  • An object of this invention is to provide apparatus for providing motive power.
  • apparatus for providing motive power comprising first and second columns of liquid, the liquid in the second column being substantially the same as in the first column but containing a finely divided material to increase its specific gravity relative to the liquid in the first column, means for reducing pressure above said columns, whereby liquid height in the respective columns is different, means for causing liquid from the first column to overflow into the second column, means for converting energy from resultant movement of liquid into motive power and means for returning the liquid to the first column.
  • the means for reducing pressure above the columns preferably comprises a vacuum pump acting on a defined space communicating with both columns -and means for isolating the pump from the space when a desired pressure reduction therein is reached.
  • the means for causing overflow of liquid from the first to the second columns preferably comprises thrust applied by one or more pumping means associated with either or both of said columns. It is preferred to keep the finely divided material substantially evenly dispersed throughout the liquid in the second column.
  • liquid agitating means may be associated with the second column. Such agitating means may be mechanical, such as the or a pumping means associated with the second column.
  • agitating means such as an auger
  • external means such as magnetic means
  • a pump may also provide thrust for causing overflow of the liquid in the first column into the second column. That may allow the second column to be lowered with respect to the first column to provide a greater drop height for the overflowing liquid.
  • the means for converting energy from liquid movement into motive power is preferably a turbine.
  • the turbine may be located at any point in the apparatus where movement of the liquid only can be utilised.
  • the turbine may be located in the second column for falling liquid to impinge directly on rotating blades thereof.
  • the turbine may be located in a line returning liquid to the first column or a reservoir therefor.
  • the turbine may be situated in the first column itself to be driven by liquid rising in that column.
  • the second column preferably has a second limb communicating with the main column from just below the turbine to a lower part of the column, which limb may include said agitating or pumping means to provide circulatory motion for the liquid in the second column and hence even dispersion of the finely divided material therein.
  • the preferred finely divided material is one that can be readily separated from the liquid in the second column so that the liquid only can be returned from the second column to the first column.
  • the finely divided material may be of a magnetic substance such as magnetite or ferrosilicon, so that magnetic separation means may be used to remove or hold back the finely divided material from the liquid being returned to the first column.
  • mechanical separation means may be used such as filter means or a settling tank.
  • the finely divided material is preferably of a particle size that will pass a 0.25 mm mesh.
  • settling vessel needs careful consideration as the rate of suspension separation may determine the maximum system liquid flow, and hence energy available to the turbine.
  • a cone shaped vessel is adequate but settling rates can be improved by installing suitable baffle plates to induce longer flow paths for the suspension, and hence longer residence time for the separation phase to take place.
  • the use of magnetic material, such as magnetite or ferrosilicon allows conventional magnetic recovery apparatus to be utilised.
  • a further method that can be employed with magnetic material which is energy efficient, is to direct the suspension flow within the settling vessel through a weakly magnetic field, which has the effect of agglomerating the individual magnetic particles together, into heavier clusters, which causes them to sink faster, speeding up the separation process.

  • the limb 22 includes a dense media circulating pump 28.
  • the first column 10 and liquid tank 12 contain water.
  • the second column 20 contains a suspension of magnetite or ferrosilicon in water. The contents of the second column 20, having a higher specific gravity than the contents of the first column, do not rise as high as the liquid in the first column.
  • the vacuum chamber 30 is connected to a vacuum pump 31 whereby the pressure above the two columns can be reduced in order to bring the height of liquid in the first column close to overflowing into the vacuum chamber 30 and on to the second chamber.
  • the vacuum pump 30 is valved so that it can be shut off when a desired pressure reduction is reached.
  • the magnetite In operation, the magnetite is kept in suspension by gentle agitation produced by the pump 28 in the limb 22 of the second column 20.

  • the potential and kinetic energy of the falling water is extracted via the turbine and converted into useful rotational motive power.
  • the water discharging from the turbine into the second column 20 will alter the static balance of the dense media system causing the liquid to rise and flow through the outlet 13 into the liquid tank 12, the separation unit 40 retaining the magnetite for return into the suspension in the second column.
  • water flow can be induced by further reducing the pressure -in chamber 30 so that atmospheric pressure acting on tank 12 forces water into the chamber 30.
  • the apparatus has a liquid reservoir 50 open to atmosphere. From the reservoir 50 extends a column 52 that includes a valve 54. The column 52 rises vertically before connecting with a vessel 56. The vessel 56 has a vacuum pump 58 connected thereto via line 60 that includes a valve 62.

