Definitions
- the invention relates to a method for recycling organic Components containing waste materials through autothermal Gasification with the characteristics of the generic term of Claim 1.
- Such a method is particularly suitable for disposal of contaminated residues, since under the conditions of a High temperature gasification all in the contaminated residues contained pollutants are thermally split, a Formation of aromatic, polycyclic, heterocyclic or halogenated hydrocarbons excluded and the Mineral residues are melted and converted into a practically non-leachable form are transferred.
- the high temperature gasification such as. B. entrained-flow gasification
- waste materials which due to their nature do not or are difficult to grind, can hardly be achieved without pretreatment.
- To such commodities include extremely heterogeneous substances such as Household waste that contains both difficult-to-grind components such. B. Contain plastic foils as well as metals.
- Used tires that contain metals, which are used before grinding are to be removed sensibly. It is known this Waste before gasification by an upstream or in to pre-treat the gasification process integrated pyrolysis.
- the Pyrolysis products are in the subsequent gasification preferably with technically pure oxygen or a Oxygen / air / mixture implemented. Such a pyrolysis process is with an increased technical effort and with the possible Formation of toxic gases associated.
- the invention is based, for the generic Procedure to create a simplified procedure with the Help heterogeneous waste materials with not or difficult to grind Components are entered in the gasification reactor can.
- the effect of Embrittlement due to the known low-temperature treatment exploited to create a heterogeneous raw material like household waste processed in a high temperature gasification, without to have to apply a complex pretreatment by pyrolysis.
- the waste materials are removed by the low-temperature treatment embrittled so that the organic components of household waste then easily separated from metallic components, can be crushed and gasified.
- a side effect can largely pure metal can be obtained.
- the waste is reduced to one suitable grain size crushed.
- This grain size is determined after that the residence time of the shredded waste in the gasification reactor for the complete conversion of the organic components and the melting of the mineral and any metallic components that may still be present is sufficient.
- the shredded waste material is passed through a Screw extruder entry and / or a slurry entry and / or a dry dust lock entry into the gasification reactor fed.
- any inert coolant especially in the form of a frozen or one liquefied low-boiling gas
- Nitrogen is preferably used, which in a Air separation plant is obtained using the gasification plant is coupled and which serves as a gasifying agent Delivers oxygen. In this case, the nitrogen needed for the gasification process itself is worthless, used cheaply will.
- the Waste materials can also be carried out with carbon dioxide. This Carbon dioxide can be removed from the in a purification stage Gasification reactor generated fuel gas are separated.
- the Cooling of the carbon dioxide to the required Embrittlement temperature of the waste material takes place in one separate refrigeration system.
- the energy required to operate the Refrigeration system is preferably on the gasification system covered by the fuel gas generated in the gasification reactor burned and the heat contained in it is exploited.
