Abstract:
Disclosed is a sludge processing system having a centrifugal separator which concentrates the sludge and a furnace which heat-treats the concentrated sludge, and allows the automatic control in which the operational condition of the centrifugal separator is set to the optimal condition in accordance with the operational state of the furnace. The control device sets a variable range of a differential speed between the bowl and the screw conveyor of the centrifugal separator, and performs a variable control of the differential speed so that the measurements concentration moisture of the concentration sludge achieves a moisture content requested by the furnace within the variable range, when the measurements concentration moisture of the concentration sludge maintains the moisture content requested by the furnace for a certain period of time being previously set, changes a control value of the centrifugal force.
