| description | The invention discloses a preparation method of bamboo pulp. The preparation method comprises the steps of material preparation and pot loading, vapor-liquid composite pre-hydrolysis, acid discharge, alkali boiling and blowing. According to the bamboo pulp preparation method, steam pre-hydrolysis and high-temperature hot water pre-hydrolysis are alternately adopted for pre-hydrolysis of the bamboo chips, and the steam pre-hydrolysis and the high-temperature hot water pre-hydrolysis are continuously transited, so that the reaction uniformity of the bamboo chips can be obviously improved, and meanwhile, the defects of slow temperature rise and high energy consumption of a traditional full-liquid-phase water pre-hydrolysis process are overcome to a certain extent; the production efficiency is improved, a DDS energy-saving replacement cooking process and segmented alkali addition are adopted, the operation procedure is simplified, and the reaction activity of the bamboo pulp is improved, so that the yield of the |
