Process for the manufacture of persalt particles |
摘要 |
The present invention relates to an apparatus for the continuous manufacture of solid particles of alkali metal persalts by reaction of an aqueous hydrogen peroxide solution with an aqueous solution of an alkali metal salt and crystallization of the persalt. The persalt is formed in a crystallizer classifier, which is made up of stirred region and a growth region for the persalt crystals a non-stirred clarifying region for the solution and a classification region for the particles obtained by elutriation in a liquid stream withdrawn in the clarifying region.
