摘要： The pressure diffuser incorporates a screen that has a considerable weight that is moved by a connecting rod in a reciprocating manner between an upper and lower position. The connecting rod is maneuvered by a hydraulic cylinder for vertically moving the screen in a first slow stroke concurrent with pulp-flow and moving the screen in a second fast stroke countercurrent to pulp-flow. The pressure diffuser has an inlet defined therein at the bottom of the vessel but the hydraulic cylinder is located at the top of the vessel. This design enables an increased active pressure area in the hydraulic cylinder for the fast stroke of the screen. This reduces the power-rating needed for the hydraulic system.

摘要： The invention relates to a method for supplying washing liquid to a digester (1) for cellulose pulp and a subsequent diffuser washing device (2a, 2b). A high, disturbance-free production capacity can be obtained by using a common feed pump (P1) which, via a main feed line (10), supplies both the diffuser washing device and the digester with washing liquid in parallel. The first pump (P1) establishes a pressure on the washing liquid which is in the interval 2–6 bar, and is preferably 4 bar, while the second pressure level, which is established by the diffuser pump device (P2a, P2b), is in the interval 6–12 bar, but is at least 2 bar higher than the first pressure level, and the third pressure level, which is established by the digester pump (P3), is in the interval 12–25 bar The system becomes self-regulating in the event of any operational disturbances in the flow of washing liquid and, if the pumps are appropriate, a countercurrent flow of washing liquid through the system is essentially maintained.

摘要： The invention relates to a process for continuous cooking of wood chips at elevated pressure and temperature in a vertical digester (1) for production of chemically dissolved pulp. Fiber material and cooking liquor are introduced at the top of the digester and pulp is discharged from the bottom of the digester (1), via a line (8) in which the pulp is maintained at substantially the same pressure level, to a pressurized wash (7). More than 50% of the used cooking liquor (black liquor) which is extracted from the system in total is extracted from the wash filtrate of the pressurized wash. The pressurized wash is regulated so that a high temperature is maintained in the wash filtrate. The extraction is regulated so that a net co-current flow is established at the bottom of the digester.
