Definitions

  • Such spaces i.e. spaces that, due to their location, geometry, Equipment and / or expansion of an escape from fires or consequences of fire (smoke, poisonous gases, Heat, vapors, etc.) or only inappropriately allow it is considerable Dangers to life and limb connected.
  • Such spaces (hereinafter referred to as “danger areas” are) for example tunnels, rooms with locks, cellars, high floors in High-rise buildings, rooms in (nuclear) power plants, clean rooms, laboratories etc.
  • Tunnels and other danger areas are often provided with shelters (niches), they. usually do not offer active ventilation and / or cooling. Staying in such Shelters can therefore mean that people are only protected for a certain amount of time and are in mortal danger if the fire spreads or the consequences of a fire.
  • the invention has for its object to a system suitable for hazardous areas create an active ventilation and cooling system and keep harmful substances away.
  • DE-A-40 25 804 describes a device for the supply of cooled air in a room, whereby the cold flow outlet of a vortex tube into the room leads.
  • Vortex tube is arranged in the room. Neither will discloses where the hot flow outlet leads.
  • Much more only an air conditioning system for supply is cooled Air described in a room with a vortex tube.
  • Vortex tubes are supplied with compressed air.
  • the functioning of the vortex tube is briefly described below:
  • a stream of compressed air is fed tangentially into a pipe.
  • This compressed air flow is divided into two Partial flows on: A partial flow exits heated via a static throttle at one end of the pipe, the other partial flow exits cooled via a static orifice at the other end of the pipe.
  • Fig. 1 is the basic Circuit of such a system described:
  • shelters 2 for accommodating groups of people
  • Shelters 3 to accommodate groups of 4 or individuals, depending on how the spatial conditions in the tunnel are.
  • shelters 2 or 3 Vortex tubes 5, from which cooled air exits into the shelters. This cooled air serves for breathing and cooling people or the shelter.
  • a barrier to the Danger area e.g. door
  • the compressed air is supplied via a line 6.
  • This compressed air is over a Compressed air station provided, which consists of a wind boiler 7, a compressed air compressor 8 and if necessary, there is a compressed air dryer 9.
  • the compressed air station can, however, in the tunnel itself also (preferably) be set up outside the tunnel.
  • the pipeline 6 should be insulated (e.g. double-walled with mineral in between Thermal insulation, possibly also melt basalt to increase the temperature resistance be used).
  • the wind boiler 7 should be designed so that it is large enough. Compressed air for the Provide the duration and volume of the largest fire to be assumed.
  • the compressor 8 would be relatively small; moreover, in the event of danger, it is not inevitable Compressed air compressors must be started, i.e. the life-saving air is in one static system and is not subject to the reliability of moving components and Machine groups.
  • the compressed air line 6 can be used from both sides of the tunnel entrance a corresponding compressed air device can be supplied. Likewise, the compressed air line 6 can be divided into several sub-lines to avoid damage to a pipeline To maintain pipe reserves.
  • FIG. 2 A more precise circuit of the vortex tube system is shown in Fig. 2.
  • the vortex tube 5 is with the compressed air line 6 is supplied from the air boiler 7, which in turn from Compressed air compressor 8 and possibly a compressed air dryer 9 is supplied with compressed air.
  • the Wind boiler 7 is provided with a sump drain 10, via the condensed water vapor can be discharged outside.
  • a pressure relief valve ensures that the pressure in 7 does not rise unacceptably and at Exceeds the maximum pressure blows through an outlet 11. Compressed air humidity can condense in a condenser 9 and then discharged through a drain 12 become. Possibly. it is possible and even sensible to have a small partial flow of the orifice 13 To drain compressed air continuously via the compressed air compressor 8. It is both a regular Functional control possible, on the other hand the compressed air compressor 8 is kept “warm” what Corrosion prevents prolonged standstill. To prevent compressed air from escaping when the To prevent compressed air compressor 8, a check valve 14 can be used.
  • the compressed air line 6 enters the shelter 2, 3 and opens into a tap (in Fig. 2 as Ball valve shown).
  • the tap 15 is normally, i.e. if the shelter is not occupied or operated, closed. People who visit the shelter in the event of danger, can open the tap 15 (e.g. via a lever or a chain, which are clearly identified and act only in one direction or via footboard that is connected to the tap 15 so that when entering the shelter via a bar, chain or the like opens automatically).
  • the compressed air entering the swirl tube 16 tangentially occurs on Warm air outlet 17 heated via the throttle 19 and cooled at the cold air outlet 18 via the Fade out.
  • the heated partial flow is through the hot air outlet 17 through the wall of the Sheltered area to the danger zone (again a positive pressure drop), the cooled air at the cold air outlet 18 is available to people in the shelter.
  • the compressed air can also be used to operate an emergency power generator To enable lighting of the shelter.
  • the partition between the shelter and the danger zone can be made of refractory or fire retardant material with good thermal insulation and is preferably as solid Wall with door / gate or only as door / gate.
