Description

Technical Field

[0001] This invention relates to the field of energy conversion and utilization in industrial production lines, specifically to a comprehensive energy application system for beer production. Background Technology

[0002] A typical industrial beer production process mainly includes saccharification, boiling, filtration, fermentation, and packaging. The bottle washing and pasteurization stages in saccharification, boiling, and packaging generally use low-pressure saturated steam for heating, becoming a significant source of heat consumption in beer production. Some stages in the beer production process require heating, while others require cooling, generating substantial amounts of low-temperature waste heat. However, this heat is not uniformly distributed, leading to the following problems in the production process:

[0003] 1. Currently, there are also simple, single-point applications in the industry that directly utilize the heat integration system of bottle washing machines and sterilizers in the packaging process. The heat of the alkaline solution in some alkaline tanks is higher than the actual required temperature. The heat is transferred to the sterilizer using intermediate circulating water. This system is simple in composition, has limited utilization time, and is greatly affected by the temperature changes of the alkaline solution. The utilization rate of the integrated system is not very high. Moreover, this energy transfer and utilization is limited to point-to-point processes and lacks comprehensive adjustment and adaptability.

[0004] 2. Currently, some waste heat utilization methods in the industry, such as the utilization of secondary steam condensation heat from boiling pots, can only achieve the transfer of high-grade energy to low-grade energy. They do not adopt the means of improving quality and raising temperature, and there are few points of heat utilization, resulting in insufficient heat utilization efficiency. In fact, a lot of low-grade heat energy cannot be utilized and is directly emitted into the environment, causing waste.

[0005] 3. Currently, some waste heat utilization methods in the industry, such as the high-temperature heat during the pre-cooling of hot wort, cannot provide enough heat-releasing hotspots to absorb within the short time of pre-cooling due to time constraints. Spatially, the saccharification process and the packaging process are far apart, and there are asynchronous and intermittent processes, making it difficult to achieve nearby utilization in terms of space and lacking energy interconnection channels.

[0006] 4. Currently, the industry conventionally designs refrigeration and steam systems to be independent of each other. Due to the limitations of traditional technology, combined cooling and heating cannot be achieved. Furthermore, cooling and heating also have temporal and spatial differences depending on production arrangements, making it impossible to achieve consistent temporal and spatial matching.

[0007] 5. Due to industry inertia, energy below 35°C, such as cooling tower systems in factories, is directly discharged and not considered to have any utilization value.

[0008] In summary, as described above, the common characteristics of these numerous low-temperature waste heat sources are low temperature quality, small total heat output per unit, dispersed distribution throughout the plant's process lines, intermittent operation following the main process, lack of continuity, and large time spans. Furthermore, the heat source quality differs from the usable temperature required by the main process by ≥50℃, making it unusable for direct application in the main production process. These are all low-temperature waste heat that cannot be directly utilized, and further, the need for tap water for cooling increases the company's water consumption. Additionally, the independent operation of refrigeration and heating systems in the process, failing to form a combined cooling and heating system, leads to energy losses. Limited by time and space, the process cannot directly transfer effective energy to other energy-consuming points within the process, resulting in energy waste.

[0009] In addition, fluid media such as water or steam are often stored in storage tanks during production (e.g., Figure 12 This allows for the extraction of the fluid medium when needed. Within the energy storage tank, the fluid medium stratifies due to temperature differences. For example, water at different temperatures has different densities. Inside the tank, the less dense, higher-temperature water is buoyed up and lies in the upper layer, while the denser, lower-temperature water (here, "high-temperature water" and "low-temperature water" are relative terms for the temperature difference) lies in the lower layer, forming a temperature transition zone (i.e., a thermocline). The thickness of the thermocline affects energy storage. Specifically, a thicker thermocline reduces the energy storage capacity of the tank, while a thinner thermocline increases it. Therefore, reducing the thickness of the thermocline is a current challenge. Summary of the Invention

[0010] This invention provides an integrated energy application system for beer production. This invention combines the operation of refrigeration and heating systems in the process to form a combined cooling and heating system to avoid energy loss.

[0011] The technical solutions to the above technical problems are as follows:

[0012] The integrated energy application system for beer production includes a first main pipeline, a second main pipeline, a fourth main pipeline, a sixth main pipeline, a seventh main pipeline, a first heat pump unit, a second heat pump unit, a power heat conversion unit, and a saccharification heat conversion unit.

[0013] The first heat pump unit is connected to the first main pipeline, the second main pipeline, the fourth main pipeline, and the sixth main pipeline, respectively; the second heat pump unit is connected to the fourth main pipeline, the sixth main pipeline, and the seventh main pipeline, respectively.

[0014] The power heat conversion unit is connected to the first main pipeline, the second main pipeline, the sixth main pipeline, and the seventh main pipeline, respectively; the saccharification heat conversion unit is connected to the fourth main pipeline and the sixth main pipeline, respectively.

[0015] The first heat pump unit recovers the low-temperature waste heat from the power heat conversion unit as the heat source of the unit, and produces a medium-temperature fluid medium which is output to the sixth main pipeline; the second heat pump unit recovers the waste heat from the saccharification heat conversion unit as the heat source of the unit, and produces a first medium-high temperature fluid medium which is output to the seventh main pipeline.

[0016] The system structure of the present invention has the following characteristics:

[0017] 1. Low-grade energy is supplied to industrial-grade high-temperature heat pumps as low-temperature heat sources. The industrial-grade high-temperature heat pumps use a small amount of input high-grade energy to transfer low-grade energy to high-grade energy and output high-grade heat energy to the outside, realizing energy recovery, transfer, quality improvement, heating and reuse.

[0018] 2. The high-grade heat energy transferred and output by the system can be directly released to the cold-end fluid of the energy-consuming process point, raising its temperature to the target required temperature. The cold-end fluid then transforms into a hot-end fluid, which is transported to the process point by a circulating power conveying device. The hot-end fluid releases heat to the energy-consuming process point, and the cooled cold-end fluid returns to the heat release side of the industrial-grade high-temperature heat pump to absorb heat, thus realizing the application of energy in this cycle.

[0019] 3. The high-grade heat energy transferred out by the system can be simultaneously released to the heat recovery cold-side medium of the energy storage and release system, raising its temperature to the target required temperature. The heat recovery cold-side medium is then transformed into a hot-side medium and returned to the energy storage and release system via a circulating power conveyor. The heat recovery hot-side medium stores heat in the energy storage and release system, thereby regulating the energy imbalance.

[0020] The present invention has the following advantages:

[0021] 1. To replace and change the current energy consumption situation in the beer industry, which relies on steam heating from fossil fuels and cooling from ammonia refrigeration units, and to solve the problem of independent and non-compensatory energy supply for cold and heat in beer production.

[0022] 2. Improve energy efficiency in beer production and reduce the high levels of heat consumption and refrigeration power consumption in beer production.

[0023] 3. Improve the overall energy utilization rate of beer production plants, reduce energy consumption by 20MJ per 100 liters of beer, and help the beer industry achieve the goal of "energy saving, consumption reduction, zero carbon and green".

