Definitions

  • the present invention relates to the separation of granular materials and in particular to the classification of powders or the like using dynamic air separators.
  • the separation of granular and pulverulent materials into two size fractions can be done by means of dynamic air separators.
  • the materials concerned are powders with particle sizes up to 1000 ⁇ m, such as cement, limestone or lime, ore and coal among others.
  • the rates of treated material vary from a few tons to several hundred tons per hour.
  • Dynamic separators have undergone several major evolutions allowing to classify them into 3 large families.
  • the first generation known generally 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 .
  • the document EP 0023320 also presents a device for the classification of granular materials with a lateral outlet for air charged with fine particles. This installation requires the use of additional filters and / or cyclones for the separation of fine materials.
  • the document US5,232,096 discloses an air separator with a rotating cage according to the state of the art characterized by a particular arrangement of the dispersion of the material fed into said separator. After separating the material into coarse and fine particles by means of the rotating cage, the fines and separation air are sent out of the separator to a filter or one or more cyclones where the fines will be separated from the air .
  • the present invention aims to disclose a dynamic air separator to avoid the use of external filters or cyclones, the recovery of fines being in the body of the separator itself.
  • the present invention also relates to a granulometric separation process using the separator of the invention.
  • said recovery chamber 2 may comprise fixed and / or movable baffles (4,7) for modifying the speed of the air and / or changing the direction thereof.
  • said fine material recovery chamber 2 is cylindrical or frustoconical, the cone being openable upwards or downwards.
  • said fine material recovery chamber 2 has a length which corresponds to 2 to 6 times the length of the rotating cage 1 to have a necessary and sufficient cyclone capacity.
  • said fine material recovery chamber 2 and said rotating cage 1 have the same vertical axis as the recovery chamber 2 located below and in the extension of said cage 1.
  • the deflectors 4 which are positioned in the outgoing part of the rotary cage 1 and / or in the recovery chamber 2, are driven by the rotation means of the cage 1, or by a separate device
  • the deflectors 4 which are positioned in the outgoing portion of the rotary cage 1 are fixed on said cage 1 itself.
  • the invention further specifies that the air discharge duct 3 passes through the outlet bottom of the recovery chamber 2, said duct having a diameter between 30 and 95% of the bottom diameter of the recovery chamber 2 of the fine materials.
  • a plurality of openings and / or slots is disposed in the bottom of the recovery chamber 2.
  • a plurality of ducts 8 leading to a circular airlifter conveying the material to another means of transport.
  • the separator of the invention is also characterized by the presence above the bottom of the recovery chamber 2, outside the air evacuation pipe 3, one or more conical baffles 7, cylindrical or radial (inclined or straight), to minimize turbulence around the bottom of the chamber and avoid the recovery of the material by air.
  • the invention also shows the presence of a plurality of openings in the lower part of the casing 5 of the recovery chamber 2, these openings ending in harvesting ducts of the fine material can be placed so that adequate (not shown).
  • the invention discloses the use of the device described in claim 1 for the separation and classification of inorganic material particles such as particles of cement, clinker, lime and coal.
  • the figure 1 represents the diagram of a 3rd generation separator according to prior art.
  • the figure 2 represents 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 consists of plates or spaced bars and is surrounded by louvers 14 to guide the air before entering through the inlet volute 6 in the cage 1. Des.ventelles 14 can also participate in the management of the flow air.
  • the material to be separated ends in the selection zone delimited by the outside of the cage 1 and the deflectors 4.
  • the maximum size of the particles entering the cage with the air will be determined by the speed of rotation of the cage 1 and the amount of air with which the separator will be fed.
  • the larger particles remain outside the cage and are recovered in the discharge chamber 17. These large particles leave the separator by gravity 10.
  • the charged air of the fine particles 15 leaves the cage either from above or laterally and leaves the separator by a pipe.
  • the recovery of the fine material is then done by means of cyclone (s) or filter (s) outside (s) the body of the separator.
  • 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 the figure 2 . It consists in using the vortex already created to cyclone the material to be treated 13 in an adjacent recovery chamber 2 and coaxial with the cage 1, the dust-free air 12 leaving this recovery chamber 2 through an evacuation duct. air 3 whose inlet is located inside the recovery chamber 2. The dusted air 12 is then sucked to one or more fans that return the air partially or entirely to the inlet volute of air 6 of the separator.
  • the vortex created by the rotating cage 1 can either remain free or be accelerated by fixed or movable deflectors 4 before entering said chamber. recovery 2. These deflectors 4 may also be located in the recovery chamber 2 itself.
  • the fine material 11 is centrifuged in this recovery chamber 2 and will concentrate in the outer part of the chamber where it will be harvested by means of openings in the walls (cylindrical envelope and / or bottom) of the recovery chamber 2.
  • the recovery efficiency of the fine materials 11 depends essentially on the size of the particles and their absolute density. At equal matter the important factors are the vortex intensity, ie the tangential velocity of the air throughout the recovery chamber 2, the diameter of the recovery chamber 2 and the residence time particles in said chamber.
  • the important factors will be the diameter of the recovery chamber 2, the length thereof and the tangential velocity of the air.
  • the invention therefore consists of a cage separator, provided with a fine material recovery chamber 2 which is installed coaxially in the extension of the rotary cage 1.
  • This fines recovery chamber is cylindrical or conical (frustoconical), the angle of the generatrix 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 the fine material is of the same order of magnitude as the diameter of the cage 1 as well as a length corresponding to 2 to 6 times the length of the cage 1.
  • deflectors 4 In the exit region of the 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 effected by fixing them on the cage 1 or can be set in motion by a drive independent of the cage 1. They can also be driven by the same means as the cage 1 without being fixed on said cage 1.
  • the discharge duct 3 of the air discharged with material 12 will be on its first part concentric with the recovery chamber and will preferably have a diameter of between 0.3 and 0.95 times the diameter of the bottom of the recovery chamber 2 in the plane. the entrance surface of said duct. Outlet baffles 7 may be arranged to control the air inlet direction at the entrance of the pipe.
  • the recovery of the centrifuged material is done by the application of openings on the outlet bottom and / or on the lower half of the casing 5 of the recovery chamber 2.
  • the ducts or material duct 8 are arranged opposite these openings to collect and guide the material to conventional means of transport.
  • the invention avoids the use of filters or cyclones external to the machine thus facilitating its implantation.
  • An additional advantage lies in the fact that the separation assembly is more compact, which reduces the engineering work for implantation, reduces installation costs and reduces the pressure drops in the separation circuit.
