Definitions

  • the present invention relates to an exchange method of energy in thermal recovery using a fluid vaporizable and involving cooling of said fluid in liquid phase with production of the same fluid at the state of vapor under pressure. It also concerns a installation designed for the implementation of this process.
  • the invention is particularly applicable advantageous for cooling a utility fluid by leaving an industrial unit where it was used, by example, to cool the machines and equipment, or on the contrary as a heating, possibly brought to the state of vapor in a boiler.
  • the vaporizable fluid in question is therefore fluent water, so that in the description detailed which will be given later, we will place our for the essential in the typical case where the vaporizable fluid considered is water, or at least an aqueous vehicle.
  • a fluid such as water, milk, fruit juices, chemical solutions, etc.
  • the invention can find practical in many other situations whenever you want to cool a fluid, such as water, milk, fruit juices, chemical solutions, etc., being in the liquid state at hot temperature, or at least lukewarm, compared to a liquid temperature cold that one wishes to reach to reject it, or, more often to recirculate it at the entrance of the installation in which he warmed up.
  • the installation includes a final condenser, on the steam circuit, which is produced in the form of a surface heat exchanger, that is, hot steam and cold liquid water circulate on either side of a material wall (in general metallic for efficient exchanges through which the transfer takes place thermal.
  • a final condenser on the steam circuit, which is produced in the form of a surface heat exchanger, that is, hot steam and cold liquid water circulate on either side of a material wall (in general metallic for efficient exchanges through which the transfer takes place thermal.
  • the present invention essentially aims to improve conditions thermodynamics and recovery efficiency of thermal energy, to simplify the construction of necessary materials, to reduce costs, both those related to design and installation than those related to operation and maintenance. It applies in particular that we have to recover for recycling the condensed fluid at the state of cooled liquid, or the fluid in gas phase, or both.
  • the invention plans to proceed without the least surface exchanger, for at least one last stage of a thermal energy recovery installation from a vaporizable fluid, causing a partial vaporization of the liquid to be cooled in a vacuum chamber where the vapor is compressed to a pressure vessel, and ensuring recovery of energy by mechanical coupling between two circuits connecting the two speakers which operate in turn repeatedly a mass transfer of the vapor phase fluid from the vacuum vessel to the pressure vessel.
  • a device allowing the implementation of the process which is the subject of the invention therefore comprises two enclosures where different pressures prevail.
  • the organ of mechanical coupling ensuring the transfer is essentially consisting of a double-acting piston cylinder.
  • the piston there separate two complementary rooms which communicate both with the two speakers. Valves admission and refoulement establish a transfer unidirectional from the first to the second enclosure at during the reciprocating movement of the piston.
  • thermal energy is extracted from the hot liquid by mass transfer from the fluid in gas phase, which passes from the first enclosure to the second enclosure, in which this fluid, always in gas phase, is under pressure.
  • the cooled liquid extract from the first enclosure. It can be recycled.
  • the device 1 essentially comprises three parts: two tanks 2 and 3, respectively delimiting one first chamber called vacuum 20 and a second chamber said to be under pressure 30, due to the fact that in operation, maintains the enclosure 20 under vacuum relative to the second enclosure 30, and a fluid transfer member 4 allowing the two speakers 20 and 30 to communicate according to modalities which will be explained below.
  • a hot fluid in the liquid state that to fix the ideas, we will assume to be hot water, or at least lukewarm, from a downstream installation not shown.
  • a pump 210 ensures the circulation of the liquid in the supply line 21. This opens, inside the enclosure 20 by a nozzle spray 22 or similar boom. Water vaporizes partially in the depressed atmosphere. Water no vaporized 23 meets in the bottom of the enclosure 20, however that part of the mass of water injected into found in the form of water vapor 23 '.
  • enclosure 30 of the second tank 3 communicates with the enclosure 20 of the first tank 2, by means of mechanical coupling illustrated by a cylinder 40 in which a double piston effect 41 moves in translation alternately in one direction and in the other, completed by a set of pipes allowing a double mass transfer from the first enclosure 20 to the second enclosure 30.
  • the piston 41 divides, at any time during its stroke, the internal enclosure of the cylinder 40 in two chambers complementary, respectively an upper room 400 and a lower room 401.
  • Upper room 400 communicates with the upper part of the first enclosure 20, by a first line 24 and an inlet valve 42, disposed at the inlet of the upper chamber 400, and with the upper part of the enclosure 30, by a second pipe 31 and a valve exhaust 43 at the outlet of the upper chamber 400.

  • the set of intake valves and exhaust requires fluid transfer unidirectional, from the first enclosure 20 to the second enclosure 30, respectively through each chambers of cylinder 40.
  • the piston 41 is driven by machinery 5, comprising a motor (not shown) driving in turn a flywheel 50.
  • the flywheel 50 is mechanically coupled to the piston 41 by a conventional connecting rod assembly 52 and crank 51, connected by an axis 510, so that the piston 41 performs a repetitive displacement of translations backward and forwardward alternatives inside of cylinder 40.

  • the process and the effects obtained are quite similar to those just described, at the only exception is that upper house 400 plays the role of the lower house 401, and vice versa. It follows that it is lines 25 and 31 which become active in mass transfer from the first to the second enclosure.
  • Line 25 opens into enclosure 20 at a suitable level so as not to suck the liquid at the bottom of tank 23.
  • the shape of its mouth is provided for not to receive a direct flow of liquid, by sprinkling. he is possible, to do this, to give it a form of whistle, the bevelled part of which faces downwards, as suggested by Figures 1A and 1B, or a form similar.
