Abstract:In order to deal with the problems such as high energy consumption in gravure printing equipments and pollution from exhaust gas emission, the solutions to energy saving in gravure press hot air drying, process of comprehensive govern volatile organic compounds (VOCs) as well as recycling use of major equipments and techniques were studied based on waste heat from heat source in gravure printing enterprises. The practical schemes for energy conservation and emission reduction were put forward. The integration of thermal combustion oxidation devices and hot water two section type lithium bromide absorption chiller machines to reduce the high cost of thermal combustion oxidation devices were also researched. The results showed that the printing enterprises could save up to 20%~40% operation power in three aspects, namely, hot air drying system, integrated use of organic exhaust gas and recycling of waste heat from heat source.
