摘要

当今世界, 由于能源需求上升所导致的能源供应安全和温室气体排放正严重威胁着能源可持续发展, 推进能源结构改革迫在眉睫。微波作为一种清洁、环保的绿色能源, 近年来发展迅速。与传统加热方式不同, 微波加热是通过极性分子的随机运动而产生热量。这导致微波加热具有选择性加热、升温速度快、易于控制、加热效率高等优势。这使得微波可以在推进能源结构改革中做出贡献。本文调查了在不同行业中使用微波技术节能减排的情况, 发现在炼铁行业中, 微波可以加快铁矿石还原的时间, 减少二氧化碳的排放, 同时在铁矿石预处理过程中可以使铁矿石变得更加容易破碎和磁选。在食品行业中, 微波可以缩短食品烹饪和干燥所需的时间, 并最大程度上保留食品的营养成分。在废物回收领域, 微波在更短的时间内缩小了底放射性废物的体积, 提高了废旧橡胶的脱硫效率。在布杜尔反应中, 微波降低了反应所需的温度, 提高了二氧化碳的转化率。总结了微波技术的优点后, 本文还分析了微波技术目前存在的缺陷, 介绍了微波相关的专利, 最后对微波技术的未来进行了展望。

Abstract

In today's world, security of energy supply and greenhouse gas emissions due to rising energy demand are seriously threatening sustainable energy development, and it is urgent to promote energy structure reform. Microwave, as a clean and environmentally friendly green energy source, has developed rapidly in recent years. Unlike traditional heating methods, microwave heating generates heat through the random motion of polar molecules. This results in microwave heating having the advantages of selective heating, fast temperature rise, easy control and high heating efficiency. This allows microwaves to make a contribution in advancing the reform. of the energy mix. This paper investigates the use of microwave technology in different industries to save energy and reduce emissions. It finds that in the ironmaking industry, microwaves can speed up the reduction time of iron ore, reduce carbon dioxide emissions, while making iron ore more easier to crush and magnetically sort during iron ore pretreatment process. In the food industry, microwaves can reduce the time required to cook and dry, and maximise the retention of nutrients in food. In the field of waste recycling, microwaves reduce the volume of bottom radioactive waste in a shorter time and improve the efficiency of desulphurisation of waste rubber. In the Budur reaction, microwaves reduce the temperature required for the reaction and increase the conversion of carbon dioxide. After summarising the advantages of microwave technology, this paper also analyses the current shortcomings of microwave technology, introduces microwave-related patents and concludes with an outlook on the future of microwave technology.
