Definitions

  • the invention relates to a method for generating mixed steam.
  • Heat engines are usually operated with steam.
  • liquids are pressurized in a steam generator under high pressure and evaporated by supplying energy. This steam can then be converted into mechanical energy.
  • AT 155744 describes the production of mixed vapor from two or more polar and non-polar liquids which regroup in the liquid phase.
  • the mixed vapor is produced by one or more immediately consecutive expansions and compressions. completely or partially liquefied. Subsequently, the mixed steam is re-evaporated with heat and returned to the working process. The released work can be used to generate electrical energy.
  • WO 2005/054635 A2 discloses a method for generating mechanical energy in a cyclic process with a working medium which consists of two constituents of greatly differing boiling point.
  • the disadvantage here are the high Mischdampftempera- ren and working pressures in the steam generators and the supply and discharge lines. This results in special requirements for the materials used. In order to ensure the operational safety of such systems, they consist of high-quality special steels. They also require intensive and regular inspection by specialized personnel. All this is time consuming and associated with high costs.
  • the object of the present invention is to provide a method for producing mixed steam, with which the amount of energy used, the operating temperature and the operating pressure can be reduced and the efficiency can be improved.
  • the device 10 shown in the single figure consists essentially of at least one mixing steam generator 11, which is provided with a low-pressure boiler 12.
  • the low-pressure boiler 12 has a first pressure chamber 13, in which a first polar fluid 14, for example water, and at least one nonpolar fluid 15, for example benzene, are present in liquid form.
  • This polar fluid 14 is preferably in a higher proportion than da ⁇ s non-polar fluid 15 in front.
  • the mixing steam generator 11 is a schematically illustrated heat exchanger 16, for example, any boiler system assigned. With this heat exchanger 16, the fluids 14 and 15 can be subjected to thermal energy and vaporized.
  • the mixing steam generator 11 is driven at a temperature in the range of 50 0 C to 75 0 C and a pressure in the range of 0.5 to 1.5 bar. In this case, a mixed vapor 17 of the polar fluid 14 and the non-polar fluid 15 is generated. The mixed steam 17 thus generated is collected in a steam pressure chamber 18 of the mixing steam generator 11.
  • the collected mixed steam 17 is then passed through a mixing steam outlet 19 via a pipeline 20 into a subsequent enrichment vessel 21.
  • the supply vessel 21 has a second pressure chamber 22, which is partially filled with a second polar fluid 23.
  • the second polar fluid 23 is chemically identical to the first polar fluid 14, it has only a higher temperature compared to the introduced mixed steam 17.
  • the second polar fluid 23 preferably has a temperature in the range of 70 0 C to 95 0 C, wherein in the enrichment vessel 21, a pressure in the range of 0.5 to 1.5 bar prevails.
  • the pressures in the pressure chambers 13 and 22 are identical. De "r mixed vapor 17 is passed into the second pressure chamber 22 by the liquid present second polar fluid 23rd
  • the mixed steam 17 When passing through the higher-temperature second polar fluid 23, the mixed steam 17 is enriched with polar fluid and collected as enriched, dry mixed steam 24 in a second vapor pressure space 25.
  • the thus enriched dry mixed steam 24 is passed through a mixed steam outlet 26 and a pipe 27 to a heat engine 28.
  • the one in the pipe line 27 adjacent enriched, dry mixed steam 24 is now introduced for compression via an inlet 29 into the working space 30 of a heat engine 28.
  • the enriched, dry mixed steam Due to the compression of the dry mixed steam 24 to a much higher temperature, preferably about 180 0 C, brought. After reaching this temperature, the enriched, dry mixed steam is 24 adiabatically relaxed to wet steam.
  • the relaxed wet steam passes through an outlet 31 into a return line 32 and is returned via a return check valve 33 and a return inlet 34 into the first pressure chamber 13.
  • the steam cycle can start again.
