Abstract
The utility model discloses a mine terrestrial heat energy utilizing device, comprising a heat pump machine groups 1, circulating pipelines 2, 3, a circulating water pump 4, a high and low pressure heat exchanger 5, a water pump 6, a water supplying pipe 7, a water draining pipe 8, and a water cabin at the bottom of the mine. The utility model is characterized in that the high and low pressure heat exchanger 5 is arranged under the mine; the circulating water pump 4 and a heat pump machine group 6 are arranged on the ground. The heat pump machine group distills the heat in the circulating water which distills the heat in the cabin at the bottom of the mine through the high and low pressure heat exchanger; the water under the mine is drained in the laneway which has a certain distance from the water cabin through a pipeline; after absorbing the terrestrial heat energy of the air under the laneway rock mine, the water returns to the water cabin at the bottom of the mine along the terrestrial grades. The final heat source of the heat pump machine group is the terrestrial heat energy under the mine. The heat pump machine group utilizes the terrestrial heat energy for the building heating of mine, scouring bath and frostbite preventing of mine canister.
Description
Technical field
The utility model relates to geothermal energy utilization technology, technical field of heat pumps.
Background technology
In the mine production process, for ordinary production and the safety that guarantees mine, need constantly draining earthward, discharge the mine water on ground, annual temperature substantially constant cool in summer and warm in winter is the desirable water source of water resource heat pump.Through the heat that water resource heat pump extracts, can be used for the building and heating of coal mining enterprise, bathing, and pit shaft is antifreeze, can freeze summer.But China is lack of water big country, and is especially less in a lot of mine drainage underground amounts of central and west regions, is difficult to guarantee the needed water yield of normal operation of source pump, thereby limited the popularization of water source heat pump technology in mine enterprise greatly.On the other hand, a large amount of geothermal energy of containing of mine underground mining can't effectively be utilized.
Summary of the invention
The purpose of this utility model is: propose a kind of mine geothermal energy utilization device, for the geothermal energy of the cleaning of extracting the down-hole, offer coal mining enterprise's productive life with heat, substitute present coal-burning boiler heating system.
The utility model also is: a kind of device that can efficiently utilize mine underground heat is provided, utilize this device in the little mine of displacement, to extract geothermal energy efficiently, and the heating, bathing, the pit shaft that are used for coal mining enterprise after heat (or cold) promoted by heat pump are antifreeze, and summer refrigeration cool-down.The technical scheme that its technical problem that solves the utility model adopts is summarized as follows:
The utility model purpose is achieved in that mine geothermal energy utilization device, comprises source pump 1, circulation line 2,3, water circulating pump 4, high-low pressure heat exchanger 5, suction pump 6, feed pipe 7, drainpipe 8, wellhole 9.Utilize water pump to extract mine mine water and the recirculated water heat exchange in the high-low pressure heat exchanger in the wellhole, heat is passed replace to recirculated water.Be extracted the mine water behind the heat, be transported to tunnel discharging apart from the sump certain distance by pipeline, mine water and tunnel, rock and air generation heat exchange, fully absorb its energy after, by the tunnel terrain slope, return wellhole naturally and recycle.The recirculated water that obtains heat enters surface-based source pump by circulation line, and source pump is extracted heat in the recirculated water, supplies with the building and heating of coal mining enterprise, bathing, and pit shaft is antifreeze etc.Circulation line and high-low pressure heat exchanger form U type pipe principle, and water circulating pump only need overcome resistance of ducting loss and get final product.
Concrete working method of the present utility model is: source pump is extracted the heat in the recirculated water, recirculated water extracts the heat of water in the wellhole by the high-low pressure heat exchanger, mine water discharges in the tunnel of distance sump certain distance by pipeline, after absorbing the geothermal energy in tunnel, rock and the underground air, return wellhole along the tunnel gradient.The final thermal source of source pump is a down-hole underground heat.Source pump is used for the mining area building and heating with the geothermal energy of extracting, and bathing and pit shaft are antifreeze.
Description of drawings
Fig. 1 the utility model operation principle and system schematic
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.As shown in Figure 1, the utility model exemplifying embodiment, by source pump 1, circulation line 2,3, water circulating pump 4, high-low pressure heat exchanger 5, suction pump 6, feed pipe 7, drainpipe 8, wellhole 9 is formed.When the utility model normally moves, underworkings, rock and air with mine water generation heat exchange, the geothermal energy biography that self contains is replaced to mine water, mine water flow back into wellhole 9 by terrain slope, the mine water that suction pump extracts in the wellhole 9 enters high-low pressure heat exchanger 5, the back is by drainpipe 8, in the discharging of the tunnel of distance sump certain distance, after recirculated water absorbs the heat of mine water by high-low pressure heat exchanger 5, by circulation line 3 and water circulating pump 4, enter source pump, enter high-low pressure heat exchanger 5 by circulation pipe 2 again behind the heat in the source pump extraction recirculated water.
Characteristics of the present utility model are, by source pump, final extract Rock in Well, tunnel and air In geothermal energy. Water circulating pump only needs very littlely to overcome drag losses and can fully extract energy in the mine water, Utilize the capacity of shaft sump as the recycling balancing tank of mine water. With less energy consumption, obtain Enough geothermal energies.
In sum, the utility model takes full advantage of characteristics and the U-shaped pipe principle of mine, with higher efficient Extracted the geothermal energy of down-hole, energy-conserving and environment-protective. The utility model is promoted at the less mine of displacement, must To bring huge economic benefit and environmental benefit to enterprise.
