DETAILED DESCRIPTION

[0033] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0035] As shown in Figure 1 The present application discloses a heat storage device 1, which comprises: a heat source collecting assembly, the heat source collecting assembly comprising a solar energy collecting unit, an industrial waste heat collecting unit, a geothermal energy collecting unit and a wind energy collecting unit; a heat storage part 2, the heat storage part 2 being used for storing heat collected by the heat source collecting assembly; a heat source management part 3, the heat source management part 3 being connected with the heat source collecting assembly and the heat storage part 2 respectively, and being used for transferring heat collected by the heat source collecting assembly into the heat storage part 2; and a load end, the load end being connected with the heat storage part 2, and being used for consuming heat in the heat storage part 2. The load end refers to equipment or area consuming heat, such as residential area, office building, etc.

[0036] The present application collects excess heat in the heat energy enrichment area and heat during the heat energy surplus period by the heat source collecting assembly, stores heat collected by the heat source collecting assembly in the heat storage part 2, supplies heat from the heat storage part 2 to the load end when the load end needs heat, which not only makes the excess heat in the heat energy enrichment area and the heat energy surplus period be effectively utilized, solves the problem of mismatch between heat production and heat demand, avoids waste of the excess heat in the heat energy enrichment area and the heat energy surplus period, and saves consumption of additional energy when the load end needs heat, thereby reducing heat production and heat supply cost; and the present application integrates, balances and buffers heat of different types and different sources collected by the heat source collecting assembly through the heat source management part 3, slows down the transmission speed of heat, makes heat be gradually and evenly transmitted to the heat storage part 2, and enables heat in the heat storage part 2 to be evenly distributed and maintained at a relatively stable level, which avoids heat loss caused by local overheating or overcooling of the heat storage part 2, reduces loss of heat during storage in the heat storage part 2, and further realizes effective utilization of heat.

[0037] Meanwhile, by arranging the heat source management part 3, different types and different grades of heat collected by the heat collection assembly can be mixed before entering the heat storage part 2, specifically in the process of being transferred to the heat storage part 2 by the heat source management part 3, so that the temperature of the heat transferred to the heat storage part 2 is relatively uniform, thereby reducing the high-temperature impact of the heat on the heat storage part 2, reducing the probability of damage of the heat storage part 2 due to overheating of a local area, improving the heat storage capacity of the heat storage part 2, and prolonging the service life of the heat storage part 2.

[0038] In the utility model, the heat source management part 3 is connected with the heat storage part 2 and the heat collection assembly, and the heat storage part 2 is connected with the load end, which does not mean that the above structure must be connected, and the connection only means that heat can be transferred from the heat collection assembly to the heat source management part 3, from the heat source management part 3 to the heat storage part 2, and from the heat storage part 2 to the load end, and whether it needs to be connected depends on the working condition. The heat transfer between the heat source management part 3 and the heat storage part 2, between the heat source management part 3 and the heat collection assembly, and between the heat storage part 2 and the load end has multiple forms, which can be realized by arranging a heat exchanger between the above two structures or arranging the above two structures adjacently and realizing heat transfer by arranging a heat conduction surface. Or other structures that can realize heat transfer can also be used.

[0039] In the utility model, the heat source collection assembly includes a solar energy collection unit, an industrial waste heat collection unit (industrial waste heat can also be collected), a geothermal energy collection unit, and a wind energy collection unit. It should be noted that the heat source collection assembly does not only include the above types of collection units, and other heat sources with excess capacity such as tidal energy can also be equipped with corresponding collection units.

