摘　　要：聚酯生产所需的热量传递是通过有机热载体强制循环来完成。目前主流的导热油加热系统是将导热油直接加热,通过高温油泵进行强制液相循环,将加热后的导热油送到用热设备,换热完成后再由用热设备循环至锅炉区再加热,形成一个完整循环的加热系统。普通的燃煤锅炉的能源利用效率仅有80%~85%,未被充分利用的热量往往造成了能源浪费。通过配置耐高压换热器,利用高压水蒸气对循环的有机热载体供热,将导热油顺利地加热到325~330℃,替代厂区内原有的锅炉加热有机热载体,此方式具有换热效率高、日常维护少及运行稳定等诸多优点,可为相关的研究提供一定的借鉴。The heat transfer required for polyester production is achieved through forced circulation of organic heat carriers.The current mainstream heat transfer oil heating system directly heats the heat transfer oil,which is forced to circulate in the liquid phase through a high-temperature oil pump.The heated heat transfer oil is then sent to the heating equipment,which then circulates to the boiler area for further heating,forming a complete cycle of heating system.The energy utilization efficiency of ordinary coal-fired boilers is only 80% to 85%,and the underutilized heat often leads to energy waste.By configuring a high-pressure heat exchanger and utilizing high-pressure water vapor to heat the circulating organic heat carrier,the heat transfer oil is smoothly heated to 325~330℃,replacing the original boiler heating organic heat carrier in the factory area.This method has many advantages such as high heat transfer efficiency,less daily maintenance,and stable operation,which can provide some reference for related research.
