Definitions

  • the invention relates to a method for drying particulate material such as hydrocarbonous particulate material, for example oil shale, as defined in the preamble of independent claim 1.
  • the invention also relates to an arrangement for drying particulate material such as hydrocarbonous particulate material, for example oil shale, as defined in the preamble of independent claim 13.
  • particulate material such as hydrocarbonous particulate material, for example oil shale
  • the invention relates also to the use of the method or to the use of the arrangement as defined in claim 25.
  • the invention relates especially to drying of hydrocarbonous particulate material in the form of shale oil.
  • the method and arrangement of the invention can however also be utilized for drying other kind of particulate matter.
  • particulate material falls from the drying section of the venturi dryer through the venturi throat into the gas feeding section of the venturi dryer, where the temperature is relative high, for example 400 to 500°C.
  • This high temperature causes the temperature of the particulate material present in the gas feeding section of the venturi dryer to raise i.e. to causing the hydrocarbonous particulate material to overheat and consequently to cause hydrocarbon and/or CO emissions.
  • the object of the invention is to provide a method and an arrangement for drying particulate material such as hydrocarbonous particulate material, for example oil shale, that lowers the risk to cause undesired emissions.
  • particulate material such as hydrocarbonous particulate material, for example oil shale
  • the method for drying particulate material such as hydrocarbonous particulate material, for example oil shale, of the invention is characterized by the definitions of independent claim 1.
  • the invention relates also to the use of the method as defined in any of the claims 1 to 12 or the arrangement as defined in any of the claims 13 to 24 for drying particulate material in the form of shale oil as defined in claim 25.
  • the invention is based on the idea of feeding particulate material at several points into the drying section of the venturi dryer. This leads to a more even distribution of particulate material in the drying section of the venturi dryer, which in turn lowers the risk that particulate material falls from the drying section of the venturi dryer through the venturi throat into the gas feeding section of the venturi dryer.
  • the screw feeders are connected to the drying section of the venturi dryer at feeding openings so that the central axis of the venturi dryer is uncut by imaginary extension of the rotation axis of the screw feeders.
  • the screw feeders are connected to the drying section of the venturi dryer at feeding openings so that the feeding openings at which the screw feeders opens into the drying section of the venturi dryer are provided symmetrically with respect to the central axis of the venturi dryer. This leads to an even distribution of particulate material in the drying section of the venturi dryer, because the feeding openings are situated as far as possible from each other.
