DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1 As shown, the present invention discloses a heat storage device 1, which includes: a heat source collection component, which includes a solar energy collection unit, an industrial waste heat collection unit, a geothermal energy collection unit and a wind energy collection unit; a heat storage unit 2, which is used to store the heat collected by the heat source collection component; a heat source management unit 3, which is respectively connected to the heat source collection component and the heat storage unit 2, and is used to transfer the heat collected by the heat source collection component to the heat storage unit 2; a load end, which is connected to the heat storage unit 2 and is used to consume the heat in the heat storage unit 2. The load end refers to a device or area that consumes heat, such as a residential area, an office building, etc.

[0036] The present invention collects excess heat in the heat-enriched area and the heat during the period of excess heat energy through a heat source collection component, and stores the heat collected by the heat source collection component in the heat storage part 2. When the load end needs heat, the heat storage part 2 supplies heat to the load end. This not only makes the excess heat in the heat-enriched area and the period of excess heat energy effectively utilized, but also solves the problem of mismatch between heat output and heat demand, avoids the waste of excess heat in the heat-enriched area and the period of excess heat energy, but also saves the consumption of additional energy when the load end uses heat, and reduces the cost of heat generation and heating. In addition, the present invention integrates, balances, and buffers the heat of different types and sources collected by the heat source collection component through the heat source management part 3, slows down the heat transfer speed, and makes the heat gradually and evenly transferred to the heat storage part 2. The heat in the heat storage part 2 is evenly distributed and maintained at a relatively stable level, which avoids the heat loss caused by local overheating or overcooling of the heat storage part 2, reduces the loss of heat in the storage process in the heat storage part 2, and further realizes the effective utilization of heat.

[0037] At the same time, by setting up the heat source management part 3, the heat of different types, different grades, i.e., different temperatures collected by the heat collection component can be mixed before entering the heat storage part 2, specifically in the process of being transferred from the heat source management part 3 to the heat storage part 2, 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, and reducing the probability of the heat storage part 2 being damaged due to overheating in a local area, thereby ensuring that the heat storage capacity of the heat storage part 2 is improved and the service life of the heat storage part 2 is extended.

[0038] In the present invention, the heat source management part 3 is connected to the heat storage part 2 and the heat collection component, and the heat storage part 2 is connected to the load end. This does not mean that the above structures must be connected. Being connected only means that heat can be transferred from the heat collection component to the heat source management part 3, from the heat source management part 3 to the heat storage part 2, and then from the heat storage part 2 to the load end. Whether it needs to be connected depends on the working conditions. 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 component, and between the heat storage part 2 and the load end has many forms. A heat exchanger can be set between the two corresponding structures, or the two corresponding structures can be set adjacent to each other and heat transfer can be achieved by setting a heat conductive surface; or other structures that can achieve heat transfer can also be used.

[0039] The heat source collection component in the present invention 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 component does not only include the above-mentioned types of collection units, and other heat sources with excess such as tidal energy can be equipped with corresponding collection units.

[0040] It should be noted that although the present invention 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 refers to collecting heat generated by solar energy, and heat exists in many forms, such as steam generated by solar energy, such as Figure 1As shown, at this time, the solar energy collection unit includes a solar thermal accumulator 20, and the solar thermal accumulator 20 is a structure that can use solar energy to generate steam or hot water. The solar thermal accumulator 20 is connected to the water pipe 19 in the heat source management part 3 through the water pipe 19. The solar thermal accumulator 20, the water pipe 19 and the water pipe 19 located in the heat source management part 3 form a circulation loop, that is, through the flow of steam or hot water in the heat source management part 3, the heat carried by it is transferred to the heat source management part 3. In order to further improve the heat transfer efficiency, two circulation loops can be set, one circulation loop is a water pipe 19 whose two ends are respectively connected to the input end and the output end of the solar thermal accumulator 20 and is partially located in the heat source management part 3, and the other circulation loop is the water pipe 19 completely located in the heat source management part 3. The heat generated by solar energy is transferred by heat exchange in the two circulation loops (the specific heat exchange structure can refer to the existing heat exchanger, which will not be repeated here).

