SHAFT-LIKE DRY COOLER FOR COKE

摘要

The invention relates to a shaft-like dry cooler for coke cooled by gases conveyed through the coke, the cooler comprising a top antichamber below a charging opening, a cooling chamber under the antichamber and having a gas inlet and a coke outlet at the bottom end, and a gas outlet in the cylindrical wall between the antichamber and the cooling chamber. In order to ensure that the coke descends substantially uniformly, the shaft in the cooling chambers is divided by radial walls, which abut a central masonry core, into a number of (e.g. three) shaft-like chambers. A prop for deflecting the descending coke from the central region can be placed at the centre of each component shaft. The cooling gas can be supplied through a pipe having a downwardly directed opening below the central masonry core. Additional cooling gas can be supplied via an annular chamber surrounding the outlet cone.
