[0018] Among them, the softening device is connected to the first heat exchanger 3 through a pipeline, one end of the first heat exchanger 3 is connected to the wine distillation pot 5 through the wine brewing cooler 4, the wine distillation pot 5 is connected to the steam injection liquid enthalpy increase and recompression unit 10, the other end of the first heat exchanger 3 is connected to the flash tank 9, the flash tank 9 is connected to the steam injection liquid enthalpy increase and recompression unit 10 to form a first heat exchange loop; the high-temperature and high-pressure steam generated by the steam injection liquid enthalpy increase and recompression unit 10 is guided to the flash tank 9 for purification of alcohol or other components, the wine distillation pot 5 requires heat energy supply, and at this time, the high-temperature and high-pressure steam can be obtained from the steam injection liquid enthalpy increase and recompression unit 10.

[0019] The two ends of the ultra-high temperature water source heat pump 6 are also connected to the flash tank 9 and the first heat exchanger 3 through pipelines to form a second heat exchange loop; the lithium bromide double-effect absorption refrigerator is connected to the airing machine 12, and the inlet of the lithium bromide double-effect absorption refrigerator is connected to the steam spray liquid enthalpy increase recompression unit 10, and the outlet of the lithium bromide double-effect absorption refrigerator is connected to the hot water inlet of the ultra-high temperature water source heat pump 6 to form a third heat exchange loop. The airing machine 12 is an independent setting for drying brewing raw materials or products, and is not directly connected to other equipment. The specific structure of the airing machine 12 is not introduced in detail here. The lithium bromide double-effect absorption refrigerator is a refrigeration setting for breweries. It is connected to the airing machine 12 that needs refrigeration to accelerate the rapid cooling of the brewing raw materials or products on the airing machine 12.

[0020] In the third loop, the cold water inlet and outlet of the lithium bromide double-effect absorption refrigerant 11 is connected to the hot water inlet of the ultra-high temperature water source heat pump 6, and energy transfer is realized through pipelines, so that the waste heat generated by the lithium bromide double-effect absorption refrigerator can be used for heating the hot water of the ultra-high temperature water source heat pump 6, thereby improving energy recovery and reuse; the lithium bromide double-effect absorption refrigerator is a special refrigeration equipment that uses lithium bromide and water as working fluids to achieve a refrigeration effect in an absorption refrigeration cycle. The refrigerant is an existing product and its specific structure is not introduced here.

[0021] Specifically, it also includes a second heat exchanger 7, the second heat exchanger 7 is connected to the first heat exchanger 3 through a pipeline, and the second heat exchanger 7 is connected to the winemaking cooler 4 to form a fourth heat exchange loop.

[0022] Furthermore, in the second heat exchange loop, both ends of the ultra-high temperature water source heat pump 6 are also connected to the second heat exchanger 7 for energy transfer.

[0023] Specifically, a water tank 8 is further provided between the second heat exchanger 7 and the ultra-high temperature water source heat pump. Preferably, both the first heat exchanger 3 and the second heat exchanger 7 are plate heat exchangers.

[0024] The soft water treatment equipment 1 extracts softened water to the first heat exchanger 3 through a pipeline for cooling and heating operations of the first heat exchanger 3 ; the first heat exchanger 3 and the second heat exchanger 7 are used for heat energy exchange in the brewing cooler 4 .

The brewing cooler 4 is used to cool the hot liquid generated during the brewing process.

[0026] This structure is based on the problem of poor utilization of waste heat in the wine brewing process in the liquor industry. The hot water (40-80°C) generated by the wine steamer 5 and the wine cooler 4 is used as the waste heat source. The waste heat is recycled and utilized by the ultra-high temperature water source heat pump 6 to produce hot water with a temperature not exceeding 125°C. The flash tank 9 is matched to produce saturated steam with a pressure not exceeding 0.2MPa. The saturated steam is further processed by the steam injection enthalpy increase recompression unit 10 to increase the steam parameters to a higher level (temperature ≤180°C). The produced high-temperature steam is used for the wine steamer 5. Through the closed-loop application of waste heat, the energy consumption and water consumption of wine brewing are significantly reduced, the natural gas consumption is reduced by more than 50%, the water consumption of the wine steamer cooling is reduced by more than 60%, the sewage treatment volume is reduced, and thermal pollution is avoided, which promotes the construction of a zero-carbon wine enterprise. Furthermore, in order to address the prominent problem of high-temperature emissions in wineries in summer, when the outdoor temperature is ≥35°C, the high-temperature steam produced above is used as the heat source, and chilled water is prepared by a lithium bromide double-effect absorption refrigerator. The chilled water is sent to the workshop drying machine 12 to perform enhanced cooling on the mash, reduce the temperature of the wine entering the pool, inhibit the degradation of liquor in summer, extend the production cycle of the wine company in summer, and further reduce costs and increase efficiency.
