Definitions

  • the invention relates to a working as a foam extinguisher portable or rollable fire extinguisher that is pressurized Extinguishing foam generated.
  • the first compressor air foam devices were already in the early thirties built as fire extinguishers. In the 1930s was a portable pump with flange-mounted compressor for generating pressure foam built.
  • CAFS extinguishing systems work in such a way that the air required for foam generation by a compressor with a discharge pressure of approx. 7 to 10 bar the extinguishing agent flow fed.
  • the extinguishing agent consists of water with added Foaming agent.
  • By supplying the compressed air the flow of extinguishing agent conveyed by a pump this added additional energy. This results in significantly better throwing distances and an extremely homogeneous Foam bubble structure with previously unknown adhesive properties.
  • CAFS is a further development of the foam extinguishing process with Water with the addition of Class A foam (wetting agent).
  • CAFS can both with fire class A (solid fires) and with fire class B (liquid fires) can be used.
  • a CAFS system has so far consisted of the components of a fire-fighting centrifugal pump for water supply, air compressor for Compressed air generation, and foam proportioning system for admixing Foam agent with mixing valve and associated control technology.
  • the object of the invention is a portable or rollable fire extinguisher to create that with compressed gas foam consolidation works according to the known CAFS system and achieved corresponding advantages in use.
  • the invention solves the stated object by the claim 1 specified fire extinguisher.
  • Advantageous embodiments of the Invention are the subject of the dependent claims.
  • the so generated Foam has a droplet spectrum with a smaller particle size.
  • the foam generated can therefore better in the fuels penetrate, stay there longer and intensify the wetting the extinguishing effect.
  • the extinguishing device according to the invention is very successful with fabrics of fire classes A and B. used.
  • propellant gas is metered in.
  • the resulting compressed gas-hardened foam is due to its homogeneous foam bubble structure a greatly improved Adhesion to the fire materials.
  • the drawing shows the fire gun in side view with the supply lines and a mixing device; the remaining part of the extinguisher with extinguishing agent container, compressed gas bottle and fittings is not shown.
  • the extinguishing agent container is a pressure container trained with water with the addition of a foaming agent is filled.
  • a compressed gas cylinder is known per se Coupled to the extinguishing agent container and with appropriate fitting provided.
  • the (also not shown) fitting of the compressed gas bottle designed so that pressurized gas from the pressurized gas bottle when starting up of the extinguisher not only in the extinguishing agent container, but also also passed into the supply line of the extinguishing agent to the extinguishing gun becomes.
  • the drawing shows the extinguishing gun 1 with the spray nozzle 2 and the extinguishing agent hose coming from the extinguishing agent container 3.
  • a mixer tap in the form of an appropriately trained T-connector 4 installed, which also a Compressed gas hose coming from the compressed gas cylinder fitting 5 connected.
  • the fire extinguisher according to the invention preferably in the high pressure range between 25 and 35 bar.
  • that is Device according to the invention based on a known High pressure water or foam extinguisher according to the patent DE 196 46 562 realized, which is a user device that can be refilled on site with over one Compressed gas cylinder quick coupling is.
  • the device according to the invention takes place in that the Pressurized gas from the pressurized gas bottle not only into the extinguishing agent container to expel the extinguishing agent under high Pressure, but also directly via the mixer valve 5 in front of the extinguishing gun 1 into the extinguishing agent line is initiated, a strong mixing of the extinguishing agent with the compressed gas serving as the propellant. It is clear that the Introducing the compressed gas into the extinguishing agent line via the Mixing valve, as shown, before the beam interruption or Regulation device of the extinguishing gun 1 takes place.
  • the admixture of compressed gas in the extinguishing agent line, that is into the extinguishing agent flow, directly in front of the spray gun 1 is done in a carefully metered manner with exactly one on top of the other coordinated pressure and volume flow ratios. Their attitude takes place (not shown) on the compressed gas cylinder fitting.
  • the Extinguishing agent flow rate is at least 19 L / min and one Foaming number of at least 7.5 can be achieved.
  • the device according to the invention is an extremely adhesive Formed foam that achieves the same result as a foam generated by a fire truck with CAFS equipment.
  • the individual droplets of the Extinguishing agent accelerated considerably more, which led to an increased Penetration depth into the fire material leads to a considerable increase in efficiency during the deletion process.
  • This effect is at a working pressure of the extinguisher in the Range of 25 to 35 bar is particularly pronounced.
