Abstract

PURPOSE: To perform efficient and continuous production of aqueous slaked lime solution by a method wherein slaked lime is charged and stacked in a inverse-cone type tank having stirrer blades at its bottom, water is supplied from the bottom to fluidize and dissolve the slaked lime, which is discharged from the top of the tank.
CONSTITUTION: Stirrer baldes (preferably turbine type) 7 and water supply inlet 6 are installed at the bottom of a slaked lime dissolving tank 1 shaped into inverse cone type (heat-cut inverse circular cone type or heat-cut inverse pyramid type) at least at the lower part of slaked lime fluidized layer 2. At the top of the tank 1, a slaked lime supply inlet 3 and a slaked lime solution outlet pipe 4 are installed. Using the above equipment, a required amount of slaked lime is charged into the tank 1 filled with water, the stirrer blades 7 are rotated at peripheral speed of about 1m/s or less, service water is supplied from a constant pressure water tank 14 to the tank 1 via pipe 17, flow meter 18, water supply inlet 6, at flow rate of about 1mm/s or less. Then, aqueous slaked lime solution is overflowed receiver 5, which is continuously discharged from outlet pipe 4.
