Definitions

  • the invention relates to a method and a device for extinguishing fires Objects or in facilities.
  • plants with a operated gaseous extinguishing agent Especially in systems where the extinguishing agent Water causes great damage, for example data centers or the like.
  • other objects, such as rotogravure machines are equipped with a gas extinguishing system protected. Fire extinguishing systems powered by water are only used in such cases used less often.
  • extinguishing agent suitable for such objects or facilities as an extinguishing agent
  • Extinguishing gas such as carbon dioxide
  • the resulting one Delay in extinguishing leads to high damage in the event of fire and thus to longer ones Business interruptions.
  • the starting point for fires is often a deflagration of e.g. explosive substances or mixtures.
  • Ignition source for an ignition of these substances can Machine equipment electrostatic discharge or warming up of bearings be.
  • a fireball is created if it is under high pressure standing extinguishing gas is released.
  • the striking fireball spreads quickly and thus endangers the people working in the area to be protected.
  • the large and rapid fire spread due to the fireball firing out leads to high damage to property. Associated with this is the spread of toxic fire and Flue gases, which continues to cause environmental damage.
  • the invention has for its object a stationary fire extinguishing system with a to create gaseous extinguishing agents that are delay-free or even Delayed triggering of the extinguishing system in the event of fire without environmental influences Danger to people with high environmental protection guaranteed.
  • This object is achieved with an inert gas extinguishing agent stored under high pressure, that with 30 to 60 bar pressure as an extinguishing gas cone freely on the object to be protected is applied or introduced into the device, with a closed water mist curtain forms a central area in which there is no delay or delay Erection of the water mist curtain that introduces gaseous extinguishing agents.
  • the water mist curtain with its central area forms the effective area of the gaseous extinguishing agent which, after formation of the curtain, is conical in it Effective range is introduced.
  • the curtain prevents the fireball from spreading because he removes thermal energy from the fireball and the gaseous extinguishing agent within the Water mist curtain captivates. It prevents the extinguishing gas from flowing out quickly.
  • the fireball runs into the water mist curtain, losing in the cooling acting extinguishing water in energy. At the same time, this causes very fine atomization Extinguishing water suppresses and leaches out toxic flue gases. Through this rapid binding of the convection and radiant heat emitted by the flame in an effective fire spread is prevented by the water mist curtain.
  • the water mist curtain is in the millisecond range (without delay) or delayed and only then the extinguishing gas also in the Millisecond range (without delay) or delayed in the central area of the Curtain is introduced and thus the above-mentioned advantage can result fire fighting, and thus the extinguishing agent is initiated without delay become.
  • the fire extinguishing system according to the invention with combined gas and water extinguishing agents guarantees optimal personal, object and environmental protection with a smaller overall extinguishing system and lower total amount of extinguishing agent.
  • a stationary fire extinguishing system 1 is used to extinguish fires on objects 2 (FIG. 1) or used in devices 3 (Fig. 5).
  • the fire extinguishing system 1, according to Fig. 1, for Protecting object 2 consists of the combination of a high-pressure gas extinguishing system 4th with a low-pressure, medium-pressure or high-pressure water spray extinguishing system 12.
  • the high-pressure gas extinguishing system 4 consists of high-pressure gas bottles 7 with Bottle valves 8 from which a gas line 6 with a control device 9 originates.
  • a gas extinguishing nozzle 5 at the end of line 6, which is in the center or on the side of object 2 is provided.
  • the high-pressure water spray extinguishing system 12 consists of a line 15 with a ring line or stub 14, attached to the fine spray mist nozzles 13 are. These mist nozzles are in accordance with patent applications P 44 07 779.2 and P 44 07 780.7 trained.
  • the ring line or stub 14 with the fine spray mist nozzles 13 are arranged so that the nozzles 13 surround the gas extinguishing nozzle 5 in an almost annular manner or are arranged in front of or behind the angular range of the gaseous extinguishing agent.
  • the water line connected to the ring line 14 can be connected to a line, not shown Water source, e.g. B. connected to a water network with a pumping station.
  • a high pressure water reservoir 16 is provided on which Line 15 is connected to a control valve 17.
  • the one on a floor 23 Set up object 2 is a fire detector (smoke, flame, heat) 26 assigned to the an alarm line 37 is connected to a fire alarm control panel 25. Assigned to this are two detectors 27 and 28, which are independent of one another via control lines 29 and 30 are connected to the control device 9 or the control valve 17.
  • the fire detector 26 reports the fire to the fire alarm control panel, which is initially via the Detector 28 activates the high pressure water spray extinguishing system 12 in which the control valve 17 is opened. As a result, the extinguishing water flows to the nozzles 13 and occurs there as Cone 20 out.
  • the nozzles are arranged so that overlapping cones 20 occur which form a closed annular water mist curtain 18.
  • This curtain forms a free central area 22 in the area of the gas extinguishing nozzle 5 into which the extinguishing gas is introduced.
  • the fire alarm control panel controls the detector 27 High pressure gas extinguishing system 4 in which, via the control device 9, the cylinder valves 8 be opened and thus the extinguishing gas flows to the extinguishing nozzle 5.
  • This causes the Extinguishing gas as an extinguishing gas cone 10 and leads the extinguishing gas to the object to be protected 2.
  • the extinguishing gas nozzle 5 (Fig.
  • the gas extinguishing nozzle 5 is connected to the gas line 6 by means of the connector 34.
  • an orifice 36 for pressure limitation and Volume flow limitation.
  • the guide cup 35 ensures a directed omnidirectional jet, with which the extinguishing gas is targeted and limited in speed to the desired area is applied conically.
  • the object 2 to be protected is of a housing or a capsule 11 surrounded. The object to be protected is thus free in the room. That too protective object can also be arranged between two walls 24, as in FIG. 3 and 4.
  • extinguishing nozzles 5a are in series above or arranged laterally of the object 2.
  • the water mist curtain is here as a flat curtain 19 formed by flat rays 21.
  • the use of omnidirectional nozzles is also possible.
  • the other two extinguishing systems 4 and 12 are constructed as described in Fig. 1. It is also required to protect overall facilities 3 (Fig. 5).
  • both the gas extinguishing nozzle 5 and the fine spray mist nozzles 13 are placed in the device 3.
  • the mode of operation is the same as described in FIG. 1.
