Definitions
- the present invention relates to an inerting method for reducing the risk and extinguishing fires in closed rooms and an apparatus for performing the method.
- the volume of the room is 6500 m 3.
- steel bottles with a capacity of 80 1 are used. In inert gas extinguishing systems, these are pressurized to 200 bar filled, which is currently the current standard size due to the maximum load capacity of the fittings available. At 200 bar cylinder pressure, 80 liters hold 18.3 kg of nitrogen, for example, which then results in 16 m 3 of nitrogen in the relaxed state at 1 bar ambient pressure.
- the oxygen content in the enclosed space is reduced to a certain basic inerting level of, for example, 16%, and in the event of a fire, the oxygen content is further increased to a certain full inerting level, for example 12 vol .-% or less.
- a basic inertization level of 16 vol.% Oxygen concentration means no danger to people or animals, so that they can still enter the room without any problems.
- the full inertization level can either be set at night when no people or animals are entering the room, or directly in response to a reported fire. At 12 vol.% Oxygen concentration, the flammability of most materials is reduced to such an extent that they can no longer ignite.
- the advantages of the method according to the invention are in particular that the number of containers required for the oxygen-displacing inert gases in the event of a fire is significantly reduced. This significantly reduces the overall costs of the fire prevention and extinguishing system.
- a smaller pressure relief device is required structurally, since in the event of a fire only a smaller gas volume has to flow in within the short time available, for which a relief must be provided for in the construction.
- a device for carrying out this method which initially has the following components: an oxygen measuring device in the room to be monitored; a first plant for the production of the oxygen displacing gas or for the extraction of oxygen from the room to be monitored; a second system for the sudden introduction of an oxygen displacing gas into the room to be monitored; and a fire detection device for detecting a fire parameter in the room air.
- a controller is provided, which in
- the first system for producing the oxygen-displacing gas or for removing the oxygen, and which, depending on a detection signal from the fire detection device, emits a full inerting signal to the second system.
- This device ideally realizes the connection of the method according to the invention to a fire detection device.
- the control according to the invention for emitting the basic inerting signal and the full inerting signal takes into account the particular circumstances of the room to be monitored, the basic inerting level of which was previously calculated according to the size and type of the room.
- the inerting process preferably contains the following two further process steps, which are carried out before the first process step, the lowering of the oxygen content to a certain basic inerting level: according to this further development, the oxygen content in the room to be monitored is first measured and then takes place in a second
- Process step lowering to the basic level of inertization depending on the measured oxygen value.
- the inerting method thus adapts to certain leakages in the room by classic regulation of the oxygen content in the room to be monitored. - 5 -
- a detector for fire parameters is preferably integrated into the method, which emits a signal for full inertization in the event of a fire.
- an aspirative fire detection device is understood to be a fire detection device that actively draws in a representative part of the room air at a number of points via a pipeline or duct system and then feeds this part of it to a measuring chamber with a detector for detecting a fire parameter.
- fire parameter is understood to mean physical parameters that are subject to measurable changes in the vicinity of a source fire, for example the ambient temperature, the solid or liquid or gas content in the ambient air (formation of smoke in the form of particles or aerosols or steam) or the ambient radiation.
- the method can be carried out in a particularly advantageous manner if the basic level of inertization takes place by machine production and subsequent introduction of oxygen-displacing gases or else by machine oxygen removal. This is feasible in that it can be reduced to
- Basic inertization level more time is available, so that a gradual reduction of the oxygen content in the corresponding room by a machine is sufficient.
- an introduction of oxygen-displacing gases into the enclosed space is preferably provided for the rapid attainment of the full inerting level, it being possible in principle for all inert gases to be used here.
- These can advantageously be provided in gas containers because even in larger rooms, the volume to be filled between the basic level of inertia and the level of full level of inertia is no longer a problem.
- mechanical production of oxygen-displacing gases for example by means of a nitrogen machine, is of great advantage since the gas containers which are responsible for full inerting can also be refilled after use.
- the introduction of the oxygen-displacing gases takes place as a function of the oxygen content measured in the closed space. This ensures that only the amount of gas required for full inertization is supplied.
- the oxygen measuring device for carrying out the method is integrated in the detector housing of the fire detection device, where the air flow monitoring device is also arranged.
- the oxygen-displacing gases are preferably produced mechanically by a nitrogen machine or the like in order to achieve the basic level of inertization. It has already been mentioned that the gas containers responsible for the full inertization can be refilled in an advantageous manner if they have been emptied.
- a closed room with normal room air with the usual oxygen content of 21 vol.% Must be monitored.
- the oxygen content in the enclosed space is reduced to a certain basic inerting level by introducing nitrogen from a nitrogen machine.
- the oxygen content in the room to be monitored is continuously measured.
- the target specification was previously calculated based on the properties of the room and its equipment with computer equipment and the like.
- An aspirative fire detection device which is equipped with a detector for fire parameters, continuously draws in representative portions of the room air via a pipe or duct system and feeds these portions to the detector for the fire parameters. If a fire parameter is detected and with the usual
- the oxygen measuring device continuously checks whether a lower threshold value of an oxygen concentration which is hazardous to health has been reached. If this is not yet the case, the nitrogen machine continues to receive the basic inerting signal and continues to flood the room with nitrogen. If the health-endangering threshold value is reached, a query is made as to whether the conditions for night operation or the conditions for day operation are to be established.
- the full inerting signal is sent to the nitrogen machine, whereupon further oxygen displacement takes place depending on the measured oxygen content, - " until the extinguishable concentration specified for the room and the materials contained therein is reached If, however, the room is to be entered, the oxygen measuring device is used Oxygen concentration kept at a non-hazardous value of about 16%.
