METHOD AND APPARATUS FOR SEPARATION OF SOLID

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for separation of a solid which achieve a high separation efficiency with energy saved, require less labor and are compact and economical. SOLUTION: The solid separating apparatus 1 is so constructed as to efficiently collide/flocculate fine solid particles in a to-be-treated fluid with each other, and be settled. The apparatus 1 is separately constituted by a cylindrical swinging separation vessel 2 having two or more built-in cap-shaped cylinders 221, 222 and 223 applying a strong centrifugal force to fine solid particles 7 for flocculation/accumulation, and a settlement separation vessel 3 for settling and separating the flocculated fine solid particles 7. The swinging separation vessel 2 and the settlement separation vessel 3 are connected with each other through a pair of spraying pipes 41 and 43 spraying the to-be-treated fluid 6 and a single clear fluid rising pipe 5 in which the clear fluid 61 of the to-be-treated fluid 6 passes through the central part of the swinging separation vessel 2 and is discharged outside. The apparatus 1 and a fluid storage mechanism 9 are connected with pipes or the like to form a loop. COPYRIGHT: (C)2007,JPO&INPIT
