Description

Based on the thermoelectric cold triple supply system of heat pump techniques and compressed air electric power storage technology

Technical field

The invention belongs to field of energy utilization, relate to a kind of thermoelectric cold triple supply system based on compressed air accumulate and waste heat utilization technology and method, be particularly useful for thermal source area more in short supply or electrical network peak-valley difference larger area.

Background technology

In China's electrical network, the unit of suitable vast scale is cogeneration units, in order to ensure heat demand, these units adopt the mode of " electricity determining by heat " to run, the regulating power of electrical network is caused to reduce, cause surplus and the waste of a large amount of generating capacity in the electricity needs low ebb phase, have to again in the brownout of peak of power consumption period in electricity needs peak period.Simultaneously due to wind-powered electricity generation; the output power of power supply of solar energy power generating has randomness; fluctuation range is large; change is frequent; cause producing great impact to electrical network during its input electrical network; in order to protect the safe and reliable of bulk power grid, a lot of local online to wind-power electricity generation and solar energy power generating limits, the serious application hindering new forms of energy.Compressed air power storage system receives providing auxiliary power ability because it has in the electric load demand low ebb phase, peak period is to the ability of electrical network feed, and unstable to wind-powered electricity generation and photovoltaic generation etc. supply of electric power is assembled storage on a large scale for a long time, then it is inputted the ability of electrical network with the power of specifying, solve the difficult problem that wind-powered electricity generation etc. impacts electrical network, be therefore with a wide range of applications.

The operation principle of compressed air power storage system is as follows: when energy storage, by compressor by the state of air from the state boil down to HTHP of normal temperature and pressure, is stored in air accumulator, consumes electric power in this process.When exoergic, high compression air flows out from air accumulator, and promote decompressor acting, become the air of normal pressure, compressed-air actuated pressure energy is converted into output mechanical energy and exports by decompressor, and changes mechanical energy is that electric energy inputs to electrical network by driving electric machine.

Be converted to mechanical energy storage because compressed air electricity storage technology comprises electric energy, then be multiple conversion process of energy such as electric energy by changes mechanical energy, a large amount of heat energy can be produced.The compression process that usual air is compressed into high-pressure gas state (5-20MPa) from atmospheric environment can adopt the mode of multi-stage compression, in air compressing process, a large amount of used heat can be produced, compressor exhaust temperature can be higher, needs to arrange interstage cooler to reduce the gas temperature entering next stage compressor at some inter-stages of compression to improve compression efficiency.And in order to improve expansion efficiency in air expansion process, need to carry out preheating to air, therefore compressed air power storage system can reclaim compression produce used heat store, for expansion time preheating.But due to the irreversibility of process and loss, still then produce a large amount of used heat and exist.The energy conversion efficiency (electricity of output is divided by the electricity inputted) of compressed air power storage system is generally between 35%-65% in the world at present, all the other electric energy are converted to the waste thermal energy of different grade, also do not have good utilization ways at present for this part waste thermal energy.

Simultaneously comprise cogeneration heat in the more efficient mode of the northern area of China central heating, water () mode such as source heat pump heat supply.Along with the development in city and banning of coal-burning boiler, thermoelectricity co-generating heat supplying heat breach is increasing.Water () source heat pump heat supply is the important supplement of cogeneration of heat and power, but () source heat pump heat supply is higher for Geological Condition Requirement, the place application that can only be applicable in condition.The larger area of some electrical power peak-valley difference is adopting the mode of low ebb phase electric boiler heat supply, and high-grade electric energy is directly converted to low-grade heat energy by this mode, and energy utilization efficiency is lower, and heat cost is higher.

Therefore recycle a large amount of used heat produced in compressed air accumulate process and carry out heat supply or cooling, not only increase energy conversion efficiency, and heat cost is lower, specific demand is not had to environment, be with a wide range of applications.

A large amount of used heat is produced in compressed air process, these temperature of waste heat are higher, such as, the water temperature of typical inter-stage preheater outlet is generally 115 DEG C, and water temperature needed for heat supply is generally 60 DEG C, directly the water that inter-stage preheater exports is used for the temperature drop 115 DEG C to 65 DEG C (heat transfer temperature differences of 5 DEG C) for heat energy utilization, totally 50 DEG C of temperature drops, the cooling water of 65 DEG C also needs could be used for compressed-air actuated cascade EDFA by the further radiating and cooling to 30 of the modes such as cooling tower DEG C (limiting by an environment temperature/humidity) left and right, and the coolant water temperature of about 30 DEG C is still higher.Therefore these used heat heat supplies are directly adopted can to cause a large amount of energy wastes.

Summary of the invention
