Definitions

  • the invention relates to a method and a device for producing active molded coke as granules on the basis of pretreated hard coal, in which preformed granules are conveyed through different treatment zones of a shaft and heated in these zones by gases or vapors fed in and out laterally, heated. with steam or C0 ? -Gas or a mixture of water vapor and CO -Gas activated and aftertreated and cooled.
  • the material to be treated which is conveyed through the shaft, is deflected several times in opposite directions in the form of a column of material in order to achieve a larger reaction area and an effective mixing of the reactants, and the gases or vapors flow through it in the direction transverse to the column of material.
  • the material to be treated is passed through sleeve-shaped internals which pass centrally over the shaft from top to bottom and the column of material is acted upon and flowed through by treatment gases introduced from the side.
  • the invention is based on the object of developing a method of the type described in the introduction in such a way that the aforementioned disadvantages are avoided and in all treatment zones a uniform application or flow around all the granules with very favorable fluid-mechanical effectiveness, i.e. a favorable ratio of transmitted power to applied mechanical power is achieved.
  • the method mentioned at the outset is characterized by the features mentioned in the characterizing part of claim 1.
  • the shaping of the granules with a uniform size results in approximately equal gap spaces in the individual piles, which are of particular importance for the gases or vapors to flow through the piles in the individual treatment zones.
  • the flat piles with the same layer thickness over their cross-section there is approximately the same flow resistance at all points across the cross-sectional area of the piling, so that even flow through the piles is achieved with a uniform flow.
  • the uniform inflow of the individual piles in the area of the introduction of the gases or vapors into the shaft is ensured by the supply of the gases or -. -
  • Vapors reached in the free spaces between adjacent heaps When several gases are stacked on top of one another through the gases or vapors, any irregularities in the flow, i.e. locally different flow velocities or local differences in the pressure of the gases or vapors emerging from the previous heap are compensated again, so that these irregularities cannot have a disadvantageous effect over the entire flow path of the gases until they are removed.
  • the piles maintain a constant layer thickness as they travel through the treatment zones.
  • the controlled moving out of at least some of the grate bars from the grate level results in a dissolution of the pile located on these grate bars, wherein the control of the movement of the grate bars mentioned achieves the desired uniform trickle flow and on the next one Rust can in turn form a pile with the same layer thickness over the cross-section.
  • the most favorable movement sequence of the grate bars can be determined by appropriate previous trickle tests and the control for the movement of the grate bars can then be set accordingly.
  • the movable grate bars also simultaneously dissolve any good bridges that may have arisen.
  • a time-controlled lowering or a time-controlled lifting of the movable grate bars can be provided.
  • the carbonization gas is therefore directed through the piles in the opposite direction to the conveying direction of the granules when they are transferred from rust to rust.
  • the smoldering zone can comprise several heaps through which the smoldering gas flows in succession.
  • the carbonization gas usually has a temperature of around .00 ° C.
  • the countercurrent flow of the carbonization gas through the heaps allows the granules in the pile to be reached or slightly exceeded when the flow rate of the gases is set, so that the granules in the carbonization zone are caked or glued together by adjusting the flow rate of the carbonization gas accordingly largely prevented can be.
  • the flow rate based on the free cross-section of the shaft, can be up to 5 m / sec. be.
  • the piles are partially and locally shielded from flowing through the smoldering gases and flowed through in the respective other areas until the loosening point is reached or exceeded.
  • an alternating partial movement of the granules in the pile or else a partial shifting from the areas through which the flow is flowing to the areas through which no flow occurs can be achieved, with the return of the previously shifted granules always being able to be achieved by the local change in the partial flow.
  • the piles in the heating, activation and post-treatment zone are flowed through in one direction during one or a few dwell times and in the opposite direction during other dwell times, since this results in Heat gradients in the piles is reduced.
  • the heaps in the cooling zone are sprayed with water and the water vapor generated in the cooling zone is fed to the heaps of at least one of the preceding treatment zones.
  • the water vapor generated in the cooling zone is fed to the heaps of at least one of the preceding treatment zones.
  • the device for supplying and evenly distributing the pre-dosed piles of egg nem in an entry lock over the shaft cross-section has a movable box with a grate as the bottom, which corresponds to the rust in the shaft in its design and can be operated in the same way.

  • Such dividing walls can also be provided in the area of the entry of the piles into the shaft and their discharge from the shaft. These dividing walls make it possible in a particularly simple manner to separate the treatment gases which are led through the piles in the individual zones and which have a different composition and also different temperatures.
  • the shaft In order to be able to vary the height of the shaft in accordance with the respective requirements and also to enable prefabrication, the shaft must be in an appropriate configuration of the device.

  • the grids are designed as structural units which can be inserted laterally through closable window openings into the shaft walls.
  • the grate bars In order to prevent the granules from closing the gap spaces between the grate bars with certainty, it is advisable to design the grate bars so that they have an undercut profile in cross-section in their upper part and with interchangeable, rider-shaped profile parts are equipped. These are expediently formed as horseshoes with projections pointing in the longitudinal direction of the grate bars as stops with adjacent profile parts. By means of these rider-shaped profile parts, the proportion of the free flow area as a whole or else locally per grate can be changed while the spacing of the grate bars remains the same.
  • rider-shaped profile parts of different cross-sections on one and the same grate can influence the formation of the trickle stream when the movable grate bars are transferred into the opening position. It is therefore possible to use the rider-shaped profile parts to act both on the flow through the piles and on the formation of the trickle stream in order to achieve uniformity.

Abstract

Le procédé de fabrication de coke moulé actif en tant que granulat sur la base de houille prétraitée prévoit de faire passer le granulat prémoulé par différentes zones de traitement d'un puits (1) et de l'exposer sur le parcours au procédé de carbonisation et d'activation, ainsi qu'à un traitement ultérieur. Les granulats sont amenés en tas plats adaptés à la section transversale du puits et de même épaisseur par rapport à la section transversale de celui-ci, ils sont soutenus en étages par des grilles (2) avec des intervalles libres entre elles. En maintenant des temps de séjour prédéterminés dans les divers étages, les tas traversent les zones de traitement et le puits de haut en bas. Dans les zones de traitement, ils sont traversés par des gaz ou vapeurs (31) introduits latéralement dans les intervalles séparant des tas voisins. Le passage des tas d'une grille à l'autre est effectué grâce à un mouvement régulé sortant au moins une partie des barreaux de grille (15,16) du plan de la grille, de telle manière que les granulats reforment sur la grille suivante un tas de même épaisseur par rapport à la section transversale.
