Description

Technical Field

[0001] This application relates to the field of brewing equipment technology, and in particular to an improved heat recovery device for brewing equipment. Background Technology

[0002] In a baijiu distillation system, fermented mash is distilled using a still (i.e., a still) to produce alcohol vapor. This vapor is then transported to a cooler, where it is condensed and cooled to room temperature to become liquid baijiu. The coolant in the cooler undergoes heat exchange, becoming a high-temperature coolant at approximately 80-90°C. Finally, it is cooled again by an external cooling device and then recycled.

[0003] Current beverage cooling processes connect beverage vapor to a steam inlet at the top of a beverage cooler. As the vapor is continuously generated and accumulates, it creates pressure, propelling the vapor downwards into the cooler for cooling. When the vapor pressure is insufficient, it may float and accumulate in the upper space of the cooler, or even backflow may occur, resulting in poor cooling and reduced heat recovery efficiency.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the scope of the present application.

[0029] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0030] The terms "installation," "connection," and "linking" used in this specification should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two components. Those skilled in the art will understand the specific meaning of these terms in this invention based on the specific circumstances. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] This application provides an improved heat recovery device for a wine cooler. When the wine vapor pressure is insufficient, the downward-curving plate shape of the condenser plate can block the wine vapor, effectively preventing the wine vapor from flowing back, improving the wine cooling effect, and increasing the heat recovery efficiency.

[0032] The following describes in detail, with reference to the accompanying drawings, an improved heat recovery device for a wine cooler provided in this embodiment. Figure 1 As shown, the improved wine cooler heat recovery device includes: an improved wine cooler 01 and a heat recovery unit 02. The improved wine cooler 01 includes a housing 1 and a heat exchange assembly installed inside the housing 1. The heat exchange assembly includes a condensing unit 2, a cooling unit 3, and a subcooling unit 4, which are distributed from top to bottom inside the housing 1.

[0033] The condensing unit 2 includes multiple condensing plates 20. Each condensing plate 20 is a downward-curved plate with an opening. The condensing plates 20 are stacked, with gaps between each layer and arranged parallel to each other. Adjacent layers of condensing plates 20 are also spaced apart and staggered to facilitate the passage of alcohol vapor. The cross-section of the condensing plate 20 is either a downward-curved arc or a downward-bent folded plate. The gaps between the condensing plates 20 serve as the alcohol channels in the condensing unit 2. When alcohol vapor passes from top to bottom, it condenses into liquid upon encountering the low-temperature condensing plates 20 and falls downwards. Simultaneously, because the condensing plates 20 are downward-curved, even if alcohol vapor flows upwards back, it will be blocked by the condensing plates 20 and condense on the lower curved surface of the condensing plates 20, thus preventing the alcohol vapor from flowing upwards back.

[0034] The shell 1 is divided into upper, middle and lower spaces by partition 10. The condenser plate 20, cooling unit 3 and subcooling unit 4 in the condensing unit 2 are located in the upper, middle and lower spaces respectively. The top of the shell 1 is provided with a wine vapor inlet 11 and the bottom is provided with a wine outlet 12. The heat exchange component has a wine channel that communicates with the wine vapor inlet 11 and the wine outlet 12. Wine vapor enters through the wine vapor inlet 11 and flows downward through the condensing unit 2, cooling unit 3 and subcooling unit 4 in sequence before flowing out as liquid wine through the wine outlet 12.

[0035] Heat recovery unit 02 is connected to the condensation channel of condensation unit 2 to recover the heat absorbed by condensation unit 2. Since the coolant in condensation unit 2 is the highest-temperature heat exchanger during operation, the heat absorbed by cooling unit 3 and subcooling unit 4 is not recovered. The cooling channels in cooling unit 3 and subcooling unit 4 can be connected in series, and the outflowing coolant can be cooled by an external condensation tower and then recycled. Because the cooling temperature of the coolant in cooling unit 3 and subcooling unit 4 is not high, the energy consumption of the external condensation tower is low.

[0036] In this embodiment, the improved wine cooler 01 employs a three-stage cooling system. The first stage, which directly contacts the wine vapor, utilizes a novel condensation structure. The condensation unit 2, serving as the first stage, employs multiple evenly distributed condensation plates 20. When the wine vapor enters the housing 1, it condenses into liquid upon contact with the condensation plates 20, flowing downwards. Simultaneously, because the condensation plates 20 are downwardly curved, even if the wine vapor pressure is insufficient, their shape effectively prevents backflow, thus increasing heat recovery efficiency. Furthermore, the heat recovery unit 02 only recovers heat from the condensation unit 2, which has the highest heating temperature, ensuring that the devices requiring heating by the heat recovery unit 02 receive sufficient water temperature.

[0037] Specifically, condenser plates 20 have condenser plate channels 200 formed within them. The condenser plate channels 200 in each condenser plate 20 are interconnected and serve as the condensation channels for the condensation unit 2. The condenser plate channels 200 can be connected in series or in parallel. For example... Figure 2 As shown, the condenser channels 200 of each condenser plate 20 are connected in series, and then connected in series with the condenser plate 20 of the layer above, ultimately connecting all the condenser channels 200 of the condenser plates 20 in series from bottom to top. The condenser channels 200 in the condenser plates 20 can also be connected in a series-parallel combination. For example... Figure 3 As shown, the condenser channels 200 of each condenser plate 20 are connected in parallel, and the condenser channels 200 of the condenser plates 20 between layers are connected in series.

