COOLING DEVICE FOR HOT BULK MATERIAL

摘要

A cooling device for hot bulk material (1) has a cooling tower (2) with a vertical main axis (3), said hot bulk material (1) being cooled in the cooling tower by means of a gas flow (4). The device has a feeding device (5) by means of which the hot bulk material (1) is poured into the cooling tower (2) from above such that the hot bulk material (1) is accumulated in the cooling tower (2). The device has a removing device (7) by means of which the bulk material (1) in the cold state is removed from below from the cooling tower (2) such that the bulk material (1) that remains in the cooling tower (2) slides downward. The device has a gas delivering device (8) by means of which the gas flow (4) is delivered through the cooling tower (2). The device has a discharging device (9) via which the gas flow (4) is discharged from the cooling tower (2). The cooling tower (2) is equipped with a plurality of gas flow guides (13) which extend radially inwards towards the main axis (3) starting from inlets (14) that lie in the tower outer wall (6). The gas flow guides (13) are designed as elongated guides that have outlets (15) for the gas flow (4) along the guide length when viewed in the respective extending direction of the guide such that the gas flow (4) is led into the hot bulk material (1) that is located in the cooling tower (2). The gas flow guides (13) lie in the central region (16) of the cooling tower (2) when viewed in the direction of the main axis (3), and the discharging device (9) lies in the upper region of the cooling tower (2). The gas flow (4) thus flows through the hot bulk material (1) that is located in the cooling tower (2) from bottom to top.