[0024] 4. The rational and effective use of low-grade heat energy and the realization of efficient energy transfer to achieve the goal of improving quality and raising temperature is one of the important ways to improve energy utilization efficiency and save production costs.

[0025] 5. Reasonably and effectively recovering low-grade heat energy and achieving energy regulation in time and space, so as to consolidate scattered energy, smooth peaks and fill valleys, and utilize energy in stages, is one of the important ways to improve energy utilization efficiency and save production costs.

[0026] 6. The present invention recovers waste heat from various processes, overcoming time and space limitations, realizing energy transfer, storage, and energy transformation for quality improvement and temperature increase, which can be accessed anytime and anywhere and ultimately returned to the process for reuse.

[0039] In this embodiment, the fluid medium refers to a liquid heat-conducting medium, which can be an oil-based or water-based heat-conducting medium. In this embodiment, water is preferred as the fluid medium.

[0040] like Figure 1As shown, the integrated energy application system for beer production of the present invention includes a first main pipeline G1, a second main pipeline G2, a third main pipeline G3, a fourth main pipeline G4, a fifth main pipeline G5, a sixth main pipeline G6, a seventh main pipeline G7, a first heat pump unit Y1, a second heat pump unit Y2, a third heat pump unit Y3, a power heat conversion unit A, a saccharification heat conversion unit B, and a packaging and sterilization heat conversion unit C. The following is a detailed description of each part and the relationships between them:

[0041] like Figures 1 to 3 The first heat pump unit Y1 recovers the low-temperature waste heat of the power heat conversion unit A as the heat source of the unit, and produces the first medium-high temperature fluid medium which is output to the seventh main pipeline G7.

[0042] like Figures 1 to 3 The first heat pump unit Y1 is connected to the first main pipeline G1, the second main pipeline G2, the fourth main pipeline G4, and the sixth main pipeline G6. The first heat pump unit Y1 uses multiple heat pumps connected in series, and uses a variable frequency pump, flow meter, thermometer, and pressure gauge to control the temperature of the fluid medium at the output end. Two heat pumps can be connected in series. Therefore, the first heat pump unit Y1 has an evaporator-side output terminal Z11, an evaporator-side input terminal Z12, a condenser-side output terminal L11, and a condenser-side input terminal L12. The evaporator-side output terminal Z11 of the first heat pump unit Y1 is connected to the first main pipeline G1; the evaporator-side input terminal Z12 of the first heat pump unit Y1 is connected to the second main pipeline G2; the condenser-side output terminal L11 of the first heat pump unit Y1 is connected to the sixth main pipeline G6; and the condenser-side input terminal L12 of the first heat pump unit Y1 is connected to the fourth main pipeline G4.

[0043] like Figures 1 to 3 The first heat pump unit Y1 outputs a low-temperature fluid medium from its evaporator-side output terminal Z11, which enters the first main pipe G1. Within the first main pipe G1, the low-temperature fluid medium heats up to a first medium-low temperature fluid medium after flowing through the power heat conversion unit A. This first medium-low temperature fluid medium then flows along the second main pipe G2. The temperature of the low-temperature fluid medium output from the evaporator-side output terminal Z11 of the first heat pump unit Y1 is 0-3℃. The first medium-low temperature fluid medium is obtained from the evaporator-side input terminal Z12 of the first heat pump unit Y1 from the second main pipe G2, and its temperature is 18-22℃. Therefore, the temperature of the low-temperature fluid medium flowing along the first main pipe G2 is 0-3℃, and the temperature of the first medium-low temperature fluid medium flowing along the second main pipe G2 is 18-22℃.

[0044] like Figures 1 to 3The first heat pump unit Y1 outputs a medium-temperature fluid medium from its condenser-side outlet L11, which enters the sixth main pipe G6. The medium-temperature fluid medium flows along the sixth main pipe G6. The temperature of the medium-temperature fluid medium output from the condenser-side outlet L11 of the first heat pump unit Y1 is 58-62℃. The first heat pump unit Y1 obtains a second medium-low temperature fluid medium from the fourth main pipe G4, with a temperature of 28-32℃. Therefore, the temperature of the second medium-low temperature fluid medium flowing along the fourth main pipe G4 is 28-32℃.

[0045] like Figures 1 to 3 In this embodiment, the temperature of the low-temperature fluid medium is preferably 0°C, the temperature of the first medium-low temperature fluid medium is preferably 20°C, the temperature of the medium-temperature fluid medium is preferably 60°C, and the temperature of the second medium-low temperature fluid medium is preferably 30°C.

[0046] like Figures 1 to 3 The power heat conversion unit A is connected to the first main pipe G1, the second main pipe G2, the sixth main pipe G6, and the seventh main pipe G7 respectively.

[0047] like Figures 1 to 3 In this embodiment, the power heat conversion unit A includes a wort cooling heat exchange unit A1. The wort cooling heat exchange unit A1 includes a plate heat exchanger, an electric valve, a variable frequency pump, a temperature sensor, and a pressure sensor. The connections of these components are conventional and will not be described in detail here. One side of the wort cooling heat exchange unit A1 is connected to the first main pipe G1 and the second main pipe G2, and the other side of the wort cooling heat exchange unit A1 is used to connect to the wort conveying pipe P1.

[0048] like Figures 1 to 3 The first heat pump unit Y1 outputs a low-temperature fluid medium that flows through the first main pipe G1 to the wort cooling heat exchange unit A1, where it exchanges heat with the wort flowing through the wort cooling heat exchange unit A1, causing the temperature of the wort to decrease. The temperature of the low-temperature fluid medium then increases, becoming the first medium-low temperature fluid medium, and flows along the second main pipe G2.

[0049] like Figures 1 to 3 The low-temperature fluid medium output by the first heat pump unit Y1 is a fluid medium at 0°C, while the temperature of wort is usually around 30°C. Therefore, after heat exchange through the hot wort cooling heat exchange unit A1, the low-temperature fluid medium is heated to a temperature of 20°C, which is the temperature of the first medium-low temperature fluid medium. Since the first medium-low temperature fluid medium is obtained from the second main pipe G2 by the evaporation side input terminal Z12 of the first heat pump unit Y1, the 20°C first medium-low temperature fluid medium returns to the evaporation side of the first heat pump unit Y1 through the evaporation side input terminal Z12 of the first heat pump unit Y1.

[0050] like Figures 1 to 3The power heat conversion unit A also includes a deoxygenated water heating heat exchange unit A2. The deoxygenated water heating heat exchange unit A2 includes a plate heat exchanger, an electric valve, a variable frequency pump, a temperature sensor, and a pressure sensor. The connections between these components are conventional and will not be described in detail here. One side of the deoxygenated water heating heat exchange unit A2 is connected to the seventh main pipeline G7 and the sixth main pipeline G6, while the other side is used to connect to the deoxygenated water delivery pipeline P2.

