TECHNICAL FIELD

[0001] The utility model relates to fermentation technical field especially relates to a fermentation system based on data center waste heat utilization. BACKGROUND

[0002] In the fermentation process, the appropriate fermentation conditions for maintaining the growth of production bacteria and product synthesis are required, one of which is temperature. Temperature is an important condition for ensuring enzyme activity, and the growth of microorganisms and product synthesis need to be carried out at their respective suitable temperatures. Therefore, it is necessary to ensure a stable and optimal temperature environment during the fermentation process. Fermentation in a fermentation tank can be divided into three temperature ranges: 50-65 DEG C is called high-temperature fermentation, for example, the fermentation of pickles needs to be carried out at high temperature, so that microorganisms can metabolize faster to produce sour and spicy flavors. 20-45 DEG C is called medium-temperature fermentation, for example, the fermentation of beer needs to be carried out at medium temperature, so that yeast can ferment alcohol and carbon dioxide faster. 20 DEG C or below is called low-temperature fermentation, for example, the fermentation of yogurt needs to be carried out at low temperature to maintain the growth of organisms and the taste of yogurt.

[0003] Generally speaking, the change of temperature affects the fermentation process in two aspects: on the one hand, it affects the fermentation process by affecting the growth and reproduction of production bacteria and the synthesis of metabolic products; on the other hand, it affects the kinetic characteristics of fermentation and the biosynthesis of products by affecting the physical properties of the fermentation broth (such as the viscosity of the fermentation broth, the solubility and transfer rate of the substrate and oxygen in the fermentation broth, etc.). The main methods for heating the fermentation tank are electric heating film heating, solar heating, fossil fuel combustion heating and geothermal heating, but electric heating film heating consumes high-grade electricity; solar heating is greatly affected by weather; fossil fuel combustion has low energy utilization rate and pollution emission; geothermal heating is limited by geological conditions and has limited scope of application. Therefore, it is very important to control the fermentation temperature of the fermentation tank within the appropriate range by using appropriate heating methods.

[0004] In the construction of a data center, due to the arrangement of a large number of cabinets and other hardware devices, as well as the laying of a large number of cables, the internal temperature of the data center is relatively high when in use, which may affect the operation of the equipment in the data center. In order to reduce the temperature in the data center room, a refrigeration system is generally arranged in the data center room to reduce the temperature in the data center. Common refrigeration modes include air conditioning refrigeration mode or liquid cooling mode. Among them, the data center liquid cooling system can capture heat flow near the CPU and other parts, and the waste heat temperature can reach 60-75 DEG C. Since the data center is generally large in scale and needs to operate continuously, the waste heat generated by the equipment has the characteristics of relatively stable heat and large heat output. Direct discharge of the waste heat water generated by the above-mentioned liquid cooling mode needs to be cooled before being recycled to the data center, which not only wastes heat energy but also increases the workload of subsequent cooling treatment.

[0005] Based on the above data center preheating waste problem and fermentation system needs heating problem, it is necessary to design a new cooling and heating system which can solve the above two problems. The utility model discloses a kind of fermentation systems based on data center waste heat utilization, to solve the technical problem that the waste heat of data center is reused and fermentation pool is heated.

DETAILED DESCRIPTION

[0025] In order to make the content of the utility model more easily understood clearly, the utility model is further described in detail below according to specific implementation examples and in combination with the drawings.

[0026] Please refer toFigure 1 and Figure 2 As shown in the figure, the embodiment provides a fermentation system based on data center waste heat utilization, which comprises a fermentation pool heat exchange group, a fermentation pool heat supply adjustment group and a data center cooling group used in cooperation. The three form a cooperation structure of water circulation flow, so that the water containing waste heat formed by the cooling of the data center 1 can be used to heat the fermentation pool, and the fermentation pool heat supply adjustment group adjusts the temperature of the water containing waste heat, so that the waste heat water after temperature adjustment can be applied to the fermentation pool heat supply of different temperature zones.

[0027] Next, in detail, first, the fermentation pool heat exchange group comprises high-temperature fermentation pool 12, medium-temperature fermentation pool 9 and low-temperature fermentation pool 6 arranged side by side. The high-temperature fermentation pool 12, the medium-temperature fermentation pool 9 and the low-temperature fermentation pool 6 here each have a heat exchange cavity suitable for water flow. When water with temperature passes through the heat exchange cavity, the high-temperature fermentation pool 12, the medium-temperature fermentation pool 9 and the low-temperature fermentation pool 6 are heated, and at the same time, the water with temperature is cooled to become normal temperature water.

[0028] Secondly, the fermentation pool heat supply adjustment group comprises high-temperature liquid buffer tank 11, medium-temperature liquid buffer tank 8 and low-temperature liquid buffer tank 5 arranged side by side; the water outlet of the high-temperature liquid buffer tank 11 is connected with the high-temperature fermentation pool 12, the water outlet of the medium-temperature liquid buffer tank 8 is connected with the medium-temperature fermentation pool 9, and the water outlet of the low-temperature liquid buffer tank 5 is connected with the water inlet of the low-temperature fermentation pool 6. The high-temperature liquid buffer tank 11, the medium-temperature liquid buffer tank 8 and the low-temperature liquid buffer tank 5 here each realize temperature adjustment of the water to be passed into the high-temperature fermentation pool 12, the medium-temperature fermentation pool 9 and the low-temperature fermentation pool 6 for heat exchange, so that the water temperature in the heat exchange cavity of the fermentation pool can reach a suitable temperature.

