1北京理工大学珠海学院 2020 届本科生毕业设计某塑料厂注塑机余热回收方案设计某塑料厂注塑机余热回收方案设计摘 要在我国，有许多塑料加工企业，但是许多企业没有对注塑机产生的余热进行有效利用，因此造成资源浪费。高温余热利用技术已经非常成熟，并发挥出明显的经济效益，但中低温余热利用还有进一步开发的空间。本设计以某塑料厂注塑机余热回收方案设计为模型，如果单纯设置在注塑机熔胶筒加热段的四周安装余热收集装置，有可能造成资源浪费，效率不高，加大环境污染等不利情况。为了避免上述情况发生，还可以把回收的热量在塑料厂其他用能的地方使用，是一种比较有效的方法。此次设计，通过已知的满足产量的要求，合理地对注塑机进行选型，以及对整个系统进行设计和相应的选择设备，从而进行注塑机热负荷的计算；汽水系统的设备选择与计算，供水主要管路管径的计算；废气余热利用装置中换热器的选择与计算；管道敷设与保温的计算；热经济性评价等。关键词：高温余热利用技术；注塑机；熔胶筒；热经济性评价2北京理工大学珠海学院 2020 届本科生毕业设计Design of Heat Recovery Project for Injection Molding Machine in a PlasticIn China, there are many plastics processing enterprises, but many enterprises do not take effective use of the heat generated by injection molding machine, resulting in a waste of resources. High temperature heat utilization technology has been very mature, and play a significant economic benefits, but there is still room for further development of low temperature heat utilization. In order to avoid this, but also can be recycled heat in the plastics plant to use other places, is a more effective way. Equipment selection and calculation of steam water system, calculation of main pipe diameter of water supply; Selection and calculation of heat exchanger in heat utilization equipment with exhaust gas outlet; Pipe laying and insulation calculation; Thermal economy evaluation, etc. Abstract Keywords: heat utilization technology of high temperature heating; injection molding ...
