Description

Technical Field

[0001] The invention relates to the technical field of beer brewing, and in particular to a thermal energy integrated system and method based on an air compressor and a low-temperature zone of a production line sterilizer. Background Art

[0002] In traditional beer brewing production, an air compressor is usually required to heat tap water to steam, and then the steam is used to heat the sterilizer. In this process, the steam passing through the sterilizer will be converted into hot water, and the hot water still has a lot of waste heat, which is often directly discharged into the environment, resulting in energy waste. Therefore, how to effectively recycle and utilize the waste heat of hot water to provide a heat source for the sterilizer has become a problem that needs to be solved urgently. Summary of the invention

[0003] In order to overcome the problems existing in the prior art, the purpose of the present invention is to provide a comprehensive thermal energy system and method based on an air compressor and a low-temperature zone of a production line sterilizer.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a comprehensive thermal energy system based on an air compressor and a low temperature zone of a production line sterilizer, comprising:

[0005] A heating device, a hot water storage tank, a hot water pipe, a cold water pipe, a first heat exchanger, a second heat exchanger, a first sterilizer, and a second sterilizer;

[0006] The water outlet of the heating device is connected to the water inlet of the hot water storage tank, and the water outlet of the hot water storage tank is connected to the hot water inlet of the first heat exchanger and the hot water inlet of the second heat exchanger through the hot water pipe; the cold water outlet of the first heat exchanger and the cold water outlet of the second heat exchanger are connected to the water inlet of the heating device through the cold water pipe;

[0007] The hot water outlet of the first heat exchanger is connected to the water inlet of the first sterilizer, and the water outlet of the first sterilizer is connected to the cold water inlet of the first heat exchanger; the hot water outlet of the second heat exchanger is connected to the water inlet of the second sterilizer, and the water outlet of the second sterilizer is connected to the cold water inlet of the second heat exchanger.

[0008] Main working principle: The heating device starts working, and after heating the water, the hot water flows into the hot water storage tank through the pipe for storage. The hot water stored in the hot water storage tank flows into the hot water inlet of the first heat exchanger and the second heat exchanger through the hot water pipe. In the first heat exchanger and the second heat exchanger, the hot water releases heat and transfers the heat energy to the first sterilizer and the second sterilizer to discharge the cold water flowing through the cold water inlet, so the cold water is heated. The heated cold water (now becomes warm water or hot water) flows out from the hot water outlet of the first heat exchanger and the second heat exchanger, and re-enters the first sterilizer and the second sterilizer. At the same time, the hot water entering from the hot water inlet is converted into cold water due to heat conduction to the cold water in the cold water inlet, and is discharged from the cold water outlet and returned to the water inlet end of the heating device through the cold water pipe for reheating or recycling.

[0009] This process is continuously cycled, allowing the system to efficiently utilize thermal energy. There is no need to heat the first sterilizer and the second sterilizer from room temperature water to hot water every time. In summary, the thermal energy integrated system provides thermal energy through a heating device and uses a heat exchanger to exchange thermal energy, thereby realizing an efficient thermal energy recycling system.

[0010] Preferably, a cold water storage tank is arranged between the cold water outlet of the first heat exchanger, the cold water outlet of the second heat exchanger and the water inlet end of the heating device, and the cold water storage tank and the hot water storage tank are connected to each other, and a valve is provided between the cold water storage tank and the hot water storage tank to control the water flow.

[0011] Preferably, a valve is provided between the cold water storage tank and the hot water storage tank to control the water flow.

[0012] Preferably, the heating device includes an oil-free air compressor and a micro-oil air compressor, the water outlets of the micro-oil air compressor and the oil-free air compressor are connected to the water inlet of the hot water storage tank, and the cold water outlet of the first heat exchanger and the cold water outlet of the second heat exchanger are connected to the water inlet of the micro-oil air compressor and the oil-free air compressor through the cold water pipe.

[0013] Preferably, it further comprises a regulating pipe, both ends of which are respectively connected to the hot water pipe and the cold water pipe, and a valve is provided on the regulating pipe to control the water flow.

[0014] Preferably, the first sterilizer is provided with a plurality of first sterilization tanks, the hot water outlet of the first heat exchanger is connected to the water inlets of the plurality of first sterilization tanks, and the water outlets of the plurality of first sterilization tanks are connected to the cold water inlet of the first heat exchanger;

[0015] The second sterilizer is provided with a plurality of second sterilization tanks, the hot water outlet of the second heat exchanger is connected to the water inlets of the plurality of second sterilization tanks, and the water outlets of the plurality of second sterilization tanks are connected to the cold water inlet of the second heat exchanger.

