Definitions
- the present invention relates to an inerting method for preventing a fire or an explosion in an enclosed protective area, in which the oxygen content in the protected area is lowered relative to the ambient air in the protected area.
- Inertization procedures for fire prevention and extinguishing indoors are known from the fire extinguishing technology.
- the extinguishing effect resulting from these processes is based on the principle of oxygen displacement.
- the normal ambient air is known to be 21% by volume of oxygen, 78% by volume of nitrogen and 1% by volume of other gases.
- For extinction or fire prevention by initiating e.g. pure or 90% nitrogen as inert gas further increases the nitrogen concentration in the relevant protection area and thus reduces the oxygen content. It is known that an extinguishing effect starts when the oxygen content drops below about 15% by volume.
- the oxygen displacing gases used in this "inert gas extinguishing technology" are usually stored in special ancillary rooms in steel cylinders compressed or it is a device for generating an oxygen-displacing gas used.Also inert gas-air mixtures with a share of 90%, 95% or 99% nitrogen (or any other inert gas), justify the steel cylinders or equipment for generating the oxygen displacing gas the so-called primary source of Inertgas mecanicerieschstrom. If necessary, then the gas is passed from this source via Rohteieitungssysteme and corresponding outlet nozzles in the relevant protection area. In order to keep the fire risk as low as possible, even if the source fails, occasionally secondary sources of inert gas are also used.
- the reason for a high level of inertization and thus still relatively high oxygen content may be that either people are in the protection area or the access of people to the protected area must be possible, even if an increased concentration of inerting gas Fires should be prevented.
- the continuous influx of inerting gas into the protected area not only leads to higher costs due to the permanent production of inert gas or the discharge of inert gas from primary and / or secondary sources, but also issues that are relevant to the survival and safety of people Protected area touched.
- the present invention is based on the object of the present invention explained Inert deviszentratio further develop so that too high or for certain requirements such as inspection of the protection area by staff too high inert gas concentration can be reliably degraded.
- This object is achieved according to the invention in the inertization method mentioned above in that the oxygen content in the protected area is continuously measured, compared with a threshold value (maximum inerting level) and fresh air is introduced into the protected area if the threshold value (maximum annealing level) falls below the threshold value (unintentional).
- fresh air also oxygen-reduced air with a higher oxygen content than in the protected area to understand.
- the advantages of this invention are, in particular, that an inerting method that is easy to implement and very effective for preventing a fire in an enclosed protected area can be achieved even if the influx of inert gas has occurred uncontrollably due to an error in the inert gas production or inert gas supply system. Fresh air is always available around the protected area to a sufficient extent.
- the disadvantages of the hitherto known apparatuses and methods, which can entail a hazard to humans in the protected area, are clearly avoided.
- the threshold value for the oxygen content, at which fresh air is introduced into the protected area is smaller than the value of the oxygen content of the basic inertization level.
- This type of oxygen content separation makes sense, as the oxygen content of the base inertization level is chosen to avoid fires, but people can still enter the protected area. If the oxygen content continues to decrease as a result of the incorrect excessive supply of inert gas, fires are still prevented, but the stay for persons becomes increasingly dangerous.
- the threshold value for the oxygen content in the protection range is therefore chosen so that it is below the oxygen content of the basic inertization level, but on the other hand does not fall below a dangerous value for humans.
- the inert gas content in the protected area can also be measured.
- the inert gas content is then compared with a threshold value and, when fresh air is exceeded, transferred to the protective atmosphere. richly initiated.
- This method assumes that a direct dependence relationship between oxygen content and / inert gas content occurs in a natural atmosphere. This dependence relationship is known for typical fire avoidance situations.
- the oxygen content in the protected area is measured at several points, each with one or more sensors.
- the advantage of measuring the oxygen content at several points is that even with an uneven concentration of oxygen falls below a. Location already detected.
- Another advantage of using multiple sensors is redundancy. If a sensor is defective or the line to one sensor is interrupted, another sensor can take over the measuring task.
- the signals from the sensors can also be wirelessly transmitted to the control unit.
- the inert gas content in the protected area can also be measured at one or more points, each with one or more inert gas sensors.
- the advantages of multi-site measurement equals the benefits of multi-site oxygen concentration measurement. It is expressly pointed out that a simultaneous measurement of both the oxygen content and the inert gas content significantly increases the safety for persons who are in the protected area.
- the signals of the oxygen sensors or the inert gas sensors are fed to a control unit.
- all electronic components for evaluating the signals of the sensors are combined in this control unit.
- different algorithms for reaction to different gas mixture concentration can be stored in the control unit.
- control unit in an advantageous development, a fresh air supply system on and off.
- the inclusion of the control logic for the fresh air supply system in the control unit also falls under the aspect of a compact design of a central consolidation of all measurement and control signals in an electronic unit.
- the fresh air supply is controlled so that a maximum inerting level is not exceeded.
- the basic inerting level is not undershot. This means that the oxygen concentration within the protected area is regulated even with fresh air supply so that fires are reliably prevented at a basic inerting level. It is important that the fresh air supply is switched on at the latest when a maximum inerting level has been reached, beyond which people who are in the protected area are endangered.
- the control unit monitors a second protection area.
- a fresh air supply system for this second protection area is a fresh air supply system, at least one oxygen sensor and / or at least one inert gas sensor and a range valve for controlling the supply of the inert gas available.