[0041] The specific structure of other types of collection units may be a delivery pipeline or a delivery vehicle (the delivery vehicle collects heat from the heat source and then delivers the heat to the heat source management unit 3. The delivery vehicle also needs to establish a pipeline connection during the process of delivering heat to the heat source management unit 3). Figure 1 As shown, a distribution pipe 4 is provided in the heat source management part 3, one end of the distribution pipe 4 extends into the heat source management part 3, a plurality of nozzles 5 are evenly provided 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 used to be connected with a conveying vehicle or a conveying pipeline, that is, the heat collected by the industrial waste heat collection unit can be conveyed to the heat source management part 3 by means of a conveying pipeline + distribution pipe 4, or a conveying vehicle + distribution pipe 4. Among them, the heat source management part 3 may 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 collection component is transferred to the heat exchange medium, and the heat exchange medium then transfers the absorbed heat to the heat storage part 2.

[0042] Enterprises with industrial waste heat or surplus steam can store the excess heat in the heat storage unit 2 through a mobile heat storage vehicle or other transport vehicle or a transport pipeline, which ensures that the heat can be stored when the heat demand is small and the heat generation is surplus. In addition, the present invention collects and utilizes solar energy to generate heat through the solar energy collection component, which is equivalent to realizing indirect storage of solar energy, achieving the purpose of energy conservation and emission reduction, and reducing the dust and pollutant gas emissions caused by the single use of boilers to generate heat.

[0043] The structure of the heat storage part 2 in the present invention has various forms, such as Figure 1As shown, the heat storage unit 2 includes a first heat storage chamber, which is filled with a phase change heat storage material 9; at this time, after the heat source management unit 3 transfers heat to the first heat storage chamber, the heat is absorbed by the phase change heat storage material 9, which improves the heat storage capacity of the heat storage unit 2 through the phase change ability of the phase change heat storage material 9. And / or, the heat storage unit 2 includes a first heat exchanger, the input end of the first heat exchanger is connected to the heat source management unit 3, and the input end of the first heat exchanger is connected to 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 tube type, etc.

[0044] The position of the heat source management part 3 in the present invention can be set in various forms. For example, the heat source management part 3 can be set below the heat storage part 2; this allows the heat in the heat source management part 3 to be directly transferred upward to the heat storage part 2, so that the heat can be distributed more evenly in the heat storage part 2, avoiding the problem of uneven heat distribution in the heat storage part 2 and the inability to continuously and stably output uniform heat, thereby improving the heating capacity of the heat storage device 1 in the present invention; if the heat source management part 3 is set above the heat storage part 2, the heat will tend to dissipate upward, resulting in a "short circuit" phenomenon in which the upper temperature of the heat storage part 2 is too high and the lower temperature is insufficient, thereby reducing the overall heat storage effect of the heat storage part 2.

[0045] Alternatively, the heat source management unit 3 may not be arranged below the heat storage unit 2, but may be arranged outside the heat storage unit 2. The heat source management unit 3 is arranged around the outside of the heat storage unit 2. In this case, since a circle of heat source management units 3 is arranged outside the heat storage unit 2, the contact area between the heat source management unit 3 and the heat source collection component is increased, and the rate of heat transfer from the heat source collection component to the heat source management unit 3 is increased, and the problem of most of the heat being dissipated to the outside during the transfer process due to the slow heat transfer rate is avoided as much as possible. However, it should be noted that when a circle of heat source management units 3 is arranged outside the heat storage unit 2, the heat exchange pipe (or heat transfer pipe) between the heat storage unit 2 and the load end needs to avoid the setting of the heat source management unit 3. For example, the heat exchange pipe between the heat storage unit 2 and the load end is arranged above or below the heat source management unit 3, so as to ensure that the functions of the heat storage unit 2 and the heat source management unit 3 can be smoothly realized.

[0046] The arrangement of the heat source management unit 3 is not limited to the above-mentioned arrangement, and other distribution arrangements that do not hinder the normal functioning of the heat storage device 1 are also possible.

[0047] The heat storage part 2 and the heat source management part 3 in the present invention can be arranged underground, which reduces the ground area occupied by the heat storage device 1, so that other equipment can be arranged in the ground area of ​​the heat storage device 1, saving land resources; and / or, the heat storage part 2 and the heat source management part 3 are arranged close to the heat-intensive area, that is, the load end with large heat demand, which shortens the distance between the heat storage part 2 and the load end with large heat demand, reduces the large number of pipelines required for long distances, and reduces the heating cost of the heat storage device 1 in the present invention.

