Definitions

  • the invention relates to a process for the preparation of heavy-duty detergents and heavy duty detergent components in granular or agglomerate form on a dry basis in a substantially horizontally oriented fluidized bed.
  • the disadvantage is that, depending on the quality of the mixture of the individual components a more or less inhomogeneous distribution of different components takes place. During transport and at the Storage can easily cause segregation of the components within the packaging or the container come. Due to the high dust content and the tendency to segregate will increase the quality of the detergent or detergent components deteriorated considerably. This works are very disadvantageous because these dusts in the most common cases are classified as harmful to health. Furthermore, there is with decreasing particle size increases in tendency to Dust explosions.
  • the object of the invention is to provide a method for Production of heavy-duty detergents and heavy-duty detergent components to develop in granular or agglomerated form on a dry matter basis, which is compared to the known granules by a homogeneous Composition of the granules or agglomerates of the individual Raw material components including the binder and the moisture characterized, a high resistance to mechanical stress has good water dispersibility and is low in dust are virtually dust-free.
  • the product is produced by fluidized bed agglomeration / granulation in a substantially horizontal aligned fluidized bed.
  • This is the solid in the Fluidized bed via a Bedüsungssystem a binder and / or Components in the form of solutions, suspensions or melts fed.
  • the binder content in the product can be 1 to 35% by weight.

  • the powdery starting material is on the solids entry 2 and a rotary valve 12 as a pressure seal to the environment of first process stage in the field of the fluid space II of the fluidized bed fed.
  • the supplied material goes through different process stages such as heating, agglomerating, coating, drying and cooling.
  • process air 1 with different Temperatures over the Zu Kunststoffschn 10 and an air distribution floor 11 of the fluidized bed 9 fed.
  • the supply air chambers form this 10 and the air distribution floor 11, as an upper limit, the Anströmteil 1, in which the process air 1 in the swirl space II introduced, distributed and evened out.
  • the temperature of the process air 1 for the agglomeration of the product is dependent on the decomposition temperature of each introduced Substance components and lies according to the substance components between 20 to 300 ° C.
  • the process air 1 for the cooling of the already granulated and dried material will be at the end of the process stages fed in front of the region of the product discharge 3.
  • the temperature the process air 1 for cooling is between - 20 to + 30 ° C and also depends on the individual fabric components in the final product. This will give the process optimal conditions in the fluidized bed 9 by adjusting the respective layer temperature created.
  • the vortex space II is in the lower area through the air distribution floor 11 with a substantially rectangular base and formed by vertical to slightly inclined side walls. there the side walls of the spinal space II can reach max. 10 ° from the Vertically inclined.

  • the spray system 8 is a homogeneous solid mixture, wherein Granules with a homogeneous composition of the respective Individual components are formed.
  • the expansion zone III closes on, in which the flow velocity of the process air 1 through Cross-sectional extensions is reduced.
  • the side walls of the Expansion zone III show a strong inclination of 15-45 ° Vertical on, so that a cross-sectional widening to the subsequent filter system IV takes place.
  • the expansion zone III is followed by an integrated filter system IV for dedusting the process air 1 and the simultaneous Return of the dust to the underlying fluidized bed 9 at.
  • the filter system IV consists of filter elements 7, the mechanically through the filter cleaning 6 and / or by compressed air 5 can be cleaned impulsively. The use of other well-known Filter elements is possible. Due to the integrated filter system IV Contact with the dusts is avoided and the dust explosion hazard reduced to the interior of the fluidized bed apparatus.
  • the purified process air leaves the system as exhaust 4 during the finished product also via a rotary valve 12 as Pressure completion via the product discharge 3 discharged from the system becomes.
