Definitions

  • the invention relates to a method for binding pollutants according to the preamble of Claim 1.
  • This object is achieved according to the invention by a method according to claim 1, according to which at least one water-containing substance is used to bind pollutants in production processes in foundry systems in the production process, this water-containing substance partially consisting of H 2 O 2 according to the invention and the water-containing substance being foundry sand.
  • the binding can take place in a chemical oxidation or reduction reaction.
  • the hydrogen peroxide is a comparatively unstable substance that enters a water molecule as well as a single oxygen atom decays. This single oxygen atom acts as a free one Radical chemical reactions quickly occur. By adding Hydrogen peroxide can therefore be released by oxidation.
  • This Pollutants can be organic substances such as benzenes. There is also one Cleaning of dust is conceivable.
  • the foundry sand is in the ongoing production process is used.
  • the foundry sand is located in Circulation. After running through the production process, the foundry sand is passed through Addition of new substances processed so that this foundry sand is used in the production process has the desired composition.
  • H 2 O 2 can advantageously be added to the foundry sand in this preparation.
