РЕАКТОР ДЛЯ ПОЛУЧЕНИЯ ЭКСТРАКЦИОННОЙ ФОСФОРНОЙ КИСЛОТЫ

摘要

FIELD: chemical engineering. ^ SUBSTANCE: reactor comprises branch pipes (15) and (16) for supplying natural phosphate, sulfur acid and recirculation solution of phosphorus acid to the reactor, mixing devices (3) for mixing pulp, and circulator (4) mounted within central well (5) for causing the pulp to flow through top outlet port (7) to grate (12) of the apparatus for air cooling and circulation of pulp in the zone of reactor defined by apparatus for air cooling and port (6) in the central well. Circulators (4) in wells (9) provide circulation of pulp throughout the space of the reactor and pulp flow near the baffle from both its sides. The pulp is discharged from the reactor through branch pipe (18). ^ EFFECT: enhanced efficiency. ^ 2 dwg
