Definitions
- the invention relates to a transport device for waste, in which a waste feed shaft is connected to a transport channel, in the longitudinal direction of which a stuffing screw driven by a motor is arranged, and in which the transport channel is placed in a pyrolysis reactor, in particular in a Smoldering drum rotatable about its longitudinal axis, opens out.
- the transport device is used for thermal waste disposal, in particular after the smoldering-burning process.
- the essential components of the plant for thermal waste disposal using the smoldering-firing process include a pyrolysis reactor and a high-temperature combustion chamber.
- the pyrolysis reactor converts the waste which is fed in via a waste transport device of the type mentioned in the below-stoichiometric carbonization process into carbonization gas and pyrolysis residue.
- Smoldering gas and the pyrolysis residue are then fed to the burner of the high-temperature combustion chamber after suitable work-up.
- Molten slag is formed here, which can be removed via a fume cupboard and which, after cooling, is in a glazed form.
- the resulting flue gas is fed to a chimney as an outlet via a flue gas line.
- a flue gas line in particular a heat recovery steam generator as a cooling device, a dust filter system and a flue gas cleaning system are installed.
- a gas compressor in the flue gas line which is arranged directly at the outlet of the flue gas cleaning system and can be designed as a suction fan.
- the built-in gas compressor is used for Maintaining a vacuum, even if only slight, in the pyrolysis drum. This negative pressure prevents carbonization gas from escaping to the outside through the ring seals of the pyrolytic drum.
- Waste of various types for example comminuted domestic waste, industrial waste similar to domestic waste and comminuted bulky waste, but also dewatered sludge, is fed to the smoldering drum by the transport device.
- the transport device for waste can be blocked or disrupted if too large waste particles fall into the helix of the transport or stuffing screw from the waste feed shaft. Avoiding a blockage of the stuffing screw is necessary for continuous operation, however, as a rule new garbage or waste is delivered continuously. For smooth transport of the waste, it is also necessary that it does not stick to the screw conveyor and that it rotates with the screw spiral. In order to achieve this, it is customary in the case of transport screws that strips are arranged in the housing on the wall thereof, which protrude into the space between the transport screw and the housing. When the transport screw rotates, the goods to be transported are prevented from rotating by the bars of the transport screw. However, such strips are subject to high wear.
- DE-A-38 30 153 discloses pyrolysis reactors with a heating device for waste, in which supply lines for the direct heating of the waste in the smoldering drum are provided at the end with outlet nozzles for air. These supply lines are led through a heating gas housing on the smoldering drum.
- the known constructions require special and therefore complex sealing measures.
- the object of the invention is to design a transport device for waste of the type mentioned in the introduction such that at least one supply line which is to lead from the outside into the pyrolyzer reactor can be laid with comparatively little effort.
- the object is achieved in that at least one supply line leading from the outside into the pyrolysis reactor is arranged in the space between the housing of the transport channel and the pyrolysis actuator.
- Blockage of the stuffing screw should be avoided if possible.
- the housing has, for example, a circular cross section.
- the housing has a polygonal cross section.
- This polygonal cross section can be a trough-shaped cross section with a lower polygonal part and an upper rectangular part. It can also be a polygon with sides of equal length.
- the supply line or lines can serve all possible purposes, for example the air supply to the pyrolysis reactor.
- the pyrolysis reactor is connected on the input side to an input tube, that the end of the transport channel is sealed and arranged in a stationary manner within the input tube, and that the supply line is led through the space between the input tube and the transport channel.
- the transport device can be used at the entrance and / or exit of the pyrolysis reactor.
- a transport device for the introduction or discharge of waste into or from a pyrolysis reactor which can be rotated about its longitudinal axis and which is preferably characterized by a) a tube fastened to the pyrolysis reactor and connected to the pyrolysis reactor by its Longitudinal axis can also be rotated, b) a sealing ring attached to the end of the tube, c) a fixed transport channel protruding into the tube, d) a counter ring attached to the outer circumference of the transport channel for the sealing ring and e) at least one supply line, which is connected from the outside leads into the interior of the pyrolysis reactor via the space between the housing of the transport channel and the pipe.
- Figure 1 shows a transport device for waste as part of a smoldering plant in a longitudinal section
- FIG. 2 shows a lateral section in the direction II-II of FIG. 1.
- a transport device 2 for waste A in which a drop shaft or waste feed shaft 4 is connected to a fixed transport channel 8 via releasable fastening means 6.
- the transport channel 8 is designed here as a stuffing screw trough.
- Its housing 8a has a preferably polygonal cross section, as can be seen in FIG.
- the longitudinal axis of the housing 8a is designated by 9.
