[0002] Solar steam generation technology is an important direction for the utilization of renewable energy, and is widely used in fields such as industrial heating, seawater desalination, and district heating. Traditional steam generation systems mainly rely on fossil fuel combustion or electric heating, and have problems such as high carbon emissions and high operating costs. Although solar photothermal conversion technology can effectively utilize clean energy, its application is still limited by challenges such as light intermittency, low heat storage efficiency, and high system integration complexity.

[0003] Traditional solar steam generation devices are highly dependent on light. On rainy or cloudy days or at night, they need to rely on fossil fuel auxiliary heating, and cannot achieve the continuous supply of steam. Moreover, there is a contradiction between their energy storage density and efficiency. High heat storage density materials often have low reaction rates or high equipment complexity. At the same time, high-performance heat storage materials are costly, and some contain heavy metals or organic solvents, posing environmental risks.

[0020] Compared with the prior art, the present invention provides a steam generation device based on solar energy and calcium-based materials, which has the following beneficial effects:

[0021] 1. For the steam generation device based on solar energy and calcium-based materials, through the perovskite solar collector plate provided, solar energy can be converted into heat energy. Based on this, the heating oil in the inner cavity of the heat pipe can be heated. The heated heating oil enters the circulation tank through the heat conduction pipe, the receiving pipe and the spiral heat exchange pipe. At this time, the water source in the inner cavity of the steam generating barrel can be heated, so that steam can be directly discharged from the steam pipe. Through this structure, during the day with sufficient sunlight, solar energy can be directly used for steam generation work.

[0022] 2. For the steam generation device based on solar energy and calcium-based materials, through the heat conduction pipe provided, when the heat conduction oil flows, the calcium-based reaction chamber can be heated at the same time, so that most of the calcium hydroxide particles in the inner cavity of the honeycomb ceramic substrate are decomposed into highly active calcium oxide particles, and at the same time their moisture is removed. Through the filter screen provided, the decomposed calcium oxide particles and small-volume calcium hydroxide particles can be introduced into the inner cavity of the reaction assembly through the high-temperature resistant corrugated pipe for further reaction, and the remaining large-volume calcium hydroxide particles can remain in the inner cavity of the calcium-based reaction chamber for continuous reaction.

[0023] 3. The steam generation device based on solar energy and calcium-based materials can heat the reaction component through the provided receiving pipe, enabling the small-volume calcium hydroxide particles in the inner cavity of the rotating drum to continue to be heated and decomposed until all the calcium hydroxide particles in the inner cavity of the rotating drum are decomposed into calcium oxide particles. By starting the provided driving gear, the gear ring can be driven, and at this time, the rotating drum can be driven to rotate. After the rotating drum rotates, it will drive the calcium oxide particles falling into its inner cavity to be stirred. At the same time, through the engagement of the teeth with the gear, the turning roller can turn the calcium oxide particles, which can prevent them from sintering due to high temperature, and the turning roller can prevent the calcium oxide particles from sticking to the inner wall of the rotating drum, ensuring the subsequent recovery efficiency of the calcium oxide particles.

[0024] 4. The steam generation device based on solar energy and calcium-based materials can supply water to the atomizing nozzle through the provided water tank and water delivery pipe via the confluence ring, enabling the atomized water to spray the calcium oxide particles. At this time, the calcium oxide particles can trigger an exothermic reaction, based on which the heat-conducting oil in the inner cavity of the receiving pipe can be heated, and at this time, steam can be generated through the heat energy generated by the reaction component.

[0025] 5. After spraying, the calcium oxide particles of the steam generation device based on solar energy and calcium-based materials will regenerate calcium hydroxide particles containing a certain amount of moisture. By opening the provided electric valve plate, the calcium hydroxide particles can be re-input into the inner cavity of the calcium-based reaction chamber through the feed pipe and the screw conveyor, based on which the recycling of the calcium hydroxide particles can be achieved.

