Definitions

  • the invention relates to a grate block for a Plant for the thermal treatment of waste according to the preamble of claim 1.
  • EP 0 844 438 A2 is a Grate known for a furnace, which one A plurality of grate blocks provided with cooling channels having. These known, having a longitudinal direction Grate blocks are perpendicular to the longitudinal direction of the grate cooling channels, which are meandering are arranged, and in the longitudinal direction a different allow strong cooling.
  • a disadvantage of these known rust blocks is the fact that for a grate having a A plurality of grate blocks arranged side by side differently designed grate blocks required are. Furthermore, the side walls of the grate are bad cooled. In addition, the design is meandering Cooling channels relatively expensive and accordingly expensive.
  • the object of the present invention is to achieve this based on an economically more advantageous grate block to build.
  • Rohrs has the advantage that over the side surfaces a large amount of heat can be dissipated.
  • An advantage of Invention can be seen in the fact that the side walls or the lateral boundaries of the grate with the rust block according to the invention in a simple manner let cool.
  • the longitudinal alignment of the pipes prevented also largely differentiated cooling in Longitudinal direction of the grate block, which has the advantage that there are no major temperature differences in the longitudinal direction occur.
  • the grate block according to the invention has the advantage that this effect can be compensated for is that two grate blocks with their side faces be arranged side by side, the one side face the slightly higher temperature and the other side surface which has a slightly lower temperature, so the existing temperature difference through a heat exchange over the adjacent side surfaces is reduced.
  • a particularly advantageous embodiment is the pipe with respect to a in the longitudinal direction of the Grate block running symmetry plane symmetrical arranged progressively. This has the advantage that it only has to be used to load an entire grate requires a single embodiment of rust blocks.
  • Rust block can be seen in that the inserted Relative tube to achieve the required cooling capacity requires fewer curvatures, which is why the design the shape of the tube is inexpensive to manufacture.
  • This tube is prefabricated as a semi-finished product and that ready-to-use tube in a mold for a grate block unit inserted and the grate block on known Poured way.
  • Fig. 1a shows a longitudinal section through a Grate block 1 in the longitudinal direction L.
  • the grate block 1 is as a casting with a cast tube 16 made.
  • the grate block has an upper wall 23 which forms a usable area 33. Merges on the left the upper wall 23 into a rear wall 21 as well into a hook 22. On the right side the upper wall 23 in a corner 25 and then in the front Wall 24, which has a foot 26 with a bottom Forms bearing surface 26a.
  • Towards the back is the upper one Wall 23, the rear wall 21 and the front Wall 24 is closed by a side wall 29.
  • the tube 16 has a water supply connection 30 and then climbs to the corner between the top wall 23 and the side wall 29 and runs there in a section 16a along the corner in Longitudinal direction L to the corner 25. Then the pipe falls 16 from to the height of the foot 26 and then runs perpendicular to the viewing plane through foot 26.
  • the tube 16 runs over a length L2 as a section 16a in the longitudinal direction L along the corner.
  • the Tube 16 runs along a length L5 along the side wall 29.
  • the grate block 1 has an entire length L4 on and the foot a bearing surface 26a of length L3. There is also an air outlet opening in the front wall 24 47 arranged.
  • Fig. 1 b shows a further embodiment a grate block 1 which is very similar to that in Fig. 1a example is designed.
  • the pipe 16 initially runs approximately vertically after the nozzle 30 to the longitudinal direction L, then has an arc of 90 Degrees, and runs in section 16a again in the corner between upper wall 23 and side wall 29 in the longitudinal direction L.
  • the section 16a extends over a length L2 in the longitudinal direction L, the length L2 advantageously at least a fifth of the total length L4 of the grate block 1.
  • Fig. 1 a extends the section 16a is approximately over two thirds of the length L4, in Fig. 1 b about four fifths of the length L4.
  • FIG. 2a shows another in a bottom view Embodiment of a grate block 1.
  • This in essentially rectangular grate block 1 defines a longitudinal direction L and points, as already in Fig. 1 a shown, an upper wall 23, which laterally through a left side wall 29a and a right one Side wall 29b is bounded by the front at the front Wall 24 and back through the rear wall 21.
  • On the rear wall 21, two hooks 22 are arranged.
  • the Grate block 1 has one in the longitudinal direction L and perpendicular plane of symmetry extending to the viewing plane S on.
