Definitions

  • the invention relates to a device for discharging coke from a cooling shaft charged with cooling gases.
  • the invention has for its object to provide a device which on the one hand allows a well controllable, uniform discharge of the coke over the entire shaft cross-section and on the other hand prevents the escape of dust-laden gases into the atmosphere.
  • one or more scrapers engaging in the coke resting on the discharge table of the cooling shaft are provided, which are fastened to a support ring which is rotatably mounted and is provided with a drive, the support ring with the scraper (s) in a housing sealed from the atmosphere is arranged.
  • the scraper (s) are pivotally and / or longitudinally displaceably mounted on the support ring. This measure allows the amount of coke discharged from each individual scraper to be set precisely.
  • a collection container for the stripped coke is provided below the discharge table of the cooling shaft, to which a lock container is connected at the bottom.
  • the collecting container is provided with a conical, lifting and lowering bottom closure.
  • the invention further provides that the collecting container, which carries the discharge table, simultaneously serves as a distribution space for the cooling gas and is connected to one or more cooling gas supply lines.
  • a ring line surrounding the collecting container is preferably provided, from which branch lines lead in a star shape into the collecting container.
  • the lock container is provided with a suction nozzle for the discharge of cooling gas flowing in.
  • the lock container can also have a connecting piece for the supply of inert gas, which is under a higher pressure than that of the cooling gas.
  • the features of the invention mentioned above create a discharge system which is closed as a whole against the atmosphere and thus reliably prevents the escape of dust-laden gases.
  • the actual discharge elements consisting of the wipers attached to the support ring, make it possible to adjust the amount of coke discharged in the desired unit by changing the rotational speed and the position of the wipers. In this way it can be ensured that the coke column in the cooling shaft has a constant height and the coke is thus also subjected to constant intensive cooling.
  • the invention is illustrated in the drawing, for example.
  • the lower area of the cooling shaft is indicated by 1.
  • a metallic housing 2 on which 3 or 2 by means of vertical and horizontal support or guide rollers.
  • 4 a support ring 5 is mounted.
  • the latter carries a plurality of wipers 6 which engage in the coke embankment 7 which rests on the discharge table 8.
  • the discharge table represents the lower end of a plurality of conical metal shells 9 arranged one above the other or one inside the other, which here form an annular column of bulk goods in the discharge region of the cooling shaft. Spaces 10 are left between the individual metal shells, which serve to distribute the cooling gas.
  • a collecting container 11 for the stripped coke is provided below the discharge table 8. This is provided with a conical bottom closure 12 which - as indicated by 12 '- can be raised and lowered. In turn, a lock container 13 adjoins the collecting container 11, the lower end of which is provided with a suitable shut-off device 14.
  • the collecting container 11 is surrounded by a ring line 15 for the supply of the cooling gas.
  • Several branch lines 16 lead from this ring line and lead into the collecting container.
  • the cooling gas passes through the coke lying on the discharge table 8 or through the above-mentioned intermediate spaces 10 into the cooling shaft 1. Flowing upward in this, the cooling gas flows around the coke in the cooling shaft and cools it down, after which it is not shown here Way in the upper area of the cooling shaft is withdrawn from this.
  • the electric motor 17, which is mounted on the metallic housing 1 by means of a supporting structure 18, serves to drive the supporting ring 5.
  • the electric motor drives a gear 19 which interacts with the toothing 20 provided on the circumference of the support ring.
  • a suction port on the lock container 13 is designated, through which the cooling gas flowing into the lock container through the open bottom seal 12 is drawn off. This measure prevents cooling gas from being released when the shut-off element 14 is opened.
  • Another possibility of preventing the escape of cooling gas from the lock container 13 is to close the lock container with an inert gas from the connection socket designated by 22 act upon.
  • the pressure of the inert gas must be greater than the pressure of the cooling gas, so that it cannot flow into the lock container when the bottom closure 12 is open.
