Description

Technical Field

[0001] The invention relates to the technical field of wine making, and in particular to a high-efficiency energy-saving system for wine making. Background Art

[0002] In the process of liquor production, there is a step of distilling liquor, which is referred to as distilling liquor. As far as the inventors know, steam heating is usually used to distill liquor, and the distilled liquor vapor is cooled by cooling water to become liquid liquor. In this process, a large amount of steam and a large amount of cooling water are required. Steam is generally produced by steam boilers or purchased from outside. Cooling water was generally taken directly from nature, such as river water, etc. Now, due to environmental protection requirements, most cooling water uses a non-powered cooling system, and the heat absorbed in the cooling process is dissipated into the air through the non-powered cooling system, and the cooling water is recycled after cooling.

[0003] The inventor knows a currently commonly used wine distillation system such as Figure 1 As shown, an unpowered cooling system is adopted. The steamer barrel filled with mash is heated by steam, and the steam from the steam is cooled into liquid wine through a heat exchanger (cooler). The cooling water is cooled by the unpowered cooling system and then recycled. The heat of the cooling water is finally dissipated into the atmosphere through a cooling tower.

[0004] The wine distillation process of winemaking requires a large amount of steam, which consumes a lot of energy. At the same time, a large amount of low-grade heat is directly discharged into the atmosphere, resulting in energy waste. The unpowered cooling system solves the water problem and saves a lot of water resources compared to the previous method of taking water from nature, but it cannot solve the energy consumption problem. Therefore, there is an urgent need for a solution that can reduce the energy consumption of wine distillation to solve the above problems. Summary of the invention

[0027] The purpose of the present invention is to provide an efficient and energy-saving system for wine making to solve the problems existing in the prior art, recover the low-grade heat directly discharged into the atmosphere and utilize it in the wine distillation process, thereby greatly reducing the energy consumption of wine distillation.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please refer to Figure 2The present invention provides an efficient energy-saving system for brewing wine, comprising a steamer barrel 1, a primary heat exchanger 5, a secondary heat exchanger 37, a high-temperature heat pump 19 and a flash tank 23, wherein the primary heat exchanger 5 comprises a first heat supply path 3 and a first heat absorption path 4 for heat exchange, the secondary heat exchanger 37 comprises a second heat supply path 36 and a second heat absorption path 35 for heat exchange, and the high-temperature heat pump 19 comprises a third heat supply path 18 and a third heat absorption path 20 for heat exchange; the wine vapor outlet 2 of the steamer barrel 1 is connected to the inlet of the first heat supply path 3, and the outlet of the first heat supply path 3 is connected to the second heat supply path 3. The inlet of the second heat supply path 36 is connected to the wine storage device; the outlet of the first heat absorption path 4 is connected to the inlet of the third heat supply path 18, and the outlet of the third heat supply path 18 is connected to the inlet of the first heat absorption path 4; the inlet of the second heat absorption path 35 is connected to the first cold source 28, the outlet of the second heat absorption path 35 is connected to the inlet of the third heat absorption path 20, the outlet of the third heat absorption path 20 is connected to the liquid inlet 22 of the flash tank, the liquid outlet 24 of the flash tank is connected to the inlet of the third heat absorption path 20, and the air outlet 21 of the flash tank is connected to the air inlet 39 of the retort barrel.

[0030] The working principle of the present invention is:

[0031] The wine vapor in the steamer barrel 1 flows out from the wine vapor outlet 2 of the steamer barrel 1, and flows into the first heat supply path 3 of the primary heat exchanger 5 and the second heat supply path 36 of the secondary heat exchanger 37 in sequence as a high-temperature heat exchange medium. The low-temperature medium in the first cold source 28 flows into the second heat absorption path 35 of the secondary heat exchanger 37, and the medium-temperature medium in the circulation loop formed by the first heat absorption path 4 and the third heat supply path 18 flows into the first heat absorption path 4 of the primary heat exchanger 5.

