Abstrakt:

It’s a new technology for the concentration and reduction of desulfurization wastewater by the indirect air cooling tower. In this paper, indoor experiments are conducted to explore the evaporation characteristics of the evaporation tower and the evaporation law of desulfurization wastewater in the filler and analyze the factors affecting the evaporation characteristics, and a power plant adopting this technology is tested to verify the conclusion of the indoor experiments. The results show that the evaporation rate of the evaporation tower is positively correlated with the cross-sectional wind speed, water spray density, packing height and other parameters, and the influence of the interrupted wind speed on the evaporation rate is the most significant. The difference of vapor pressure has a positive linear relationship with that of mass fraction of the air in inlet and outlet, and the results of model test conform to those of actual one basically. On the condition of ventilation rate of 817.56m³/s, the evaporation efficiency of a mechanical ventilation cooling tower with a drenching area of about 400m² can reach 16.2-18.4t/h, which basically meets the engineering needs of desulfurization wastewater concentration and reduction in millions of thermal power plants.
