Definitions

  • the invention relates to a system for extinguishing and / or inerting according to the preamble of the first claim.
  • Prior art for liquid extinguishing agents such as water and aqueous solutions are fire extinguishing systems in which this extinguishing liquid is stored in extinguishing agent containers and is conveyed by a suitable conveyor such as a pump through pipes to the extinguishing nozzles and discharged through this to the fire or in a room to be inerted becomes.
  • Synthetic extinguishing agents are stored in liquid containers in pressure vessels. Since in most cases the internal vapor pressure of the extinguishing agent is not sufficient to transport the extinguishing agent in the prescribed time through a pipeline and to ensure the required minimum nozzle pressure, in most cases pressurization with a gas, eg. Nitrogen. At the nozzles evaporates the liquid extinguishing agent, creating a gaseous Lösch capablees extinguishing agent-air mixture is formed.
  • Synthetic liquid extinguishing or inerting agents are extinguishing agents such as halogenated hydrocarbons, fluorocarbons fluoroketones or synthetic fluids with comparable properties.
  • the document US 2002/027143 A1 discloses a liquefied gas quench plant in a quench tank and special sputter nozzles.
  • the extinguishing agent is hereby stored in the quench tank at a pressure of up to 100 psig, based on room temperature of 25 ° C.
  • the extinguishing agent is forced through the piping network by a propellant gas under high pressure, which is stored in a separate container and introduced into the extinguishing agent container. There is no control of the application of the amount of extinguishing agent via a fire alarm and / or control center or concentration sensors.
  • EP 0557275 B1 describes a fire extinguishing procedure that uses different synthetic extinguishing agents to prevent fire in a confined space.
  • DE 100 51 662 A1 describes a method for extinguishing a fire which has broken out within a closed space by means of nitrogen, compressed gas cylinders serving to store and store this gas.
  • DE 10 2006 048 015 A1 describes a fire extinguishing system for a housing in which an extinguishing agent container with chemical liquids is arranged as extinguishing agent, wherein as extinguishing NOVEC 1230, HFC 227a, HFC 125, fat Ex, argon or N 2 are arranged, wherein a propellant gas from a charging cartridge discharges the extinguishing agent ,
  • the extinguishing agent container is in any case a pressure vessel.
  • DE 696 01 861 T2 describes a fire extinguishing agent which comprises at least one partially fluorinated compound and a process for extinguishing, combating or preventing fires using such compositions, said fire extinguishing agent also being called C 4 F 9 OCH 3 .
  • the vapor pressure of said synthetic liquid extinguishing agent at 21 ° C may be between 50 and 0.1 bar.
  • synthetic liquid extinguishing media with too low a vapor pressure with a gas e.g. Nitrogen permanent or superimposed upon release with pressure. Therefore, it is assumed in the storage, transport, delivery and spreading over extinguishing nozzles in plants of this type that these extinguishing agents are gases for the approved and costly pressure vessels, extinguishing nozzles, valves, pipe networks, filling and monitoring equipment As well as special components are required, making the creation and operation of fire extinguishing systems with synthetic liquid extinguishing agent is extremely expensive.
  • the solution according to the invention provides a system for extinguishing and inerting with a synthetic liquid, which consists of the extinguishing agent container, the conveyor for the extinguishing agent, the pipeline to the nozzles and fittings, with an event detector is arranged, detects the fire signals and to a fire detector and / or control center forwards.
  • a synthetic liquid extinguishing agent is stored in a preferably closed extinguishing agent tank at a low vapor pressure of ⁇ 3 bar based on 21 ° C.
  • a conveyor promotes the synthetic extinguishing agent via a pipe to nozzles over which it is evaporated until a certain concentration is achieved in the space to be monitored. This concentration is measured and regulated by a concentration sensor and can be calculated in advance by appropriate calculations and design of the system.
  • the synthetic extinguishing agent is a non-flammable, non-flammable, electrically non-conductive liquid extinguishing agent, advantageously having a vapor pressure at 25 ° of 25 to 28 KPa, preferably 26.8 KPa.
  • the synthetic liquid extinguishing agent at 21 ° C has a density of 1,400 to 1,800 kg / m 3 .
  • liquid extinguishing agents are FK-5-1-12,], 1,1,1,2,2,4,5,5,5-NONAFLUORO-4- (TRIFLUOROMETHYL) -3-PENTANONE (C4F9OCH3) or other synthetic fluids like fluoroketones with comparable properties.
  • the extinguishing agent container is a closed extinguishing agent container, which may be made of plastic, metal or other suitable materials. On it openings for receiving or for connection of level monitoring, a drying cartridge with valve, filling openings, removal openings are arranged.
  • the extinguishing agent containers are only designed for an operating pressure of up to 3 bar. This allows cost-effective solutions and requires less effort for technical approvals.
  • a level monitoring such as a mechanical float or electrical level monitoring such as ultrasound. From the level monitoring, a signal can be given via electrical lines or via radio to a fire alarm and / or control center.
  • a drying cartridge with valve can be arranged in the extinguishing agent container.
  • This can be a single or reusable dehumidification cartridge for dehumidifying the air flowing in during extinguishing agent extraction.
  • An integrated valve then optionally diverts a resulting overpressure into the environment in the container. This overpressure should be at 2 bar. The response value depends on the extinguishing agent used.
  • a dehumidifier such as a dehumidifier.
  • a drying cartridge e.g. a pressure relief device for overpressure and underpressure, e.g. a valve or a combination of these devices.
  • the systems are equipped with a pressure relief valve to compensate for the volume reduction caused by the discharge of the extinguishing agent. As a rule, this air is sucked from the outside.
  • a gas e.g. Nitrogen
  • a pump which is suitable for conveying or for increasing the pressure of liquid media.
  • the drive can be done electrically or pneumatically.
  • the conduits used to convey the synthetic liquid extinguishing agent can be made of metal, plastic or other suitable materials.
  • the pipelines are designed for the usual pressure of 16 bar, as they are common for conventional water systems.
  • the nozzles for dispensing the synthetic liquid extinguishing agent are nozzles used for the fine atomization of water, e.g. Full or hollow cone nozzles.
  • extinguishing agent container may also be advantageous to arrange several extinguishing agent container.
  • one or more concentration sensors are arranged, which are designed as oxygen or extinguishing agent sensors, the detected value of which enables a direct determination of the extinguishing agent concentration in the relevant room.
  • This value serves as a controlled variable for the quantity of extinguishing agent to be delivered.
  • it is forwarded to the fire alarm and / or control center, which controls the discharge of the amount of extinguishing agent via the conveyor after a predetermined value or limit.
  • event messages are arranged. These may advantageously be automatic event reporting. These detect deviations from the normal state of the environment such as e.g. Fire characteristics or signals that indicate thermal decomposition and whose cause may be a fire or a fire or smoldering fire or physical characteristics of any other incident that may cause a fire. Furthermore, the signals detected by the event detector are called fire signals.
  • the smoke detectors CO detectors, fire gas detectors, flame detectors, radiation detectors, Rauchansaugsysteme and manual triggering devices such as manual call points.
  • the fire alarm and control unit carries out all the monitoring, control, regulation, alarms, switching off and on and forwarding of operating states required for the function of the system.
  • the fire alarm and control center can be connected both to the conveyor and to the level monitoring device. Furthermore, the fire alarm and / or control center detects and processes the signals of the event report.
