Definitions

  • the invention relates to a around its longitudinal axis rotatable Smoldering drum for waste, with a number housed in the interior, approximately parallel to each other aligned heating pipes.
  • the heating chamber in particular for the purpose of thermal waste disposal used, preferably by 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 puts the over a waste transportation facility into carbonization gases and pyrolysis residues.
  • the smoldering gases and the pyrolysis residue are then more appropriate Refurbishing the burner of the high temperature combustion chamber fed.
  • the emerging Flue gas is sent to a chimney through a flue gas line fed as an outlet.
  • a heat recovery steam generator as a cooling device, a dust filter system and a flue gas cleaning system built-in.
  • a smoldering chamber pyrolysis reactor
  • a rotating, relatively long smoldering drum the inside a variety of parallel heating pipes where the waste is largely below Air closure is heated.
  • the smoldering drum turns itself around its longitudinal axis.
  • the Longitudinal axis slightly inclined to the horizontal, 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.
  • the waste is lifted up and down through the heating pipes down again. Through this and through falling waste the transport of the solid material (dust. chunks out Carbon (coke), stones, bottles, metal, ceramic parts, etc.) towards the discharge opening of the Smoldering drum accomplished.
  • the peripheral arrangement the - possibly irregularly spaced - Heating pipes could have a gap, for example at the point where there is an opportunity to inspect the smoldering drum consisted, for example, of Arrangement of a manhole. It should also be noted that the distance between two neighboring ones So far, heating pipes on the inner wall have been practically arbitrary was. This means that this distance was due to the design and a function of the heating surface required.
  • the object of the present invention is to design a heating chamber of the type mentioned at the outset in such a way that a sufficiently large heating surface in the form of heating tubes for heating or pyrolysis of the waste disposed is available in the region of the inner wall of the heating chamber.
  • the risk of jamming metal parts and other solid fragments should be greatly reduced, so that the side of the individual heating tubes facing the inner wall of the heating chamber can be optimally used for heat transfer.
  • the invention is therefore based on the consideration that the availability of a large heating surface ensures that the individual heating pipes on the Inside wall should be arranged as close as possible.
  • Words To prevent the above Being able to clamp chunks in the gap, should the heating pipes on the inside of the drum practically closed jacket, with a cylindrical So smolder drum form a tube circle. The distances between the individual heating pipes be chosen as narrow as possible.
  • the main advantages are to see that only fine waste material can fall on the inner wall of the heating chamber, and that this inner wall is practically not mechanically stressed becomes. Furthermore, in a pyrolysis reactor or a smoldering drum a good heat exchange from the heating pipes into the gas atmosphere and into the fines layer. The heat from the heating pipes radiated radially outwards becomes very great well used.
  • the heating chamber located heating pipes are protected against falling coarse material so-called impact shells made of a resistant material. This is in particular semi-cylindrical Peel.
  • Such protection can also be used for heating pipes be provided, which are - on straight or curved Lines (seen in cross section) - inside extend into the heating chamber.
  • the blind pipes mentioned above should have the same diameter as that on the inner wall arranged peripheral heating pipes.
  • the distance of the (preferably closed) pipe circle from the inner wall of the heating chamber should be as possible be small. It is usually through constructive Specifications, for example by the Attachment of the heating and / or blind pipes to end plates. This distance can usually be in the range between 20 to 40 mm.
  • solid waste A is fed or Feeder 2 with chute 3 and above a worm 4 driven by a motor 6 is and is arranged in a feed tube 7, centrally into a pyrolysis reactor or a smoldering chamber 8 brought in.
  • the smoldering chamber 8 is in the embodiment an internally heated, about its longitudinal axis 10 rotatable smoldering or pyrolysis drum which is one length can have from 15 to 30 m, which at 300 to 600 ° C works, largely under exclusion of oxygen is operated and in addition to volatile carbonization gas s produces a largely solid pyrolysis residue.
  • On the right or “hot” end is an inlet for heating gas h in the form of a dormant, sealed Heating gas inlet chamber 14 is provided, and at the left or “cold” end is an outlet for the heating gas h in the form of a stationary, sealed heating gas outlet chamber 16 arranged.
  • the longitudinal axis 10 of the Smoldering drum 8 is preferred to the horizontal inclined so that the outlet is on the right
  • the "hot" end is lower than the inlet shown on the left for waste A.
  • the smoldering drum 8 is preferably on slight negative pressure kept from the environment.
  • the pyrolysis drum 8 is on the output or discharge side via a rotating central discharge pipe 17 a discharge device 18 is connected downstream, the with a carbonization gas outlet 20 for the Outlet of the carbonization gas and with a pyrolysis residue outlet 22 for the release of the solid pyrolysis residue f is provided.
  • a discharge device 18 is connected downstream, the with a carbonization gas outlet 20 for the Outlet of the carbonization gas and with a pyrolysis residue outlet 22 for the release of the solid pyrolysis residue f is provided.
  • One at the smoldering gas discharge nozzle 20 is connected smoldering gas line with the burner of a high-temperature combustion chamber (not shown) connected.
  • the rotary movement of the smoldering drum 8 around it Longitudinal axis 10 is by a drive 24 in the form of a Gear causes, which is connected to a motor 26 is.
  • the drive means 24, 26 work for Example on a ring gear attached to the circumference of the Smoldering drum 8 is attached.
  • the bearings of the smoldering drum 8 are designated by 27.
  • heating tubes 12 each with one end on a first end plate 28 and with its other end to a second end plate 30 are attached.
  • the attachment to the end plates 28, 30 is such that there is preference for easy interchangeability the heating tubes 12 results.
  • the end of Heating tubes 12 each protrude 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 the heating tubes 12 are each perpendicular to the surface of the end plates 28, 30 aligned.
  • the individual Heating tubes 12 thermally and mechanically highly stressed are, and that the end plates 28, 30, also referred to as tube plates or drum tube sheets could be around the longitudinal axis 10 of the Turn smoldering drum 8 too.
  • the support points between the end plates 28, 30 X, Y to support the (otherwise possibly sagging) heating tubes 12 are provided.
  • the direction of transport of waste A is the first Support point X at about a third (1/31) and the second Support point Y is approximately two thirds (2/3 1) of the total length 1 of the smoldering drum 8.
  • the heating tubes 12 can be arranged in one configuration be as shown in Figure 2 and in Figure 3 is. Then there are a number of peripherally arranged Heating tubes 12b and a plurality along curved or straight lines of arranged heating pipes 12a for heating the more central waste. The curvature depends on the rotation of the Smoldering drum 8, indicated by an arrow 35 is.
  • the non-radial rows begin according to figures 2 and 3 each in the area of the inner wall 33. They are - and this is of particular importance - contrary to the Direction of rotation 35 curved (see Figure 2) or inclined (see Figure 3). This ensures that when rotating about the longitudinal axis 10 on the waste A collecting the heating pipes 12a, 12b early fall down and therefore no significant drop can reach. This eliminates the risk of damage effective from chunks contained in waste A. reduced.
  • an obtuse angle is in FIG. 3 ⁇ regarding the alignment of the individual rows entered to the tangent to the wall of the smoldering drum 8.
