Device for precipitating ferromagnetic particles from suspension, has two magnets that are movable in circulation direction around reactor such that distance changes continuously between magnets and reactor

摘要

The device (1) has a tubular reactor (2) through which suspension (4) flows, where a magnetic field produced by two magnets (6, 7) acts on the tubular reactor. The magnets are arranged in a flow direction of the reactor in a spaced manner. The magnets are movable in a circulation direction around the reactor such that the distance changes continuously between the magnets and the reactor. The magnets are movable in a circular or ellipsoidal orbit. The magnets described a rotating motion about rotational axes (8, 9) lying outside of the reactor.
