Description

Technical field:

[0001] The invention relates to the technical field of wine making, and in particular to an intelligent wine cooler energy-saving and emission-reduction system. Background technology:

[0002] In the brewing industry, especially in the liquor distillation system, the fermented mash is distilled through a distillation device (i.e., a wine retort) to obtain liquor vapor, which is then transported to a cooling device, where it exchanges heat with cooling water. The liquor vapor is condensed into liquid liquor and transported to the liquor container through the liquor outlet at the bottom. The cooling water in the cooling device becomes high-temperature cooling water with a temperature of approximately 80-90°C after heat exchange, and is finally discharged through a pipeline. The existing method of directly discharging cooling water not only wastes water resources, but also wastes a lot of energy, which in turn leads to a high production cost of liquor. How to recover the heat taken away with high quality is a technical problem that urgently needs to be solved.

[0003] The Chinese invention with the authorization announcement number CN214142273U discloses a wine distillation device equipped with steam heat recovery, which includes a wine distillation machine, a water-cooled heat exchange condensation cooler, an evaporator of an air heat pump, a compressor of the air heat pump, a pressurized heat preservation water tank, and a steam generator; the wine distillation machine is connected to the steam air inlet of the evaporator of the air heat pump, and the steam air inlet is connected to the inlet end of the water-cooled heat exchange condensation cooler; the inlet end of the water-cooled heat exchange condensation cooler is connected to a tap water pipe, and a water replenishment float valve is provided between the tap water pipe and the water-cooled heat exchange condensation cooler, and the outlet end of the compressor of the air heat pump is connected to the pressurized heat preservation water tank; the outlet end of the pressurized heat preservation water tank is connected to the steam generator through a booster water pump, and the top of the steam generator is connected to the wine distillation machine. The purpose of this patent is to solve the problem of energy waste caused by direct discharge of steam after wine distillation, and realize the process application of energy utilization and constant temperature wine output.

[0004] The above-mentioned wine distillation equipment equipped with steam heat recovery directly utilizes the heat released by the water-cooled heat exchanger condenser cooler for the air energy heat pump, thereby achieving the effect of heat recovery and reuse, rather than using the heat energy (i.e., high-temperature cooling water) again for liquor brewing. As a result, enough steam is still needed to steam grain in the wine retort (a device for generating wine vapor) to form wine vapor, and thus cannot reduce the electricity or gas consumed by equipment such as electric boilers or gas boilers that provide steam to the wine retort, causing great trouble to users.

Description of the drawings:

[0018] Figure 1 It is a structural diagram of the present invention. Specific implementation method:

[0019] The present invention is further described below in conjunction with specific embodiments and drawings.

[0020] See Figure 1As shown, the intelligent wine cooler energy-saving and emission reduction system includes: a wine retort 1, a heat exchange module 2, a heat recovery water tank 3, a cooling tower module 4, a flash tank 5, a first-stage ejector 6, a second-stage ejector 7, a third-stage ejector 8, a steam cylinder 9 and a boiler 10.
