摘要
对某厂17.5万t/a焦油加工装置的蒸馏工序近两年生产的热量供应情况进行跟踪调查,利用夹点原理的热级联算对两年的数据进行分析,发现有0.289 6 GJ/t以上的热量可以被回收利用,根据该厂目前的情况,提出了使用热管换热器来回收低位能量,利用夹点技术来设计改造工程的换热网络,加强保温设备的安装,仅蒸馏工序,全年可产生110多万元的节能效益.
Used the heat-grade unite calculation of the pinch technology to analyse tne dates of the two years＇ production heat supply of a factory with 175 000 t annual processing plant in tar distillation section, it was found that more than 0. 289 6 GJ/t energy can he reused. According to the present situation, heat-pipe technology was advanced to recover the exhaust heat and low potential energy, the pinch technology to design the heat exchange network of the new project and stress on the installation of the heat preservation fixture, only the working procedures of distillation can produce the energy benefit of one million and one-hundred thousand yuan annual.
