年产15万吨牛皮挂面箱纸板制浆造纸综合工厂设计重点：日产450吨牛皮挂面箱纸板打浆、流送系统工艺设计

摘 要：本设计以AOCC为主要原料，经过制浆车间的纤维分级处理分离成短纤维和长纤维，分别作为成纸的芯层浆料和底层浆料，配以未漂硫酸盐针叶木浆板作为面层浆料，不仅使成纸具有合理的物理结构达到成品的质量要求，还合理的利用了纤维资源。基于此考虑，设计的流送系统也是三层独立上浆的，并选用国内外先进的设备，以满足挂面纸板的质量要求和高速纸机的顺利运行。本设计的内容包括浆水平衡计算图绘制、设备选型及计算、车间设备布置图、设备立面图、工艺流程图及全厂总平面图的绘制。通过对打浆和流送系统的工艺设计，系统的掌握纸机生产的工艺技术，并初步掌握工艺设计的程序和工作方法。

150kT/a kraft liner box board Comprehensive Mill of Pulping and Papermaking
Focal:The Approach System of Papermaking Workshop Section of Liner Board is Which Output is 450 per Day
ABSTRACT：AOCC in the design of the main raw material, after the fiber grade pulp processing plant was separated into short fibers and long fibers, respectively, as the core into a paper pulp slurry and the bottom, with unbleached sulphate coniferous wood pulp board as a surface slurry layer, into a paper with not only the physical structure to achieve a reasonable product quality requirements, but also a reasonable use of fiber resources. Based on this consideration, the design of three-flow system is independent of the sizing and selection of domestic and foreign advanced equipment to meet the quality requirements of cardboard vermicelli and the smooth operation of high-speed paper machine. The design includes mapping serofluid balance calculation, equipment selection and calculation, workshop equipment layout, equipment levation, the whole process flow diagram and general layout of the rendering plant. By beating the system and process flow design, production paper machine systems to master the technology and process design of the preliminary master procedures and working methods.
