Dual-effect evaporator

The dual effect evaporator is an advanced energy-saving concentration system that employs two evaporators connected in series. Its core principle involves using the secondary steam generated from the first effect as the heating source for the second effect, enabling cascading energy utilization and significantly improving thermal efficiency. This design provides notable advantages including rapid evaporation speed, short material heating time, high concentration ratio, and reduced energy consumption. It also demonstrates strong adaptability to various water qualities with low feed requirements. While the system requires a relatively larger footprint and involves higher operational costs compared to single-effect units, its outstanding energy efficiency makes it ideal for large-scale applications. Key performance parameters include evaporation capacity, steam consumption rate, heat transfer coefficient, concentration ratio, and operating temperature range. Suitable for industrial wastewater concentration, chemical processing, and food and pharmaceutical industries, the double effect evaporator offers an optimal balance between performance and economy for medium to large-scale evaporation needs.
