Definitions
- the invention relates to a grate block for a system for thermal treatment of waste according to the generic term of claim 1.
- the present invention is based on the object to form an economically more advantageous grate block.
- a grate block comprising a substantially rectangular one Body defining the longitudinal direction with a cast, meandering pipe, with a partial section of the tube in the longitudinal direction laterally in Grate block is arranged.
- a fluid is used as the coolant, preferably water used to cool the Rust block flows through the pipe.
- the arrangement of a section laterally in the Rust block in the longitudinal direction of the pipe shows the Advantage on that a large over the side surfaces Amount of heat can be dissipated.
- An advantage of the invention is to see that the side walls or the lateral limits of the grate with the Cool the grate block according to the invention in a simple manner to let.
- the longitudinal alignment of the pipes also prevents largely differentiated cooling in the longitudinal direction of the grate block, which has the advantage that in Longitudinal no major temperature differences occur.
- the grate block according to the invention has the advantage that this effect can be compensated for by two Grate blocks with their side faces side by side be arranged, the one side surface the light higher temperature and the other side face the slightly has lower temperature, so that the existing Temperature difference through a heat exchange over the adjacent side surfaces is reduced.
- this is Pipe with respect to the longitudinal direction of the grate block trending plane of symmetry trending symmetrically arranged. This has the advantage that it is used Equipping an entire grate with just one Embodiment of rust blocks is required.
- grate block according to the invention Another advantage of the grate block according to the invention can be seen in the fact that the inserted tube to achieve the required cooling capacity relatively fewer curvatures needs, which is why the design of the shape of the tube is inexpensive to manufacture.
- This tube is called Semi-finished and the ready-made tube in one Mold inserted for a grate block unit and the Rust block cast in a known manner.
- the grate block 1a shows a longitudinal section through a grate block 1 in the longitudinal direction L.
- the grate block 1 is as a casting made with a cast tube 16.
- the grate block has an upper wall 23 which has a usable area 33 trains.
- the upper wall 23 opens on the left-hand side in a rear wall 21 and in a hook 22.
- the upper wall 23 opens into a corner 25 and then into the front wall 24, which has a foot 26 below with a bearing surface 26a.
- the rear wall 21 and the front Wall 24 is closed by a side wall 29.
- the pipe 16 has a water supply nozzle 30 and rises then up to the corner between the top wall 23 and the side wall 29 and runs there in one Section 16a along the corner in the longitudinal direction L to to the corner 25. Then the pipe 16 drops to the level of 26 foot and then runs perpendicular to Viewing plane through the 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 extends over a length L5 along the side wall 29.
- the grate block 1 has one entire length L4 and the foot a support surface 26a of length L3. In the front wall 24 there is also one Air outlet opening 47 is arranged.
- FIG. 1b shows a further embodiment of a Rust block 1 which is very similar to that in Fig. 1a illustrated example is designed.
- the pipe 16 initially runs approximately perpendicular to the nozzle 30 Longitudinal direction L, then has an arc of 90 degrees, and in section 16a again runs in the corner between the top 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 one fifth of the total length L4 of the grate block 1 is.
- the section 16a extends about over two thirds of the length L4, in Fig. 1b 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. 1a, an upper wall 23, which laterally through a left side wall 29a and a right one Side wall 29b is bounded at the front by the front wall 24 and behind 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 to Viewing plane running symmetry plane S on.
- the Tube 16 and the nozzle 30, 43 are symmetrical to the plane S arranged in the grate block 1.
- the sockets 30, 43 are protruding beyond the rear wall 21 and thus simple arranged accessible.
- the sections 16 a of the tube 16 run freely in a first section and open against the front wall 24 into the casting.
- the one in essentially in the longitudinal direction L section 16a subsequently has a curved one Section 16b opens into another Sub-section 16c extending in the longitudinal direction L, thereupon again in 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 one Section 16f and opens into the transverse to Longitudinal direction L in the foot 26 extending portion 16g.
- the tube 16 has a slightly meandering shape, over wide However, stretch the shape running in the longitudinal direction L. This tube 16 has relatively few points of curvature, which is why it is inexpensive to manufacture.
- the sidewalls 29a, 29b are through the extending in the longitudinal direction L. Section 16e cooled very well. Will the cooling water initiated for example by the nozzle 30, so the right side wall 29b experiences a slightly stronger one Cooling as the side wall 29a since the water until it has reached section 16e of side wall 29a, has already warmed up. This is usually minor Temperature difference from the left and right side wall 29a, 29b is partly due to the thermal conductivity of the Cast part compensated.
- grate element 3 is a grate element 3 as part of a grate for a plant for the thermal treatment of waste such as waste shown.
- Several grate blocks 1 arranged side by side form the width of the grate.
- the grate element 3 has in the illustrated Execution example nine in the longitudinal direction L in a row arranged rows 4.5 of rust blocks 1, wherein each a fixed realm 4 of a moving row 5 follows. All grate blocks 1 are at one end by one Block holder tube 7 pivotally mounted. The block holder tube 7 the fixed grate blocks 1 is on a stationary Console 8 attached, while the block holder tube 7 of movable grate blocks 1 on a in the longitudinal direction L linear movable console 9 is attached. All movable consoles 9 are on a in the longitudinal direction L back and forth movable grate car attached, which over Rolling is mounted on a carrier of the grate element 3.
- This movement in the longitudinal direction L essentially causes a movement of the movable row 5 of grate blocks 1 in Direction of movement L1, with all grate blocks also one slight pivoting movement around the respective block holding tube 7 To run.
- the formed by the grate blocks 1 The conveyor line is laterally through a side termination 15 or a side wall 15 limited.
- Rust block 1 can be seen in that only one Embodiment suffices to meet all requirements Cooling is sufficient, both the cooling of the grate block as well as the cooling of the side end 15. Also the sockets 30, 43 are always arranged in the same place, which significantly simplifies the supply of the fluid.
- 3a shows a perspective bottom view of a another embodiment of a grate block 1, wherein the meaning of the reference numerals with those of the figure 2a, 2b coincides.
- This grate block 1 is also symmetrical to one indicated in FIG. 3b Plane of symmetry S designed.
- 3b shows the course of the pipe 16 cast in the grate block 1 according to FIG. 3a.
- the water is supplied via the nozzle 30 and flows then over the sections 16a, 16b, 16i, 16d, 16k, 16h to in the longitudinal direction L and along the side wall 29b extending portion 16e, and then over the Section 16f perpendicular to the longitudinal direction L., extending section 16g, and then over the symmetrically designed course of the tube 16 back for fitting 43.
- the tube 16 could also be cast in the grate block 1 in this way be that the tube 16 symmetrical to the plane of symmetry S runs without the tube 16 but one on the Side wall 29a, 29b extending in the longitudinal direction L. Has section 16e. This would cool the Sidewall 29a, 29b reduced, the other advantages of However, the arrangement according to the invention would be obtained stay.
- the grate block is preferably cooled such that on the one hand, it is as warm as possible to keep the To remove little heat from surface 33 on the other hand, however, is so cool that it is made of cast iron existing rust block no excessive wear from the experiences 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 There are sections that have a flow for the Train fluid.
- grate block 1 several, for example, two separate pipes 16 can be cast in, where both tubes have two sockets 30, 43 and thus be supplied separately with a fluid such as water can.
- These two tubes 16 could, for example running symmetrically to the plane of symmetry S in grate block 1 be arranged.
