Definitions

  • This invention relates to an apparatus and method for granulating a material and in particular for the atomic conversion of naturally occurring materials into naturally occurring elements as found in the periodic table.
  • U S Patent 5 402 947 describes an apparatus in which a high pressure air stream is used to create a vortex in a cyclone chamber.
  • the vortex entraps the material, holding it in a cyclonic suspension in which it is subjected to violent turbulence causing it to break up by collision and self-abrasion.
  • U S Patent 3 147 911 recognizes that the pressure of the air stream within the chamber must be sub-atmospheric and accordingly employs a suction fan or blanket to draw air through the chamber. This method necessitates that the air stream and entrained particulate material must pass through the fan subjecting it to the severe wear and tear. Accordingly this method could only be used for softer materials to a limited extent and was completely unsuitable for processing stone, coal or cement for example.
  • a further patent PCT/GB 98/00422 describes an apparatus for creating a cyclone in a stream of air passing through a conduit which is circular in cross-section.
  • centripetal forces created by the motion of the air stream pull any particulate material entrained in the air stream away from the walls of the conduit and towards its central region. If a wide range of sonic frequencies are created within the conduit, a pattern of powerful vortices are created in the air stream. Energys are released by conversion of the potential energy to kinetic energy due to the stresses created within the cyclone which causes a minute explosion. The vortices of the cyclone take the form of implosions which are capable of breaking the material up further into smaller particles.

  • this apparatus uses harmonics, tuning the frequencies generated by the vortices (or by external input) to coincide with the frequencies of the bonds in the material, thereby causing the material to implode.
  • This process has been found to have a number of difficulties, the main one being that the explosion which results in the cyclone chamber does not degrade all the material into the required size and as a result, undegraded material exits the chamber and hits the impeller. The force with which this occurs results in even the fan constructed of the materials known to man lasting no more than a few hours.

Abstract

L'invention concerne un dispositif permettant de traiter un matériau. Le dispositif comprend une chambre à cyclone; un ventilateur aspirant à rotor, qui génère une dépression tourbillonnaire à l'intérieur de la chambre; un moyen d'alimentation, qui introduit le matériau par lots dans la chambre; et un moyen permettant de rassembler le matériau traité. Le rotor et/ou l'orifice d'entrée de la chambre sont conçus pour abaisser la température de l'eau dans la chambre jusqu'à une température proche du zéro absolu. Dans ces conditions de température et de vide, le matériau à traiter est soumis à des forces qui provoquent la dissociation des liaisons à l'intérieur dudit matériau. La chambre est conçue pour contenir les explosions ou implosions susceptibles de se produire et pour assurer que la recombinaison de l'hydrogène et de l'oxygène forment de l'eau avant l'orifice de sortie.
