摘要
本次设计主要是对日产250吨新闻纸的抄纸车间的初步设计,主要内容是抄纸车间的工艺流程设计以及各工段工序设备图,还包括车间布置图。本设计中采用废纸浆和化学热磨机械浆(CTMP)按60:40配抄新闻纸。总的一个设计思路主要围绕新闻纸这种纸张它的特点以及自身属性,来定这一纸种的生产原料和设备选型及布置,我在这次设计中主要运用书本及新闻纸生产厂家这两大部分采集资料,再涵盖自己的思想,在老师的悉心指导下完成此文。首先我介绍了新闻纸的产品规格以及技术指标以及建厂的可行性分析,这是作局为一个设计能否符合国家以及成品有效性的规定所要求的先决条件,也是设计的一个标准。然后是一些环保上的要求,充分考虑废水、废气、废渣的循环利用,还有一些整个图纸设计的技术指标。接着是介绍新闻纸的工艺流程以及浆水平衡的计算,设备的计算与选型,原材料蒸汽及水的耗用量。最后是介绍抄纸车间的工作制度,车间定额以及人员编制。以上提到的内容都与此次设计能否作为工厂正常实施可用必须的一个理论依据。

Abstract
The graduation design topic is daily production 250 tons of newsprint paper workshop preliminary design. The main contents of the paper-making workshop as well as the process design process equipment diagram section, but also including the shop layout. This design uses waste paper pulp a hemical thermo-mechanical pulp(CTMP)press 60:40 Furnish for making newsprint paper. A total design focus on the special paper base newsprint paper features, as well as their own property, to set the paper types of production materials and equipment selection and layout. Most of the information collected in books and newsprint paper base paper manufacturer where I was used for this design mainly, and then covered his own ideas, the teacher under the guidance of this article. First of all, I introduced the newsprint paper product specifications and technical indicators, as well as the feasibility of plant analysis, it is a possibility of a design bureau for the national as well as the finished product required by the provisions of the effectiveness of pre-conditions, but also a standard design. Followed by a number of environmental protection requirements, take full account of wastewater, waste gas, waste residue recycling, as well as the overall graphic design of a number of technical paper is then introduced, as well as the process of calculating the balance for pulp and water, selecting equipment, raw materials, steam and water consumption. Finally, th
