Definitions

  • the invention relates to a device for drying and preheating coking coal in the fluidized bed by means of indirect heat exchange with a heating medium, which consists of a plurality of cascades cascading through the coking coal one after the other, each with vertically arranged heating pipes and an inflow floor at its lower end for producing the fluidized bed, the inflow floor consisting of horizontal tubes provided with outlet openings for the fluidized bed medium and arranged next to one another.
  • a device for drying and preheating coking coal in the fluidized bed is already known from DE-AS 23 42 154, steam being used both as a heating medium and as a fluidized bed medium.
  • the drying and preheating of the coal to a temperature of over 150 ° C takes place here in one stage, so that a very intensive heat supply is required, which experience has shown to have an adverse effect on the quality of the coal. It is possible that the coal will cake or cake on the heating pipes. Local overheating of the carbon particles can also take place, as a result of which changes in the coking properties can occur.
  • a device which consists of a plurality of cascades through which the coking coal passes one after the other, each having vertically arranged heating pipes and an inflow base at their lower end for producing the fluidized bed.
  • an inflow floor for producing a fluidized bed which consists of horizontal tubes arranged next to one another and provided with outlet openings for the fluidized bed medium.
  • the invention has now set itself the task of designing the inflow floor in a device of the type mentioned in such a way that an even more intensive and uniform fluidization of the coal in the bottom region of the cascades is achieved.
  • parts of the tubes of the inflow floor are guided upwards on the inner wall of the cascades and are also provided there with outlet openings for the fluidized bed medium.
  • a further advantageous embodiment of the generic device for drying and preheating coking coal is that the heating pipes in the individual cascades are combined to form a plurality of bundles arranged one above the other with separate feed and discharge lines for the heating medium. This measure significantly improves the space utilization of the tapering downwards, i.e. conical cascades than achieved in a single-stage heating tube arrangement.
  • the device for drying and preheating the coking coal has three cascades 1 and 111 arranged one above the other.
  • Each of these cascades tapers downwards in the shape of a truncated pyramid and in the present case contains three tube bundles A, B and C lying one above the other (FIG. 3).
  • These bundles of vertical heating pipes each have a branch line 1 connection to the main feed line 2 for the heating medium and a branch line 3 connection to the main exhaust line 4 of the heating medium.
  • the coal to be treated is first introduced into the uppermost cascade I, which it traverses from top to bottom and which it leaves through line 10. Via the cellular wheel sluice 11 and the line 12 connected to it, it then arrives in the middle cascade 11 and from this in turn through the line 13, the cellular wheel sluice 14 and the line 15 into the bottom cascade 111 .
  • the coal is subjected to a gradual heat treatment, in which it essentially pre-dries in the top cascade is, while further drying and preheating takes place in the middle cascade and finally the desired final temperature of the coal is set in the lowest cascade. This gradual application of heat ensures extremely gentle treatment of the coal.
  • a cascade with the bundles A, B and C vertical heating pipes is shown on a larger scale.
  • branch lines 1 for the supply of the heating medium to the individual bundles.
  • These branch lines are connected to the horizontal distribution lines 17, which in turn feed the vertical heating tubes 18.
  • the latter have at their lower end connection to the horizontal manifolds 19 and this to the already mentioned branch lines 3 of the main exhaust line 4.
  • the vertical arrangement of the heating pipes is particularly advantageous when - as mentioned - saturated steam is used as the heating medium, since in this case a uniform condensation of the saturated steam is guaranteed.
  • the inflow floor consists of a number of horizontal tubes arranged side by side, which are provided with outlet openings (not shown) for the fluidized bed medium. These outlet openings can have a diameter of 5 mm, for example, and are preferably attached to the underside of the tubes. This prevents coal from entering the pipe if the supply of the fluidized bed medium is interrupted.
  • These horizontal pipes are connected to the branch line 6 by the connecting lines 21.
  • the tubes 20 as tube parts 20 a and 20 b are guided upwards along the inner wall of the cascade.
  • These tube parts are also provided with outlet openings for the fluidized bed medium, so that the walls cause additional fluidization of the coal.
