Definitions

  • the present invention relates to a device for blowing off an explosive gas via a arranged on a roof of a building fireplace, comprising the chimney at the upper free end of a Abblasekopf is provided which consists of several out of the fireplace star-shaped outgoing manifolds, at its free end are each provided with an outlet opening.
  • the escaping gas is separated into a number of outlet openings corresponding number of gas jets, which are spatially separated from each other at least in their ignitable volume areas.
  • the gas jets can thus not ignite together, so that the pressure wave occurring due to an explosion has a smaller amplitude.
  • Object of the present invention is to provide a device of the type mentioned at the beginning, in which even in adverse wind conditions, the pressure wave load exerted in an explosion is reduced.
  • the average density is increased in the blown-out beam, whereby the beam pulse is larger.
  • the increase in average density results from the fact that air has approximately 10 times the density of hydrogen. In this way, the ignitable volumes are reduced in size and the large beam impulse does not cause any major distraction in the event of strong wind.
  • FIG. 1 shows a side view of an inventive device for blowing off an explosive gas, which consists essentially of a chimney 2 and a blow-off head 3, wherein the chimney is mounted on a roof 1.
  • the blow-off head 3 is constructed in such a way that the distributor tubes are divided into two planes. In the lower level are the distribution pipes 4 and in the upper level are the distribution pipes. 5
  • the distributor tubes of the upper level are inclined upwards by a predetermined angle, and the distributor tubes 4 and 5 are arranged alternately.
  • a jet pump 6 is located at the end of the distributor tubes.
  • the structure of the radiation pump 6 is shown schematically in FIG FIG. 3 shown.
  • the respective manifold is shown via which the hydrogen gas G is supplied.
  • the drive nozzle 8 At the end of the respective distributor tube is the drive nozzle 8.
  • the air In the mixing chamber 9 in front of it, the air is sucked in because of the negative pressure arising in the diffuser neck.
  • the gas is substantially mixed in the diffuser 11 with the sucked air to the outlet opening 7, through which it is blown.
  • ⁇ denotes the angle of inclination of the upper manifolds 5. From the FIG. 1 It can clearly be seen that due to the inclination of the upper distributor tubes 5 by a predetermined angle upwards, the ignitable volumes, which are located within the emission angles, are separated even further from one another.
