Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology in brewing distillation, specifically a device for recovering and reusing waste heat from brewing distillation. Background Technology

[0002] In the brewing industry, distillation is an indispensable step, involving the steam heating and evaporation of the mash, followed by cooling and condensation to separate the base spirit. However, in traditional distillation, the steam primarily comes from the boiler, which not only consumes enormous amounts of energy but also generates greenhouse gases. During the cooling stage, whether using water or air cooling, the residual heat from the cooling water and exhaust air often exceeds 50°C. The energy waste and inefficiency in this process urgently need to be addressed.

[0003] The existing technology, patent application number 202411516249.8, describes a waste heat recovery type brewing distillation system and method, which includes: a ground pot equipment, a still, a precooler, a waste water pump, a regenerative evaporator, a first refrigerant compressor, a first throttling valve, a steam generator, an intermediate tube sheet, and a condensation recovery device. Through multiple sets of waste heat recovery devices, it achieves full recovery and utilization of waste heat during the wine cooling process; through the steam generator, the still, and related devices, it achieves autonomous steam generation, reducing the input of external energy; through the precooler and the condensation recovery device, it achieves gradient cooling of the wine vapor, reducing the wine cooling output temperature and increasing the wine yield. However, the condensation effect is generally poor, the structure is complex, and it is not convenient for small-scale brewing workshops to use. Utility Model Content

[0004] The purpose of this invention is to provide a device for recovering and reusing waste heat from brewing distillation, so as to solve the problems of the existing technology having a general condensation effect, complex structure, and being inconvenient for small brewing workshops.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a brewing distillation waste heat recovery and reuse device, including a heating base, a distillation chamber on the upper side of the heating base, a condensation box on the upper cover of the distillation chamber, a spiral condenser tube in the middle of the condensation box, a steam exhaust pipe connecting the spiral condenser tube and the distillation chamber, a wine receiving barrel connected to one side of the bottom of the spiral condenser tube via a connecting pipe, a cold water inlet pipe and a hot water outlet pipe on one side of the condensation box, a first stirring blade on the bottom of the condensation box via a stirring motor, a second stirring blade and a third stirring blade on the upper side of the first stirring blade, and cleaning brush bristles on one side of the second stirring blade and the third stirring blade for cleaning the outside of the spiral condenser tube.

[0006] Furthermore, the cold water inlet pipe is equipped with a first valve and an inlet pump, and the hot water drain pipe is equipped with a second valve and a drain pump.

[0007] Furthermore, both the first and second valves are solenoid valves, and the first valve, the inlet pump, the second valve, and the drain pump are all electrically connected to a controller outside the heating base.

[0008] Furthermore, the second and third stirring blades are provided in two sets symmetrically about the first stirring blade, and both the second and third stirring blades are welded perpendicularly to the first stirring blade.

[0012] 1. This utility model features a spiral condenser tube in the center of the condensing chamber, with a cold water inlet pipe and a hot water outlet pipe on one side. Cold water is injected into the condensing chamber through the cold water inlet pipe to submerge the spiral condenser tube, thus water-cooling the outside of the spiral condenser tube. This improves the efficiency of brewing distillation condensation. At the same time, steam preheating can heat the water in the condensing chamber. After the water reaches a certain temperature, it is discharged through the hot water outlet pipe for daily hot water use. Then, new cold water is injected again to water-cool the outside of the spiral condenser tube. Moreover, the condensation effect is good, the structure is simple, and it is easy for small brewing workshops to use.

[0013] 2. In this utility model, the bottom of the condenser is equipped with a first stirring blade via a stirring motor, and a second stirring blade and a second stirring blade are provided on the upper side of the first stirring blade.

Furthermore, the second stirring blade and the second stirring blade are each equipped with cleaning bristles on one side. When the stirring blade drives the cleaning bristles to rotate horizontally, the outside of the spiral condenser tube can be cleaned to prevent water quality and dust from adhering to the outside of the spiral condenser tube and affecting the heat exchange and condensation efficiency.

[0014] 3. The present invention has a box wall scraper provided on the side wall of the second stirring blade, and the box wall scraper adopts a rubber triangular plate structure. When the second stirring blade and the box wall scraper rotate horizontally, they can scrape off the dust on the inner wall of the condensing box, thereby facilitating the cleaning of the inner wall of the condensing box.

Cold water is injected into the condensing box 4 through the cold water inlet pipe 8 to cover the spiral condenser tube 16 for water cooling of the outside of the spiral condenser tube 16, which is beneficial to improve the efficiency of brewing distillation condensation. At the same time, the steam preheating can heat the water in the condensing box 4. After the water reaches a certain temperature, it is discharged through the hot water drain pipe 11 for daily hot water use. Then, new cold water is injected again to water cool the outside of the spiral condenser tube 16.

[0022] like Figure 2 and Figure 3 As shown, in order to maintain a uniform water temperature in the condenser 4, a first stirring blade 18 is provided at the bottom of the condenser 4 via a stirring motor 17. A second stirring blade 19 and a third stirring blade 21 are provided on the upper side of the first stirring blade 18. The second stirring blade 19 and the third stirring blade 21 are symmetrically arranged in two sets about the first stirring blade 18, and both the second stirring blade 19 and the third stirring blade 21 are welded perpendicularly to the first stirring blade 18. This allows the stirring blades to rotate at a uniform speed driven by the stirring motor 17, which can stir and mix the water inside the condenser, thus facilitating the maintenance of a uniform water temperature in the condenser 4.

After the water reaches a certain temperature, it is discharged through the hot water outlet pipe 11 for daily hot water use. Then, new cold water is injected again to water-cool the outside of the spiral condenser 16.
