Abstract
An installation for purifying particulate solids, especially a salt purification facility, comprises a vertically standing purification vessel (1) which has on top a fill aperture (10) for the solids to be purified, below an outlet aperture (11) for the purified solids and at least one conical region (12, 13). At least one feed line (30, 31) into the purification vessel (1) and at least one downwardly directed and downwardly widening nozzle (33) are provided to feed in a purification brine in counterflow to the flow direction of the solids to be purified. The at least one conical region (12, 13) of the purification vessel (1) has an angle of conical opening of 10 DEG to 30 DEG . This prevents clumping or channeling within the purification vessel, thus enhancing efficiency and prolonging uninterrupted service life without impairing the action of any downstream processing apparatus such as centrifuges.
