Description
Technical Field
The utility model relates to a making wine field, especially a making wine is with unpowered refrigeration cooling circulation system.
Background
The brewing process of the white spirit is accompanied by high energy consumption and high water consumption, generally, 30-40 tons of water are consumed for producing one ton of white spirit, and if the white spirit is a Maotai-flavor type famous wine, even 50-60 tons of water are consumed for one ton of white spirit. In all water consumption, the water consumption for cooling in the distillation process is the largest and reaches 50%, and if the water can be recycled or the consumption is reduced, the water-saving benefit is considerable.
At present, the water-saving measures for the distilled cooling water process are mainly recycled.

The water waste of the existing wine brewing cooling process is a common phenomenon, and the problems of overhigh cooling water temperature, reduced wine yield, thermal pollution and the like caused by the influence of local climate are easily caused. For example, in a famous Erguotou winery in Beijing, tap water is used for cooling, the water drainage temperature is as high as 60-70 ℃, the local environmental protection requirement cannot be met due to too high temperature, the winery has to adopt normal temperature water for cooling to 30 ℃ and then discharge, and the water consumption is doubled. The water discharging temperature of a certain famous strong-flavor liquor in Luzhou, Sichuan is 75 ℃, the liquor is recycled by adopting a cooling tower cooling mode, the temperature of cooling water cannot reach below 30 ℃ in summer and autumn due to hot weather, and the cooling water is an open system, so that strains in a winery are various, the water temperature is suitable for breeding, the cooling tower and a condenser are softened and scaled, and the cooling effect is seriously influenced. A Maotai-flavor liquor of a certain famous Guizhou province is prepared by cooling liquor steam by red river water to generate low-temperature cooling water of 50 ℃ and directly discharging the low-temperature cooling water to a red river to cause thermal pollution of the red river and influence the ecology of the red river. In addition, some wineries adopt an air cooling mode for cooling, and the cooling effect is deteriorated and the wine yield is reduced in hot summer due to higher air temperature.
Therefore, the problems of high water consumption and thermal pollution of the liquor distillation cooling process become important reasons for restricting the development of the liquor industry, and are technical problems to be solved urgently.

Detailed Description
The invention will be described in further detail with reference to the drawings and specific examples.
Example 1
As shown in fig. 1: an unpowered refrigeration cooling circulation system for wine brewing comprises a wine steaming device, a hot water refrigerator, a first buffer tank, a primary cooler, a secondary cooler and a second buffer tank; the wine steaming device comprises a condenser, a water outlet of the condenser is sequentially connected with a first buffer tank, a hot water refrigerator, a primary cooler, a secondary cooler and a second buffer tank through pipelines, and a water outlet of the second buffer tank is connected with a water inlet of the condenser of the wine steaming device through a pipeline to form a cooling circulation system.
Wherein, the cooling water outlet and the cooling water inlet of the hot water refrigerator are respectively connected with the cooling tower through pipelines to form a cooling water circulation system, namely, after the hot water refrigerator exchanges heat with the intermediate temperature water in the first buffer tank, the water heated in the hot water refrigerator enters the cooling tower for exchanging heat, and the cooled water enters the primary cooler. One branch of a cold water outlet of the hot water refrigerator is connected with a spreading cooling machine through a pipeline; the other branch is connected with a secondary cooler through a pipeline. The outlet of the primary cooler is also connected with the water inlet of a grain moistening device for brewing wine, and the inlet of the primary cooler is connected with the water outlet of the grain moistening device for supplementing water. Various circulating systems form a closed system, no scaling risk exists, and the process operation is more stable.
In the wine distilling process, when a water cooling mode is adopted for cooling, the temperature of a cooling water inlet is generally required to be about 22-25 ℃, and the temperature of a condenser is mainly determined by the form of the condenser: the temperature of the effluent of a high-temperature condenser can reach more than 70 ℃; the temperature of the outlet water of the low-temperature condenser is generally lower and is only about 50 ℃. According to different water outlet temperatures, different lithium bromide absorption technologies can be adopted to realize water and energy saving according to customer requirements. The condenser of the wine distilling device of the embodiment is preferably a high-temperature condenser.
