Operational requirements and main advantages of continuous decanter centrifuges
The continuous decanter centrifuge is a new type of equipment. In the process of working, the principle is mainly to use the solid-liquid specific gravity difference, and rely on the centrifugal force field to expand it several thousand times, and the solid phase is settled under the action of centrifugal force. The solid-liquid separation is achieved, and the body is separately discharged under the action of a special mechanism. When centrifugal filtration is easy to block the filter medium due to solid particles and the filtration resistance is too large or the fine particles are lost too much, the filter centrifuge can not achieve the ideal separation effect. At this time, the decanter centrifuge has a filter type that is incomparable. Advantage. By using the principle of centrifugal sedimentation, solid phase particles having a small particle size can be separated from the liquid phase.
The suspension of the continuous decanter centrifuge enters the drum from the feeding tube, and the solid phase particles are accelerated by the centrifugal force to the inner wall of the drum under the action of the centrifugal force field, and the settled particles are pushed by the auger blades, from the straight section The settling zone is discharged through the (cone section) drying zone to the solid phase outlet; the clarified liquid phase overflows from the overflow orifice. Thereby achieving automatic and continuous separation of solid and liquid phases.
The main advantage of the continuous decanter centrifuge is automatic and continuous operation. It can be operated for a long time and easy to maintain during operation. It can work under pressure and low temperature to a certain extent. Its single machine production capacity is large, and its processing capacity is 0.4 to a certain extent. ~60m3/h Particle size 2 μm~5mm, solid phase concentration 1%~50%, solid-liquid density difference more than 0.05g/cm3. The separation factor is high, the drum length and diameter are larger than the design range, and the depth of the drum liquid pool is adjustable. Therefore, it has strong applicability and wide application range.