[0029] Finally, the data center cooling group comprises a first water storage tank 13 connected with the data center 1 through a water inlet pipeline and a second water storage tank 3 connected with the data center 1 through a drainage pipeline; the water inlet of the first water storage tank 13 is also connected with the water outlets of the high-temperature fermentation pool 12, the medium-temperature fermentation pool 9 and the low-temperature fermentation pool 6, and the water outlet of the second water storage tank 3 is also connected with the water inlets of the high-temperature liquid buffer tank 11, the medium-temperature liquid buffer tank 8 and the low-temperature liquid buffer tank 5. The first water storage tank 13 and the second water storage tank 3 are each provided with a second temperature sensor and a second liquid level meter. A second water pump 2 is also arranged on the drainage pipeline between the second water storage tank 3 and the data center 1.

[0030] In this structure, it can be understood that the high-temperature fermentation tank 12 cooperates with the high-temperature liquid buffer tank 11 to form a first branch connected with the first water storage tank 13 and the second water storage tank 3, the medium-temperature fermentation tank 9 cooperates with the medium-temperature liquid buffer tank 8 to form a second branch connected with the first water storage tank 13 and the second water storage tank 3, and the low-temperature fermentation tank 6 cooperates with the low-temperature liquid buffer tank 5 to form a third branch connected with the first water storage tank 13 and the second water storage tank 3, and the above three branches form a parallel structure, independent of each other and without interference. In addition, the high-temperature liquid buffer tank 11, the medium-temperature liquid buffer tank 8, the low-temperature liquid buffer tank 5, and the second water storage tank 3 involved in the embodiment are preferably made of a material with heat preservation performance.

[0031] On the basis of the above structure, the first water valve 10 is arranged between the second water storage tank 3 and the high-temperature liquid buffer tank 11, the second water valve 7 is arranged between the second water storage tank 3 and the medium-temperature liquid buffer tank 8, and the third water valve 4 is arranged between the second water storage tank 3 and the low-temperature liquid buffer tank 5.

[0032] In addition, in order to facilitate the control of the amount and temperature of the water in the liquid buffer tank, the high-temperature liquid buffer tank 11, the medium-temperature liquid buffer tank 8, and the low-temperature liquid buffer tank 5 are respectively provided with a first temperature sensor. The high-temperature liquid buffer tank 11, the medium-temperature liquid buffer tank 8, and the low-temperature liquid buffer tank 5 are respectively provided with a first liquid level meter.

[0033] Since the high-temperature water in the second water storage tank 3 needs to be adjusted in temperature by neutralization with normal-temperature water after entering the different buffer tanks, the sum of the volumes of the high-temperature liquid buffer tank 11, the medium-temperature liquid buffer tank 8, and the low-temperature liquid buffer tank 5 is greater than the volume of the second water storage tank 3, so that normal-temperature water can also be introduced into the high-temperature liquid buffer tank 11, the medium-temperature liquid buffer tank 8, and the low-temperature liquid buffer tank 5. For the normal-temperature water introduced into each liquid buffer tank, it can come from the first water storage tank 13, and of course it can also be normal-temperature water externally connected. In this embodiment, the first water storage tank 13 is taken as an example, and the high-temperature liquid buffer tank 11, the medium-temperature liquid buffer tank 8, and the low-temperature liquid buffer tank 5 are also respectively connected with the first water storage tank 13 through a branch, and a first water pump is arranged on each corresponding branch.

[0034] In summary, for the fermentation system based on the waste heat utilization of the data center of the embodiment, the normal temperature water is stored in the first water storage tank 13, which can be introduced into the data center 1 through the water inlet pipeline to cool the data center 1, and in the cooling process, the normal temperature water will become high temperature water due to heating, at this time, the high temperature water will enter the second water storage tank 3 through the drain pipeline, so that the waste heat generated by the cooling of the data center 1 is recycled. The high temperature water in the second water storage tank 3 is divided into three paths and enters the high temperature liquid buffer tank 11, the medium temperature liquid buffer tank 8 and the low temperature liquid buffer tank 5, at this time, the liquid temperatures in the three buffer tanks are the same, but since the heating temperatures required by the high temperature fermentation tank 12, the medium temperature fermentation tank 9 and the low temperature fermentation tank 6 are different, it is necessary to adjust the water temperature in the heat exchange cavity of the high temperature fermentation tank 12, the medium temperature fermentation tank 9 and the low temperature fermentation tank 6, at this time, the first temperature sensor arranged in the high temperature liquid buffer tank 11, the medium temperature liquid buffer tank 8 and the low temperature liquid buffer tank 5 is used to measure the water temperature, and then the normal temperature water is introduced into the high temperature liquid buffer tank 11, the medium temperature liquid buffer tank 8 and the low temperature liquid buffer tank 5 from the first water storage tank 13, so as to neutralize the high temperature water in the high temperature liquid buffer tank 11, the medium temperature liquid buffer tank 8 and the low temperature liquid buffer tank 5, so that the water temperature gradually reaches a suitable temperature, and when the water temperature reaches a suitable temperature, the corresponding fermentation tank is introduced into the heat exchange cavity of the corresponding fermentation tank to heat the fermentation tank, and the water that has completed heat exchange is returned to the first water storage tank 13, so that the circulation of the water is completed, and the purpose of using the waste heat recycled by the data center 1 to provide heat for the fermentation tanks in different temperature zones is achieved.
