Abstract :
The experimental research was carried out about process of SO2 removal in flue gas using white lime slurry atomization, and with the method of non-contact on-line measuring for SO2 concentration in riser. The temperature distribution of slurry atomization drying was measured by new sandwich structure thermocouple with air pump. The results showed: The maximum SO2 removal and temperature decreasing amplitude were got at a distance 200mm from the nozzle. Atomization temperature region was bimodal symmetric distribution. Evaporation intensity from high to low along the axis. The SO2 removal rate was first increased and then decreased, SO2 removal and evaporation strength biggest regional overlap. Two-stage spray desulfurization efficiency increased 11.9%.
