Definitions
- the present invention relates to a device for preventing and extinguishing fires in a closed or subdivided into closed sections spatial area, which is referred to in the following "target space", with a buffer reservoir in which oxygen displacing gas is stored under high pressure, a supply pipe system which connecting at least one extinguishing nozzle with the buffer reservoir via a pressure reducing valve, and with a controller for controlling the pressure reducing valve to suddenly initiate the oxygen displacing gas in the target area in stages or in case of fire, with one or more inerting levels in the target space compared to natural Conditions are reduced oxygen content adjustable.
- Such a device is basically known from the prior art, wherein the effect of the so-called "inert gas extinguishing" essentially based on the fact that in closed rooms, which are only occasionally entered by humans or animals and their facilities using conventional extinguishing methods (water and foams), the risk of fire is counteracted by lowering the oxygen concentration in the affected area to an average value of about 12% by volume, at which most combustible materials no longer burn.
- the extinguishing effect is based on the principle of oxygen displacement: normal ambient air consists of 21% oxygen, 78% nitrogen and 1% other gases. for example, by introducing pure nitrogen, the nitrogen concentration in the target Spaces further increases and thus reduces the oxygen content. It is known that a extinguishing effect begins when the oxygen content drops below a value of 15% by volume. Depending on the materials present in the room in question, a further lowering of the oxygen content to the mentioned 12 vol.% Or lower may be required.
- oxygen-displacing gases are usually gases, such as carbon dioxide, nitrogen, noble gases and mixtures thereof, used, which are usually stored in special ancillary rooms or storage rooms in steel bottles.
- gases such as carbon dioxide, nitrogen, noble gases and mixtures thereof
- an inert gas extinguishing system in which the oxygen-displacing gas is stored centrally in a gas cylinder, the individual gas cylinders of the battery being connected via corresponding pipe systems to various extinguishing nozzles in different target areas.
- the inert gas stored under high pressure (200 to 300 bar) in the steel cylinders is reduced to 60 bar.
- 101 21 551 AI provides that the storage problem can be counteracted by reducing the oxygen content to a basic inerting level of about 17% by volume, which is harmless for livewomen, in the target areas.
- the amount of extinguishing gas to be held is reduced to achieve the Vollinert Deutschensni- veaus an oxygen concentration of less than 15 vol .-% for fire prevention and / or extinction, which leads to an improvement of the described storage problems, but still structurally especially premises for the Steel bottles must be provided and the structural complexity for laying the supply lines remains high.
- tunnel refers to all tunnel-like structures, such as mine shafts, tunnels or similar semi-open spaces.
- tunnels are generally not equipped with stationary extinguishing devices, partly because of the relatively high costs of a tunnel
- stationary extinguishing systems there are known in the art approaches to use stationary extinguishing systems in tunnels, which - similar to the known sprinkler systems - the cooling
- the disadvantages of the extinguishing systems known from the prior art for controlling tunnel fires are in addition to the relatively high Installation costs in that the use of water to extinguish existing fires hot vapors arise, which propagate at great speed in the tunnel.
- an inert gas fire extinguishing system for extinguishing fires in tunnels. It is envisaged to store the oxygen-displacing gases used in the inert gas extinguishing technology compressed in special storage containers in adjoining rooms. If necessary, then the oxygen displacing gas is passed through piping systems and corresponding outlet nozzles in the tunnel section in question.
- this known from the prior art fire extinguishing system in turn has the disadvantage that a considerable construction effort is required to equip a tunnel with such a fire extinguishing system or retrofit, as again separate storage spaces for centrally stored oxygen-displacing gas and a widely branched supply pipe system are required.
- the present invention has the object, a device for preventing and extinguishing fires in a closed or subdivided into closed sections target space of the type mentioned in such a way that 'storage of the extinguishable gas to be kept for the fire extinguishing Without the usually custom-designed premises in a simple and cost-effective manner is possible, and that in particular the high structural complexity associated with the installation of the supply pipe system can be significantly reduced.
- Another object of the present invention is to provide a specially designed for tunnel or tunnel-like structures fire extinguishing system, in which can be dispensed with special premises for storage of an extinguishing gas and a complicated and therefore costly supply pipe system.
- the object with respect to the device is in a device for preventing and extinguishing fires in a closed or in closed sections subdividable target area of the type mentioned above achieved in that the buffer reservoir is designed as a high-pressure pipe with a compressive strength> 200 bar and the high-pressure pipe at least one head end portion has a connection for the supply pipe system.
- the solution according to the invention has a whole series of significant advantages over the devices known from fire-extinguishing technology and explained above.
- the fire prevention and extinguishing device according to the present invention which is also referred to as "fire extinguishing system” herein for the sake of simplicity, no separate storage space is required for the buffer reservoir or gas cylinders in which the oxygen displacing gas is is stored under high pressure, since according to the invention the oxygen-displacing gas is no longer stored centrally in a bottle reservoir supplying a plurality of target areas but locally in or directly adjacent to the target compartment itself
- a target space is a tunnel
- it is conceivable to provide the buffer reservoir in the tunnel for example under the road surface, or in an adjacent service pipe another falls during assembly de
- Ceiling or wall breakthroughs provide for installation of the supply pipe system connecting the respective fire extinguishing nozzles to the buffer reservoir.
