Abstract

Procédé et dispositif pour l'échange thermique, en particulier pour le refroidissement de matières en vrac à grains de grosseurs variées. La matière en vrac, amenée en continu à un appareil de traitement, est divisée en courants partiels, puis est refroidie à contre-courant par charges successives, en étant en même temps criblée et classée dans des chambres de refroidissement en forme de sections et en étant amenée à circuler, pour être refroidie encore devantage, après le classement, par charges successives dans une couche de repos et être enfin déchargée, le débit de gaz étant réglable de façon à établir un regime d'écoulement correspondant au processus de refroidissement et permettant d'obtenir des conditions de transfert de chaleur optimales. L'invention est applicable par exemple au refroidissement de clinker.
