Abstract
A sparger system for removing sodium chlorite crystal and other crystalline particulate material in slurry form from a tank car comprises a plurality of spray nozzles from which water is expelled as a flat spray initially to dissolve sodium chlorite so as to cavitate the mass of sodium chlorite crystals, which break off in lumps into the cavity and then to impact the walls and roof of the tank car to flush off residual sodium chlorite crystal. The slurry is collected in a sump and is discharged therefrom, with additional sprays agitating the sump to break up clumps of sodium chlorite and to maintain the particulates in suspension.