[0040] It should be noted that although the utility model claims "solar energy collection unit, wind energy collection unit", it does not mean collecting solar energy and wind energy, but collecting heat generated by solar energy and wind energy. For example, the collection in the solar energy collection unit means collecting heat generated by solar energy, and heat exists in multiple forms, such as steam generated by solar energy, for example, Figure 1As shown, at this time, the solar energy collecting unit includes a solar energy accumulator 20, which is configured to generate steam or hot water by using solar energy, and the solar energy accumulator 20 is connected to the water pipe 19 in the heat source management part 3 in communication, and the solar energy accumulator 20, the water pipe 19 and the water pipe 19 in the heat source management part 3 form a circulating loop, that is, the heat carried by the steam or hot water is transmitted to the heat source management part 3 by flowing in the heat source management part 3, and in order to further improve the heat transfer efficiency, two circulating loops can be provided, one of which is connected to the input end and the output end of the solar energy accumulator 20, and part of the water pipe 19 is located in the heat source management part 3, and the other of which is the water pipe 19 located in the heat source management part 3, and the heat generated by the solar energy is transmitted by heat exchange of the two circulating loops (for details of the heat exchange structure, refer to the existing heat exchanger, which will not be described here).

[0041] The specific structure of other types of collecting units can be a conveying pipeline or a conveying vehicle (the conveying vehicle collects heat from the heat source and then conveys the heat to the heat source management part 3, and a pipeline connection also needs to be established during the process of conveying the heat to the heat source management part 3 by the conveying vehicle). Figure 1 As shown, the heat source management part 3 is provided with a distribution pipe 4, one end of the distribution pipe 4 extends into the heat source management part 3, a plurality of nozzles 5 are uniformly arranged on the distribution pipe 4, and the other end of the distribution pipe 4 extends out of the heat source management part 3 and is connected to the conveying vehicle or the conveying pipeline, that is, the heat collected by the industrial waste heat collecting unit can be conveyed to the heat source management part 3 by the conveying pipeline + distribution pipe 4 or the conveying vehicle + distribution pipe 4. Among them, the heat source management part 3 can also not be provided with nozzles 5 in the distribution pipe 4, and a heat exchange medium is filled in the heat source management part 3, so that the heat collected by the heat collecting assembly is transmitted to the heat exchange medium, and the heat exchange medium transmits the absorbed heat to the heat storage part 2.

[0042] The enterprises with industrial waste heat or excess steam can store the excess heat into the heat storage part 2 through the conveying vehicle such as the mobile heat storage vehicle or the conveying pipeline, which ensures that the heat can be stored when the heat demand is small and the heat production is surplus. Moreover, the solar energy collecting assembly collects the heat generated by using solar energy, which is equivalent to realizing indirect storage of solar energy, achieving the purpose of energy saving and emission reduction, and reducing the problems of dust and pollutant gas emission caused by single use of the boiler to produce heat.

[0043] The structure of the heat storage part 2 in the utility model has various forms, such as Figure 1As shown, the heat storage part 2 includes a first heat storage chamber, and the first heat storage chamber is filled with a phase change heat storage material 9; at this time, after the heat source management part 3 transmits heat to the first heat storage chamber, the heat is absorbed by the phase change heat storage material 9, and the heat storage capacity of the heat storage part 2 is improved by the phase change capacity of the phase change heat storage material 9. And / or, the heat storage part 2 includes a first heat exchanger, the input end of the first heat exchanger is in communication with the heat source management part 3, and the input end of the first heat exchanger is in communication with the underground soil; at this time, the underground soil is equivalent to the heat storage area of the heat storage device 1. The first heat exchanger is buried underground, and the first heat exchanger can be a U-shaped tube, a sleeve type, a horizontal pipe type and the like.

[0044] The position of the heat source management part 3 in the utility model has various setting forms, for example, the heat source management part 3 can be arranged below the heat storage part 2; this makes the heat in the heat source management part 3 directly transmitted upward to the heat storage part 2, so that the heat can be more uniformly distributed in the heat storage part 2, avoiding the problem that the heat is not uniformly distributed in the heat storage part 2 and cannot continuously and stably output uniform heat, and improving the heat supply capacity of the heat storage device 1 in the utility model; if the heat source management part 3 is arranged above the heat storage part 2, the heat will tend to escape upward, causing the "short circuit" phenomenon that the upper part of the heat storage part 2 is too high in temperature and the lower part is insufficient in temperature, thereby reducing the overall heat storage effect of the heat storage part 2.

