Improving the energy efficiency of Alfa Laval separation equipment
The bowl can be equipped with special power plates or tubes that harness the hydraulic energy to reduce the overall power consumption. Some of the discharge velocity from the liquid leaving the unit is captured and re-directed to contribute to bowl rotation. This reduces the velocity of the discharged liquid, which in turn reduces overall power requirements. The unique Alfa Laval direct drive system automatically controls the conveying speed to ensure optimum solids dryness, irrespective of acceptable variations in the feed flow.
From dewatering heat-coagulated potato protein, maize gluten and wheat starch to protein splitting in starch production, Prodec centrifuge decanters excel in food and starch processing. Their robust design also ensures optimal performance when handling erosive, corrosive and high-temperature slurries in mineral processing, pulp and paper, coal tar and steel industries. In addition, they play a critical role in ethanol and biofuel production, supporting sustainable energy solutions.
Which decanter features make a difference in your industrial separation process?
Available as 2 or 3 phase separation designs, this Alfa Laval water oil separator can be tailored to specific requirements using corrosion resistant materials, enhanced wear protection and effective cleaning options. The bowl and conveying speed, pond depth in the bowl and feed rate are adjustable to improve the performance and operate reliably and efficient.
The Prodec decanter centrifuge comes with an Alfa Laval decanter automation control package as standard, pre-installed and factory-tested to make sure you get the most out of your set-up. It also helps minimize costs for installation, commissioning, operation and maintenance.
3Phase
Separating suspended solids from two liquid phases in one step
Accurate adjustment possibilities and long retention time ensure separation in three distinct fractions in one run. 3Phase separation ensures an accurate and stable interphase level, which is key for coping with variations in feed compositions and flow rates. The unique design creates low agitation, resulting in high clarity in both liquid phases.
DeepPond
Alto rendimiento de separación y eficiencia energética
Al aumentar la profundidad del estanque dentro de la cubeta se crea un mayor volumen, lo que conlleva un mayor tiempo de retención y un mejor rendimiento de separación. El diseño de DeepPond proporciona un alto grado de sequedad de sólidos y un centrado limpio de su centrífuga decantadora, incluso a altos caudales.
VecFlow™
Zona de alimentación giratoria
Una baja turbulencia en el recipiente de la centrífuga decantadora es esencial para un alto rendimiento de separación y un bajo consumo de energía. La zona de alimentación giratoria VecFlow™ le ofrece el máximo rendimiento con una mínima turbulencia.
OilPlus
Extracción máxima de petróleo
Interacción especial entre sólidos y fluidos para obtener la máxima recuperación de petróleo.
FlightGuard
Protección resistente al desgaste para paletas transportadoras
La protección contra el desgaste FlightGuard consiste en baldosas soldadas a la cinta transportadora, lo que proporciona una resistencia robusta al desgaste y un tiempo de actividad prolongado en aplicaciones altamente abrasivas.
How do Alfa Laval centrifuge decanters work?
The decanter centrifuge working principle is based on separation inside a horizontal cylindrical bowl equipped with a screw conveyor. The product is fed into the bowl through a stationary inlet tube and is smoothly accelerated by an inlet rotor. Centrifugal force immediately makes the solids build up on the wall of the bowl, ensuring effective solid-liquid separation.
The conveyor rotates in the same direction as the bowl but at a different speed, moving solids toward the conical end where they exit through the solids discharge openings into the casing. Separation in a water oil separator takes place along the entire length of the cylindrical part of the bowl, and the clarified liquid exits through adjustable outlet tubes.
