Definitions

  • the present invention relates to the dilution in air of a gas or a gaseous mixture, before its rejection to the atmosphere.
  • the present invention aims to propose for this purpose a method which is easy to implement, even when the quantities of gas to be discharged are significant. It also aims to propose a method, the implementation of which requires a device which is easy to produce and maintain during use.
  • the subject of the invention is a method of diluting a gas or a gaseous mixture in air, before it is released into the atmosphere, using a device comprising a profiled body. forming a venturi, open to the atmosphere at its two ends and at the upstream end of which said gas or gas mixture is injected under pressure, process characterized in that said gas or gas mixture is injected into said body in the form of a ply with annular cross section using at least one set of injection tubes, the circular orifices of which are arranged in a crown at the upstream part of said venturi body.
  • said gas or gaseous mixture will be injected into said body using a plurality of sets of injection tubes arranged in a crown, said sets being offset from upstream to downstream and such as the successive layers of said gas or gas mixture produced by said means have increasing cross sections from upstream to downstream.
  • the sets of successive injection tubes will preferably open into the upstream part of a tubular structure forming a venturi and the injection means arranged downstream of this structure will be located substantially in the extension of the downstream part thereof.
  • the injection pressures may be different at each injector and even be zero, in order to obtain the optimum dilution effect during each injection.
  • additional air inlets can be provided laterally in the downstream part of said venturi body, in order to increase the gas dilution effect.
  • the dilution in the air before rejection to the atmosphere must be such that one is outside the flammability limits for its constituents, in particular for hydrogen and methane, which is most commonly found in residual gases released to the atmosphere.
  • the single figure of the appended drawing is a partial section of a device comprising two sets of injectors with circular orifices arranged in a ring, offset from upstream to downstream, usable in the implementation of the method according to the invention.
  • the device shown in this figure comprises a body 20, forming a venturi, open to the atmosphere at its two ends, into which the gas to be diluted is injected by a plurality of tubes 21 carried by a plate 22.
  • the tubes 21 are supplied by a manifold 23 and their discharge orifices 24 are arranged in the upstream part of the body 20 so as to form a crown there.
  • the tubes 25 arranged upstream and carried by the plate 26 are supplied with gas by the manifold 27 and preferably open at the downstream end, open to the atmosphere, of a venturi 28, while the downstream tubes 21 are arranged substantially in the extension of the downstream part of the venturi 27.
  • the side walls of the downstream part of this venturi may advantageously be pierced with additional air inlets 29.
  • the invention therefore provides a simple and easy to implement method for diluting in the ambient air a gas or a mixture of gases before its rejection to the atmosphere.

1. Verfahren zum Verdünnen eines Gases oder eines Gasgemisches mit Luft vor dessen Ausstoß in die Atmosphäre mit Hilfe einer Vorrichtung, die aus einem Stahlkörper (20) der ein Venturirohr bildet, besteht, welches an seinen beiden Enden gegen die Atmosphäre offen ist, und an dessen stromaufwärts gelegenen Ende das Gas oder das Gasgemisch unter Druck eingeblasen wird, dadurch gekennzeichnet, daß das Gas oder Gasgemisch in den Körper, mit einer im Querschnitt kreisförmigen Mantelfläche, mit Hilfe von zumindest einer Einheit von Injektionsrohren (21), deren runde Öffnungen (24) kronenförmig an dem stromaufwärts gelegenen Ende des Venturirohres (20) angeordnet sind, eingeblasen wird.
2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß das Gas oder das Gasgemisch in den Körper durch eine Mehrzahl von kronenförmig angeordneten Einheiten von Injektionsrohren (21, 25) eingeblasen wird, wobei diese Einheiten von stromaufwärts nach stromabwärts versetzt angeordnet sind, und daß die durch diese Einrichtungen gebildeten aufeinanderfolgenden Mantelflächen des Gases oder Gasgemisches von stromaufwärts nach stromabwärts einander kreuzende Querschnitte aufweisen.
3. Verfahren nach Anspruch 2, dadurch gekennzeichnet, daß die aufeinanderfolgenden Einheiten von Injektionsrohren (25) in den stromaufwärts gelegenen Teil eines röhrenförmigen Bauteiles (28) der die Form eines Venturirohres aufweist, münden, und daß die Leitungen (21) der Injektionsrohre, die stromabwärts von diesem röhrenförmigen Bauteil (28) angeordnet sind, ungefähr in der Verlängerung des stromabwärts gelegenen Endes derselben liegen.
