Abstract

本发明涉及片材加工技术领域，具体涉及一种空压机余热回收利用的制氮方法及装置，其中，一种空压机余热回收利用的制氮方法，包括以下步骤：S1：启动制氮装置，进行制氮工作，实时采集制氮装置中各需要加热部位的温度信息，根据预设的划分规则梯度动态划分若干个需要加热部位的供热优先级，得到供热顺序表；S2：由制氮装置内设有的空压机本体为制氮工作提供压缩空气，收集空压机本体工作时产生的余热；S3：根据供热顺序表传递空压机本体工作时产生的余热，由相应的热量传递介质对需要加热部位供热。本发明能够在实现制氮工作的同时，通过对空压机本体余热的收集及传递工作，实现余热的高效传递和利用，从而减少制氮装置的能耗成本。
