Water generating system

Abstract

This invention provides a water generation system. The water generation system includes a raw water introduction device, a water temperature regulation device, a filtration device, and a steam recompression evaporation device. Therefore, the water resource utilization rate can be improved through the filtration device, and the evaporation efficiency can be improved and the overall energy consumption can be reduced through the steam recompression evaporation device.

Claims
