红外加热与干燥是利用热物体源(通常使用各种红外加热器)所发射出来的红外线,照射到被加热干燥的物料上,并且被吸收后转换成热能,从而达到加热与干燥目的的一门技术。由于它具有耗电少、加热干燥物料的速度快和质量好、以及较易实现生产过程的连续化、自动化等优点,已在国内外被作为一门节能技术而得到广泛应用。我国国务院1978年第42号文件将它列为国家重点推广项目;在美国,有人把红外加热列为120种节能措施中的第3种;日本于1978年制订了有关节能工作的月光计划,陶瓷材料的红外辐射节能技术也作为一项重要内容被列入。几年来推广应用这门技术的实践表明,它已为国家节能作出了很大的贡献。前些日子,曾有少数人议论,指责红外加热干燥技术中出现的弊病,甚至提出要赶快限制远红外加热技术的推广。本文仅就此谈谈我们的看法。 Infrared heating and drying is the use of hot objects source (usually using a variety of infrared heaters) emitted by the infrared radiation is heated to dry material, and is absorbed into heat, so as to achieve the purpose of heating and drying door technology. It has been widely used as an energy-saving technology both at home and abroad because of its advantages of less power consumption, faster and better quality of heating and drying materials, and easier realization of the continuous and automatic production process. In 1978, No. 42 of the State Council of China listed it as a national key promotion project; in the United States, infrared heating was listed as the third of the 120 kinds of energy-saving measures. In 1978, Japan enacted the Moonlight Plan on energy conservation and ceramics Material infrared radiation energy-saving technology is also included as an important part. The practice of popularizing and applying this technology in recent years shows that it has made a great contribution to the national energy conservation. A few days ago, there were a few people who criticized the shortcomings of infrared heating and drying technology, and even proposed to quickly limit the promotion of far-infrared heating technology. This article only talk about our views on this.
