Description

Energy generation with self-sufficient hydropower plants

1 Introduction

The teaching of the present application relates to the further development of the previous technology for energy generation with self-sufficient hydropower systems (PCT / DE2016 / 000057; published as WO 2017/054791 A1) to include new systems, which are subsequently referred to as Type 2.2, Type 3.2, Type 4.2 and Type 5.2.

As with the previous technology, the difference in the performance of the systems according to the invention is that type 2.2 was designed for small systems, type 3.2 for small cities and small industries, type 4.2 for medium-sized cities with up to 750,000 inhabitants or for large-scale industry. The new type 5.2, which has no counterpart in the previous technology, is particularly suitable for medium-sized residential buildings and industrial buildings with different construction heights.

2 Introduction

As a result of the advantageous and coherent combination of individual groups, there is a high and free energy gain, which, based on wind power, is ultimately only generated via the gravity of the air envelope, through the atmospheric air pressure of approx. 1.0 bar.

The main advantage is that the air pressure is not dependent on constantly changing conditions, as is the case with the production of wind and solar energy but that the air envelope with its weight is permanently and almost constantly available to the system 24 hours a day, day and night.

The way the system works is very simple, the technology has matured over decades and can be used anywhere. Due to the physical and practical clarity, nothing can stand in the way of recognition.

The system essentially consists of three main groups: a water pumping system with highly efficient pump units, a water lifting system with the free use of air pressure and the supply of the water flow to a self-explanatory bulb turbine system, which generates the water power via a generator-transformer block

Generation of energy for own electricity and for energy gain for feeding into the power grid.

In detail, the self-sufficient hydropower plant of the present invention contains at least one of the following components: (i) lower basin (1) for water,

(ii) upper basin (2) for water,

(iii) Siphon line (3) between lower basin (1) and upper basin (2), with the siphon line (3) having an inflow siphon line section (4), an inflow nozzle (5) belonging to this, an outflow siphon section (6) , an outflow nozzle (7) belonging to this, and a connecting section (8) between the inflow and outflow siphon line section,

(iv) vacuum pump (9) in the connecting section (8),

(v) Turbine (10), the inflow of the turbine being connected to the outflow nozzle (7), the outflow of the turbine into the lower basin (1) and the turbine being connected to a generator (11) and a gearbox (23) is

(vi) propeller pump (12) or centrifugal pump (36) for returning water from lower basin (1) to upper basin (2), and

(Vii) in the lower basin (1) and arranged downstream of the turbine (10) gate valve (13) with downstream suction pipe (25). The flea difference between the upper basin (2) and the lower basin (1) as well as the type of pump must be selected in such a way that the optimum operating point and the resulting optimized pumping capacity is achieved for the return of the water to the upper basin (2), in order to keep the relevant internal electricity requirement as low as possible to keep.

3. Description

The operation of the systems to be patented hereby is as a circuit open to the ambient air or to the air pressure (24) using the weight of the air envelope with approx. 10 N (Newton) per cm ² (approx. 1 bar) as the driving force on one side and understand the gravity of water on the other hand. It should be noted that an open circuit differs from a closed circuit in that a closed, hermetically encapsulated circuit does not allow any energy to be generated according to the law of conservation of energy - without the use of air pressure (24). In relation to the systems of type 2.2 to 5.2, the open circuit under air pressure conditions only depends on creating a large difference in height between the upper basin (2) and the lower basin (1) and the height (26) of the siphon line (3) to maximize above the water level (31) of the upper basin (2), so that the greatest possible height difference (26) and thus a large height of fall (20) to the turbine (10) is created. The advantage over other ecological methods of energy generation, such as river power plants, which are naturally limited in the height of fall, lies in the variable possibility of setting the height of fall (20) and the pool sizes (1) / (2) by selecting a type adapt to the local conditions. The greater the height of fall (20) and the greater the inside diameter of the pipe, the more water can flow through the system in the same period of time and the more energy can be generated. The height of fall (20) is in the range from 5.00 m to 30.00 m, preferably from 9.00 m to 18.00 m, particularly preferably from 10.00 to 16.00 m, depending on the type of system. In the preferred embodiments Type 2.2, Type 3.2, Type 4.2 and Type 5.2 have a fall height of 12.50 m, 12.90 m, 15.30 m and 10.00 m, respectively Air pressure (24) an external force effective. The 1st law of thermodynamics is not violated; the system is therefore not a perpetual motion machine, which has been proven by numerous experiments.