[0048] In the present invention, the 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 that can achieve heat transfer, such as Figure 1 As shown, a heat pipe 6 is provided in the heat source management part 3, a part of the heat pipe 6 is located in the heat source management part 3, and another part of the heat pipe 6 is located in the heat storage part 2. After the heat pipe 6 absorbs heat from the heat source management part 3, the part located in the heat storage part 2 transfers the heat to the heat storage part 2; the heat pipe 6 can be a T-shaped heat pipe, and the outer wall of the heat pipe 6 can also be provided with spiral fins for improving the heat transfer efficiency. Furthermore, the heat pipe 6 and the heat exchanger can be omitted, and the heat storage part 2 and the heat source management part 3 can be arranged adjacent to each other, and the contact surface between the heat storage part 2 and the heat source management part 3 can be set as a heat conduction surface, that is, heat transfer is achieved through heat conduction. Figure 1 As shown, a heat exchange tube 7 is provided in the heat storage part 2, and the input end of the heat exchange tube 7 is connected to a cold water inlet pipe 11, and the output end of the heat exchange tube 7 is connected to a hot water outlet pipe 12. In this way, when the user end needs to use heat, the cold water inlet pipe 11 and the hot water outlet pipe 12 are opened; after the heat is used, the cold water inlet pipe 11 is closed first, and then the hot water outlet pipe 12 is closed to complete the heat use process. That is, the heat storage device 1 in the present invention can automatically control the heat output according to the load end, that is, the amount of heat used by the user.

[0049] like Figure 1 As shown, the heat storage part 2 and the heat source management part 3 of the present invention are both provided with a first insulation layer 10; the first insulation layer 10 reduces the heat dissipated from the heat storage part 2 and the heat source management part 3 to the outside, so that the energy of the heat storage part 2 can meet the supply of a larger time span. For example, the heat storage part 2 collects excess heat in the summer and supplies heat to the load end in the winter when the heat demand is large. The first insulation layer 10 is specifically made of a material with insulation performance. The material with insulation performance is a prior art and will not be described here. In addition, an insulation layer deposit 8 is also provided outside the first insulation layer 10. The deposit reduces the contact between the first insulation layer 10 and the outside, thereby improving the insulation capacity of the first insulation layer 10 and reducing the heat dissipated from the heat storage part 2 and the heat source management part 3 to the outside.

[0050] like Figure 1As shown, the heat storage part 2 includes a second heat storage chamber, and the heat source management part 3 includes a first equalizing chamber; wherein, the cross-sectional areas of the second heat storage chamber and the first equalizing 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 equalizing chamber is smaller than the cross-sectional area of ​​the first equalizing chamber close to one end of the second heat storage chamber; at this time, the cross-sectional area of ​​the second heat storage chamber is larger, which facilitates 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 equalizing chamber gradually increase along the heat flow direction, and the cross-sectional area of ​​the second heat storage chamber near the first equalizing chamber is larger than the cross-sectional area of ​​the first equalizing chamber near the second heat storage chamber. By reducing the cross-sectional area of ​​heat flow and increasing the heat flow rate, the heat tends to flow toward the second heat storage chamber, thereby reducing the problem of heat stagnation in the heat source management unit 3, generating a "dead zone", and part of the heat cannot be effectively transferred to the heat storage unit 2.

[0052] In addition, the heat storage part 2 in the present invention includes a first temperature zone, a second temperature zone and a third temperature zone with gradually decreasing temperatures; a temperature sensor is provided at the output end of the heat source management part 3, and the output end of the heat source management part 3 is respectively connected to the first temperature zone, the second temperature zone and the third temperature zone through the first heat exchange tube, the second heat exchange tube and the third heat exchange tube, and valves for controlling on and off are respectively provided on the first heat exchange tube, the second heat exchange tube and the third heat exchange tube. 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 the valve to be opened is determined according to the temperature range in which the temperature is located, so that the heat of the corresponding grade is transferred to the corresponding position of the heat storage part 2, so as to realize targeted use later, and further improve the utilization efficiency of the heat.

