本文介绍的废热回收技术是前川制作所与日立造船株式会社,受通产省技术院的委托而进行研究与开发的废热利用装置,属日本“月光计划”的一环。目前,如钢铁厂等各工厂里的废热均被排放到水和大气中。据称未回收的热能占40％,而未回收热量中的60％是以30～60℃的低温水(即温排水)被排出的。本研究项目其目的就是研制回收30～60℃低温排水的热量,用来制取100～150℃高温水的高温热泵装置。以前的热泵在空气调节中的
The waste heat recovery technology introduced in this paper is a waste heat recovery device that was researched and developed by the former Chuan Manufacturing Co., Ltd. and Hitachi Shipbuilding Co., Ltd., commissioned by Japan’s Ministry of International Trade and Industry, and is part of Japan’s “Moonlight Plan.” At present, waste heat from factories such as steel mills is discharged into the water and the atmosphere. It is claimed that 40% of the heat is not recovered, and 60% of the un-recovered heat is discharged at a low temperature of 30-60 ° C (ie, warm water). The purpose of this research project is to develop the recovery of 30 ~ 60 ℃ low-temperature heat of the heat, used to make 100 ~ 150 ℃ high temperature water heat pump device.