[0032] In this way, the wine vapor as the high-temperature medium first undergoes a first heat exchange with the medium-temperature medium in the first heat absorption path 4 in the first heat supply path 3 of the primary heat exchanger 5, and is condensed into high-temperature liquid wine. Then, in the state of high-temperature liquid wine, it undergoes a second heat exchange with the low-temperature medium in the second heat absorption path 35 in the second heat supply path 36 of the secondary heat exchanger 37, and becomes low-temperature liquid wine.

[0033] The low-temperature medium in the first cold source 28 exchanges heat with the high-temperature liquid wine that has undergone heat exchange and cooling in the secondary heat exchanger 37. The low-temperature medium is usually low-temperature softened water. The softened water that has absorbed heat flows into the loop composed of the third heat absorption path 20 of the high-temperature heat pump 19 and the flash tank 23, so as to replenish water for the flash tank 23 that produces steam; the medium-temperature medium in the circulation loop formed by the first heat absorption path 4 and the third heat supply path 18 flows into the first heat absorption path 4, and after heat exchange and heat absorption with the high-temperature wine vapor in the first heat supply path 3 that has just flowed out of the steamer barrel 1 and has not undergone heat exchange, it flows into the third heat supply path 18 of the high-temperature heat pump 19 as a heat supply medium, and provides thermal energy for heating the heat absorption medium in the third heat absorption path 20 of the high-temperature heat pump 19. The medium that releases heat in the third heat supply path 18 flows into the first heat absorption path 4 in a medium-temperature state, forming a cycle. In this way, the heating medium in the first-stage heat exchanger 5 is the high-temperature wine vapor just flowing out of the steamer barrel 1, the heat-absorbing medium is the medium-temperature medium flowing out of the third heating path 18 of the high-temperature heat pump 19, and the heating medium in the second-stage heat exchanger 37 is the high-temperature liquid wine that has undergone one heat exchange and cooling for heat exchange, and the heat-absorbing medium is the low-temperature medium with the lowest temperature in the first cold source 28, so that the temperature difference between the heat-absorbing medium and the heating medium in the heat exchange in the first-stage heat exchanger 5 and the second-stage heat exchanger 37 can be maintained within a small range, which is beneficial to improving the absorption rate of thermal energy and reducing thermal energy waste.

[0034] Finally, the low-temperature medium and the medium-temperature medium that have absorbed the heat energy of the wine vapor flow into the high-temperature heat pump 19, providing heat energy for the high-temperature heat pump 19 to generate high-temperature water above 120°C, and the high-temperature water above 120°C then produces steam through the flash tank 23, and the produced steam is then transported to the steamer barrel 1 for wine distillation. In this way, the heat recovered from the wine vapor provides heat energy for the high-temperature heat pump 19 and the flash tank 23 to produce steam, and the heat energy of the wine vapor is effectively recovered and reused.

[0035] The standard boiling point of alcohol is about 78.32℃, which is lower than the boiling point of water. An important principle of distilling wine is to release the wine slowly. During the distillation process, after the wine starts to be released, the steam pressure must be controlled to control the speed of the wine flowing out of the wine outlet, so as to ensure the quality of the wine.

[0036] Another principle of distilling liquor is to control the temperature of the liquor. Different types of liquor have different requirements. Generally, both Luzhou-flavor liquor and Qing-flavor liquor emphasize "low temperature liquor", and the liquor temperature does not exceed 30°C. However, Maotai-flavor liquor emphasizes "high temperature liquor", and the liquor temperature can reach 40°C or even 45°C, which is a feature of Maotai-flavor liquor. The temperature requirements of cooling water vary according to the different types of liquor. Generally, it is required to be 5°C lower than the liquor temperature, and the cooling water is generally heated to above 75°C.

