Abstract
PURPOSE: To provide high-concentration, high-purity Ca(ClO)2.H2O slurry having a smaller amount of hardly water-soluble solid, by supplying Ca(ClO)2 dihydrate slurry contg. hardly water-soluble solid from the top of a classifier tower, and by supplying aqueous Ca(ClO)2 solution from the bottom of the tower.
CONSTITUTION: To 100pts.wt. of Ca(ClO)2 dihydrate, not more than 5pts.wt. of hardly water-soluble solid, such as CaCO3 or SiO2, is added. The obtained slurry is supplied to the top opening 2 of a classifier tank maintained at 10W35°C. At the same time, an aqueous Ca(CaCl)2 solution or Ca(ClO)2 dihydrate slurry contg. not more than 1.5wt% of hardly water-soluble solid is supplied to the lower opening 5 of the classifier tank and is given uprising flow in the classifier zone 1. Slurry contg. a larger amount of hardly water-soluble solid is taken out of the overflow outlet 3. And, high-concentration, high-purity Ca(ClO)2 dihydrate slurry contg. a smaller amount of hardly water-soluble solid is discharged from the outlet 4.
