Definitions

  • the present invention relates to the field of metallurgical plants, specifically the iron industry for cooling hot bulk material.
  • the disassembly and subsequent assembly of this gas-tight cover is very expensive.
  • the tightness of the cover must be restored each time, so as not to suck in unwanted gases or solids from the outside, which would additionally increase the amount of gas to be dedusted.
  • the CN202372014-U discloses a circular cooling device with a flue gas cover.
  • the JP2013002782 shows a sintering plant with a sintered ore cooling device.
  • the object of the present invention is to provide a device which on the one hand reduces the dust emissions and on the other hand enables maintenance measures on the radiator easily and in a short time.
  • This object is achieved by the radiator mentioned above in that the second region has a boundary consisting of a stationary first wall and a stationary second wall, and this boundary extends to at least a portion of the second area, preferably over the entire second area, wherein the first wall and the second wall are suspended from a support structure, and the first wall rests on the first radiator wall or from it is separated by a gap, and the second wall rests on the second radiator wall or is separated from it by a gap.
  • the resting on the first radiator wall or separated by a gap first wall, and resting on the second radiator wall or separated by a gap second wall prevent transport of - located on the grate surface - dust by the cooling gas or by external wind influence.
  • Under rest or separated by a gap in this context means that the movement of the radiator is not hindered by excessive friction between the walls and a possible gap should be made as small as possible - to prevent the escape of dust particles.
  • Due to the exit velocity of the cooling gas from the bulk material located on the grate surface particles are carried along by the cooling gas. Due to the dedusting at the feed point, a large part of the dust particles - which are smaller than 150 ⁇ m in size - are removed.
  • the cooler according to the invention was surprisingly found that dust particles are larger than 150 ⁇ m and which ascend through the cooling air for the most part again settle on the grate surface or on the bulk material thereon.
  • the first wall and the second wall prevent the entrained particles are not removed by external wind influence or the cooling gas.
  • external wind influence is a crosswind that acts on the radiator transversely to the direction of movement.
  • it can also act partially in the direction of movement and - due to the round shape of the cooler - remove the particles beyond the surface of the grate.
  • the height of the side walls depends on the exit velocity of the cooling gas from the bulk material.
  • the height of the boundary is the height which is measured from the upper edge of the bulk material to the upper edge of the first wall or second wall - preferably the first wall and the second wall are the same height - is measured.
  • the first wall and the second wall are arranged stationary and the cooler is designed to be movable. Movable means that it is a continuous promotion that can take place in a circle or even straight.
  • a support structure is provided at the first wall and the second wall are hung up.
  • This support structure is designed so that a rapid disassembly of the boundary can take place, it does not need to be restored as shown in the prior art, the gas-tightness.
  • the limitation greatly reduces the amount of diffusely emitted dust.
  • the boundary should extend over a partial area, preferably over the entire second area.
  • the first cover, the third cover and the boundary In order to allow maintenance on the cooler without dismantling the boundary, the sum total is covered by the first cover, the third cover and the boundary between 80% and 95% of the grate area. To achieve the greatest effect for the reduction of dust emissions, the first cover, third cover and the boundary encompass the entire grate area.
  • annular cooler is that the boundary of a height which is measured between the upper edge of the bulk material and upper edge of the first wall or second wall of at least 1m, preferably 1.5m, more preferably 2.0m very particularly preferably 2.5m having.
  • the height between the top edge of the bulk material and the top edge of the first wall or second wall affects the result of reducing dust emissions.
  • the boundary should have a minimum height of 1m. This sets the desired effect that the dust particles settle back on the grate surface. At a distance of more than 2.5 m, no noticeably higher reduction of dust emissions is noticeable.
  • the boundary additionally has a perforated plate which is located between the first wall and the second wall.
  • the perforated plate is disposed between the first wall and the second wall so as to face the grate surface, preferably substantially parallel to the grate surface.
  • angular deviations of up to ⁇ 10 ° are meant.
  • the perforated plate further improves the reduction of dust emissions.
  • the perforated plate ensures that dust particles - which would be carried over the boundary - are retained and, on the other hand, that the existing cooling gas can emerge uniformly over the entire grate surface.
  • perforated plate is a plate understood - for example, from a steel sheet - which holes, other cutouts or openings have that allow the cooling gas can flow through.
  • a perforated plate is a grate. The perforated plate lies between the first wall and the second wall.
