Abstract
Self-delivering digester 100s with self-delivery of accumulated solids are described. A primary waste vessel includes a feeding port for kitchen waste, and an upper output component that connects to a top of the primary waste vessel. The upper output component includes a gas output path from a top of the upper output component, and a floating solids output path that delivers floating solids that overflow from the top of the primary waste vessel to a secondary vessel thereby preventing clogging of the gas output path.
Claims20
A self-delivering digester, comprising:
- a primary waste vessel comprising a feeding port for kitchen waste;
- and
- an upper output component that connects to a top of the primary waste vessel, the upper output component comprising:
- a gas output path from a top of the upper output component;
- and
- a floating solids output path that delivers floating solids that overflow from the top of the primary waste vessel to a secondary vessel;
- and
- an upper collection container that collects secondary vessel floating solids from a top of the secondary vessel, the upper collection container comprising an openable lid that enables removal of the secondary vessel floating solids.
A self-delivering digester, comprising:
- a primary waste vessel comprising a feeding port for kitchen waste;
- and
- an upper output component that connects to a top of the primary waste vessel, the upper output component comprising:
- a gas output path from a top of the upper output component;
- and
- a floating solids output path that delivers floating solids that overflow from the top of the primary waste vessel to a secondary vessel;
- and
- a lower collection container that collects sludge from a bottom of the secondary vessel.
A system, comprising:
- a primary vessel, wherein the primary waste vessel comprises an upper section and a lower section that are connected through a packed bed comprising a u-shaped inlet tube;
- and
- an output component that connects to a top of the primary vessel, the output component comprising:
- a gas output path from a top of the output component;
- and
- a floating solids output path that delivers floating solids that overflow from the top of the primary vessel to a secondary vessel.
