Definitions

  • the present invention relates to geothermal energy and can be used to remove the thermal energy of the Earth from hydrothermal deposits.
  • the direct method is used to extract the Earth’s thermal energy - using dry steam, in which steam naturally breaks out from the well under high pressure
  • the indirect method is using water vapor from low-temperature hydrothermal deposits, a steam-water mixture or brine, pumped out of wells.
  • a characteristic representative of the above method of Earth heat extraction is a device for using geothermal energy to obtain mechanical energy proposed in patent Ru 2330219.
  • the Earth heat removal circuit of the device in question consists of a hermetically sealed lowering pipe located in the well. Inside the lowering pipe, a lifting pipe is coaxially located, the outer side of which has a heat-insulating layer.
  • the riser pipe is connected to the inlet of the heat exchanger.
  • the heat exchanger output through the valve is connected to the inlet of the circulation pump.
  • the output of the heat exchanger circulation pump is connected to the inlet of the downpipe.
  • the coolant circulates in the device. Pure water is used as a heat carrier.
  • the disadvantage of this device is that in it the circulation of the coolant is carried out by the comprehensive movement of the mass of the coolant. This does not allow the coolant to be in the heating zone for sufficient time to remove the heat of the Earth.
  • the use of clean water as a coolant in this device also does not allow it to be heated above the boiling point of water, and the absence of thermal insulation in the upper part of the lowering pipe located in the low-temperature layers of the Earth leads to loss of thermal energy, which leads to a decrease in the efficiency of the device. Forced circulation of the coolant by pumping it into the downcomer due to the occurrence of significant volumetric backpressure of the coolant leads to energy losses for the drive of the circulation pump.
  • the basis of the invention is the task of creating a fundamentally new type of geothermal device - mine geothermal device.
  • a heat carrier pool is created in the device, and high-boiling organic liquids (glycerin, alkyl diphenyls, polyphenyls, eutectic hydrocarbons, etc.) are used as the heat carrier.

  • Figure 2 shows a General view of the shaft shaft of a geothermal device.
  • Fig. 3 shows a general view of the shutter.
  • Figure 1 shows an example of the use of a mine geothermal device in the generation of electrical energy from a geo-TPP with a binary cycle.
  • a mine shaft 3 of a geothermal device with a diameter of at least 1.6 meters is installed in a mine of a hydrothermal field (Fig. 1).
  • the casing consists of a steel pipe 2 and the top cover 9. Its surface in contact with the soil to the level of the heating zone - the upper edge of the pool has a heat-insulated layer 3. This layer prevents the loss of thermal energy of the coolant accumulated by the pool due to the contact of the shaft shaft housing 3 with low-temperature layers soil (figure 2).
  • a welding belt 1 is fastened in the form of a ring (Fig. 2).
  • the top cover 4 protects the housing from foreign objects from entering it from the outside. It has an opening 5 for the removal of steam and gas forming during operation from the housing, openings for the supply pipe 8, return pipe 12 and cable for lowering and raising the shutter 7 (figure 2).
  • a shutter 2 is installed inside the shaft 3 (Fig. 1), attached with a cable to a device for lowering and raising the shutter, which is connected to the hook 7 (Fig. 3).
  • the shutter consists of a base 2 and a cover 3. On the base there is a drainage hole 6, sealing gaskets 1 and 4, and guide racks 9 are also attached to it. On the cover 3 there is a sealing gasket 5 and drainage holes 8 (Fig. 3).
  • the shutter has I and II positions (Fig.Z). I position corresponds to lowering and, if necessary, raising the shutter.
  • the shutter 2 using a cable 6 lowers to the bottom of the shaft shaft 3 (figure 1).
  • liquids and gas located in the shaft 3 (Fig. 1) pass through its drainage hole 6 on the base 2 and the drainage holes 8 on the cover 3. Thus, they do not impede the shutter downward movement.
  • the tightness of the bottom of the shaft does not allow further penetration into the pool of the coolant 5 steam, steam-water mixture, brine or gas from the surrounding space into the cavity of the shaft 3 and their mixing with the coolant, and also prevents leakage of the coolant from the pool 5 (Fig. 1).
  • the shutter 2 After installing the shutter 2 in the shaft shaft housing 3 (Fig. 1), its internal cavity is freed from the liquids present in it. Then, a high-boiling liquid organic coolant is poured into it to the upper edge of the pool. The amount of coolant depends on the volume of the pool, pipes and equipment spaces filled during operation of the entire power plant.
  • the location level of the upper edge of the coolant pool 5 is determined by the depth of the geothermal fluid 4 providing heating of the coolant to the required operating temperature, and the depth and diameter of the coolant pool 5 depend on the temperature and thermal conductivity of the surrounding environment of the pool and the required thermal energy productivity (Fig. 1).
  • Heating of the coolant pool 5 occurs from its direct contact with the steel body of the shaft shaft 3 heated by geothermal fluid 4.
  • the heated coolant through the supply pipe 8, the end of which is located at a depth of 10 m of the coolant pool 5, is pumped out of the pool by the pump 13 into the heat exchanger 14.

  • the end of the return pipe 12 is 1 m above the coolant pool 5 (Fig. 1).
  • a geothermal installation with a binary cycle consisting of a heat exchanger 14, a turbine 16, a generator 15, a condenser 17, a pump 18 and a network of pipelines operates in a closed circuit (Fig. 1).
  • the proposed design of the mine geothermal device allows you to remove the thermal energy of the Earth removing steam, steam-water mixture or brine to the surface of the earth. This allows you to maintain a constant volume and structure of steam, steam-water mixture or brine, which are heat carriers of the thermal energy of the bowels of hydrothermal deposits. In turn, they ensure the supply of constant thermal energy to the mine geothermal device and the unlimited operation of hydrothermal deposits.
  • the innovations of the proposed mine geothermal device make it possible to achieve stability and controllability of the produced heat from hydrothermal deposits and their unlimited operation without harming the environment by harmful emissions, as well as simplifying the design of Geothermal Power Plants and other power plants operating on thermal energy of hydrothermal deposits, reducing the cost of electrical energy for their maintenance and will contribute to a significant expansion of the scope of geothermal power industry.

Abstract

L'invention concerne un dispositif minier géothermique qui peut être utilisé pour prélever l'énergie thermique de la Terre depuis des gisements hydrothermaux. Ce dispositif minier géothermique comprend un corps qui est fait d'un tube d'acier avec une surface à isolation thermique partielle, un fond fermé de manière étanche et un sommet, et qui est disposé dans un puits de mine. Afin d'augmenter l'intensité de prélèvement de l'énergie thermique de la Terre, on utilise un caloporteur organique liquide à point d'ébullition élevé qui circule dans un système clos "cuve de caloporteur - échangeur de chaleur - cuve de caloporteur". Le dispositif minier géothermique permet de prélever l'énergie thermique de la Terre depuis des gisements hydrothermaux sans extraire de vapeur, de mélange d'eau et de vapeur ni de saumure vers la surface du sol, de conserver leur volume et leur structure aux coeurs des gisements hydrothermaux, d'obtenir une stabilité et une capacité de commande de l'énergie thermique extraite, d'exploiter immédiatement les gisements hydrothermaux indépendamment du débit de vapeur, de mélange d'eau et de vapeur et de saumure dans ces derniers, de simplifier la structure des installations énergétiques fonctionnant grâce à l'énergie thermique des gisements hydrothermaux, d'éliminer totatlement les rejets nocifs dans l'environnement, d'élargir les zone d'exploitation des dispositifs géothermiques, comme les vallées de geysers, les volcans de boue, etc.
