2 Phase Separation Industrial Disc Stack Centrifuge Separator

Product Description

The disc stack separator is also called disc separator. It is a device that rapidly separates solid and liquid through high-speed centrifugal force. The alias is also called disc centrifuge or conical plate centrifuge, which belongs to a type of vertical centrifuge. The disc separator is driven by a motor and rotates at high speed. In the bowl of the disc separator, there is a set of disc-shaped parts nested with each other-commonly known as discs. There is a small gap among the discs, which are used for centrifugal sedimentation of materials. The suspension (or emulsion) to be processed enters the bowl of the disc separator through the feed pipe. When the suspension (or emulsion) flows through the gap between the discs, the solid particles (or droplets) settle on the disc under the action of the centrifuge to form a sediment (or liquid layer). The sludge slides along the surface of the disc to separate from the disc and accumulates in the inner bowl where the diameter is large, and the separated liquid is discharged from the bowl through the liquid outlet. For the 3-phase disc separator, there are two centripetal pumps inside, which can discharge the two immiscible liquid phases having difference densities. The role of the discs in the disc separator is to shorten the settling distance of solid particles (or droplets) and expand the effective settling area of the bowl so as to greatly improve the production capacity of the disc separator. The solids accumulated in the bowl can be discharged through the automatic slag discharge mechanism without stopping the machine. By using the disc separator, solid-liquid-liquid 3-phase separation or solid-liquid separation is realized.

  The 2 phase disc stack separator is used to separate the fine particles from the liquid and discharge clarified liquid. Compared with decanter centrifuge, the G force of 2 phase disc stack separator is much higher than decanter centrifuge. The disc stack separator G force is up 12000g. Generally, the G force of the decanter centrifuge is about 3000G. The high speed and G force makes the disc stack separator to produce high clarified liquid. However, the materials separated by disc separator should not have high solid content or big particles. Usually the particles content should be less than 3%, it's better to be 1%. Therefore, in some application, pre-treatment will be carried out by decanter centrifuge or other separation equipment, and then clarification and separation will be carried out in the 2 phase disc stack separator. The 2 phase disc stack separator is widely used in vegetable oil clarification, biological and chemical pharmaceutical industry, dairy and beverage industry, biofuel and marine oil clarification, etc.
  The material to be clarified enters the bowl through a feed pipe. In the distribution cabinet of the disc separator, the material is smoothly accelerated until it is synchronized with the speed of the rotary bowl. The disc stack in the rotating cylinder divides the material into many thin layers, forming a large area of clarification area. The high-speed centrifugal force makes the solid slag separated from the liquid in the disc stack deposit into the solid slag collection cavity at the edge of the bowl. The self-discharging 2 phase disc separator can be adjusted according to the material.
  3 phase disc stack separator is a high-speed, stable, sealed, efficient, and automatic slag discharge 3 phase separation equipment. It is widely used for liquid, liquid, solid 3-phase separation or liquid-liquid separation. The 2-phase solid-liquid separation disc separator has only one liquid discharge port and one slag discharge port, while the 3-phase disc separator has two liquid discharge ports and one slag discharge port, which can separate two liquids with different specific gravity at the same time. It can also discharge solid phase materials. Compared with the 3 phase decanter centrifuge, the 3 phase disc separator has larger rotation speed and G force. The 3 phase decanter centrifuge usually has a separation factor of about 3000G, while the 3 phase disc stack separator G force is up to 12000G. Therefore, the 3 phase disc separator can more thoroughly separate liquids with different specific gravity and the liquid phase discharged is more clarified. However, compared to 3 phase decanter centrifuges, 3 phase disc separator is more used to separate materials containing fine particles, with less solids content. So before entering the 3 phase disc separator, the material can separated by the decanter centrifuge for pre-stage separation to reduce the solids content and remove big particles.

The separated material enters into the heart of the machine, that is, the inside of the bowl. Under the action of strong centrifugal force, the material passes through a set of disc bundle separation intervals. With the neutral holes of the disc as the interface, the liquid with larger specific gravity moves along the disc wall towards the outside the neutral hole, where heavy slag accumulates in the sediment area, and the heavy phase liquid flows upward to the centripetal pump; the lighter liquid with a smaller specific gravity moves along the disc wall into the neutral hole and converges to the lower centrifugal pump. The light and heavy liquid phases are discharged by the lower centrifugal pump and the upper centripetal pump respectively; the heavy slag is regularly discharged; continuous production is implemented.
