AB  - A novel zero-liquid discharge (ZLD) technology for desulfurization wastewater 
      treatment is put forward in this paper. A ZLD reconstruction project performed on 
      2 x 320 MW desulfurization system was taken as the research object, to study the 
      evaporator structure and the key factors affecting spray evaporation through CFD 
      numerical simulation. The result shows that when the evaporator diameter is 
      2.4 m, the central density difference and the temperature difference of 
      evaporator outlets are 0 kg/L and 0 degrees C, under this condition, the wall sticking 
      can be avoided effectively, and the uniformity of evaporator's outlet flow field 
      is improved. As for the same amount of wastewater, small atomized particle size, 
      high flue gas flow rate and high flue gas temperature are conducive to complete 
      evaporation, and the optimum atomized particle size is 100-150 mum, flue gas 
      velocity is 3-4 m/s and flue gas temperature is 250-260 degrees C. In order to reduce 
      adverse impact on the main flue duct, the optimized design scheme that extracting 
      flue gas before and after the air preheater is put forward in the purpose of 
      energy saving.
