Method for cleaning contaminated fibers of waste paper, involves moving fibers to be cleaned with liquid, and bringing together solid-fluid mixture with air-liquid mixture

摘要

The method involves moving the fibers to be cleaned with liquid, and bringing together a solid-fluid mixture is with an air-liquid mixture, where the combining of the air-liquid mixture with the solid-liquid mixture takes place with widely differing flow speeds. The dissolved contaminated particles settle on the air bubble from the air-liquid mixture. The mixture of a fractionation is subjected to separation of the fiber portion. An independent claim is also included for an arrangement for cleaning contaminated fibers.