- a maximum inerting level is not exceeded.
- a basic inactivation level is not undercut.
- control unit sets the basic and maximum inertization levels in the different protection areas differently high.
- the oxygen content of the basic inertization level in protection zone Ia may be lower than the corresponding value in protection zone Ib.
- the advantage of such a splitting would be that persons can stay in one area of protection, while in the other area the oxygen content is so low that a stay of persons in this area is not possible. It is conceivable to use such a division in the storage of highly flammable materials in a protected area and of normally flammable materials in another area of protection, which is regularly entered by persons.
- FIG. 1 a schematic representation of the protected area with the associated inert gas sources and the valve, measuring and control facilities as well as the fresh air supply system and the inlet nozzles for the fresh air supply system,
- FIG. 2 shows an exemplary course of the oxygen concentration in FIG.
- Figure 3 a schematic representation of an inerting with two
- FIG. 1 schematically shows, by way of example, the basic function of the method according to the invention, including the associated control and measuring systems.
- Pipes are fat and thick and measuring and control lines are normal and thin.
- the inert gas can be left from the inert gas source 2, through a valve 3a and one or more outlet nozzles 6a in the protection area Ia.
- the inert gas source can be designed in various ways.
- a typical embodiment is to provide the inert gas from one or more containers, for example steel bottles.
- a generator may be used to produce an inert gas (for example, nitrogen) or an inert gas-air mixture.
- a secondary inert gas source which in turn may consist either of compressed inert gas in steel cylinders or of an inert gas-producing generator.
- the concentration of the inert gas in the protection area Ia is regulated by the control unit 4, which in turn influences the valve 3a.
- the control unit 4 is set so that a basic inerting level in the protection area Ia is achieved. This basic inerting level reduces the risk of fires or explosions in protected area Ia.
- inert gas is introduced from the inert gas source 2 via the valve 3a and the inert gas is introduced into the protective area Ia.
- the following mechanism according to the invention is set in motion.
- the control unit 4 measures a too low oxygen concentration via the oxygen sensor 5a, and thus outputs a signal for closing the valve 3a or a signal for turning off the inert gas or inert gas-air mixture producing generator.
- the oxygen concentration in the protected area Ia continues to drop, which is also signaled to the control unit 4 by inert gas sensors 12a can, the fresh air supply system 8a is put into operation, passes through the additional fresh air via one or more fresh air supply inlets 7a in the protection area Ia.
- the volume flow of fresh air is adjusted so that even at full operation of the inert gas-producing system (either made of steel cylinders or as a generator), the inert gas concentration in the protection area Ia can not increase. In this way, it is ensured that a desired oxygen concentration in the protected area Ia is ensured even if the control unit for the inert gas enters the protected area Ia. Thus, fires are reliably prevented, and still can take people without damage in need of protection in the protection area Ia.
- FIG. 2 shows by way of example a possible course of the oxygen concentration in the protected area Ia.
- the oxygen concentration is regulated to a basic inertization level (setpoint), between an upper and a lower set point.
- setpoint a basic inertization level
- the inert gas source is activated and inert gas is introduced into the protected area Ia. Triggered by this introduction of the inert gas into the protected area Ia, the oxygen concentration falls between the times t o and t j .
- the inert gas source is deactivated again.
- the oxygen concentration rises slowly again because, for example, some fresh air enters the protected area due to leaks in relation to the ambient air.
- the inert gas source is reactivated. However, if the inert gas source can not be deactivated due to a defect, the oxygen concentration in the protected area will continue to decrease.
- the maximum inerting concentration which is permitted in protection zone 1 and is still harmless to humans, is achieved. Due to the malfunction of the inert gas system, ie by an unimpeded further influx of inert gas into the protected area, the oxygen concentration would continue to decrease after time t 3 and prevent a safe stay of people in the protected area.
- FIG. 3 shows a further alternative of an inerting system, which in this case has two protective spaces Ia and Ib and area-specific inerting and monitoring systems. has components.
- the protection range Ia is monitored in this case according to the details given in the description of FIGS. 1 and 2.
- a further protection area Ib with associated inerting and monitoring components is shown. These include the valve 3b, the inert gas entering 6b, the oxygen sensor 5b, the fresh air intake 7b and the fresh air supply system 8b.
- the control unit 4 shown in Figure 3 could alternatively consist of two separate control units.
- the two shelters Ia, Ib are separated by a wall 9.
- the control unit 4 shown in Figure 3 could alternatively consist of two separate control units.
- the protection area Ia which is not entered by persons in this case, has a different (higher) inerting level than the protection area Ib, which despite inerting is regularly entered by persons.
- Protection range Ia could, for example, have an inerting level at which the oxygen concentration is about 13% by volume.
- another inertization level of, for example, 17% by volume of oxygen is ensured by the control unit 4 in the protection area 1b. Leakage of the wall 9 can lead to uncontrolled passage of inert gas from protected area Ia to protected area Ib. This is shown in Figure 3 by the directional arrows 10.
- Task of the control unit 4 is the different levels of inerting in the shelters Ia and Ib by supplying inert gas through the valves 3a and 3b and, if necessary, by the supply of fresh air through the fresh air systems 8a and 8b and the Frischluftzufarboweinlässe 7a and 7b, as under the Description to Figure 1 described to guarantee.
- the valves 3a and 3b are referred to in this case as area valves, since the different shelters Ia and Ib represent different areas of the monitoring.
