Definitions

  • the invention relates to a method for the thermal treatment of waste contaminated with organic components. First and foremost, it is about the processing of metal scrap, namely the scrap that accumulates in a car shredder, in particular also aluminum scrap that is contaminated by the organic plastics used in automobile construction.
  • DE 36 35 068 C2 discloses a method for the thermal disposal of material contaminated with pollutants. Earth, waste, hazardous waste and sewage sludge are mentioned as examples of goods to be disposed of.
  • all volatile substances in the well are converted into gas and / or vapor form and separated from the solid disposal products, the volatile substances resulting from the degassing process being separated from the solid degassing products before they are used to burn the solid degassing products at the high-temperature stage are fed, passed over a fixed coke bed operated at temperatures of about 1200 ° C reducing with exclusion of air and then further cleaned.
  • the use in the treatment of metal scrap in particular is not mentioned in the known method.
  • a high-temperature gasification stage is also known as a single system. However, a high proportion of free primary energy is required.
  • the invention is based on the object of specifying a method or a system for the thermal treatment of waste contaminated with organic components, in which, in addition to the reusable substances, waste materials to be disposed of with as little energy expenditure as possible are generated with as little effort as possible.
  • the pyrolysis gas produced in the smoldering stage is cleaned in the subsequent high-temperature gasification stage and converted to the marketable products heating gas and glazed slag.
  • the supply of primary energy to the high-temperature gasification stage is minimized by the supply of the pyrolysis gas produced in the carbonization stage and, depending on the proportion of organic substances, can even go to zero.
  • the heating gas obtained in the high-temperature gasification stage is freed of undesired components in a gas cleaning system before it is used for energy purposes.
  • a denitrification system and a dioxyn filter can then be dispensed with under certain circumstances. If a gas cleaning system is arranged, the gas is of course returned to the carbonization stage after the gas has been cleaned.
  • the invention also relates to a plant for carrying out the method described in claims 2 to 5.
  • the above statements relating to a method apply mutatis mutandis.
  • the scrap 1 contaminated with organic components is fed to a pre-comminution system 2 and comminuted there to piece sizes of a maximum of 5 cm. Larger pieces can be returned to the entrance of the pre-shredding unit 2.
  • the shredded scrap is then fed to a carbonization stage 3, which is operated at a temperature of approximately 550 ° to 600 ° C.
  • the level 3 is possibly Energy 21 and air or oxygen 22 supplied.
  • the solids 5 are separated from the pyrolysis gas 4 by pyrolysis.
  • the solids 5 are then separated into reusable metal 7 and pyrolysis coke 8 in a mechanical processing stage 6.
  • the cleaned metal 7 can be fed to a smelter as pure scrap.
  • the pyrolysis coke 8 comes into a high-temperature gasification stage 14.
  • the pyrolysis gas 4 also comes from the carbonization stage 3.
  • the high-temperature gasification stage 14 also has supply lines for energy 23 and an oxidizing agent 9, e.g. Air or oxygen, and possibly also for coke 10.
  • the pyrolysis gas 4 is supplied via a burner.
  • the treatment in the high-temperature gasification stage 14 takes place at a temperature of approx. 1600 ° C.
  • a glazed building material 19 and energy 20 are obtained, which can be given to consumers.
  • the heating gas 11 obtained in the high-temperature gasification stage 14 is fed to a gas cleaning system 13, where it is freed of undesirable additions, for example of HCl, HF, dust and dust constituents.
  • the gas purified in this way is then used for energetic purposes 12, e.g. in the form of a boiler.
  • a portion 17 of the cleaned gas is returned to carbonization stage 3 and minimizes the supply of primary energy.
  • the energy obtained in the energetic use 12 is given to the consumer together with the energy 20 obtained in the high-temperature gasification stage.
  • a flue gas desulfurization system 16 is connected downstream of the energetic use 12, but this only happens as required.
  • the flue gas desulfurization system 16 can also be supplied with the flue gas 18 obtained in the carbonization stage 3. After desulfurization, the flue gas 24 goes into the atmosphere, optionally with the interposition of further filters.
  • the invention has been explained above on the basis of the processing of metal scrap. However, the invention can also be used in the treatment of other waste, domestic waste and special waste.