[0051] like Figures 1 to 3 The first medium-high temperature fluid medium in the seventh main pipe G7 flows into the deoxygenated water heating heat exchange unit A2 and exchanges heat with the deoxygenated water flowing through the unit. The temperature of the first medium-high temperature fluid medium decreases, becoming a medium temperature fluid medium, and flows along the sixth main pipe G6. The temperature of the deoxygenated water increases, reducing its oxygen content. The deoxygenated water, after being cooled, is then used to mix with the cooled wort. Tap water can be used as the raw material for the deoxygenated water. Since the deoxygenated water needs to be mixed into the wort to dilute its concentration, the purpose of raising its temperature is to reduce the oxygen content in the water.

[0052] like Figures 1 to 3 Since the first medium-high temperature fluid medium flows along the seventh main pipe G7, and the temperature of the first medium-high temperature fluid medium is preferably 80℃, the temperature of the deoxygenated water can rise to 60℃ after heat exchange, thereby reducing the oxygen content. Since the temperature of the wort after cooling is 10℃, the temperature of the deoxygenated water after deoxygenation needs to be lowered before it can be mixed with the wort to dilute the concentration of the wort.

[0053] like Figure 1 , Figures 4 to 7 The second heat pump unit Y2 recovers the waste heat from the saccharification heat conversion unit B as the heat source for the unit, and produces the first medium-high temperature fluid medium which is output to the seventh main pipeline G7.

[0054] like Figure 1 , Figures 3 to 7 The second heat pump unit Y2 is connected to the fourth main pipe G4, the sixth main pipe G6, and the seventh main pipe G7, respectively. The second heat pump unit Y2 uses multiple heat pumps connected in series, and uses a variable frequency pump, flow meter, thermometer, and pressure gauge to control the temperature of the fluid medium at the output end. In this embodiment, two heat pumps are preferentially connected in series. Therefore, the second heat pump unit Y2 has an evaporator-side output terminal Z13, an evaporator-side input terminal Z14, a condenser-side output terminal L13, and a condenser-side input terminal L14. The evaporator-side output terminal Z13 of the second heat pump unit Y2 is connected to the fourth main pipe G4, the evaporator-side input terminal Z14 is connected to the sixth main pipe G6, the condenser-side output terminal L13 is connected to the seventh main pipe G7, and the condenser-side input terminal L14 is connected to the sixth main pipe G6.

[0055] like Figure 1 , Figures 3 to 7 The second heat pump unit Y2 outputs a second medium-low temperature fluid medium from the evaporator side output terminal Z13 and enters the fourth main pipe G4. The second medium-low temperature fluid medium in the fourth main pipe G4 is heated to a medium temperature fluid medium after flowing through the saccharification heat conversion unit B and / or the packaging sterilization heat conversion unit C. The medium temperature fluid medium flows along the sixth main pipe G6. The second heat pump unit Y2 obtains the medium temperature fluid medium from the sixth main pipe G6 as the heat source of the unit.

[0056] like Figure 1 , Figures 3 to 7 The second heat pump unit Y2 outputs a second medium-low temperature fluid medium at 28-32°C from its evaporator side output terminal Z13. Therefore, the temperature of the second medium-low temperature fluid medium flowing along the fourth main pipe G4 is 28-32°C. In this embodiment, the temperature of the second medium-low temperature fluid medium is preferably 30°C. The second heat pump unit Y2 outputs a first medium-high temperature fluid medium at 78-82°C from its condenser side output terminal L13. This first medium-high temperature fluid medium flows along the seventh main pipe G7. In this embodiment, the temperature of the first medium-high temperature fluid medium is preferably 80°C. The second heat pump unit Y2 receives a medium-temperature fluid medium at 58-62°C from its evaporator side input terminal Z14 and its condenser side input terminal L14.

[0057] like Figure 1 , Figures 4 to 7 The third heat pump unit Y3 uses the first medium-high temperature fluid medium flowing through the seventh main pipe G7 as the heat source of the unit, and outputs the high temperature fluid medium to the third main pipe G3.

[0058] like Figure 1 , Figures 4 to 7 The third heat pump unit Y3 is connected to the third main pipeline G3, the fifth main pipeline G5, the sixth main pipeline G6, and the seventh main pipeline G7. The third heat pump unit Y3 uses multiple heat pumps connected in series, and uses a variable frequency pump, flow meter, thermometer, and pressure gauge to control the temperature of the fluid medium at the output end. In this embodiment, the third heat pump unit Y3 preferably uses two heat pumps connected in series. Therefore, the third heat pump unit Y3 has an evaporator-side output terminal Z15, an evaporator-side input terminal Z16, a condenser-side input terminal L15, and a condenser-side output terminal L16. The evaporator-side output terminal Z15 of the third heat pump unit Y3 is connected to the sixth main pipeline G6, the evaporator-side input terminal Z16 is connected to the seventh main pipeline G7, the condenser-side output terminal L16 is connected to the third main pipeline G3, and the condenser-side input terminal L15 is connected to the fifth main pipeline G5.

[0059] like Figure 1 , Figures 4 to 7The third heat pump unit Y3 obtains a first medium-high temperature fluid medium from the seventh main pipe G7 at its evaporator side input terminal Z16. The third heat pump unit Y3 outputs a medium-temperature fluid medium into the sixth main pipe G6 at its evaporator side output terminal Z15. The temperature of the first medium-high temperature fluid medium obtained by the third heat pump unit Y3 from the seventh main pipe G7 at its evaporator side input terminal Z16 is 78-82℃. The temperature of the first medium-high temperature fluid medium obtained by the third heat pump unit Y3 from the seventh main pipe G7 at its evaporator side input terminal Z16 is preferably 80℃. The temperature of the medium-temperature fluid medium output by the third heat pump unit Y3 from its evaporator side output terminal Z15 is 58-62℃. The temperature of the medium-temperature fluid medium output by the third heat pump unit Y3 from its evaporator side output terminal Z15 is preferably 60℃.

[0060] like Figure 1 , Figures 4 to 7 After the high-temperature fluid medium output from the condenser side output terminal L16 of the third heat pump unit Y3 enters the third main pipe G3, the high-temperature fluid medium in the third main pipe G3 is cooled down to the second medium-high temperature fluid medium after flowing through the saccharification heat conversion unit B and the packaging sterilization heat conversion unit C. The second medium-high temperature fluid medium flows along the fifth main pipe G5, and the condenser side input terminal L15 of the third heat pump unit Y3 obtains the second medium-high temperature fluid medium from the fifth main pipe G5.

[0061] like Figure 1 , Figures 4 to 7 The temperature of the high-temperature fluid medium output from the condenser side output terminal L16 of the third heat pump unit Y3 is 90-100℃, the temperature of the high-temperature fluid medium output from the condenser side output terminal L16 of the third heat pump unit Y3 is 95℃, the temperature of the second medium-high temperature fluid medium obtained from the fifth main pipe G5 at the condenser side input terminal L15 of the third heat pump unit Y3 is 80-88℃, and the temperature of the second medium-high temperature fluid medium obtained from the fifth main pipe G5 at the condenser side input terminal L15 of the third heat pump unit Y3 is preferably 87℃.

[0062] like Figure 1 , Figures 4 to 7 The saccharification heat conversion unit B is connected to the third main pipe G3, the fourth main pipe G4, the fifth main pipe G5, and the sixth main pipe G6, respectively. The packaging sterilization heat conversion unit C is connected to the third main pipe G3, the fourth main pipe G4, the fifth main pipe G5, the sixth main pipe G6, and the seventh main pipe G7, respectively.