4. Evacuation / venting of the siphon line (3)

The prerequisite for the siphon system (3) to operate smoothly and synchronously with all pumps is that the electric gate valve (13) on the sloping drainage siphon line section (6) in front of the turbine outlet (10) in the lower basin ( 1) is locked via the computer management. Furthermore, the siphon line (3) must be completely vented. An additional work step is required to vent a siphon line with a height of more than 8.50 m (26) because the practical suction height of vacuum pumps (9) would be significantly exceeded. Two variants 4a and 4b are available for venting the siphon line (3):

4a) The venting of all air within the pipe system takes place under the condition that the conically outwardly shaped nozzle (5) of the inflow siphon section (4) in the upper basin (2) is constantly under water and that air entry is excluded. This means that the management activates the pump management for pumping water after the gate valve (13) is closed, so that a constant water level (31) can be generated and permanently regulated in the upper basin (2) for ventilation via a sensor (32). During the venting process, the water in the inflow siphon section (4) will run from a rise height (21) over the upper connecting section (8) between the inflow and outflow siphon line into the outflow siphon section (6) and fill it up. Said rise height (21) is, for example, 5.96 m for system type 4.2 (resulting from height (26) of 8.50 m minus 2.54 m for the inner pipe diameter of the upper connecting section (8)). The closed slide (13) prevents drainage into the lower basin (1). The water level is due to the air in the pipe system can rise unhindered during the evacuation in the drain siphon section (6), so that the entire siphon line (3) can be completely vented due to the overflowing water and the vacuum venting itself. In variant 4a, the water to be filled comes from the upper basin (2).

4b) In the second variant, with the shut-off valve (13) also closed, an external centrifugal pump (14) is used to transfer the water from the lower basin (29) into the siphon line (6) to the lower edge of the transition piece (8) and to the sensor ( 15) to limit the water volume range (22) promotes. Thus, when the vacuum pump (9) is still switched off, the water cannot flow via the transition piece (8) into the upper basin (2). The advantage of this variant is the shortened evacuation time; the disadvantage in the acquisition and maintenance costs of the pump (14). The ventilation is completed by subsequent sensor or management-controlled shutdown of the centrifugal pump (14) and activation of the vacuum pump (9).

The final process applies to both variants: As soon as the total filling height (drop height) of 15.30 m (20) using the example of type 4.2 from the lower siphon line section with 6.80 m (27) to the upper section with 8.50 m (26) to to the inner upper edge of the connection (8) is reached, the float (16) or a water level sensor (16) sends a signal to the management to switch off the vacuum pump (9), so that the process of precise lifting of the Shut-off valve (13) for the parallel and synchronous increase in output of the propeller pumps (12) or the centrifugal pumps (36) sets in motion. Thanks to the synchronous control, the water flow for energy generation increases proportionally and steadily - up to the maximum water flow.

In summary, the gate valve (13) controls or regulates the start of the venting of the siphon line (3) by means of vacuum pump (s) (9), the synchronous operation of the siphon line (3) and pumps (9) and (12), or (9) and (36), the operation of the system in the event of a pump failure, the water flow and the shutdown of the system. Finally, a comment on the equally widespread opinion that the energy required to remove the air bubbles that collect from time to time in the upper section of the line is high during ongoing operation and that an energy consumption of a maximum of 15 kWh per day cannot be achieved for this. For example, on a historic construction site (Berlin 1927), it can be proven that only a few kilowatt hours were required for the "ongoing ventilation" of the system - for 50 million cubic meters of water (communications from the Polytechnische Gesellschaft 1927, page 251). It is undisputed that the low energy requirement of 1927 around 92 years later can be further and significantly reduced.

5. Basic information on siphon line systems

Lifting systems are very efficient, but their development potential has been underestimated to this day, and the relevant resources therefore remain largely unused. With the possibilities of the vacuum technology at that time for the ventilation of the large pipes and for the holding vacuum, the water could be raised by up to 7.50 m and with today's technology by up to 8.50 m and then into one deeper areas can be transported without any significant expenditure of energy.

