METHOD FOR DESIGNING SLURRY TREATMENT PLANT AND SLURRY TREATMENT PLANT

摘要

PROBLEM TO BE SOLVED: To provide a method for designing a slurry treatment plant the slurry treatment process of which is optimized easily while considering compatibility between filter cake and the drying condition or drying method thereof.SOLUTION: The method for designing the slurry treatment plant comprises the steps of: measuring the dehydrating time F and the drying time D of a dehydrating/drying unit, in which slurry is dehydrated mechanically in a filter press to form the filter cake and the pressure in the filter press is reduced to the upper limit pressure of 200 millibar or lower and the temperature of a filter plate arranged in the filter press is kept at the lower limit temperature of 40°C or higher to dry the formed filter cake; deciding to dispose a drying unit, in which the drying method different from that of the dehydrating/drying unit is used, in the slurry treatment plant when a relationship of D>mF(m=10-14) is satisfied; and deciding to dispose the dehydrating/drying unit in the slurry treatment plant without disposing the drying unit when another relationship of D
