Definitions

  • the invention relates to a coke dry cooling device with a shaft, consisting of a prechamber with coke feed, a cooling chamber arranged below the prechamber, which has a coke discharge and an inert gas supply in its lower region, and an inert gas outlet connected to the prechamber, a vertically oriented one in the prechamber and the jacket that delimits the coke cone is arranged, which forms an annular space as a path for the inert gas in the area of the inert gas discharge with the wall of the antechamber and in which the inert gas is returned to the inert gas supply after cooling and dedusting.
  • the prechamber In coke dry cooling, the prechamber is given so much hot coke that there is always a certain amount of coke in the prechamber at a largely uniform temperature.
  • the coke sinks evenly from the antechamber into the cooling chamber. Inert gases, which are conducted in countercurrent and circulation, cool the coke here.
  • the coke also gives off its heat to cooling water conducted in pipes, which can be used either directly or with the interposition of a heat exchanger for steam generation (DE-OS 33 32 702).
  • the inert gas flowing out at the gas outlet of the pre-chamber is first passed through a pre-deduster for coarse dedusting, before it enters one Waste heat boiler arrives in which it is cooled in several stages.
  • the waste heat boiler is followed by a fine deduster, so that the dust-free inert gas flow can be fed back to the inert gas supply to the cooling chamber with the aid of a blower.
  • This coke dry cooling device is costly and requires a relatively large amount of space for the dedusting and cooling of the inert gases. This means long distances for the inert gas flow and also relatively high pressure losses, for which the pre-deduster, the waste heat boiler and also the fine deduster are responsible. The energy expenditure for operation is correspondingly high.
  • the object of the invention is to reduce the costs, the space requirement and the energy expenditure for the operation of a dry coke cooling device and nevertheless to ensure an advantageous heat balance.
  • annular space is designed as an afterburning chamber into which several gas lines emanating from the prechamber above the coke pouring cone and, alternately, air feeds open, and in that pipes through which cooling water flows are arranged on the wall of the annular space.
  • the heat released in the annulus is partially absorbed by the cooling water which flows through the pipes lining the annulus.
  • the tubes in the annular space are connected to upper and lower collectors, the upper collectors being connected in a known manner to a consumer or to a steam drum.
  • At least one cyclone dust collector for the fine dedusting of the inert gases is arranged directly behind the inert gas discharge, in particular if its inner wall consists of heat exchangers through which cooling water flows.
  • the cyclone dust collector can also take over the fine dust removal in addition to the coarse dust removal, because the inert gases that have only partially cooled in the annular space are still so high that they have a relatively low viscosity, which supports the fine dust removal as well as the high gas velocity in cyclone duster.
  • a separate pre-deduster with high pressure loss can be dispensed with.
  • the cyclone duster provided on its inner wall with heat exchangers is at the same time, because of the high turbulence, ideally suited for cooling the inert gases with minimal pressure loss, so that in principle it is also possible to do without a separate waste heat boiler.
  • the heat exchangers of the cyclone dust collector can have double-walled heat exchanger surfaces.
  • the heat exchangers preferably consist of pipes which are connected to upper and lower collectors.
  • the heat exchanger can be designed as a superheater in a cylindrical region of the cyclone adjoining the inert gas discharge.
  • a waste heat boiler can be connected downstream of the cyclone dust collector for the usual operating modes.
  • inert gas stream including the flammable gases that are entrained during the coke cooling, such as carbon monoxide, hydrogen, hydrocarbons, etc.
  • inert gas stream including the flammable gases that are entrained during the coke cooling, such as carbon monoxide, hydrogen, hydrocarbons, etc.
  • the coke drying cooling device shown includes a shaft with a prechamber 1 and a cooling chamber 2 arranged underneath.
  • the prechamber 1 has a coke feed 3 at the upper end.
  • a jacket 6, preferably made of refractory material, is arranged in the prechamber 1 and is so large that that an annular space 15 remains between the wall 14 of the prechamber 1 and the jacket 6. In the vertical direction, the jacket 6 ends at a distance above the cooling chamber 2 in the region of an inert gas vent 16 which is connected to the annular space 15.
  • the lower part 20 of the cooling chamber 2 is conical and ends above a coke discharge 21.
  • a ring line 22 runs around the lower part 20 of the cooling chamber 2, from which gas outlets opening into the cooling chamber 2 extend, which are not shown. Only a central gas outlet 26 is shown. Each gas outlet can have an adjustable shut-off valve.
  • the ring line 22 is connected to an inert gas supply 28 with a fan 40.
  • a plurality of lines 43 extend from the antechamber 1 above the coke cone 42 and open into the annular space 15 from above through a constriction 30 of the wall 14.
  • the lines 43 are evenly distributed over the circumference of the annular space 15 and arranged alternately with air inlets 18 which open into the annular space 15 from above in the same way.
  • the annular space 15 is lined on the inside and outside and on the top with tubes 44 through which the cooling water flows and which are connected to the lower collector 45 and the upper collector 46.
  • the lower collectors 45 are supplied with water at 47.
  • the upper collectors 46 are connected to a steam drum 49 via a line 48.
  • a cyclone duster 50 is connected directly to the inert gas discharge 16.
  • the cyclone duster 50 has a cylindrical part 51 at the level of the inert gas discharge 16 and below it the usual conical part 52.
  • the inner wall of the cyclone duster 50 is formed from heat exchangers through which cooling water flows.
  • the heat exchangers are arranged in groups one above the other.
  • the heat exchangers consist of vertically arranged tubes 53 in the cylindrical part 51 and correspondingly arranged tubes 54 in the conical part 52.
  • the tubes 53 and 54 are connected to lower collectors 55 and 56 and upper collectors 57 and 58, respectively. As shown, water is supplied to the lower collectors 55, 56 at 59 and 60, respectively, which is removed from the steam drum 49.
  • the upper header 57 of the cylindrical part 51 is connected to a consumer line 61, the upper header 58 of the conical part 52 is via a line 62 connected to the steam drum 49.
  • the heat exchanger of the cylindrical part 51 is designed as a superheater and the heat exchanger of the conical part 52 as an evaporator.
  • the tubes 53, 54 and their collectors 55 to 58 are embedded in the wall of the cyclone dust collector 50 in the embodiment shown, so that they are simultaneously provided with wear protection 63.
  • the cyclone duster 50 has a usual dust discharge 64 at the lower end.
  • a further heat exchanger 65 is connected to the cylindrical part 51 of the cyclone duster 50 and is connected to the steam drum 49 via corresponding lines 66, 67.
