摘　　要：印染厂废水废气温度高、工艺水和空气温度低,可通过热交换器的热交换等,将废水废气中的热量传递给工艺用水或空气,以达到节约能源、提高生产效率的目的。文章论述了纺织印染行业余热回收利用的现状,阐述了印染余热的主要来源,简要介绍了目前印染废水和废气余热回收利用的技术及装置,评价了余热回收在印染行业的运用潜力。While the temperature of wastewater and exhaust gas in printing and dyeing mill is high, that of process water and air is low. But through heat transfer in heat exchanger, etc, we can transfer the heat of wastewater and exhaust gas to process water and air, so as to achieve the purpose of save energy and improve production efficiency. The paper discussed current status of waste heat recovery in dyeing and printing industry, expounded the main source of dyeing and printing waste heat, briefly introduced recycling technology and device of waste heat of textile wastewater and exhaust gas, and evaluated the use potential of waste heat recovery in dyeing and printing industry.
