Description

To adjust the high-pressure gas device and adjusting method that gas storage temperature improves gas storage efficiency
Technical field
The present invention relates to gas compression and technical field of energy storage, and gas storage efficiency is improved more particularly to adjust gas storage temperature High-pressure gas device and adjusting method.
Background technology
Gases at high pressure are widely used in industrial production and daily life, especially in large scale industry production application, it is necessary to Frequently inflation/deflation is carried out to the high pressure gas storage tank of Large Copacity.Meanwhile a kind of emerging energy storage technology, i.e. compressed-air energy storage Technology, have begun in global popularization and application.The technology uses air as energy-accumulating medium, and air boil down to thermal energy storage process is empty Gas is expanded to exoergic process；Compressed-air energy-storage system is generally day circulating working mode, therefore in compressed-air energy-storage system In need to caisson carry out frequently inflation/deflation circulate.
In compressed-air energy-storage system, because turbo-expander has certain requirement to admission pressure, air storage chamber is from most When high gas storage pressure is deflated to turbo-expander minimum admission pressure, deflation course terminates, thus gas replenishment process is also by the pressure Power starts.Remember that air storage chamber highest and minimum gas storage pressure are respectively phAnd pl, and define air storage chamber gas storage efficiency and pressed for air storage chamber Power phTo pressure plIn the range of the ratio between discharge quantity and gas-storing capacity, i.e. η=mout/min。
In gas replenishment process, because intake air temperature is higher, compression fuel factor caused by air storage chamber, inflation in gas replenishment process in addition At the end of temperature T in air storage chamberhIt will be above temperature (environment temperature) T when inflation starts0, according to The Ideal-Gas Equation p*Mmol=ρ * R*T, the aeration quantity m of air storage chamberinFor：
min=(ρh-ρ0) * V=(ph/Th-p0/T0)*V
During gas storage, gas storage indoor gas is exchanged heat by wall and environment, because gas storage process is longer, in air storage chamber most Finishing temperature is reduced to environment temperature T0, while gas storage room pressure is reduced to p0', but gas-storing capacity is constant, namely gas storage density is not Become.
In deflation course, because gas storage intraventricular pressure insists on continuous reduction, swell refrigeration effect, air storage chamber at the end of deflation are produced Interior temperature TlIt will be less than the temperature T to deflate when starting0, according to The Ideal-Gas Equation p*Mmol=ρ * R*T, air storage chamber fill Tolerance moutFor：
mout=(ρ0-ρl) * V=(p0/T0-pl/Tl)*V
After deflation terminates, air storage chamber to inflate again again after low-pressure state standing for long periods, gas storage Indoor Air during this Body is exchanged heat by wall and environment, and final temperature is increased to environment temperature T in air storage chamber0, while gas storage room pressure is increased to p0, inflation/deflation circulation completion.
Then the gas storage efficiency of air storage chamber is：
η=mout/min=[T0/Th*(ph/p0)-1]/[1-T0/Tl*(pl/p0)]
For a certain compressed-air energy-storage system, T0*ph/p0And T0*pl/p0For constant, C is designated as respectively1And C2, then gas storage Room gas storage efficiency is：
η=(C1/Th-1)/(1-C2/Tl)
Obviously, gas storage efficiency eta is with maximum temperature ThReduce and increase, and with minimum temperature TlRaise and increase.
In summary, actual aeration quantity is caused to reduce in gas replenishment process because the temperature rises, and due to gas in deflation course Temperature drop is low and causes actual discharge quantity further to reduce, and the temperature change during inflation/deflation reduces the inflation/deflation of caisson Internal circulating load, so as to influence the energy storage efficiency of compressed-air energy-storage system and economic benefit.If can be in caisson inflation/deflation During the temperature in air cavity is maintained in stability range, the unit volume internal circulating load of caisson will be significantly improved, and then Improve energy storage efficiency and economic benefit.
