  • the present invention deals with a plant for recovering energy from a fluid flow, in particular water, exploiting the positive and negative pressure values according to the difference in level of water accumulation basins arranged along the hydraulic circuit composing the plant.
  • Object of the present invention is solving the prior art problems, by providing a plant for recovering energy from a fluid flow which is extremely efficient, easily manufactured and with reduced cost.
  • the plant of the present invention is substantially composed of a fluid column placed under negative (static) pressure, from which liquid is taken through a pump and is transferred in the falling part with a positive pressure, using a compensating circuit composed of various elements which allow sending to the energy generator a fluid flow with a positive thrust composed of the sum of the forces generated in the various steps of the path travelled by the fluid.
  • the plant of the present invention is substantially composed of two columns placed at the same positive pressure, which create the conditions under which the fluid flow passing by the various elements composing the plant reaches the energy generator with a positive thrust, benefiting from the sum of forces generated in the path travelled by the fluid.
  • Figure 1 shows the following components:
  • Big fluid reserve basin which is on the ground surface, where volumes and surfaces are determined by the needs of the plant.
  • This basin can be both artificial, and natural, like a lake, river, sea, torrent, etc., where levels, volumes and surfaces will be constant or scarcely variable; this part will always be the part at the lowest level with respect to the other parts composing the plant, such as for example the sea surface level meant as zero.
  • This basin in addition to natural, can also be artificial and built with building material, such as concrete, steel, plastics, glass, etc. The features of the material must be with low friction coefficient to facilitate handling the fluids; in any case, this basin will have to show such technical building features as to allow a resistance to stresses of the forces acting outside and inside it.
  • This basin could be open or totally closed: this choice will be dictated by the needs of the type of plant, when working either with natural pressure or with artificial pressure.
  • D) Big tap (gate) which can be found above the cover of the reserve (1), and is used to put in natural balance the fluid mass in the plant when the plant operates under natural pressures.
  • Fluid rising tube - This building element is sized depending on operating needs and amount of fluid which has to be moved through it; the geometric shapes of this part can change depending on technical and operating needs.
  • This part can be made of different types of material, suitably with low fluid friction coefficient, and extremely low fluid sliding speeds, and building features which are resistant against forces operating inside and outside this part.

  • Suction tube this component, connected to the pumping system, is completely immersed into the previous component, the compensating reserve (10); the position of this component is parallel to the part in which it is immersed; its sizes are proportional to the exchange amounts; this part will have a greater internal flow speed.
  • This tube can be geometrically built with sizes which make its suction easier; the materials to be adopted need low resistances to fluid flows and good insulation from external fluid.
  • this part of the plant can eb used with any type of pump or fluid exchange system, provided that suction creates values equal to negative pressure values which can be found in the exchange chamber when it is under static conditions (before starting the pump) ; setting these pressures equal facilitates the fluid exchange from suction to exhaust under positive pressure; the pump exhaust is connected insulated from influences due to the release compensator.
  • This part which accompanies the fluid flow, is suitably made in a conical shape, in which flow is unified in a bunch of sizes suitable for the exiting amounts and for increasing the flow speed and increase the dynamic dragging; the building materials for this exchange or pumping system are advised with low friction coefficients.
  • Compensating chamber which is used as exchange point of pressure, volumes, density between pump outlet and release compensator, in which, when the dynamic fluid acceleration process is triggered, the gas contained in the upper part, which exceeds the fluid level is compressed or decompressed in such a way as to allow the pump to freely exhaust and that the fluid flow is free in its fall and can benefit from gravity and acceleration induced by the pump; these components need geometries, volumes and surfaces suitable to the amount of exiting fluid, and their building features must support external and internal forces.
  • Backup gas chamber it is a gas reserve which is used to guarantee the release of fluid under free fall, this due to the difference in density between fluid and gas itself, creating the necessary space or advancing the fluid when exiting the pump.
  • Duct which is used to accompany the fluid downwards along the turbine (26) direction it can have different shapes, such as squared, cylindrical and conical, preferably conical for a better efficiency; it must be made of a rigid material, possibly coated with materials with low friction coefficient .

