Definitions

  • the installation in question consists essentially of a siphon, the descending section of which opens and discharges the liquid which passes there at a height greater than that at which the water level of the liquid contained in the supply basin of the riser.
  • the main characteristic of the invention consists in the fact that to emulsify the liquid in the riser, air is used at ambient pressure, preferably at atmospheric pressure.
  • the riser of the siphon can be considered as a particular type of air-lift whose fundamental and novelty characteristics - which differentiate it from traditional pumps of the same kind, and in particular mammoth pumps - consist to operate in a vacuum environment and to use as compressed air, in fact, air at atmospheric pressure.
  • the emulsifier siphon object of the present invention can operate, once it has been primed, on the only condition that in the vacuum chamber into which the riser opens, the operating vacuum is kept constant.
  • an appropriate suction device must transfer outside the air which, after expanding in the riser, has flowed into the vacuum chamber where the riser opens.
  • Wind energy can be used cost-effectively to draw air from the vacuum chamber and discharge it outside.
  • This installation is also characterized by the fact that it is extremely simple to construct; it has no dimensional limits if not to provide, in case of large flows, several pipes to breathe air; it can be operated in series, even with a single vacuum chamber; it has no moving mechanical parts, in particular if it works with a hydraulic vacuum cleaner, while if it works with a wind vacuum cleaner it does not need mechanical transmission means and therefore has an operating cost which coincides convenient- . with the cost of installation.
  • A indicates the riser of the installation constituted by a pipe 1, the lower end of which dips into the supply basin B - for example a lake, a river, a water table and the like - of which the lake is at level h.
  • the upper end of the pipe 1 penetrates inside a vacuum chamber S up to a height hl greater than the height h2 of the bottom of this chamber, but less than the maximum height to which atmospheric pressure could raise, with respect to the depression established and maintained inside the chamber S, the water emulsion -air contained in the riser A, as will be better illustrated later.
  • the vacuum chamber S is constituted by a sealed tank 2 provided with a vacuum cleaner V intended both to create the vacuum at the determined value, and to maintain it throughout the duration of the operating cycle of the system because the water from this emulsion which flows into the chamber S separates from the air by gravity and collects on the bottom of the tank 2, while the released air must be constantly transferred outside by the vacuum cleaner V to maintain the predetermined value of depression.
  • the end of the downcomer C is hydraulically closed as can be seen in the drawing.
  • the vacuum cleaner V intended to create and maintain the desired vacuum in the chamber S
  • the vacuum cleaner V can be constituted by one of the many suitable mechanical devices which are found on the market, it can also be formed , for example, by a Venturi pipe in which the water necessary to obtain and maintain the desired vacuum is flowed from upstream to downstream of the available jump, or even, when the ambient conditions are favorable, by a rotor eolic connected directly to the vacuum chamber.
  • the water contained in the supply basin B tends to rise in the rising column A to a height corresponding to the difference, in meters, between the atmospheric pressure and the pressure existing in the rising column above the liquid body of water.
  • the air at atmospheric pressure can flow through the injector I in the column riser A.
  • the air by flowing through the injector I in the riser in the desired proportion, mixes with the liquid and reduces its density, thus allowing the raising of the emulsion to a height higher than that at which the atmospheric pressure could have raised, compared to the depression existing in the chamber S, the only column of liquid.
  • the riser of the siphon opens into the interior of the chamber S at a height hl greater than the height h2 of the bottom of the tank, but less than the maximum height at which the atmospheric pressure is able to lift, as a function of the depression existing in chamber S, the mixture contained in the riser A.
  • the air separates from the emulsion and the residual water can flow into the use basin D, through the downcomer C, at a level h4 established at a height immediately lower than the height at which the column of liquid which overcomes it can overcome atmospheric pressure, while the air separated from the water in the tank 2 is discharged outside by the vacuum cleaner V to keep the expected vacuum constant in room S.
  • any type of vacuum pump provided that it is capable of ensuring 0.2 atm. as an operating vacuum inside the vacuum chamber S or separator tank.
  • the injector opens inside the riser A at 1.33 m above the level of the water level of the liquid to be lifted.
  • a 30 mm diameter pipe connects the injector to the atmospheric air intake.
  • a valve was provided to allow the amount of air to be supplied to the riser A to be adjusted.
  • the present invention is not limited to the example described, but includes any possible variant of execution.
