Definitions

  • the invention relates to a device for the early detection of a fire in a room, which is satisfied with the conventional and inexpensive detectors that are aerosol detectors or smoke detectors of the ionization type or of the optical type, without however requiring special measurement chambers, which are also expensive, without implementing very specific substance elimination systems, such as SO2 and capable of detecting a fire of non-carbon products.
  • the detection device is characterized in that the product which forms at the start of the fire and which is detected is an aerosol or a smoke.
  • An aerosol is a colloidal system whose dispersing medium is a gas and which is called smoke when the dispersed material is a solid.
  • the detector is a conventional aerosol or smoke detector, of the ionization type or of the optical type.
  • An inlet conduit from the room opens into a cabinet and the detector is housed in the cabinet directly opposite the mouth of the inlet conduit.
  • the air stream from the room has been purified of water and dust, it can be directed to a conventional detector without disturbing its operation, especially since the latter is in a box and works in the usual conditions, as for a living space.
  • a stream of gas is sent to the coarse particle filter, against the current and intermittently, in order to unclog it periodically.
  • a suction system for example an electro-vacuum cleaner, is provided in the box where the detector is housed and ensures the circulation of an air current, possibly containing fumes, from the room to be monitored to the box in which the smoke detector.
  • the single figure of the accompanying drawing is a diagram illustrating the detection device according to the invention.
  • the condenser consists of a cold compartment 5, cooled by a refrigerant and formed by the evaporator of a conventional refrigerant system (comprising a condenser, an evaporator and a compressor and operating on freon) and of a hot compartment 6.
  • the air is cooled in compartment 5 to a temperature between 1 ° C and about 5 ° C and is brought to a temperature between 15 ° C and 40 ° C and in particular at room temperature.
  • the compartments 5 and 6 communicate by a passage 7.
  • a conduit 9 leads from the bottom of the compartment 6 to a dust filter 10 which removes particles having a size greater than 25 microns.
  • a duct 11 conducts the air, free of coarse particles, dust and moisture, onto a conventional smoke or aerosol detector 12 housed in a box 13, at the top of which an electric vacuum cleaner 14 is provided.
  • the detector is connected to an electrical signaling system, which is not shown.
  • a conduit 15 sends compressed air at 8 bar, from a source 16 of compressed air, to two nozzles 17 mounted under the filters 1, so as to be able to unclog them.
  • This unclogging compressed air circuit is operated intermittently, for example for 15 seconds every hour.
