Definitions

  • the present invention relates to an inerting method for extinguishing a fire in an enclosed space (hereinafter also referred to as "target space") in which the oxygen content in the enclosed space is lowered within a predeterminable time to a certain inerting level.
  • EP-A-1 103 286 discloses an inerting plant and an inerting process according to the preamble of claim 1 for fire fighting in a tunnel, wherein the oxygen content in the tunnel is lowered to a certain inerting level which corresponds to an extinguishable concentration of the oxygen content.
  • the document US 6,082,464 A discloses an inertization method in which a first inert gas is introduced into a target space at a first flow rate for a certain time, so that a fire that has broken out in the target space can be extinguished. Furthermore, it is provided in this prior art that subsequently a second Inert gas is supplied at a second flow rate to the target space to keep within the target space, the inert gas concentration at an inerting at which a re-ignition of the fire can be prevented.
  • the document US 2002/070035 A1 discloses a method for extinguishing a fire that has broken out within a closed space.
  • this method it is provided that after the detection of a fire, an inert gas concentration within the closed space is built up abruptly, so as to reduce the oxygen content within the target space to a maximum extinguishing oxygen concentration. Furthermore, it is provided in this known method that, in order to maintain the maximum extinguishing oxygen concentration, the inert gas is fed in a predetermined amount into the closed space.
  • oxygen-displacing gases such as carbon dioxide, nitrogen, noble gases and mixtures thereof
  • the oxygen-displacing gases or inert gases are either stored in steel cylinders compressed or if necessary generated by means of a generator. In case of fire, the gas is then over Piping systems and corresponding outlet nozzles directed to the relevant target area.
  • the time course of a firefighting effected by means of an inertization process is subdivided essentially into two phases, the firefighting phase and the reignition phase.
  • the fire-fighting phase is the phase during which the target space is flooded with an oxygen-displacing gas to achieve a volatile concentration of the introduced inert gas in the target space.
  • the volatile concentration is defined in accordance with VdS as the concentration at which a fire can be excluded with certainty.
  • the extinguishable concentration is below the so-called re-ignition prevention level and, for example, corresponds to an oxygen concentration of about 11.2% by volume in computing areas, electrical switch and distributor rooms, enclosed facilities and warehoused storage areas.
  • the oxygen concentration must reach a so-called backfire prevention level.
  • the re-ignition prevention level is an oxygen concentration at which (re) ignition of materials present in the target space is just precluded.
  • the oxygen concentration of the remindzündverhi matterssulates is dependent on the fire load of the target area and is for example in computing areas, electrical switch and distribution rooms, enclosed facilities and storage areas with assets at an oxygen concentration of about 13.8 vol .-%.
  • the inert gas fire extinguishing system and the inerting process should be designed accordingly.
  • the fire-fighting phase during which the fire in the finish area is completely extinguished, is followed by the so-called reignition phase.
  • the reignition phase is a time period in which the oxygen content does not exceed the re-ignition prevention level, i. for example, above the said 13.8 vol .-%, may increase.
  • the reignition phase has to last more than ten minutes. In other words, this means that the inert gas fire extinguishing system and the inertization process must be designed so that after fire detection the target space is flooded with inert gas so as to achieve an oxygen concentration in the target space within 60 seconds in the target space, and this concentration during the fire fighting phase and the reignition phase is not exceeded.
  • Fig. 1 shows the course of flooding a operated with a conventional inerting inert gas fire extinguishing system on the example of a equipped with a computer equipment target area.
  • VdS guidelines here is the determined from tests anti-ignition level at an oxygen concentration of 13.8 vol .-%; this concentration value is sometimes called "limit concentration”.
  • the extinguishable concentration which is composed of the source material, a space-specific parameter and a safety, is according to the Fig. 1 at 11.2% by volume, and thus by 1.2% by volume, above a dangerous oxygen concentration of 10% by volume for persons and animals.
  • the volatile concentration corresponds to the inertization level of the inert gas fire extinguishing system.
  • the inert gas fire extinguishing system or the inerting method used is designed so that the re-ignition prevention level (13.8% by volume) is achieved by injecting or flooding the target space with inert gas within 60 seconds after the fire detection or initiation of the inertization process. It is envisaged that after reaching the scrubzündverhi regardss stipulates the oxygen concentration is further reduced until the extinguishable concentration or the inerting of the inert gas fire extinguishing system of 11.2 vol .-% is achieved.
  • a further disadvantage is the fact that in the inertization process known from the prior art, there is no possibility, after the end of the firefighting phase, of preventing an early overshoot of the re-ignition level of the oxygen concentration in the target area.
  • this is necessary, for example, if, for example, the tightness of the target area does not correspond to the design value.
  • Such a case is not unlikely since fresh air entries, i. Flow events beyond the boundaries of the shelter, due to, for example, unforeseen leaks in the enclosure components of the target area or due to a malfunction of integrated in the target space ventilation and air conditioning can occur.
  • Such unforeseen leaks can not be taken into account in the consideration of the tightness of the space for the design of the corresponding inertization process and lead in case of fire to an insufficient extinguishing effect of the method used.
  • the present invention is therefore based on the technical problem of specifying an inerting method for extinguishing a fire of the type discussed above, by means of which the most accurate interpretation of inert gas fire extinguishing system used during the inerting process, and in particular as accurate as possible dimensioning of the inert gas to be provided, while maintaining the Fire extinguishing required phase and reignition phase is possible.
  • the advantages of the invention are in particular that an easy to implement and thereby very effective method for optimizing the flooding course of an inert gas fire extinguishing system can be achieved.