  • the tube 16 and the nozzle 30, 43 are symmetrical arranged to level S extending in grate block 1.
  • the sockets 30, 43 are over the rear wall 21 above and thus easily accessible.
  • the sections 16a of the tube 16 run in a first section free and open against the front Wall 24 into the casting.
  • the essentially has in the longitudinal direction L portion 16a then a curved section 16b, opens into another in the longitudinal direction L-running section 16c, then again into a curved section 16d, which opens into section 16e.
  • FIG. 2b shows a sectional view along the line A-A the course of the section 16e, which in the corner of top wall 23 and right side wall 29b runs. Then the pipe sinks in a section 16f and opens into the transverse to Longitudinal direction L in the foot portion 26 extending 16g.
  • the tube 16 has a slightly meandering, over long distances, however, running in the longitudinal direction L. Shape up. This tube 16 has relatively few Curvature points on, which is why it can be manufactured inexpensively is.
  • the side walls 29a, 29b are covered by the in Longitudinal direction L section 16e very well cooled. Is the cooling water, for example, by the Stubs 30 initiated, the right side wall experiences 29b a slightly stronger cooling than the side wall 29a, since the water reaches the subsection 16e the side wall 29a has already reached. This is usually a slight temperature difference from the left and right side walls 29a, 29b partly due to the thermal conductivity of the casting compensated.
  • left and / or right of the grate block 1 shown another grate block 1 arranged so that the side walls 29a, 29b are opposite and thus their slightly different Temperatures is additionally compensated so that a relatively uniform temperature distribution arises.
  • grate element 3 is a grate element 3 as part of a Grate for a thermal treatment plant represented by waste as garbage.
  • Several grate blocks 1 arranged side by side form the width of the grate.
  • the grate element 3 has in the illustrated embodiment nine in the longitudinal direction L. arranged rows 4.5 of rust blocks 1, wherein each a fixed realm 4 a movable Row 5 follows. All grate blocks 1 are on one End pivotally mounted around a block holder tube 7. The block holder tube 7 of the fixed grate blocks 1 is attached to a fixed console 8, whereas that Block holding tube 7 of the movable grate blocks 1 on one in the longitudinal direction L linearly movable bracket 9 attached is. All movable consoles 9 are in one Longitudinal direction L reciprocating grate car attached, which via rollers on a carrier of the Grate element 3 is mounted.
  • This movement in Longitudinal direction L essentially causes a movement the movable row 5 of grate blocks 1 in the direction of movement L1, with all grate blocks also one slight swiveling movement around the respective block holder tube 7 run.
  • the formed by the grate blocks 1 Conveyor track is laterally through a side end 15 or a side wall 15 limited.
  • a major advantage of the inventive Rust block 1 can be seen in that only one Embodiment meets all requirements regarding Cooling sufficient, both the cooling of the Rust block as well as the cooling of the side end 15.
  • the sockets 30, 43 are always on the same Place arranged what is the supply of the fluid much simplified.
  • 3a shows a perspective bottom view a further embodiment of a rust block 1, the meaning of the reference numerals with those 2a, 2b corresponds.
  • This one too Grate block 1 is symmetrical to one shown in FIG. 3b Plane of symmetry S designed.
  • 3b shows the course of the cast in the grate block 1 according to Fig. 3a Rohres 16.
  • the water is over the nozzle 30 fed, and then flows over the sections 16a, 16b, 16i, 16d, 16k, 16h for the longitudinal direction L and section extending along the side wall 29b 16e, and then over the section 16f to the section running perpendicular to the longitudinal direction L. 16g, and then over the symmetrical designed course of the tube 16 back to the nozzle 43rd
  • the grate block is preferably cooled in such a way that it is as warm as possible to prevent garbage lying on the surface 33 to little heat withdraw, but on the other hand is so cool that the Cast rust block not excessive Undergoes wear due to the high temperature.
  • the cast pipe 16 is made of metal or a metal alloy, for example made of cast iron.
  • the tube 16 can be formed in one piece, or from several connected sections exist, which form a flow for the fluid.
  • In the grate block 1 could also be several, for example two separate ones Pipes 16 can be cast in, both pipes two each Have nozzle 30.43 and thus separated with one Fluid such as water can be supplied. These two Pipes 16 are symmetrical to Plane of symmetry S arranged in the grate block 1 his.
