Definitions

  • the invention relates to a device for generating energy in the form of electricity, heat and cold from a body of water flowing within a channel provided with walls according to the preamble of claim 1, hereinafter referred to as HHPP for short (Hybrid Hydro Power Plant).
  • a large number of devices for generating energy using hydroelectric power stations are known from the prior art, in which the water from a higher lake, which can be a reservoir, is guided into a lower lake via pipes, with several pipes at the end of the pipes Turbines and generators are arranged, which generate electricity from the kinetic energy of the water flowing down.
  • Similar constructions are used within rivers, e.g. as so-called shaft power plants or run-of-river power plants.
  • at least part of the river is directed into a shaft in which a turbine and a generator are located.
  • Tidal power plants are mostly located in the area of coasts with strong tidal effects, current power plants are mostly in the area of coasts with strong thermohaline circulations.
  • Hybrid forms of energy generation are also known, such as PVT -Ko hectares (Photo-Voltaic & Thermal) for the simultaneous generation of electricity and heat.
  • PVT -Ko hectares Photo-Voltaic & Thermal
  • the hybrid in the form of a hybrid combustion engine is the best-known example.
  • Tu is the mean temperature of the heat source (approx. 0 ° C for geothermal collectors, 10 ° C for geothermal probes and groundwater and> 11 ° C for energy sheet pile walls)
  • WP the efficiency of the heat pump. This is 0.35 with air HP, 0.45 with brine HP and 0.5 with water HP and is highest with water HP, among other things because the viscosity of water is 4 times lower than with brine with approx. 15% glycol content.
  • CN107781096 A shows a generator with an electric turbine connected to it, on the axis of which - can be decoupled via a coupling - the compressor of a heat pump, which works as a refrigeration machine, is attached, with heat exchangers arranged in the outflow area of the water to dissipate the heat generated in the condenser are. There is no cooling of the water in the inlet area of the turbine - and the associated increase in the efficiency of the turbine - is not given here.
  • the task is to develop a device for generating energy in the form of electricity, heat and cold including the decentralized distribution of the generated heat and cold from a body of water flowing within a channel provided with walls so that the effectiveness of electricity generation and the efficiency of the heat pump are increased.
  • the invention relates in particular to a device for generating energy from a body of water flowing within a channel provided with walls, which drives a turbine arranged in the channel or immediately thereafter. This in turn drives a generator to generate electricity.
  • a device for generating energy from a body of water flowing within a channel provided with walls which drives a turbine arranged in the channel or immediately thereafter.
  • This drives a generator to generate electricity.
  • at least a part of the walls of the channel in the water inlet area is formed by a sheet pile wall equipped with heat conduction pipes for the extraction or supply of thermal energy from the body of water.
  • the heat conduction pipes are advantageously designed either as cavities between adjacent elements of the sheet pile wall or placed on a surface of the sheet pile wall, e.g. on the surface which is opposite the inner duct wall, i.e. which is exposed to water.
  • the heat pipes are connected to a heat pump in order to process the heat extracted from the water and convert it into thermal energy.
  • the channel has, for example, a circumferential wall and is part of a hydroelectric power plant, in which water flows from a higher reservoir through the channel into a lower reservoir. It can therefore be a hydropower plant in a river, in which the guide channels are designed as thermally activated sheet piling walls.
  • the hydropower plant is a shaft power plant within a river, hereinafter referred to as HHPP.
  • the canal is circumferential and the water flows from a higher to a lower level.
  • the concrete walls to be erected during the construction of the shaft power plant to steer and demarcate the water flow from the natural river bed during floods can also be replaced by thermally activated sheet piling in the water inlet area of the turbine, which thus become an integral part of the entire hydropower plant.
  • the thermal extraction capacity can be significantly increased compared to the sole use in the area of the shaft around the turbine. This significantly increases the thermal output of the HHPP, which is advantageous for using the "cold heat" generated in heating networks.
  • the channel can have only lateral walls, that is to say two parallel walls which are arranged essentially perpendicular to the surface of a coastal section of a sea, that is to say a body of water moved by tides, and are thus part of a tidal power plant.
  • the entire area between parallel walls forms the flow area for the water flowing in or out due to the tides and the turbines are arranged between them with axes of rotation parallel to the walls. They can be located within ducts or stand freely between the walls.
  • the walls are preferably arranged parallel to one another, but they can also be placed slightly funnel-shaped to one another, the turbine then being located at the narrowest point of the funnel in order to achieve the highest possible efficiency.
  • TW temperature changing device
  • Fig. 2 a schematic plan view of an inventive
  • a device for generating energy is shown from a flowing body of water.
  • This can be, for example, a river that flows from a higher reservoir 5 into a lower reservoir 6, preferably at a natural position which has these different reservoir heights.
  • the invention can also be implemented with a damming up of the water.
  • the water flows from the higher reservoir 5 through a channel 1, which is equipped with circumferential walls 2, into a turbine 3, which drives a generator (not shown) to generate electrical power.
  • the water leaving the turbine flows through an outflow funnel 7 into the lower reservoir 6 of the body of water.
  • the surfaces of the two reservoirs 5 and 6 are shown curled and represent the water surfaces.
  • the turbine 3 is mounted within the channel 1 with a vertical turbine axis.
