Abstract
A bin system and a char recovery unit are provided with: a bin for storing char; three char discharge lines placed at the predetermined slope angle for causing the char to fall with the force of gravity so as to discharge the char into the bin; four switching lines placed at the predetermined slope angle for causing the char to fall with the force of gravity so as to feed the char stored in the bin; and assist gas feed units as assist devices for assisting the flow of the char that falls with the force of gravity through the char discharge lines. This allows for equipment downsizing.
Claims14
A bin system comprising:
- a container for gathering or storing powder;
- a plurality of powder discharge lines for causing the powder to fall with the force of gravity so as to discharge the powder into the container, each of the plurality of powder discharge lines including:
- a first linear section placed vertically;
- a second linear section placed vertically;
- and
- a slope section that couples a lower end of the first linear section and an upper end of the second linear section to each other, the slope section being placed so as to slope at a predetermined angle;
- a plurality of powder feed lines placed at a predetermined slope angle, for causing the powder to fall with the force of gravity so as to feed the powder gathered or stored in the container;
- and
- an assist device for assisting flow of the powder that falls with the force of gravity through the plurality of powder discharge lines, wherein
- the assist device includes an assist gas feed device for feeding inert gas in a direction of flow of the powder,
- the assist gas feed device includes:
- an assist gas feed unit including a gas feed pipe through which the inert gas is fed;
- and
- an assist gas discharge unit including:
- a gas discharge pipe through which the inert gas that corresponds to a volume of the powder that has moved is discharged;
- and
- a gas recovery unit that discharges the inert gas contained inside from a rear portion of a downstream end of the slope section to the gas discharge pipe.
