| 摘要在科学技术飞速发展的今天，能源成为了发展国民经济的重要物质基础。而余热作为一种二次能源，它的回收利用自从在“九五”的节能规划里被提出，持续至后来的“十一五”规划，逐步发展的成熟起来。近年来，随着中国节能战役的打响，余热回收技术因对于废热的有效利用而备受关注。汽车轮毂涂装生产线中的烘干炉设备能产生大量余热，目前国内涂装生产线均采用将废热烟气直接排放至厂房外，从而造成一定的环境污染和能源流失。30604 本文针对江苏苏美达车轮有限公司涂装生产线实际情况，基于行业中铝合金轮毂涂装生产线的调研以及对目前余热回收利用技术的研究，针轮毂喷涂过程中产生的余热，以热管元件为设计基础，以热管换热器为主要零部件，设计一套余热回收利用系统——工件快速降温通道。目前，国内轮毂生产企业约400家，因而工件快速降温通道可作为针对该型企业的专用装备进行推广。 关键词 余热回收 热管 热管换热器 工件快速降温通道 毕业论文设计说明书外文摘要 Title Design of waste heat recovery and utilization system for wheel production process Abstract With the rapid development of science and technology, energy has become an important basis for national economy development. As a kind of second energy, waste heat recycling was proposed in the energy saving plan of “The Ninth Five Plan”, has been extended to the subsequent “The Eleventh Five Plan”, the development has experienced ups and downs. Recently, when the battle of China's energy saving is becoming more and more fiercely, waste heat recovery technology for the efficient utilization of waste heat has gradually seized the people's eyes, and has become the focus all around the world. The drying furnace equipment in the automobile wheel hub coating production line produces a lot of waste heat, at present, the waste heat of flue gas is discharged directly to the workshop in domestic rim production line, which leads to a certain environmental pollution and energy loss. In this paper, take the coating production line of Sumec Wheel Co. Ltd in Jiangsu for an example, we made some investigations and researches on the coating production lines of aluminum alloy wheel in the mechanical manufacturing industry. This paper studies the principle of waste heat generation during spray wheel spraying, design the heat pipe components, use the heat pipe heat exchanger as the main parts, and finally design a workpiece cooling passage. At present, there are about 400 wheel rim manufacturing enterprises, therefore, the proposed workpiece cooling passage can also be considered as a useful special equipment for other similar enterprises.
