摘要： 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.

摘要： A centrifugal apparatus includes: a bowl including a plurality of projection portions provided in a standing manner at an edge portion of an opening portion, the plurality of projection portions each including a curved surface portion bulging toward a rotation axis; a screw conveyer; a hub forming separate matter discharge ports between the respective circumferentially adjacent projection portions; and wear-resistant sleeves. The wear-resistant sleeves each includes a sleeve body that is formed in an arched shape along the corresponding curved surface portion and covers the curved surface portion; and a claw portion including one end connected to one end portion, in a longitudinal direction perpendicular to the axis direction, of the sleeve body. The claw portion is in contact with an outer surface of the corresponding projection portion and fixed to the outer surface via a detachable tool for fixing, and an insertion opening for inserting the projection portion.

摘要： The object of the present invention is to realize standardization of products of the vertical centrifugal separators so that it is no longer necessary to change the pressure-resistant design specifications of the bearing mechanism depending on the set pressure inside the casing. The vertical centrifugal separator having the bearing mechanism that is disposed in an opening of the casing and rotatably supports the rotary shaft of the bowl passing through the opening. The shaft sealing mechanism is a contactless shaft sealing mechanism.

摘要： A polymer flocculant mixing and dissolving system comprising: a mixing tank (2) in which a solid polymer flocculant is mixed with water used as a solvent; a liquid feed unit (3) for feeding an aqueous solution containing the polymer flocculant from the mixing tank; a regenerative mixer (4A,4B) used to mix and dissolve the polymer flocculant by applying pressure to the aqueous solution containing the polymer flocculant fed from the liquid feed unit while forming a vortex flow; a process channel (61) through which the aqueous solution that has passed through the regenerative mixer is fed to a downstream process; a circulation channel (62) through which the aqueous solution is returned to a position on an upstream side of the liquid feed unit; and a flow rate adjusting unit (6) for adjusting a balance between a flow rate of the aqueous solution flowing through the process channel and a flow rate of the aqueous solution flowing through the circulation channel. The polymer flocculant mixing and dissolving system can stably supply the solution in an amount required in the downstream process.

摘要： A decanter centrifuge that carries out solid-liquid separation by centrifugal force on an object to be processed that is fed into a rotating bowl and designed from a solid and a saturated solution wherein that solid is dissolved, and discharges solid phase components from a solid discharge opening and discharges liquid phase components from a solvent discharge opening thereof by rotationally operating a screw conveyor disposed within the rotating bowl, the decanter centrifuge being provided with a dilution solvent supply unit for supplying, during centrifuging of the object to be processed, dilution solvent that reduces the concentration of the saturated solution to a discharge path, which is a discharge path for saturated solution moving within the rotating bowl, and which is designed closer to the solvent discharge opening side-than a chamber for supplying the object to be processed.

摘要： A centrifuge provided with: a bowl having a plurality of extension lugs formed on an opening rim section at one end of the bowl in the axial direction, the extension lugs being spaced apart from one another in the circumferential direction; a screw conveyer rotatably housed inside the bowl and rotatable at a different rotational speed than the bowl; a hub forming solid discharge ports between circumferentially adjacent pairs of the extension lugs, the hub connecting to the extension lugs and covering an opening of the opening rim section from the axial direction; and a wear-resistant sleeve including a sleeve body and a flange. The sleeve body covers lug inner surfaces of the extension lugs and the flange extends in an arced shape along the opening rim section. The sleeve body is attached with axially extending bolts to the opening rim section at a position that avoids the extension lugs.

摘要： A disc-type centrifuge is configured to use clean water as sealing water to be supplied at high pressure to a sealing mechanism unit. A pump is disposed on a circulation pathway connecting a sealing water tank, in which the sealing water is stored, and the sealing mechanism unit. The sealing water (clean water) is circulated between the sealing water tank and the sealing mechanism unit by the pump. The pump is connected to the drive shaft of a motor that supplies a driving force to a rotating shaft and bowl and is configured so that the pump is operated by receiving the driving force of the motor.
