摘要磷酸树脂是带有官能团(有交换离子的活性基团)、具有网状结构、不溶性的高分子化合物。通常是球形颗粒物。功能：它能在液相中与带相同电荷的离子进行交换反应，此交换反应是可逆的，即可用适当的电解质冲洗，使树脂恢复原有状态，可供再次利用（再生）。
本设计的重要特点在于采用了磷酸树脂的一体化生产，采用低温聚合，降低生产成本、提高灵活性。结合原料和制品的要求，根据对聚合物树脂技术性能要求、单体的性质、聚合热的排除等原则，本设计选用半连续悬浮聚合工艺。该工艺在实际生产中有着多方面的优势，如：保证体系温度恒定和聚合反应平稳进行，避免放热高峰的出现；可有效控制悬浮聚合物的共聚组成；悬浮聚合物粒度、分子量分布较窄；悬浮聚合体系稳定性高；缩短生产周期，提高生产效率等。
本设计对生产磷酸树脂的主要生产设备进行了设备选型及设计，并确定了相应的技术参数。生产涉及的主要设备有反应釜、换热器、高位槽、过滤机、真空泵、计量泵等，根据实际生产条件，提供了所选设备和相应的生产厂家。其中，反应釜的选型和列管式换热器的设计是重点。本设计对反应釜的设计进行细化，囊括了材质、釜盖、搅拌、夹套、轴封等的选择。遵照实现工艺条件、安全可靠、经济合理、便于操作等原则，确定换热器的流程、流速、载热体、换热终温，并在估算换热面积的基础上，对换热器的工艺结构尺寸进行确定，完成列管式换热器的设计。
根据年产500吨磷酸树脂车间工艺设计进行了车间布置设计。本设计中，车间厂房采用长方形双层厂房。厂房的尺寸(长×宽×高)为18m×6m×10m。长方形厂房便于作全厂总平面布置，节约用地，方便设备排列，便于安排交通和出入口，有较多墙面提供给自然采光和通风设计使用。而磷酸树脂的厂房高度要求较高，采用双层厂房利用率高，并且本设计留有空间便于扩大生产。
本设计也充分考虑了人员安全和环境保护方面的问题。在生产过程中，要求生产人员严格遵守操作规程，做好毒性防护措施，并经常参加相关培训，了解相关信息。8737
Abstract
Phosphoric acid resin is insoluble polymers with functional groups (active group exchange ions), with a net structure,. Function: it can exchange reaction in ionic liquid phase and with the same charge, this exchange reaction is reversible, i.e. using appropriate electrolyte flushing, the resin is to restore the original state, can be used again (regeneration).
This design is the important characteristics by the Phosphoric acid resin integration of production, without the high temperature polymerization, reduce the production cost, improve flexibility.Combined with the requirements of raw materials and products, according to polymer resin technology performance requirements, the nature of the polymerization monomer, hot elimination of principle, this design choose semi-continuous suspension polymerization process. This process in practical production has various advantage, such as: guarantee system temperature constant polymerization and smooth, avoid the appearance of exothermic peak; Can effectively control the suspension of polymer copolymerization; Suspension polymer particle size, narrow the molecular weight distribution; Suspension polymerization system high stability; Shorten production cycle, improve the production efficiency, etc.
This design to production Phosphoric acid resin main production equipment of the equipment selection and design, and determine the corresponding technical parameters. Production involves main equipment is the reaction kettle, heat exchanger, high trough, filter, vacuum pump, metering pump and so on, according to actual production condition, provides the selected equipment and the corresponding production manufacturers. Among them, the reaction kettle of the selection of the tube heat exchanger and the design is the key. The design of the design of the reaction kettle thinning, include the material, the kettle cover, mixing, clip set, the shaft seal and choice. Follow the realization process condition, safe and reliable, reasonable economy, easy operation and principle, to determine the flow rate and heat exchanger flow, heat body heat, the terminal temperature, and estimates of heat transfer area, on the basis of the technology of the heat exchanger structure size determined, complete with the tube heat exchanger design. 年产500吨磷酸树脂车间工艺设计:http://www.751com.cn/huaxue/lunwen_7181.html
