摘　　要：针对空压机使用过程中大部分能量被浪费的情况,提出了将空压机热能回收用于UHT杀菌系统中料液预热的方案,设计了一种空压机热能回收系统。该热能回收系统采用热交换器和保温管道实现了空压机与UHT杀菌系统的联接,并利用水进行循环。空压机的热能通过热交换器进行回收,并经过保温管道输送到饮料UHT杀菌系统处,再利用热交换器用于饮料料液UHT杀菌的预热过程。经过实际改造应用和计算,该热能回收系统每天可减少能耗9 500 k W·h,节约蒸气15 t,每年可节省开支93.4万元。研究结果表明,该空压机热能回收系统具有很好的实用价值和显著的经济效益。Aiming at most of the energy waste in the process of air compressor, a scheme that the heat recovery of air compressor used for the beverage liquid preheating in UHT sterilization system was put forward, and an air compressor heat recovery system was designed. In the heat recovery system, two heat exchangers and some thermal insulation pipes were used for the connection between air compressor and UHT sterilization system, and water was running round in the pipes. With a heat exchanger, the heat of air compressor was recycled by water. Then the water flowed to the UHT sterilization system and was used for the beverage liquid preheating by another heat exchanger. Through practical application and calculation, the air compressor heat recovery system could reduce 9 500 kW · h of energy and 15 tons of steam per day. And it could reduce ￥ 170,000 each year. The results indicate that the air compressor heat recovery system has good practical value and significant economic benefits.
