Definitions

  • the invention relates to a clinker cooler with a dedusting device in a method for producing cement, the hot clinker falling at temperatures of 1150 to 1300 ° C. on an air-permeable conveyor belt and being cooled with cooling air conducted through the TransportLand, the cooling air then passed through a dedusting device and up to a residual dust content of about 30 to 100 mg / Nm 3 is dedusted and a solid transport device receiving the cooled clinker is arranged under the clinker cooler.
  • the clinker cooler is a known part of a plant for cement production, and the dedusting device for the cooling air coming from the clinker cooler is also known. Since the dedusting device has a large volume and weight due to the necessary performance, it is customary in known systems to place the dedusting device next to the clinker cooler. This arrangement of clinker cooler and dedusting device leads to considerable space requirements, to a relatively long cooling air line from the clinker cooler to the dedusting device and for the latter to a separate dust transport device.
  • the invention has for its object to provide a combination of clinker cooler and dedusting device, the space requirement is small and which reduces the system and operating costs. According to the invention, this is done in that the dedusting device is arranged above the clinker cooler and the discharge line or discharge lines for dust separated in the dedusting device opens or opens directly above the solids transport device.
  • the arrangement according to the invention makes it possible to supply the dust-containing cooling air from the clinker cooler with a short line to the dedusting device, and at the same time the solids transport device which necessarily belongs to the clinker cooler can also transport the dust accumulating in the dedusting device. Another advantage is the small space requirement of the system combination.
  • the dedusting device expediently contains at least one cyclone with a downstream fine dedusting device.
  • the fine dedusting device there are several options for the fine dedusting device, in particular the use of a granulate filter, but the various types of fabric filters are also suitable.
  • Granulate filters in which the dust is removed from the air passed through the layer by a layer of solid granulate, are known per se and e.g. described in German Patent 27 19 544 and German Offenlegungsschrift 29 51 877. These filters have the advantage that, on the one hand, they ensure good dust separation and, on the other hand, the dust-laden granulate can be cleaned and reused continuously and easily.
  • An embodiment of the invention is shown in the drawing. It shows a schematic representation of a longitudinal section through the clinker cooler with associated dedusting device.
  • the hot clinker comes with temperatures of 1150 to 1300 ° C, for example, from a rotary tube, not shown, and passes through the inlet 1 of the clinker cooler 2 to an inclined conveyor belt 3.
  • the conveyor belt 3 consists in a known manner of air-permeable metal members.
  • Cooling air is first fed from the blower 4 to an invisible manifold, from which the cooling air enters the clinker cooler below the conveyor belt 3 through numerous openings 5.
  • the cooling air flows upwards through the conveyor belt 3 and the clinker layer thereon, which is not shown.
  • Dust-containing cooling air leaves the clinker cooler through the exhaust pipe 6.
  • Cooled clinker with a temperature of approximately 70-120 ° C. falls at the lower end of the conveyor belt 3 in the direction of arrow 7 through an outlet 8 onto an endless transport device 9.
  • This transport device 9 the is only partially shown in the drawing, for example in a known manner be designed as a drag chain. Solids that fall down in the clinker cooler 2 also reach the transport device 9 through a plurality of discharge lines 12.
  • the solid-containing cooling air in the exhaust pipe 6 is fed to a multi-part dedusting device, which is shown only partially and in simplified form in the drawing.
  • the dedusting device can e.g. consist of several parallel dedusting elements 13, of which the drawing shows an element.
  • This element consists of a cyclone 14 with a downstream granulate filter 15.
  • the dust-containing cooling air is first roughly dedusted in the cyclone 14, the air flowing helically around a tube 16 and reaching the granulate filter 15 through the lower end of the tube.
  • the flow path of the air out of the tube 16 into the granulate filter 15 is indicated by the arrows 17a and 17b.
  • the granulate filter 15 has an essentially cylindrical granulate layer 18, which is located between air-permeable walls.
  • the dust-containing air flows through the granulate layer 18 from the outside inwards, as is indicated by the arrows 19a and 19b.
  • the fine dust fraction is retained in the granulate layer and the exhaust air cleaned to a residual dust content of 30 to 100 mg / Nm 3 is led through line 22 to the common exhaust air chimney.
  • the filter is separated from the line 22 in a manner not shown, and the granules are conveyed pneumatically through a central line 20 from bottom to top to a collecting container 21 and through which purge air flows against the normal gas direction, the lighter traffic jam from the heavier granules.
  • the conveying gas used for the line 20, usually air, is fed into the exhaust pipe 6.
  • the dust falls through the pipe 16 into the solid line 26.
  • Dust-free granulate collects in the container 21 and flows back to the granule layer 18 via several downpipes 23. Dust-free air leaves the granule filter in the clean gas line 22, which usually leads to a collecting line with a fan, which is not shown in the drawing for simplification.
  • the solids deposited in the cyclone 14 and during the cleaning process of the granulate layer 18 fall into a line 26 and pass through this line to the transport device 9.
  • the line 26 runs outside the clinker cooler 2, which is indicated by the line line shown in broken lines. If several dedusting elements 13 are connected in parallel, as is customary, all solid lines 26 of these elements discharge their solids to the transport device 9, so that an additional transport device is unnecessary.
