Disk stack centrifuge alfa laval

A centrifugal pump creates a pressure to discharge the clear liquid from the centrifuge. The centrifuge separates fuel from methanol or water to convert oils from cenrifuge materials such as rape seed into diesel fuel. Conical plate centrifuge can be used to remove watersalts and solids to condition fuels for gas turbine.

The steeper the cone angle, the greater the G-force produced to clear the solids off the wall of the cone. By monitoring the turbidity of centrate, further fine-tuning can be made. In a nozzle disc bowl, centrate solid output or effluent liquid can be discharged by centripetal pump or paring pump. This is advantageous in reducing the energy of the discharge stream, allows air contact as well as reduces foaming especially when liquid has dissolved protein.

There are many factors affecting process design. Furthermore, processes would be modified in accordance to production, market and environmental demands. A heuristic method available to help design separation process conical plate centrifuge is called Douglas methodology. Douglas methodology uses a three level hierarchical systematic procedure where heuristics can be applied.

The three level process designs are:. Modification of a specific design in accordance to the heuristics rule of thumb for a particular process is one of the effective methods to be applied. Possible heuristics that can be used when designing certain parts of the conical plate centrifuge are:. Conical plate centrifuge produces waste sludge which needs to be treated before it can be disposed.

The treatment for sludge is thickening, dewatering, digestion, drying and destruction, which can act as a post treatment to the conical plate centrifugation process. Further elaboration on these post treatment are:. Sludge thickening by gravitational settling and dynamic is used to minimize the volume of sludge. Feed with a content of 0. This in return helps optimize the following steps by reducing the size of structure and operating costs.

Sludge thickening using centrifugal force is amongst the most common process used. There are two types of centrifuge designed for sludge thickening and both methods depends on the same solid-liquid separation principal. The first method is " solid bowl centrifuge ", a horizontally-arranged helical screw that admits sludge, removes solid in a countercurrent fashion while allowing liquids to pass through.

The moving shaft consists of a set of helical scrolls which push the solid waste against the flow of incoming sludge. As solid content starts to build up, it will become too heavy and then drops down to a collection bin. A video illustrates this process. Centrifuge design depends mostly on solid throughput criteria and solids flux. Sludge dewatering can be achieved by electro-osmosis or centrifugation process.

Prior to dewatering, the thickened sludge is first conditioned. This is to increase the particle size and break the cohesion between the matter and the water, for better dewatering process. The objective of digestion is to reduce sludge quantity, increase sludge dryness and stabilization of sludge. Furthermore, it provides valuation in green energy by producing biogas.

The condition for digestion depends on the quantity and nature of sludge. Sludge drying is necessary to remove remaining water available due to mechanical limitation during sludge dewatering. The thermal drying process is affected by the specific behaviour depends on the dryness to be reached of the sludge. In sludge destruction, all the organic matter present in the sludge is destroyed and during destruction, vapour and electricity is generated.

High separation efficiency of a centrifuge is the result of the combination of centrifugal force and built in pack plate usually a conical disc plate. Therefore, new development usually emphasize on these two areas. A new semi-hermetic centrifuge was designed so that the feed pressure entering the system can be as low as possible by keeping the outlets open, which reduces the pressure drop across the separator.

The stationary paring disc installed at the outlet also allows the process to be operated at low pressure. Another advantage of this design is it produces low noise level due to the rubber -damped assembly, jacketed frame and an outer bowl. Another recent development to the conical plate centrifuge is in sludge dewatering.

With a wide range of design variants available to change particular designs to fit different applications, baffles have been fitted at the solid discharge end of the decanter.

The water and the heavier solids are forced towards the bowl wall where the solids accumulate and the water proceeds over the top disc 4 to an open outlet 5 clarifier version. The light phase moves towards the center and leaves the bowl through a paring disc 6. The machine needs to be stopped at intervals for manual removal of the solids.

The bowl is mounted on a vertical spindle 7 driven by a horizontally mounted motor, via a worm gear. Click here to contact us for application specific details or call our technical sales team at Tell Us About Your Application. What is an Centrifugal Separator?