The medium-temperature cooling water (more than or equal to 70 ℃) generated by the high-temperature condenser can drive a hot water type lithium bromide absorption refrigerator (a hot water refrigerator for short) to refrigerate, and the higher the temperature of the medium-temperature cooling water is, the higher the refrigerating efficiency of the refrigerator is, and the more the generated refrigerating capacity is. The generated cold energy can be used for cooling by medium-temperature cooling water, and the redundant cold energy can also be used for other refrigeration requirements, such as cooling by a spreading cooler, constant-temperature fermentation workshops, office buildings and other buildings.
The lithium bromide absorption refrigerator is a unit using heat energy to drive lithium bromide solution to make circulation refrigeration. The lithium bromide absorption refrigerator has very low power consumption (about 5 per thousand of refrigerating capacity), and the adopted heat source may be steam (not less than 0.1 MPa), hot water (not less than 70 deg.c), high temperature fume (not less than 300 deg.c), natural gas, marsh gas, etc. and is widely used in various fields. The lithium bromide absorption type refrigerating machine mainly comprises a single-effect unit and a double-effect unit, wherein the refrigerating efficiency (the ratio of refrigerating capacity to heat of a driving heat source) of the single-effect lithium bromide absorption type unit is 0.4-0.8; the refrigerating efficiency of the double-effect lithium bromide absorption type unit is 1.3-1.5. In the wine making industry, single-effect hot water type lithium bromide refrigerators, steam type lithium bromide absorption refrigerators and gas type lithium bromide absorption refrigerators are mainly used. In the embodiment, a hot water type lithium bromide refrigerator, namely a hot water refrigerator is selected, and can be driven by medium-temperature water generated by a high-temperature condenser in a wine distilling device without additionally providing power, so that the defects of the traditional wine brewing distillation cooling process are overcome, the self-cooling circulation of the distillation cooling process is realized, and the water saving rate can reach more than 80%.
The distillation cooling circulation flow comprises the following steps: the low-temperature water with the temperature of 22 ℃ is sent into a condenser of each wine distilling device, the wine steam is condensed into the original wine, and then the low-temperature water is heated to 80 ℃. Since each condenser is operated at a different time and the flow rate of the cooling water is different, the medium temperature cooling water of each condenser is collected into a large first buffer tank. The 80 ℃ medium temperature cooling water in the first buffer tank is conveyed to the hot water refrigerator through the water pump and then cooled to 55 ℃, the 7 ℃ cold water prepared by the hot water refrigerator is conveyed to the secondary cooler to finally cool the medium temperature cooling water to 22 ℃, and the redundant cold energy is used for cooling of the spreading cooler. Cooling water with the temperature of 37 ℃ generated in the refrigeration process is circularly cooled by a cooling tower. The medium temperature cooling water with the temperature of 55 ℃ is cooled to 30 ℃ by a first-stage cooler, and is finally cooled to 22 ℃ by a second-stage cooler and sent to a second buffer tank for recycling. The heat (such as 50 ℃) of the primary cooler can be used for moisturizing and preheating grain moistening water for brewing wine or cooling in an air cooling mode, and moisturizing water at 25 ℃ after grain moistening heat exchange can enter the primary cooler again to form moisturizing circulation. The low-temperature water with the temperature of 22 ℃ in the second buffer tank enters a condenser of the wine distilling device again to form a cooling circulation. The distillation cooling circulation mode is mainly used for cooling circulation in summer.
