Definitions

  • Swiss Patent No. 588.663 describes and represents a ventilation hood comprising a secondary chamber disposed downstream of the primary chamber overhanging the stove, this secondary chamber containing a filter and at least one set of fixed cleaning nozzles arranged to spray water on the filter and on at least part of the walls of the secondary chamber.
  • hood means are arranged at the lower part of the secondary chamber for collecting and evacuating the cleaning water coming from the nozzles.
  • the present invention relates to an installation comprising a ventilation hood of this type.
  • the installation according to the invention is characterized in that it comprises a heat exchanger disposed in the secondary chamber, towards its outlet giving into a gas evacuation channel, and in the path of the water sprayed by a au less sets of cleaning nozzles.
  • This exchanger acts both as a heat recovery unit and as an additional filter element in the hood. Its cleaning is done automatically at the same while cleaning the filter under the effect of water sprayed from the nozzles.
  • 3 is the ventilation hood, above the furnace 2 and fixed to the wall 1.
  • This hood has a primary chamber 4 having a wall 5, 6, of the general shape of a dihedral open at the bottom and s 'pressing by one of its edges 7 against the wall 1.
  • the hood further comprises a secondary chamber 8 disposed in the front part of the hood and communicating with the primary chamber by a channel 9 opening into the lower region of the chamber 8.
  • This channel is formed between the edge 10 of the part 6 of the dihedral and an oblique fixed wall 11 integral with the lower part of the hood.
  • the air entering the secondary chamber through the opening 9 is forced to pass through a filter constituted by a grid 12, before reaching the chimney or outlet channel 13.
  • This grid is of a known type having means for adjusting the width of the interstices between its bars.
  • pipes 14, 15, and 16 each provided with nozzles for spraying water.
  • the piping 14 comprises a set of nozzles 17, the piping 15 two sets of nozzles 18, 19, spraying in two different directions, and the piping 16 comprises a set of nozzles 20.
  • the installation shown differs from what the aforementioned patent shows by the fact that a heat exchanger heat 21 is disposed in the secondary chamber 8, towards its outlet giving into the gas discharge channel 13.
  • This heat exchanger can be of known type and is used to ensure heat recovery, for example to provide hot water in the kitchen or for any other use.
  • the exchanger 21 is disposed in an opening in a wall 22 closing in a way the outlet of the secondary chamber so that the gases are forced to pass through the exchanger to reach the channel 13.
  • the set of nozzles 17 is provided for squirt on one of the faces of the heat exchanger 21, while the game 18 is arranged to squirt on the opposite face of this exchanger.
  • the set of nozzles 19 spurts on one side of the grid 12 and the nozzle 20 on the opposite side of the grid 12.
  • a means for collecting and discharging by a conduit 24 the water laden with residues thus removed from the grid 12 and of the exchanger 21 under the effect of the spraying by the nozzles.
  • the exchanger 21 very significantly increases the filtration efficiency thanks to the pressure drops that it causes.
  • the position of this exchanger means that it benefits from the periodic rinsing of the hood and that it thus retains its full effectiveness over time.
