Decanter centrifuges - structure and operation
Decanter centrifuges, or decanters, are sedimentation centrifuges without perforated baffles that operate continuously. Like separators, thanks to the centrifugal force they can separate two liquids of different densities. However, they are most often used to separate mixtures with a high content of fine solids. Both of these tasks can be met at once by three-phase centrifuges, also known as tricanters.
Decanters usually have a horizontal, cylindrical-conical drum with a slower rotating scraper screw in the center. Due to the faster rotation of the drum, the solid material settles on the drum shell. The screw then moves it to the conical part of the decanter, where it is ejected through the outlet openings. The liquid, in turn, flows out of a separate opening.
Applications of industrial decanters
Sedimentation centrifuges without partitions are used, among others, in:
Food processing (eg production of fruit juices, vegetable oils and animal fats, dairy products, coffee and tea);
- Petrochemical (eg refining and dewatering processes, oil well drilling);
- Chemical industry (eg bleaching agents, acids, fertilizers);
- Manufacture of thermoplastics;
- Processing of minerals;
- Treatment of water and municipal wastewater.
