Product Description

Product Description

3-Phase Disc Bowl Centrifuge Separator for Fuel, Waste Oil, and Fat with Environmental Protection and Energy-Saving Features

The disc separator is specially used for the two-phase and three- phase separation. The two-phase separation is to separate the suspended solid from liquid or two liquids which have the different specific gravity and are immiscible. The three-phase separation is to separate the two immiscible liquid phases and a phase of solid at the same time.

1. Liquid solid separation (i.e. separation of bottom concentration suspension), which is called clarification operation, that is two-phase separation.

2. Liquid-liquid separation (or liquid-liquid-solid) separation (i.e., the separation of emulsion) is called separation operation,

that is three-phase separation.

 

Inside the drum is a set of disc-shaped parts, which are nested and folded together. There is a small gap between the discs. The suspension (or emulsion) is added to the drum by the feed pipe at the center of the drum. When the suspension (or emulsion) flows through the gap between the discs, the solid particles (or droplets) settle on the discs under the action of the centrifuge to form sediment (or liquid layer). The sediment slides along the surface of the disc and separates from the disc and accumulates in the place with the largest inner diameter of the drum. The separated liquid is discharged from the outlet of the drum.

The function of the disc is to shorten the settling distance of solid particles (or droplets) and expand the settling area of the drum. The disc installed in the drum greatly improves the production capacity of the separator. The solid accumulated in the drum shall be removed manually after the separator is shut down, or discharged from the drum without shut down through the slag removal mechanism.

Biodiesel is a clean and renewable energy. It is the reborn fuel and excellent substitute of petroleum diesel. Biodiesel is made by ester exchange process which raw material bases on plant oil crops, wild plants and engineering microalgae type aquatic plants fats as well as animal fats, food waste oil, etc.

 

Biodiesel also is a typical "green energy", so develop the bio-diesel has an important strategic significance in continuable economic development, promote alternative energy, reduce environment pressure and control urban air pollution.

Centrifuge machine Standard design

The machine consists of a frame that has a horizontal drive shaft with clutch and brake, worm gear , lubricating oil bath and vertical bowl spindle in the lower part.

The bowl is mounted on top of the spindle in the lower part. The bowl is mounted on top of the spindle , inside the space formed by the upper parts of the frame , the ring solid cover, the collecting cover, and frame hood . The feed and liquid discharge system , including the paring disc pump for the heavy phase, also rests on this structure. All parts in contact with the process liquid are made of stainless steel. The bowl is of the solid-ejecting disc type with hydraulic operating system. The electric motor is of the variable frequency drive type or of controlled-torque type.

Operating principles

Separation takes place inside a rotating bowl. The feed is introduced to the rotating centrifuge bowl from the top via a stationary inlet pipe (1),and is accelerated in the distributor(2),which was specially designed to ensure smooth acceleration of the feed liquid(4). Leaving the distributor, the feed enters the disc stack(3). The separation into liquid-liquid-solid takes place between the discs, with the oil phase moving through the disc stack to the centre. When it reaches the centre, it is discharged through hole (5) and ejected into the collecting frame. The water and heavy solid separated from the oil move to the periphery, and the water flows via channels in the top disc(6) to the paring chamber, where it is pumped out of the rotor by means of a built-in paring disc(7).During purification, hot water is fed into the inlet of the bowl before the process liquid is introduced. The water forms a seal around the outer edge of the top disc. The solid collect in the periphery where they are discharged intermittently via the centrifuge cyclone. The solid are discharged by means of a hydraulic system, which forces the sliding bowl bottom(8)to drop down at preset suitable intervals, thus opening the solid ports at the bowl periphery
How it works

the disc centrifuge separates solids and one or two liquid phases from each other in one single continuous process, using extremely high centrifugal forces. When the denser solids are subjected to such forces, they are forced outwards against the rotating bowl wall, while the less dense liquid phases form concentric inner layers. The area where these two different liquid phases meet is called the interface position. This can be easily varied in order to ensure that the separation takes place with maximum efficiency. Inserting special plates (the "disc stack") provides additional surface settling area, which contributes to speeding up the separation process dramatically. It is the particular configuration, shape and design of these plates that make it possible for a disc stack centrifuge to undertake the continuous separation of a wide range of different solids from either one or two liquids. The concentrated solids phase formed by the particles can be removed continuously, intermittently or manually, depending on centrifuge type and the amount of solids involved in the specific application.