[0026] 6. The steam generation device based on solar energy and calcium-based materials can directly heat the calcium oxide particles in the inner cavity of the reaction component by starting the provided electric heating fins. When the weather is bad and the perovskite solar collector cannot normally absorb solar energy, there is also a backup means to generate steam during the day. Through the provided emergency energy storage bin and pneumatic conveying pipeline, the calcium oxide particles can be replenished.

[0027] 7. The steam generation device based on solar energy and calcium-based materials can collect the heat-conducting oil transmitted from the heat pipe, heat-conducting pipe, connecting pipe, and receiving pipe through the provided confluence base, and input it into the circulation tank through the spiral heat exchange pipe. Based on this, steam can be generated through the circulation tank and the steam generation barrel. Through the provided return pipe, the heat-conducting oil after heat exchange can be re-input to the heat pipe, enabling the heat-conducting oil to form a cycle.

[0028] 8. The steam generation device based on solar energy and calcium-based materials can generate steam both during the day and at night. During the day, the perovskite solar collector can convert solar energy into heat energy to generate steam. During the day, the heat energy can also decompose the calcium hydroxide particles in the inner cavity of the calcium-based reaction chamber into calcium oxide particles. When there is no light at night, the calcium oxide particles can be sprayed to generate heat. Based on this, steam can be generated at night by the generated heat. At the same time, the sprayed calcium oxide particles can be regenerated into calcium hydroxide particles, and based on this, the calcium hydroxide particles can be recycled.

[0037] By setting the perovskite solar collector 2, solar energy can be converted into heat energy. Based on this, the heating oil in the inner cavity of the heat pipe 10 can be heated. The heated heating oil enters the circulation tank 5 through the heat conduction tube 8, the receiving tube 16, and the spiral heat exchange tube 36. At this time, the water source in the inner cavity of the steam generation barrel 6 can be heated, so that steam can be directly discharged from the steam pipe 7. Through this structure, during the day with sufficient sunlight, solar energy can be directly used for steam generation work;

[0038] By setting the heat conduction tube 8, when the heat conduction oil flows, the calcium-based reaction chamber 3 can be heated at the same time, so that most of the calcium hydroxide particles 12 in the inner cavity of the honeycomb ceramic substrate 11 are decomposed into highly active calcium oxide particles, and their moisture is removed at the same time. By setting the filter screen 13, the decomposed calcium oxide particles and small-volume calcium hydroxide particles 12 can be introduced into the inner cavity of the reaction assembly 4 through the high-temperature resistant corrugated pipe 14 for further reaction, and the remaining large-volume calcium hydroxide particles 12 can remain in the inner cavity of the calcium-based reaction chamber 3 to continue the reaction.

[0039] Example Two:

[0040] As Figures 1-4As shown in the figure, a steam generation device based on solar energy and calcium-based materials. At the top of the outer wall of the reaction component 4, a water tank 18 and an emergency energy storage bin 21 are installed. At the top of the inner cavity of the reaction component 4, an atomizing nozzle 38 is installed. In the inner cavity of the reaction component 4, a rotating cylinder 23 is rotatably connected. In the inner cavity of the rotating cylinder 23, a material turning roller 26 is rotatably connected. In the center of the top of the reaction component 4, a current collecting ring 20 is installed. The current collecting ring 20 is communicated with the inner cavity of the atomizing nozzle 38. At the top of the water tank 18, a water delivery pipe 19 is installed. The other end of the water delivery pipe 19 is installed on the outer wall of the current collecting ring 20. A valve is flange-connected to the outer wall of the water delivery pipe 19. At the top of the emergency energy storage bin 21, a pneumatic conveying pipeline 22 is installed. The other end of the pneumatic conveying pipeline 22 is installed on the top of the reaction component 4. Calcium oxide particles are stored in the inner cavity of the emergency energy storage bin 21. At the top of the inner cavity of the rotating cylinder 23, a toothed tooth 24 is installed. On the side of the toothed tooth 24, a gear 25 is meshed. At the center of the bottom of the gear 25, a material turning roller 26 is installed. The material turning roller 26 is rotatably connected in the inner cavity of the rotating cylinder 23. At the top of the inner cavity of the rotating cylinder 23, a baffle 27 is installed. The top of the gear 25 is rotatably connected to the bottom of the baffle 27. On the top of the baffle 27, a material guiding groove 28 is opened. The bottom of the receiving pipe 16 is installed on the top of the current collecting base 29 and is communicated with its inner cavity. The driving gear 30 is driven by a driving motor. The driving motor is installed at the bottom of the current collecting base 29. The driving gear 30 and the gear ring 31 are meshed. The rotating cylinder 23 is a cavity structure with the top and bottom communicated with the outside. The bottom of the rotating cylinder 23 is installed on the top of the gear ring 31. The bottom of the material turning roller 26 is rotatably connected to the top of the current collecting base 29;

