技术领域Technical field
本发明涉及了催化化学反应领域的一种加热装置，尤其涉及一种基于甲醇燃烧反应的可移动式加热装置。The present invention relates to a heating device in the field of catalytic chemical reactions, and in particular to a movable heating device based on methanol combustion reaction.
背景技术Background technique
从古至今，热量的获取伴随着人类社会的进步与发展。在现代社会中，无论是日常生活、工作需求，还是科研实验，在很多场景中都需要获取热量，这时加热装置显得不可或缺。现有的加热装置中，大多数都是通过电热阻丝进行加热，即通过将电能转化为热能实现加热；这种加热方式所需的电量较大，往往需要接入220V市电进行电量的供给。但随着社会的不断发展，人类生活方式的不断更新，对于可移动便携式加热装置的需求日益增加。From ancient times to the present, the acquisition of calories has been accompanied by the progress and development of human society. In modern society, whether it is daily life, work needs, or scientific research experiments, heat needs to be obtained in many scenarios, and heating devices are indispensable at this time. Most of the existing heating devices are heated by electric heating resistance wires, that is, heating is achieved by converting electrical energy into thermal energy. This heating method requires a large amount of electricity, and often needs to be connected to 220V mains for power supply. . However, with the continuous development of society and the continuous updating of human lifestyles, the demand for removable and portable heating devices is increasing day by day.
甲醇具有能量密度高、来源广泛、可再生、氢碳比高、储运方便等突出优点，其与氧气在催化剂的作用下，能够发生甲醇燃烧反应，生成水和二氧化碳的同时能够释放出大量热量，从而实现化学能向热能的转化；甲醇燃烧反应具有反应速度快，反应剧烈等特性，是一种很好的化学加热方式。Methanol has outstanding advantages such as high energy density, wide source, renewable, high hydrogen-to-carbon ratio, and convenient storage and transportation. Under the action of a catalyst, methanol can undergo a methanol combustion reaction with oxygen, generating water and carbon dioxide while releasing a large amount of heat. , thereby realizing the conversion of chemical energy into thermal energy; the methanol combustion reaction has the characteristics of fast reaction speed and violent reaction, and is a good way of chemical heating.
通过基于甲醇燃烧反应的加热装置设计，可以大大降低加热装置对于电量的需求，通过采用移动电源即可实现较长时间的加热，大大提高了加热装置的便携性；同时通过对于结构的设计，可以实现加热面积和加热区域的控制，从而实现针对性加热，在节约能量的同时提高加热效率。Through the design of the heating device based on the methanol combustion reaction, the power demand of the heating device can be greatly reduced. By using a mobile power supply, longer heating can be achieved, which greatly improves the portability of the heating device. At the same time, through the design of the structure, it can Realize the control of heating area and heating area to achieve targeted heating and improve heating efficiency while saving energy.
现有技术公开了一种节能型催化燃烧反应器，该反应器具有排气口、进料管、风机部件、填充机构、导热机构、换热器以及甲醇储存容器，该反应器以甲醇裂解制氢后含氢尾气和空气中的氧气为主，以甲醇燃烧反应为辅，产生热量用于其他反应原料的预热，以节约能源。但该装置主要用于反应尾气的后处理，辅助器件繁多，装置系统较为庞大，难以实现可移动化应用。The prior art discloses an energy-saving catalytic combustion reactor. The reactor has an exhaust port, a feed pipe, a fan component, a filling mechanism, a heat conduction mechanism, a heat exchanger and a methanol storage container. The reactor is produced by methanol cracking. After hydrogenation, the hydrogen-containing tail gas and oxygen in the air are mainly used, supplemented by the methanol combustion reaction, to generate heat for preheating other reaction raw materials to save energy. However, this device is mainly used for post-processing of reaction exhaust gas. It has many auxiliary devices and the device system is relatively large, making it difficult to realize mobile application.
现有技术还公开了一种基于甲醇触媒加热的供热装置，该供热装置具有换热筒、加热管、催化饼、蓄热饼等部件，该装置将雾化状甲醇与空气吹入换热筒中与催化饼接触，发生化学反应产生热量对蓄热饼和换热筒进行加热，该方案无火焰，废气仅有二氧化碳，使用安全可靠且无污染。但该装置本体为一个换热器，只能针对气体和液体进行加热，无法准确控制加热温度，且无法对加热面积和加热区域进行控制，整体加热效率不高。The prior art also discloses a heating device based on methanol catalyst heating. The heating device has a heat exchange cylinder, a heating tube, a catalytic cake, a heat storage cake and other components. The device blows atomized methanol and air into the exchanger. The thermal cylinder contacts the catalytic cake, and a chemical reaction occurs to generate heat to heat the thermal storage cake and heat exchange cylinder. This solution has no flame, and the exhaust gas is only carbon dioxide. It is safe, reliable and pollution-free. However, the device body is a heat exchanger, which can only heat gas and liquid. It cannot accurately control the heating temperature, and cannot control the heating area and heating area. The overall heating efficiency is not high.
在以往公开的发明专利中，尚未发现针对可移动式的基于甲醇燃烧反应的加热装置。采用甲醇燃烧反应进行热量释放，以化学能转化为热能，大大减少加热装置对于电量的需求，提高可移动性；通过相应的结构设计，实现对各种形态的物体进行加热，且对加热面积及区域进行控制，以提高加热装置整体的加热效率；因此有必要设计一种基于甲醇燃烧反应的可移动式加热装置，并进一步优化结构，实现更多场景下的高效应用。In the invention patents disclosed in the past, no portable heating device based on methanol combustion reaction has been found. The methanol combustion reaction is used to release heat, and chemical energy is converted into thermal energy, which greatly reduces the power demand of the heating device and improves mobility; through corresponding structural design, various forms of objects can be heated, and the heating area and The area is controlled to improve the overall heating efficiency of the heating device; therefore, it is necessary to design a movable heating device based on the methanol combustion reaction, and further optimize the structure to achieve efficient applications in more scenarios.
