Processing method of Prussian blue type complex, treatment apparatus of Prussian blue type solid in solid form, and treatment equipment of Prussian blue type complex in slurry form

摘要

PROBLEM TO BE SOLVED: To provide a method of treating a Prussian blue type complex while selecting a treatment method according to a state of the Prussian blue type complex.SOLUTION: A method of treating a Prussian blue type complex comprises: a determination process S01 of water content, in which the water content of the Prussian blue type complex is determined; and a treatment process S02 of the Prussian blue type complex, in which the Prussian blue type complex is treated according to a determination result of the water content. The treatment process of the Prussian blue type complex includes: a solid treatment process in which, in the case where the water content of the Prussian blue type complex is low and the Prussian blue type complex is in a solid state, the Prussian blue type complex is pulverized, the pulverized Prussian blue type complex is continuously charged into a first heating container, and the Prussian blue type complex is thermally decomposed; and a slurry treatment process in which, in the case where the water content of the Prussian blue type complex is high and the Prussian blue type complex is in a slurry state, heated air is supplied into a second heating container where a fluid medium exists, the slurry-state Prussian blue type complex is charged into the second container, and the Prussian blue type complex is thermally decomposed.
