Definitions

  • the invention relates to a method for disposing of glass fiber reinforced components, such as e.g. Rotor blades of wind power machines with a base made of fiber-reinforced plastics.
  • Rotor blades for wind turbines usually consist of a base made of glass-fiber reinforced plastics, wherein in addition to the plastics primarily inorganic compounds are essential components of the rotor blades.
  • Rotor blades are attracting increased attention in recent times as existing substances, with the preparation and disposal of such rotor blades is very problematic due to their composition and size.
  • On the other hand when comminuting or cutting such rotor blades, extremely fine dust-like particles are formed which make handling difficult and pose a health risk.
  • the invention now aims to provide glass fiber reinforced components, e.g. Rotor blades for wind turbines with a base made of fiber-reinforced plastics to dispose of economically meaningful way and to ensure the fullest possible use of the starting materials, as used in rotor blades.
  • the method according to the invention essentially consists in that the rotor blades are supplied as an alternative fuel to a clincher manufacturing process.
  • the utilization of rotor blades in the cement industry is particularly advantageous because the plastic component of the rotor blades is a good alternative fuel and the post-combustion fiberglass component gives inorganic combustion products that match the starting materials used in clinker production.
  • the inventive method is therefore further developed such that the rotor blades are comminuted to a fraction size of ⁇ 50 mm and mixed after at least partial separation of iron and non-ferrous metals with an alternative fuel having a water content of> 20 wt.% And homogenized and as alternative fuel to a clinker manufacturing process.
  • an alternative fuel having a water content of> 20 wt.%
  • homogenized and as alternative fuel to a clinker manufacturing process In a cutting or crushing to a fraction size of ⁇ 50 mm, relatively high levels of small, respirable dust particles, which complicate the handling.
  • the comminution can be made multi-stage and in the dry state still a separation of ferrous and non-ferrous metals can be made to be mixed with proven, wet fuels, it succeeds to bind the dust-like particles and to achieve intensive mixing and homogenization by means of a corresponding mixing technique, with the result that the mixture can be used in a particularly simple manner for clinker production.
  • the method according to the invention is further developed in that the weight ratio of rotor blades used to alternative fuel is greater than or equal to 1: 2. This will ensure that the Dust is bound during comminution and thus does not pose any danger to the personnel. In general, the more the water-containing alternative fuel is used, the better the inclusion of the dust. Thus, weight ratios of 1: 3 and 1: 4 and more are conceivable.
  • the method according to the invention is further developed such that the glass-fiber-reinforced components or the rotor blades are used in the calciner of the cement process.
  • the relatively homogeneous mixture provided by the mixing leads to an intensive incorporation of the inorganic substances, as present in the rotor blades as well as in the spit materials or the alternative fuel.
  • the method is therefore further developed such that the amount of glass fiber reinforced components used or the rotor blade fractions is determined and that the use of inorganic correction materials such as sand and chalk in the raw meal is reduced according to the amount of glass fiber reinforced components used.
  • Based on the analysis of such rotor blades it is possible to dispense with the use of 1250 t of natural sand and about 750 t of chalk per year when using 10,000 t of rotor blades per year. At the same time, about 7,000 t of lignite can be saved as fuel. In the oxidizing furnace atmosphere, the organic components are completely burned, thus making optimum use of the calorific value of the starting materials.
  • rejects and / or paper sludge from the paper industry and / or other production waste can be used.
  • the rejects in the material mixture also include films and plastics as well as textiles, filling or coating pigments from graphic papers, polystyrene from packaging materials, coating materials, composites, foreign substances from everyday office life and garbage-like defects from the municipal paper bin as well as paper scraps and sand.
  • Direct landfilling of such a substance mixture is, among other things, out of the question due to the relatively high calorific value.
  • the relatively high moisture content of the rejects is particularly suitable to bind finely divided and dust-like particles from the comminution of the rotor blades and to facilitate the manipulation of this mixture.
  • the heavy metal loadings of the rejects and paper and fiber sludge move in comparable fluctuation ranges as the corresponding heavy metal components in the inorganic part of the rotor blades, so that a simple adjustment of the maximum permissible load in the clinker is made possible.
  • the utilization of the above-mentioned rejects as well as the shredded rotor blades thus represents a positive energy contribution in the cement production as well as an environmental contribution, in which the idea of sustainability is taken into account and natural resources are spared.
  • the recipe for cement production is calculated taking into account all raw materials and combustion residues entered in the process. From the analysis, it can be seen that in the rotor blade fraction, almost 50% of the residues, mainly SiO 2 and CaO, remain in the clinker and are thus incorporated into the product.
  • multi-stage processes can be used, whereby the final comminution in so-called Stromzerspanern on a fraction size ⁇ 50 mm can be made.
  • the combustion energy of rotor blades could be determined on typical embodiments between 14 and 16 MJ / t.
  • the main elements in the ashes were determined with about 25 wt.% SiO 2 , 6 wt.% Al 2 O 3 , 14 wt.% CaO and small amounts of other oxides, thereby improving the usefulness as an inorganic correction substance in the clinker or Cement production results directly.
