Definitions

  • the present invention relates to a method and an associated apparatus for recovering energy from engines.
  • the technical problem which is posed, therefore, is that of providing an apparatus and a method for recovering energy from engines for devices of various kinds, which results in an adequate and effective energy gain at the end of the operating cycle.
  • this device should have small dimensions, be easy and inexpensive to produce and assemble and be able to be easily installed at any user premises and also in combination with already existing engines.
  • FIG. 1 shows a schematic diagram of a first embodiment of the energy recovery apparatus according to the present invention.
  • FIG. 2 shows a schematic diagram of a second embodiment of the energy recovery apparatus according to the present invention.
  • an engine 20 operates a primary shaft 1 , which in the example according to the figure is rotating, but may be also be operated displaceably.
  • the engine 20 in the example shown consists of a pneumatic engine comprising a pair of cylinders 21 which house movably inside them a respective piston 22 moved by compressed air A 1 supplied by a primary energy source 10 comprising a compressor 11 and a tank 12 .
  • a storage tank 23 (shown in broken lines in the figure) is arranged between the line 110 and the cylinders 21 of the engine 20 , said tank being supplied by means of pipes 23 a connected to the respective cylinders 21 .
  • said recovery apparatus 100 comprises at least one tank 120 (three in the example shown) containing water; each tank 120 has an inlet 121 for the pressurised air supplied by the line 110 , at least one inlet 126 for the water and at least one, outlet 122 for the water which is pressurised by the air supplied to the tank.
  • the pressurised air inlet 121 is regulated by a controlled intercept valve 121 a.
  • an outlet valve 124 for the pressurised air contained inside the tank 120 is also arranged in the region of the air inlet valve 121 , said air being in turn also able to be recovered and, for example, being stored in a tank 124 a for subsequent use, resulting in further energy recovery.
  • the pressurised water from each tank 120 is supplied to a line 130 for supplying a turbine 140 situated at a higher level than the tank 120 so that, when there is no thrust due to the pressurised air A 2 , the water head is in equilibrium with the free surface being positioned in the vicinity of the inlet to the turbine 140 .
  • outlet of the tanks 120 is in turn regulated by a controlled valve 122 a.
  • the turbine 140 starts to move as a result of the thrusting action of the pressurised water and in turn causes rotation of a secondary shaft 2 which may be used to operate auxiliary devices of various kinds.
  • the shaft 2 operates an air pump 40 able to pump pressurised air either to the primary tank 12 or directly to the pneumatic engine 20 by means of a duct 41 which, as shown in broken lines, may also be connected to the inlet pipe 110 of the first tank 120 .
  • the secondary shaft 2 may also operate an electric motor 50 , the shaft 51 of which may be connected to various user devices.
  • the turbine operating water once all of its potential energy has been used up, is discharged via pipes 141 either directly into the tank 120 or, in a preferred embodiment as shown, into a tank 150 provided with outlets 151 for the return of the water to the tank(s) 120 .
  • valve 125 situated between the water return pipes and the tank 120 is envisaged, said valve being able to open the delivery for the time need to restore the level of water inside the tank 120 itself.
  • valves 121 a , 122 a and 125 will be synchronized both with each other and with the cycle time of the pistons 21 so that, during the thrust phase of the piston, the air inlet valve 121 a is closed and the air discharge valve 124 and in sequence the inlet valve 125 for the water which could not enter with the tank still under pressure are opened.
  • FIG. 2 it is also envisaged being able to achieve further energy recovery by means of an apparatus according to the invention with a dual stage.
  • duplicating the recovery apparatus 100 by connecting via a pipe 1110 the breather valve 124 of the first stage to the inlet valve 121 a of the pipe 121 supplying the compressed air to the first tank 120 .
  • the compressed air recovered from the first stage can be used to operate a second shaft 2 of a second turbine 140 , operation of which constitutes a total gain since it is obtained only by components with operation by means of recovery from the first stage.
  • the pump 40 is an air pump which sends compressed air either to the cylinders 21 or to the storage tank 12 supplying them.
  • the secondary shaft 2 may operate an electric motor 50 bypassing or in parallel with the pump 40 , in keeping with the values of the residual energy available.
  • duplicating the recovery apparatus 100 by connecting via a pipe 1110 the breather valve 124 of the first stage to the inlet valve 121 a of the pipe 121 for supplying the compressed air to the first tank 120 .
  • the method comprises a further step consisting in:
