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 which the transport channel in a housing, in particular in a Pyrolysis reactor opens.
  • the transport device becomes thermal waste disposal used, especially after the smoldering process.
  • the procedure and one then working plant for thermal waste disposal are for example in US-A-5 220 873, in EP-A-0 302 310 and in DE-A-38 30 153.
  • 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 uses a waste transport device of the type mentioned above Waste into carbonization gas and pyrolysis residue.
  • the Smoldering gas and the pyrolysis residue are then made more suitable Refurbishing the burner of the high temperature combustion chamber fed. This creates molten slag that over a deduction is removable and the glazed after cooling Form is present.
  • the resulting flue gas is fed through a 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 object of the invention is therefore a transport device to train for waste of the type mentioned at the beginning, that a blockage can be quickly removed.
  • Farther is a method for inspecting the content of a transport channel for waste that flows into a housing that can be carried out easily and quickly.
  • the task with regard to the transport device is according to the invention solved in that the unit from stuffing screw and transport channel releasably attached to the housing, by means of a driving device is removable from the housing and that the Transport channel (8) is divided horizontally.
  • the unit is made of a stuffing screw and transport channel from the housing, in particular one Pyrolysis reactor, so the stuffing screw is light accessible so that a malfunction can be remedied there quickly can. If necessary, the stuffing screw can also be easily removed, so that a quick exchange is guaranteed. This is particularly important for repair work on the stuffing screw or important for maintenance work.
  • a type of wagon or a The carriage is movable on at least one rail is.
  • the movement can be done manually, but preferably mechanically be performed.
  • FIG. 1 is a transport device 2 for waste A. provided, in which a waste feed shaft 4 via detachable Fastening means 6 connected to a transport channel 8 is.
  • the transport channel 8 is here as a stuffing screw trough educated. It has a round, but preferably a polygonal Cross-section.
  • the transport channel 8 opens into a housing 10, in the present case in a pyrolysis reactor. Here it is a rotating around its longitudinal axis Smoldering drum with a larger number of heating pipes 12 is equipped parallel to the longitudinal axis.
  • a stuffing screw 14 is arranged, which is in the Extends in the longitudinal direction.
  • the shaft 16 of the stuffing screw 14 is driven by a motor 20 via a transmission 18.
  • Of the Waste feed shaft 4 is on the side of the transport channel 8 its end arranged.
  • Lockable ring seals 22 serve this purpose, on the one hand at the left end of a feed tube 24 that the transport channel 8 surrounds, and on the other hand on a flange 26 on the transport channel 8 are attached. It is also important that the Unit consisting of screw auger 14 and transport channel 8 on one Chassis or a driving device 28 is mounted. To this relatively heavy unit 14, 8 still belongs here Transmission 18 and the motor 20. In the driving device 28 acts it is a kind of carriage or a carriage which is mounted on Rails 30 is horizontally movable. There can be two or more rails 30 may be provided. The driving device 28 has at least three, but preferably four wheels 31.
  • the horizontal Movability is indicated by a double arrow 32.
  • the device 28 can be manually operated by an auxiliary device, but preferably by a machine (not shown) be moved.
  • the unit 14, 8, 18, 20 mentioned is thus, after the connection points 6, 22 are released, from Housing 10 removable.
  • the waste A in the rotating smoldering drum 10 by means of the heating tubes 12 indirectly from heating gas h heated.
  • This heating gas h is via a stationary heating gas inlet housing 40 into a hot heating gas chamber 42 inside the swelling drum 10 passed.
  • On the tube sheet wall 44 are the parallel heating tubes 12 with one end attached. The other end is in a tube sheet wall 46 the one wall of a cold heating gas chamber 48 forms.
  • the heating gas passes from this cold heating gas chamber 48 h via a heating gas outlet housing 50 into an outlet.
  • To seal the heating gas outlet housing 52 against that rotating tube ring seals 54, 56 are provided.
  • the latter can be according to the smoldering method using a suitable device (not shown) divided into different fractions and sorted out before being burned in a (not shown) High temperature combustion chamber is supplied.
  • a suitable device not shown
  • a releasable on the discharge device 64 Ring seal 66 arranged.
  • the drives 68 work here on races 72, which are arranged on the circumference of the smoldering drum 10 are.
  • the Transport channel 8 is preferably n-shaped, n is a number greater than four. In the present example an octagonal embodiment chosen.
  • the one in the transport channel 8 housed auger is again designated 14.
  • the transport channel 8 formed from an upper and a lower shell part 8a and 8b becomes.
  • the transport channel 8 is thus divided horizontally educated.
  • the two shell parts 8a, 8b by screw fasteners 74 attached to longitudinal flanges are held together. If necessary, these are screw connections 74 easily detachable. Then the upper shell part 8a can be lifted off slightly and the interior inspected.
