Definitions

  • the invention relates to a method for producing a briquette for hot briquetting by pyrolytic decomposition of baking hard coal in a mixture with two to five times the volume of fine-grained, thermally largely stable substances and to an apparatus for carrying out the method.
  • Such a method for producing a briquette is known from GB-A-1 168 283, which is based on priority applications DE-A-1571710 and 1671377.
  • the methods described in these two documents relate in particular to measures to achieve a certain level of the Urteer yield of the briquetted material at the time of deformation.
  • the yield from Urteer should amount to 0.2 to 0.8% and according to DE-A-16 71 377 between 0.07 and 0.2%.
  • the main task was to achieve the maximum possible de-emptying of the briquetted goods.
  • Mixing temperatures of 450 ° C to 530 ° C and a residence time of the briquetted material of 1 to 15 minutes are already mentioned as important process features.
  • the solid components are introduced into a container in which the mixing and degassing takes place.
  • the container contains an agitator with a vertical axis.
  • the briquetted material is fed to the roller press via a feeder in the manner of a cellular wheel, which rotates about a horizontal axis. This allocator is not described in detail.
  • the object of the invention is therefore to propose a method and a device for carrying out this method, with which a briquetted good consistency for the hot briquetting is produced, this briquetted material being evenly distributed over the roller width of more than 400 mm, always briquettes uniform consistency and strength and very high throughput rates of more than 7 t / h up to about 70 t / h can be achieved.
  • the briquetted material should remain in the moving bed reactor for a certain time, since on the one hand sufficient pyrolysis and degassing must take place - because insufficiently degassed, specially de-emptied briquette material tends to burst again after pressing, on the other hand there is a risk that the product that is too strongly degassed will The fat coal loses its binding ability and the product silted up and thus tends to extremely high abrasion. Finally, according to the invention, the briquetted material should be uniformly distributed over the entire briquetting roller width in a certain time using certain measures.
  • the briquetted material should finally be pre-compressed in a space sealed against the atmosphere of the press chamber and distributed evenly over the entire width of the roller.
  • air penetration and thus the formation of an explosive mixture is prevented.
  • the briquettes fall into an open space so that the press can be easily monitored.
  • a moving bed reactor which consists of a container in which one or more agitators with a vertical axis of rotation and horizontal agitator arms are arranged and whose distribution zone below consists of a distributor with a horizontal central axis of rotation, with the aim of achieving an intensive mixing and Kneading movement in the distribution zone is proposed according to the invention that fixed arms are attached to the end walls of the housing of the distribution zone, which project in the axial direction into the cylindrical distributor basket.
  • the number and shape of the distributor webs which in the direction of rotation in the middle, i.e. at half the length of the distributor basket, advance and are bent or angled towards the ends.
  • the distribution webs which are angled backwards in the running direction from the prescaler basket, create a force component with the aid of which sufficient material is transported to the outside.
  • Fixed arms are attached to the end walls of the housing of the distributor zone and protrude axially into the cylindrical distributor basket. It is also achieved that the briquetting material arriving in the middle at the transition to the distribution zone is mixed again with the briquetting material emerging at the outer edges below. In this way, a possibly not yet uniform composition of the briquetted material is compensated for by simple means due to the different peripheral speeds distributed over the radius.
  • the part of the moving bed reactor with a vertical axis of rotation can, according to claim 6, in particular consist of an upper and a lower cylindrical region, the outer diameter in the upper region being about 1.5 to 5 times, preferably 1.5 to 3 times, so is as large as in the lower area and the transition area between the upper and lower area narrows in a funnel shape and the lower area of the moving bed reactor merges into the distribution zone without constriction.
  • the horizontally rotating stirrer arms in the upper region have approximately 1.5 to 5 times, preferably 1.5 to 3 times, the amount compared to the stirrer arms in the lower region. With the help of this device, a different average speed of the briquetted material is achieved at the same angular velocity in the upper and lower region.
  • a much higher speed is provided in the upper area for mixing the insert components. Due to the considerably larger diameter of the moving bed reactor in the upper area, there is also a considerably larger outlet area for the degassing gas escaping upwards, so that the outlet velocity of this gas can be kept relatively low. This ensures that only very small amounts of fine dust particles are entrained by the degassing gas.
  • FIG. 1 shows the moving bed reactor with the upper and lower region (2, 4) and the distributor zone (5) directly adjoining it at the bottom as well as the two double roller presses (1a, 1b).
  • the components with different temperatures are introduced into the moving bed reactor via at least two inlet openings (20).
  • the drive (15) of which is arranged above the moving bed reactor, the horizontal stirring arms (3) are fastened uniformly at different heights.
  • the outlet opening (19) for the degassing gas is also arranged in the upper cover of the moving bed reactor.
  • the vertical agitation axis (16) is guided at the bottom in the bearings (17) and (18), which are supported on the inside by the walls of the traveling reactor.
  • the briquetted material arrives directly in the distribution zone (5), in which a distribution basket (6) rotates about a horizontal axis of rotation (22).
  • the distributor basket (6) is equipped on the circumference with a series of distributor webs (7), with the aid of which the brittling material is pressed into the lower lateral outlet opening (10) and is distributed evenly over the length of the rollers.
  • the distributor webs (7) are bent in the middle and angled at the ends in the direction of rotation of the distributor basket (6) to the rear. It is thereby advantageously achieved that the briquetting material is also exchanged in the axial direction of the distributor basket.
  • the two rollers are also arranged in plan view. On the one hand, they consist of a fixed roller (1 a) and a loose roller (1b) which can be moved in the radial direction and which is pressed against the fixed roller with a specific, adjustable contact pressure.
  • the dies (21) for the briquettes are arranged on the circumference of the rollers.
  • the distributor zone (5) is shown again in itself, in particular one can see the storage of the distributor basket and the connection of the distributor webs with the central drive axis. Below the distributor basket, the amount of the briquetted material is adjusted using the control flap (12), which rotates about the axis of rotation (13). At the ends of the rollers there are closure flaps (11) which are attached at (14).
  • (23), (24) and (25) denote the fixed arms directed from the outer wall of the moving bed reactor in the radial direction and (26) the inwardly directed arms in the axial direction. They can either be distributed uniformly around the circumference of the moving bed reactor or else only on one side, as shown in FIG. 1.
