Description
Technical field
The utility model belongs to combustion gas bunkerage more particularly to a kind of device of Large Underground combustion gas gas storage.
Background technology
With the development of society, natural gas is rapidly developed and is widely applied as clean energy resource, high efficient energy sources, in
The relevant power generation of the people's livelihood, industrial chemicals, new-energy automobile, especially occupy domestic gas, serious dependence are all produced to natural gas.
Since China reforms and opens up to the outside world, sustained economic growth, people's lives constantly improve, and pursue good living environment and sustainable development mesh
Mark has become the important component of Strategy of Well-off Society, and dirty in face of China overwhelming majority cities and towns coal smoke type
Contaminate makeing the formal commitment for the emission reduction CO2 greenhouse gases that serious atmospheric environment and the Chinese government are made to the whole world, Devoting Major Efforts To Developing profit
With the efficient clear energy sources such as natural gas, accelerate adjustment, Optimization of Energy Structure, improve the ecological environment and realize sustainable development conscientiously
One of target, the significant problem just solved as most an urgent demand after China's New Century.It is provided in face of above-mentioned China's natural gas
Source is possesed and active demand of the economic development to natural gas, though country taken transfering natural gas from the west to the east, the disembarkation of extra large gas, northern gas southing and into
A series of Strategic Measures such as mouth LNG, to accelerate China's natural gas industrial development and promote China's Energy restructuring, this is to solving
Domestic energy supply and demand contradiction, environmental pressure and raising efficiency of economic operations and economic and social benefits have played very important work
With.Natural gas not only can alleviate imbalance between supply and demand, and for improving as a kind of clean and effective energy with Optimization of Energy Structure
City taste, improvement environment, raising people's living standard and realization sustainable development will all be played the role of highly important.Naturally
Gas has been the necessity of life of urban resident, and the supply of natural gas is directly related to the power generation, heating and catering trade in city.Ensure
Natural gas supply is also our fundamental state policy, due to being continuously increased for urban population, especially warming, is become with gas height
Peak, the situation that supply falls short of demand happen occasionally.To curb environmental pollution, the coal carried out on a large scale in Beijing-tianjin-hebei Region in recent years changes
Gas makes civil natural gas consumption figure rapid growth.Since this year enters winter, country of Central Asia meets with cold snap, works as to ensure
Ground occupies domestic gas, monthly subtracts for 1,200,000,000 sides, decrement nearly 1/3rd, huge on the natural gas supply influence of China, causes complete
The gas of state's range large area is waste, the coming years, changes the quickening of gas process along with coal, and the situation of Natural Gas Demand anxiety will be into
One step is aggravated.At present, China's major part city gas is mainly by transfering natural gas from the west to the east, extra large gas disembarkation, northern gas southing and country's oil gas
For the gas in field by pipeline, imported L NG sides need steamer, train, the transport of automobile tank body.Due to most of city
All without large-scale gas storage equipment, when outside, gas supply is reduced or supply air line breaks down, and is occurred during also transport LNG
When problem, in addition round the clock with the other factors such as gas lack of uniformity, it can all directly contribute that urban district gas supply is fluctuated, and gas supply subtracts
Less or the phenomenon that cut-off, the serious production and life for affecting the people.Therefore, short time cut-off, season how to be solved
Property it is insufficient, ensure the problem of city successively supplies, just for pendulum in face of us, it is best choosing undoubtedly to store gas
It selects, gas production factory gas storage is in the season of natural gas abundance, natural gas is pushed back underground gas storage layer, until using the busy season again
It is mined.City is no this storage conditions certainly, current air accumulator, big also with regard to tens cubes, by one
Cities are waited, if Zhengzhou City calculates, natural gas day gas consumption in Zhengzhou City's is more than 600 ten thousand steres, is asked with current air accumulator solution
Topic, as an utterly inadequate amount is impossible.
