Hydrocyclone assembly, for cleaning and degassing a paper fiber suspension, has a common degassing chamber for all the hydrocyclones to take the screened stock

摘要

The hydrocyclone assembly, for cleaning and degassing fiber suspensions, has a number of hydrocyclones (1) each with a feed connection (2) and a connection (3) for screened stock and a reject connection (4). A distributor feeds and extracts liquids, and a underpressure chamber extracts the gas. At least three hydrocylones are formed into a group, and all the screened stock connections open into a common degassing chamber (7), with a connection (8) for underpressure. The degassing chamber has an overflow (14), to set the liquid level (9).
