摘要
国内某企业对杨木BCTMP生产线进行了流程调整和设备升级改造,强化了预浸渍段的机械处理和药液渗透扩散作用。完成改造后,新系统运行稳定,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%,纸浆的各项强度指标均有改善,为解决国内大部分化机浆生产线由于原料变化而存在的共性问题提供了有效解决方案。
A poplar bleached chemi-thermo-mechanical(BCTMP)pulp line was updated,which strengthened the mechanical treatment of the prepreg section and the penetration and diffusion of liquid medicine.The updated line was operated stably with the refining energy consumption 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.It provided an effective solution to solve the common problems of most domestic chemical mechanical pulp production lines due to the change of raw materials.
