ABSTRACT:
A sparger system for removing sodium chlorate crystal and other particulate material in slurry or solution form from a tank car comprises a plurality of spray nozzles from which water is expelled as a flat spray initially to dissolve sodium chlorate so as to cavitate the mass of sodium chlorate chlorate 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 chlorate crystal. The slurry is collected in a sump and is discharged therefrom, with additional sprays agitating the sump to break up clumps of sodium chlorate and to maintain the particulates in suspension.
