[0016] 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: 1. The steam generating device based on solar energy and calcium-based materials can convert solar energy into thermal energy through the perovskite solar collector plate, based on which the heating oil in the inner cavity of the heat pipe can be heated. The heated heating oil enters the circulation box through the heat 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 the steam can be directly discharged from the steam pipe. Through this structure, solar energy can be directly used to generate steam during the day when there is sufficient sunshine.

[0017] 2. The steam generating device based on solar energy and calcium-based materials can heat the calcium-based reaction chamber simultaneously through the heat-conducting pipe when the heat-conducting oil flows, 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 by heat, and the moisture is removed at the same time. Through the provided filter net, the decomposed calcium oxide particles and small-volume calcium hydroxide particles can be introduced into the inner cavity of the reaction component through the high-temperature resistant bellows for further reaction, and the remaining large-volume calcium hydroxide particles can remain in the inner cavity of the calcium hydrogen-based reaction chamber to continue to react.

[0018] 3. The steam generating device based on solar energy and calcium-based materials can heat the reaction component through the receiving tube, so that the small volume of calcium hydroxide particles in the inner cavity of the drum can continue to be heated and decomposed until the calcium hydroxide particles in the inner cavity of the drum can be completely decomposed into calcium oxide particles. By starting the set driving gear, the gear ring can be driven, and the drum can be driven to rotate at this time. After the drum rotates, the calcium oxide particles falling into its inner cavity will be stirred, and at the same time, the teeth will mesh with the gear, so that the turning roller can turn the calcium oxide particles, which can avoid sintering due to high temperature. The turning roller can also prevent the calcium oxide particles from sticking to the inner wall of the drum, which can ensure the subsequent recovery efficiency of the calcium oxide particles.

[0019] 4. The steam generating device based on solar energy and calcium-based materials can supply water to the atomizing nozzle through a merge ring through the set water tank and water pipe, 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 which the heat transfer oil in the inner cavity of the receiving tube can be heated, and steam can be generated by the heat energy generated by the reaction component.

[0020] 5. The steam generating device based on solar energy and calcium-based materials can regenerate calcium hydroxide particles containing a certain amount of water from the calcium oxide particles after spraying. By opening the 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, thereby achieving the recycling of the calcium hydroxide particles.

[0021] 6. The steam generating 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 electric heating fins. When the weather is bad and the perovskite solar collector cannot absorb solar energy normally, there are also backup means to generate steam during the day. The calcium oxide particles can be supplemented through the emergency energy storage bin and pneumatic conveying pipeline.

[0022] 7. The steam generating device based on solar energy and calcium-based materials can collect the heat transfer 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 box through the spiral heat exchange tube. Based on this, steam can be generated through the circulation box and the steam generating barrel. Through the provided return pipe, the heat transfer oil after the heat exchange is completed can be re-input into the heat pipe, so that the heat transfer oil can form a circulation.

[0023] 8. The steam generating device based on solar energy and calcium-based materials can generate steam both during the day and at night. During the day, the solar energy can be converted into thermal energy through the perovskite solar collector to generate steam. During the day, the thermal energy can also be used to decompose the calcium hydroxide particles in the inner cavity of the calcium-based reaction chamber to turn 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 through the heat generated. At the same time, the sprayed calcium oxide particles can be regenerated into calcium hydroxide particles. Based on this, the calcium hydroxide particles can be recycled.

At the same time, the sprayed calcium oxide particles can be regenerated into calcium hydroxide particles 12, based on which the calcium hydroxide particles 12 can be recycled.

[0030] It should be noted that the present invention is a steam generating device based on solar energy and calcium-based materials. When used during the day, the perovskite solar collector 2 converts solar energy into thermal energy, which can heat the heat transfer oil in the inner cavity of the heat pipe 10. The heat transfer oil enters the confluence base 29 through the heat transfer pipe 8, the connecting pipe 17 and the receiving pipe 16 for confluence, and then enters the inner cavity of the circulation box 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 on the top of the steam generating barrel 6. When the heat transfer oil passes through the heat transfer pipe 8 and the receiving pipe 16, it will respectively heat the calcium-based reaction chamber 3 and the reaction group 4. The inner cavity of the component 4 is heated. After the calcium-based reaction chamber 3 is heated, the calcium hydroxide particles 12 in the inner cavity thereof will react to decompose them into calcium oxide particles. The decomposed calcium oxide particles and small-volume calcium hydroxide particles 12 will pass through the filter screen 13 and the high-temperature resistant bellows 14 into the inner cavity of the drum 23, and the remaining large-volume calcium hydroxide particles 12 will continue to be decomposed by heat. After the receiving tube 16 heats the reaction component 4, the remaining calcium hydroxide particles 12 in the inner cavity of the drum 23 can be decomposed until they are all turned into calcium oxide particles. The calcium oxide particles are generated during the day and stored in the inner cavity of the drum 23. When steam needs to be generated at night, water from the water tank 18 is input to the atomizing nozzle 38 through the water pipe 19 and the merge ring 20. The atomizing nozzle 38 sprays the calcium oxide particles in the inner cavity of the drum 23 to trigger an exothermic reaction and regenerate calcium hydroxide particles 12. The heat generated after the exothermic reaction heats the heat transfer oil in the inner cavity of the receiving tube 16. At this time, steam can be generated at night, and the electric valve plate 33 is opened to input the regenerated calcium hydroxide particles 12 into the inner cavity of the calcium-based reaction chamber 3 through the feed pipe 34 and the screw conveyor 35 for recycling. When solar energy is lacking, the electric heating fins 32 are activated to directly heat the calcium hydroxide particles 12 in the inner cavity of the reaction component 4, so that they are directly produced into calcium oxide particles, which are then sprayed to generate heat and thus generate steam.
