Product Description

Shenzhou Industrial separation centrifuge machine for algae harvesting

Harvesting algae cultures with more efficiently
algae are all-purpose: algae is suitable as raw materials for food, biofuels, pharmaceuticals, cosmetics and more. In order to optimize the yield of raw materials, manufacturers need state-of-the-art harvesting technology. 

Due to their positive attributes, algae are increasingly used in coal production to reduce CO2 emissions and in sewage treatment plants to reduce high nitrogen and phosphor levels. This green bioresource grows in culture ponds or in photobioreactors. During the harvesting, algae are separated from their culture substrate and processed further to become a high-quality concentrate. The harvesting technology used has a decisive influence on the efficiency of the overall process: The aim is to keep both the investment costs and the operating costs for energy, water, etc. as low as possible. At the same time, for optimal processing, the separated algae concentrate should have as high a dry matter content as possible.

 

Customer Benefits

Algae harvesting with the Shenzhou Separator

The algae suspension flows from the photobioreactor directly into the Shenzhou Separator. Then the distributor gently accelerates the suspension to full speed. Due to the high centrifugal force of up to 12,000 g, the separator dewaters the algae suspension producing an algae concentrate with creamy consistency. Thus making the algae concentrate ideal for further processing. Small to medium-sized plant benefit in particular from the low investment and low operating costs of the single-stage process.

• up to 25 percent lower investment costs
• lower costs for further processing or drying due to a very high-quality algae concentrate
• suitable for medium and small businesses

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.

Basic equipment

Concentrator or purifier parts, inlet and outlet devices, revolution counter, set of erosion-protective parts ,illuminated sight glass box for light phase outlet , vibration switch , vibration-isolating base plate , flange motor, set of tool and standard set of spare.

Optional extras

Started equipment, frequency converter, discharge control panel, standard set of fittings, set of CIP valves and fittings and serviceability package for online viewing of separator status

 Algae harvesting with the Decanter centrifuge

Algae harvesting with the decanter centrifuge is a two-stage process that is ideal for larger operations: The algae suspension from the photobioreactor is initially pre-concentrated. The algae concentrate then flows on into the Shenzhou decanter centrifuge, where the cell harvesting takes place. The decanter centrifuge dewaters the algae concentrate to a compact cake with 22 to 25 percent dry substance content. Only this special decanter centrifuge is capable of thickening the fine and soft algae cells in such an efficient way.

The pre-concentration in the two-stage process saves energy when compared with single-stage processes. The more water that is separated beforehand, the less the centrifuge has to separate.

• up to 60 percent lower operating costs (e.g. energy)
• up to 25 percent lower investment costs
• 22 to 25 percent high dry solids content for optimum further processing

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.