  • a further advantageous embodiment of the cooler is that the boundary consists of individual segments.
  • the radiator must be serviced at regular intervals. In this case, individual components of the radiator are changed.
  • the Boundary of several segments which are mounted by an easily detachable connection - such as a screw or bolt connection.
  • the individual segments each consist of a first wall and second wall corresponding to the segment size.
  • a segment may additionally have a perforated plate.
  • the respective segments of the boundary can either be lifted off as a whole after releasing the connection between the segment and the supporting structure, or the first wall and / or second wall and / or the perforated plate of the segment are removed.
  • the segments can have different sizes.
  • One possible variant is that the boundary consists of only two segments, a large segment that is removed only in exceptional cases and a smaller one which is removed for maintenance purposes. To minimize manufacturing effort, a preferred solution is to make all segments the same size.
  • a temperature-resistant seal is attached to the transition from the first cooler wall to the first wall and the transition from the second cooler wall to the second wall.
  • a temperature-resistant seal may for example consist of a fabric or be designed as a brush seal. Under temperature resistance is understood in this context, a temperature up to 600 ° C.
  • a further advantageous embodiment is that the perforated plate perforations of up to 70%, preferably up to 60%, most preferably of up to 50% of the total area - the perforated plate - has. It has been found that perforations in a range of 50% to 70% provide the best results in terms of reducing dust emissions and refrigerant gas leakage.
  • the perforated plate is made of expanded metal.
  • An expanded metal has excellent properties in terms of openings, strength and weight.
  • the dust emissions are reduced to a minimum and on the other hand, the cooling gas can emerge uniformly over the entire surface.
  • the lower weight has a positive effect on the supporting structure - as it can be designed for lower loads.
  • a use of the cooler provides that the hot bulk material is iron ore sinter or manganese ore sinter.
  • the coolers according to the invention are frequently used for cooling iron ore sinter and manganese ore sinter.
  • the cooler is designed as an annular radiator.
  • An annular radiator can be made more compact to hold the same amount of bulk material. Another great advantage is that in an annular cooler almost the entire grate surface is loaded with bulk material and this can thus be cooled. For a straight cooler, the grate area moving from the point of removal to the point of loading is not loaded. Thus, only about half of the grate surface can always be used.
  • An annular radiator requires only half the grate area compared to a straight radiator - bulk material to be cooled for the same amount.
  • the limitation is particularly advantageous since the removal of the particles by wind influence can always occur from all directions. Through the round embodiment, the problem of shipping by wind influence is always given. There is no clear wind direction that is particularly critical or particularly uncritical.
  • annular radiator provides that the individual segments have an angle of at least 10 ° and a maximum of 20 °.
  • the size is chosen so that maintenance of the annular radiator can be done and the limitation can be removed with reasonable effort and in a short time.
  • Fig. 1 shows a plan view of an annular radiator 1. It is theivitystelle 2 - which in the first area. 4 is - as well as the cover located above the first area 4 7 shown.
  • the first region 4 comprises a region which is characterized by the angle ⁇ 1 .
  • the first region 4 is followed by the second region 5 in the direction of rotation, which is shown by the arrow.
  • the second region 5 has no cover.
  • the annular radiator 1 has a grate surface 16 - which is bounded by a first radiator wall 10 and a second radiator wall 9 - which can accommodate hot bulk material.
  • the size of the second region 5 is represented by the angle ⁇ 2 .
  • a third area 6 lies between the other two areas 4 and 5, and in this third area 6 there is also the discharge point 3 and a third cover 8.
  • the size of the third area 6 is represented by the angle ⁇ 3 .
  • the first radiator wall 10 corresponds to a radiator inner wall
  • the second radiator wall 9 corresponds to a radiator outer wall.
  • Fig. 2 shows a side view of a straight line radiator 1. It is theIFFstelle 2 - which is located in the first region 4 - and the cover located above the first region 4 7 is shown.
  • the second region 5 follows the first region 4 in the direction of the movement direction, which is shown by the arrow.
  • the second region 5 has no cover.
  • the straight radiator 1 has a grate surface 16 - which is bounded by a first radiator wall 10 and a second radiator wall 9 - which can accommodate hot bulk material.
  • a third area 6 then follows the second area 5 and in this third area 6 there is also the discharge point 3 and a third cover 8.
