Abstract

An improved salt basket for dewatering solids. The salt basket is ideally configured for use with a crystallizer or evaporator producing salts from industrial wastewaters. The salt basket system includes a pressurizable vessel having a screen floor situated above a bottom liquid collection head, an inlet for the brine/solids slurry from which solids are to be separated and dried, an inlet for air, an inlet for steam (the latter two inlets may be combined, where convenient), a feed brine inlet and a drain outlet (these two may by combined where convenient into a combination feed/drain connection), an automated system for introducing feed brine, and an automated system for removing the solids product, the latter system including an automated door with a fail safe clamp system design.
The vessel shape preferably includes sidewalls of substantially circular cross section with downwardly and outwardly sloping walls (either conical or flaring somewhat at the bottom) which are free from protuberances which would tend to prevent salt crystals from falling downwardly. A pivotally attached lower door has a hydraulic failsafe closure mechanism and looking safety latches to prevent the door from inadvertently opening. The process control design minimizes exposure of the salt basket interior to supersaturated solutions with precipitating solids therein, thus reducing coaling of the salt basket, by introducing feed brine rather than magma (crystal/concentrated liquor slurry) to the salt basket between crystal harvest cycles.
