摘要： The invention relates to a granulation installation (10) for a melt produced in a metallurgical plant, especially for blast furnace slag. It has a water injection device (20) for quenching and thereby granulating the melt and a granulation tank (18) for collecting water and granulates. A steam condensation tower (30) is located above the granulation tank (18) for collecting steam generated in the tank (18). The tower (30) has a steam condensing system with a water-spraying device (40) and a water-collecting device (42) below the water-spraying device (40). According to the invention, the tower (30) is equipped with a stack (60) for selectively evacuating excessive steam to the atmosphere. This stack (60) has an inlet (62) communicating with the lower zone (44) of the condensation tower (30) and an outlet (64) arranged to evacuate steam to the atmosphere above the condensation tower (30). Furthermore, the stack (60) is equipped with an obturator device (70) for selective evacuation of steam through the stack (60). The installation according to the invention may process an increase of 60% of slag, e.g. around +5 t/min of slag in a system having a condensation capacity designed to handle a maximum slag flow rate of 8 t/min, without any risk of steam backflow in the granulation area.

摘要： An installation (100) for processing a metallurgical melt, in particular blast furnace slag, comprises at least one granulation unit (110; 120), which produces slurry of granulates and water, and a main dynamic dewatehng unit (130) connected downstream the granulation unit. The main dewatering unit (130) comprises a mobile component, in particular a rotary dewatering drum (132), for separating slurry into granulatesand water. According to the invention, the installation includes: - a slurry overflow (150) arranged upstream of or at the inlet of the main dewatering unit (130) and upstream of the water outlet (142), from which water is recovered from the main dewatering unit (130), this overflow being configured for draining slurry in excess of the unit's dewatering capacity; - a secondary dewatering unit (160) having an inlet (162) connected for receiving excess slurry from the overflow, a first outlet (164) for returning a secondary dewatered fraction to the main dewatering unit and a second outlet (166) for recovering water. The installation is configured to drain excess slurry so as to preclude excess slurry from reaching the water outlet (142) and to separate drained excess slurry into a secondary dewatered fraction returned to the main dewatering unit (130) and into a secondary water fraction recovered without passing through the main dynamic dewatering unit (130). A corresponding method of processing molten material, in particular for granulating blast furnace slag, is also proposed.
