Definitions

  • the present invention relates to the separation of granular materials and in particular to the classification of powders or the like with the aid of dynamic air separators.
  • the separation of granular materials and pulvurelents in two granulometric fractions can be do by means of dynamic air separators.
  • the concerned materials are powders with sizes of particles up to 1000 ⁇ m, such as cement, limestone or lime, ore and coal between other.
  • the flows of treated material vary from a few tons to several hundred tons per hour.
  • Dynamic separators have known several major evolutions allowing to classify them in 3 large families.
  • the first generation known usually under the names “turbo”, “heyd” or “Whirlwind” has been improved by the second generation " type wedag ".
  • the 3rd generation is the most effective from the viewpoint of the separation efficiency.
  • the operating principle of the separators (O'Sepa, Sturtevant SD, 7) is described in the documents USP 4,551,241 and EP 0023320.
  • US 4,551,241 discloses a particle separator with a lateral cyclone in which particles are returned to be cycloned. The surplus being returned to the rotating cage of separator. The entire installation turns out relatively bulky and quite complex design.
  • EP 0023320 also presents a device for the classification of granular materials with a side outlet for air loaded in fines particles. This installation requires the use of additional filters and / or cyclones for separation fine materials.
  • the present invention aims to disclose a dynamic air separator to avoid the use of external filters or cyclones, the recovery of fines occurring in the body of separator itself.
  • the present invention also relates to a granulometric separation process using the separator of the invention.
  • said recovery chamber 2 may have baffles fixed and / or mobile (4.7) to change the air speed and / or change the direction of it.
  • said recovery chamber 2 of the fine materials is cylindrical or frustoconical, the cone can be opened upwards or downwards.
  • said chamber of recovery 2 of the fine materials has a length that corresponds to 2 to 6 times the length of the rotating cage 1 to have a necessary cyclone capacity and sufficient.
  • said recovery chamber 2 of the fine materials and said cage rotating 1 have the same vertical axis as the chamber recovery 2 located below and in the extension of said cage 1.
  • the deflectors 4 which are positioned in the outgoing part of the rotating cage 1 and / or in the recovery chamber 2, are trained by the means of rotation of the cage 1, or by a separate device
  • the deflectors 4 which are positioned in the outgoing part of the rotating cage 1 are attached to said cage 1 itself.
  • the invention further specifies that the conduit air outlet 3 crosses the bottom outlet of the recovery chamber 2, said duct having a diameter between 30 and 95% of the diameter of the bottom of the chamber recovery 2 fine materials.
  • a plurality of openings and / or slots is disposed in the bottom of the chamber of recovery 2.
  • conduits 8 leading to a means of transporting the material.
  • ducts 8 leading to a circular hovercraft transporting the material to another means of transport.
  • the separator of the invention is characterized also by the presence above the bottom of the room 2, outside the pipe of evacuations of the air 3, of one or more deflectors 7 tapered, cylindrical or radial (inclined or straight), so to minimize the turbulence around the bottom of the room and avoid the recovery of the material by the air.
  • the invention also shows the presence of a plurality of openings in the part lower envelope 5 of the recovery chamber 2, these openings ending in harvesting ducts fine material that can be properly placed (not shown)
  • the invention discloses the use of device described in claim 1 for the separation and classification of particles of matter mineral such as cement particles, clinker, lime and coal.
  • FIG. 1 shows the diagram of a 3rd generation separator according to prior art.
  • FIG. 2 shows the schematic diagram of the separator of the invention.
  • the heart of the separator consists of a squirrel cage 1 rotating around a vertical axis.
  • This cage is consists of spaced plates or bars and is surrounded 14 vents to guide the air before entering by the inlet volute 6 in the cage 1. Les ventelles 14 can also participate in the management of the airflow.
  • the material to be separated ends up in the zone of selection delimited by the outside of cage 1 and the deflectors 4.
  • the maximum size of incoming particles in the cage with the air will be determined by the speed of rotation of cage 1 and the amount of air with which the separator will be fed.
  • the larger particles remain at the outside of the cage and are recovered in the room 17. These large particles come out of the separator by gravity 10.
  • the air charged with fine particles 15 leaves of the cage either from above or sideways and leaves the separator by a pipe.
  • the recovery of the material fine is then done by means of cyclone (s) or filter (s) outside (s) to the separator body.
  • the air enters the cage 1 with a tangential speed of the same order of magnitude as the circumferential speed of the cage.
  • the tangential component of the velocity increases naturally with the penetration of the air inside the cage 1 (vortex effect).
  • the principle of the invention is schematized in Figure 2. This one consists in using the vortex already created to cyclone the material to be treated 13 in a recovery chamber 2 adjacent and coaxial to the cage 1, the dusted air 12 leaving this room recovery 2 by an exhaust duct 3 of which the entrance is located inside the room of recovery 2. The dusted air 12 is then sucked to one or more fans that return the air in part or in total towards the air inlet volute 6 of the separator.
  • the vortex created by the rotating cage 1 can either remain free or be accelerated by deflectors fixed or movable 4 before entering that chamber of recovery 2. These deflectors 4 can also be located in the recovery chamber 2 itself.
  • the fine material 11 is centrifuged in this recovery chamber 2 and will focus in the outer part of the room where it will be harvested means of openings in the walls (cylindrical envelope and / or bottom) of the recovery chamber 2.
  • Material recovery efficiency fine 11 depends essentially on the particle size and their absolute density. With equal matter the factors important are the intensity of the vortex, that is the tangential velocity of air throughout the chamber of recovery 2, the diameter of the recovery chamber 2 and the residence time of the particles in said chamber.
  • the important factors will be the diameter of the recovery chamber 2, the length of it and the tangential velocity of the air. More tangential component of the air is important and the longer the room, the better the performance of recovery.
  • the invention therefore consists of a separator to cage, equipped with a recovery chamber of fine materials 2 which is installed coaxially in the extension of the rotating cage 1.
  • This fine recovery chamber is cylindrical or conical (frustoconical), the angle of the generator of the cone with the axis of revolution of the cone being preferably less than 30 °, the inlet diameter of the recovery chamber 2 of fine materials is the same order of magnitude than the diameter of the cage 1 and a length corresponding to 2 to 6 times the length of the cage 1.
  • cage 1 and / or in the recovery chamber 2 can be installed fixed or movable deflectors 4 for influencing the direction of the air nets.
  • the possible rotation of these deflectors 4 can be made by fixing them on the cage 1 or then be set in motion by a independent drive of the cage 1. They can also be trained by the same means as cage 1 without being fixed on said cage 1.
  • the exhaust duct 3 of the air discharged from matter 12 will be on its first part concentric to the recovery chamber and will preferably have a diameter between 0.3 and 0.95 times the diameter of the bottom of the recovery chamber 2 in the plane of the surface input of said conduit.
  • Outlet baffles 7 can be arranged to control the direction air inlet at the entrance of the pipe.
  • the recovery of the centrifuged material is by the application of openings on the output background and / or on the lower half of the envelope 5 of the chamber of recovery 2. Sheaths or ducts of material 8 are arranged in front of these openings to collect and guide the material towards conventional means of transport.
  • the invention avoids the use of filters or cyclones external to the machine facilitating by consequently its implantation.
  • An added benefit lies in the fact that the separation set is no longer compact, which decreases the engineering work for implementation, reduces installation costs and decreases the pressure drops in the separation circuit.