[0016] A thermal energy integration method based on the low temperature zone of the air compressor and the production line sterilizer is applied to the above-mentioned thermal energy integration system based on the low temperature zone of the air compressor and the production line sterilizer, and the steps are as follows:

[0017] S1. Inject tap water into the heating device for heating;

[0018] S2, the heating device heats the tap water to a specified temperature, and after heating is completed, transmits the hot water to the hot water storage tank through a pipeline;

[0019] S3, the hot water storage tank distributes hot water to the outer tube of the first heat exchanger and the outer tube of the second heat exchanger through the pipeline, and at the same time the first sterilizer and the second sterilizer distribute cold water to the inner tube of the first heat exchanger and the inner tube of the second heat exchanger for heat exchange;

[0020] S4, the cold water in the inner tube of the first heat exchanger and the inner tube of the second heat exchanger is heated and then flows back to the first sterilizer and the second sterilizer through the pipeline. The hot water in the outer tube of the first heat exchanger and the outer tube of the second heat exchanger drops in temperature after heat transfer and flows back to the heating device through the cold water pipe for reheating, thus completing the cycle.

[0021] Preferably, in S2, if too much hot water is stored in the hot water storage tank, the valve between the cold water storage tank and the hot water storage tank is opened, and the hot water in the hot water storage tank overflows through the pipeline into the cold water storage tank for storage.

[0022] Preferably, in S3, the valve in the regulating pipe is opened or closed, and part of the hot water in the hot water pipe flows directly into the cold water pipe along the regulating pipe, thereby adjusting the flow of hot water in the hot water pipe into the first heat exchanger and the second heat exchanger.

[0023] Preferably, in S4, the cold water in the first heat exchanger and the second heat exchanger flows back to the cold water storage tank through the cold water pipe for storage. When the cold water in the cold water storage tank reaches a certain capacity, it is distributed to the heating device for unified heating.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention recycles and utilizes the air compressor to heat the tap water, converts it into the heat energy required by the sterilizer, and recycles the hot water whose temperature drops to reheat it, which significantly improves the utilization efficiency of heat energy and reduces energy consumption. In addition, the system can maintain stable operation under different working conditions through the design of hot water storage tanks and cold water storage tanks, thereby improving the reliability and stability of the system.

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present invention, and the embodiments described are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] Example 1

[0033] This embodiment discloses a heat energy integrated system based on an air compressor and a low temperature zone of a production line sterilizer, such as Figure 1 As shown, it includes a heating device 1, a hot water storage tank 2, a cold water storage tank 3, a hot water pipe 4, a cold water pipe 5, a first heat exchanger 6, a second heat exchanger 7, a first sterilizer 8 and a second sterilizer 9.

[0034] The water outlet of the heating device 1 is connected to the water inlet of the hot water storage tank 2, and the water outlet of the hot water storage tank 2 is connected to the hot water inlet a of the first heat exchanger 6 and the second heat exchanger 7 through the hot water pipe 4. The cold water outlet b of the first heat exchanger 6 and the second heat exchanger 7 is connected to the water inlet of the heating device 1 through the cold water pipe 5.

[0035] The heating device 1 starts to work, and after heating the water, the hot water flows into the hot water storage tank 2 through the pipeline for storage. The hot water stored in the hot water storage tank 2 flows into the hot water inlet a of the first heat exchanger 6 and the second heat exchanger 7 through the hot water pipe 4. In the first heat exchanger 6 and the second heat exchanger 7, the hot water releases heat and transfers the heat energy to the cold water discharged from the first sterilizer 8 and the second sterilizer 9 through the cold water inlet d, and the cold water is heated. The heated cold water (now turned into warm water or hot water) flows out from the hot water outlet c of the first heat exchanger 6 and the second heat exchanger 7, and re-enters the first sterilizer 8 and the second sterilizer 9. At the same time, the hot water entering from the hot water inlet a is converted into cold water due to heat conduction to the cold water in the cold water inlet d, and is discharged from the cold water outlet b and returned to the water inlet end of the heating device 1 through the cold water pipe 5 for reheating or recycling. During the cycle, in order to ensure that the heating device 1 can work continuously and ensure the temperature balance in the first sterilizer 8 and the second sterilizer 9, the hot water storage tank 2 needs to alternately heat the first heat exchanger 6 and the second heat exchanger 7 .

[0036] In some optional embodiments, after hot water enters the first heat exchanger 6 and the second heat exchanger 7 along the hot water pipe 4 from the hot water storage tank 2, heat exchange is performed, and then flows out from the cold water outlet b of the first heat exchanger 6 and the second heat exchanger 7 in the form of cold water, flows into the cold water storage tank 3, and then flows back to the oil-free air compressor and the micro-oil air compressor for reheating or recycling as needed.

[0037] In some optional embodiments, the cold water storage tank 3 and the hot water storage tank 2 are connected to each other and a valve is provided to control the water flow. When there is too much hot water in the hot water storage tank 2, the excess hot water can overflow into the cold water storage tank 3 by opening the valve.

