年产45万吨双胶纸造纸车间初步设计本科毕业设计.doc

摘 要 主要进行了年产45万吨（70g/m2）胶版纸造纸车间的初步设计。设计的内容包括工艺论证、设备论证、一些关键设备的选型计算，浆水平衡计算。绘制完成工艺流程图、车间平面布置图和厂房立面图。 设计中采用了voith-ditifomer夹网纸机，设计车速为2000m/min，幅宽为9770mm。 造纸车间采用了两层布置方式。浆料配比采用了20%BCTMP、70%阔叶浆和10%针叶浆三种原料进行抄造。打浆设备有锥形磨浆机和盘磨机。还使用了HYDROMIX高浓混合设备。 采用了AKD中性施胶和表面施胶（MSP），AKD用量为0.16%—0.25%；表面施胶剂用量为0.002%-0.003% ；加填物GCC用量为15%；助留剂CPAM和膨润土添加量分别为300ppm和3000ppm等。 关键词：双胶纸 造纸车间 工艺平衡计算 车间平面布置 Abstract Mainly has carried on the annual output of 450000 tons (70 g/m2) for preliminary design of offset paper papermaking workshop. Design content including technology demonstration demonstration, some key equipment selection, equipment, water balance calculation. Mapped process flow diagram, workshop floor plan and elevation. Voith is adopted in design - ditifomer net machine, the design speed of 2000 m/min, width is 9770 mm. Papermaking workshop uses two layers of arrangement. Ratio of slurry used 20% BCTMP, 70% 10% of the hardwood pulp and softwood pulp three kinds of raw materials to manufacture paper with pulp. Beating equipment have tapered pulping machine and plate mill. Also used the HYDROMIX high consistency mixing equipment. Adopted the AKD neutral sizing and surface sizing (MSP), dosage of AKD was 0.16% - 0.25%; Surface sizing agent is 0.002% - 0.003%; Loading content GCC dosage is 15%; CPAM retention agent and bentonite added quantity to 300 parts per million and 3000 PPM, respectively.
