摘要：
The spray flash technology has become one of the effective methods to solve the shortage of fresh water resources due to its low energy consumption, good separation effect and high cooling capacity. Based on the spray-assisted low-temperature desalination technology, this paper develops the thermodynamic calculation of the internal heat and mass balance of the system, and studies the effect of the spray flash system's operating stages and the top brine temperature on the flash evaporation effect. The research results show that a higher top brine temperature can significantly improve production efficiency. When the top brine temperature is 363 K, the productivity is 3.325 kg/s and the performance ratio is 0.627. Response surface method is used to optimize the spray flash evaporation system, determine the best operating conditions of the system and the model relationship of each response. And the best parameters of the system for desalination are obtained: the top brine temperature is 343 K, the seawater inlet flow rate is 10 kg/s, the cooling water inlet temperature is 303 K, and the cooling water inlet flow rate is 9.5 kg/s. © 2021, Editorial Board of CIESC Journal.