[0045] Alternatively, the heat source management part 3 can also not be arranged below the heat storage part 2, but arranged outside the heat storage part 2, and the heat source management part 3 is arranged around the outside of the heat storage part 2; at this time, since the heat storage part 2 is provided with a ring of heat source management parts 3 outside, the contact area of the heat source management part 3 and the heat source collecting assembly is increased, the rate of heat transfer from the heat source collecting assembly to the heat source management part 3 is improved, and the problem that most of the heat is dissipated to the outside during the transmission process due to the slow transmission rate is avoided as much as possible. However, it should be noted that when the heat storage part 2 is provided with a ring of heat source management parts 3 outside, the heat exchange pipeline (or heat transfer pipeline) between the heat storage part 2 and the load end needs to avoid the heat source management part 3, for example, the heat exchange pipeline between the heat storage part 2 and the load end is arranged above or below the heat source management part 3, so as to ensure that the functions of the heat storage part 2 and the heat source management part 3 can be smoothly realized.

[0046] The setting mode of the heat source management part 3 is not limited to the above-mentioned case, and other distribution modes that do not hinder the normal function realization of the heat storage device 1 can also be used.

[0047] The heat storage unit 2 and the heat source management unit 3 in this utility model can be located underground, which reduces the above-ground area occupied by the heat storage device 1, allowing other equipment to be arranged in the above-ground area of ​​the heat storage device 1, thus saving land resources; and / or, the heat storage unit 2 and the heat source management unit 3 are located close to the heat-intensive area, i.e. the load end with high heat demand, which shortens the distance between the heat storage unit 2 and the load end with high heat demand, reduces the large number of pipes required over long distances, and lowers the heating cost of the heat storage device 1 in this utility model.

[0048] In this invention, heat transfer between the heat storage unit 2 and the heat source management unit 3 can be achieved through a heat exchanger, or other structures capable of heat transfer, such as... Figure 1 As shown, a heat-conducting pipe 6 is provided inside the heat source management section 3. A portion of the heat-conducting pipe 6 is located inside the heat source management section 3, and another portion is located inside the heat storage section 2. After absorbing heat from the heat source management section 3, the heat-conducting pipe 6 transfers the heat to the heat storage section 2 via its portion located inside the heat storage section 2. Specifically, the heat-conducting pipe 6 can be a T-shaped heat-conducting pipe. The outer wall of the heat-conducting pipe 6 can also be provided with spiral fins to improve heat transfer efficiency. Alternatively, the heat-conducting pipe 6 and heat exchanger can be omitted, and the heat storage section 2 and the heat source management section 3 can be arranged adjacent to each other, with the contact surface between the heat storage section 2 and the heat source management section 3 set as a heat-conducting surface, i.e., heat transfer is achieved through thermal conduction. Figure 1 As shown, the heat storage unit 2 is equipped with a heat exchange pipe 7. The input end of the heat exchange pipe 7 is connected to a cold water inlet pipe 11, and the output end of the heat exchange pipe 7 is connected to a hot water outlet pipe 12. Thus, when the user needs heat, the cold water inlet pipe 11 and the hot water outlet pipe 12 are opened; after the heat usage is completed, the cold water inlet pipe 11 is closed first, and then the hot water outlet pipe 12 is closed, completing the heat usage process. That is, the heat storage device 1 in this utility model can automatically control the heat output according to the amount of heat used by the user at the load end.

[0049] like Figure 1 As shown, both the heat storage unit 2 and the heat source management unit 3 of this invention are provided with a first insulation layer 10. The first insulation layer 10 reduces the heat dissipated from the heat storage unit 2 and the heat source management unit 3 to the outside, thereby enabling the energy of the heat storage unit 2 to meet the supply needs over a longer period. For example, the heat storage unit 2 collects excess heat in summer and supplies heat to the load end in winter when heat demand is high. The first insulation layer 10 is specifically made of a material with heat-insulating properties, which is existing technology and will not be exemplified here. Furthermore, an insulation layer deposit 8 is provided outside the first insulation layer 10. This deposit reduces the contact between the first insulation layer 10 and the outside environment, improving the heat insulation capacity of the first insulation layer 10 and reducing the heat dissipated from the heat storage unit 2 and the heat source management unit 3 to the outside.

