Description

Technical Field

[0001] This utility model relates to the field of energy equipment, and in particular to a heating device that combines solar energy with ice crystals to block backflow propagation. Background Technology

[0002] Liquids whose temperature is below their freezing point but do not solidify or crystallize are called supercooled liquids. Supercooled liquids are unstable; adding even a small amount of the substance's crystals can induce crystallization and raise the temperature of the supercooled liquid back to its freezing point. This unstable state, which changes rapidly under slight disturbances, is called a metastable state. When a saturated solution is slowly cooled in an appropriate manner, it can become supersaturated without precipitating solute crystals; this phenomenon is also called supercooling, and such a solution is called a supercooled solution. Supercooled solutions are also unstable; when the temperature drops below the freezing point, if there are no crystal nuclei in the water to crystallize, it will not freeze even below 0°C. If a small amount of crystal nuclei is added at this point, it will immediately freeze.

[0003] Existing ice crystal propagation prevention devices typically use cooling water flowing over the outer wall of a subcooled water pipe to heat the ice crystals and block their backflow. However, the heating process involves an ice layer on the inner wall of the pipe on one side and cooling water on the other. This results in unstable cooling water temperatures, long heating times, and inconsistent effectiveness. By incorporating a solar photovoltaic system and winding a coil around the subcooled water pipe, electromagnetic induction heating is used to melt the ice layer on the inner wall. The coil is energized by monitoring the water flow rate in the subcooled water pipe (increased water flow due to ice layer on the pipe wall energizes the coil, melting the ice). This technology offers rapid heating, significant results, and substantial economic and social value. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a heating device that combines solar energy to block ice crystal backflow propagation. It aims to improve the existing ice crystal propagation prevention device, which has an ice layer on one side of the pipe wall and cooling water on the other side during the heating process. The cooling water temperature is unstable, the heating time is long, and the effect cannot be guaranteed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heating device for blocking ice crystals and countercurrent propagation using solar energy, comprising an ice crystal blocking countercurrent propagation heating device, wherein a solar photovoltaic system is installed on the ice crystal blocking countercurrent propagation heating device, wherein a solar photovoltaic panel, a battery, an inverter and a control device are installed inside the solar photovoltaic system, wherein an ice crystal blocking countercurrent propagation heating device is provided with a first subcooled water pipe, an energized coil, a subcooled water pipe insulation layer and a subcooled water pipe protective layer, wherein a flow rate sensor is installed at the inlet of the ice crystal blocking countercurrent propagation heating device, wherein one end of the first subcooled water pipe is fixedly connected to a second subcooled water pipe, and the other end of the first subcooled water pipe is fixedly connected to an ultrasonic crystal promoter, wherein one end of the second subcooled water pipe is fixedly connected to a preheater outlet pipe, and the other end of the second subcooled water pipe is fixedly connected to an ice slurry pipe, wherein a subcooled water plate heat exchanger is installed in the middle of the preheater outlet pipe, and one end of the ice slurry pipe is fixedly connected to an ice storage tank.

[0006] Furthermore, after receiving water from the preheater outlet pipe, the subcooled water plate heat exchanger then transports the subcooled water to the ice crystal blocking backflow heating device via the second subcooled water pipe.

[0007] Furthermore, the ice crystal blocking backflow propagation heating device is additionally equipped with a solar photovoltaic system, including solar photovoltaic panels, a battery, an inverter, and a control device; a flow rate sensor is installed at the inlet of the ice crystal blocking backflow propagation heating device.

[0008] Furthermore, the ultrasonic crystallizer receives supercooled water that has passed through the ice crystal blocking backflow heating device. Inside the crystallizer, the solid solute in the supersaturated solution can precipitate rapidly and gently, while simultaneously enhancing crystal growth, generating ice slurry, which is then transported to an ice storage tank for ice storage via an ice slurry pipe.

[0009] Furthermore, the ice crystal blocking backflow propagation heating device involves wrapping an energized coil around the outer wall of the subcooled water pipe. Through the principle of electromagnetic induction heating, the ice layer on the inner side of the pipe wall is melted. The coil is energized and de-energized by monitoring the water flow rate in the subcooled water pipe. An insulation layer for the subcooled water pipe is added outside the energized coil, and a protective layer for the subcooled water pipe is added outside the insulation layer to protect the water pipe.

