Definitions

  • the invention relates to a method for cooling and dedusting coke after leaving a dry coke cooling and an immersion tank for performing the method.
  • the object of the invention is to propose an effective method for dedusting the dry-cooled coke, in which the complex measures for dry dedusting are omitted.
  • the solution to this problem according to the invention is that the coke with a temperature of about 150 to 200 ° C in a dip tank with a liquid temperature of about 100 ° C and preferably conveyed out at an infinitely variable speed out of the dip tank and thereby freed from fine dust becomes.
  • the water content of the coke can be adjusted to a water content below 5%, preferably below 3%, after a sufficient evaporation time by regulating the speed at which the coke is conveyed out of the immersion container. It has now been found that a coke immersion time of less than 3 minutes, preferably even from 1 to 20 seconds, is particularly favorable. to maintain a low and even water content of the coke.
  • the most important advantage of the method according to the invention is the fact that all fine dust is separated from the coke pieces in the immersion container and is first taken up by the water and then transported away with the chain conveyor.
  • the coke dusts floating on the water surface are rinsed according to the invention by spraying on circulating water and / or fresh water in the coke transport direction and / or towards sieving and / or filtering devices. These sieve and filter devices are then cleaned in a manner known per se.
  • the coke breeze and the smaller pieces of coke that settle at the bottom of the chain conveyor are separated when the chain conveyor returns outside the water bath, with the coke breeze still adhering to the chain conveyor being rinsed off before entering the immersion container.
  • the coke When leaving the immersion tank, the coke should also be charged with small amounts of water to rinse off the fine dust adhering to the surface.
  • the water drawn out of the immersion tank and possibly the drip pan below the immersion tank is returned to the circuit after any additional cleaning.
  • the immersion tank e.g. B. add milk of lime or similar substances.
  • the coke can also be used when leaving the immersion tank with a dust-binding agent, e.g. B. sprayed from oily or tar-containing substances.
  • a submersible container which consists of a box-shaped, open container with a continuously rotating chain conveyor, the return of the chain conveyor being arranged outside the water bath in the open under the container bottom.
  • the Immersion tank provided a drip pan with water drain.
  • the immersion tank has a water overflow with sieve and filter devices and associated cleaning devices. These screens and filters are expediently arranged in the area of the discharge of the coke, preferably in the side walls of the immersion container
  • the hood of the immersion tank or the outlet cross section can have indirect water cooling. Above all, this keeps water loss through evaporation low.
  • the immersion container (1) according to the invention is shown schematically in a side view
  • the coke coming from the coke dry cooling is placed in a box-shaped, partially open immersion container (1) via the coke feed (15) after leaving the discharge locks via a suitable conveyor and is cooled there in a water immersion bath (3) with the help of a continuously running chain conveyor (2) the coke is conveyed out of the water bath and falls on a further conveying device when the chain conveyor is deflected on the deflection roller (17).
  • the chain conveyor (2) runs empty after the reversing station outside the immersion tank (1) outdoors under the tank bottom (4).
  • the coke breeze separated from the coke in the water immersion bath (3) is transported out of the immersion bath together with the coke by the chain conveyor (2) and falls below the container bottom (4) onto a conveyor belt (10) and is collected in a coke brew container (12) in the area the deflection roller (17) of the rotating chain conveyor (2), the residues of coke breeze still adhering to the chain conveyor are sprayed with fresh water from the water nozzles (16).
  • the fine coke dusts floating on the water surface (5) in the area of the coke feed are rinsed by spraying part of the circulating water from the water nozzles (14) in the direction of the coke discharge to the sieving and filtering devices (7).
  • the fine coke dust is initially together with the Water is led via a water overflow (6) into a filter basin which is arranged outside the coke transport direction and may need to be cleaned discontinuously.
  • the water is then recirculated via the water outlet (11) and the circulating pump (13).
  • the entire immersion container is covered with a hood (8), which has an outlet cross section (9) at the top for removing the evaporated water.
  • the walls of the hood (8) have indirect water cooling, so that part of the rising water vapor is condensed again on the walls.
  • cooling devices are arranged in the outlet cross section (9), on which the rising steam is also cooled and partially condensed again.