The energy expenditure for the vacuum pump (9) is then, as now, only required for pumping out the air and for the automatic operating state during the operation of the system. The power consumption of these dimensions and with modern vacuum pumps during operation and depending on the stationary or mobile version, is now a low 10 to 15 kWh in 24 hours. It should be noted again that a permanent suction effect of the vacuum pumps (9) is only required for the complete venting of the siphon line (3) until the water flows independently. Furthermore, all that is required is an automatic venting system-related system Amounts of air from the ambient air that are lighter than water and generally collect at the highest point in a pipe system.

6. Power requirement and power determination of the system.

The siphon water flow of the system is determined using the following formula:

Q = 1.25 x 10 ⁴

Q = siphon flow in m ³ / h, d = inside pipe diameter in m, e = H-Geo in m, and d = sum of the drag coefficients of pipe sections, bends, etc.

The above formula was used to determine the siphon current Q for types 2.2 to 5.2 for the planned characteristic values H-Geo and the inner pipe diameter. Of course, it is also possible to calculate the corresponding internal pipe diameter for a planned amount of water.

The height (26) of the inflow siphon line (4) above the water level (31) of the upper basin (2) can be at least 8.50 m with pure vacuum ventilation and depending on the terrain height (35) in the mountains and towards sea level by a further increase be adapted to the prevailing air pressure (24). Furthermore, it is sensible and energetically advantageous that the siphon line area (34) below the water level (31) is extended to close to the pool floor (30) and thus against the siphon flow direction - as long as the flow and the pump arrangement (12 ) & (36). The length (34) of the siphon line area below the water level (31) is typically 1-99% of the water depth prevailing there, preferably 50-98%, particularly preferably 75-95%. As the water depth increases, the depth pressure (28) increases in parallel and adds to the atmospheric air pressure (24) of approx. 1 bar by a further approx. 0.1 bar per meter of water depth. As a result, for example, with a siphon line depth (34) of 6.00 m below the water level (31), a depth pressure (28) at the connection (5) of approx. 1.6 bar that is available permanently and free of charge as pressure energy. Furthermore, with type 5.2, for example, the delivery pressure of the water pump (12) must be taken into account. This is approx. 2.1 bar at the pump outlet. This means that at the level of the water entry point in the inflow siphon line section (4) there is a flow pressure of the pump of approx. 1.75 bar. As a result, the total pressure from the gravity pressure of 1.60 bar plus flow pressure of 1.75 bar adds up to = 3.35 bar, which corresponds to a water column of 34.16 meters even before the actual lifting process begins. The siphon line effect then, supported by the base pressure of 3.35 bar, causes a considerable negative pressure in the riser, so that the flow pressure is multiplied.

In the following it is shown how the acting forces behave in an ideally arranged system through the air pressure (24) alone and how the water flow is driven quantitatively and highly effectively. The reason for this is based on the Berlin example from 1927, according to which the following total energy results from Bernoulli's equation:

Equation from: Mitteilungen der Polytechnische Gesellschaft 1927, pages 251 + 252; see also https://de.wikipedia.org/wiki/Bernoulli-Gleichung

kinetische Energie — , wobei:

p: Betriebsdruck (in Pa) y: Dichte von Wasser (997 kg/m³) v: Geschwindigkeit des Wasserstroms (in m/s) g: Erdbeschleunigung (9,81 m/s²). (i) Eine Erhöhung der Heberleitung wirkt sich bei gleichbleibender Wasserspiegeldifferenz nur auf die Komponente der kinetischen Energie aus, da sich die Fallhöhe des Wassers erhöht. Die größere Heberleitungshöhe hat auf die Wasserentnahme keine Auswirkung, weil der atmosphärische Luftdruck das Wasser ohne Energieaufwand in die Heberleitung drückt. The total amount of energy C contains the following forms of energy: the potential energy of the water level difference h, the pressure energy and the

kinetic energy -, where:

p: operating pressure (in Pa) y: density of water (997 kg / m ³ ) v: speed of the water flow (in m / s) g: acceleration due to gravity (9.81 m / s ² ). (i) If the water level difference remains the same, an increase in the siphon line only affects the kinetic energy component, as the height of fall of the water increases. The greater height of the siphon line has no effect on the water withdrawal because the atmospheric air pressure pushes the water into the siphon line without using any energy.

(ii) If, on the other hand, the water level is raised with the upper basin, all 3 components of the equation increase; a) the potential energy of the water level difference h, b) the pressure energy "p" at the entry point of the deeper siphon line and c) the kinetic energy that affects the speed "v ² " of the water flow due to the higher pressure energy "p".

