尼龙66毕业设计解析

摘要

聚酰胺66在聚酰胺材料中有较高的熔点。它是一种部分结晶材料。聚酰胺66在较高温度下也能保持较强的强度和刚度。聚酰胺66在成型后依然具有吸湿性，其主要程度取决于材料组成以及环境条件。虽然聚酰胺纤维是我国最早工业化生产的合成纤维，但由于多种原因发展比较缓慢，仍有很大的发展潜力。因此对聚酰胺车间的设计和研究是很有必要的。

本设计主要是1.36×107千克/年聚酰胺66切片制造车间工艺设计中的反应器的设计，课题以及选题来源于工厂的真实设计。从聚酰胺66的发展历程和目前现状入手，对聚酰胺66工艺形成初步认识。通过聚酰胺66工艺手册，对设计的装置组成、生产方法、生产制度和工艺参数的原则正确合理的操作规程和指标。

本次工艺设计主要包括物料衡算、热量衡算和设备计算三部分。其中主要包括反应器设计计算的总传热系数、传热系数、传热面积。最后要用Auto CAD 绘制物料平衡图和带控制点的工艺流程图。

经计算得到反应器的总传热面积S=12.67m2，总传热系数k=399

利用整个平衡计算过程的参数和结论，进行设计的主体部分反应器设计。经过最后核算，本次设计符合预期目标，各项参数均已达标。

Abstract

In the materials of polyamide,PA 66 has the higher melting point.It is a partial crystalline material.PA66 will remain relatively strong strength and stiffness even at the higher temeperatures.After the molding,PA66 is still of hygroscopicity,which mainly depends on its material composition and environmental conditions.Although polyamide fiber is the first industrial production of synthetic fibers,its development has been relatively slow owing to a variety of reason.So there is still great potential for its development.So the polyamide workshop design and research is absolutely necessary.

The design is mainly about technology design of manufacture workshop of 7

polyamide 66 granule,topics and subject the real design from the kg

factory.We can make a preliminary understanding from the development process and the present situation.t\Through the operating manual of PA66,to design of device component,production method,production system and the process parameter of principle correct reasonable operation procedures and index.

The process of the design including mainly three parts:material balance,energy balance and the calculation of the equipment.Include the reactor design calculation of the total heat transger coefficient,heat transfer coefficient,heat transfer area.With Auto CAD rendering final material balance chart and take control points of process flow diagram.

The total heat transfer area of S=12.67m2 reactor is obtained throughcalculation, the total heat transfer coefficient k=399

Use the entire balance calculation process parameters and conclusions to calculate the reaction instrument.After the final accounting,this design is expected to meet the goals,all the parameters have been fulfilled.

Key words: polyamide 66; reaction instrument; technological design
