Abstract
1. Способ сушки целлюлозы, содержащий следующие этапы:- обеспечение целлюлозы, содержащей целлюлозные волокна;- подведение целлюлозы к проволочной сетке;- обезвоживание целлюлозы при помощи отсасывающего барабана, при этом отсасывающий барабан имеет открытую площадь поверхности более 60% и толщину оболочки более 50 мм.2. Способ по п.1, в котором отсасывающий барабан содержит ракельный нож.3. Способ по п.2, в котором ракельный нож представляет собой воздушный ракель.4. Способ по любому из предшествующих пунктов, в котором сухое содержимое целлюлозы составляет 15-30% от веса после прохождения через отсасывающий барабан.5. Отсасывающий барабан для сушки целлюлозы, при этом отсасывающий барабан имеет открытую площадь поверхности более 60% и толщину оболочки более 50 мм.6. Отсасывающий барабан по п.5, при этом отсасывающий барабан содержит ракельный нож.7. Отсасывающий барабан по п.6, в котором ракельный нож представляет собой воздушный ракель.1. A method of drying cellulose, comprising the following steps: - providing cellulose containing cellulose fibers; - feeding cellulose to a wire mesh; - dewatering the pulp using a suction drum, while the suction drum has an open surface area of more than 60% and a shell thickness of more than 50 mm .2. The method according to claim 1, wherein the suction drum comprises a doctor blade. The method of claim 2, wherein the doctor blade is an air knife. A method according to any one of the preceding claims, wherein the dry pulp content is 15-30% by weight after passing through the suction drum. A suction drum for drying cellulose, while the suction drum has an open surface area of more than 60% and a shell thickness of more than 50 mm. 6. The suction drum according to claim 5, wherein the suction drum comprises a doctor blade. The suction drum according to claim 6, in which the doctor blade is an air doctor blade.