  • the plant is loaded with fluids regularly through its entry tap (6), suitably made for this operation.
  • the closure of the tap (20) above the turbine chamber (25) is ensured, and, once having set the correct level for the plant fluids using the suitable taps for adjusting the fluids, such as tap (C) for the big reserve (1) level, tap (8) for the exchange chamber (7), tap (13) for exhausting the suction tube (11) and pump (12), and the exchange chamber with tap (15) when filling, complying with the levels (2) already preset and provided for its operation, one makes sure that all parts where fluid flows has no conditions which impair the correct operating cycle, and, once the plant has been regularly loaded, its operating procedure starts.
  • the suitable taps for adjusting the fluids such as tap (C) for the big reserve (1) level, tap (8) for the exchange chamber (7), tap (13) for exhausting the suction tube (11) and pump (12), and the exchange chamber with tap (15) when filling, complying with the levels (2) already preset and provided for its operation, one makes sure that all parts where fluid flows
  • the fluid which is in the exchange chamber (7) has the higher negative pressure value.
  • the pressure value starting from the exchange chamber (7) upwards towards the big reserve (1) will go from a negative pressure up to a pressure equal to the big reserve (1) one, namely the atmospheric pressure.
  • the same pressure value can also be found in the suction tube (11), which is completely immerses into the fluid contained in the compensating reserve (10) which communicates with the same level of the big reserve (1), starting depending on the pressure of the big reserve (1) up to its maximum height which is under negative pressure (-) .
  • the pump (12) To create a situation in which advantage can be had of the dynamic movement of the fluid, the pump (12) must be actuated, which creates, from the big reserve (1) till the entry of the pump (12) through the suction tube (11) , a dynamic negative pressure condition, equal to the previously statically created static negative pressure condition in the exchange chamber (7).
  • fluid exiting the pump (12) assumes a positive pressure condition, which divides the influence of the negative pressure entering the pump (12) from the positive one exiting, and consequently changes the pressure condition of the descent column from point 12 (pump) till point 26 (turbine) , including the pressure condition of the backup gas chamber (17).
  • the amount of outgoing flow and the pressure condition created by the pump (12) must be compensated with the accompanying cone (16) which extends almost till the collecting cone (16) perpendicular with the column (19), with the compensating chamber (14) and the backup gas chamber ( 17) which are connected through the duct (28) and is above the plant level.
  • the big reserve (1) and the backup gas chamber (17) have the same pressure value because they are connected through the duct (21) which is driven with respective taps (21a) and (21b) .

  • Turbine which is placed in the chamber (l 1 ) and which can be of different construction types, such as Kaplan, Fancis, Peltron, and other types of turbines which can be found on the market or of a particular application design .
  • Tube which connects the turbine (2 1 ) outlet with the pump (4 1 ) inlet this tube can have different types and geometric shapes suitably made for this purpose, and must be built with material possibly with low friction coefficient.
  • Pump or fluid exchange system this part of the plant can use any type of pumping or fluid exchange system, provided that the pressure generated at its outlet has values which are equal to or greater than the positive pressure values which can be found in the chamber (5').
  • Discharging tube for the pump (4') which is joined to the pump (4') and extends till above the fluid level (E) , which can be found in the chamber (5'); it can have different geometric shapes, and is built with a material possibly with low friction coefficient, which guarantees the resistance to internal and external forces.
  • Fluid rising tube it is connected in the lower part with the chamber (5'), and in the upper part with the connection chamber (8'); its height determines the positive pressures inside the plant, and can be made with geometric shapes at will, which comply with the plant operating requirements. Construction materials must have a low friction coefficient and must guarantee the resistance to external and internal forces.
  • Connecting chamber it is placed in the upper part of the plant, and connects the rising fluid flow of the tube (7 1 ) to the descending flow of the tube (9'); this part of the plant has twp types of fluid, namely the circulating fluid between rise and descent, and the gaseous fluid which remains in the upper part of this chamber.

Once having regularly filled- in the plant, complying with levels (A) , (B) and (C) provided for its operation, the plant is ready to operate.
  • the pump (4') will have the gravity as single opposing force, which will oppose from the pump (4') outlet till the tube (6') outlet, in the chamber (5'), and not the whole column of the rising tube (7'), thereby benefiting of the maximum amount of fluid which the pumping system can move.
  • the pressure created by the pump (4 1 ) will be summed to the pressure of the turbine (1') chamber due to the column height of the descent tube ⁇ 9') , with the result of enabling the exchange of fluid taken in the chamber turbine (1') and discharged in the pump discharge chamber (5').
  • Gas contained in the chamber (l 1 ) enables the pump suction and the exhaust of the turbine ⁇ 2') , since pressure and volume conditions being found in the chamber (1') will balance the pressure and volume of the chamber (5 1 ), since the gas density increases in a very low percentage when the pressure increases.
  • the fluid moved by the pump (4') joins the fluid contained in the chamber (5 1 ) : the pressure differential induced by the pump (4 1 ) will be summed as acceleration factor in the fluid movement towards the turbine (2'), through the connecting chamber (8 1 ) and the descent tube (9') ⁇
  • the diameter of the rising tube (7') will be sized depending on the pressure difference produced by the pump (4 1 ): this to obtain that the amount of fluid moved towards the rising tube (7') balances the amount of fluid crossing the descent tube (9 1 ) down to the turbine (2'); since the sliding speed of fluid in the rising tube (7') depends only on the pressure difference generated by the pump (4'), while in the descent tube (9') the fluid speed depends on the acceleration due to gravity, it will therefore be necessary to size such tubes appropriately with different computations.