[0041] By setting the receiving pipe 16, the reaction component 4 can be heated, so that the small-volume calcium hydroxide particles 12 in the inner cavity of the rotating cylinder 23 can continue to be heated for decomposition until all the calcium hydroxide particles 12 in the inner cavity of the rotating cylinder 23 are decomposed into calcium oxide particles. By starting the set driving gear 30, the gear ring 31 can be driven. At this time, the rotating cylinder 23 can be driven to rotate. After the rotating cylinder 23 rotates, it will drive the calcium oxide particles falling into its inner cavity to be stirred. At the same time, through the meshing of the toothed tooth 24 and the gear 25, the material turning roller 26 can turn over the calcium oxide particles, which can avoid the sintering phenomenon due to high temperature, and the material turning roller 26 can prevent the calcium oxide particles from sticking to the inner wall of the rotating cylinder 23, and can ensure the subsequent recovery efficiency of the calcium oxide particles;

[0042] By setting the water tank 18 and the water delivery pipe 19, the atomizing nozzle 38 can be supplied with water through the current collecting ring 20, so that the atomized water can spray the calcium oxide particles. At this time, the calcium oxide particles can trigger an exothermic reaction. Based on this, the heat-conducting oil in the inner cavity of the receiving pipe 16 can be heated. At this time, steam can be generated by the heat energy generated by the reaction component 4.

[0043] Example Three:

[0044] As Figures 1-4 shown, a steam generation device based on solar energy and calcium-based materials. A driving gear 30 is rotatably connected to the side of the top of the confluence base 29. A gear ring 31 is rotatably connected to the center of the top of the confluence base 29. Electric heating fins 32 are installed on the top of the confluence base 29. An electric valve plate 33 is installed on the top of the confluence base 29. A screw conveyor 35 is arranged on the side of the confluence base 29. A feed pipe 34 is installed at the bottom of the electric valve plate 33. The bottom of the screw conveyor 35 is installed on the top of the feed pipe 34. The top of the screw conveyor 35 is installed on the side of the calcium-based reaction chamber 3. A base 1 is installed at the bottom of the confluence base 29. A circulation tank 5 is also installed on the top of the base 1. Two spiral heat exchange pipes 36 are symmetrically installed on both sides of the confluence base 29. The other ends of the spiral heat exchange pipes 36 are installed on both sides of the outer wall of the circulation tank 5. A liquid return pipe 37 is also installed on the outer wall of the circulation tank 5. The other end of the liquid return pipe 37 is installed on the outer wall of one of the heat pipes 10. The bottom of the steam generation barrel 6 is installed on the top of the circulation tank 5. The circulation tank 5 is used to heat the water in the inner cavity of the steam generation barrel 6 to generate steam. A steam pipe 7 is installed on the top of the steam generation barrel 6. A sealing plug is inserted into the top of the steam generation barrel 6;

[0045] The calcium oxide particles after spraying will regenerate calcium hydroxide particles 12 containing a certain amount of moisture. By opening the set electric valve plate 33, the calcium hydroxide particles 12 can be re-input into the inner cavity of the calcium-based reaction chamber 3 through the feed pipe 34 and the screw conveyor 35. Based on this, the recycling of the calcium hydroxide particles 12 can be achieved;

