Definitions

  • the chamber may comprise first and second opposite wall portions extending between the first and second ends.
  • the chamber may be orientated with the second end, at which the gas outlet is located, positioned above the first end, at which the gas inlet is located, and the wall portions extending generally vertically.
  • the gas flows generally vertically upwards through the chamber from the gas inlet to the gas outlet and the particles may flow generally radially with respect to the wall portions.
  • the chamber may be orientated with the second end, at which the gas outlet is located, positioned to the side of the first end, at which the gas inlet is located, and the wall portions extending generally horizontally.
  • the gas flows generally horizontally through the chamber from the gas inlet to the gas outlet and the particles may flow generally vertically between opposite wall portions.
  • the gas flow arrangement may comprise a gas feeder for feeding the gas to the chamber through the gas inlet.
  • gas and particle mass flow rates may be controlled, the selection of which being based on the application for which the gas-particle processor is being used.
  • the process may be gas and particle phase controlled because of the reaction, with catalyst particle flow controlled to provide the required chemical conversion.
  • the processor is used as a cooling tower for example (with particles in the form of liquid droplets)
  • operation of the processor may also be gas phase controlled.
  • the liquid particles are injected at a mass flow rate that will provide the surface area for the cooling tower process.
  • the processor 2 is operated such that the gas flows through the chamber 3 at a streamline (first) velocity which is generally linear in the horizontal direction.
  • flow straighteners such as baffles may be provided near the gas inlet 25. It is noted that during operation the gas velocity will vary across the chamber due to the heat and/or mass transfer occurring within the chamber.
  • the particles Upon entering the chamber, the particles travel along a spiral flowpath out towards the inner surface of the chamber carried by a spiralling gas flow which is under the influence of a gas rotator (described below) where they exit the chamber through the particle outlets 108A-C.
  • a gas rotator described below
  • Each particle outlet 108A-C is located upstream of its respective inlet 104A-C as the particles are carried upwards somewhat by the gas (against gravity) as the particles move through the chamber.
  • the gas moves in a general direction which is vertical through the chamber
  • a stream of alumina particles of 200 pm in diameter, a mass flowrate of 244 tonnes/hr and a temperature of 200 °C is introduced into the chamber from particle feeder 5A.
  • heat exchange occurs between the particle stream and the gas stream at stage 18A. This results in cooling of the alumina stream to 169 °C under ideal conditions. Recycling of this particle stream occurs as it exits through particle outlet 8A and is fed to particle inlet 4B via conduit 12A. For the purposes of this calculation, no or little heat exchange is assumed for the flow in any connecting conduits.
  • the particle stream re- enters processor 2 at stage 18B.
