摘要
随着国家碳中和及碳达峰战略目标的推进实施,航运节能减排的技术也被大众所关注。由于船舶机舱内部有大功率的发动机和发电机组,故在设备工作时产生的废气余热温度极高,可高达上千摄氏度。首先将废气余热通过斯特林机转化为机械能,再通过外接发电机转化为电能。整个工作过程在降低环境温度的同时产生了电能,提升废气余热的利用效率。据初步试验,在温度为433℃时即可产生约3.3 V的电能。该装置结构简单,没有复杂的机械结构,安全性较高、可靠性强,若能在船舶机舱中多设备同时使用,对于实现碳中和及碳达峰目标拥有积极的助力。
With the implementation of the national carbon neutralization and carbon peak strategy,the technology of shipping energy conservation and emission reduction has also been concerned by the public.As there are high-power engines and generator sets in the engine room of the ship,the waste heat temperature of waste gas generated during equipment operation is extremely high,which can be as high as thousands of degrees Celsius.The device first converts waste gas waste heat into mechanical energy through Stirling machine,and then converts it into electrical energy through external generator.The whole working process produces electric energy while reducing the ambient temperature,and improves the utilization efficiency of waste heat.According to the preliminary experiment,about 3.3 V electric energy can be generated when the temperature is 433℃.The device has simple structure,no complex mechanical structure,high safety and strong reliability.If multiple equipment can be used in the marine engine room at the same time,which will have a positive help to achieve the goals of carbon neutralization and carbon peak.
