AI Technical Summary
Existing desulfurization wastewater treatment technologies suffer from high equipment investment, high energy consumption, low thermal energy utilization, and poor system stability. In particular, independent fluidized bed drying requires additional steam and electricity consumption and is prone to wall adhesion, scaling, and blockage, which affects the long-term stable operation of the system and drying efficiency.
A bypass flue gas fluidized bed drying system is adopted, which uses high-temperature and low-temperature flue gas bypass stage heat extraction to dry desulfurization wastewater using the waste heat of power plant flue gas. Combined with a dual-fluid spray gun and fixed bed design, it achieves efficient and stable drying of wastewater, and prevents wall adhesion and clogging by online flushing.
It achieves efficient utilization of flue gas waste heat, reduces energy consumption, improves system stability and drying efficiency, ensures continuous system operation, avoids wall adhesion and blockage, and achieves efficient, energy-saving and stable desulfurization wastewater drying effect.
