Definitions

the invention relates to a compressed air foam fire extinguishing system for a tunnel, in particular a divided into several extinguishing areas road tunnel with arranged outside the tunnel at least at the tunnel ends foam generators, which consist of a supplied with a foaming agent-water mixture and compressed air with the mixer via a Schaumlöschstofftechnisch is connected with foam ejection devices for two-sided firefighting of two adjacent foam generators.
Fires which usually occur in connection with accidents or accidents in a road or railroad or cable car tunnel, are often associated with catastrophic personal injury and material damage due to burning fuels, tires or other hazardous substances. Firefighting vehicles of the fire brigade and rescue vehicles can not reach the source of the fire or much too late. The necessary measures for extinguishing the fire and for rescuing injured persons can not or can not be met on time.
the invention not only relates to vehicle tunnels, but may be applied to any type of elongated canals in which fires may occur, for example, mine tunnels, cable ducts and the like.
Fire extinguishing systems of the type mentioned are known.
the foam generator at the tunnel entrance and exit each comprise a foam generator with an associated with the Schaumlöschstofftechnisch, the compressed air foam delivering Zumischer, to which a compressor, a fire water pump and a Schaumsentner theoryer are connected.
Distributed over the tunnel length are further admixers with foaming agent containers connected to them, which are supplied via a line system with compressed air and extinguishing water from the foam generators arranged at the tunnel inlet and outlet.
the invention has the object of providing a operated with compressed air foam extinguishing agent tunnel extinguishing system so that with reduced equipment cost at each fire a Löschschaummother be provided with maximum extinguishing effect available.
the basic idea of the invention is the automatic setting of a specific initial pressure of the extinguishing foam behind the admixer in order not to fall below a predetermined flow pressure at the extinguishing foam ejection point and to eject a still stable foam with high extinguishing effect.
the formation of a certain initial pressure is achieved by adjustable constriction of the pipe diameter behind the admixer with a control valve, which is controlled by a pressure sensor.
the flow pressure at which a sufficiently stable foam is ejected is preferably 0.6 bar, while the initial pressure is preferably 4 bar.
the foam in combination with a calculated or empirically determined diameter of the foam extinguisher, in which the pressure losses caused by pipe friction are substantially eliminated, the foam can cover long transport routes, at the end of a high-quality stable extinguishing foam with high extinguishing effect is available.
the equipment required for the foam generator is low.
a foam generator 3 is accommodated in each case in a container 2 at the entrance and exit of a road tunnel 1.
the foam generator 3 comprises an admixer 4, to which extinguishing water from a fire water pump 5 and compressed air from a compressor 6 is supplied. From a Schaumsentner electer 7 of the foaming agent enters the admixer 4, in which, depending on the admixed Schaumsentnermenge a more or less wet or dry extinguishing foam is generated.
the individual units of the foam generator 3 are connected to a control unit 8.
the extinguishing foam produced in the foam generators at the tunnel entrance and exit passes through a foam extinguishing line 10, which runs in the installation space 11 of the road tunnel 1, to Schaumausschiquesen 20.
a foam extinguishing line 10 which runs in the installation space 11 of the road tunnel 1, to Schaumausschiquesen 20.
VerDumungsmodule 12 consisting of an admixer 4 and a Schaumsentner essenceer 7, arranged, which are supplied via compressed air lines 14 and fire water lines 15 from the provided at the tunnel entrance and exit foam generators 3 with compressed air and fire water.
the same foam generator 3 may be arranged as at the tunnel entrance and exit. If the tunnel does not exceed a certain length, the additional foam generators 3 or foaming modules 12 can also be completely dispensed with.
the pressure behind the admixer at a certain pipe cross-section and a specific pipe length should be 4 bar and 0.6 bar at the ejection point.
the tube diameter of the foam extinguishing agent line 10 is chosen on the basis of empirical or arithmetical investigations so large that essentially no pressure losses occur through the friction of the foam on the tube inner wall and the pressure losses are essentially determined by the much lower shear losses between the foam bubbles.
