Definitions

  • the invention relates to a method for operating a fire extinguishing system for gaseous extinguishing agent, wherein an inert gas present by operating processes is used as the extinguishing agent, and an apparatus for carrying out the method.
  • inert gas As extinguishing agent, in steel mills large quantities of nitrogen are present, part of which can be used as an extinguishing agent. Inert gases are also present in chemical companies, some of which can be used as extinguishing agents.
  • inert gases present for operational processes are hazardous to persons in the volatile concentration. For this reason, employers' liability insurance associations or other authorities stipulate that inert gas must be used in fire extinguishing systems in such a way that, if triggered, technical equipment for delaying and alerting must be used.
  • the invention has for its object to use a gaseous extinguishing agent such that in the event of a fire a personal hazard is avoided and while the known rules for personal protection are met with the simplest but reliable and approved funds.
  • EP 0 574 663 A1 relates to a fire extinguishing system with a high-pressure gas as the extinguishing agent. Described is an extinguishing method for operating a gas fire extinguishing device for extinguishing areas with sensitive to extinguishing agent effects and condensate sensitive devices.
  • US 2007/0062371 A1 describes a method and apparatus for enriching the air in an aircraft cabin with oxygen as a by-product of inert gas production.
  • the object underlying the invention is achieved by diverting another part of the extinguishing agent, which is reduced by a reducing valve to a control gas pressure, from the operational process and fed to the area valve via a control system equipped with existing elements.
  • Such standard elements are available as a stock at the manufacturer of fire extinguishing systems in stock and can be used at any time, whereby the interchangeability of the controls and the service of the system is easier.
  • FIG. 1 An operating according to the inventive device is based on FIG. 1 described in more detail below.
  • an on-site gas line 1 the existing from the operational process inert gas via a shut-off valve 2 of the gas supply line 3 and a range valve 6 in an extinguishing line 4 is supplied with gas extinguishing nozzles 5, which are included in the extinguishing system 22.
  • a part of the inert gas is diverted by means of a control gas line 7 as control gas and reduced by means of a Reduzierventils 8 to a required control gas pressure and fed to a control system 9, consisting of a control unit 10 and a fire panel 11 with one or more fire detectors 12, each with a Control line 23 consists.
  • the control unit 10 is equipped with a flood timing control valve 15, a control valve 16 which is delayed by a stepping motor, a lock valve 17 and a check valve 18, all of which are arranged in series. From the fire panel 11, a control line 13 to the flood time control valve 15 and a further control line to the control valve 16 is performed. In the area to be protected is still an O 2 concentration meter 19 with a control line 20 to the fire panel 11. This opens up the possibility of reduced by a quenching with nitrogen oxygen content (O 2 ) in the extinguishing area with an O 2 concentration meter to monitor and initiate a deletion if exceeded. This can cause a resurgence of the fire be avoided. To the control gas line 7, a further control gas line 21 is indicated, which can be led to a possibly further extinguishing area.
  • O 2 nitrogen oxygen content
  • the fire detector 12 reports a fire to the fire panel 11, which controls the flood control valve 15 and the control valve 16.
  • the expiry time of the stepping motor is set such that the persons in the area to be protected can leave the room before flooding the extinguishing gas until the set time has elapsed.
  • the flood time control valve 15 is driven and the control gas flows from the line 7 to the control input of the range valve 6, which now opens to distribute the quenching gas from the gas supply line 3 via the gas extinguishing nozzles 5 to the source of fire.
  • the blocking cock 17 is provided so that in case of need, the flooding of the extinguishing gas can be prevented.

Procédé de fonctionnement d'une installation d'extinction d'incendie pour des agents d'extinction en forme de gaz, un gaz inerte présent en raison de procédés de fabrication étant utilisé comme agent d'extinction et étant acheminé à des buses d'extinction à gaz (5) à l'aide d'une commande (9) et par une valve de zone (6), qui sont à attribuer à une zone à protéger,
    caractérisé en ce que
    une partie seulement du gaz inerte présent est acheminé vers les buses d'extinction à gaz (5) et qu'une autre partie du gaz inerte est réduite à une pression de commande et est utilisée comme gaz de commande pour la valve de zone (6).
  2. Procédé selon la revendication 1, caractérisé en ce que l'autre partie du gaz inerte est acheminée, après réduction de la pression, à une unité de commande (10) d'une installation de commande (9), l'unité de commande (10) étant asservie par une centrale d'incendie (11) et ouvrant à retardement.
