| 摘要 | PURPOSE: To readily take out polluted substances in one process as air bubbles by introducing a suspension of fibrous substances mixed with air into a flotation separating tank having a specific structure. CONSTITUTION: Two annular chambers are concentrically and adjacently provided and a partition 24 is provided between them. A suspension of fibrous substances into which air is blown is introduced to inside of a first partitioned chamber from openings of introducing pipes 27 and 20 provided at a bottom part of the first partitioned chamber and raised in the chamber, then flowed into a second partitioned chamber by getting over the partition 24. Useful substances are introduced from a discharging port 25 to an overflow pool by a pipe. Polluted substances are sucked by a sucking nozzle 4 located at upper parts of both partitioned chambers and ejected together with air bubbles. COPYRIGHT: (C)1989,JPO |
