Definitions

  • the invention relates to a process for depositing fluids in a solids flow of a spouted bed apparatus and an associated apparatus.
  • a spouted bed apparatus for producing granulates for which a fluid is introduced into the solids flow of the spouted bed granulator.
  • the spouted bed apparatus has a round cross section, whose lower part is formed with a conical taper.
  • a gas channel, where a nozzle for injecting the fluid is arranged, opens into the central conical part of the spouted bed granulator.
  • An appropriate gas is fed through the gas channel for maintaining the spouted bed.
  • the centrally fed gas entrains the fluid introduced by the nozzles and a portion of the material located in the spouted bed granulator, wherein a stream channel is produced in which the material particles are wetted with the fluid.
  • the sprayed material is fed back to the stream channel over the conical base, so that particle circulation is generated. After achieving an adequate granulate size, the granulates are discharged from the spouted bed granulator.
  • a disadvantage for this type of spouted bed granulator is that the supply of gas for generating the spouted bed and the introduced fluid is supplied at a common location in the lower part of the spouted bed granulator.
  • a uniform wetting of all material particles to be treated with fluid is hard or impossible to realize. Some material particles are sprayed with too much and others with too little fluid, so that an end product with equal grain size and equal material structure cannot be realized.
  • these systems are only suitable for granulation at low material throughputs. For greater throughputs, problems appear in terms of generating and maintaining the spouted bed.
  • Previously known from the publication DE 100 04 939 C1 is a spouted bed apparatus for fluidization and thermal treatment of essentially arbitrarily shaped materials with different particle dimensions as well as particle masses.
  • the spouted bed apparatus for batch or continuous process control consists of a inlet air chamber arranged in the lower region of the spouted bed apparatus, into which the fluidizing means, such as, especially air, is supplied.
  • the fluidizing means is fed to the fluidization region of the spouted bed apparatus by means of a controllable gas flow device arranged between the inlet air chamber and the fluidization region.
  • the fluidization region is formed by the gas flow device arranged in the lower region, as well as by a stream inlet wall, a stream return flow wall lying opposite the stream inlet wall, and also the side walls.
  • the stream inlet wall and the stream return flow wall are inclined relative to the vertical, so that they form a cone. Therefore, an expanded cross section of the spouted bed apparatus is formed above the stream inlet wall and the stream return flow wall. This expanded section is used as an expansion region for the fluidizing means and is provided with an outlet for the exhaust air.
  • the spouted bed apparatus can be one-sided or two-sided, i.e., it can be formed with a double cone.
  • the object of the invention is to create for a spouted bed apparatus a process and an associated apparatus with which a fluid can be selectively and adjustably deposited on the material in the spouted bed for producing coated granulates, for wetting material particles, and for granulation and agglomeration of different materials for a wide range of industrial branches, so that an end product is produced with approximately equal grain size and equal material properties even for large material throughputs.
  • Another advantage of the solution according to the invention is that with the proposed process and apparatus, the material to be treated can be exposed to various technologies, such as granulation, agglomeration, wetting, and coating.

  • the dedusting system 19 is provided with a known filter cleaning device 18 , which feeds the separated dust into the reaction space 26 of the spouted bed apparatus.
  • FIG. 1 shows a preferred variant of the formation of reaction space 26 , for which the lower region of the reaction space 26 is limited in the axial direction by two inclined stream return flow walls 2 , which are each associated with an inclined stream inlet wall 3 under the formation of two axial gaps 1 . These return flow walls are connected together in the top region.
  • the lower region of the reaction space 26 can also be formed by only one inclined stream return flow wall 2 and an opposing inclined stream inlet wall 3 under the formation of an axial gap 1 running through the reaction space 26 for supplying inlet air 10 .
  • Controllable valve devices for setting the amount and the rate of the air flow 12 fed to the reaction space 26 are arranged in the gap 1 .
  • the gap 1 is formed such that the air flow 12 of the inlet air 10 is fed against the lower region of the stream inlet wall 3 .

  • Several nozzles 6 and/or 7 and/or 17 arranged one next to the other in the axial direction of the reaction space 26 open into the reaction space 26 of the spouted bed apparatus.
  • an axial separating plate 16 whose lower edge is at a distance to the stream return flow wall 2 , is arranged in the lower region of the reaction space 26 between the stream return flow wall 2 and the housing wall 3 .
  • FIG. 3 a spouted bed apparatus is shown without an integrated dedusting system 19 .
  • the dust-bearing exhaust air 20 is discharged as exhaust air 11 from the spouted bed apparatus and is dedusted in a downstream, separate dedusting system that is not shown.
  • FIG. 4 a multi-stage spouted bed apparatus is shown, which is formed from several reaction spaces 26 arranged one next to the other.
  • two adjacent reaction spaces 26 are connected to each other over a common overflow port, which is formed for the first reaction space as a solids discharge 5 and for the second reaction space as a solids inlet 13 .
  • the lower region of the inlet air chamber 8 can be divided into several segments through the arrangement of separating walls 25 , which enclose one or more reaction spaces 26 .

  • the process according to the invention for introducing fluid into a solids flow of a spouted bed apparatus for producing coated granulates, for wetting material particles, and for the granulation and agglomeration of different materials for a wide range of industrial branches generates at least one circular solids flow 15 in the axial direction of the reaction space 26 , in which a fluid is injected.
  • the solids flow 15 is formed with an upwards flow 22 with a high flow rate, with a cross flow 23 with a lower flow rate, and with a downwards flow 24 , which has a lower flow rate than the cross flow 23 , by supplying inlet air 10 through a gap 1 in the lower region and in the axial direction of the reaction space and by the injected fluid.

  • a pure fluid, solution, molten mass, or the like is sprayed into the solids flow 15 .
  • a wetting, coating, or a granulation or agglomeration of the material is performed corresponding to the end product to be produced.
  • the amount and the flow rate of the inlet air 10 supplied to the reaction space 26 and/or the air flow 12 can be set controllably, wherein in an advantageous way, two opposing circular solids flows 15 are generated in the reaction space 26 .
  • the formation of the solids flow 15 is supported by the injection of fluid and by the arranged separating plates 16 .
