Definitions

  • the present invention relates to the cooling and purification of the gases leaving an electrolysis installation, such as an installation intended for the industrial production of hydrogen and oxygen by electrolysis of water under high pressure and high temperature.
  • the gases extracted such as hydrogen and oxygen in the case of the electrolysis of water, leave gas-liquid separators, or "degassers", at temperature high, often above 100 ° C, and charged with water vapor and impurities in the form of aerosols constituted for example by traces of potash.
  • degassers gas-liquid separators, or "degassers”
  • These gases must therefore, at the outlet of the degasser, be cooled, so as to condense the water vapor that they contain, and purified.
  • German application DE-B-1 006 401 describes an installation for the electrolysis of pressurized water provided, above each degasser, with a tower for washing the extracted gases.
  • a gas washing tower is an empty tower equipped with sprayers.
  • the reference 7 designates a degasser for electrolysis installation, of the gravity type and in the example considers as described in the French patent application n ° 79-03550 of the plaintiff.
  • the degasser 7 is provided with an inlet 76 for mixing a liquid electrolyte, anolyte or catholyte as the case may be, and gas, oxygen or hydrogen respectively, of at least one upper pipe 5 for outlet from gas alone, an outlet 77 of degassed liquid electrolyte, and complementary separation cells 72, three in number in the example considered.
  • the hot, gas-charged electrolyte enters the degasser 7 via line 76, through cells 72, via passages 711 of the inlet plate 71 and passages 731 of the outlet plate 73, then spring degassed through line 77 to the electrolyte return circuit.
  • the bubbles of coalesced gas on the internal faces of the cells 72 escape through the lateral orifices 741, and come to accumulate at the upper part of the degasser 7 from which they leave via the outlet pipe 5.
  • the pipe 5 opens into an enclosure 1 placed above the separator 7, and containing a volume 3 of pure or demineralized water.
  • the volume of water 3 is moreover traversed by a cooling circuit constituted by a coil 2 in which circulates cold water, at a temperature of around 20 ° C. to fix ideas, which helps to give the volume of water 3 a temperature of around 30 ° C in the example considered, sufficient to cause the condensation of the water vapor contained in the gas bubbles escaping through the upper outlet 52 of the pipe 5.
  • the gas bubbles passing from the outlet 51 of the degasser 7 to the enclosure 1 therefore pass through the volume 3 of pure and refrigerated water. At the time of this crossing, they are washed of their impurities and cooled so as to condense the water vapor which they contain, the condensate obtained being added to the pure water already constituting volume 3. They then leave perfectly purified by an outlet pipe 4 located at the top of the enclosure 1.
  • the level of pure water in enclosure 1 is kept more or less constant thanks to a pressure regulator, not shown, located on the circuit 4 of the outlet gases, and acting on a valve, not shown, controlling an inlet 11 demineralized water in the enclosure 1. Furthermore, the return of the condensation water to the electrolysis circuit is effected by at least one pipe 6 connecting the interior of the enclosure 1 to the interior of the degasser 7, from the upper inlet 61 to the lower outlet 62 of the said pipe, which moreover ensures a good pressure balance between the enclosures 1 and 7.
  • the invention finds its main use in the industrial production of hydrogen and oxygen by electrolysis of water under pressure.