[0063] like Figure 1 , Figures 4 to 7The saccharification heat conversion unit B includes a boiling heat exchange unit B1, which comprises a plate heat exchanger, an electric valve, a variable frequency pump, a temperature sensor, and a pressure sensor. The connections between these components are conventional and will not be described in detail here. One side of the boiling heat exchange unit B1 is connected to the fourth main pipe G4 and the sixth main pipe G6, while the other side is used to connect to the condensate delivery pipe P3. The second heat pump unit Y2 outputs a second medium-low temperature fluid medium that flows through the fourth main pipe G4 and then through the boiling heat exchange unit B1, recovering the heat from the boiling heat exchange unit B1. After the second medium-low temperature fluid medium is heated, it becomes a medium temperature fluid medium and flows along the sixth main pipe G6.

[0064] like Figure 1 , Figures 4 to 7 In actual production, the pulverized malt is first gelatinized, then water is added, and steam is used to boil the gelatinized mixture. During the boiling process, condensate is generated, which contains a large amount of heat. It is necessary to recover the heat generated in the condensate during the boiling process. Therefore, in this embodiment, the fourth main pipe G4 is connected to the boiling heat exchange unit B1. When the second low-temperature fluid medium (30°C) in the fourth main pipe G4 flows through the boiling heat exchange unit B, it will be heated to become a medium-temperature fluid medium. The medium-temperature fluid medium enters the sixth main pipe G6. Since the second heat pump unit Y2 obtains the medium-temperature fluid medium (60°C) from the sixth main pipe G6, the second heat pump unit Y2 recovers the waste heat in the saccharification heat conversion unit B as the heat source of the unit.

[0065] like Figure 1 , Figures 4 to 7 In this embodiment, the saccharification heat conversion unit B further includes a saccharification cleaning heat exchange unit B2. The saccharification cleaning heat exchange unit B2 includes a plate heat exchanger, an electric valve, a variable frequency pump, a temperature sensor, and a pressure sensor. The connections between these components are conventional and will not be described in detail here. One side of the saccharification cleaning heat exchange unit B2 is connected to the third main pipeline G3 and the fifth main pipeline G5, and the other side of the saccharification cleaning heat exchange unit B2 is used to connect to the saccharification cleaning water pipeline P4.

[0066] like Figure 1 , Figures 4 to 7In actual production, sugar is added during boiling, often resulting in the formation of adhering substances on the surface of the boiling boiler. After boiling, a high-temperature fluid medium is needed to clean the boiler. Therefore, the temperature of the saccharification cleaning water needs to be increased. In this embodiment, the high-temperature fluid medium output by the third heat pump unit Y3 flows through the third main pipe G3 and then through the saccharification cleaning heat exchange unit B2. After heat exchange, the temperature of the saccharification cleaning water flowing along the saccharification cleaning water pipe P4 increases, while the high-temperature fluid medium cools down to become a second medium-high temperature fluid medium and flows along the fifth main pipe G5. Since the temperature of the high-temperature fluid medium flowing along the third main pipe G3 is preferentially 95°C, after heat exchange with the saccharification cleaning water, the 95°C high-temperature fluid medium cools down to become a second medium-high temperature fluid medium at 87°C and flows along the fifth main pipe G5.

[0067] like Figure 1 , Figures 4 to 7 In actual production, steam is often generated on the production line. Since steam storage requires a certain space, in this embodiment, a portion of the heat energy of the steam is converted into a fluid medium. The specific implementation process is as follows: The saccharification heat conversion unit B also includes a steam heat exchange unit B3. The steam heat exchange unit B3 includes a plate heat exchanger, an electric valve, a frequency converter pump, a temperature sensor, and a pressure sensor. The connection relationship of these parts is conventional and will not be described in detail here.

[0068] like Figure 1 , Figures 4 to 7 One side of the steam heat exchange unit B3 is connected to the fourth main pipe G4 and the third main pipe G3, and the other side of the steam heat exchange unit B3 is used to connect to the steam pipe P3a. The second medium-low temperature fluid medium output by the second heat pump unit Y2 flows through the fourth main pipe G4 and then through the steam heat exchange unit B3. After heat exchange, the second medium-low temperature fluid medium is heated to become a high temperature fluid medium and then flows along the third main pipe G3.

[0069] like Figure 1 , Figures 4 to 7 Through the above structure, the heat in the steam can be converted into the second medium-low temperature fluid medium at 30°C, making the second medium-low temperature fluid medium into a high temperature fluid medium at 95°C. The high temperature fluid medium flows along the third main pipe G3 for use in cleaning the equipment in the saccharification heat conversion unit B, as well as for cleaning the equipment in the packaging sterilization heat conversion unit C and for heating the alkali solution.

[0070] like Figure 1 , Figures 4 to 7In the entire beer production process, multiple filtrations are involved. Since there are many deposits on these filtration devices, they need to be cleaned. The cleaning water needs to be at a certain temperature. For example, if the raw material for the cleaning water is tap water, the tap water needs to be heated before it can be used as cleaning water. Therefore, the saccharification heat conversion unit B also includes a filtration device cleaning heat exchange unit B4. One side of the filtration device cleaning heat exchange unit B4 is connected to the third main pipe G3 and the fifth main pipe G5, and the other side of the filtration device cleaning heat exchange unit B4 is used to connect to the filtration cleaning water pipe P5.

[0071] like Figure 1 , Figures 4 to 7 A high-temperature fluid medium at 95°C is used to exchange heat with the filtered cleaning water through the heat exchange unit B4 of the filtration equipment. After the heat exchange, the 95°C high-temperature fluid medium cools down to a second medium-high temperature fluid medium at 87°C, while the temperature of the filtered cleaning water rises to the required temperature, such as 60°C. The heat exchange unit B4 of the filtration equipment includes a plate heat exchanger, an electric valve, a variable frequency pump, a temperature sensor, and a pressure sensor. The connections between these components are conventional and will not be described in detail here.

[0072] like Figure 1 , Figures 4 to 7 The packaging sterilization heat exchange unit C includes a sterilization heat exchange unit C1 and a packaging heat exchange unit C2. Both sterilization heat exchange unit C1 and packaging heat exchange unit C2 include a plate heat exchanger, an electric valve, a frequency converter pump, a temperature sensor, and a pressure sensor. The connection relationship of these parts is conventional and will not be described in detail here.

[0073] like Figure 1 , Figures 4 to 7 After beer is bottled, it needs to be heated to a set temperature to kill some bacteria in the beer. This is usually done by immersing the bottle in pasteurizing water at the set temperature. Therefore, the pasteurizing water needs to be heated to a specific temperature. The raw material for pasteurizing water is generally tap water. This invention describes a method for heating tap water to create pasteurizing water as follows.