[0050] like Figure 1As shown, the heat storage part 2 comprises a second heat storage chamber, and the heat source management part 3 comprises a first equalization chamber; wherein the cross-sectional areas of the second heat storage chamber and the first equalization chamber gradually decrease along the flow direction of heat, and the cross-sectional area of the second heat storage chamber close to one end of the first equalization chamber is smaller than that of the first equalization chamber close to the other end of the second heat storage chamber; at this time, the cross-sectional area of the second heat storage chamber is larger, which facilitates the rapid heat exchange between the second heat storage chamber and the load end.

[0051] Alternatively, the cross-sectional areas of the second heat storage chamber and the first equalization chamber gradually increase along the flow direction of heat, and the cross-sectional area of the second heat storage chamber close to one end of the first equalization chamber is larger than that of the first equalization chamber close to the other end of the second heat storage chamber. By reducing the cross-sectional area of heat flow, the rate of heat flow is improved, so that heat has the tendency to flow towards the second heat storage chamber, thereby reducing the problem that heat stagnates in the heat source management part 3, resulting in "dead zone", and part of the heat cannot be effectively transmitted to the heat storage part 2.

[0052] In addition, the heat storage part 2 comprises a first temperature zone, a second temperature zone and a third temperature zone with gradually decreasing temperatures; the output end of the heat source management part 3 is provided with a temperature sensor, and the output end of the heat source management part 3 is communicated with the first temperature zone, the second temperature zone and the third temperature zone through a first heat exchange pipe, a second heat exchange pipe and a third heat exchange pipe respectively, and the first heat exchange pipe, the second heat exchange pipe and the third heat exchange pipe are respectively provided with valves for controlling the on-off. The temperature of the heat output from the heat source management part 3 to the heat storage part 2 is detected by the temperature sensor, and according to the temperature interval where the temperature is located, the valve to be opened is determined, so that the heat of the corresponding grade is transmitted to the corresponding position of the heat storage part 2, so as to realize targeted use subsequently, and further improve the utilization efficiency of heat.

[0053] The collection of heat of different grades has various forms, for example, if the industrial waste heat of different grades is collected, a plurality of heat exchangers can be arranged in sequence along the flow direction of the flue gas, and heat of different grades is absorbed by different heat exchangers, and the closer to the boiler, the higher the grade of the heat absorbed. The heat temperature corresponding to the first temperature zone, the second temperature zone and the third temperature zone can be set in advance, for example, if the temperature sensor detects that the heat temperature output by the heat source management part 3 is greater than 80℃, the valve on the first heat exchanger pipe is opened, and the heat is input into the first temperature zone, if the temperature sensor detects that the heat temperature output by the heat source management part 3 is 60℃-80℃, the valve on the second heat exchanger pipe is opened, and the heat is input into the second temperature zone, if the temperature sensor detects that the heat temperature output by the heat source management part 3 is less than 60℃, the valve on the third heat exchanger pipe is opened, and the heat is input into the third temperature zone. The above temperature values are only examples for understanding the working process and are not necessarily actual values. The temperature sensor and the valve can be opened by an operator or by a controller. If the controller is used, the temperature sensor and the valve are connected to the controller, the controller receives the real-time value of the temperature sensor, compares the real-time value with the preset temperature interval, determines which temperature interval the heat belongs to, and then opens the corresponding valve to input the heat into the corresponding area of the heat storage part 2.

[0054] The heat in the first temperature zone can be used for heating, the heat in the second temperature zone can be used for boiling water, and the heat in the third temperature zone can be used for bathing. In this way, the utilization efficiency of heat is further improved by targeted use of heat of different grades. The first temperature zone, the second temperature zone and the third temperature zone are independently arranged, and a heat preservation layer or the like can be arranged outside the first temperature zone, the second temperature zone and the third temperature zone to prevent the heat temperatures in the first temperature zone, the second temperature zone and the third temperature zone from affecting each other.

[0055] It should be noted that when the heat storage part 2 includes the first temperature zone, the second temperature zone and the third temperature zone, the first temperature zone, the second temperature zone and the third temperature zone are actually equivalent to three independent heat storage parts 2. In this way, the heat in the first temperature zone, the second temperature zone and the third temperature zone is still in a uniform distribution state, and does not cause negative interference to the effective use of heat, but promotes the further effective use of heat.

