Résumé
The invention relates to a system for cooling and reducing fluoride emission from a hot, spent anode butt removed from an electrolysis cell. The system comprises an elongated fluidised bed cooling chamber comprising particles of alumina and conveyor means for transporting a hot, pent anode butt through the fluidised bed. A lower air distributor is provided for injecting fluidising air into the chamber to create the fluidised bed and an upper air distributor is provided which is adapted to direct fluidised particles into contact with the top surface of the hot anode butt, whereby the fluidised bed surrounds the hot anode butt and significantly reduce fluoride emissions from the hot anode butt.