[0074] like Figure 1 , Figures 4 to 7 One side of the sterilization heat exchange unit C1 is connected to the seventh main pipe G7 and the sixth main pipe G6, and the other side of the sterilization heat exchange unit C1 is used to connect to the sterilization water pipe P6. The first medium-high temperature fluid medium in the seventh main pipe G7 flows through the sterilization heat exchange unit C1. After heat exchange, the first medium-high temperature fluid medium is cooled down and becomes a medium temperature fluid medium that flows along the sixth main pipe G6. The temperature of the sterilization water flowing along the sterilization water pipe P6 is increased.

[0075] like Figure 1 , Figures 4 to 7The temperature of the first medium-high temperature fluid medium flowing from the seventh main pipe G7 to the sterilization heat exchange unit C1 is preferably 80°C. After heat exchange, the 80°C first medium-high temperature fluid medium cools down to 60°C and flows back to the sixth main pipe G6 for use by other units. The temperature of the sterilization water rises to a specified temperature, such as 60°C.

[0076] like Figure 1 , Figures 4 to 7 After beer is bottled, the cap needs to be secured to the bottle to seal the beer. During cap installation, a vacuum pump is typically used to press the cap onto the bottle. Because the vacuum pump operates at a high frequency (on a production line), its temperature needs to be maintained within a suitable range. Therefore, cooling the vacuum pump is necessary. Liquid cooling can be used, so controlling the temperature of the coolant controls the temperature of the vacuum pump. The present invention provides a solution for controlling the coolant temperature as follows.

[0077] like Figure 1 , Figures 4 to 7 One side of the packaging heat exchange unit C2 is connected to the fourth main pipe G4 and the sixth main pipe G6. The other side of the packaging heat exchange unit C2 is used to connect to the vacuum pump cooling water pipe P7. The second medium-low temperature fluid medium in the fourth main pipe G4 flows through the packaging heat exchange unit C2. After heat exchange, the second medium-low temperature fluid medium is heated to become a medium temperature fluid medium and then flows along the sixth main pipe G6. The temperature of the cooling water flowing along the vacuum pump cooling water pipe P7 decreases.

[0078] like Figure 1 , Figures 4 to 7 The temperature of the second low-temperature fluid medium flowing from the fourth main pipe G4 to the packaging heat exchange unit C2 is preferably 30°C. After heat exchange with the coolant of the cooling vacuum pump through the packaging heat exchange unit C2, the 30°C second low-temperature fluid medium is heated to 60°C and flows back to the sixth main pipe G6 to recover the heat in the system for use by other units. The temperature of the coolant is stabilized within a specified range, such as 55-60°C.

[0079] like Figure 1 , Figures 4 to 7 Before bottling beer, the bottles need to be cleaned. Because lye has strong stain-removing properties, it is commonly used to clean beer bottles. The cleaning effect is even better when the lye is heated to a medium-high temperature. The lye is usually mixed with tap water first and then heated. The present invention provides a scheme for adjusting the temperature of the lye.

[0080] like Figure 1 , Figures 4 to 7The packaging sterilization heat exchange unit C also includes an alkali heat exchange unit C3 and a bottle washing alkali heat exchange unit C4. Both the alkali heat exchange unit C3 and the bottle washing alkali heat exchange unit C4 include a plate heat exchanger, an electric valve, a frequency converter pump, a temperature sensor, and a pressure sensor. The connection relationship of these parts is conventional and will not be described in detail here.

[0081] like Figure 1 , Figures 4 to 7 One side of the alkali heat exchange unit C3 is connected to the third main pipe G3 and the fifth main pipe G5, and the other side of the alkali heat exchange unit C3 is used to connect to the alkali pipe P8. The high-temperature fluid medium in the third main pipe G3 flows through the alkali heat exchange unit C3. After heat exchange, the high-temperature fluid medium is cooled down to become the second medium-high temperature fluid medium and then flows along the fifth main pipe G5. The temperature of the alkali flowing along the alkali pipe P8 increases.

[0082] like Figure 1 , Figures 4 to 7 The temperature of the high-temperature fluid medium flowing from the third main pipe G3 to the alkali heat exchange unit C3 is preferably 95°C. After heat exchange with the alkali liquid through the alkali heat exchange unit C3, the 95°C high-temperature fluid medium cools down to 87°C and flows back to the fifth main pipe G5 for use by other units. The temperature of the alkali liquid is stabilized within a specified range, such as 80°C.

[0083] like Figure 1 , Figures 4 to 7 The heated alkaline solution is used for bottle washing. After the alkaline solution cleans the bottles, the heat energy is recovered. The specific scheme is as follows.

[0084] like Figure 1 , Figures 4 to 7 One side of the bottle washing alkali heat exchange unit C4 is connected to the fourth main pipe G4 and the sixth main pipe G6, and the other side of the bottle washing alkali heat exchange unit C4 is used to connect to the bottle washing alkali pipe P9. The second medium-low temperature fluid medium in the fourth main pipe G4 flows through the bottle washing alkali heat exchange unit C4. After heat exchange, the second medium-low temperature fluid medium is heated to become a medium temperature fluid medium and then flows along the sixth main pipe G6. The temperature of the bottle washing alkali flowing along the bottle washing alkali pipe P9 decreases.

[0085] like Figure 1 , Figures 4 to 7 The temperature of the second low-temperature fluid medium flowing from the fourth main pipe G4 to the bottle washing alkali heat exchange unit C4 is preferably 30°C. After heat exchange with the bottle washing alkali in the bottle washing alkali heat exchange unit C4, the 30°C second low-temperature fluid medium is heated to 60°C medium-temperature fluid medium and flows back to the sixth main pipe G6 for use by other units. The temperature of the bottle washing alkali decreases, thereby recovering the heat energy in the bottle washing alkali.

[0086] like Figure 1 , Figures 4 to 7 The packaging sterilization heat conversion unit C also includes a hydrogen exhaust heat exchange unit C5, which includes a plate heat exchanger, an electric valve, a frequency converter pump, a temperature sensor, and a pressure sensor. The connection relationship of these parts is conventional and will not be described in detail here.

[0087] like Figure 1 , Figures 4 to 7 Since the main component of the alkaline solution is NaOH, hydrogen gas is generated during the cleaning of wine bottles using this solution. When the hydrogen concentration in the air is too high, an explosion can occur. Therefore, in actual production, the hydrogen-containing hot gas in the cleaning workshop is extracted and treated. Because the temperature of the alkaline solution is 80℃, the temperature of the hydrogen-containing hot gas in the cleaning workshop is also relatively high, typically around 70℃. Directly treating and releasing this gas would result in heat loss. The heat recovery scheme for the hydrogen-containing hot gas in this embodiment is as follows.

[0088] like Figure 1 , Figures 4 to 7 One side of the hydrogen exhaust heat exchange unit C5 is connected to the fourth main pipeline G4 and the sixth main pipeline G6. The other side of the hydrogen exhaust heat exchange unit C5 is used to connect to the gas conveying pipeline P10 for conveying hydrogen-containing hot gas. The second medium-low temperature fluid medium in the fourth main pipeline G4 flows through the hydrogen exhaust heat exchange unit C5. After heat exchange, the second medium-low temperature fluid medium is heated to become a medium temperature fluid medium and then flows along the sixth main pipeline G6. The temperature of the hydrogen-containing hot gas flowing along the hydrogen exhaust heat exchange unit C5 decreases.

