Definitions

  • the invention relates to a process for the treatment of slag in waste incineration plants according to the preamble of claim 1 and to a waste incineration plant according to the preamble of claim 9.
  • grate furnaces are predominantly used, wherein the hot raw slag is usually discharged by means of a so-called wet purifier from a space downstream of the combustion chamber.
  • the wet slagger forms a sluice, in the manner of a siphon to the air close to the separation of the firebox, more precisely of the firebox downstream, air-conductively connected to the combustion chamber space or the combustion air from the outside air.
  • wet slagters used have a negative side effect with regard to the external treatment, since they support unwanted reactions such as agglomeration of the fine slag particles into slag-containing slag, which makes subsequent metal recovery from the raw slag difficult.
  • various concepts have been developed with different objectives for improving waste incineration plants. So it is for example from the EP 0 437 679 A1 It has become known to separate the raw slag after passing through the fire grate into two fractions, wherein the further treatment of these fractions takes place outside the incinerator by the fraction with components whose diameter is smaller than 100 mm to 300 mm, is melted in a separate furnace.
  • the EP 0 722 777 A1 EP-A-0 416 841 discloses a method for treating slags from waste incineration plants, after which the raw slag, after passing through the grate, is separated directly and without prior quenching in a water bath into at least two fractions.
  • the coarse fraction is fed to a wet slagger, wherein a screen overflow is separated from the fine fraction and also fed to the wet slag.
  • the screen diarrhea is fed to a second screening stage, for the separation of a fine fraction of 0 mm to 2 mm.
  • the screen overflow of the second stage is optionally mechanically comminuted after sorting out of metallic and inert materials, wherein the screen diarrhea is a special treatment, for example, fed to a melting furnace.
