Description
Technical field
The present invention relates to field of energy utilization more particularly to a kind of systems of using mid-deep strata rock hot well heat accumulation.
Background technique
With Chinese society expanding economy, heating energy consumption is growing, while green clean reproducible energy heating
As mainstream, the cleaning heat source for being presently available for heating or supplying hot water includes solar energy, geothermal energy, industrial exhaust heat etc..In China
During building energy consumption is constituted, Heating,Ventilating and Air Conditioning energy consumption accounts for about the 60% of total energy consumption, this part energy consumption structure is still with fossil energy
It is main, aggravate the atmospheric pollution level in China.Therefore, for central heating industry, renewable energy especially solar energy, geothermal energy etc.
It is paid high attention to and is widely applied by the Chinese government.However, there is significant seasonal feature in northern China Heating,Ventilating and Air Conditioning supply and demand,
Summer solar energy and waste heat, heat sources are abundant, but tend not to be used effectively, and winter is then on the contrary, solar energy and waste heat money
Source is deficient, it is difficult to meet the needs of people are to thermal energy.The earth storage body huge as one has and realizes that energy is especially warm
The potentiality that can be stored for a long time on a large scale.
Solar energy is green clean reproducible energy.China is vast in territory, and area of the sunshine-duration in year greater than 2000h accounts for about
In the region advantageous using solar energy, but there is interval in the practical utilization of solar energy in the 2/3 of national national territorial area
The low disadvantage of property, season disequilibrium, energy-flux density.
Industrial exhaust heat refers to the limitation due to factors such as technology, theories, in the industrial enterprise's energy-consuming device to have put into operation,
The sensible heat and latent heat that original design is not used appropriately, it includes high-temp waste gas waste heat, cooling medium waste heat, more than waste vapour waste water
Hot, high-temperature product and afterheat of slags, chemical reaction waste heat, combustible exhaust gas waste liquid and waste material waste heat etc..According to investigation, every profession and trade
Waste heat total resources account for about the 17% ~ 67% of its fuel consumption total amount, and the residual heat resources of recoverable are about waste heat total resources
60%, it can be seen that industrial exhaust heat and waste heat have huge economic benefit and social benefit as can effective recycling.
Geothermal energy be derived from the earth melting magma and radioactive substance decay, and in the form of heating power existing for renewable energy
Source, the exploitation of mid-deep strata geothermal energy is at present based on interference-free rock thermal technology.
Solar energy and geothermal energy are all inexhaustible, nexhaustible clean energy resourcies, all have sustainable, pollution-free, money
The features such as source amount is big, distribution is wide, and the recycling of industrial exhaust heat and waste heat is developed after study, way of recycling is various at present,
Method is reliable, and technology is constantly progressive.The utilization of heat source described above is like a raging fire in development of clean energy utilization, all has good
Good social benefit and environmental benefit, but some problems are encountered simultaneously, such as：Using when solar-heating by by daylighting area institute
Limit, heat capacity are insufficient, while cannot be fully utilized instead non-heating season solar energy resources are more sufficient, cause mass energy unrestrained
Take, the idleness of equipment；Mid-deep strata underground heat energy, which cannot be supplemented sufficiently, will appear a degree of decaying, and industrial exhaust heat and waste heat are same
There is unbalanced supply-demand in sample.
Summary of the invention
Using mid-deep strata the rock that technical problem to be solved by the invention is to provide a kind of configurations simply, operation is low in energy consumption
The system of hot well heat accumulation.
To solve the above problems, a kind of system of using mid-deep strata rock hot well heat accumulation of the present invention, feature exist
In：The system includes thermal energy collecting element, thermal energy converter, with being placed in the mid-deep strata ground of the mid-deep strata in rock hot well rock heat exchanger
And control system；The thermal energy collecting element is connected by heat exchange cycle pipeline I with the thermal energy converter；The thermal energy collecting
Element is pumped by heat exchange cycle pipeline II through heat exchange cycle to be connected with the thermal energy converter；The thermal energy converter passes through heat accumulation
Circulation line I is connected through the influent side of with the mid-deep strata the rock heat exchanger of control valve I；The thermal energy converter passes through heat accumulation
Water outlet side of the circulation line II successively through heat accumulation circulating pump, control valve II with the mid-deep strata rock heat exchanger is connected；It is described
Heat exchange cycle pipeline I and the heat accumulation circulation line I are respectively equipped with temperature probe；The temperature probe, the heat exchange cycle pump,
The heat accumulation circulating pump, the control valve I, the control valve II are connected with the control system.
The thermal energy collecting element refers to the recyclable device or other heat sources of solar energy heat collector, industrial exhaust heat and waste heat
Device.
The mid-deep strata rock hot well be directed to 2000 ~ 3000 meters of underground drilling of interference-free rock hot well.
Compared with the prior art, the present invention has the following advantages：
1, since solar energy, industrial exhaust heat and waste heat have the characteristics that significant seasonal and unbalanced supply-demand, heat is negative in winter
In lotus demand high season, solar energy and industrial waste heat resource are less, and anti-in season heat resource of the summer without thermal load demands
And it is more.To improve resource utilization, reducing equipment vacancy rate, improvement mid-deep strata geothermal energy resources, expansion industrial exhaust heat and waste heat
The approach of recycling, using mid-deep strata rock is as thermal store by the present invention, and water is as heat accumulation heating agent, by rich solar energy, work
The resources such as amateurish heat or waste heat in rock, are needed next for the hot season while 2000 meters of mid-deep stratas below are stored in the form of thermal energy
It is taken out again by medium when wanting and is used for building heating, industrial or agricultural application, not only realized and adjust resource supply and demand, season unbalanced work
With, and reduce the Exploitation degree of centering deep geothermal resources, the utilization to solar energy resources is increased, has been expanded industrial remaining
The recycling approach of heat and waste heat；Any environmental risk and discharge will not be brought simultaneously.
2, present invention configuration is simple, operation is low in energy consumption, is novel, the environmentally friendly thermal energy storage of one kind and utilization side
Formula.
