Double Motor Frequency Conversion Drive Industrial Decanter Centrifuge Of Sludge Dewatering
Brief introduction of the Double Motor Frequency Conversion Drive Industrial Decanter Centrifuge Of Sludge Dewatering
When solid/liquid mixtures with a high portion of solids need to be separated, decanter centrifuges are the solution of choice. In contrast to chamber filter presses, these solid shell scroll centrifuges or decanters operate continuously. High centrifugal forces separate the finely distributed solid particles from the suspension.
The modular design of our decanters makes them useful in a wide variety of industries throughout the world – from Australia to Zambia. The centrifuges are adapted optimally to the specific application. Applications range from sludge dewatering to classification or wet classification to the sorting of solids.
Operation principle of the industrial sludge dewatering decanter centrifuge
The operating principle of a decanter centrifuge is based on separation via buoyancy. Naturally, a component with a higher density would fall to the bottom of a mixture, while the less dense component would be suspended above it.
A decanter centrifuge increases the rate of settling through the use of continuous rotation, producing a G-force equivalent to between 1000 and 4000 G's.
This reduces the settling time of the components by a large magnitude, whereby mixtures previously having to take hours to settle can be settled in a matter of seconds using a decanter centrifuge. This form of separation enables more rapid and controllable results.
How does it work -- industrial sludge dewatering decanter centrifuge ?
The feed product is pumped into the decanter centrifuge through the inlet. Feed goes into a horizontal bowl, which rotates. The bowl is composed of a cylindrical part and a conical part. The separation takes place in the cylindrical part of the bowl. The fast rotation generates centrifugal forces up to 4000 x g.
Under these forces, the solid particles with higher density are collected and compacted on the wall of the bowl. A scroll (also screw or screw conveyor) rotates inside the bowl at a slightly different speed. This speed difference is called the differential speed.
This way the scroll is transporting the settled particles along the cylindrical part of the bowl and up to the end conical part of the bowl. At the smallest end of the conical part of the bowl, the dewatered solids leave the bowl via discharge opening. The clarified liquid leaves through a paring disc (or internal centripetal pump).
Advantages of the industrial sludge dewatering decanter centrifuge
01. Decanter centrifuges have a clean appearance and have little to no odour problems.
02. Not only is the device easy to install and fast at starting up and shutting down but also only requires a small area for operation compared to other competitive processes.
03.The decanter centrifuge is versatile as different lengths of the cylindrical bowl section and the cone angle can be selected for different applications.
04.The machine can operate with a higher throughput capacity than smaller machines. This also reduces the number of units required.
05.The device is simple to optimise and operate as it has few major variables and reliable feedback information.
06.The decanter centrifuge has reduced labour costs compared to other processes, as it requires low continuous maintenance and operator attention.
Range of applications:
The main application of decanter centrifuges is to separate large amounts of solids from liquids on a continuous basis. They are also used to wash and dry various solids in industry, such as polystyrene beads, clarify liquids and concentrate solids.