  • the reignition phase provided for fire extinguishment is set according to the invention via regulation of the inertization level, it can be achieved that an inerting level set during the fire fighting phase no longer covers the time period of the reignition phase pretends.
  • the inertization level set during the firefighting phase may correspond to an oxygen concentration in the target space which no longer needs to be well below the recirculation-preventive level, as is the case with the conventional inertization processes known from the prior art.
  • any pressure relief flaps provided in the target area can also be dimensioned to be smaller.
  • a specific control range is also provided, in which the inerting level is maintained at the level of re-ignition prevention. This control range is dependent on, for example, the tightness of the target area and / or the design of the inert gas fire extinguishing system or the sensitivity of the sensors used in the target area for determining the oxygen concentration.
  • the inertization level corresponds to the re-ignition prevention level.
  • the dimensioning or design of the inert gas fire extinguishing system very precisely to the target area (density, volume, possible fire hearth materials) to adapt.
  • the regulation of the inerting level in the target area already takes place during the fire fighting phase at the re-ignition prevention level.
  • the storage container for storing the inert gas can be dimensioned significantly smaller or a corresponding system, such as a nitrogen plant for generating the inert gas, be designed correspondingly smaller.
  • the upper threshold oxygen content in the control range is less than or equal to the re-ignition prevention level.
  • threshold value in this context refers to the residual oxygen concentration at which the inert gas fire extinguishing system is switched on again or in which inert gas is again introduced into the target space in order to maintain or reach the inerting level as a setpoint.
  • the upper threshold oxygen content in the control range is spaced from the backfire prevention level, there is some certainty.
  • This safety corresponds to the difference between the re-ignition prevention level and the upper threshold.
  • the control range is limited downwards by a lower threshold.
  • This lower threshold value corresponds to the oxygen concentration at which the inert gas fire extinguishing system is switched off again or the renewed introduction of oxygen-displacing gas into the target space is stopped.
  • the amplitude of the oxygen content in the control range has a height of about 0.2% by volume and preferably a maximum height of 0.2% by volume.
  • the size of the range of the residual oxygen concentration between the on and off threshold of the inert gas fire extinguishing system is about 0.4% by volume, and preferably at most 0.4% by volume.
  • other amplitudes of the oxygen content in the control range are also conceivable here.
  • the regulation of the oxygen content takes place at the re-ignition prevention level, taking into account the air exchange rate of the target area, in particular taking into account the n 50 value of the target area, and / or the pressure difference between the target area and the surroundings.
  • the air exchange rate refers to the ratio of the leakage volume flow in relation to the existing volume of the room at a pressure difference to the environment of 50 Pa. In other words, this means that the air exchange rate is a measure of the tightness of the target area and thus a decisive factor for dimensioning the inert gas fire extinguishing system.
  • the leakage volume flow increases into or out of the measured target area. This increases the fresh air entries in the room and the inert gas losses from the room.
  • the tightness of the respective target space limiting enclosure components is carried out by means of a so-called BlowerDoor measurement. It is intended to generate a standardized overpressure / negative pressure of 10 to 60 Pa in the target area. The air escapes through the leakage surfaces of the enclosing components to the outside or penetrates there. A corresponding measuring device measures the required volume flow to maintain the pressure difference of, for example, 50 Pa required for the measurement. After entering the associated values, an evaluation program calculates the n 50 value of the room, which refers to the generated pressure difference of 50 Pa in a standardized way.
  • the calculation of the extinguishing agent quantity for lowering the oxygen content to the inertization level and for maintaining the oxygen content at the re-ignition prevention level taking into account the air exchange rate of the Target area, in particular taking into account the n 50 - value of the target area, and / or the pressure difference between the target area and the environment.
  • the lowering of the oxygen content is effected by supplying an oxygen-displacing gas into the target space
  • the shaping of the weft curve may be kept correspondingly flatter, so that, for example, not after 60 seconds but only a short time later, about 120 seconds or 180 seconds, the inerting level is reached.
  • the inerting method according to the invention can be used in particular also in target areas which have no solid walls or in which no pressure relief flaps or similar devices can be installed.
  • the inerting process according to the invention in which the lowering of the oxygen content takes place by supplying an oxygen-displacing gas into the target space, it is particularly preferable to regulate the supply of the oxygen-displacing gas as a function of the current oxygen content or the current extinguishing agent concentration provided in the target area.
  • the oxygen content in the room if nitrogen serves as the extinguishing agent.
  • the CO 2 concentration in the target area is preferably measured in order to regulate the supply of oxygen-displacing gas in the target area.
  • the oxygen content in the enclosed space it is particularly preferable for the oxygen content in the enclosed space to be lowered to the specific inertization level within 60 seconds or less. This ensures that the guidelines for CO 2 extinguishing systems prescribed by the VdS are met.
  • the time in which the oxygen content in the target space is lowered to the specific inerting level is greater than 60 seconds.

  • the gas is passed through piping systems and corresponding outlet nozzles in the target area.
  • the advantage of lowering the oxygen content in the target space by introducing an inert gas from a reservoir provided, in which the inert gas is in compressed form, is in particular also to be seen in that by the expansion of the compressed gas in addition to the effect of oxygen displacement also a positive to the Extinguishing effect impacting cooling effect is achieved, since then the expansion of the compressed gas stored compressed oxygen displaced gas directly from the environment and in particular the target space is withdrawn.

This has a very low pressure dew point and a fixed residual oxygen content, which can be continuously monitored.
