Definitions

  • the invention relates to a around its longitudinal direction rotatable heating chamber for solid goods, especially on a Smoldering drum for waste, with a number inside Heating pipes, each with one end on a first End plate and the other end to a second end plate are attached.
  • the heating chamber is used in particular as a smoldering drum for waste used for the purpose of thermal waste disposal, preferred after the smoldering process.
  • the plant for thermal waste disposal using the smoldering-burning process contains a as essential components Smoldering chamber (pyrolysis reactor) and a high-temperature combustion chamber.
  • the smoldering chamber uses a waste transport device abandoned waste in carbonization gases and pyrolysis residues around. The carbonization gases and the pyrolysis residues are then, after suitable work-up, the burner of the high-temperature combustion chamber fed. In the high temperature combustion chamber creates molten slag that over a Deduction is removed and after cooling in glassy Form is present.
  • the resulting flue gas is fed through a flue gas line fed to a chimney as an outlet.
  • a flue gas pipe In this flue gas pipe are in particular a waste heat generator as a cooling device, a dust filter system and a flue gas cleaning system built-in.
  • a waste heat generator as a cooling device
  • a dust filter system as a cooling device
  • a flue gas cleaning system built-in.
  • a smoldering chamber (pyrolysis reactor) is usually one rotating, relatively long smoldering drum used has a large number of parallel heating pipes on the inside where the waste is largely heated in the absence of air becomes.
  • the smoldering drum rotates about its longitudinal axis.
  • the longitudinal axis is preferably somewhat opposite the horizontal inclined so that the solid char at the exit of the Collect the smoldering drum and from there via a discharge pipe can be carried out.
  • When turning the waste through the heating pipes are lifted up and fall down again.
  • waste becomes the transport of the solid (Dust, chunks of carbon (coke), stones, bottles, Metal, ceramic parts etc.) towards the discharge opening the smoldering drum accomplished.
  • the smoldering drum should be built relatively long. This means that the heating pipes in the interior must have an appropriate length. Depending on the material of these heating pipes and their length it can now happen that this - unless remedial measures are taken - in the interior sag. When the smoldering drum rotates this leads to alternating loads, so there is a risk can that the heating pipes torn out of their end bracket become. Especially with heating pipes, the one Can have a length of 20 to 30 meters or even more there is such a danger.
  • the invention is based on the consideration that at least one simple support point, but preferably at least two support points in the interior should be provided for supporting the heating pipes.
  • a support point will be able to be implemented in the form of a holder or pipe bushing.
  • this inevitably means that the free cross-section at the support point, which is required for the passage of the solid material and the carbonization gas, is reduced. This hinders the transport of the solid material and the carbonization gases - which can be significant under certain circumstances.
  • the object of the invention is therefore one about its longitudinal direction rotatable heating chamber for solid goods of the aforementioned To be designed in such a way that the heating pipes are supported is without the passage of the solid and the Smoldering gases is significantly impeded.
  • each support point is subdivided into p ⁇ 2 spaced partial supports, each with a console arrangement, each console arrangement comprising a plurality of support consoles lying in the same plane.
  • solid waste A via a feed or feed device 2 and a worm 4 driven by a motor 6 is driven and is arranged in a feed tube 7, centrally in a pyrolysis reactor or a smoldering chamber 8 brought in.
  • the smoldering chamber 8 is in the embodiment an internally heatable sill which can be rotated about its longitudinal axis 10 or pyrolysis drum, which have a length of 15 to 30 m can, which works at 300 to 600 ° C, which is largely below Oxygen is operated and in addition to volatile Smoldering gas s generates a largely solid pyrolysis residue f.
  • the pyrolysis drum 8 is on the output or discharge side a rotating central discharge pipe 17 a discharge device 18 downstream, with a carbonization gas discharge nozzle 20 for the discharge of the carbonization gas s and with a Pyrolysis residue outlet 22 for the discharge of the solid pyrolysis residue f is provided.
  • One at the smoldering gas discharge nozzle 20 connected carbonization line can be connected to the Burner connected to a high temperature combustion chamber.
  • the rotational movement of the smoldering drum 8 about its longitudinal axis 10 is effected by a drive 24 in the form of a gear, which is connected to a motor 26.
  • the drive means 24, 26 work, for example, on a ring gear on the circumference the smoldering drum 8 is attached.
  • the bearings of the smoldering drum 8 are designated by 27.
  • the heating tubes 12 each with one end at a first end plate 28 and with her other end are attached to a second end plate 30.
  • the attachment to the end plates 28, 30 is made so that preferred easy replacement of the heating pipes 12 results.
  • the end of the heating tubes 12 projects through an opening from the interior 13 to the left into the outlet chamber 16 or to the right into the inlet chamber 14.
  • the axis of the heating tubes 12 is perpendicular to the surface of the end plates 28, 30 aligned.
  • the individual heating tubes 12th are thermally and mechanically highly stressed, and that the end plates 28, 30, which are also called tube plates or drum tube plates could be referred to about the longitudinal axis 10 of the Turn smoldering drum 8 too.
  • Each of the console arrangements I, II, III contains several support or support consoles lying on the same level in the form of rounded perforated plates made of metal, for Steel example. These are shown in Figures 3 to 5 with the Reference numerals Ia, Ib, Ic, Id and IIa, IIb, IIc, IId and IIIa, IIIb, IIIc and IIId designated.
