摘　　要：为解决原料结构变化引起的杨木漂白化学机械浆生产线能耗过高,成浆纤维束含量较大的问题,对该生产工艺系统进行了流程调整和设备升级改造。完成改造后,新的生产工艺能够稳定运行,并且达到预设的能耗和质量指标。其中吨浆能耗相比改造前降低了21.42%,成浆纤维束含量由0.10-0.18%降至0.02-0.08%,同时改善了成浆的各项强度指标。该项目的成功为解决化机浆生产线适应原料变化问题提供了有效解决方案。A poplar bleached chemi-thermo-mechanical(BCTMP)pulp line was updated,The updated line was operated stably and refining energy consumption and quality indicators was achieved.The refining energy consumption and shive content of pulps,were decreased significantly.Refining energy consumption was reduced by 21.42%,and the shive content reduced from 0.10-0.18%to 0.02-0.08%,physical strength of pulp improved accordingly.The success of this project provides a new route for some weak points in current BCTMP line because of varieties of wood chips.
