| 摘要 |
The invention relates to a device and method for distributing a lumpy bulk material, in particular, at least partially prereduced iron ore, on an expansive surface, especially on a static bed. Said surface extends inside a reactor or vessel used in physical or chemical process technology, especiall y inside a reactor of a smelting works, for producing pig iron or steel intermediate products, and the lumpy bulk material is charged by means of at least one charging device, which has at least two, in particular, rotational ly symmetrical drop shafts, which are preferably arranged at the same distance from the vertical longitudinal axis of the reactor. At least one portion of the bulk material, particularly after having been introduced into the drop shaft, is distributed, before striking the expansive surface, on a scatterin g device, which is assigned to at least one of the drop shafts, preferably inside the drop shaft. The distribution of the bulk material ensues, when viewed from above, in a radial and/or tangential direction.
