Definitions

  • the invention relates to a tower structure of a preheating tower of a plant for thermal processing of minerals.
  • the invention also relates to a preheating tower with such a tower structure and a plurality of platforms, as well as a method for erecting the preheating tower.

  • a 6-stage preheater eight to nine platforms are usually provided, so that the building tower can reach a height of 160-170 m.
  • the construction time of the preheating tower is particularly time-consuming and usually takes 14 to 19 months.
  • the completion date of a cement plant is therefore essentially determined by the time required for erecting the preheating tower.
  • the preheating tower is made of concrete or steel, with the individual platforms being assembled one after the other from the bottom up and the machine equipment being lifted in with large heavy-duty cranes.
  • the profiles of the platforms are pulled up individually or in pre-assembled units and assembled to form the platforms. The same procedure is carried out with the components of the machine equipment.
  • the lining material required for certain components is transported to the respective platforms in the building tower, for example via a material lift and with the support of cable winches and large cranes, from where it is transported further manually and then installed.
  • a tower structure of a preheating tower of a plant for thermal processing of minerals comprising a plurality of support beams which extend vertically and parallel to one another and are connected to one another via cross beams, and a plurality of mounting positions each for attaching a platform to the tower structure.
  • the current method is time consuming and expensive due to the use of expensive jumbo cranes and many overhead hoists of steel and equipment into the building. These maneuvers are also associated with a non-negligible risk of accidents.
  • the invention is therefore based on the object of developing a preheating tower and a method for erecting such a preheating tower with which the construction and assembly time can be significantly reduced.
  • this object is achieved by a tower structure of a preheating tower having the features of independent device claim 1 and by a method for erecting a preheating tower having the features of independent method claim 7 9- .

  • a preheating tower preferably has a plurality of cyclones which are arranged one behind the other in, for example, five cyclone stages and separate solids and gas from these.
  • the cyclones are connected to each other via pipes for conducting raw meal and/or kiln exhaust gas.
  • raw meal such as mineral material such as limestone, passes through the individual cyclone stages from top to bottom and is preheated by the kiln exhaust gas in countercurrent.
  • the kiln exhaust gas enters the last or lowest cyclone stage in the preheater from below and flows from bottom to top through the individual cyclone stages, where it is cooled by the raw meal in the heat exchange.
  • a calciner is optionally arranged between the last and penultimate cyclone stage, which has a combustion device and ensures additional deacidification and calcination of the raw meal before it enters the kiln.
  • the tower structure is made of concrete and/or steel, for example, and preferably comprises only the structural elements of the building.
  • the support beams are preferably each formed in one piece, for example from steel and/or concrete, and in particular extend from the ground level to the top floor of the tower structure.

  • a changing cross-sectional profile of at least two, in particular adjacent, beams offers the advantage that the distance between two beams on the The height of the tower structure varies without causing a significant weakening of the load-bearing capacity or increasing the complexity of the structure.
  • At least two carrier beams each have a first and a second cross-sectional profile, the first cross-sectional profile being formed on the lower end region of the carrier beam.
  • the two carrier beams preferably have only two cross-sectional profiles, namely a lower and an upper cross-sectional profile.

  • the distance between the first and the second assembly position is approximately 1 m to 6 m, preferably 2 m to 5 m, in particular 4 m.
  • the absence of one of the crossbeams allows an assembled platform to be slid into the tower structure, although the height of the platform exceeds the floor height.
  • the invention also includes a preheating tower of a plant for thermal processing of minerals with a tower structure as described above and a plurality of platforms, each platform having a bottom plate and at least one cyclone attached thereto and wherein each platform is attached to a mounting position of the tower structure.

  • the tower structure can be erected with a height above the ground of at least 50 m, preferably at least 80 m and most preferably at least 100 m.
  • the assembly of the platform takes place at a level below the lowest assembly position, preferably at floor level.
  • the platform is assembled at ground level within the tower structure.
  • the main difference from previous practice when erecting a multi-storey building tower is that the individual platforms are set up at a level below their assembly position, in particular on the ground or on the assembly platforms provided on the ground, and then raised into their installation position in the tower structure, with the platforms are gradually introduced into the building structure, starting with an upper platform down to the lower platform. Since the platform is mainly set up on the ground, it is possible to set up several platforms at the same time. Since the construction of a platform takes more time than its installation, the assembly time is significantly reduced by working on several platforms in parallel.
  • the platforms are expediently equipped with machinery intended for the respective platform while they are still on the ground. They can also be fully or partially equipped with the necessary electrics and/or control technology. If individual machine parts are to be provided with a refractory lining, the platforms can be fully or partially equipped with a refractory lining required for the platform in question while they are still on the ground.

  • the platform is raised within the tower structure, preferably completely within the tower structure and in particular after the respective platform has been completely assembled within the tower structure.
  • the advantage of this is that the platform can be lifted up into its installation position within the building structure, which completely eliminates the need for a large number of gravity cranes placed outside the building tower for lifting the platforms.
  • the building structure itself therefore takes over the function of the cranes. This measure can also significantly shorten the assembly time.
  • occupational safety is significantly improved, as the fully assembled platform on the ground only has to be pushed into the building structure and then lifted straight up into its installation position.
  • the assembly of at least one of the platforms comprises the mounting of at least one cyclone on a floor structure.
  • the tower structure is achieved by assembling profiles made of steel or concrete, so that the tower structure has a wider lateral insertion opening below the second assembly position, preferably below the first or second assembly position, than above the first or second assembly position.
