composition:

The sludge dewatering system consists of five parts:

(1) Sludge feeding system, (2) Flocculant dosing system, 3) Thickening and dewatering system,

(4) Mud cake delivery system, (5) Electronic control device of sets of system;

Descripition:

Decanter centrifuge is one of our main products. Utilizing our technological advantages, we have developed centrifuges with varied structures to

cater for different sludge dewatering requirements.

In the field of environmental protection, we use the automatic control system that boasts high length-diameter ratio, high speed, small differential

speed. High length-diameter ratio increases the material clarification and dewatering time inside the machine; high speed generates great

centrifugal force, leading to thorough dehydration of material; small differential speed reduces spiral stirring the materials, increases the

dewatering time, therefore improves the separation in sludge thickening, dewatering and clarification, which can obtain drier solid residue and

clearer clarification liquid compared to other decanter centrifuges; in order to maintain the best dewatering effect, the operation parameters are

subject to automatical regulation with the amount and quality of sludge entering into the centrifuge, which ensures normal operation of the

machine and stable water content in the discharged sludge. If the condition of sludge entering the machine changes greatly, beyond the

regulation capacity of the machine or the machine itself fails, the machine will shut down automatically and alarm.

Feature:

Our centrifugal sludge dewatering machines can achieve sludge thickening, sludge dewatering as well as thickening and dewatering integration.

Dewatering and thickening of sludge form municipal and industrial waste water, such as : municipal sludge, paper mill sludge, starch sludge, steel

mill sludge, printing and dyeing mill sludge, water works sludge, pharmaceutical sludge, PVC sludge, sewage desulfurization sludge, grain

stillage, power plant ash sludge, dairy sludge, beer sludge, drilling mud, electroplating liquid, fermented liquid manure, oil refining sludge, soap

sludge, leather sludge, and other types of sludge.

Working Principle:

Basic principle of horizontalscroll discharge centrifuges (namely decanter centrifuges): the light liquid, heavy liquid and solid (dregs) in the mixed

liquid (suspension) have different densities and are immiscible, and any two or three phases therein are then under different centrifugal forces in

the centrifugal force field, resulting in different settling velocities, then achieving thepurpose of separation, layering or settling the

solid-phase particles in the liquid.

After entering into the high-speed turning drum,the solid-phase particles in the mixed liquid run and settle on the drum wallunder the action of

greatest centrifugal force; the light liquid settles at the innermost place of the drum under minimum centrifugal force; and the heavy liquid settles

in the middle (this phase exists in case of three-phase separation or does not exists in case of two phases); same as the drum’s turning direction,

a screw feeder also turns at a high speed, and a constant speed difference is generated by the differential mechanism; the solid-phase particles

settled on the drum wall are then fed by the screw feeder to the solid outletof the drum, and the light phase and heavy phase (this phase exists in

case of three-phase separation or does not exists in case of two phases) are then separated out of different outlets. When used for two-phase

separation, the machine is called two-phase decanter centrifuge (also called horizontal scroll centrifuge), and the machine used for three-phase

separation is called three-phase decanter centrifuge. In our decanter centrifuges, the light liquid is exhausted by gravity force, and the heavy

liquid is discharged by the centrifugal force.
