Definitions

  • the present invention relates to energy recovery installations, in particular to installations aiming to recover energy originating from low-temperature heat, for example from an isotopic separation plant. uranium and transfer this recovered energy into electrical energy.
  • Isotopic separation of uranium is currently carried out by passing part of the flow of uranium hexafluoride through porous barriers called diffusers.
  • This operation requires pressurization, carried out using compressors which compress the uranium hexafluoride before directing it towards the diffusers.
  • These compressors require cooling by circulation of water, the temperature of which is raised, at the outlet of the cooling circuit, to relatively low values, of the order of 90 to 120 ° C. in general.
  • This cooling water is sent to an exchanger from which it leaves at a lower temperature, adjusted for its reuse, the energy coming from this cooling can then be recovered thanks to the exchanger and supply for example a turbine connected to an alternator. .
  • the present invention relates to an energy recovery installation at low temperature with a higher efficiency than that of installations known hitherto.
  • the installation of the invention is of the type with two loops each comprising an exchanger-evaporator, at least one expansion turbine providing external work, and a condenser, installation in which the two exchanger-evaporators are traversed in series by the liquid.
  • the two loops use identical fluids working at different pressures and temperatures in each loop, each downstream evaporator or condenser being adjusted to a pressure and temperature lower than that of the upstream evaporator or condenser, considered in the direction of circulation of the hot liquid or the coolant.
  • references 1 and 2 designate two conventional exchangers operating by evaporation of an auxiliary fluid, such as ammonia taken from the same tank 25.
  • the amonl exchanger has an upper inlet 3 of water from the circuit for cooling the compressors of the separation plant, and a lower outlet 4 for water cooled to a determined temperature T 1 .
  • the downstream exchanger 2 has a water inlet 5 and a water outlet 6 at a determined temperature T 2 . Water enters in 3 at a relatively low temperature T 0 , of the order of 95 ° C. for example.
  • the outlet 4 and the inlet 5 are connected to each other, the exchangers 1 and 2 therefore being supplied in series with the cooling water coming from the compressors.
  • the water circulates in each of the exchangers 1 and 2 through a bundle of tubes 7 connecting two end plates 8, 9.
  • the water outlet temperatures (T 1 , T 2 ) of each of the exchangers 1 and 2 are regulated by means of a temperature measuring device (respectively 10 and 11) acting on a regulating valve (respectively 12 and 13) of the evaporation fluid.
  • Each of the upstream 1 or downstream 2 exchangers is part of an auxiliary fluid working loop comprising respectively a steam turbine 18 or 19, a condenser 20 or 21, a circulation pump 16 or 17 and a control valve 12 or 13
  • Each of the loops is filled with the same ammonia fluid by means of feed pumps 23 or 24 from the same tank 25.
  • the ammonia circulates, in a conventional manner, according to the following cycle:
  • the ammonia issuing, in the liquid state, and at low temperature from the condenser 14, 15 is brought to a high pressure using a pump 16, 17 and introduced, through the regulating valve 12, 13 into the lower part of the exchanger 1, 2 in which it circulates between the heating tubes 7. It is thus heated, vaporized, then superheated, and feeds, at the outlet of the exchanger 1, 2 a steam turbine 18, 19 After its expansion in the turbine, the steam is sent to the condenser 14, 15 where it is brought back to the liquid state by the in through a cooling coil 20, 21 with water circulation.
  • the water circulation cooling circuits 20, 21 of the two condensers 14, 15 are also arranged in series.
  • the energy recovery circuit of the invention makes it possible to obtain a non-negligible increase in yield compared to the circuits known hitherto.
  • the series connection of the water circulation circuits both in the exchangers and in the condensers makes it possible to obtain a more rational use of the steam produced and a reduction in the pumping power for the water supply to the condensers , so that the energy recovery gain is increased.
  • the upstream exchanger 1 operates at an ammonia pressure higher than that under which the downstream exchanger operates.
  • the intermediate temperature T 1 is advantageously chosen as being the median temperature between the inlet temperature T 0 corresponding to that of the water at the outlet of the compressors and the outlet temperature T 2 , the value of which is fixed either by optimization of the recovery system either by requirements from the separation plant.
  • the pressure and temperature of the upstream condenser 14 are slightly higher than those of the downstream condenser 15, which allows an improvement in the distribution of the detents between the two machines, and which also makes it possible to obtain a less humid vapor at the exhaust. of the higher pressure turbine 18.
  • the invention finds its use for energy recovery.
