[0001] This invention relates to the field of energy utilization technology, specifically to a device for utilizing solar steam. Background Technology

[0002] Solar energy is an emerging renewable energy source, and the rational collection and utilization of solar energy resources is beneficial to environmental protection. However, currently, most people use solar panels to convert solar energy into electricity.

[0003] Solar panels have different solar energy conversion rates depending on the raw materials used. The main raw materials for manufacturing solar panels are monocrystalline silicon, polycrystalline silicon, and amorphous silicon, with conversion rates of about 20%, 17%, and 10%, respectively. Therefore, most of the solar energy converted into heat cannot be utilized by people, which is a waste of energy and a great pity. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides a device for utilizing solar steam, which solves the problem that most of the heat energy converted from solar energy cannot be utilized by people.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for utilizing solar steam, comprising a circulator for providing circulating water;

[0006] Solar heat absorbers are used to absorb heat from sunlight.

[0007] A water replenishment pump is connected to the circulator and works with the circulator to achieve water recycling.

[0008] Multi-stage separation equipment is used to separate solar-powered circulating water and steam;

[0009] A multi-stage evaporation device for refrigerating liquid by evaporation, wherein the multi-stage separation device is connected to the circulator;

[0010] A multi-stage liquefaction device for reliquefying gas, wherein the multi-stage liquefaction device is connected to the multi-stage evaporation device.

[0011] Preferably, the multi-stage separation device includes a primary separator and a secondary separator. The input end of the primary separator is connected to the solar absorber, the output end of the primary separator is connected to the secondary separator, the liquid output end of the secondary separator is connected to the water supply pump, and the gas output end of the secondary separator is connected to the multi-stage evaporation device.

[0012] Preferably, the multi-stage evaporation equipment includes a first-effect evaporator, a second-effect evaporator, a third-effect evaporator, a fourth-effect evaporator, and a fifth-effect evaporator, which are connected in series.

[0013] Preferably, the multi-stage evaporation equipment includes at least three evaporators connected in sequence.

[0014] Preferably, the multi-stage liquefaction equipment includes a primary injection tank, a primary flash tank, a secondary injection tank, a secondary flash tank, and a tertiary flash tank, which are connected sequentially.

[0015] Preferably, the steam outlets of the primary flash tank, secondary flash tank, and tertiary flash tank are connected to the steam inlet of the multi-stage evaporation equipment.

[0016] Preferably, a water supply pipe is fixedly connected to one inlet end of the water supply pump.

[0017] Preferably, a baffle plate is fixedly connected inside the secondary separator, a nozzle is fixedly connected to the outlet end of the primary separator, the nozzle is fixedly connected to the outside of the secondary separator, a distribution plate is also fixedly connected inside the secondary separator, the baffle plate is fixedly connected to the top of the distribution plate, and a plurality of circular holes for gas-liquid separation are opened in the middle of the distribution plate.

[0018] Preferably, the first-effect evaporator, second-effect evaporator, third-effect evaporator, fourth-effect evaporator and fifth-effect evaporator are all TVR evaporators, which utilize jet heat pumps to recover part of the secondary steam.

[0019] Working Principle: The system utilizes solar heat-absorbing panels to heat water passing through them. The heated water then enters the primary separator via pipes and, after passing through the primary separator, enters the secondary separator through nozzles. In the secondary separator, baffles, a distribution plate, and a circular hole in the center of the distribution plate achieve vapor-liquid separation. The separated gas enters the first-effect evaporator and then undergoes multi-stage evaporation through a series of evaporators (first, second, third, fourth, and fifth effects). Each evaporator utilizes the residual heat energy of the previous evaporator to evaporate water at a lower pressure, forming new steam and achieving a cooling effect. The evaporators are connected in series to maximize heat energy utilization and reduce energy loss. Simultaneously, the primary injection tank connects to external steam, which passes through the primary injection tank, primary flash tank, secondary injection tank, secondary flash tank, and tertiary flash tank. Through compression and condensation, the steam is re-converted and then re-enters the first-effect evaporator to circulate with the existing steam. The liquid separated by the secondary separator flows to the makeup water pump, and then re-enters the circulator through the makeup water pump, thus completing one cycle. Through multiple cycles, the system's energy is utilized efficiently, ensuring a continuous supply of heat energy. Multi-stage liquefaction and evaporation equipment can be used for the concentration and evaporation of functional sugars, utilizing steam as an energy source and achieving energy utilization.

