Definitions

  • the invention relates to a working as a foam extinguisher portable or rollable fire extinguisher that generates compressed gas-solidified foam.
  • CAFS Compact Air Foam System
  • CAFS extinguishing systems operate in such a way that the air required for foam generation fed through a compressor with a discharge pressure of about 7 to 10 bar the extinguishing agent flow.
  • the extinguishing agent consists of water with added Foaming agent.
  • CAFS is a further development of the foam extinguishing process with water with the addition of Class-A-Foam (wetting agent).
  • CAFS can be used both for fire class A (solid fires) and for fire class B (liquid fires).
  • a CAFS system has hitherto consisted of the components of a centrifugal fire pump for pumping water, an air compressor for the generation of compressed air, and a foam mixing system for adding foam with a mixing valve and associated control technology.
  • CAFS systems are currently being installed firmly in fire fighting vehicles.
  • the object of the invention is to provide a portable or rollable fire extinguisher that works with compressed gas foam consolidation according to the known CAFS system and achieves corresponding advantages in use.
  • US-A-4,981,178 discloses a portable fire extinguisher with a flameproof extinguishing agent container, a compressed gas cylinder for pressurizing the extinguishing agent container for expelling the extinguishing agent, and an extinguishing agent, which is connected via a pressure-resistant extinguishing agent hose to the interior of the pressure medium container.
  • the extinguishing device according to the invention with CAFS properties many improvements can be achieved.
  • the foam thus produced has a smaller particle size droplet spectrum.
  • the generated foam can therefore penetrate better into the flammable substances, stays there longer, and increases by the wetting the extinguishing effect.
  • the extinguishing device according to the invention can be used with substances of fire classes A and B with great success.
  • propellant gas is metered. Due to its homogeneous foam bubble structure, the resulting gas-pressure-strengthened foam has greatly improved adhesion to the fires. Especially on vertical surfaces or overhead, the foam adheres for a long time and can therefore be used much more effectively than water or foam from previous fire extinguishers. Experiments have shown that the compressed gas-solidified foam from the device according to the invention even adhere to glass for a long time.
  • the drawing shows a side view of the extinguishing gun with the leads and a mixing device; the remaining part of the extinguisher with extinguishing agent tank, cylinder and fittings is not shown.
  • the not shown extinguishing agent container is designed as a pressure vessel which is filled with water with the addition of a foaming agent.
  • a compressed gas cylinder is known per se Manner coupled to the extinguishing agent tank and provided with appropriate fitting.
  • the (also not shown) fitting of the compressed gas cylinder is designed so that compressed gas is passed from the compressed gas cylinder at startup of the extinguishing device not only in the extinguishing agent container, but also in the supply of extinguishing agent to the extinguishing gun.
  • the drawing shows the extinguishing gun 1 with the spray nozzle 2 and the extinguishing agent from the extinguishing agent 3.
  • a mixing valve in the form of a correspondingly formed T-fitting 4 is installed, in which also coming from the compressed gas cylinder fitting compressed gas hose. 5 connected.
  • the fire extinguisher invention preferably operates in the high pressure range between 25 and 35 bar.
  • the device according to the invention based on a known high-pressure water or foam extinguishing device according to the patent DE 196 46 562 is realized, which is a refillable by the user in place device with a quick coupling ankuppelbarer compressed gas cylinder.
  • the compressed gas is introduced from the compressed gas cylinder not only in the extinguishing agent container for expelling the extinguishing agent under high pressure, but also also on the mixing valve 5 immediately before the extinguishing gun 1 in the extinguishing agent, a strong mixing of the extinguishing agent with the compressed gas serving as propellant gas. It is clear that the introduction of the compressed gas into the extinguishing medium line via the mixing valve, as shown, before the Strahlunterbrechungs- or regulating device of the extinguishing gun 1 takes place.
  • the admixture of compressed gas in the extinguishing agent line, ie in the extinguishing agent flow, directly in front of the spray gun 1 takes place in a carefully metered manner with exactly matched pressure and volume flow conditions. Their setting is done (not shown) on the compressed gas cylinder fitting.
  • the extinguishant flow rate should be at least 19 L / min and a foaming rate of at least 7.5 should be achieved.
  • an extremely adhesive foam is formed, which achieves the same result as a foam produced by a fire truck with CAFS equipment. Due to the additionally supplied before the extinguishing gun in the extinguishing agent flow compressed gas, the individual droplets of the extinguishing agent are accelerated considerably more, resulting in an increased penetration depth into the fire and thus to a considerable increase in efficiency during the deletion process. This effect is achieved particularly pronounced at a working pressure of the extinguisher in the range of 25 to 35 bar.
