Forward or reverse hydrocyclone systems and methods |
摘要 |
Hydrocyclone cleaning systems and methods remove contaminants from a suspension of papermaking stock. A subsystem (10) employs forward cleaners for removing heavy contaminants while a subsystem (12) is fed directly from subsystem (10) and removes lightweight contaminants. The subsystem (12) also includes a through-flow cleaner which receives the rejects flow from a primary reverse flow cleaner and both systems are connected to a common surge tank arrangement (15). Both subsystems operate at low consistencies or high efficiency while the primary through-flow cleaner of subsystem (12) provides a system output having a consistency approximately twice as high as that of the input so that the overall operation operates both as a stock cleaner and a stock thickener. |
