Definitions
- the invention relates to a method for producing a briquette for hot briquetting according to the preamble of the main claim and to an apparatus for carrying out the method according to the preamble of claim 7.
- Such a method for producing a briquette is known, in particular from D-PS 15 72 710 and 16 71 377.
- the methods described in these two patents relate in particular to measures for achieving a certain measure of the primal yield of the briquette at the time of deformation.
- the yield from Urteer should amount to 0.2 to 0.8% and according to DE-PS 15 71 377 it should be 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 are already important process features up to 530 C C and a residence time of the briquetted material from 1 to 15 minutes.
- the object of the invention is therefore to propose a method and a device for carrying out this method, with which a briquette material is produced which is as uniform as possible for hot briquetting, this briquette being evenly distributed over the roll width even with roll widths of more than 400 mm, there are always briquettes of 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 briquette in the moving bed reactor should determine one linger for a long time, because on the one hand sufficient pyrolysis and degassing must take place - because insufficiently degassed, specially de-briquetted material tends to burst again after pressing - on the other hand, if the product is too degassed, there is a risk that the carbon will lose its ability to bind and that Product silted and thus tends to extremely high abrasion.
- the briquette should be distributed uniformly over the entire briquette range in a certain time using certain measures.
- the briquetted material in the moving bed reactor is to be kept in a constant mixing and kneading movement by first holding it in a mixing and kneading movement which rotates predominantly parallel to the roller axes and is doing so at an average speed of less than 3 cm / s due to gravity sinks at the bottom and at the end is distributed evenly over the entire width of the roller in a rotational movement almost perpendicular to it.
- the briquetted material is to be pre-compressed in a space protected against the atmosphere of the press chamber and is to be distributed evenly over the entire width of the roller.
- air is prevented from entering and an explosive mixture is prevented.
- the briquettes fall into an open space so that the press can be easily monitored.
- a moving bed reactor has proven particularly useful, in which the horizontally rotating mixing arms in the upper region are approximately 1.5 to 5 times, preferably 1.5 to 3 times, longer than one another have the mixing arms in the lower area.
- the horizontally rotating mixing arms in the upper region are approximately 1.5 to 5 times, preferably 1.5 to 3 times, longer than one another have the mixing arms in the lower area.
- the characterizing features of claim S are provided for distributing the briquetting material in the distribution zone over the entire width of the rollers.
- the number and shape of the distributor webs which in the direction of rotation in the middle, i. H. at half the length of the distributor basket, advance and bend towards the ends or are angled.
- the distributor webs which are angled backwards in the running direction from the distributor 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 possible not yet uniform composition of the briquetted material is compensated for by simple means due to the different peripheral speeds distributed over the radius.
- FIG. 1 shows the device according to the invention of the moving bed reactor with the upper and lower regions of the pyrolysis zone and the distribution zone and the two roller presses.
- FIG. 3 shows in cross section and in longitudinal section the distributor zone with the distributor basket and the control flaps arranged underneath.
- FIG. 4 is a plan view of the distribution zone, the housing being open and the distribution basket with the distribution angled at the end being visible.
- FIG. 1 In the diagram ti see the compilation of FIG. 1 is the moving bed reactor with the upper and lower region (2, 4) and the distributor zone (5) directly adjoining it at the bottom and two double-roll presses (1a, 1b) are shown, via at least two inlet openings (20) the components with different temperatures are introduced into the moving bed reactor.
- 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 stirring axis (16) is guided in the bearings (17) and (18) below, which are supported on the inside of the walls of the traveling reactor.
- the briquetted material goes directly into 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 briquetted material is pressed into the lateral lower outlet opening (10) and distributed evenly over the length of the rollers becomes.
- the distributor webs (5) are bent in the middle and angled at the ends in the direction of rotation of the distributor basket (6) to the rear.
- the briquetting material is advantageously exchanged in the axial direction of the distributor basket.
- the two rollers are also arranged in de r top view. On the one hand, they consist of a fixed roller (1a) and a loose roller (1b) which can be moved in the radial direction and which is pressed against the fixed roller with a certain 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 particular the storage of the distributor basket and the connection of the distributor webs to the central drive axle can be seen. 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) are designated by the outer wall of the moving bed reactor in the radial direction and (26) the inwardly directed in the axial direction arms. 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.