Whether further parameters are responsible for a multiplication of the base pressure has not yet been conclusively clarified in detail. It is certain that the strong negative pressure and the flow speed within the siphon line develop impressive dynamics because the pressure parameters and the forms of energy complement each other perfectly.

Numerous experiments were carried out on the basis of the procedure described, so that in particular the yield from energy generation could be determined to be significantly higher than expected. The evidence was obtained beyond doubt using calibrated measuring devices using the example of type 5.2 and can be reproduced at any time.

7. Pump units

The pump units of the leading manufacturers are similar and self-explanatory, so that when calculating the water cycle, based on the parameters of the systems, only the choice for the most powerful propeller pump (12) for the type 2.2 to 4.2 is to be met with the lowest power consumption. For type 5.2, at least one centrifugal pump (36) is required instead of propeller pump (s) because this type of system was designed for medium-sized residential buildings and industrial buildings with different heights.

8. Bulb turbine (10) with suction pipe (25), connected gear (23) and generator (11)

The function of the bulb turbine (10) is largely self-explanatory. It should be noted that this type of turbine can also be placed horizontally, so to speak on the floor of the system, the water inflow to the turbine (10) (or also to pump (s) (12) or pump (s) (36)) depending on the pool size the system thus takes place from below or from the side. This means that there are no unnecessary height losses that would result in a deeper excavation. A gear (23) can be connected upstream of the generator (11), depending on the type of system or the planned amount of water, to increase the power output, or to adjust the speed of the turbine (10) for direct feed into the power grid. The additional installation of a suction pipe (25) after the turbine should in turn accelerate the transport of the water flow through the turbine. The suction effect of the siphon line (3) in the lower basin (1), which is already present, is thereby additionally reinforced.

9. Notes on construction work

When planning the above hydropower plants, the performance of the vacuum pumps (9) is directly related to the geographical location and thus to the terrain height (35). This means that at sea level the prevailing air pressure is around 1 bar, which is reduced to around 850 mbar with increasing terrain altitude (35) in the area of 1,200 m. During the aforementioned experiments, a state-of-the-art vacuum pump with up to 98 percent fine vacuum was successfully used, so that a suction height of 8.50 m (26) is also possible in higher Regions do not pose a problem and a suction height greater than 8.50 m (26) could be achieved in deeper regions in relation to sea level.

The water levels of the systems of type 2.2 to type 5.2 are monitored depending on the degree of evaporation with 2-stage water level sensors (32) - minimum / maximum - at the 2 specified water levels (31) & (18) and automatically via the following feed-in variants At the feed point (33): groundwater pumping, storage tank, water pipe, or water treatment system kept constant.

Systems of type 2.2 to 5.2 are designed for eternity according to the principle of the white tank, so that, due to the constant operating and drinking water conditions, essentially only the bearings and other rotating components should be regularly serviced and wear parts should be replaced every 20 years as a precaution.

The lower basins (1) and upper basins (2) of the systems of type 2.2 to type 4.2 can be realized in a variety of designs and can, for example, be round, angular, ring-shaped or polygonal, preferably square, hexagonal or octagonal. There can be more than one siphon line (3) and / or more than one pump (12) or (36) per basin. Preferably 1 to 10, particularly preferably 1 to 3, siphon lines and / or preferably 1 to 100, particularly preferably 1 to 54, very particularly preferably 1, 16 or 54 pumps (12) or (36) are present per system.

In a preferred embodiment (type 2.2) the system contains the following components: (i) suitably shaped lower basins (1) and upper basins (2), (ii) a siphon line (3) with vacuum pump (9), turbine (10), gate valve (13), suction pipe (25), gear (23) and generator (11), (iii) a pump (12).

In a further preferred embodiment (type 3.2), the system contains the following components: (i) hexagonally shaped lower basins (1) and upper basins (2) arranged directly one above the other, with the lower basin (1) having a slight effect due to the required air supply (24) has a larger floor plan than the upper basin (2), (ii) a siphon line (3) with vacuum pump (9), Turbine (10), gate valve (13), suction pipe (25), gear (23) and generator (11), (iii) 54 pumps (12).