[0089] like Figure 1 , Figures 4 to 7 The temperature of the second low-temperature fluid medium flowing from the fourth main pipe G4 to the hydrogen exhaust heat exchange unit C5 is preferably 30°C. After exchanging heat with the hydrogen-containing hot gas through the hydrogen exhaust heat exchange unit C5, the 30°C second low-temperature fluid medium is heated to 60°C and flows back to the sixth main pipe G6 for use by other units. The temperature of the hydrogen-containing hot gas decreases, thereby recovering the heat energy in the bottle washing alkali solution.

[0090] like Figure 1 , Figures 4 to 7 The packaging sterilization heat exchange unit C also includes an equipment rinsing heat exchange unit C6, which includes a plate heat exchanger, an electric valve, a frequency converter pump, a temperature sensor, and a pressure sensor. The connection relationship of these parts is conventional and will not be described in detail here.

[0091] like Figure 1 , Figures 4 to 7Similarly, within the entire packaging sterilization heat conversion unit C, the surfaces of bottle washing equipment and other items have many deposits, requiring cleaning with equipment cleaning water. However, the raw material for this cleaning water is generally tap water, which is at room temperature and has limited cleaning effectiveness. Therefore, the tap water is heated before being used to clean the equipment within the packaging sterilization heat conversion unit C. The specific solution is as follows.

[0092] like Figure 1 , Figures 4 to 7 One side of the equipment flushing heat exchange unit C6 is connected to the third main pipe G3 and the fifth main pipe G5, and the other side of the equipment flushing heat exchange unit C6 is used to connect to the equipment flushing water pipe P11. The high-temperature fluid medium in the third main pipe G3 flows through the equipment flushing heat exchange unit C6. After heat exchange, the high-temperature fluid medium is cooled down to become the second medium-high temperature fluid medium and then flows along the fifth main pipe G5. The temperature of the equipment flushing water flowing along the equipment flushing heat exchange unit C6 increases.

[0093] like Figure 1 , Figures 4 to 7 The temperature of the high-temperature fluid medium flowing from the third main pipe G3 to the equipment flushing heat exchange unit C6 is preferably 95°C. After heat exchange with the equipment cleaning water through the equipment flushing heat exchange unit C6, the 95°C high-temperature fluid medium cools down to 87°C and flows back to the fifth main pipe G5 for use by other units. The temperature of the equipment cleaning water is stabilized within a specified range, such as 80°C.

[0094] like Figure 1 and Figure 8 The system can store energy as needed and extract it directly from the storage point when required. This reduces the operating time of each heat pump unit, thereby lowering the system's energy consumption and reducing equipment operating costs. The integrated energy application system for beer production also includes a first energy storage tank D1, a first branch pipe G11, a second branch pipe G12, a first valve F1, and a second valve F2. The first energy storage tank D1 is connected to one end of the first branch pipe G11 and one end of the second branch pipe G12. The other end of the first branch pipe G11 is connected to the first main pipeline G1, and the other end of the second branch pipe G12 is connected to the second main pipeline G2. The first valve F1 is located on the first branch pipe G11, and the second valve F2 is located on the second branch pipe G12.

[0095] like Figure 1 and Figure 8 The first energy storage tank D1 is used to store a low-temperature fluid medium or a first medium-low temperature fluid medium. When the system needs it, the low-temperature fluid medium in the first energy storage tank D1 is output to the first main pipeline G1, or the first medium-low temperature fluid medium stored in the first energy storage tank D1 is output to the second main pipeline G2.

[0096] like Figure 1 and Figure 8 For example, after the first heat pump unit Y1 is started, the low-temperature fluid medium (0°C) output by the first heat pump unit Y1 enters the first main pipe G1. A portion of the low-temperature fluid medium can be transported to the first energy storage tank D1 through the first branch pipe G11. If the low-temperature fluid medium in the first main pipe G1 is insufficient, the low-temperature fluid medium in the first energy storage tank D1 can flow into the first main pipe G1.

[0097] like Figure 1 and Figure 8 When the first heat pump unit Y1 is in the off state, since both the input and output ends of the first heat pump unit Y1 are closed, to maintain system operation, the low-temperature fluid medium in the first energy storage tank D1 is output to the first main pipe G1 through the first branch pipe G11. The low-temperature fluid medium in the first main pipe G1 is heated to 20°C by heat exchange through the power heat conversion unit A and flows into the second main pipe G2. The 20°C first medium-low temperature fluid medium in the second main pipe G2 then flows back to the first energy storage tank D1 through the second branch pipe G12. In this way, the amount of 0°C low-temperature fluid medium decreases with use, while the amount of 20°C first medium-low temperature fluid medium gradually increases, and the temperature in the first energy storage tank D1 gradually rises to the first medium-low temperature, i.e., 20°C. Therefore, through the above structure, the first energy storage tank D1 stores either low-temperature fluid medium or first medium-low temperature fluid medium.

[0098] For the storage methods of the second low-temperature fluid medium and the medium-temperature fluid medium, the present invention designs the following scheme:

[0099] like Figure 1 and Figure 8 The integrated energy application system for beer production also includes a second energy storage tank D2, a third branch pipe G13, a fourth branch pipe G14, a third valve F3, and a fourth valve F4. The second energy storage tank D2 is connected to one end of the third branch pipe G13 and the fourth branch pipe G14 respectively. The other end of the third branch pipe G13 is connected to the fourth main pipe G4, and the other end of the fourth branch pipe G14 is connected to the sixth main pipe G6. The third valve F3 is installed on the third branch pipe G13, and the fourth valve F4 is installed on the fourth branch pipe G14.

[0100] like Figure 1 and Figure 8 The second storage tank D2 is used to store medium-temperature fluid medium or second medium-low temperature fluid medium. When the system needs it, the medium-temperature fluid medium stored in the second storage tank D2 is output to the sixth main pipeline G6, or the second medium-low temperature fluid medium stored in the second storage tank D2 is output to the fourth main pipeline G4.

[0101] like Figure 1and Figure 8 When the system is running, the second medium-low temperature fluid medium at 30°C is first stored in the second energy storage tank D2. As the amount of the second medium-low temperature fluid medium entering the second energy storage tank D2 increases, the water temperature of the second energy storage tank D2 gradually decreases to 30°C (the tank may originally contain a medium temperature fluid medium at 60°C. When the system is running, the medium temperature fluid medium at 60°C is gradually discharged into the sixth main pipeline G6 through the fourth branch pipe G14).

[0102] like Figure 1 and Figure 8 When each heat pump unit is shut down, since the heat pump units do not participate in system operation, the second low-temperature fluid medium in the second storage tank D2 is output to the fourth main pipe G4 through the third branch pipe G13. After heat exchange in the boiling heat exchange unit B1 and / or the packaging heat exchange unit C2 and / or the bottle washing alkali heat exchange unit C4 and / or the hydrogen removal heat exchange unit C5, it becomes a medium-temperature fluid medium at 60°C. This medium-temperature fluid medium enters the sixth main pipe G6, and then returns to the third storage tank D3 through the fourth branch pipe G14. As the amount of the second low-temperature fluid medium at 30°C decreases, the amount of the medium-temperature fluid medium at 60°C increases. Ultimately, the second storage tank D2 stores the medium-temperature fluid medium at 60°C. Therefore, when the heat pump units are running, the second storage tank D2 gradually stores the second low-temperature fluid medium at 30°C; when the heat pump units are shut down, the second storage tank D2 gradually stores the medium-temperature fluid medium at 60°C.

