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 object of the invention is to provide a transport device for Form waste of the type mentioned in such a way that at least a supply line leading from the outside into the pyrolysis reactor should lead, with comparatively little effort can be relocated.
- the object is achieved by the technical features of claim 1.
- In particular is in the room between the housing of the transport channel and the pyrolysis reactor at least one leading from the outside into the pyrolysis reactor Supply line arranged.
- Blockage of the stuffing screw should be avoided if possible become.
- the housing has a circular cross section, for example.
- the housing has a polygonal shape Cross-section.
- This polygonal cross section can be a trough-shaped cross section with a lower polygonal Part and an upper rectangular part. He can also be a polygon with sides of equal length.
- the supply line or lines can be all possible Serve purposes, for example the air supply in the Pyrolysis reactor.
- FIG. 1 is a transport device 2 for waste A. provided at a drop chute or waste feed chute 4 via releasable fastening means 6 to a fixed one Transport channel 8 is connected.
- the transport channel 8 is here designed as a stuffing screw trough.
- Has housing 8a a preferably polygonal cross-section, as can be seen from Figure 2.
- the longitudinal axis of the housing 8a is designated by 9.
- the transport channel 8 opens into a pyrolysis reactor 10, in in the present case in a rotating around its longitudinal axis 11 Smoldering drum with a larger number of heating pipes 12 is equipped parallel to the longitudinal axis 11.
- the heating pipes 12, of which only two in FIG. 1 and forty-eight in FIG are shown, are charged with heating gas h to Example with hot air. You are in a 12s front ring moored, to which an input pipe 13 connects concentrically.
- the end of the transport channel 8 is concentric in this input tube 13. As will be explained below, a good seal is
- 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.
- the escape rooms 34 are located usually above or to the side of the screw conveyor 14.
- the waste A in the rotating smoldering drum 10 by means of the heating pipes 12 indirectly from the heating gas h heated.
- This heating gas h is via a stationary heating gas inlet housing (not shown) passed into the smoldering drum 10.
- a stationary heating gas inlet housing (not shown) passed into the smoldering drum 10.
- Heating tubes 12 attached with one end.
- the other end is in the tube sheet wall 12s moored that part of the wall a "cold" heating gas outlet housing 50 forms.
- This Housing 50 passes the heating gas h into an outlet.
- ring seals 52 or 54 are provided for sealing of the hot gas outlet housing 50 against the rotating Tube 10 and the input tube 13 ring seals 52 or 54 provided. Accordingly, to seal the Heating gas inlet housing (not shown) ring seals intended.
- the latter can be done according to the smoldering-burning method by means of a suitable device (not shown) in different combustible and inert fractions divided and sorted out be before the combustible portion of a combustion in a high temperature combustion chamber (not shown) becomes.
- At least one supply line 32 in the space 30 between the housing 8a of the transport channel 8 and the pyrolysis reactor 10 (or its inlet tube 13) also one Disposal line can be arranged.
- This disposal line can be used, for example, as a suction pipe for discharge of water vapor from the interior of the pyrolysis reactor 10 serve.
- the arrangement of a supply and / or disposal line 32 instead of at the entrance can also be provided at the outlet of the pyrolysis reactor 10, using an output pipe that joins the input pipe 13 corresponds.
