A method for the cooling of cement clinker and cement clinker cooler

摘要

The present invention relates to a method for the operation of a radiator (1) and a corresponding cooler (1) for the uniform cooling of hot cement clinker (14), wherein the radiator (1) at least one inlet region (3) for receiving of the cement clinker (14), a recuperation zone (4), a final cooling region (5), at least one fan (6) for blowing cooling air (8) in the recuperation zone (4), at least one fan (7) for blowing cooling air (8) in the final cooling region (5), a tertiary air line (11) for deriving the heated cooling air (8), a discharge region (12) for discharge of the cooled cement clinker (14) and at least one conveying means (13a, 13b) for the transport of the cement clinker (14) through the radiator (1), the hot cement clinker (14) in the cooler (1) by means of an inlet opening (2) into the inlet area (3) is dropped, the cement clinker (14) of the conveying means (13a, 13b) from the inlet region (3) by means of the recuperation zone (4) and the final cooling region (5) to the outlet region (12) is transported, and of the fans (6, 7) ambient air (23) is used as cooling air (8) and drawn into the radiator (1) is blown.According to the invention, a cooling of the cement clinker (14) in the final cooling region (5) by means of a with a fine water mist (17) enriched cooling air (8) is provided, whereby the of the at least one fan (7) of the final cooling region (5) where the ambient air is aspirated (23) in the region of its intake connection (16) by at least one ultrasonic nebulizers (15) or at least one binary nozzle (air / water) with a fine water mist (17) is enriched.
