3 phase decanter centrifuge is mainly designed for Solid-liquid-liquid three-phase separation of materials.With our over 10 years of experience in the separation industry, it is the most advanced type machine for 3 phase separation. It is designed for 24 hours continuous and smooth operation throughout the day. It is mainly composed of driving system, decanter bowl, screw conveyor inside the bowl, cover box, skid and VFD control panel.
To ensure that the separation process can take place, the solid phase must be the specifically heaviest phase and the two liquid phases must have different densities.The main difference between the 2 phase decanter and 3 phase decanter is that the 3 phase decanter not only separate the solids but also separate two phase of the liquid.
Product Description
3 PHASE DECANTER WORKING PRINCIPLE
The three-phase decanter centrifuge operation is based on the principle of sedimentation, that is, solid particles with specific liquid weight precipitate in a predetermined time. This principle can also be applied to two immiscible liquids with different specific gravity. When the material enters the high-speed rotating drum, the material rotates synchronously with the drum. Because of the different specific gravity, the centrifugal force is different. The solid particles with the larger specific gravity are subjected to the greatest centrifugal force, followed by the heavy phase liquid (such as water) and the light phase liquid (such as oil). So the centrifugal force is becoming less from outside to inside according to the magnitude of centrifugal force. A concentric solid layer and two liquid layers are formed. Solids are pushed out by the screw conveyor, and liquids are removed from their respective nozzles. Therefore, the application of three-phase decanter centrifuge can not only separate the solid in the material, but also separate the two-phase liquid with different specific gravity in the material, that is, Solid-liquid-liquid separation can be achieved.
Combined Driving Mode
Single Motor Drive: Single motor drive generally adopts a frequency conversion motor + frequency converter to drive the drum and screw at the same time.
The method is simple, the operation is simple, and the manufacturing cost is low. Single motor drive is mainly used for materials with constant solid content, and there is no strict requirement for the water content of the discharged solid phase. Because there is no necessary differential adjustment mechanism, the differential between the drum and the screw can only be realized by changing the gear transmission ratio or changing the drum speed.
Dual Motor Drive: Dual motor drive generally adopts two frequency conversion motors + two frequency converters tocontrol the dynamic rotation of drum and screw respectively.
ln the dual motor drive mode, the differential speed between the drum and the screw is adjusted by simply adjusting the speed of the motor. This driving mode is applied to materials with variable solid content and strict requirements for discharged solid water content.
Hydraulic Drive: The hydraulic drive generally adopts frequency conversion motor + frequency converter + hydraulic motor to drive the drum and screw respectively.
ln the hydraulic drive mode, the differential speed between the drum and the screw can be adjusted by the hydraulic motor. When moving at very low differential speed, its degree and stability are better than other driving methods.When the drum rotates normally, both the drum and the screw operate at a certain constant speed. Once the load of the screw pusher increases, the hydraulic motor will adjust the screw pusher to accelerate the operation to prevent material blockage.When the machine is stopped for cleaning due to material blockage, the hydraulic system can drive the screw pusher independently to improve the cleaning and maintenance efficiency.
Structure And Working Principle
In the three-phase horizontal screw centrifuge, the materials to be separated enter the acceleration chamber of the screw pusher through the feed pipe and then enter the inner wall of the rotating drum at high speed. Due to the different specific gravity of light liquid phase heavy liquid phase insoluble solid phase in the materials, the centrifugal force on the three-phase materials is different, and the insoluble solid phase is settled to the inner wall (outermost) due to the largest centrifuge with the largest specific gravity, Due to the minimum centrifugal force, the light liquid phase is settled farthest (outermost) from the inner wall of the drum. The heavy liquid phase is in the middle. The insoluble solid phase is discharged from the solid phase outlet through the screw pusher with relative differential speed with the drum. The light and heavy liquid phases are separated by different structures in the machine. The heavy liquid phase is discharged through the centripetal pump and the light liquid phase is discharged by gravity, so as to achieve the purpose of three-phase separation of materials.
The light and heavy liquid phases of our three-phase horizontal screw centrifuges are discharged by gravity and centrifugal force respectively, so as to effectively avoid the incomplete separation of materials caused by the mixing of materials. When working, the ordinary three-phase horizontal screw centrifuges often cause incomplete separation due to the unstable components of light and heavy liquid phases, Our three-phase horizontal screw centrifuge can adjust the interface of light and heavy liquid phases according to the changes of material components, so as to achieve the ideal separation effect.

3 PHASE DECANTER ADJUSTABLE SEPARATION
Flexible for different Liquid Phase Proportion
An adjustable impeller discharges the "heavy" liquid phase. Furthermore, the operator can use the adjustable impeller to adjust the pond depth of the heavy liquid without difficulty during ongoing operation. According to the Proportion of two different phase, An adjustment mechanism causes the position of the impeller to change, thus changing the separation line of the liquids. The process engineering results can thus be influenced so as to achieve the required separation result.
Separation Range
A. When the liquid viscosity is small and the solid particle size is large, the specific gravity difference between solid, liquid and liquid is required to be ≥ 0.05g/cm3 (solid weight and liquid light).
B. When the liquid viscosity is small and the specific gravity difference between solid and liquid is large (specific gravity difference ≥ 1g / cm3), the solid particle is required to be ≥ 0.005mm and the specific gravity difference between liquid and liquid is required to be ≥ 0.05g/cm3.
C. When the liquid viscosity is large or the specific gravity of solid-liquid is small and the solid particles are very fine, the separation effect will be affected or even not applicable.
D. When the solid particles are easy to be damaged, the separation effect will also be affected.
