Centrifugal Sludge Dewatering Machine Centrifugal Sedimentation Principle and Dehydration Requirements Dec 30, 2017

Centrifugal sludge dewatering machine in the process of using mainly by the differential system, level baffle, drum, screw, level baffle, drive system and control system and other components, the device is mainly the use of its solid-liquid two-phase Density difference, in the role of centrifugal force, which speed up the settlement rate of solid particles to achieve solid-liquid separation.

Centrifugal sludge dewatering machine for the specific separation process for the sludge and flocculant liquid through the inlet pipe is fed into the mixing chamber drum, mixed flocculation is mainly due to high-speed rotation of the rotor and friction resistance, the sludge inside the rotor was Speed up and form a cylindrical liquid ring layer, under the action of centrifugal force, a larger proportion of solid particles settle to the inner wall of the drum to form a mud layer, and then use the relative speed difference between the spiral and the drum to push the solid phase to the cone end of the drum After the liquid level, the sludge is dehydrated and dried, discharged to the slag discharge port, and the supernatant is discharged from the big end of the drum to achieve solid-liquid separation.

Centrifugal sludge dewatering machine is mainly the use of centrifugal sedimentation principle, so that will make the solid-liquid separation, due to the presence of filter, will not cause blockage, and the belt filter to make solid-liquid separation, in order to prevent clogging filter, Water constantly washed.

Centrifugal sludge dewatering machine is suitable for various types of sludge concentration and dehydration when it is used, and its belt machine is also applicable to all kinds of sludge, but for oily, viscous, excess activated sludge need large dosage and difficult to dehydrate, When the feed concentration changes during the dehydration process, the slip and torque of the drum and the screw will be tracked automatically, so no special operation is required. However, when the feed concentration changes with the filter during the dehydration process, the belt speed, Tension, dosage, flushing water pressure needs to be adjusted, operating requirements higher.

Centrifugal sludge dehydrator fine sludge can also be separated from the water, so the dosage of flocculant less, the general mixing sludge dewatering dosage: 1.5kg / t, the sludge recovery rate of 95% , The water content of dehydrated cake is about 60% -85%, while the filter belt can not be woven too densely because of the filter belt. In order to prevent the tiny sludge from leaking, more flocculant needs to be added to make the sludge The formation of larger flocs, the general mixed sludge dewatering dosage is greater than 3kg / L, the sludge recovery rate of 90% or more, after dehydration cake moisture content of about 80%.
