Definitions

  • the invention relates to a transport device for Waste, in which a waste feed shaft is connected to a transport channel is connected, in the longitudinal direction one of one Motor drivable stuffing screw is arranged, and at the the transport channel into a pyrolysis reactor, in particular in a smoldering drum rotatable about its longitudinal axis.
  • the transport device becomes thermal waste disposal used, especially after the smoldering-burning process.
  • the procedure and a plant for thermal waste disposal operating afterwards are for example in EP-A-0 302 310 and in DE-A-38 30 153 and also described in EP-A-0 360 052.
  • the plant for thermal waste disposal after the smoldering process contains as essential components a pyrolysis reactor and a high-temperature combustion chamber.
  • the pyrolysis reactor puts the over a waste transport device of the type mentioned discarded waste in a substoichiometric process Smoldering process in carbonization gas and pyrolysis residues.
  • the Smoldering gas and the pyrolysis residue are then made more suitable Refurbishing the burner of the high temperature combustion chamber fed.
  • Flue gas line fed to a chimney as an outlet.
  • Flue gas pipes are in particular a heat recovery steam generator as a cooling device, a dust filter system and a flue gas cleaning system built-in.
  • a gas compressor which is located directly at the exit of the Flue gas cleaning system arranged and as a suction fan can be trained.
  • the built-in gas compressor is used for Maintenance of a vacuum, even if only slight in the pyrolysis drum. Because of this negative pressure prevents carbonization gas through the ring seals of the pyrolysis drum leaks out into the environment.
  • the transport device makes waste different kind, for example shredded household waste, more like household waste Industrial waste and crushed bulky waste, but also dewatered Mud fed to the smoldering drum.
  • Waste transport equipment blocked or disrupted may be too large waste particles from the waste feed chute fall into the helix of the transport or stuffing screw. Avoiding a blockage of the stuffing screw is for continuous operation is required, as it is usually continuous new garbage or waste delivered. For one smooth transportation of waste it is also necessary that it does not adhere to the screw conveyor and engages with the helix turns. To achieve that, it is at Transport screws usual that strips in the housing on the wall are arranged in the space between the screw conveyor and protrude housing. If the screw conveyor rotates, the goods to be transported are passed through the bars of the screw conveyor prevented from turning. However, such strips are subject to high wear.
  • DE-A-38 30 151, DE-A-38 30 152 and the DE-A-38 30 153 are pyrolysis reactors with a heating device for Known waste where supply lines for direct End heating of the waste in the smoldering drum Air outlet nozzles are provided. These supply lines are by a heating gas housing on the smoldering drum guided.
  • the known constructions require special and therefore complex sealing measures.

  • the Longitudinal axis 15 extends in the longitudinal direction.
  • the Shaft 16 of the plug screw 14 is via a gear 18 from driven by a motor 20.
  • the waste feed chute 4 is laterally from or vertically above the transport channel 8 on the latter Arranged at the end.
  • the filling opening for the waste is included 22 and the discharge opening designated 24.
  • the transported Waste A closes the housing 8a there gas-tight. It can then neither air from the fill opening 22 to the discharge opening 24, still flow carbonization gas in the reverse direction.
  • the screw conveyor 14 In Direction of transport behind the compression zone, which is in the Area of the section 14a of the screw conveyor 14, the screw conveyor 14 has a larger slope again. Which over the entire cross section of the transport channel 8 itself this extends the package of waste A again.
  • a mechanical seal 40 is arranged at the end of the inlet pipe 13 .
  • she consists of a rotating sliding ring 42 and a stationary Counter ring 44, both of which can be made of steel. Of the Counter ring 44 is fixed on a ring 46, which with the help a weld seam 48 is welded to the housing 8a.
  • the Transport device 2 are operated fully filled.
  • the screw conveyor 14 can not block, can within the housing 8a different due to the geometric shape located and configured alternative spaces 34 for such relative large parts can be provided.
  • the Transport channel 8 can not only the polygonal shown Cross section, but also have other cross sections.
  • the relatively large, parts to be transported are pressed into this alternative space 34 and with the longitudinally moving waste A in the Evacuation spaces 34 transported, so that they are the screw conveyor 14 can not block.
