Definitions

  • the invention relates to a method and a system for the emergency inerting of objects.
  • inerting in which an object is constantly maintained in an oxygen-reduced atmosphere
  • emergency inerting in which due to a fault message, an initially not inerted object is brought into an inertized state.
  • objects which may be subjected to emergency inerting are e.g. Bulk silos for coal dust or filter chambers in emission control systems.
  • the required inert gas is stored in a precisely defined amount either as a compressed gas or as a liquefied gas.
  • the flow rate of the inert gas is detected continuously or at predetermined time intervals, and a warning signal is given when the temperature falls below a predetermined minimum value of the gas flow.
  • a warning signal is given when the temperature falls below a predetermined minimum value of the gas flow.
  • the warning signal is advantageously a central control center from which measures may be taken to remedy a malfunction during emergency inerting.
  • the gas supply is automatically closed after a certain inertization period. This ensures that only the amount of gas necessary for the inertization is applied.
  • liquid gases such as carbon dioxide
  • gaseous gases such as nitrogen or argon
  • the gas flow rate is determined by measuring the gas pressure at the reservoir and / or in the gas supply line.
  • the gas pressure is determined continuously or at predetermined time intervals and determined on the basis of the time change of the gas pressure of the gas flow in the gas supply line.
  • the determination of the time change of the gas pressure can also be used to control the undershooting of the flow limit value.
  • the flow limit value corresponds to a specific, minimum change in the gas pressure in a given unit of time.
  • An expedient development of the aforementioned embodiments provides to close the gas supply line when a predetermined value of the gas pressure at the container. In this way, only the amount of gas required for inerting is supplied to the object to be inertized.
  • the object of the invention is also achieved by a system for the emergency inerting of an object having the features mentioned in patent claim 8.
  • the valve In the presence of a fault, which is indicated by the fault indicator, so the valve is opened in the gas supply line and the object to be inertized with inert gas flows.
  • startup signal is emitted by the signal generator to start the gas quantity detection device.
  • gas quantity detection device this means any facility that can determine the existence of sufficient gas flow for successful emergency inerting. A sufficient gas flow for a successful emergency inerting is given, in particular, if a certain minimum gas flow is constantly exceeded in the course of the emergency inerting.
  • the detection of the gas flow takes place only after a certain start-up time, which is preset by one of the gas quantity detection device pre-connected timer.
  • the plant according to the invention thus ensures a proper sequence and reliable control of the emergency inerting.
  • the gas quantity detection device is data-connected to a warning device which emits a signal when falling below a certain minimum flow value.
  • This signal can be an optical or acoustic signal, but it can also be an electrical signal that is fed to a control center. In this way, an ongoing notification of the operating personnel about any disturbances in the inerting process is provided.
  • variable area flowmeter As a particularly advantageous means for detecting the gas flow rate a variable area flowmeter is provided.
  • variable area flowmeter is operatively connected to an electrical contacting device. If a flow limit value is undershot, an electrical signal, for example to a control station, is emitted.
  • a compressed gas cylinder or a pressure tank is particularly advantageous as a storage tank.
  • gaseous storable gases are used as inert gas under pressure
  • an advantageous development of the invention provides for the gas to be stored in a reservoir connected to the gas feed line, for example a compressed gas cylinder or a pressure tank, and for the reservoir and / or in the reservoir Gas supply a pressure gauge is arranged, which is operatively connected to determine a gas flow with a time detection.
  • the duration of inertization is determined by the opening time of the valve. Therefore, in an expedient embodiment of the invention, the valve is preceded by a timer which emits a signal for closing the valve after a predetermined period of inertization.
  • the startup time and / or the duration of inertization is / are adjustable.
  • the adjustment is done mechanically or automatically, for example via a control loop.
  • a detector 6 The occurrence of an accident in region 2 is detected by a detector 6.
  • a detector 6 a smoke detector is provided in the embodiment, however, it can be used any physical or chemical parameter-detecting measuring instrument.
  • the detector 6 transmits a signal to an automatically operated valve 7 arranged in the gas supply line 4, which opens the gas supply line 4 and thus a flow connection between the liquefied gas tank 3 and the region 2 manufactures.
  • the gas quantity detection device 8 comprises a flow meter 9 arranged on the gas supply line, in the exemplary embodiment a variable area flow meter, and an evaluation unit 10 in which the value of the gas flow rate determined by the flow meter 9 is compared with a stored or predetermined flow limit value.
  • the evaluation unit 10 is an electrical contact, which is in operative connection with the float of the flow meter 9.
  • the variable area flowmeter 9 is calibrated so that in the presence of a gas flow, which is greater than the flow limit, no electrical contact is made. Only when the flow limit value is not reached is an electrical contact established and a warning signal is sent to a data center connected to the evaluation unit 10.
  • the flow meter 9 is a timer 12 is connected in parallel, which suppresses the first inevitably transmitted by the evaluation unit 10 signal and passes only after a time delay as a warning signal.
  • the gas flow rate measurement is set only after a certain period of time after opening the valve 7 in motion. This time delay is necessary because the emergency inerting system 1 is normally in the so-called standby state, in which no inert gas is delivered to the region 2. Immediately at the beginning of the inerting process in the gas supply line 4 there is therefore no or only a small gas flow and the evaluation unit 10 would thus send an incorrect warning signal to the control center 11.
  • a timer can also - not shown in the picture - be provided at the valve 7, which ensures that the gas supply line 4 after a predetermined time, which corresponds for example to a complete filling of the area 2 with inert gas, is closed again.
  • Not-inerting plant 20 for inerting a region 22 differs from the emergency inerting system 1 in particular by the fact that the inert gas is stored in the compressed, gaseous state in a gas tank 23, such as a compressed gas cylinder or a pressure tank.
  • a gas tank 23 such as a compressed gas cylinder or a pressure tank.
  • the emergency inerting system 20 has a gas quantity detection device 28.
  • the gas quantity detecting device 28 comprises a pressure measuring device 29 arranged on the gas container 23, at which the gas pressure in the gas container 23 is determined continuously or at predetermined time intervals, and an evaluation unit 30 in which the pressure change per time unit is calculated with the aid of a timer 31. From the temporal change of the gas pressure at the gas container 23, the gas flow flowing through the gas access line can be determined directly.
  • the thus determined temporal pressure change is compared in the evaluation unit 30 with a predetermined limit value of a minimum pressure change per unit time, which represents a measure of the flow limit value in a corresponding manner. If the measured pressure change falls below the predetermined value, a warning signal is transmitted to a control center 33, which is connected to the evaluation unit 30 by data. Simultaneously with the signal to the control center 33, a signal is emitted to a warning device 34, which emits an optical and / or audible warning signal.
  • the evaluation unit 30 is in the embodiment according to Fig. 2 associated with a timer 32 which suppresses the first inevitably transmitted by the evaluation unit 30 signal and transmitted only with a predetermined time delay as a warning signal.
  • the determination of the flow in the gas supply line 24 is thus set in motion only at a time delayed by this time. In this way it is reliably avoided that an incorrect error message is sent to the control center 33 when comparing the measured and the limit value in the start-up phase of the emergency inerting system 20.
  • the values of the time delay, the flow limit value, and the time duration between opening and closing of the valve 7 and 27, respectively, are determined empirically before starting up the system 1 and 20 and correspondingly at the time switch 12 or 32, respectively Evaluation unit 10 or 30 or the valve 7 or 27 set.
