ABSTRAKT
Spray evaporation desalination technology has the potential to improve the performance of thermal desalination plants and make thermal desalination more competitive and appealing. For a better understanding of the seawater evaporation process, a mathematic model has been presented with consideration of the motion, heat transfer of the droplet, and performance of the evaporator based on droplet analysis. The model has been validated against experimental data, and simulation results showed good agreement with experiments with a discrepancy below 10%. The model can be used to evaluate water productivity and thermal utilization accurately, which are critical to the design of the evaporator. Research results revealed that smaller droplets and lower initial velocity lead to a high thermal utilization, while superheat degree has a marginal effect on thermal utilization. The merits of flash evaporation can make it operate at larger superheat with higher thermal utilization and water productivity while multi-stage flash distillation (MSF) needs more stages to eliminate non-equilibrium temperature differences.
