Description

Underground reservoir gradient water pumping energy storage system for post-mining abandoned mine
Technical Field
The invention relates to a gradient water pumping energy storage system for an underground reservoir of a post-mining abandoned mine, which is a new energy storage technology and a post-mining abandoned mine underground space and mine water recycling technology.
Background
Solar energy and wind energy are green and pollution-free renewable new energy sources. Nowadays, equipment manufacturing level and technical level of wind energy and solar energy systems have advanced greatly, receiving and converting systems of energy sources have advanced greatly, but energy storage is still a key link. At present, lead storage batteries, lithium ion batteries, nickel-hydrogen batteries and the like are used as a part of energy storage devices, the cost of advanced storage batteries is higher, a high-capacity energy storage technology is not mature, and particularly lithium ion batteries cannot meet the energy storage requirement at present. And the conventional lead storage battery has short cycle life, can not deeply discharge, has high maintenance cost of battery pack operation, and is difficult to meet the requirement of large-scale power storage.
The principle of the water pumping and energy storage is that water is pumped from a lower pool reservoir to an upper pool reservoir in the low valley period of a power load, electric energy is converted into gravitational potential energy to be stored, and the water is released from the upper pool to the lower pool to generate power in the peak period of a power grid load. The method has the advantages of large stored electric energy, long storage time, high response speed, low operating cost per watt of stored energy and the like, but because the method has serious dependence on the terrain, the site selection is difficult, and the investment period is long.
According to the prediction of 'Chinese coal resource high-efficiency recovery and energy-saving strategic research' of Chinese engineering institute key consultation project, the number of mines for capacity removal in China reaches 1.5 ten thousand by 2030 years, and if the number is calculated by 60 ten thousand cubic meters of underground space of a single coal mine, the underground space is about 90 billion cubic meters.
In addition, mine water discharge is an essential process in the coal mining process, according to investigation, the yield of mine water is about twice of that of coal, but the effective utilization rate of mine water is lower than 60%. If the mine water is discharged, not only water resource cost, pollution cleaning cost and resource consumption cost of drainage equipment need to be paid, but also the discharge of the untreated mine water has negative influence on the water quality of surface water, underground water, domestic water and agricultural water.
The energy storage system for realizing water pumping and energy storage by utilizing the underground space of the abandoned mine and mine water is provided by combining the problems of reutilization of underground water and new energy storage of the underground space of the abandoned mine.
Disclosure of Invention
The invention aims to provide a more efficient and economic energy storage system, which reduces the initial investment of water pumping and energy storage, solves the dependence of water pumping and energy storage on geographical conditions and realizes the green and sustainable development of new energy storage on the basis of recycling underground space of abandoned mines and mine water.
The implementation process of the invention comprises the following steps: firstly, a plurality of underground reservoirs with different heights are built by utilizing a goaf, and the underground reservoirs are filled with water sources such as mine water, aquifer water and the like. And secondly, establishing a filtering and purifying water system on the ground, wherein the system needs to have the function of a small tap water treatment plant. And thirdly, establishing a ground sewage treatment plant and a reservoir. And fourthly, pumping water of the lower underground reservoir to the upper underground reservoir by utilizing redundant electric energy generated by new energy sources such as wind energy, photovoltaic energy and the like through a water pump, and selecting the upper reservoir with a proper elevation according to the amount of the electric energy to be stored. Fifth, the mine water pumped to the ground is treated by a ground sewage treatment plant, and the mine water can be supplied to a living area when reaching the water use standard; and sixthly, by utilizing the height difference, surface water or water of the upper reservoir can fall to the lower reservoir through a roadway to generate electricity, and the lower reservoir with the proper height can be selected according to the generated energy.
And the fourth and sixth circulation steps can realize energy storage-release circulation.
The invention can set a plurality of underground reservoirs with different heights according to the distribution condition of the goaf of the abandoned mine, and the original stoping and preparation laneways are used for connecting all the underground reservoirs.
Compared with the traditional water pumping energy storage system, the system solves the problem of dependence of the water pumping energy storage system on the terrain, enlarges the application range of the water pumping energy storage system, reduces the initial investment and shortens the investment period. And the system comprehensively utilizes the underground space of the abandoned mine and mine water while solving the problem of new energy storage. The method has the advantages of reducing the initial cost of new energy storage, realizing secondary utilization of underground space of the abandoned mine after mining, achieving 'win-win' and realizing cyclic utilization of underground mine water, and providing transformation reference for the mine which is about to quit the capacity.

Detailed Description
Engineering cases: the system is set up as shown in figure 1 according to the corresponding geological and mine mining conditions
The first step is as follows: the mine water is treated and then injected into an underground reservoir 11 for storage
The second step is that: when the wind energy 1 and the light energy 2 generate redundant electric energy, the ground water pump 3 or the underground water pump 13 is started by the transformer 4 to pump the water of the low-level reservoir to the high-level reservoir; the water pumping quantity and the corresponding height difference of the reservoir can be properly selected according to the amount of the redundant energy.
The third step: when the power generation by the wind energy 1 and the light energy 2 can not meet the power demand, the water in the high reservoir is put into the low reservoir, the gravitational potential energy generated by the water drives the generator to generate power 12 by utilizing the altitude difference, the generated electric quantity is converted by the transformer 10, and the electric quantity can be transmitted to the living area 6 by utilizing the power transmission line 8 for use; the reservoir and the water quantity with the suitable height can be selected according to the required electric quantity.
The fourth step: and the water pumping and energy storage can be realized by repeatedly circulating the two steps and the three steps.
When the ground water amount is excessive, the water can be treated by a sewage treatment plant 7 and can be used by a living area 6 after reaching the standard.
When the underground reservoir is lack of water, atmospheric precipitation or other water sources can be used for supplement.
The storage energy of the system depends on the size of underground and ground reservoirs and the amount of water; the rate of energy storage depends on the capacity of the water pump.