  • an overflow column 72 that includes a turbine 74.
  • the column 72 leads to the liquid reservoir 50.
  • Water containing magnetite circulates through column 70 to the vessel 56 where it mixes with water in vessel 56 supplied from the reservoir 50 via column 52.
  • the mixture travels down column 64 into the settling vessel 66, where the magnetite settles out and is recirculated.
  • Substantially clear water from the top of the settling vessel overflows into column 72 to drive the turbine 74 and restock the reservoir 50.
  • a partial vacuum is induced in the vessel 56 by the vacuum pump 58 and then valve 60 closed.
  • the pump 68 is then started inducing a gentle flow of magnetite laden water around its circuit as described above.
  • the pressure in the vacuum vessel 56 was reduced sufficiently to allow atmospheric pressure, when acting on the open surface of the liquid in the settling vessel, to counterbalance back pressure in columns 64 and 70. That enables energy consumption of the pump 68 to be reduced to the amount required to maintain the magnetite in substantially full suspension and overcome fiction and leaving losses.
  • the magnetite is circulated for a sufficient time to ensure substantially complete suspension and achievement of a desired specific gravity.
  • Valve 54 is opened allowing atmospheric pressure to act on the water in reservoir 50, forcing the water up column 52 into vacuum vessel 56.
  • the height of column 52 measured from the water surface of reservoir 50 to its inlet into vessel 56 is designed to enable the differential pressure between the atmosphere and the partial pressure in vessel 56 to impart sufficient pressure on the water in column 52 to overcome friction and leaving losses.
  • the water now enters vacuum vessel 56 at a higher point than the magnetite suspension enters and mixes therewith.
  • the mixture of water and magnetite suspension entering column 64 will now have a lower specific gravity than the magnetite suspension entering vessel 56 from column 70.
  • Atmospheric pressure acting on the surface of vessel 66 is now able to support this lighter mixture to a greater height than before, causing the suspension water mix to rise, or back up in vessel 56, to a height proportional to its reduced specific gravity.
  • the entry point of the water from column 52 is designed to coincide with the top of the suspension/water mixture in vessel 56 to ensure compatible pressures. No additional energy is required by pump 68 to maintain the suspension circulation under these back up conditions.
  • the height of the freefall of water through column 72 to the turbine 74, and the resultant energy that can be produced from this apparatus can be calculated by reference to: ⁇ 1.
  • the vacuum drawn in vessel 56 which determines the overall operating height of the system.
  • the specific gravity of the suspension circuit which determines the height ratios of the suspension and water circuits.
  • the ratio of volume of suspension to volume of water which determines the height of the back up in vessel 56, and so governs the height and volume of water discharging into the turbine from the settling tank.
  • the suspension circuit is established as previously described, with the suitable vacuum being drawn in vessel 56 to allow the atmospheric pressure to fully support the circulating suspension.
  • the differential pressure required to support the suspension will be greater than that required to support the water in column 52, after valve 54 is opened, by a ratio equivalent to the ratio of the ?"ispension specific gravity to the water.
  • This arrangement enable the overall apparatus height to be reduced by approximately one third, giving significant savings in capital and installation costs, and allowing applications for the system in situations where available height is limited.

Abstract

Un appareil générateur de force motrice comprend des première (10) et deuxième (20) colonnes de liquide. Le liquide dans la deuxième colonne est essentiellement identique à celui dans la première colonne mais contient un matériau finement divisé qui augmente son poids volumique par rapport au liquide dans la première colonne. Un dispositif (31) réduit la pression au-dessus des colonnes de sorte que les niveaux de liquide dans chaque colonne soient différents, un dispositif (18) provoque le déversement dans la deuxième colonne du liquide contenu dans la première colonne, un dispositif (29) convertit en force motrice l'énergie générée par ce déplacement du liquide et un dispositif (13, 40) retourne le liquide à la première colonne.
