Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art's every other embodiment obtained, all belongs to
In the range of the utility model protection.
It will be understood by those skilled in the art that in the exposure of the utility model, term " longitudinal direction ", " transverse direction ", "upper",
The orientation of the instructions such as "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom" "inner", "outside" or position are closed
System is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of describing the present invention and simplifying the description, without
It is that the device of indication or suggestion meaning or element must have a particular orientation, be constructed and operated in a specific orientation, therefore on
Stating term should not be understood as limiting the present invention.
It is understood that term " one " is interpreted as " at least one " or " one or more ", i.e., in one embodiment,
The quantity of one element can be one, and in a further embodiment, the quantity of the element can be it is multiple, term " one " is no
It can be interpreted as the limitation to quantity.
For example, some steam power plant uses 3 130 ton/hours (2 is standby with 1) superhigh temperature super-pressure recirculating fluidized bed pots
Furnace matches 2 back pressure types, 15 megawatts of Steam Turbines.Maximum heat range of heat is 15 kilometers, is mainly that 0.6-1.0 megapascal is full with heat request
And steam, the fluctuation of part heat user thermic load are larger.If turbine discharge parameter is excessively high, when thermic load is lower, waste of steam；If
Steam discharge parameter is too low, then pipe network end steam quality cannot be guaranteed.Power plant exports heating parameter：1.6 megapascal, 300 degrees Celsius,
Maximum heat capacity is about 180 ton/hours.
Therefore, in order to guarantee to remain unchanged in the total heating demand of steam power plant, after the thermic load needed for heat user reduces, it is not necessary to
Reduce thermoelectricity unit and export total heat duties, extra thermic load can be introduced the work done of end turbine expansion, thermoelectricity unit is maintained to begin
It is maintained at optimum load operation eventually, improves unit economy.Since steam utilization apparatus is added in end, heat-net-pipeline flow is kept
Always near design discharge, every kilometer of temperature drop and pressure drop are reduced, heat range of heat can be promoted and prevents heat supply pipeline end from steaming
Vapour quality is not up to standard.
As shown in Figure 1, a kind of end steam quality guarantee based on compressed air energy storage technology described in the present embodiment

Mainly as the moisturizing of recirculated water in residual neat recovering system, to make up the consumption of recirculated water in whole system and recycle part
Waste heat, this measure are also to have accomplished to recycle available resource as far as possible.
It is noted that the compressor 3 also has two branches, a branch is compressed air needed for direct be connected to
User, demand is also very huge to compressed air in the market.
In other words, when compressed air demand in the market is big, we can pass through steam turbine by this system
The compressed air that 2 dragging compressors 3 obtain directly feeds user, when demand is little, can use compressed-air energy storage system
System stores air, i.e., the compressed air that compressor 3 generates stores by the second heat exchanger 9 and arrives caisson 7, wherein
To illustrate that the caisson 7 is air reservoir, but it should be noted that be necessary for closed space, when market demand again
It is secondary when becoming larger, the compressed air in storage device can be supplied user again, certainly, also there is another way, even if from storage
The output end output compressed air of device makes expanding machine 4 work using third heat exchanger 10, swollen using compressed air
Exporting mechanical work when swollen decompression outward makes the principle of gas temperature reduction to obtain energy, then generator is driven to be sent out
Electricity resupplies electricity consumption user.
In addition, in the actual operation process, the energy is consumed always in fact, therefore more satisfactory in order to reach
Working condition, the residual neat recovering system in the steam quality safeguards system is primarily to sufficiently recycle thermal energy, and it is cold to carry out heat
Medium circulation.
Specifically, the residual neat recovering system includes high-temperature medium storage tank 5, cryogenic media storage tank 6, heat-exchanger pump 11 and cold
The output end of water pump 12, the First Heat Exchanger 8 is connect with the first input end of high-temperature medium storage tank 5, at this time 2 row of steam turbine
Vapour has been fed to high-temperature medium storage tank 5 after 8 recovery waste heat of First Heat Exchanger, for the moisturizing of recirculated water, the height
The output end of warm medium reservoirs 5 is connect by heat-exchanger pump 11 with the input terminal of the third heat exchanger 10, the third heat exchanger
10 output end is connect with the input terminal of cryogenic media storage tank 6, and by the transmission of heat-exchanger pump 11, high-temperature medium is transported to low temperature
Medium reservoirs 6, high-temperature medium enter cryogenic media storage tank 6, similarly, cryogenic media after releasing heat by third heat exchanger 10
Storage tank 6 enters high-temperature medium storage tank 5 by 12 transporting low temperature medium of water supply pump after heat absorption, to accomplish the circulation benefit of resource
With.
In some embodiments, steam quality safeguards system is set in central heating steam pipe network end, to adapt to low-heat
Load condition guarantees Operational Economics in Thermal Power Plant and end steam quality.
In some embodiments, a wherein branch for the output end of the steam turbine 2 passes through shaft coupling and the compression
The input terminal of 3 input shaft of machine connects, and the axis connection of steam turbine (2) and compressor 3 is realized synchronization to together by shaft coupling
Work.
In some embodiments, the branch turnoff of the compressor 3 is equipped with valve, this valve is in control piper
The direction of fluid accomplishes to make full use of resource.
In some embodiments, the compressor 3 is back pressure type steam-operating compressor 3, relative to motor compressor 3
Speech, advantage is that no need to consume electric energy, but takes full advantage of extra steam energy, and more powerful, more stable, can hold
Continuous work.
In some embodiments, the caisson 7 is air reservoir or underground cave hole, but is necessary for closed space,
I.e. when with hot low ebb, compressed air is stored to caisson 7 by equipment, in compressed air demand or peak of power consumption,
Compressed air can be released and directly feed compressed air user or for generating electricity.
In some embodiments, the expanding machine 4 is turbo-expander.
In some embodiments, first water pump and the second water pump are respectively heat-exchanger pump 11 and water supply pump 12, wherein heat
Water pump 11 and water supply pump 12 are mainly used to the mutual conveying of circulatory mediator.
In some embodiments, the circulating cooling make-up water of the residual neat recovering system is changed using 2 steam discharge of steam turbine by first
Hot 8 waste heat of device condensed water after the recovery, can accomplish recycling for resource.
In some embodiments, the connection type is attached by pipeline.
