Abstract:
An apparatus for providing contact between a liquid and solid particles having an upright vessel with an upper outlet and a pair of lower outlets, a plurality of concentric upwardly directed inlets into said vessel with one of the outer inlets including a means for swirling its discharge around the inner inlet, means for axially adjusting the discharge position of the central inlet and means for directing oversized particles to one of said lower outlets and smaller particles to the other of said lower outlets. Such apparatus is particularly useful in providing intimate contact between solid salts and an acid, such as salt such as sodium chloride, to produce a volatile acid and sulfate granules.