[0020] This invention provides a device for utilizing solar steam. It has the following beneficial effects:

[0021] This invention utilizes solar thermal energy to separate steam for the concentration and evaporation of functional sugars. It separates solar heat to produce low-temperature gas, which then enters a multi-stage evaporator. This solves the breakthrough and innovative practice problem of steam as an alternative energy source, realizes the utilization of solar steam energy, reduces the consumption of fresh steam, and reduces carbon dioxide emissions. It opens up a new and innovative path for energy reduction and emission reduction in the field of functional sugar manufacturing and has high economic value. Attached Figure Description

[0028] Solar heat absorber 2 is used to absorb heat from sunlight; the solar heat absorber 2 absorbs heat from sunlight to heat the circulating water, and some of the water is converted into steam during the heating process.

[0029] Water supply pump 16 is connected to circulator 1 and works with circulator 1 to achieve water recycling; circulator 1 provides circulating water. Water enters the circulation system from water supply pipe 15 through water supply pump 16.

[0030] A multi-stage separation device is used to separate solar-powered circulating water and steam. The multi-stage separation device includes a primary separator 3 and a secondary separator 4. The input end of the primary separator 3 is connected to the solar absorber plate 2, the output end of the primary separator 3 is connected to the secondary separator 4, the liquid output end of the secondary separator 4 is connected to the water supply pump 16, and the gas output end of the secondary separator 4 is connected to the multi-stage evaporation device.

[0031] Hot water and steam flow from the solar absorber into the primary separator 3. The primary separator initially separates the steam and water, separating most of the steam.

[0032] The remaining mixture continues to flow into the secondary separator 4, where the separation effect is further enhanced by the internal baffles 17 and distribution plate 18, ultimately achieving complete separation of water and steam.

[0033] A multi-stage evaporation unit is used to evaporate liquid for refrigeration. The multi-stage separation unit is connected to a circulator 1.

The multi-stage evaporation unit contains at least three evaporators connected in series.

[0034] The separated steam enters a multi-stage evaporation system, where it evaporates sequentially from the first-effect evaporator 5 to the fifth-effect evaporator 9. Each evaporator utilizes the residual heat energy of the previous evaporator to evaporate water at a lower pressure, forming new steam and achieving a cooling effect in the process.

[0035] The evaporators of each effect are connected in series to maximize the utilization of heat energy and reduce energy loss.

[0036] A multi-stage liquefaction unit is used to reliquefy gases. It is connected to a multi-stage evaporation unit and includes a primary injection tank 10, a primary flash tank 11, a secondary injection tank 12, a secondary flash tank 13, and a tertiary flash tank 14, connected sequentially. The multi-stage liquefaction unit and multi-stage evaporation unit can be used for the concentration and evaporation of functional sugars, utilizing steam as an energy source.

[0037] Externally supplied steam flows sequentially into the primary injection tank 10, the primary flash tank 11, the secondary injection tank 12, the secondary flash tank 13, and the tertiary flash tank 14. These devices re-convert the steam through compression and condensation.

[0038] The steam outlets of the primary flash tank 11, secondary flash tank 13, and tertiary flash tank 14 are connected to the steam inlet of the multi-stage evaporator. The steam generated by the primary injection tank 10, primary flash tank 11, secondary injection tank 12, secondary flash tank 13, and tertiary flash tank 14 re-enters the single-effect evaporator 5 and circulates with the existing steam. A water supply pump 16 has a fixed inlet end connected to a water supply pipe 15, through which appropriate water is supplied to the solar panels.

The nozzle 19 is fixedly connected to the outside of the secondary separator 4. A distribution plate 18 is also fixedly connected inside the secondary separator 4, and the baffle plate 17 is fixedly connected to the top of the distribution plate 18. Multiple circular holes 20 for gas-liquid separation are opened in the middle of the distribution plate 18. Gas-liquid separation of steam and water is achieved through the baffle plate 17 and the distribution plate 18 inside the secondary separator 4, as well as the circular holes 20 in the middle of the distribution plate 18. The gas separated by the secondary separator 4 enters the first-effect evaporator 5, and the liquid separated by the secondary separator 4 flows to the water supply pump 16, and then re-enters the circulator 1 through the water supply pump 16, thus completing one cycle.

[0041] Evaporator 5 (single effect), evaporator 6 (second effect), evaporator 7 (third effect), evaporator 8 (fourth effect), and evaporator 9 (fifth effect) are all TVR evaporators, which use jet heat pumps to recover part of the secondary steam.

[0042] A flow meter is also installed at the outlet section of the secondary separator 4 to determine the amount of steam saved. Actual verification shows that 0.02-0.05 tons of steam can be saved per ton of functional sugar.