Example 2
As shown in fig. 2: an unpowered refrigeration cooling circulation system for wine brewing comprises a wine steaming device, a heat exchanger, a first buffer tank, a primary cooler, a lithium bromide absorption heat pump unit and a second buffer tank; the wine distilling device comprises a condenser, and the condenser is a high-temperature condenser. The water outlet of the condenser is sequentially connected with the first buffer tank, the heat exchanger, the primary cooler, the lithium bromide absorption heat pump unit and the second buffer tank through pipelines, and the water outlet of the second buffer tank is connected with the water inlet of the condenser of the wine steaming device through a pipeline to form a cooling circulation system.
Wherein, the hot water outlet and the hot water inlet of the heat exchanger are both connected with the heat supply end to form hot water circulation heating. The outlet of the primary cooler is also connected with the water inlet of a grain moistening device for brewing wine, and the inlet of the primary cooler is connected with the water outlet of the grain moistening device for supplementing water. The lithium bromide absorption heat pump unit is a steam type heat pump, and is driven by steam, and a hot water outlet and a hot water inlet of the steam type heat pump are also connected with a heat supply end to form hot water circulation heating.
The working principle of the embodiment is as follows: when the production workshop and the office area of the northern brewery have heating requirements in winter, the low-grade heat recovery can be realized by combining the steam type lithium bromide absorption heat pump for heating. Conveying the 80 ℃ medium temperature cooling water of the first buffer tank to a heat exchanger through a water pump, and then cooling to 55 ℃; the hot water at 60-70 ℃ generated in the refrigeration process is used for heating, and the heating water at 50 ℃ generated by the heating system enters the heat exchanger to form circulation of the heating water. Cooling the 55 ℃ medium temperature cooling water to 30 ℃ by a primary cooler, and using the heat (such as 50 ℃) of the primary cooler after cooling to preheat grain moistening water; cooling water cooled to 30 ℃ is cooled to 22 ℃ by a steam type heat pump for recycling. The hot water at 60-70 ℃ generated by the steam type heat pump after heat exchange is used for heating, and the heating water at 50 ℃ generated by the heating system enters the steam type heat pump to form circulation of the heating water.
It is understood that the above temperature value is only one preferable value of the present invention, and the present invention is not particularly limited.
The following are two preferred embodiments of the present invention:
sichuan Yibin certain strong aromatic white spirit brewing base produces 2.5 ten thousand tons of raw liquor per year. The brewing workshop has 18 sets of coolers, the inlet and outlet temperature is 20/85 ℃, and the flow rate per hour is 20 t/h. The generated medium-temperature cooling water is directly discharged, so that heat pollution is formed while energy is wasted. In addition, the spreading cooling process adopts an electric refrigerator for refrigeration and cooling, and a large amount of electric energy is consumed. After the cooling process is improved, a hot water type refrigerating machine (refrigerating capacity of 400 kW) of the system is adopted to realize 85/20 ℃ cooling circulation and replace 60% of electric refrigeration of a spreading cooling process. The water is saved by 13 ten thousand tons and the electricity is saved by 36 ten thousand kWh every year.
The former cooling mode of cooling tower adopted by Guangdong Buddha mountain certain winery, the inlet and outlet temperature of the condenser is 32/52 ℃, and the temperature of the cooling water is higher in summer high-temperature and high-humidity weather, which causes the reduction of the wine yield and the prolonging of the wine yield time. After the cooling process is modified into a high-temperature condenser, the temperature of the medium-temperature cooling water reaches 90 ℃, the flow rate is 126t/h, and the nearly 3 ten thousand m of cold energy is realized by preparing 2733kW cold energy by using one hot water type refrigerating machine2The buildings are free to refrigerate, and the annual energy saving cost is 123 ten thousands kWh.
In conclusion, the system not only realizes distillation cooling circulation, but also maximizes the heat supply by utilizing the heat, can effectively reduce the water consumption of the winery, has the water saving rate of over 80 percent, has no scaling risk and more stable process operation because the distillation cooling process is changed from an original open system to a closed system, maximizes the heat utilization rate of the circulating cooling water by combining the refrigeration and heating requirements of the winery, and solves the problem of heat pollution.
