Abstract
Dyeing and printing industry consumes lots of energy, involving coal, steam, water, electricity and caustic soda, etc. Any slight negligence in each process may cause severe waste. Energy conservation involves technology innovation and product upgrading in dyeing and printing process, as well as the whole process of equipment updating. Wastewater of dyeing factory contains vast waste heat, and it is highly economic to recycle the heat via selecting appropriate heat exchange equipment and recycling measures.关键词
