| 摘要 |
The invention concerns an integrated cellulose foil and fibre manufacturing works according to the amine oxide process. The works substantially comprise a cellulose production plant, a mixer (B, B') for producing a low-consistency cellulose suspension in an aqueous amine oxide solution, and a device (C) for concentrating the low-consistency cellulose suspension. In device (C), the cellulose suspension is mechanically spread into a layer on a heating surface, is heated and conveyed on said heating surface while being intensively mixed and evaporated, until a predetermined amount of water evaporates and a concentrated cellulose suspension is obtained. In a device (D), the concentrated cellulose suspension obtained in device (C) is converted into a mouldable cellulose solution and in a moulding device connected to device (D), the moulding cellulose solution is transformed into cellulose foils or fibres. |