- both an initial installation and the retrofitting of a building with the fire-extinguishing system are particularly easy to implement and, in particular, very cost-effective to carry out.
- the inventive arrangement of the buffer reservoir and the supply system together with the extinguishing nozzle as a compact assembly in the target space that in case of fire, the expansion energy required by the expansion of stored under high pressure in the buffer reservoir oxygen displacement gas is withdrawn directly from the target space, causing a cooling effect which has another positive effect of extinguishing fires in the target area.
- These pressure vessels have a high pressure storage capacity (300 - 100 bar).
- a high-pressure pipe as buffer reservoir, which has a connection for the supply pipe system at at least one head end section. That connection, which is already present in commercial gas cylinders, can be converted in a particularly simple way for the fire extinguishing system according to the invention.
- both top end sections of the high-pressure pipe to each have a connection for the supply pipe system.
- a symmetrical arrangement of the fire extinguishing system can be achieved, it is possible due to the two-sided connections for the supply pipe system to release the high-pressure oxygen-displaced gas in case of need very quickly in the target area.
- other embodiments are also conceivable here, such as, for example, the use of more than two connections for the supply system when long high-pressure pipes are used as the buffer reservoir. So it is possible to distribute a variety of connections along the pipe.
- the present invention is further based on the consideration that the central
- the buffer reservoir is stored directly in the target area
- the decentralized storage of the extinguishing gas which serves for a multiplicity of target spaces in a conventional fire extinguishing system, is deliberately dispensed with in order to achieve the supply area of a single buffer reservoir to one or more buffer reservoirs At least a few target spaces is reduced, whereby the total size of the individual buffer reservoir compared to the Steel bottle battery assembly is also significantly reduced in the systems known from the prior art.
- the execution of the buffer reservoir, the supply pipe system and the extinguishing nozzles as a compact assembly entails the further advantageous effect that can be dispensed with a complex and especially branched and extensive Zutechnischsrohrsystem- tem, whereby the likelihood of the occurrence of any leaks or leakage points in the piping system is significantly reduced. This increases the reliability of operation of the entire fire extinguishing system, also the costs required for the maintenance of the system can be reduced to a considerable extent.
- the present invention offers the advantage that the supply pipe system, which connects the extinguishing nozzle and the extinguishing nozzles to the buffer reservoir, has a pressure reduction valve. Due to the possibility of integrating the pressure reducing valve in the supply pipe system at the point where a transition from a high pressure area to a low pressure area is to take place, omitted
- the pressure reduction valve is controlled by the controller so that it opens when necessary, wherein the oxygen-displacing gas is introduced from the buffer reservoir in the target area. This makes it possible to set one or more levels of inertization in the target area with reduced oxygen content compared to natural conditions.
- the technical application object is achieved by the use of the fire extinguishing system according to the invention in a tunnel.
- a tunnel with an inert gas fire extinguishing system can be equipped with a particularly low structural complexity.
- a target space is formed in response to a control signal in the tunnel by means of separations, which includes the area affected by the fire of the tunnel, and then in this inerting space by means of the fire extinguishing device according to the invention, the oxygen content is reduced to an inert volume.
- the inventive use of the fire extinguishing system in a tunnel can be achieved in an advantageous manner that the tunnel can be inexpensively retrofitted or retrofitted without special bauli chen effort with a particularly easy to maintain inert gas fire extinguishing system.
- a particularly advantageous development of the present invention is that at least one device for filling or refilling the buffer reservoir with oxygen-displacing gas is provided at the buffer reservoir.
- a device is preferably arranged so that the buffer reservoir in the installed state of the device for preventing and extinguishing fires can be easily achieved from the outside by, for example, a supply line for filling or refilling the buffer reservoir by hand via the device is connected , This makes it possible to make the maintenance of the device according to the invention extremely user-friendly and easy.
- the device for preventing and extinguishing fires has an oxygen-displacing gas generator.
- That gas generator serves to generate the inert gas stored in the buffer reservoir, which is connected to the buffer reservoir by means of the inventive device for filling or refilling the buffer reservoir.
- a gas generator could, for example, be a membrane system with the aid of which air is decomposed in order to produce oxygen-poor air having a residual oxygen content of about 0.5 to 5% by volume.
- Such devices are known from the prior art and will not be explained here. It is conceivable to arrange the gas generator directly in the target area. In a preferred manner, however, the gas generator is provided in a separate space in order to be able to supply a plurality of buffer reservoirs in different target areas with this single gas generator.
- controller also has a
- Has oxygen sensor to measure the oxygen content in the target area and to control the amount of extinguishing agent to be supplied to the target area. That oxygen sensor is used to measure the oxygen content in the target space, wherein a measurement signal is output by the oxygen sensor to the controller, which provides information regarding the set inertization level.
