Description
Technical Field
The invention relates to the technical field of data center cooling, in particular to the utilization of sewage heat energy.
Background
The servers of the urban data center and the like generate a great deal of heat during the operation process. This large amount of heat can affect the safe and stable operation of devices such as servers. For this reason, city data centers often require the provision of bulky cooling equipment. Although the cooling devices can solve the problem of heat dissipation, the cooling devices are expensive, difficult to arrange and cannot effectively recycle the heat emitted by the urban data center, so that energy waste is caused.
Meanwhile, with the enhancement of environmental protection and energy conservation consciousness of people, the utilization of low-grade heat energy is more and more paid attention to. The low-grade heat energy is waste heat energy which has low grade, small concentration and little energy and is not paid attention to by people.
Cities have a large amount of underutilized low-grade heat energy, such as widely-existing solar energy, geothermal energy and energy in sewage, river water or air, and even in industrial processes such as steel, chemical industry and the like, the low-grade heat energy is generated.
The sewage treatment is an industry with smaller scale in national economy, but belongs to the energy-intensive high-energy consumption industry; it is estimated that the carbon emission in the sewage treatment industry accounts for about 1% -2% of the total carbon emission in the whole society. Meanwhile, the residual heat energy reserve of the sewage is quite abundant, and according to related data, the theoretical heat energy contained in the sewage is 4.64 kW.h/m 3 (the temperature difference is 4 ℃).
Studies have shown that the potential value contained in municipal sewage can reach 9 to 10 times of the sewage treatment energy consumption. Meanwhile, early research conclusions show that chemical energy in urban sewage accounts for about 10% of the total potential value, and 90% of sewage potential is generated by heat. If the heat energy in the sewage is reasonably utilized, the sewage treatment plant can be changed into an 'energy factory' from the original energy-consuming factory, so that the operation can be indirectly realized, and a large amount of carbon transaction amount can be generated.
But the heat energy in the existing sewage is not effectively recycled. This is because the heat extracted from the waste water residual heat energy belongs to low grade energy (40 to 80 ℃), is difficult to use for power generation, can only be directly utilized, and has an effective heat transfer radius of only 3 to 5km.
The existing sewage heat energy utilization method is mainly a centralized utilization method.
The centralized utilization method refers to centralized utilization of heat energy of water discharged from a sewage treatment plant. Because the effluent of the sewage treatment plant has higher latent heat value than the original sewage, the heat energy is relatively easy to be extracted by the water source heat pump system, and the problems of pollution prevention, blockage prevention, corrosion prevention structure and the like of the heat exchanger (heat pump) can be avoided by adopting the method. However, this method has a limited range of heat energy utilization, and has problems of heat loss and transportation cost due to long-distance transportation.

Detailed Description
In order to make the technical scheme and the advantages of the present invention more clear, the following detailed description of the specific embodiments of the present invention will be further described in detail with reference to the accompanying drawings. The various embodiments described below are only a few, but not all, of the preferred embodiments of the present invention; the various embodiments described below are intended to be illustrative of the invention and should not be construed as limiting the invention; reasonable combinations of technical features defined by the various embodiments of the present invention, and all other embodiments that can be obtained by one of ordinary skill in the art without making inventive efforts based on the embodiments of the present invention, are within the scope of protection of the present invention.
In a first embodiment, referring to fig. 1 and 2, the present embodiment provides a heat energy exchange system for a data center and a sewage plant, and the specific implementation contents are as follows:
The system comprises a data center cooling module 1 and a sewage energy storage module 4;
sewage 28 flows through the sewage energy storage module 4;
the sewage energy storage module 4 is connected with the data center cooling module 1 in series to form a cooling loop 17;
A primary heat exchange circulating medium circularly flows in the cooling loop 17;
the primary heat exchange circulating medium is used for absorbing heat of the data center main board 7 to be cooled and transmitting the heat to the sewage 28 in the sewage energy storage module 4.
