Description

TECHNICAL FIELD

[0001] The utility model belongs to beer brewing production line technical field, more particularly to a multilevel energy closed loop system. BACKGROUND

[0002] At present, the hot water produced by the steam pipeline drain valve is mostly maintained at 88 DEG C and above, and most of this part of hot water is directly discharged to sewage. The collected surplus hot water in the brewing workshop is also discharged to sewage after being used once, which cannot achieve closed loop utilization, and the recovered hot water of brewing will be surplus, which causes a large amount of heat loss, increases the steam consumption and fresh water resource consumption of the company, and leads to the increase of the cost of the company. There are the following two problems:

[0003] First, the existing factory directly discharges the surplus part of hot water to sewage, which not only causes waste of heat energy, but also needs more energy to cool the wastewater to meet the treatment requirements, which increases power consumption. Special chemicals may be needed to adjust the temperature or pH value of the water when treating hot water, which may increase the amount of chemicals used and thus increase the cost of chemicals. Hot water may be more prone to form sludge due to high temperature, which may require more sludge treatment and disposal work. Therefore, the cost of sludge treatment and disposal may be higher when treating hot water

[0004] Second, the existing surplus hot water is directly discharged to sewage after being recovered and used once, which cannot achieve closed loop utilization. The hot water used in the first stage is discharged after being simply used, and the hot water at this time is still rich in heat energy, and part of the recovered hot water is too high in temperature to be directly used in the workshop.

[0039] Specifically, the second sterilization machine 2 comprises a second hot water tank 20 and a second recovery water tank 21.

[0045] Specifically, it also includes the pipeline connecting the heat balance system, the recovered water system, the filling bottle line workshop and the filling can line workshop

[0046] The specific operation principle of the structure of the embodiment is as follows:

[0047] According to the actual production needs, the first sterilization machine 1 is a 36,000-line sterilization machine, the second sterilization machine 2 is a 50,000-line sterilization machine, the third sterilization machine 10 is a 72,000-line sterilization machine, the first double-end machine 6 is a 36,000-line double-end machine, the second double-end machine 7 is a 50,000-line double-end machine, and the first pre-washing bottle machine 8 and the second pre-washing bottle machine 9 are both 50,000-line washing bottle machines;

[0048] The high-temperature condensed water flowing to the filling bottle line workshop has three uses:

[0049] The first use is to send the high-temperature condensed water from the balance pump device 24 of the high-temperature condensed water tank 11 to the wine machine 3 for use.

[0050] The second use is to supplement the high-temperature condensed water from the high-temperature condensed water tank 11 to each alkali pool of the first pre-washing bottle machine 8, the second pre-washing bottle machine 9, the first double-end machine 6 and the second double-end machine 7 before production starts, for new slotting in production start.

[0051] The third use is to send the high-temperature condensed water from the high-temperature condensed water tank 11 to the first heat exchanger 4 of the first double-end machine 6 to perform heat exchange, realize primary heat exchange, and reduce the temperature of the exchanged condensed water to 80-83℃. When heat exchange is not needed, the condensed water is sent to the second heat exchanger 5 of the second double-end machine 7 to perform heat exchange, realize secondary heat exchange, and reduce the temperature to 70-75℃. When heat exchange is not needed, the condensed water is sent to the first sterilization machine 1 and the second sterilization machine 2 through a bypass pipe to perform tertiary heat exchange.

[0052] The tertiary heat exchange is as follows:

[0053] 1. When the 36,000-line sterilization machine and the 50,000-line sterilization machine both produce ordinary beer:

[0054] The condensed water after secondary heat exchange is sent to the hot water tank of the two-line sterilization machine for tertiary heat exchange, the temperature of the exchanged condensed water is reduced to 60-65℃, and finally recovered to the outdoor medium-temperature condensed water tank 12. When the sterilization machine does not need heat exchange, the condensed water is directly recovered to the outdoor medium-temperature condensed water tank 12 through bypass control, to ensure smooth flow of the entire hot water system and to ensure the necessary heat exchange needs of the process flow.

[0055] 2. When the 36,000-line produces ordinary beer and the 50,000-line produces pure beer:

[0056] The condensed water after the secondary heat exchange is separately sent to the hot water tank of the 36,000-can sterilization machine for the third heat exchange. Similarly, when the sterilization machine does not need heat exchange, it is directly recycled to the outdoor medium-temperature condensed water tank 12 through the bypass control, ensuring smooth circulation of the entire hot water system and ensuring the necessary heat exchange needs of the process.

[0057] 3. When the 720,000-can can line is produced:

[0058] The medium-temperature condensed water at 60-65°C is sent from the medium-temperature condensed water tank 12 to the hot water tank of the 720,000-can sterilization machine for the last heat exchange, and then enters the recycling water tank of the sterilization machine for recycling. When the sterilization machine does not need heat exchange, the constant pressure pump at the medium-temperature condensed water tank 12 is closed, the heat exchange is stopped to ensure the production process temperature of the sterilization machine, and the medium-temperature water system waits for the heat exchange needs to automatically start the system. The recycling water tank recycles the condensed water to the outdoor recycling water tank to the maximum extent, and the excess part that cannot be recycled is overflowed and discharged to the ground.

[0059] In the recycling water system, the overflow water of the bottling bottle line workshop and the bottling can line workshop is recycled and sent to the first recycling water tank 13 and the second recycling water tank 14 outdoors, and the recycling water of the fire pool 16 is used for cooling the condenser 17 of the cold station.

[0060] All the recycling water is finally recycled to the first recycling water tank 13, the second recycling water tank 14 and the fire pool 16 for storage.

[0061] The water in the first recycling water tank 13 and the second recycling water tank 14 has two use modes: one is to continuously supply the bottle sorting machine 25 of the bottling bottle line workshop for production; the second is to pump to the water point of each device for device washing when each pre-washing bottle machine, double-end machine and sterilization machine are washed.

[0062] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any modification, equivalent change and modification of the above embodiment according to the technical essence of the present application, without departing from the technical solution of the present application, still belongs to the scope of the technical solution of the present application.
