Definitions
- the invention relates to an arrangement for extinguishing fires the preamble of claim 1.
- the object of the invention is to provide an arrangement for extinguishing fires, in which the dangers or damage from extinguishing for people and material are as small as possible.
- the arrangement should be a simple one Have structure and be inexpensive.
- a room 1 has two entrances 2, 3 and is one in the corner area Cover with a cavitation nozzle 4 to 7 and also with a central on the Ceiling of the room (not shown) arranged sensor 8 for smoke or Provide fire alarm.
- the room 1 and the entrances 2, 3 have different Built-in components, see also FIG. 2
- the airbag 10 has the corresponding Corner areas 35 and the spaces 36 auxiliary bags 12 to 16 on the air bag 10 and the auxiliary bags 12 to 16 are cut so that - different from the schematic representation in Fig. 2 - all gaps and spaces that in the schematic representation are shown visibly, filled in or at least are almost filled.
- the airbag 10 and 11 and the auxiliary bags 12 to 16 are made by a stationary Air pressure network - not shown - or by a pyrotechnic gas generator - also not shown - supplied with air or inflated.
- a solution can also be provided in which the air bags 10; 11 each with a gas generator are provided, which then also feeds the auxiliary bags 12 to 16.
- the cavitating nozzle or cavitation nozzle 4 to 7 has according to FIGS. 4 and 5 a level 19 on the mouthpiece 20. So that is already at relatively low pressure Cavitation creates.
- FIG. 5 Another, equivalent effect training is shown in Fig. 5, after which Mouthpiece 21 an aperture 22 is provided.
- the Injection law ", ie the time-dependent drop diameter distribution can easily be controlled via the injection pressure profile applied to the nozzle 4 to 7. For example, deliver dirty "start and stop profiles larger drops 27 corresponding to the areas 43, 44 than that stationary "design part of the injection pressure profile with the area 42.
- the cavitation nozzle 4 to 7 has a relatively high Efficiency and a more uniform drop spectrum in at least two Areas 42; 43, 44 of drop size 26, 27.
- Handheld devices for object protection can, according to the invention, be small and therefore light and be built handy. Its construction is very simple: the water is there the cavitation nozzles 4 to 7 in a flexible sack (not shown), which of Is acted upon externally by the compressed gas. So that the not shown Extinguishers can be used regardless of their orientation.
- the air bags 10 to 16 are inflated and blocked then the entrances 2, 3; d. that is, they prevent the fire from spreading further 50 or a spread of the flue gases as well as the supply of atmospheric oxygen. Afterwards or in parallel with this, room 1 in which it burns and / or in the actual source of fire 50 the heat of reaction from a water mist from larger and smaller drops of water 26, 42; 43, 44 withdrawn. The water mist or the drops 26, 27 is generated by the nozzles 4 to 7, the deletion process is triggered by the sensor 8 or an alarm system. The possibly still existing Residual fire can be caused by fire extinguishing personnel using water mist from handheld devices be fought.
- Water should be used as the extinguishing medium. Water is non-toxic and chemical neutral, has a heat capacity and a heat of vaporization and is always avaliable. Because of its high density, the movement of water drops relatively little influenced by a gas flow.
- the choice of the extinguishing medium is not on clean "water bound. Salt water, drinking water or water with additives, eg with foam additives to cover the source of the fire, can be atomized in the same way as distilled water.
- the air or auxiliary bags 10 to 16 can be provided with an ablation layer be.
- the geometry of these bags 10 to 16 is in accordance with those to be blocked To design cross sections and are with safety, pressure relief valves for the used Gas, such as air, to interpret carbon dioxide.
- Lußsburge of this type are simple under construction and are quick and inexpensive to install or replace. she prevent the supply of atmospheric oxygen to the source of the fire 50 in a simple manner prevent unwanted, uncontrolled and dangerous quickly and safely Spread of smoke and extinguishing gases.
- the inflatable bags 10 to 16 can be inflated with any gas, also with the extinguishing gas. This simplifies the structure of the extinguishing system considerably.
- the extinguishing system according to the invention in accordance with the arrangement described have a minimal impact on people, the environment and machinery. For example, one will be in yours Room 1 trapped person not endangered or damaged by the extinguishing. The pressure level in room 1 remains constant. With this come loads of Installations in vehicles, such as aircraft, watercraft, do not open when extinguishing.
- the arrangement according to the invention is very simple in structure and operation. It is therefore quick to install, use and test anywhere to control. The consequential damage is minor, since room 1 immediately after the Delete can be entered again. The costs, i.e. maintenance, repair and Operating costs are very low.