[0038] To facilitate the installation and connection of the condenser plate channel 200, such as Figure 4As shown, the condensing unit 2 also includes a connecting plate 23, on which a coolant inlet 21 and a coolant outlet 21 are provided. The connecting plate 23 is made of a metal sheet with good heat dissipation performance, and the condensing plate channels 200 of the condensing plates 20 are connected in series through the connecting plate 23. Specifically, the condensing plate channels 200 in each layer of condensing plates 20 are connected in series through the connecting plate 23, and the condensing plate channels 200 in adjacent layers of condensing plates 20 are connected in series through the connecting plate 23; or, the condensing plate channels 200 in each layer of condensing plates 20 are connected in parallel through the connecting plate 23, and the condensing plate channels 200 in adjacent layers of condensing plates 20 are connected in series through the connecting plate 23.

[0039] As one feasible approach, cooling unit 3 and subcooling unit 4 can be plate-and-shell heat exchangers. Cooling unit 3 has plate channels and shell channels. The plate channels serve as cooling channels for cooling unit 3, connecting to the inlet of the cooling channel of condensing unit 2 and the outlet of the cooling channel of subcooling unit 4, respectively. The shell channels serve as cooling channels for cooling unit 3, connecting to the outlet of the cooling channel of condensing unit 2 and the inlet of the cooling channel of subcooling unit 4, respectively.

[0040] Similarly, the subcooling unit 4 also has plate channels and shell channels. The plate channels serve as cooling channels for the subcooling unit 4, and are connected to the cooling channel inlet and coolant inlet of the cooling unit 3, respectively. The shell channels serve as wine channels for the subcooling unit 4, and are connected to the wine channel outlet and wine outlet 12 of the cooling unit 3, respectively.

[0041] When the heat recovery device of the improved wine cooler is working, for the wine vapor, firstly, the wine vapor enters the wine channel in the condensing unit 2 through inlet 11. After contacting the condensing plate 20, the wine vapor condenses into liquid wine, drips down and collects at the baffle 10 at the bottom of the condensing unit 2. Then, the condensed liquid wine enters the wine channel of the cooling unit 3. Next, the wine cooled by the cooling unit 3 enters the wine channel of the subcooling unit 4, and finally exits through the wine outlet 12 to obtain the desired low-temperature liquid wine.

[0042] As one possible way, such as Figure 5 As shown, the heat recovery unit 02 includes a first heat recovery unit 5, which includes a first heat exchanger 51 and an insulated water tank 52. The high-temperature side 5a of the first heat exchanger 51 is connected to the condensation channel of the condensation unit 2, and the low-temperature side 5b of the first heat exchanger 51 is connected to the insulated water tank 52. The coolant in the condensation channel of the condensation unit 2 heats the water in the insulated water tank 52 after passing through the first heat exchanger 51.

[0043] The coolant in the condensation channel flows out from the coolant inlet 21, passes through the first heat exchanger 51 to exchange heat and lower its temperature, and then re-enters the condensation channel of the condensation unit 2 through the coolant outlet 21. At the same time, it heats the water in the insulated water tank 52 after passing through the first heat exchanger 51.

[0044] The insulated water tank 52 is equipped with an insulated water outlet, which is connected to the first domestic water device 6 and is used to output hot water to the first domestic water device 6.

[0045] The first domestic water supply device 6 can be a shower and bathing device, which directly receives hot water from the insulated water outlet of the insulated water tank 52. Municipal tap water is used to regulate the water temperature for showering and bathing through a cold water inlet pipe. This insulated water outlet provides residents with a stable supply of hot water.

[0046] In addition, the insulated water tank 52 is also connected to a steam input device 53 to increase the water pressure in the insulated water tank 52 and ensure normal water supply.

[0047] As another possible implementation, the heat recovery unit 02 also includes a second heat recovery unit 7, which includes a second heat exchanger 71. The high-temperature side 7a of the second heat exchanger 71 is connected to the condensation channel of the condensation unit 2, and the low-temperature side 7b of the second heat exchanger 71 is connected to the second domestic water device 8. The coolant in the condensation channel of the condensation unit 2 heats the second domestic water device 8 through the second heat exchanger 71.

[0048] The second domestic water supply device 8 can be a heating pipe. To ensure the normal operation of the heating pipe, a first water supply tank 72 is provided to replenish water to the heating pipe of the second domestic water supply device 8.

[0049] In addition, the heat recovery device of the improved wine cooler is also equipped with a second water tank 9. The pipe of the second water tank 9 is connected to the condensation channel in the condensation unit 2, and the coolant of the condensation unit 2 is replenished through the second water tank 9.

[0050] As one feasible approach, the heat recovery device of the improved wine cooler recovers heat absorbed by the condensing unit 2 through a first heat recovery unit 5 and a second heat recovery unit 7. Specifically, the high-temperature side 5a of the first heat exchanger 51 in the first heat recovery unit 5 and the high-temperature side 7a of the second heat exchanger 71 in the second heat recovery unit 7 are connected in parallel to the condensing channel of the condensing unit 2. By switching valves, the condensing unit 2 can supply heat to both the first heat recovery unit 5 and the second heat recovery unit 7. Of course, multiple condensing units 2 of the wine cooler can also be connected in parallel, thus simultaneously supplying heat to both the first heat recovery unit 5 and the second heat recovery unit 7.

[0051] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