[0037] In order to meet the above temperature requirements, a three-way regulating valve 6 is provided at the outlet of the first heat absorption path 4. The outlet of the first heat absorption path 4 is connected to the first inlet 7 of the three-way regulating valve, the outlet of the third heat supply path 18 is connected to the second inlet 8 of the three-way regulating valve, and the outlet 9 of the three-way regulating valve is connected to the inlet of the third heat supply path 18. By providing the three-way regulating valve 6, a branch that short-circuits the first heat absorption path 4 is formed. By adjusting the opening of the first inlet 7 and the second inlet 8 of the three-way regulating valve, the flow rate of the medium-temperature medium entering the first heat absorption path 4 is adjusted. When the flow rate is large, more heat is absorbed from the first heat supply path 3, that is, the temperature of the wine vapor is reduced more. When the flow rate is small, the heat absorbed from the first heat supply path 3 is also small, so that the temperature of the wine vapor is reduced less, thereby ensuring that the temperature of the high-temperature liquid wine is within the required range.

[0038] Furthermore, a first water pump 17 is provided on the circulation loop formed by the first heat absorption path 4 and the third heat supply path 18, a second water pump 25 is provided on the circulation loop formed by the flash tank 23 and the third heat absorption path 20, and a third water pump 26 is provided between the second heat absorption path 35 and the third heat absorption path 20. The first water pump 17 and the second water pump 25 serve as power sources for their respective circulation loops, and the third water pump 26 is used to pump the medium in the first transition box 27 into the loop formed by the third heat absorption path 20 and the flash tank 23 when the water source in the flash tank 23 is insufficient, so as to replenish the flash tank 23 with water.

[0039] A first transition box 27 is provided between the outlet of the second heat absorption path 35 and the inlet of the third heat absorption path 20, the outlet of the first transition box 27 is connected to the inlet of the third water pump 26, and the outlet of the third water pump 26 is connected to the inlet of the second water pump 25. A two-way regulating valve 34 is provided between the outlet of the second heat absorption path 35 and the first transition box 27.

[0040] The role played by the two-way regulating valve 34 is similar to that of the three-way regulating valve 6. It controls the degree of heat absorption by directly adjusting the flow rate of the low-temperature medium in the second heat absorption path 35, so that the final wine output temperature is maintained within the required range.

[0041] The first transition box 27 is configured as a storage and transfer unit for the low-temperature medium, and stores a sufficient amount of the low-temperature medium after heat absorption flowing from the second heat absorption path 35, so that the flow rate and flow of the low-temperature medium flowing into the third heat absorption path 20 are not limited by the flow rate in the second heat absorption path 35 in front.

[0042] A second transition box 11 and a heating device 14 are arranged between the three-way regulating valve 6 and the high-temperature heat pump 19. The outlet 9 of the three-way regulating valve is connected to the first inlet 10 of the second transition box, the first outlet 12 of the second transition box is connected to the inlet of the heating device 14, the outlet of the heating device 14 is connected to the second inlet 15 of the second transition box, and the second outlet 16 of the second transition box is connected to the inlet of the third heating path 18. A fourth water pump 13 is arranged on the circulation loop formed by the second transition box 11 and the heating device 14 as a power source for the circulation loop. The second transition box 11 plays a role in storing and buffering hot water, and the heating device 14 generates the heat source required when the system is started or supplements the insufficient heat of the system operation. The heating device 14 can use electric heating or other heat sources.

[0043] In one embodiment, it also includes a sewage heat exchanger 32, which includes a fourth heat supply path 33 and a fourth heat absorption path 31. The inlet of the fourth heat supply path 33 is connected to the bottom water outlet 38 of the steamer drum 1, and the outlet of the fourth heat supply path 33 is connected to the sewage outlet; the inlet of the fourth heat absorption path 31 is connected to the second cold source 29, and the outlet of the fourth heat absorption path 31 is connected to the first transition tank 27. The sewage heat exchanger 32 recovers the waste heat of sewage, and the cold source is also low-temperature softened water. After heat exchange, it enters the first transition tank 27 and is finally used as water replenishment for the flash tank 23. The third water pump 26 is started to replenish water according to the liquid level control. The first cold source 28 and the second cold source 29 can use different water sources, or they can use the same water source and divide it into two ways for use.

[0044] In one embodiment, an intelligent control cabinet is configured, and the intelligent control cabinet is configured with an Internet of Things touch screen, a controller, a collector, a frequency converter, etc., and a communication card to realize intelligent control and remote APP monitoring.

