Definitions

  • the invention relates to a method for producing artificial snow, with which water in a gas stream with Temperatures are injected below the freezing point of the water and is then applied to the area to be snowed, and to an apparatus for performing this method.
  • the invention is now aimed at the plant engineering Effort and the energetic effort of the known methods further reduce and with small-scale facilities with high mobility snow in those areas respectively Bring sections of a slope where a short-term Supplement is required.
  • the method according to the invention essentially consists in that water is atomized in a closed space, in which liquefied air, air components or their mixtures is injected that the crystals formed a classifier are fed and that a fraction of larger diameter spread on the area to be snowed and a fraction with smaller particle diameter than crystallization nuclei in the closed room.
  • the correspondingly smaller parts serve as crystallization nuclei when they are returned in the closed room and lead to a new growth of the Crystals to the desired dimension of the snow crystals.
  • the method according to the invention is advantageously carried out in such a way that CO 2 snow is added to the fraction having a larger particle diameter at least during a first time interval at the start of the discharge. Additional cold is added to the system by mixed CO 2 snow, whereby CO 2 evaporates without residue into the atmosphere and releases its cold to the surrounding snow during evaporation. This will immediately freeze the underlying aterial areas and thus ensure better insulation, so that more snow can be applied to such a strongly supercooled first layer, which cannot melt again immediately even at relatively high ground temperatures, since there is a corresponding one in between Isolation between the ground and the snow applied above it is formed.
  • the device according to the invention for carrying out this method has at least one blower and lines for the supply of water.
  • the device is essentially characterized in that a first chamber is connected to a first fan, in which water nozzles are arranged to form an aerosol, that the first chamber is connected to a further chamber, in which nozzles for atomizing liquid air and / or liquid nitrogen and nozzles for the atomization of further water are arranged in such a way that the further chamber is connected to a classifier, from which a fraction with large crystals can be discharged via a lock and is connected to a further blower via a line, and that one further conduction to the classifier is excluded, via which crystals with a smaller diameter can be returned to the first fan and the first chamber.
  • the design is advantageously such that a mixing chamber is arranged between the discharge of the classifier and the further blower, into which a line for the supply of CO 2 opens, in which CO 2 is expanded, the classifier preferably being designed as a cyclone is in which tangentially the line connected to the second chamber opens and that the return line to the first fan and the discharge opening to the second fan are connected essentially axially.
  • the device according to the invention is schematic shown.
  • One opens into a first spray chamber 1 Line 2, through which water can be sprayed, so that in the spray chamber 1 corresponding to gas saturated with water (air, Air gases, components of air in various compositions) is produced.
  • gas saturated with water air, Air gases, components of air in various compositions
  • Fan 3 To transport this mixture is a Fan 3 provided, this gas saturated with water is transferred via line 4 into a further chamber 5, in which cryogenic liquefied air is sprayed with high pressure, for which the line 6 is provided.
  • the aerosol formed evaporates in the warm environment and a corresponding one arises Volume of gas, the system being cooled accordingly becomes. This cold driving process ends when the climb of the outflowing gas volume at constant pressure in Depending on the amount sprayed out, a certain outflow of the Volume falls below.
  • the gas that forms additional water can be injected via lines 7, passes via line 8 into a sifter 9, in which one Phase separation is made.
  • the solid phase is from the Gas phase separated and passes through the return line 10 and the blower 3 again in the cooling chamber, now Water can be injected to the appropriate To train snow crystals.
  • the Sifter or cyclone 9 again a phase separation be made, with primarily larger of smaller crystals are separated and the larger ones Crystals via the rotary valve 11 and the line 12 can be carried out.
  • the particles returned in each case with a smaller diameter serve as nuclei, where there is more atomized water below Training can accumulate correspondingly larger snow crystals.
  • CO 2 snow can be mixed in from a container 13, for which purpose a mixing chamber 14 is provided.
  • the snow is discharged via the blower 15.
