Description
Technical field
The present invention relates to a kind of high efficiency of energy method of comprehensive utilization that data center, distributed energy station and LNG stand that integrates.
Background technology
Natural gas is purifying and ultralow temperature processing from gas-field exploitation process, and volume suddenly contracts 600 times and changes super-low liquid into, forms liquefied natural gas (LNG).Through-162 DEG C of low temperature LNG liquid that purify, liquefaction forms, transport on a large scale global market for natural gas to by cargo ship.But the LNG liquid of low temperature cannot directly use, need to gasify again and change gaseous compressed natural gas (CNG) into and deliver to end user by pipe network.The LNG required heat that gasifies was by providing with marine heat exchange or by the mode of gas-firing supplementary heating in the past.So the cold energy of flood tide is not only by scientific utilization, and destroyed the marine eco-environment and even consumed natural gas resource.At present, China fully payes attention to LNG cold energy use, and near newly-built LNG receiving station, all supporting have devices such as air separation, tire pulverizing, generating, freezer, coal gasification, lighter hydrocarbons separation.But the even running of these devices is subject to the impact of flow system flow fluctuation and pressure larger, cold energy use efficiency is lower.Must find more rational cold energy use mode, improve the added value of cold energy, to reduce the downstream cost of LNG.
Data center is the critical infrastructures of contemporary information systems, and along with the arrival of large data age, scale and the quantity of data center grow at top speed.Show according to ICTresearch consulting firm survey data, China every year newly-built, enlarging data center Area Growth rate surpasses 15%, and newly-increased data center quantity growth rate surpasses 6%.Data center's energy consumption is generally transformed weak electricity system energy consumption five parts such as energy consumption, illuminator and VMC energy consumption and gate inhibition, fire-fighting, cctv surveillance and forms by information technoloy equipment energy consumption, refrigeration system energy consumption, UPS, first three part energy consumption accounts for data center's total energy consumption approximately 95%.Electric energy and cold energy supply highly is reliably the prerequisite of the normal operation of data center, once the machine of delaying will cause that corrupted data is even lost etc. serious consequence.Current, data center's power supply is basic, and taking traditional civil power as main, cooling is substantially taking traditional electric refrigeration modes as main, and this energy-provision way can cause larger burden to external power grid in the time of peak of power consumption; On the other hand, traditional civil power is conventionally taking thermal power generation as main, and thermal power generation efficiency of energy utilization is lower, and carbon emission amount is large, environmental pollution is serious, and, along with the continuous expansion of data center's scale, this energy-provision way will cause the sharply increase of carbon emission amount.
Distributed energy station adopts natural air cooling, CCHP mode, directly user oriented, provide various forms of energy by user's request.It is different from centralized production of energy and the supplying mode of traditional " large unit, high-power station, large electrical network ", but be dispersed in user side, reach more high-energy source utilization rate, the multi-functional target such as lower energy cost, higher function security and better environmental-protecting performance more with Integrated Energy cascade utilization pattern.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of high efficiency of energy utilization system that data center, distributed energy station and LNG stand that integrates.
Another object of the present invention is to provide the operation process of this high efficiency of energy utilization system.
To achieve these goals, the present invention takes following technical scheme:
High efficiency of energy utilization system, comprises data center, distributed energy station and LNG station three large main body facilities; LNG station is connected with distributed energy station, data center, user, provides natural gas to distributed energy station, user, provides cold energy to data center; Data center provides gasification required heat energy to LNG station;
Data center is communicated with outdoor air, and is connected with distributed energy station, civil power, and distributed energy station provides cold energy and electric energy to data center, and civil power provides electric energy to data center, in the time that environment temperature is lower, obtains required cold energy from outdoor.
The operation process of high efficiency of energy utilization system, as follows:
In summer, LNG station, for distributed energy station, user provide natural gas, offers data center by the cold energy of gasification heat transfer process release simultaneously; Distributed energy station natural gas fuel generates electricity as data center provides electric energy, and distributed energy station utilizes the fume afterheat after natural gas fuel to freeze as data center provides cold energy, alleviates the pressure of civil power;
In winter, LNG stands as heating user provides natural gas, the cold energy demand of the cold energy associating outdoor air system security data center that LNG gasification discharges, and now distributed energy station is substantially out of service, and data center provides electric energy by outer net civil power.
Spring, season in autumn, the required cold energy of data center is complemented one another and is provided by distributed energy station and LNG station; Required electric energy can be complemented one another and be provided by distributed energy station and outer net civil power.
The present invention compares with similar technology, has following remarkable advantage:
1, summer peak of power consumption, during with gas low ebb, consume LNG station natural gas, utilize distributed energy station to provide electric energy and cold energy for data center; While using in the winter time gas peak, utilize civil power to power for data center, city's electric & gas is had to dual " peak load shifting " effect.
2, the cold energy of LNG is applied to data center's cooling, has not only improved efficiency of energy utilization, reduced power consumption, and alleviated the negative effect to environment when LNG gasifies.
3, in the winter time, it is cooling that the cold energy associating outdoor air that adopts LNG carries out nature to data center, can greatly reduce data center's cooling energy consumption.
4, system synthesis energy-saving efficiency is greater than 15%.