[0045] Further, temperature sensors are provided at the inlet of the first heat supply path 3, between the first heat supply path 3 and the second heat supply path 36, at the outlet of the second heat supply path 36, at the inlet and outlet of the third heat supply path 18, at the inlet and outlet of the fourth heat supply path 33, as well as at the outlet and outlet of the first heat absorption path 4, at the outlet and outlet of the second heat absorption path 35, at the outlet and outlet of the third heat absorption path 20, and at the inlet and outlet of the fourth heat absorption path 31, so as to monitor the temperature of the low-temperature medium and the high-temperature medium in real time. Similarly, temperature sensors are also provided at the outlet of the first transition box 27, at the air outlet 21 of the flash tank, and in the second transition box 11. A heat meter is provided at the liquid inlet of the flash tank 23, a liquid level transmitter is provided in the first transition box 27, the second transition box 11, and the flash tank 23, and a water flow switch is provided on the sewage side of the sewage heat exchanger 32 at the outlet of the fourth heat supply path 33. The electronic components and water pumps in this system are all connected to the controller signal.

[0046] Please refer to the figure, where the dotted lines represent the signal connection relationship between the components. The main control logic of the present invention is as follows:

[0047] (1) The switch valve 30 of the sewage heat exchanger 32 is associated with the water flow switch on the sewage side. When the water flow switch is activated, it means that sewage is being discharged. At this time, the switch valve 30 is opened to exchange heat with softened water. In addition, when the liquid level of the first transition tank 27 is detected to be low, the switch valve 30 is opened to replenish water.

[0048] (2) The three-way regulating valve 6 at the primary heat exchanger 5 adjusts the opening of the three-way regulating valve 6 according to the set liquid wine temperature setting value and the actual liquid wine temperature through the PID (Proportional Integral Derivative) control system, thereby maintaining a constant liquid wine temperature.

[0049] (3) The two-way regulating valve 34 at the secondary heat exchanger 37 adjusts the opening of the electric regulating valve through the PID control system according to the set wine outlet temperature setting value and the actual wine outlet temperature, thereby maintaining a constant wine outlet temperature.

[0050] (4) Function of the heating device 14:

[0051] First, when the system starts running, there is no high-temperature waste hot water to use, and some heat must be generated first by other means. Other heating methods such as electric heating can also be used here to heat the hot water tank.

[0052] The second is to supplement the system heat when the residual heat of the entire system is insufficient.

[0053] The heating device 14 can be started and stopped by time or demand control.

[0054] (5) The high temperature heat pump 19 generates high temperature hot water exceeding 120° C. by recovering heat from hot water, which is used to produce steam.

[0055] (6) The flash tank 23 is used to flash steam, and the make-up water required after the flash steam is obtained from the first transition tank 27.

[0056] (7) Monitor the heat generation of the system through a heat meter, monitor the power consumption of the system through a smart meter, and calculate the heat pump COP (Coefficient Of Performance) and the system comprehensive COP.

[0057] (8) The start and stop of the high-temperature heat pump 19, the second-source high-temperature heat pump 19, the first water pump 17, the second water pump 25, the third water pump 26, the fourth water pump 13, etc. are realized by the controller.

[0058] Figure 4The invention shows a relatively common application state. The first-stage heat exchanger 5 uses 65℃ medium-temperature water to cool the wine vapor above 90℃ to 70℃ liquid wine. The second-stage heat exchanger 37 uses room-temperature softened water to cool the 70℃ liquid wine to 25-40℃. The waste heat exchanger 32 is used to recover the heat of the bottom water. Finally, the recovered heat is used to produce steam through the high-temperature heat pump 19 and the flash tank 23, and the produced steam is then transported to the steamer barrel 1 for wine distillation. The water temperature of different parts of different systems will be different.

[0059] This system can recover more than 60% of waste heat, save more than 60% of energy, and no longer require an unpowered cooling system. It is a very efficient and energy-saving system for the liquor brewing industry.
