AI Technical Summary
Existing technologies for treating high-salinity wastewater from power plants suffer from problems such as high energy consumption, inability to recycle water resources, easy equipment corrosion, and high maintenance costs, and also have limited applicability.
A heat pump coupled spray evaporation system is adopted. By combining the evaporation tower and the spray tower, the heat pump unit realizes heat recovery and transfer. Combined with atomized spray and countercurrent contact design, it treats high-salt wastewater and recovers condensate and salts.
It achieves efficient and energy-saving wastewater treatment, with a condensate resource reuse rate of 85% and a salt recovery rate of over 90%, reducing the risk of equipment corrosion. It is stable in operation and easy to maintain, and is suitable for high-salt wastewater treatment in multiple industries.