[0103] For the storage methods of the first high-temperature fluid medium and the medium-temperature fluid medium, the present invention designs the following scheme:

[0104] like Figure 1 and Figure 8 The integrated energy application system for beer production also includes a third energy storage tank D3, a fifth branch pipe G15, a sixth branch pipe G16, a fifth valve F5, and a sixth valve F6. The third energy storage tank D3 is connected to one end of both the fifth and sixth branch pipes G15 and G16. The other end of the fifth branch pipe G15 is connected to the sixth main pipe G6, and the other end of the sixth branch pipe G16 is connected to the seventh main pipe G7. The fifth valve F5 is located on the fifth branch pipe G15, and the sixth valve F6 is located on the sixth branch pipe G16. There can be one or more third energy storage tanks D3; when multiple are used, they are connected in series.

[0105] like Figure 1 and Figure 8 The third storage tank D3 is used to store the first medium-high temperature fluid medium or the medium temperature fluid medium. When the system needs it, the first medium-high temperature fluid medium stored in the third storage tank D3 is output to the seventh main pipeline G7, or the medium temperature fluid medium stored in the third storage tank D3 is output to the sixth main pipeline G6.

[0106] like Figure 1 and Figure 8 When the system is running, the first medium-high temperature fluid medium at 80°C is first stored in the third storage tank D3. As the amount of the first medium-high temperature fluid medium entering the third storage tank D3 increases, the water temperature in the third storage tank D3 gradually rises to 80°C (the tank may originally contain a medium temperature fluid medium at 60°C. When the system is running, the medium temperature fluid medium at 60°C is gradually discharged into the sixth main pipeline G6 through the fifth branch pipe G15).

[0107] like Figure 1 and Figure 8 When each heat pump unit is shut down, since the heat pump units do not participate in system operation, the first medium-high temperature fluid medium in the third energy storage tank D3 is output to the seventh main pipe G7 through the sixth branch pipe G16. After heat exchange by the deoxygenated water heating heat exchange unit A2 and / or sterilization heat exchange unit C1, it becomes a medium-temperature fluid medium at 60°C. This medium-temperature fluid medium enters the sixth main pipe G6 and then returns to the third energy storage tank D3 through the fifth branch pipe G15. As the amount of the first medium-high temperature fluid medium at 80°C decreases, the amount of the medium-temperature fluid medium at 60°C increases. Ultimately, the third energy storage tank D3 stores the medium-temperature fluid medium at 60°C. Therefore, when the heat pump units are running, the third energy storage tank D3 gradually stores the first medium-high temperature fluid medium at 80°C; when the heat pump units are shut down, the third energy storage tank D3 gradually stores the medium-temperature fluid medium at 60°C.

[0108] For the storage of high-temperature fluid media and the second type of high-temperature fluid media, the present invention designs the following scheme:

[0109] like Figure 1 and Figure 8 The integrated energy application system for beer production also includes a fourth energy storage tank D4, a seventh branch pipe G17, an eighth branch pipe G18, a seventh valve F7, and an eighth valve F8. The fourth energy storage tank D4 is connected to one end of both the seventh and eighth branch pipes G17 and G18. The other end of the seventh branch pipe G17 is connected to the fifth main pipeline G5, and the other end of the eighth branch pipe G18 is connected to the third main pipeline G3. The seventh valve F7 is installed on the seventh branch pipe G17, and the eighth valve F8 is installed on the eighth branch pipe G18. There can be one or more fourth energy storage tanks D4; when multiple are used, they are connected in series.

[0110] like Figure 1 and Figure 8 The fourth accumulator D4 is used to store high-temperature fluid medium or the second medium-high temperature fluid medium. When the system needs it, the high-temperature fluid medium stored in the fourth accumulator D4 is output to the third main pipeline G3, or the second medium-high temperature fluid medium stored in the fourth accumulator D4 is output to the sixth main pipeline G6.

[0111] like Figure 1 and Figure 8 When the system is running, the high-temperature fluid medium at 95°C is first stored in the fourth storage tank D4. As the amount of high-temperature fluid medium entering the fourth storage tank D4 increases, the water temperature in the fourth storage tank D4 gradually rises to 95°C (the tank may originally contain a second medium-low temperature fluid medium at 87°C. When the system is running, the second medium-low temperature fluid medium at 87°C is gradually discharged into the fifth main pipeline G5 through the seventh branch pipe G17).

[0112] like Figure 1 and Figure 8 After the heat pump unit is shut down, the high-temperature fluid medium in the fourth storage tank D4 is output to the third main pipe G3. After passing through the saccharification cleaning heat exchange unit B2 and / or the filtration cleaning heat exchange unit B4 and / or the alkali heat exchange unit C3 and / or the equipment flushing heat exchange unit C6, it cools down to a second medium-high temperature fluid medium of 87°C. This 87°C second medium-high temperature fluid medium enters the fifth main pipe G5, and then returns to the fourth storage tank D4 through the seventh branch pipe G17. As the amount of the 95°C high-temperature fluid medium decreases, the amount of the 87°C second medium-high temperature fluid medium increases. Ultimately, the fourth storage tank D4 stores the 87°C second medium-high temperature fluid medium. Therefore, when the heat pump unit is running, the fourth storage tank D4 gradually stores the 95°C high-temperature fluid medium, and when the heat pump unit is shut down, the fourth storage tank D4 gradually stores the 87°C second medium-high temperature fluid medium.

[0113] Multiple third energy storage tanks D3 and fourth energy storage tanks D4 can be used, and when multiple tanks are used, they are connected in series.

[0114] The energy storage tank plays the following role in the system:

[0115] 1) Enhance the economy and operational stability of heat pump systems: Energy storage tanks can be seen as buffers between heat sources and heat users, primarily used to balance heat loads (eliminate peak loads) and provide flexibility for heat sources (and distribution). This allows the unit to operate at higher efficiency, improving economy; it can meet peak loads of the heating system, reducing installed capacity and replacing peak-shaving heat sources; and it reduces the need for significant adjustments due to load changes, further improving economy.

[0116] 2) Consider peak and off-peak electricity pricing: Time-of-use pricing policies can be used to reduce operating costs. For example, during periods of high electricity prices, each heat pump unit stops operating and is heated by the energy storage tank. During periods of low electricity prices, such as late at night, the units are turned on at low cost to collect waste heat and convert it into high-grade thermal energy stored in the energy storage tank.

[0117] 3) Energy storage tanks are a guarantee for the safe operation of the heating network: When the water pumps in the heating system suddenly stop operating due to unexpected reasons, water hammer will occur. If the heating system is equipped with an energy storage tank, it will greatly alleviate the high-pressure oscillations caused by water hammer and reduce the damage and disasters caused by water hammer.