[0056] Further, the heat source management part 3 includes a plurality of heat exchangers connected to the collection units of the heat source collection assembly respectively; and / or, the heat source management part 3 includes a second equalization chamber, and the second equalization chamber is provided with a stirring assembly or a flow guide assembly for mixing heat of different grades, and the flow guide assembly and the stirring assembly can also exist simultaneously. The heat of different grades, i.e. different temperatures, is mixed through the stirring assembly or the flow guide assembly, so that the heat can be more uniformly distributed in the heat storage part 2, thereby avoiding the problem of heat damage caused by local overheating or local overcooling of the heat storage part 2. The stirring assembly can specifically include stirring blades and a rotating motor for driving the stirring blades to rotate. The flow guide assembly can specifically include a flow guide plate arranged in the heat source management part 3, and the mixing of heat of different grades is realized by arranging the flow guide plate, for example, two opposite flow guide plates are arranged on both sides of the heat source management part 3, and the mixing is realized by the collision of heat of different grades.

[0057] However, the flow guide assembly and the stirring assembly are not the necessary structure of the heat source management part 3 in the utility model, and only through the warehouse of the heat source management part itself, the technical effect of integrating, equalizing and buffering heat of different types and different sources collected by the heat source collection assembly can be realized.

[0058] The heat source management part 3 and the heat storage part 2 are both provided with a heat insulation layer outside, and the heat insulation layer is filled with a heat exchange medium; a first heat exchange pipeline is arranged between the heat source collection assembly and the heat source management part 3, a second heat exchange pipeline is arranged between the heat storage part and the load end, and the first heat exchange pipeline and the second heat exchange pipeline are both sleeved with a second heat preservation layer outside; and the second heat preservation layer is in communication with the heat insulation layer.

[0059] The heat exchange medium in the heat insulation layer absorbs the heat emitted by the heat source management part 3 and the heat storage part 2 to the outside, and the heat is transported to the outside of the first heat exchange pipeline and the second heat exchange pipeline through a circulating pump and other equipment, that is, the heat emitted to the outside by the heat source management part and the heat storage part is insulated from the contact between the first heat exchange pipeline and the second heat exchange pipeline and the outside, the loss of the first heat exchange pipeline and the second heat exchange pipeline in the process of transporting heat is reduced, and therefore the cost loss of the heat storage device 1 is reduced.

[0060] As Figure 1As shown, the heat source management part 3 is provided with a water level gauge 17 and a second pressure gauge 18, the water level gauge 17 can detect the water level in the heat source management part 3 when the heat collection assembly transmits heat to the heat source management part 3 in the form of hot water or steam, so as to prevent the water level from being too low or too high, and the heat source management part 3 is also provided with a drain pipe 16, when the liquid level of the heat exchange medium such as water in the heat source management part 3 is high, the heat exchange medium can be discharged through the drain pipe 16. The heat storage part 2 is provided with a thermometer 13, a first pressure gauge 14 and a pressure relief valve, which can detect the state of the heat storage part 2 from multiple aspects, so as to ensure the stable operation of the heat storage part 2. The heat storage part 2 is also provided with a discharge valve 15, which can discharge the phase change heat storage material 9 in the heat storage part 2, and the pipeline where the discharge valve 15 is located is connected with the drain pipe 16 in the subsequent stage, which reduces the number of pipelines to be set and reduces the maintenance cost of the heat storage device 1 in the utility model.

[0061] It should be noted that there are multiple technical solutions in the utility model, but there is no opposite technical inspiration. For example, the cross-sectional area of the heat storage part and the heat source management part in the utility model changes gradually small and gradually large along the heat flow direction, but this is not the opposite situation, but two embodiments, and the specific application is determined according to the specific working condition.

[0062] The principle and implementation mode of the utility model are described by applying specific examples, and the above embodiment is only used to help understand the method and core idea of the utility model; meanwhile, for the general technical personnel in the field, according to the idea of the utility model, the specific implementation mode and application range will be changed. In conclusion, the content of the specification should not be understood as the limitation of the utility model.
