Solid-wall scroll centrifuge with front wall with discharge opening having a weir edge and an energy recovery device defining a discharge pipe on the outside of the front wall and in front of the discharge opening having the weir edge

A solid-bowl screw centrifuge (10) having a centrifuge drum (12) that can rotate about a longitudinal axis (18) during operation, the centrifuge drum (12) having a front wall (14) with at least one discharge opening (16) for discharge of clarified product (24) out of the centrifuge drum (12) a weir gate (20) defining a plate attached to the front wall (14) and having a weir edge (22) delimiting the discharge opening (16) toward the outside radially, and an energy recovery device (28;

• 42) for recovering energy from the clarified discharged product (24), the energy recovery device (42) defining a discharge pipe (44) disposed outside axially on the weir gate (20) and through which the clarified product (24) passes as the clarified product (24) flows out, the discharge pipe (44) of the energy recovery device (42) being situated on the outside of the front wall (14) and directly in front of the discharge opening (16) that has the weir edge (22) such that the discharge pipe (44) extends circumferentially completely across the opening and at a position spaced axially outward from the opening.