[0118] 4) The energy storage tank is a backup heat source for the heating system: when a heat source stops supplying heat for some reason, the energy storage tank can be put into operation in time to supplement the heat supply and prevent a large-scale heat outage.

[0119] As can be seen from the above, applying the energy storage tank to the system forms a combined multi-parameter wide-temperature-range energy storage and release coupling system, establishing a natural stratified energy zone for energy storage or release at any temperature within the range of 0℃ to 100℃. The fluid medium in each zone is continuous, and the inlet and outlet temperatures of each zone are variable and adjustable.

[0120] During energy storage, the system can select a suitable secondary temperature fluid medium from any zone inlet or outlet as a heat source to recover the cold-side medium, recovering heat from various dispersed points at different temperature levels. After the cold-side medium is heated, it becomes the hot-side medium for heat source recovery. According to different temperature levels, the hot-side medium is selectively distributed by the system into the corresponding temperature level of the energy storage and release coupling system to store energy, without disrupting the wide temperature range partitioning of the energy storage and release coupling system.

[0121] During energy release, the system can select a suitable temperature medium from any zone inlet and outlet. The heat source recovery hot side medium is transported to the process energy point by a circulating power conveying device to release heat, and then transformed into the heat source recovery cold side medium, returning to the energy storage and release system. According to different temperature levels, the system selectively allocates energy to the corresponding temperature level of the energy storage and release system to be replenished, without disrupting the wide temperature range zoning of the energy storage and release system.

[0122] The fragmented low-grade energy recovered by the combined multi-parameter wide-temperature-range energy storage and release coupling system can be stored in the system to adjust for differences in time and space. At the same time, it can also be partially used as a low-temperature heat source for industrial-grade high-temperature heat pumps. If the heat pump system requires more low-temperature heat source than the recovered fragmented low-grade energy, the energy storage and release coupling system will release low-grade heat source to supplement the heat pump system to adjust the imbalance between heat recovery and energy consumption.

[0123] When energy storage and release systems are combined with heat pump systems, they have the ability to be turned on or off at different times, fully realizing the system's flexibility in balancing scattered, intermittent, and asynchronous energy consumption.

[0124] like Figures 9 to 11The structure of each of the aforementioned energy storage tanks for storing fluid media is as follows: It includes a tank body 10 and a first water distributor. The tank body 10 is preferably made of boiler steel plate. The first water distributor is located inside the tank body 10 and includes a first inlet pipe 11, a first connecting pipe 12, a first distribution pipe 13, and a first outlet pipe 14.

[0125] like Figures 9 to 11 There are multiple first connecting pipes 12, which are distributed around the first input pipe 11. One end of the first connecting pipe 12 is fixed to the first input pipe 11, and the other end of the first connecting pipe 12 is fixed to the first distribution pipe 13.

[0126] like Figures 9 to 11 There are multiple first output pipes 14. Each first output pipe 14 has several first water outlet holes 14a on its upper, lower, left, and right sides to reduce flow field disturbances inside the energy storage tank. One end of each first output pipe 14 is fixed to the first distribution pipe 13. The diameter of each first water outlet hole 14a can be the same or different. For example, the diameter of the first water outlet hole 14a increases sequentially from one end of the first output pipe 14 to the other end. A first support plate 19 is fixed to the inner wall of the tank body 10. The end of the first output pipe 14 is fixed to the first support plate 19. The first support plate 19 is fixed to the tank body 10 and the first output pipe 14 by welding.

[0127] like Figures 9 to 11 It also includes a second water distributor, which is located inside the tank 10. The second water distributor and the first water distributor are arranged one above the other inside the tank 10. The second water distributor includes a second input pipe 15, a second connecting pipe 16, a second distribution pipe 17, and a second output pipe 18. One end of the second connecting pipe 16 is fixed to the second input pipe 15, and the other end of the second connecting pipe 16 is fixed to the second distribution pipe 17. There are multiple second connecting pipes 16, which are distributed around the second input pipe 15. One end of the second connecting pipe 16 is fixed to the second input pipe 15, and the other end of the second connecting pipe 16 is fixed to the second distribution pipe 17.

[0128] like Figures 9 to 11There are multiple second output pipes 18. Each second output pipe 18 has several second water outlet holes 18a on its upper, lower, left, and right sides to reduce flow field disturbances inside the energy storage tank. One end of the second output pipe 18 is fixed to the second distribution pipe 17. The diameter of each second water outlet hole 18a can be the same or different. For example, the diameter of the second water outlet hole 18a increases sequentially from one end of the second output pipe 18 to the other end. A second support plate 20 is fixed to the inner wall of the tank body 10, and the other end of the second output pipe 18 is fixed to the second support plate 20. The second support plate 20 is fixed to the tank body 10 and the second output pipe 18 by welding.

[0129] like Figures 9 to 11 The first input pipe 11 and the second input pipe 15 are respectively connected to the branch pipes in the above system. For example, the first input pipe 11 is connected to the first branch pipe G11, and the second input pipe 15 is connected to the second branch pipe G12.

[0130] like Figures 9 to 11 In this invention, since multiple water outlets are provided on each side of the output pipe in the water distributor, the increase in the number of water outlets and the improvement in the uniformity of water output are achieved. This also reduces the flow rate and pressure of the fluid medium after it is output from the output pipe. Therefore, the fluid medium can be smoothly output into the tank 10, thereby reducing fluid disturbance in the tank 10, reducing the mixing of hot and cold fluids, controlling the generation of less hot and cold mixed fluid, that is, generating a thinner temperature slope layer to improve heat storage efficiency.

[0131] like Figures 9 to 11 The energy storage tank also includes an outer sheath 21 and an insulation layer 22. The outer sheath 21 surrounds the tank body 10, forming a space between the tank body 10 and the outer sheath 21. The insulation layer 22 is installed in the space. The outer sheath 21 is preferably made of galvanized iron sheet with a thickness of 0.5mm, while the insulation layer 22 is made of materials such as foam plastic or rigid polyurethane core board. The insulation layer 22 can prevent heat loss from the tank body 10, allowing the stored medium to be kept at a constant temperature for a long time.

[0132] like Figures 9 to 11 The outer sheath 21 is provided with one or more sensor mounting ports 22. In this embodiment, the outer sheath 21 is provided with multiple sensor mounting ports 22. These sensor mounting ports 22 are used to install temperature sensors, pressure sensors, liquid level sensors, etc. Since the sensors need a power supply when they work and also need to feed back the detected signals to the controller (not shown in the figure), the energy storage tank in this embodiment also includes a cable sleeve 23 for electrical connection with the sensors. The cable sleeve 22 is arranged along the interval space.

[0133] like Figures 9 to 11The cable is installed inside the cable sleeve 23, which protects the cable. The cable sleeve 23 is installed in the space, and the outer sheath 21 protects the cable sleeve 23, preventing damage to the cable sleeve 23 and thus protecting the cable.

[0134] like Figures 9 to 11 After the tank 10 has been storing fluid media for a long time, some dirt, such as scale, will inevitably accumulate on the inner surface of the tank 10.
