Abstract

In order to accurately simulate the evaporation characteristics of salt-containing desulfurization wastewater in high temperature flue gas, five simulation schemes for droplet evaporation of desulfurization wastewater were discussed based on DPM model of FLUENT platform and combined with the actual composition of desulfurization wastewater. A simulation scheme for realizing the influence of soluble salts and suspended solids on the evaporation of wastewater droplets was determined. The differences of evaporation characteristic parameters such as evaporation time, evaporation distance, particle size change and mass change of wastewater droplets obtained under different schemes were explored, and the evaporation characteristics of wastewater with different salt content were studied. The results show that the evaporation characteristics of different schemes are different. It is recommended to use the evaporation simulation scheme considering the actual composition of desulfurized wastewater in the simulation; The greater the salt content, the shorter the time and distance required for evaporation of waste water droplets. Under the research conditions in this paper, when the salt content of wastewater is doubled, the particle size of remaining particles increases by 10.3%, the relative mass of remaining particles increases by a percentage of 2.3, the total evaporation time and the total evaporation distance decrease by 6% on average.
