ι 2 hot conveying gases are heated up by combustion Claim: to be generated by gases. Continue to form hot gases in the delivery line due to combustion Process for the continuous production of the fine coke shaped coke carried away by the heat carriers particles by coking of shaped coal s. by means of circulating fine-grained For carrying out the method according to the Heat transfer medium, where carbon moldings and hot main patent is used, as in the attached drawing Heat transfer medium shown at the top of a reactor, one from above with a bed 2 are abandoned, the carbon moldings with the fine-grained heat transfer and carbon moldings Heat carrier !! from top to bottom through the xo almost completely filled reactor 1, which is at his Reactor sink, the hot coke at the lower lower end of one or more catch spaces 4 be-end from the heat transfer medium by means of an inclined frame, which is connected to an overflow weir 6 with one or more Grids is separated and cooled and the reren inclined grids 7 are connected Heat transfer medium with simultaneous recovery and its3odenGiU 'inlet pipes5 for the circulation pneumatically returned to the reactor 15 turbulence of the bulk material. Advertise the reactor according to patent 1571639, as a result, a fluidized bed channel 12 is located under the grating 7 indicates that the ones from the cooling shaft for receiving those that have fallen through the grille withdrawing heated gases and / or the exhaust gases heat transfer medium, through which one of in a firebox the heat transfer line of the preheater 15 flowed through highly heated gases generated tongue or pre-carbonization of the raw coal form 20 conveyor line 14 is passed, which is in the amount of linge serve. Fluidized bed surface of the fluidized bed channel 12 one or several openings 13 for the suction of whirled up Heat carriers and up in a settling space 17 opens which has a flue pipe 18 25 has and the one with a funnel-shaped lower Part 19 opens into the reactor from above via a dip tube 20. The patent 1571639 relates to a method for introducing additional gases into the bed 2 continuous production of molded coke can be through, are attached to the reactor 1 Gaseinfüh-coking of coal moldings by means of 30 approximate tubes 3 in the circuit. Furthermore, it is essential, guided fine-grained heat transfer medium, with coal that the free space under the grating 7 with the moldings and hot heat transfer medium at the upper end of the fluidized bed 12 are abandoned via one or more dip tubes 8 of a reactor, the carbon form is connected and that in the lower part of the Förlinge with the heat carriers from top to bottom derrohres 14 for the combustion of gases in the Fördurch the reactor sink, the hot coke at 35 derrohr one or more gas pipes 16 are introduced lower end of the heat carriers by means of oblique. From the surface of the grate 7 leads to the grids placed and cooled and the discharge of the coke moldings is a pipe to the cooling-heat carrier with simultaneous reheating shaft 9, which in turn is pneumatically returned to the reactor via gas lines, a heat exchanger 11, which is characterized in that in the medium 40 The cooled coke moldings are drawn off from the cooling shaft 9 through the discharge area of coal moldings and heat vent 10,
girders in the upper part of the reactor with the help of the It has now been found that it depends on the nature of the to The distillation and coking charcoal moldings that are released can be advantageous, gases by appropriately dimensioning the cross-section to preheat the raw briquettes or even before Reactor, selection of coal in terms of smoldering. According to the invention one draws to this content of volatile constituents and the quantitative purpose of the ratio for cooling the coke moldings from moldings to heat carriers and used hot circulating gas from the cooling shaft 9, if necessary by injecting additional gases and diverts it, as in the adjacent character-vortex condition is maintained and that hot voltage shown, via pipe 21 in one of the Molded coke and heat transfer medium at the lower end of the 50 reactor 1 upstream container 22. In this Reactor at one or more points with short, the briquettes introduced from above are im Gas impulses given into the bulk material column are preheated or pre-overflow weir via a countercurrent to the circulating gas be discharged pneumatically. smoldering. The pretreated charcoal moldings are The discharge of the bed takes place in such a way that molded coke and heat transfer medium are channeled into the reactor via line 23 at the lower end 55; At the same time, the non-pretreated reactor can also be introduced into the bulk material column at one or more points with curled briquettes via a lock into the reactor. To improve the distribution, an overflow weir is pneumatically discharged and the briquettes in the bed 2 are heat-sealed by means of one or more inclined frame supports over a grate or grates placed through the immersion tube 20 separated from each other 60 inner tube introduced into the reactor. That in evaluation. The holder 22 of the cooled circulating gas passing through the grids flows via line 24, heat transfer medium is fed into a gas flow and the condensation device 25, in which any fluidized bed channel that may have flowed, is discharged and the carbonization products and water produced there are pneumatically discharged into a return to the reactor Cooling shaft 9 back. Excess delivery line fed in, while the coke-form gases and vapors can be discharged via line 26 from linge via a cooling shaft. be withdrawn from this circulatory system.
The fine-grained heat carriers are also the exhaust gases from the delivery line 14 can during the pneumatic return to the reactor with over the exhaust pipe 18 into the container 22