- the transport channel 8 opens into a pyrolysis reactor 10, in the present case in a smoldering drum rotating about its longitudinal axis 11, which is equipped with a larger number of heating tubes 12 parallel to the longitudinal axis 11.
- the heating tubes 12, of which only two are shown in FIG. 1 and forty-eight in FIG.
- heating gas h for example with hot air. They are fixed in a front ring 12s, to which an inlet 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 ensured.
- a transport or stuffing screw 14 is arranged in the interior of the transport channel 8, which is stationary during normal operation, and whose longitudinal axis 15 extends in its longitudinal direction.
- the shaft 16 of the plug screw 14 is driven by a motor 20 via a gear 18.
- the waste feed shaft 4 is arranged laterally from or vertically above the transport channel 8 at its end.
- the filling opening for waste is designated 22 and the discharge opening 24.
- a central section 14a of the screw conveyor 14 has a smaller pitch than the rest of the screw conveyor 14 or the starting piece 14b. This ensures that the transported waste A in the area of this middle section 14a is compressed more than in the other areas, which means that in the area of section 14a of the transport screw 14 practically the entire subspace in the housing 8a of the transport channel 8 the waste A is filled.
- the transported waste A itself closes the housing 8a there in a gas-tight manner. Neither air can then flow from the filling opening 22 to the discharge opening 24, nor can carbonization gas flow in the opposite direction.
- the transport screw 14 In the transport direction behind the compression zone, which is located in the region of section 14a of the transport screw 14, the transport screw 14 again has a larger incline. The package of waste A, which extends over the entire cross section of the transport channel 8, is thereby dissolved again.
- FIG. 2 there are three supply lines 32 here.
- the space 30 under consideration here lies between the housing 8a and the inlet pipe 13.
- the supply lines 32 lie here in the “free corners” outside the housing 8a.
- the supply lines 32 are provided, for example, for introducing air 1, inert gas, water or water vapor, which can be overheated.
- the air 1 introduced can be used for the partial combustion of carbonization gas in the py rolysis reactor 10 serve.
- Two air outlet or burning nozzles on the supply line 32 are designated 35 in FIG.
- a mechanical seal 40 is arranged at the end of the inlet tube 13. It consists of a rotating sliding ring 42 and a stationary counter ring 44, both of which can be made of steel.
- the counter ring 44 is fastened on a ring 46 which is welded to the housing 8 a by means of a weld seam 48.
- the transport device 2 In order to be able to close the housing 8a of the transport channel 8 in a gas-tight manner by the transported waste A, the transport device 2 should be operated with full filling. So that relatively large, hard parts of the waste A cannot block the transport screw 14, differently configured and configured alternative spaces 34 for such relatively large parts can be provided within the housing 8a due to the geometric shape. In other words: the transport channel 8 can have not only the polygonal cross section shown, but also other cross sections. When the screw conveyor 14 rotates, the relatively large parts to be transported are pressed into these alternative spaces 34 and transported along with the longitudinally moving waste A in the alternative spaces 34, so that they cannot block the screw conveyor 14. The escape spaces 34 are generally located above or to the side of the screw conveyor 14.
- the waste A in the rotating carbonization drum 10 is heated indirectly by the heating gas h by means of the heating pipes 12.
- This heating gas h is passed into the smoldering drum 10 via a stationary heating gas inlet housing (not shown).
- the parallel heating tubes 12 are attached at one end. The other end is in of the tube sheet wall 12s, which forms part of the wall of a "cold" hot gas outlet housing 50.
- the heating gas h passes from this housing 50 into an outlet.
- Ring seals 52 and 54 are provided to seal the heating gas outlet housing 50 against the rotating pipe 10 and the inlet pipe 13.
- ring seals are provided for sealing the heating gas inlet housing.
- a discharge tube (not shown) is led into the interior of a fixed discharge device.
- the carbonization material that arrives in this discharge device via the discharge tube is divided there into carbonization gas and residual material.
- the latter can be divided into various combustible and inert fractions and sorted out according to the smoldering-firing method using a suitable device (not shown) before the combustible portion leads to combustion in a high-temperature combustion chamber (not shown) becomes.
- a disposal line can of course also be arranged in the space 30 between the housing 8a of the transport channel 8 and the pyrolysis reactor 10 (or its inlet pipe 13).
- This disposal line can serve, for example, as a suction pipe for the removal of water vapor from the interior of the pyrolysis reactor 10.
- the arrangement of a supply and / or disposal line 32 can also be provided at the outlet of the pyrolysis reactor 10 instead of at the inlet, using an outlet pipe which corresponds to the inlet pipe 13.