[0046] By starting the set electric heating fins 32, the calcium oxide particles in the inner cavity of the reaction assembly 4 can be directly heated. When the weather is bad and the perovskite solar collector 2 cannot normally absorb solar energy, there is also a backup means to generate steam during the day. Through the set emergency energy storage bin 21 and the pneumatic conveying pipeline 22, the calcium oxide particles can be replenished;

[0047] Through the set confluence base 29, the heat-conducting oil transmitted from the heat pipes 10, the heat-conducting pipes 8, the connecting pipes 17 and the receiving pipes 16 can be collected and input into the circulation tank 5 through the spiral heat exchange pipes 36. Based on this, steam can be generated through the circulation tank 5 and the steam generation barrel 6. Through the set liquid return pipe 37, the heat-conducting oil after heat exchange can be re-input to the heat pipe 10, so that the heat-conducting oil can form a cycle;

[0048] This device can generate steam both during the day and at night. During the day, the perovskite solar heat collector 2 can convert solar energy into heat energy to generate steam. During the day, the heat energy can also be used to thermally decompose the calcium hydroxide particles 12 in the inner cavity of the calcium-based reaction chamber 3, turning them into calcium oxide particles. When there is no light at night, the calcium oxide particles can be sprayed to generate heat. Based on this, steam can be generated at night using the generated heat. At the same time, the sprayed calcium oxide particles can be regenerated into calcium hydroxide particles 12. Based on this, the calcium hydroxide particles 12 can be recycled.

[0049] It should be noted that the present invention is a steam generation device based on solar energy and calcium-based materials. When used during the day, the perovskite solar heat collector 2 converts solar energy into heat energy. At this time, the heat-conducting oil in the inner cavity of the heat pipe 10 can be heated. The heat-conducting oil enters the confluence base 29 through the heat-conducting pipe 8, the connecting pipe 17, and the receiving pipe 16 for confluence, and then enters the inner cavity of the circulation tank 5 through the spiral heat exchange pipe 36 for heat exchange treatment. At this time, steam can be generated during the day, and the steam can be directly discharged from the steam pipe 7 at the top of the steam generation barrel 6. When the heat-conducting oil passes through the heat-conducting pipe 8 and the receiving pipe 16, it will respectively heat the inner cavities of the calcium-based reaction chamber 3 and the reaction assembly 4. After the calcium-based reaction chamber 3 is heated, the calcium hydroxide particles 12 in its inner cavity will react and decompose into calcium oxide particles. The decomposed calcium oxide particles and the small-volume calcium hydroxide particles 12 will enter the inner cavity of the rotating cylinder 23 through the filter screen 13 and the high-temperature resistant corrugated pipe 14, and the remaining large-volume calcium hydroxide particles 12 will continue to be thermally decomposed. After the receiving pipe 16 heats the reaction assembly 4, the remaining calcium hydroxide particles 12 in the inner cavity of the rotating cylinder 23 can be decomposed until they all become calcium oxide particles. The calcium oxide particles generated during the day are stored in the inner cavity of the rotating cylinder 23;

[0050] When steam needs to be generated at night, through the water delivery pipe 19, the water in the water tank 18 is input into the atomizing nozzle 38 through the confluence ring 20. The atomizing nozzle 38 sprays the calcium oxide particles in the inner cavity of the rotating cylinder 23 to trigger an exothermic reaction and regenerate into calcium hydroxide particles 12. The heat generated after the exothermic reaction heats the heat-conducting oil in the inner cavity of the receiving pipe 16. At this time, steam can be generated at night. Open the electric valve plate 33, and the regenerated calcium hydroxide particles 12 are input into the inner cavity of the calcium-based reaction chamber 3 through the feeding pipe 34 and the screw conveyor 35 for recycling;

[0051] When there is a lack of solar energy, the electric heating fins 32 are started to directly heat the calcium hydroxide particles 12 in the inner cavity of the reaction assembly 4, turning them directly into calcium oxide particles, and then spraying them to generate heat and thus generate steam.
