COAGULATION FLOCK DRYING METHOD AND COAGULATION FLOCK DRYING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a coagulation flock drying apparatus which is capable of recovering magnetic powder without using a bag filter even when the coagulation flock is drying-treated in a drum dryer.

SOLUTION: The coagulation flock drying apparatus forms a coagulation flock by adding a coagulant and magnetic powder in the water to be treated, recovers the coagulation flock by using a magnetic separator, and dries the recovered coagulation flock in a rotating drum type dryer. It has a rotating type magnetic filter 16 in a casing 26 in which a rotating drum for drying 12 is arranged. Here, it is preferable that the rotating type magnetic filter 16 has a magnet 18 in the inner periphery face of a drum 17, and the second scraper 22 to scrape off the attached magnetic powder at the outer periphery face as a magnetic powder attaching face.