[0010] This utility model has the following beneficial effects:

[0011] 1. In this utility model, cooling water is heated by flowing through the outer wall of the subcooled water pipe. This method has a wide range of applications, is easy to operate, and is environmentally friendly and energy-saving. It solves the problem of unstable subcooled water conditions after a heat exchanger, which can lead to phase change and icing. Ice crystals act as nucleating agents for subcooled water, accelerating its freezing and ultimately causing icing inside the heat exchanger, thus affecting heat exchange. Attached Figure Description

[0017] Reference Figure 1 and Figure 2This utility model provides an embodiment of a heating device that combines solar energy with ice crystal blocking backflow propagation heating device 2, characterized in that: a solar photovoltaic system 1 is installed on the ice crystal blocking backflow propagation heating device 2, the solar photovoltaic system 1 is internally provided with a solar photovoltaic panel 11, a battery 12, an inverter 13 and a control device 14, and the ice crystal blocking backflow propagation heating device 2 is internally provided with a subcooled water pipe 21, an energized coil 22, a subcooled water pipe insulation layer 23 and a subcooled water pipe. The protective layer 24 has a flow rate sensor 3 installed at the inlet of the ice crystal blocking backflow heating device 2. One end of the subcooled water pipe 1 21 is fixedly connected to the subcooled water pipe 2 8, and the other end of the subcooled water pipe 1 21 is fixedly connected to the ultrasonic crystallizer 5. One end of the subcooled water pipe 2 8 is fixedly connected to the preheater outlet pipe 7, and the other end of the subcooled water pipe 2 8 is fixedly connected to the ice slurry pipe 9. The middle of the preheater outlet pipe 7 is equipped with a subcooled water heat exchanger 4. One end of the ice slurry pipe 9 is fixedly connected to an ice storage tank 6. The subcooled water heat exchanger 4 receives water from the preheater outlet pipe 7. After heat exchange with the water, the supercooled water is transported to the ice crystal blocking countercurrent propagation heating device 2 through the supercooled water pipe 28. The ice crystal blocking countercurrent propagation heating device 2 is additionally equipped with a solar photovoltaic system 1, including solar photovoltaic panels 11, batteries 12, inverters 13, and control devices 14. A flow rate sensor 3 is installed at the inlet of the ice crystal blocking countercurrent propagation heating device 2. An ultrasonic crystal promoter 5 receives the supercooled water that has passed through the ice crystal blocking countercurrent propagation heating device 2. In the crystal promoter, solid solutes in the supersaturated solution can be generated. Rapid and gentle sedimentation can simultaneously enhance crystal growth, generate ice slurry, and transport it to the ice storage tank 6 through the ice slurry pipe 9 for ice storage. The ice crystal blocking backflow heating device 2 is to wrap an energized coil 22 around the outer wall of the supercooled water pipe 21. Through the principle of electromagnetic induction heating, the ice layer on the inner side of the pipe wall is dissolved. By monitoring the water flow rate of the supercooled water pipe, the coil is energized and de-energized. An insulation layer 23 for the supercooled water pipe is added to the outside of the energized coil 22, and a protective layer 24 for the supercooled water pipe is added to the outside of the insulation layer to protect the water pipe.

[0018] Specifically, the solar photovoltaic panel 11 absorbs solar energy and generates electricity, which is stored in the battery 12 and converted into a suitable voltage by the inverter 13. The control device 14 controls the start and stop of the ice crystal blocking backflow heating device 2 based on the flow rate monitored by the flow rate sensor 3. This device mainly relies on the principle of electromagnetic induction heating through the energized coil 22 to melt the ice layer on the inner wall of the subcooled water pipe 21, thereby preventing the ice crystals from propagating backflow. During the heating process, the outside of the subcooled water pipe 21 is covered with a subcooled water pipe insulation layer 23 to further reduce heat loss, and the subcooled water pipe protective layer 24 provides heat protection. For additional protection, the water heated by the preheater outlet pipe 7 enters the subcooled water plate heat exchanger 4. The subcooled water formed after heat exchange enters the ice crystal blocking backflow heating device 2 through the subcooled water pipe 8 for treatment. Subsequently, the ultrasonic crystal promoter 5 acts on the heated subcooled water to promote the uniform precipitation of solid solutes in the supersaturated solution and enhance crystal growth, eventually generating ice slurry, which is then transported to the ice storage tank 6 for storage through the ice slurry pipe 9. Combining solar power supply, intelligent flow rate monitoring and electromagnetic heating technology, it has the advantages of faster heating speed and higher energy efficiency compared to the traditional method of heating by cooling water.

[0019] Working principle: When the heating device that combines solar energy to block the backflow of ice crystals starts to operate, firstly, through the solar photovoltaic system 1, the coil is wound around the subcooled water pipe 21 and the subcooled water pipe 8. Using the principle of electromagnetic induction heating, the ice layer on the inner side of the pipe wall is melted. The flow rate sensor 3 monitors the water flow rate in the subcooled water pipe and controls the on / off state of the coil (if there is ice on the pipe wall, the water flow rate increases, the coil is energized, and the ice is melted). The technology has a fast heating speed. The solar photovoltaic panel 11 absorbs solar energy to generate electricity, which is stored in the battery 12. The flow rate sensor 3 controls the start and stop of the heating device that blocks the backflow of ice crystals. The technology uses the principle of electromagnetic induction heating to melt the ice layer on the inner side of the pipe wall. Compared with the method of heating by cooling water flowing through the outer wall of the subcooled water pipe 21, this technology has the characteristics of fast heating speed and significant effect.