[0053] Among them, the collection of heat of different grades has various forms. For example, if industrial waste heat of different grades is collected, multi-stage heat exchangers can be arranged in sequence along the flow direction of the flue gas, and different grades of heat are absorbed by different heat exchangers. The heat absorbed by the heat exchanger closer to the boiler is the heat of higher grade. And the heat temperatures corresponding to the first temperature zone, the second temperature zone, and the third temperature zone can be pre-set. For example, if the temperature sensor detects that the temperature of the heat output by the heat source management unit 3 is greater than 80°C, the valve on the first heat exchange tube is opened to input the heat into the first temperature zone. If the temperature sensor detects that the temperature of the heat output by the heat source management unit 3 is 60°C to 80°C, the valve on the second heat exchange tube is opened to input the heat into the second temperature zone. If the temperature sensor detects that the temperature of the heat output by the heat source management unit 3 is less than 60°C, the valve on the third heat exchange tube is opened to input the heat into the third temperature zone. The above temperature values ​​are only examples for the convenience of understanding the working process and are not necessarily actual values. The temperature sensor's indication is observed and the valve is opened. This can be done by an operator or by a controller. If it is done by a controller, the temperature sensor and the valve are connected to the controller signal. The controller receives the real-time value of the temperature sensor and compares the real-time value with the preset temperature range to determine which temperature range the heat belongs to, thereby opening the corresponding valve and transferring the heat to 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 heat utilization efficiency is further improved by making targeted use of heat of different qualities. The first temperature zone, the second temperature zone, and the third temperature zone are set independently of each other, and a structure such as a heat preservation layer can be set outside the first temperature zone, the second temperature zone, and the third temperature zone to prevent the heat temperature 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 a first temperature zone, a second temperature zone, and a 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 is still in a uniformly distributed state in the first temperature zone, the second temperature zone, and the third temperature zone, and will not cause negative interference to the effective use of heat. On the contrary, it promotes the further effective use of heat.

[0056] Furthermore, in the present invention, the heat source management part 3 includes a plurality of heat exchangers respectively connected to the collection units of the heat source collection assembly; and / or, the heat source management part 3 includes a second balancing chamber, in which a stirring assembly or a flow guide assembly for mixing heat of different grades is provided, and the flow guide assembly and the stirring assembly may also exist at the same time. The mixing of heat of different grades, i.e., different temperatures, is achieved by the stirring assembly or the flow guide assembly, so that the heat can be more evenly 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 may specifically include stirring blades, and a rotating motor that drives the stirring blades to rotate. The flow guide assembly may specifically include a flow guide plate arranged in the heat source management part 3, and the mixing of heat of different grades is achieved by setting 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 achieved by the hedging of heat of different grades.

[0057] However, the guide component and the stirring component are not necessary structures of the heat source management part 3 in the present invention. The technical effect of integrating, balancing and buffering the different types and sources of heat collected by the heat source collection component can be achieved only through the chamber of the heat source management part itself.

[0058] In the present invention, a heat insulation layer is provided outside the heat source management part 3 and the heat storage part 2, and a heat exchange medium is filled in the heat insulation layer; a first heat exchange pipe is provided between the heat source collection component and the heat source management part 3, and a second heat exchange pipe is provided between the heat storage part and the load end, and a second insulation layer is provided outside the first heat exchange pipe and the second heat exchange pipe; the second insulation layer is connected to the insulation layer.

[0059] The heat dissipated to the outside by the heat source management part 3 and the heat storage part 2 is absorbed by the heat exchange medium in the insulation layer, and the heat is transported to the outside of the first heat exchange pipe and the second heat exchange pipe through equipment such as a circulation pump. That is, the heat dissipated to the outside by the heat source management part and the heat storage part isolates the first heat exchange channel and the second heat exchange pipe from the outside, reducing the loss of the first heat exchange pipe and the second heat exchange pipe in the process of transporting heat, thereby reducing the cost loss of the heat storage device 1.

[0060] like Figure 1As shown, in the present invention, a water level gauge 17 and a second pressure gauge 18 are provided in the heat source management part 3. When the heat collection component transfers heat to the heat source management part 3 in the form of hot water or steam, the water level gauge 17 can detect the water level in the heat source management part 3 to prevent the water level from being too low or too high. In addition, a drain pipe 16 is provided in the heat source management part 3. When the liquid level of the heat exchange medium such as water in the heat source management part 3 is high, it can be discharged through the drain pipe 16. A thermometer 13, a first pressure gauge 14 and a pressure relief valve are provided in the heat storage part 2 to perform various detections on the state in the heat storage part 2 to ensure the stable operation of the heat storage part 2. A discharge valve 15 is also provided on the heat storage part 2 to discharge the internal phase change heat storage material 9, and the pipeline where the discharge valve 15 is located is subsequently connected in parallel with the drain pipe 16, which reduces the number of pipelines to be set and reduces the maintenance cost of the heat storage device 1 in the present invention.

[0061] It should be noted that there are multiple technical solutions in the present invention, but there is no situation that provides the opposite technical inspiration. For example, in the present invention, the cross-sectional area of ​​the heat storage part and the heat source management changes with the direction of heat flow, which can be either gradually reduced or gradually increased. However, these are not opposite situations, but belong to two embodiments. Which one is applied specifically depends on the specific working conditions.

[0062] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
