3 Phase Liquid Solid Separation Decanter Centrifuge , Centrifugal Machine

Description

Tricanter centrifuge, also known as a three-phase decanter centrifuge, is a specialized type of centrifuge used for the separation of three different phases of a mixture. It is commonly employed in industries such as oil and gas, chemical, food processing, and wastewater treatment.

The tricanter centrifuge utilizes the principle of sedimentation and centrifugal force to separate a mixture into three distinct phases: solids, liquid, and liquid. It is particularly effective in applications where the separation of two immiscible liquids and solids is required.

The centrifuge consists of a horizontally arranged cylindrical bowl with a screw conveyor inside. The mixture is fed into the bowl, and due to the high rotational speed, the centrifugal force causes the heavier solids to settle at the bowl wall, forming a sediment layer. The lighter liquid phase forms an intermediate layer, while the second liquid phase, which may have a different density or composition, forms the innermost layer.

The screw conveyor inside the tricanter centrifuge rotates at a different speed than the bowl, which helps to transport the separated solids out of the bowl while simultaneously discharging the separated liquid phases through separate outlets. This allows for continuous and simultaneous separation of the three phases.

Tricanter centrifuges offer several advantages in industrial applications. They provide high separation efficiency, allowing for the recovery of valuable solids or liquids from the mixture. They are also capable of handling a wide range of feed materials with varying solid and liquid concentrations. Additionally, tricanter centrifuges can operate continuously, enabling efficient and uninterrupted processing.

Structural characteristics

• Structure: this machine is 3-phase horizontal screw discharge sedimental centrifuge.It consists
• of the drum, big and small end cover shaft, screw, gearbox, base, hood, vibration absorber,etc. Unde the centrifugal force, the liquid-liquidsolid separation will be realized continuously.
• Discharging type: the dewatered solid cake is pushed out of the drum by the discharging
• screw, and fall under the gravity. The separated light liquid phase and heavy liquid phase is
• discharged from the drum under centrifugal force, and then discharge under gravity.
• Adopt big length-diameter ratio and high rotating speed. Big length-diameter ratio can prolong the time of clarifying and dewatering. High rotating speed has large centrifugal force field, which can improve the separating effect.
• The adjustable wire plate is installed at the big end of the dru m, to adjust the liquid depth of the liquid layer inside the drum, and ensure the separating effect.
• Adopt double variable frequency start, the drum can be controlled steplessly.
• We use SKF brand for the main bearing, and adopt high quality grease for lubrication.
• Wearable technology: replaceable wearable hard alloy sleeve is mounted at the solid discharging port,to improve the durability, and prolong the service life.
• Drum and big and small end cover shaft is DSS2205, screw is anti-corrosion SS316 with hight quality.
• Precise dynamic balance check is done to the drum and screw, that makes less vibration, so that the machine can work for a long time. The operation is safe and reliable.
