| Abstract: | Huge amount of waste heat exists in printing and dyeing wastewater for its large rate of flow. Second stage heat pump system using medium high and medium low refrigerants is designed for waste heat recovery from printing and dyeing wastewater, aiming to provide heat for different printing and dyeing process. Meanwhile, the complex water quality of wastewater can cause severe fouling problem in heat exchangers of heat pump system. A fouling monitoring system is designed and relation between fouling and heat transfer is comprehensively analyzed in this study, by which the cleaning period can be predicted and cleaning strategies can be given. This study will provide the reference for waste heat recovery from printing and dyeing wastewater with fouling problem using heap pump system. |