In a further preferred embodiment (type 4.2) the system contains the following components: (i) hexagonally shaped lower basins (1) and upper basins (2) arranged directly one above the other, the lower basin (1) being a slightly larger one because of the required air supply (24) Floor plan as the upper basin (2), (ii) three siphon lines (3) each with a vacuum pump (9), turbine (10), gate valve (13), suction pipe (25), gear (23) and generator (11), (iii) 54 pumps (12).

In a further preferred embodiment, at least two of the systems according to the invention are combined in one assembly. The number of systems possible per assembly is in principle unlimited. The number of systems per assembly is preferably between 2 and 100, particularly preferably 16 of the aforementioned systems of type 4.2 are combined in one assembly (see FIG. 4/10).

Another preferred embodiment (type 5.2; Figure 8/10) is designed to be particularly space-saving and is constructed as follows: In relation to the planned possible uses of type 5.2 with attachment to building facades of any kind, system type 5.2 has a very slim design. The upper basin is tubular and adapts to the building facade. The entire technical unit, including the basin, is located underground. This means that type 5.2 can also be used in residential areas - not in a disruptive manner. The advantage of the system is that the pumps (36), but also the pumps (12) of the systems 2.2 to 4.2, operate relatively noiselessly under water and the gears (23) and the generators (11) can be largely encapsulated.

The size of the siphon line depends on the power used or the number of pumps (12) or (36), so that with a more powerful turbine

(10) and the corresponding generator (11) a higher energy gain can be earned. The second possibility is to undertake a greater height of fall through a construction pit or an elevation of the system, which with the same number of units and a consequent higher internal power consumption of the pumps, but still provides a higher energy gain. This variant is reserved for the areas that have a corresponding building site or for systems with a greater height above the building site that allow or allow an increase in industrial halls or according to the development plan in commercial or industrial areas. If the systems are increased, the boundary conditions for the performance of the pumps according to Sections 4a) or 4b) of this application must also be checked.

The present invention also relates to a method for operating the self-sufficient hydropower plant according to the invention, which comprises the following steps:

Closing the gate valve (13);

Vent the siphon line (3) and fill it with water either through

(i) pure vacuum ventilation of the siphon line (3) or

(ii) water inflow to the drain siphon section (6) by means of a centrifugal pump (14) followed by vacuum venting;

Control of the venting of the siphon line (3) by signal via sensor (15) and management;

Opening the gate valve (13) after venting the siphon line (3) by signal from float (16) or by water level switch (16); and switching on and continuous and synchronous increase in the output of pumps (12) or (36) up to the maximum output. increase in radiance

The turbine (10) is preferably not, as is customary in water power, over

Needle nozzles but driven by the much more efficient flat jet nozzles (42).

This mode of operation is particularly advantageous in system type 5.2 (Figure 8/10). In numerous experiments, the inventor was able to use a measuring device (37) and a force sensor (38) to prove that the flat jet nozzle (graph (40)) is used worldwide and without exception in hydropower

Needle nozzle (graph (39)), a between 25% and 30% higher jet force resp.

Surface technology are used. A flat jet nozzle generates an intense and even jet of water and is insensitive to it

Pressure fluctuations. The geometry of the outlet opening of the flat jet nozzle (42) creates a flat and fan-like spray jet with a uniformity

(10) can be used to increase performance. The size of the middle sheath

(44) depends on the angle of curvature of the turbine blade (41), the The height of the central cutting edge typically corresponds to between 40 and 60% of the blade width. The two deflection angles of the central cutting edge are to be adapted tangentially to the spray jet. At at least one of the two lateral ends of the turbine blade (41), the latter can also contain a shaped delimitation (45) for deflecting the amount of water flowing on the blade. If it is present, such a delimitation (45) is preferably attached to both lateral ends of the turbine blade (41) (see schematic illustration of delimitation (45) in FIG. 10/10). The limitation (45) can advantageously have the shape of a Pelton bucket (https://de.wikipedia.org/wiki/Pelton- turbine). However, other shapes are also possible. Usually one of the boundaries (45) takes up about 1-20% of the width of the entire airfoil, preferably 2-10%. Furthermore, the height of the central cutting edge (44) is typically less than or equal to the dimension of the boundary (45). In summary, the flat jet nozzle (42) results in a significantly higher jet force for the incoming amount of water (43) compared to a needle nozzle. This is particularly true when the impact force of the water can act on an identical large impact surface of the turbine blades (41) and no untouched surfaces adversely affect the efficiency of the turbine.
