A Gas Acuated Mixing System

摘要

A gas actuated mixing system for viscous fluids comprising a container 1 in which a viscous fluid 2 may be held, at least one gas pipe 6 having an outlet 8 within the container 1 through which gas 9 is introducible into the container 1 and a moveable carrier arm 4 upon which the one or more gas pipe outlets 8 are mounted so that the movement of the carrier arm 4 causes the position at which each outlet 8 introduces gas 9 into the container 1 to vary over time. A method of mixing viscous fluids within an anaerobic digester is also discloses where by the fluid is mixed by introducing gas via a gas pipe which is attached to a moveable arm.