  • the channel 1, which houses the turbine 3 and conducts the flow from the higher reservoir 5 into the lower reservoir 6, has lateral walls 2, which can be configured as concrete walls with steel sheet piling in front of them with heat conduction pipes 4, which in turn consist of several, arranged side by side and over the sheet pile interlocks consist of interlocked sheet piles and form a closed channel 1.
  • the heat pipes 4 and the sheet pile walls formed from them are located in the water inlet area of the turbine.
  • the channel 1 that houses the turbine 3 and the flow from the higher reservoir 5 into the lower reservoir 6 has lateral walls 4, which are designed as sheet piling and consist of several adjacent, shaped metal sheets which overlap each other so that one side closed channel 1 is formed from the walls 4.
  • lateral walls 4 which are designed as sheet piling and consist of several adjacent, shaped metal sheets which overlap each other so that one side closed channel 1 is formed from the walls 4.
  • Figure 1 only two opposite side walls of the channel 1 are shown. In reality, it is a structure that is also closed at the front and back.
  • heat conduction pipes 4 Through the inside of the walls 2 of the channel 1 in the water inlet area there are heat conduction pipes 4 through which a liquid flows and which serve to extract thermal energy from the water flowing from the higher reservoir 5 of the turbine 3.
  • the illustration according to FIG. 1 is only schematic.
  • the inlet area of the channel 1 above the turbine 3, i.e. the length of the walls 4, can be considerably larger than in the illustrated embodiment, so that the incoming water flows past the heat pipes 4 within the channel 1 over a much longer distance, and in this way the water more Energy can be withdrawn.
  • This extraction of energy naturally leads to a cooling of the water flowing past, so that the water reaching the turbine 3 is cooler than the water in the higher reservoir 5a and leaves the arrangement in the area of the discharge funnel 6 at a lower temperature.
  • the dynamic viscosity and the density of the water increase, so that a larger amount of water per unit of time flows through the turbine 3 and thus a higher efficiency of the turbine 3 is ensured.
  • the arrangement according to the invention does not only take place at the same time Electricity is generated from the moving water with the help of the turbine and thermal energy is extracted from the water through the heat pipes 4, but the effectiveness and efficiency of the turbine 3 also increases due to the cooling of the water as a result of the heat extraction through the heat pipes 4.
  • the arrangement according to the invention can be used not only in a shaft power plant located within a river, but in a pumped storage power plant.
  • the water flows through a pipe leading from a reservoir at a higher level to a lake at a lower level, which acts as a channel 1 and also has walls 2.
  • On these walls 2 there are also heat conduction pipes 8, which extract thermal energy from the water on the way from the reservoir to the valley and thereby cool it down.
  • the cooled water then meets an arrangement of turbines and generators in a manner known per se, whereby electrical energy is produced and is then released into a lower lake.
  • the effectiveness and the efficiency of the turbine 3 are increased due to the cooler and thus denser and more viscous water.
  • a reverse process is possible in summer when cold is required for air conditioning instead of heat for heating. This is possible by reversing the process, in that the heat pipes are not fed by a cold medium from the evaporator of a HP, but by a warm medium from the condenser, whereby the body of water warms up slightly. Since the medium is cooled to temperatures close to the water temperature, cooling is usually possible as free cooling without falling below the dew point, i.e. without going through a chiller, which significantly reduces operating costs.
  • the invention can also be used in a tidal or ocean current power plant, as shown schematically in FIG. 2.
  • Power plants of this type are usually set up in coastal regions and use the oscillating movement of the water due to the tidal effect or the continuous flow due to thermohaline ocean currents.
  • a plurality of turbines can also be fitted one behind the other in a duct, as is shown schematically in FIG.
  • Tidal power plants are usually set up in shallow coastal regions and use the oscillating movement of the water due to the effects of the tides.
  • walls 2 are driven into the sea floor, namely several walls 2 parallel to one another. This creates channels 1 between the walls 2, each of which has a wall 2 as an exclusive boundary.
  • the turbines 3, which are shown schematically, are located within these channels 1.
  • the axis of the impeller of the turbine 3 is in the direction of flow (indicated by arrows) of the water during passage through the channels 1 as a result of the tidal currents.
  • the walls 2 are usually oriented towards the land, since the tides move from the land to the sea and back again.
  • the arrangement of the walls 2 can, however, be adapted to local tidal currents.
  • the direction of flow of the water flowing through the channels 1 is of course reversed as a result of the tides, so it does not always run in the direction of the arrow, but also in the opposite direction.
  • the turbines 3 accordingly rotate alternately in one direction and the other.
  • the walls 2 of the channels are designed as sheet piling which are driven into the seabed and have heat conduction pipes 4 which are arranged vertically on the walls 2.
  • the thermal extraction capacity is not limited, since in the subject matter of the present invention the heat exchanger is part of the static construction of the power plant. According to the invention, there is no risk of the power plant rake being damaged by debris in the event of flooding, since the heat conduction pipes are arranged in a protected manner behind the sheet pile wall. In addition, the functionality of the is usually inclined and exposed at low tide Power plant rake in winter is not restricted according to the invention, because the heat pipes are positioned exclusively in the area under water.
  • the walls 2 can also be arranged in the shape of a funnel, so that the turbines 3 are arranged at the narrowest point of the funnel. It is also possible to restrict the flow rate within the channels in the area of the turbines, so that the water flowing through can only flow through the area of the turbines 3 and thus a higher flow rate and thus a higher speed of the turbine is generated.