[0038] In some optional embodiments, the heating device 1 includes an oil-free air compressor and a micro-oil air compressor, the water outlets of the micro-oil air compressor and the oil-free air compressor are connected to the water inlet of the hot water storage tank 2, the cold water outlet b of the first heat exchanger 6 and the cold water outlet b of the second heat exchanger 7 are connected to the water inlet of the micro-oil air compressor and the oil-free air compressor through the cold water pipe 5, wherein the oil-free air compressor has precise temperature control and low power consumption, and the micro-oil air compressor has fast heating speed and high power consumption. By utilizing the different characteristics of the two air compressors, when the tap water is initially heated, a higher-power micro-oil air compressor is used to heat the tap water at room temperature into hot water. When the tap water is heated to hot water, the tap water that retains residual heat is subsequently heated to hot water by the oil-free air compressor. This process does not require the tap water to be heated significantly. Through this design, energy consumption can be greatly reduced.

[0039] In some optional embodiments, a mixing pipe 10 is provided in the system, and its two ends are respectively connected to the hot water pipe 4 and the cold water pipe 5, and a valve is provided to control the water flow, so that the ratio of hot water and cold water can be adjusted as needed to meet different heat energy requirements.

[0040] In some optional embodiments, the hot water flowing out of the hot water outlet c of the first heat exchanger 6 enters the multiple first sterilization tanks of the first sterilizer 8, and the first sterilization tanks are heated. The treated water flows out of the water outlet of the first sterilization tank and returns to the cold water inlet d of the first heat exchanger 6; the hot water flowing out of the hot water outlet c of the second heat exchanger 7 enters the multiple second sterilization tanks of the second sterilizer 9, and the first sterilization tanks are heated. The treated water flows out of the water outlet of the second sterilization tank and returns to the cold water inlet d of the second heat exchanger 7.

[0041] Example 2

[0042] This embodiment discloses a thermal energy integration method based on the low temperature zone of the air compressor and the production line sterilizer. The thermal energy integration system based on the low temperature zone of the air compressor and the production line sterilizer is applied. The steps are as follows:

[0043] S1, inject tap water into the heating device 1, and start the heating process, using the waste heat generated by the air compressor as a heat source;

[0044] S2. The heating device 1 heats the tap water to a preset specified temperature.

[0045] After heating is completed, the hot water is safely transmitted to the hot water storage tank 2 through a pipeline for storage.

[0046] If there is too much hot water in the hot water storage tank 2, in order to avoid overflow, the valve between the cold water storage tank 3 and the hot water storage tank 2 can be opened to allow part of the hot water to overflow through the pipeline into the cold water storage tank 3 for temporary storage;

[0047] S3. The hot water in the hot water storage tank 2 is accurately distributed to the outer tubes of the first heat exchanger 6 and the second heat exchanger 7 through the pipeline. At the same time, the first sterilizer 8 and the second sterilizer 9 distribute the cold water to be treated to the inner tubes of the first heat exchanger 6 and the second heat exchanger 7 to exchange heat energy with the hot water efficiently. In this process, the valve in the distribution pipe 10 can be opened or closed according to actual needs to adjust the flow of hot water flowing from the hot water pipe 4 into the first heat exchanger 6 and the second heat exchanger 7, so as to realize flexible distribution of heat energy.

[0048] S4, the cold water in the inner tube of the first heat exchanger 6 and the inner tube of the second heat exchanger 7 is heated and then flows back to the first sterilizer 8 and the second sterilizer 9 through the pipeline. The hot water in the outer tube of the first heat exchanger 6 and the outer tube of the second heat exchanger 7 drops in temperature after heat transfer and flows back to the heating device 1 through the cold water pipe 5 for reheating, thus completing the cycle.

[0049] In some optional embodiments, in S2, if too much hot water is stored in the hot water storage tank 2, the valve between the cold water storage tank 3 and the hot water storage tank 2 is opened, and the hot water in the hot water storage tank 2 overflows through the pipeline into the cold water storage tank 3 for storage.

[0050] In some optional embodiments, in S3, the valve in the regulating pipe 10 is opened or closed, and part of the hot water in the hot water pipe 4 flows directly into the cold water pipe 5 along the regulating pipe 10, and the flow of hot water in the hot water pipe 4 flowing into the first heat exchanger 6 and the second heat exchanger 7 is adjusted.

[0051] In some optional embodiments, S4, the cold water in the first heat exchanger 6 and the second heat exchanger 7 flows back to the cold water storage tank 3 through the cold water pipe 5 for storage. When the cold water in the cold water storage tank 3 is stored to a certain capacity, it is distributed to the heating device 1 for uniform heating.

[0052] In summary, this embodiment achieves efficient recovery and reuse of waste heat from air compressors through an ingenious thermal energy comprehensive method. This innovative solution has significant advantages in improving thermal energy utilization, reducing energy consumption, and improving the overall economic and environmental benefits of the system.

[0053] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
