Apparatus and process for treating waste

摘要

Solid waste to be treated is introduced into the interior of a rotary autoclave that is downwardly inclined towards its discharge end and has a door at the discharge end. Steam is injected through said door via a plenum chamber in the door so that water and steam pass through a one-way device and then directly into the interior of the autoclave. The one-way device prevents the solid waste from entering the plenum chamber from the interior of the autoclave. The plenum chamber is defined between a region of the door and a plate secured to the door at a small spacing inwardly of the door. The outlet is defined in the plate and the one one-way device is fitted to the outlet.
