Definitions

  • the invention relates to a device for pyrolysis of waste materials, in particular contaminated sites, with an indirectly heated pyrolysis reactor, from which a pyrolysis gas line is led to a combustion chamber.
  • a device of the type specified at the outset is described, for example, in AT-PS 3 46 997. From this document, however, it does not appear that the use of the pyrolysis gases in a conventional gas burner or in an internal combustion engine because of the composition of the pyrolysis gases and various admixtures contained in them are problematic in practice.
  • a self-sufficient pyrolysis system ie a system that is equipped with the necessary units for cleaning and using the pyrolysis gases, therefore requires a high investment.
  • Such an effort is not always economically justifiable, especially if the amount of the materials to be disposed of - as is often the case with contaminated sites - is limited so that the system can only be used for a limited period of time.
  • the invention has for its object to reduce the investment in a device of the type mentioned in the beginning and in particular to save the effort for cleaning the pyrolysis gases.
  • the solution according to claim 1 is particularly simple and cheap.
  • the solution according to claim 2 is intended for special cases in which the pyrolysis gas has more thermally stable substances, e.g. Dioxin, can contain, especially for the pyrolysis of PCB-containing residues from transformer oils.
  • Dioxin e.g. Dioxin
  • the feature of claim 3 also allows the use of the residual heat contained in the exhaust gases from the heating of the pyrolysis reactor.
  • the feature of claim 4 enables economically viable pyrolysis treatment of special wastes even if they can only be eliminated in a limited amount.
  • the feature of claim 5 enables the saving of additional fuel for the pyrolysis treatment. This is particularly important if the material to be pyrolytically treated has only a low energy potential.
  • FIGS. 1 and 2 each show a process diagram to illustrate the invention.
  • FIG. 1 - separated by a dashed line 1 - a conventional waste incineration system is shown, consisting essentially of a furnace 2, a steam boiler 3, a flue gas cleaning system 4, a suction 5 and a chimney 6.
  • the arrows drawn between the individual units represent symbolic represents the flue gas duct.
  • the invention is not tied to a specific system. It can be designed, for example, as roller grate or moving grate firing for the combustion of domestic and commercial waste or as a rotary kiln with or without an afterburner chamber for the combustion of industrial or special waste.
  • a pyrolysis reactor 7 is set up, preferably an indirectly heated rotary kiln, with feed lines 8 for fuel and combustion air.
  • the rotary kiln 7 is fed with waste material via a feed device 9, e.g. with oil-soaked soil. Solid residues are discharged via a discharge device 10.
  • the pyrolysis gas is passed through a pipeline 11, which is well insulated to avoid condensation and is as short as possible, into the furnace 2 and burned there in a burner, not shown, which serves as a support burner for waste incineration.
  • the flue gas from the burner mixes with the flue gas from the refuse furnace and contributes to heating the steam boiler 3.
  • the exhaust gas from the heating of the pyrolysis reactor 7 is introduced into the steam boiler 3 via an exhaust gas line 12 in the corresponding temperature zone, where it largely emits its heat content and mixes with the rest of the exhaust gas stream.
  • the entire flue gas is freed from solid and gaseous admixtures in the flue gas cleaning system 4 and is released into the open via the suction 5 through the chimney 6.
  • the plant illustrated in FIG. 2 is intended in particular for the disposal of waste materials which may contain harmful, thermally more stable substances, such as chlorinated biphenyls. It differs from the system according to FIG. 1 in that the pyrolysis gas is fed via a line 13 to a combustion chamber 14 which is separate from the furnace 2 and there at one temperature is burned separately above 1200 ° C. The high combustion temperature ensures that the harmful substances are safely decomposed. In the furnace 2, the usual flue gas temperature level of 800 to 900 ° C can be maintained. The flue gas produced in the combustion chamber 14 is introduced via a line 15 into the flue gas duct of the furnace 2 before entering the steam boiler 3.
  • the pyrolysis gas is fed via a line 13 to a combustion chamber 14 which is separate from the furnace 2 and there at one temperature is burned separately above 1200 ° C.
  • the high combustion temperature ensures that the harmful substances are safely decomposed.
  • the usual flue gas temperature level of 800 to 900 ° C can be maintained.
  • the pyrolysis reactor 7 is heated in the system according to FIG. 2 by means of a partial flow of hot flue gases, which branches off from the flue gas duct via a line 16 before entering the steam boiler 3 and is led to the pyrolysis reactor 7 via a hot gas filter 17.
  • the system shown schematically in FIG. 2 corresponds to the system described first. It is of course also possible to heat the pyrolysis reactor with hot flue gas from the waste incineration plant if, as in the embodiment shown in FIG. 1, the pyrolysis gases are burned in the waste incineration plant.