In this embodiment, the cooling circuit 17 specifically includes the sewage energy storage module 4, the data center cooling module 1, and two branches connected in series between the sewage energy storage module 4 and the data center cooling module 1;
The primary heat exchange circulating medium with the heat of the main board of the data center flows in the branch which is connected in series with the outflow end of the primary heat exchange circulating medium of the cooling module 1 of the data center and the inflow end of the primary heat exchange circulating medium of the sewage energy storage module 4, and the temperature of the primary heat exchange circulating medium is higher, so that the branch can be called as a heat flow branch 17.1 of the cooling loop;
Meanwhile, the branch connected in series between the outflow end of the primary heat exchange circulating medium of the sewage energy storage module 4 and the inflow end of the primary heat exchange circulating medium of the data center cooling module 1 flows through the primary heat exchange circulating medium after the heat of the main board of the data center is exchanged for the sewage 28, and the temperature of the primary heat exchange circulating medium is low, so that the branch can be called as a cold flow branch 17.2 of the cooling loop.
In the embodiment, the data center and the sewage plant are built together, so that the operation and management cost can be saved.
The sewage is adopted to replace a refrigerating system to be used as a cooling source of the data center, so that adverse effects on the environment are avoided, and a large amount of energy consumption can be saved (namely, the PUE value of the data center is reduced).
The PUE, abbreviated Power Usage Effectiveness, is an index for evaluating the energy efficiency of the data center, and is the ratio of all energy consumed by the data center to the energy consumed by the IT load.
PUE = data center total energy consumption/IT equipment energy consumption, where the data center total energy consumption includes IT equipment energy consumption, refrigeration system energy consumption, power supply and distribution system energy consumption, and other energy consumption such as lighting. The PUE, having a value greater than 1, the closer the value is to 1, indicating that the less power is consumed by the non-IT devices, the better the energy efficiency level.
In the traditional data center, the energy consumption ratio of the refrigeration system is the largest (at least accounting for 0.4), and after sewage is adopted to replace the refrigeration system as a cooling source of the data center, the energy consumption of the refrigeration system can be saved; meanwhile, the power supply and distribution system of the data center generally adopts commercial power for supplying power, and the UPS power with energy storage is generally adopted in the sewage plant, after the sewage plant and the data center are built together, the UPS power of the sewage plant can be adopted to replace the power supply and distribution system of the data center, so that the PUE value of the data center is further reduced, and the PUE value of the data center after the data center and the sewage plant are built together can be reduced to below 1.05.
In this embodiment, the sewage energy storage module 4 enriches the heat energy of the main board 7 of the data center to be cooled into the sewage 28 through the cooling loop 17, so that the running temperature of the main board 7 of the data center to be cooled is ensured to be stabilized between 42 and 50 ℃, and the energy grade of the sewage 28 is increased.
The sewage with low energy grade has short heat energy supply conveying distance (smaller heat energy service range), and further has low heat energy utilization efficiency.
The energy grade of the sewage is improved, the conveying distance of the heat energy supply is increased, and the energy utilization rate of the heat energy is further increased.

the phase-change cooling loop 18 is used for circularly flowing a secondary heat exchange circulating medium under a set condition;
the secondary heat exchange circulation medium is used for absorbing heat of the heat flow branch 17.1 of the cooling loop and transferring the heat to the sewage 28 in the sewage energy storage module 4.
Further, a preferred embodiment is provided, wherein the secondary heat exchange circulation medium transfers heat absorbed from the heat flow branch 17.1 of the cooling circuit to the sewage 28 in the sewage energy storage module 4 in a liquid-gas phase change manner;
At this time, the set conditions include a temperature condition and a pressure condition:
Temperature conditions: a secondary heat exchange circulation medium in thermal contact with the hot flow branch 17.1 of the cooling circuit, the temperature of which reaches or exceeds the critical temperature of the liquid-gas phase transition thereof;
pressure conditions: part of the secondary heat exchange circulating medium in thermal contact with the heat flow branch 17.1 of the cooling loop begins to gasify, and the gas pressure of the gasified secondary heat exchange circulating medium reaches or exceeds a set value.
