US 12,654,179 B2 · Flocculation cyclone device, marine plastic removal system using the same, ship provided with the system, and operation method for the ship

Abstract

Conventional liquid cyclone devices tend to break flocs and thus cannot be used for floc separation. Further, there are no ballast water treatment devices that can simultaneously remove plastics and microplastics floating in the sea. In addition, there are no ships or ship operation methods that address the problem of pollution due to plastics and microplastics floating in the sea. To achieve cyclone separation of a fluid including easily broken flocs, flocs that include a magnetic body are guided by means of centrifugal force and magnetic force to a flow in the vicinity of an outer shell of a cyclone, then to a channel between an inner shell and the outer shell, and discharged from a lower outlet. The inner shell prevents an upward flow from affecting the flocs, making it possible to achieve reliable separation of the flocs.

Dependent claims

A flocculation cyclone device that collects magnetic flocs, which are obtained by putting a magnetic substance and a flocculant into floating matter in a fluid and flocculating them by centrifugal force and magnetic force, the flocculation cyclone device comprising:

an inverted truncated cone-shaped outer shell that helically rotates fluid containing flocculated flocs;
a cylindrical part disposed in a center portion of the outer shell so as to pass fluid through the outer shell upward;
a dish-shaped inner shell that is installed inside the outer shell and surrounds a lower portion of the cylindrical part;
and
a magnet disposed outside the outer shell in the vicinity of the side surface thereof, wherein
the cylindrical part is connected to the inner shell by a plurality of intermittently arranged fixing members,
a fluid between the cylindrical part and the inner shell is discharged with an upward flow generated in the cylindrical part, while the flocs are guided by the magnet between the outer shell and the inner shell are discharged from a lower end of the outer shell.
