Abstract (en)
[origin: US4701243A] A method of cooling and dedusting coke after leaving the coke dry cooling system comprises directing the coke at a temperature of approximately 150 DEG to 200 DEG C. into an immersion tank which has a liquid temperature of approximately 100 DEG C., thereafter conveying the coke out of the immersion tank at a selected variable speed so as to free it of fine dust. The water content of the coke after leaving the immersion tank and after an adequate evaporation time is controlled by the speed of the conveyor which is located in the immersion tank and the water content is advantageously kept below 5%, preferably from 0 to 3%. The immersion tank comprises a closed housing overlying a box-shaped tank with a continuously revolving chain conveyor located so as to extend through the tank at its upper reach for conveying the coke into the tank and which has a lower return reach which is directed outside of the tank below the tank itself.
