tank 5 is designed to withstand a pressure of 3MPa-6MPa.

[0033] Preferably, the pressure tank 5 is designed to withstand a pressure of 3 MPa.

[0034] In one embodiment, the pressure tank 5 is equipped with safety accessories such as safety valves, rupture discs, and pressure gauges to ensure that the system can automatically depressurize under high pressure conditions, preventing equipment damage or safety accidents caused by abnormal pressure increases, thereby comprehensively improving the safety redundancy and reliability of the device operation.

[0035] In one embodiment, the pressurization device utilizing the thermal energy of flowing water further includes an elbow 6. The first end of the elbow 6 is connected to the second end of the interlayer 3, and the second end of the elbow 6 is sealed. The inlet pipe 2 extends from the second end of the interlayer 3 and extends to the second end of the elbow 6, with the second end of the inlet pipe 2 and the second end of the elbow 6 spaced apart. Due to the design of the elbow 6, the device can be assembled in a coiled, multi-stage manner to save space and improve efficiency.

[0036] In one embodiment, multiple bends 6 can be provided to further increase the number of folding stages in the heat exchange pipeline.

[0037] In one embodiment, the elbow 6 is connected to the interlayer 3 via a hafka structure 8, which facilitates quick on-site disassembly and maintenance.

[0038] In one embodiment, by adjusting the length of the inlet pipe 2, the liquid carbon dioxide can be completely vaporized within the inlet pipe 2. The completely vaporized gaseous carbon dioxide flows into the intermediate gas jacket (the space between the inlet pipe 2 and the jacket 3). As the liquid carbon dioxide flows along the inner medium pipe, it becomes low-temperature due to continuous vaporization. The lower-temperature gas absorbs heat from the higher-temperature outer wall surface, further increasing the temperature, and is then sent to the pressure tank 5 through the jacket pipeline. The temperature of the gaseous carbon dioxide in the intermediate gas jacket is higher than that of the liquid carbon dioxide in the inner medium pipe, and the outer wall temperature is higher than 0°C. This blocks direct heat conduction between the outer wall of the water-passing wall and the low-temperature liquid working fluid, preventing the outer wall of the water-passing wall from contacting the flowing water and freezing.

[0039] In one embodiment, the temperature of the outer wall surface of the heat exchange pipeline in contact with the flowing water is stabilized at 2–20°C (depending on the water temperature of the day), the interface temperature of the intermediate gas interlayer is maintained at -10–10°C, and the wall temperature of the inner medium pipe is maintained in the range of -30–-10°C. This gradient distribution ensures efficient heat transfer at each stage while effectively avoiding the potential threat of low-temperature media to the river ecosystem. This not only ensures the stable operation of the device in the river year-round but also eliminates the risk of ice crystal formation through a physical isolation mechanism, truly achieving the triple ecological commitment of "zero energy consumption, zero emissions, and zero icing".

[0040] In one embodiment, the temperature of gaseous CO2 within the intermediate gas interlayer is stabilized at 2-15°C, higher than that of liquid CO2 (-20°C to -30°C). Simultaneously, the temperature of the outer wall of interlayer 3 is maintained above 0°C to prevent icing. If icing is detected, the flow rate of carbon dioxide in the liquid inlet pipe 2 can be reduced to eliminate the icing.

[0041] Understandably, the flowing water continuously removes the cold air from the pipe wall through convection heat exchange, and the heat source is renewed by the water flow, preventing localized temperature drops that could cause heat exchange to stagnate. The internal and external heat exchange is primarily through turbulent convection, which is highly efficient.

[0042] In one embodiment, the pressure tank 5 is designed to withstand a pressure of 4 MPa.

[0043] In one embodiment, the output pressure of the pressure tank 5 is 3.2 MPa.

[0044] In one embodiment, the CV high-pressure throttling and regulating valve stably outputs 3.0 MPa of liquid CO2.

[0045] In one embodiment, when the flowing water temperature is 15°C, the liquid CO2 completely vaporizes within a 224m stroke of the inlet pipe. The temperature of the gaseous CO2 in the intermediate gas interlayer is 2~15°C, and the wall temperature of the interlayer 3 is >2°C, with no icing phenomenon. The pressure tank 5 is stabilized at 3MPa, and the pneumatic pressure regulating valve controls the injection air pressure to 3MPa, matching the water cannon with a Φ50~80mm nozzle to stably achieve water column injection at a height of over 100 meters.

[0046] like Figure 3 As shown, section 1-1' represents the LCO2 just entering the inner tube, at which point the temperature is low, approximately -20℃ at the center, increasing radially outwards to 15℃ at the tube wall; section 2-2' represents the LCO2 in the middle of the module, with a center temperature of approximately -10℃, increasing radially outwards to 15℃ at the tube wall; section 3-3' represents the LCO2 at the tail of the module, with a center temperature close to 0℃, increasing radially outwards to 15℃ at the tube wall, indicating near-complete vaporization; the vaporized gas flows through the intermediate gas interlayer, exhibiting a temperature increase trend from the inside to the outside, with heat flow from the outside in. The outer wall temperature of interlayer 3 is maintained above 2℃ to prevent freezing. Water at 15℃ flows outside the outer wall of interlayer 3, continuously providing a stable heat source through convection. If freezing occurs, the LCO2 flow rate can be reduced to eliminate it.

[0047] In one embodiment, the device can be used for fire-fighting pressurization.

