Example 1
As shown in fig. 1: an unpowered self-cooling circulation system for brewing wine comprises a lithium bromide absorption type unit, a water-water heat exchanger, a first buffer tank, a second buffer tank and a wine steaming device.
In this embodiment, the wine distilling apparatus includes a condenser for condensing wine vapor generated in the distillation process of the wine industry to obtain raw wine. The water outlet of the condenser of the wine steaming device is sequentially connected with a first buffer tank and a lithium bromide absorption type unit through pipelines, the water outlet and the water return port of the lithium bromide absorption type unit are both connected with a water-water heat exchanger, the lithium bromide absorption type unit is further connected with a second buffer tank through a pipeline, 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 self-cooling circulation system.
The lithium bromide absorption type unit and the water-water heat exchanger are also connected with a cooling tower pipeline to form a cooling water circulation system, namely medium-temperature water in the first buffer tank enters a generator of the lithium bromide absorption type unit to drive the unit to operate and then enters the water-water heat exchanger to be further cooled; and the cooled water in the water-water heat exchanger enters an evaporator of the lithium bromide absorption type unit for cooling, and finally the cooled water enters a second buffer tank. The heat from the medium-temperature water to the low-temperature water is respectively cooled by the lithium bromide absorption type unit and the cooling water of the water-water heat exchanger and then discharged by the cooling tower. It will be appreciated that the water cooling of the cooling tower may be replaced by air cooling.
In general, a plurality of wine distilling devices are arranged in a wine brewing workshop, and medium-temperature cooling water generated by a condenser of each wine distilling device is collected and converged into a first buffer tank. The first buffer tank is mainly used for storing medium-temperature cooling water, and the second buffer tank is used for storing low-temperature cooling water. The first buffer tank and the second buffer tank may be provided for each condenser of the wine distilling apparatus, may share one first buffer tank and one second buffer tank with a plurality of condensers, may be provided for each condenser of one condenser, and the like. The condenser of the wine distilling device in the embodiment is a high-temperature condenser.
In this embodiment, the lithium bromide absorption heat exchanger unit is preferably a hot water type lithium bromide absorption heat exchanger unit. The hot water type lithium bromide absorption unit is driven by medium-temperature cooling water, and simultaneously cools the medium-temperature cooling water to low temperature, and the hot water type lithium bromide absorption unit is equivalent to a heat exchanger: the heat of the medium-temperature hot water for temperature reduction (such as 70/22 ℃) is finally discharged in the form of cooling water (such as 30/37 ℃) through a cooling tower. The biggest difference between the hot water type lithium bromide absorption unit and the heat exchanger is that: the outlet temperature of the medium temperature hot water (e.g. 22 ℃) is lower than the inlet temperature of the cooling water (e.g. 30 ℃), which is impossible to achieve by the heat exchanger. Just because this kind of characteristic of hot water type lithium bromide absorption formula unit matches with making wine cooling process parameter, make the cooling process self-cooling circulation realize.
The working principle of the embodiment is as follows: 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 70 ℃. Since the operation time and the cooling water flow rate of each condenser are inconsistent, the medium-temperature cooling water of each condenser is firstly collected into the first buffer tank for buffering. Then the medium temperature cooling water is conveyed into a hot water type lithium bromide absorption type unit through a water pump, heat exchange is carried out between the medium temperature cooling water and the cooling water at 32 ℃ from a water-water heat exchanger, the medium temperature water at 70 ℃ is cooled to 22 ℃ and enters a second buffer tank, and the cooling water at 32 ℃ is heated to 55 ℃ and enters the water-water heat exchanger again for circulation. The heat from the medium-temperature water to the low-temperature water is respectively cooled by the lithium bromide absorption type unit and the cooling water of the water-water heat exchanger and then discharged by the cooling tower. The low-temperature water with the temperature of 22 ℃ is collected in a second buffer tank and finally conveyed back to a condenser of the wine distilling device through a water pump to form circulation.
In the system, the hot water type lithium bromide absorption unit is driven by medium temperature water with the temperature of 70 ℃ without additionally providing power, so that the defects of the traditional 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%. And the heat of the intermediate temperature water (70/22 ℃) is finally radiated and discharged to the environment (or water supplement is preheated and recycled) through the cooling tower by the cooling water of 37 ℃, and energy conservation and environmental protection can be realized by recycling the heat by adopting the cooling tower for cooling.
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 is a preferred embodiment of the present invention:
the system is firstly applied to a famous Erguotou winery in Beijing. The original cooling system of the winery generates medium-temperature cooling water 63t at 70 ℃ per hour, and can not be directly discharged due to the requirement of environmental protection, so that the temperature is reduced to below 30 ℃ by adopting a cold water mixing cooling mode, the daily water consumption of a workshop reaches 1500t, the water resource waste is caused, and the load of a sewage treatment plant is also increased. After the unpowered self-cooling system with the improved cost is adopted, the self-circulation cooling at 70/22 ℃ is realized, the evaporative cooling is adopted to replace the cooling, the water consumption is saved by 1130t every day, and the water saving rate exceeds 90%.
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.
Therefore, the system has good effect on the wine brewing industry.
Example 2
As shown in fig. 2: the difference from embodiment 1 is that the water-water heat exchanger is not connected to the cooling tower, but to the water replenishing system, and this structure is suitable for the case where there is a demand for hot water in the process. Namely, medium temperature water with the temperature of 55 ℃ in a water-water heat exchanger exchanges heat with cooling water with the temperature of 20 ℃ from a water supplementing system, and then the temperature of the medium temperature water is reduced to 32 ℃ and the medium temperature water enters a lithium bromide absorption type unit; and the cooling water with the temperature of 20 ℃ absorbs heat, then is heated to 53 ℃ and enters a water supplementing system to form low-temperature water supplementing preheating circulation for preheating and supplementing water, and the obtained supplemented water can be used for similar purposes such as brewing grain moistening water, boiler water supplementing and the like.
Example 3
As shown in fig. 2: the difference from the embodiment 1 is that the water outlet of the first buffer tank is also connected with a water supplementing heat exchanger, and the water outlet of the water supplementing heat exchanger is connected to a pipeline between the lithium bromide absorption type unit and the second buffer tank; the water supplementing heat exchanger is also connected with a water supplementing system. Part of the medium temperature water with the temperature of 70 ℃ in the first buffer tank enters a hot water type lithium bromide absorption unit and exchanges heat with the cooling water with the temperature of 32 ℃ from a water-water heat exchanger; the other part of the water enters a water supplementing heat exchanger, exchanges heat with cooling water with the temperature of 20 ℃ from a water supplementing system, and then is cooled to the temperature of 25 ℃ to enter a second buffer tank; and the cooling water at the temperature of 20 ℃ absorbs heat and then is heated to 65 ℃ to enter a water supplementing system to form a medium-temperature water supplementing preheating cycle for providing water supplement at a higher temperature.
On one hand, the water supplementing heat exchanger can provide water supplement at higher temperature and improve the utilization rate of medium-temperature cooling water; on the other hand, through setting up moisturizing heat exchanger and water-water heat exchanger, can reach heat balance.
