Definitions

  • the present invention relates to an extinguishing device such as that which is connected in particular to containers and pipes in order to be able to introduce an extinguishing agent into the container or the pipe in the event of a critical situation.
  • Such extinguishing devices are used in industrial plants, in particular in plants for process engineering, for explosion suppression and explosion decoupling.
  • Extinguishing devices use sensors to detect sparks, flames or a rise in pressure and immediately trigger the opening of the connected extinguishing device.
  • the extinguishing device distributes an extinguishing agent, a highly effective extinguishing powder, at lightning speed, and suffocates the explosion as it develops.
  • an extinguishing device is used to decouple the explosion, an explosion occurs in a first of several interconnected areas.
  • This first area is preferably equipped with a pressure relief device.
  • the extinguishing device can prevent the explosion from jumping over from the first area into connected areas.
  • the remaining areas are decoupled from the first area by means of the extinguishing device.
  • the extinguishing agent is introduced into the connections by means of the extinguishing device.
  • the extinguishing agent extinguishes an approaching flame front.
  • the remaining areas are thereby decoupled from the first area.
  • the explosion does not spread from the first area to the other areas.
  • the pressure wave can be derived from the first area via the pressure relief device become. Under certain circumstances, the extinguishing agent introduced may be sufficient to completely extinguish the fire in the first area.
  • This known extinguishing device has a connecting means for connecting the extinguishing device to a wall of the area to be protected.
  • the area to be protected can be a container or a pipe, for example.
  • the wall to which the connecting means of the extinguishing device can be connected has an extinguishing agent inlet opening through which the extinguishing agent can be introduced from the extinguishing device into the area to be protected in order to act there.
  • the well-known extinguishing device has proven itself in the past as a reliable means of suppressing and decoupling explosions. Over time, however, it has been recognized that there is a need for improvement, e.g. so that the extinguishing device can preferably be installed more easily.
  • Easier assembly could be achieved, for example, by reducing the number of extinguishing agent containers that are used to protect a technical system. This can also be achieved in that the extinguishing device can be handled more easily by a fitter during assembly.
  • a group of inventions presented below makes its contribution to reducing the number of extinguishing agent containers and improving handling during assembly.
  • the number of extinguishing agent containers required to protect a technical system can be reduced by the fact that the extinguishing agent of an extinguishing device can be used more effectively, i.e. a larger area can be reached with the same amount of extinguishing agent.
  • the handling during the assembly of the extinguishing device can be improved according to the invention in that the weight of the extinguishing device is reduced. According to the invention, this can be achieved in that less extinguishing agent is filled into the extinguishing agent container for suppressing or decoupling explosions and this smaller amount of extinguishing agent is used more efficiently for suppressing or decoupling explosions.
  • the weight of the extinguishing device can also be reduced by using handles and stands that are detachably connected to the extinguishing agent container.
  • the handling during the assembly of the extinguishing device can also be improved according to the invention in that the fastening is possible with fewer hands.
  • a more efficient use of extinguishing devices can be achieved by a device according to the invention for forming a jet of extinguishing agent.
  • the number of extinguishing devices required for securing or decoupling an area can be reduced.
  • a more efficient use of the extinguishing agent and thus a reduction in the weight of the empty as well as the filled extinguishing agent container can also be achieved by a device for forming an extinguishing agent jet according to claim 1.
  • the amount had to be so large that a minimum amount of extinguishing agent was achieved in each of the areas in the container or pipeline into which the extinguishing agent had to be introduced to suppress or decouple the explosion, regardless of the fact that in other areas too much a lot of the extinguishing agent arrives.
  • a device according to the invention for shaping a jet of extinguishing agent has a jet shaper, the jet shaper having at least one base body with several first through recesses for the quenching agent emerging from the extinguishing device.
  • the jet shaper By means of the first continuous recesses in the base body, it is possible to shape the jet of extinguishing agent, for example in order to set a dispersion, a twist, a speed or the like.

  • This cover it is possible to protect the jet shaper from a medium located in the container or pipe to be protected.
  • the cover can be a sheet metal or a film, which advantageously has at least one predetermined breaking point. As soon as the extinguishing agent emerges from the extinguishing agent container and passes through the jet shaper, the cover can be destroyed in order to prevent unhindered entry of the extinguishing agent into the container or the pipe to be protected.