[0048] Example 2 This embodiment provides a fountain system, including: the aforementioned pressurization device utilizing the thermal energy of flowing water and a water tank 10, wherein the water tank 10 is connected to a pressure storage tank 5. The water tank 10 can receive high-pressure carbon dioxide gas from the pressure storage tank 5, thereby increasing the pressure inside the water tank 10 and forcing the liquid inside the tank out to form a fountain. The entire process requires no electricity; pressurization is achieved solely through the thermal energy of flowing water, offering significant advantages such as energy saving, environmental friendliness, simple structure, and low maintenance costs.

[0049] In one embodiment, the pressurization device utilizing the thermal energy of flowing water further includes high-pressure water tanks 7, with multiple high-pressure water tanks 7 connected in series between the pressure storage tank 5 and the spray tank 10. By connecting multiple high-pressure water tanks 7 in series, the output pressure can be progressively increased and stabilized to meet the spraying requirements at higher or longer distances. Specifically, high-pressure gas is sequentially introduced into each high-pressure water tank 7, forcing the water in the high-pressure water tank 7 into the spray tank 10 sequentially. The spraying process is sequential and uninterrupted, forming a step-by-step, long-duration continuous spray. This further enhances the system's adaptability and scalability under complex working conditions.

[0050] In one embodiment, as the jetting continues, the pressure decreases. Once it reaches a certain value, the jetting stops, and the pressure is allowed to rise back to the set value, thus forming a pulsed jetting pattern. Energy is accumulated over a long period and released at high power in a short time.

[0051] In one embodiment, a pneumatic pressure regulating valve is also included. The pneumatic pressure regulating valve is installed on the pipeline between the pressure tank 5 and the water spray tank 10. The pressure of the delivered gas can be monitored and adjusted in real time through the pneumatic pressure regulating valve, and the spray height can be steplessly adjusted to more than 100 meters.

[0052] In one embodiment, a one-way valve is provided between the high-pressure water tanks 7 to prevent backflow of high-pressure gas or liquid, ensure stable one-way flow of the medium in the series pipeline, avoid system fluctuations or equipment damage caused by pressure backflow, and thus ensure the continuity and safety of the multi-stage pressurization process.

[0053] In one embodiment, the pressurization device utilizing flowing water heat energy further includes a pressure relief valve, a water level detector, and a one-way water supply valve. The one-way water supply valve is connected to an external water supply device, and the pressure relief valve is connected to the water level detector. When the output value of the water level detector is less than a preset value, the pressure relief valve opens; when the output value of the water level detector is greater than the preset value, the pressure relief valve closes. Through the linkage control of the pressure relief valve and the water level detector, the liquid level in the spray tank 10 or the high-pressure water tank 7 can be automatically maintained within a safe range. Specifically, the water level detector is installed in the high-pressure water tank 7 and can monitor the water level changes in the high-pressure water tank 7 in real time. When the water level is lower than the preset value, the pressure relief valve opens to release part of the gas pressure in the tank, allowing the external water supply device to replenish water to the tank through the one-way water supply valve. When the water level recovers to above the preset value, the pressure relief valve closes, and the system returns to normal pressurization. Through this closed-loop control mechanism, gas escape due to excessively low liquid level or the impact of excessively high liquid level on pressurization efficiency is avoided, thereby improving the reliability and automation of the system during long-term operation.

[0054] In one embodiment, the opening and closing of the pressure relief valve can be controlled manually or automatically by a preset controller to adapt to the operational needs under different working conditions.

[0055] In one embodiment, the pressurization device utilizing the thermal energy of flowing water further includes a pressure transmitter connected to the pressure storage tank 5. The pressure transmitter allows for real-time monitoring of the gas pressure within the pressure storage tank 5.

[0056] In one embodiment, the CV high-pressure throttling and stabilizing valve can be adjusted according to the pressure value detected by the pressure transmitter to stabilize the pressure in the pressure tank 5 within a preset range, thereby ensuring the smoothness and consistency of the subsequent pressurization process.

[0057] In one embodiment, the pressurization device utilizing flowing water heat energy further includes a control module 9, with a pressure relief valve, a water level detector, and a pressure transmitter all connected to the control module 9. The control module 9 receives real-time signals from the water level detector and the pressure transmitter, and automatically controls the opening and closing of the pressure relief valve and the adjustment action of the CV high-pressure throttling and stabilizing valve according to preset logic, thereby realizing closed-loop intelligent management of system pressure.

[0058] In one embodiment, the pressure transmitter provides control signals to the control module 9.

[0059] In one embodiment, the control module 9 is powered by low voltage and is used for the automatic control of pressure, flow and start-stop of the entire device. Except for the control system module, all components of the device are controlled by pneumatic passive control. The entire injection process does not require external power sources such as water pumps, mains electricity or fuel.

[0060] In one embodiment, the control module 9 is powered by a DC24V low-voltage safety power supply.

[0061] In one embodiment, the control module 9 is powered by a battery or by a low-voltage solar power source, completely disconnected from the municipal power grid, achieving fully passive operation.

[0062] In one embodiment, to improve its intelligence level, it can be linked with an atmospheric monitoring system to receive parameters such as PM2.5, temperature, humidity, wind speed, and wind direction in real time, and dynamically optimize the spraying strategy based on environmental parameters: when the PM2.5 concentration exceeds 75 μg / m³... 3 When humidity is below 40% and temperature is above 30℃, the system automatically triggers a high-frequency, short-duration spray mode to improve atomization and settling efficiency. When humidity is below 40% and temperature is above 30℃, the system extends the duration of each spray and increases the spray pressure to enhance the evaporative cooling effect. Additionally, it enables unattended holiday performance modes, enhancing the visual appeal of the landscape fountain, and can even accept voice commands from the audience.

[0063] In one embodiment, parameters such as PM10, atmospheric cooling, relative humidity, NO2, and SO2 concentrations can also be accessed in real time to dynamically optimize the injection strategy.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
